+# Vector Store Alternatives to LanceDB (issue #12970 research)
+
+Date: 2026-06-10
+Trigger: [paperless-ngx#12970](https://github.com/paperless-ngx/paperless-ngx/issues/12970), LanceDB wheels SIGILL at import on non-AVX2 x86_64 CPUs.
+Method: deep-research web sweep (22 sources, 25 claims adversarially verified, 21 confirmed / 4 refuted) plus local empirical testing of every candidate wheel under qemu-user CPU emulation, plus a brute-force latency benchmark.
+
+## TL;DR
+
+1. **Waiting on upstream is not a plan.** The AVX2 baseline in LanceDB wheels is a deliberate, maintainer-defended build choice. The compat tracking issue (lance#2195) was closed as Stale / not_planned on 2026-01-22, the runtime-dispatch PR (lance#6630) is unmerged, and `lancedb-compat` on PyPI is a 404.
+2. **faiss is no longer a safe fallback either.** The new Meta-published faiss-cpu 1.14.2 wheel ships a single AVX2 binary and SIGILLs on pre-Haswell CPUs (verified empirically). Only the archived community 1.13.2 wheel still carries the generic fallback.
+3. **sqlite-vec is the best structural replacement.** Pure C, zero dependencies, plain SQLite file, metadata columns with SQL filtering, passes the pre-AVX2 emulation test, and brute-force search at 100K x 768 dims is ~185 ms/query, faster than LanceDB exact search on the same data.
+4. **Recommendation:** short-term, ship a pre-flight CPUID check that disables AI cleanly instead of crashing. Real fix, port `PaperlessLanceVectorStore` to a sqlite-vec backend (the method surface maps almost 1:1 onto SQL); decide then whether sqlite-vec replaces LanceDB outright or serves as the non-AVX2 fallback.
+
+## Constraints a replacement must satisfy
+
+From PR #12944 (the FAISS -> LanceDB switch) and the current `PaperlessLanceVectorStore` surface:
+
+- Embedded / file-based under `LLM_INDEX_DIR`, no extra service container.
+- Published wheels must run on pre-Haswell x86_64 (no baked-in AVX2) and on arm64.
+- Multi-process: Celery workers + granian web workers; writers already serialized via FileLock, readers must not be blocked.
+- Per-document upsert/delete; metadata filtering (EQ / IN on `document_id`).
+- Real deletes (not tombstone-forever), not loading the whole index into memory.
+- Scale target ~1K-500K chunks of f32 embeddings (384-1536 dims); exact search acceptable below ~100K rows.
+- Wrappable behind the existing llama-index `BasePydanticVectorStore` subclass shape.
+
+## Empirical SIGILL matrix (qemu-user 8.2.2)
+
+Each candidate ran a real insert + top-k search workload (50 vectors, 384 dims) natively and under two emulated CPUs. Host: Xeon E5-2683 v4 (Broadwell, AVX2), Python 3.12, manylinux x86_64 wheels as published on PyPI 2026-06-10.
+
+- `Westmere` = SSE4.2, no AVX. Same ISA class as the Atom C3758 from issue #12970.
+- `SandyBridge` = AVX, no AVX2. The Sandy/Ivy Bridge users in the upstream reports.

+
+The lancedb crash reproduces issue #12970 exactly (SIGILL during import), which validates the harness.
+
+Dependency-level isolation of the failures:
+
+- **pyarrow 24.0.0 passes on both emulated CPUs.** Its runtime dispatch is sound; the lancedb crash is entirely the lance Rust core.
+- **pandas 3.0.3 requires AVX**: SIGILL at import on Westmere, passes on SandyBridge. (numpy 2.4.6 alone passes everywhere.)
+- **milvus-lite 3.0 itself is pure Python** (the v3.0.0 release, 2026-05-13, is an explicit pure-Python rewrite; the wheel contains no native code). The SIGILLs come from its mandatory dependency stack: pandas kills it at import on Westmere, and on SandyBridge something in the pymilvus client init path (69 loaded C extensions, pandas/pyarrow/grpcio/protobuf) still executes an illegal instruction.
+
+### faiss-cpu wheel forensics
+
+The portability regression is visible in the wheel contents:
+
+- 1.13.2 (community faiss-wheels, now archived): `_swigfaiss.abi3.so` + `_swigfaiss_avx2.abi3.so` + `_swigfaiss_avx512.abi3.so`, with a runtime loader that picks by CPUID. Passes on all emulated CPUs.
+- 1.14.2 (first Meta-published wheel): a single `_swigfaiss.abi3.so` (6.1 MB) + `libfaiss.so` (14 MB). No generic variant exists, so the loader has nothing to fall back to. SIGILL on both pre-AVX2 CPUs.
+
+Pinning to 1.13.2 means pinning to an archived repo, a dead end. Worth reporting upstream to facebookresearch/faiss as a packaging regression, but do not build paperless's plan on it.
+
+## Brute-force latency (native, 100K vectors x 768 dims, top-10)
+
+| Store                                     | Insert 100K | Query      |
+| ----------------------------------------- | ----------- | ---------- |
+| sqlite-vec 0.1.9 (file)                   | 18.0 s      | **185 ms** |
+| lancedb 0.33.0 exact, no ANN index (file) | 9.1 s       | 497 ms     |
+| numpy in-memory                           | n/a         | 262 ms     |
+
+100K x 768 is already a large paperless install (the PR #12944 author's own index was ~40-53 MB, roughly 15-20K chunks). Scaling linearly, 500K rows lands near ~1 s/query for sqlite-vec, slow but usable for suggestions/chat; below 100K it is comfortably interactive. Exact search also means no recall loss, no ANN index builds, and no compaction cycle.
+
+## Per-candidate assessment
+
+### sqlite-vec 0.1.9 — recommended
+
+- **ISA:** pure C with no SIMD baseline assumptions; passed Westmere and SandyBridge. No SIGILL reports found upstream.
+- **Fit:** the `vec0` virtual table gives metadata columns (since v0.1.6) and partition keys, so `document_id` EQ/IN filtering is a SQL WHERE clause, the same shape as the current `_build_where()`. Persistence is one SQLite file; the existing FileLock writer serialization plus WAL mode covers Celery + granian (WAL readers do not block on the writer).
+- **Method mapping:** `merge_insert` -> DELETE + INSERT in one transaction; `compact()` -> no-op or `PRAGMA incremental_vacuum`; stored model name -> a one-row meta table; `get_modified_times()` -> `SELECT document_id, modified`; `vector_dim()` -> declared column type. Real deletes work (`DELETE FROM t WHERE ...`).
+- **Project health (verified 2026-06-10):** commit concentration is real, asg017 has 441 commits and the next contributor 5, and the version is still pre-1.0 (v0.1.9 stable, v0.1.10-alpha.4 of 2026-05-18 current). But the institutional backing is substantial: sqlite-vec is a Mozilla Builders project (Mozilla is the main sponsor, announced June 2024, plus Fly.io / Turso / SQLite Cloud / Shinkai), and **Firefox vendors and ships it**: `third_party/sqlite3/ext/sqlite-vec` in mozilla-central is pinned to v0.1.10-alpha.4 (vendored within days of release), gated by `MOZ_SQLITE_VEC0_EXT` for browser builds, with its own Bugzilla component (Core :: SQLite and Embedded Database Bindings) and vendoring automation. A project on the Firefox release train is unlikely to silently die; Mozilla has both the motive and the means to maintain it.
+- **ANN is no longer "never":** the vendored tree and the v0.1.10 alpha commits show IVF (+ k-means, DiskANN, rescore) actively in development (`sqlite-vec-ivf.c`, `sqlite-vec-diskann.c`, "Rename all IVF shadow tables" etc.). The original report claim that ANN never shipped (issue #25) is true for stable releases but stale as a trajectory: the >100K-row story is being built right now, likely Mozilla-driven.
+- **Risks:** brute-force only in stable releases today; effectively one code author; pre-1.0 versioning. The vec0 KNN operator support for `IN` on metadata vs partition-key columns should be verified during implementation.
+- **Version pin warning (2026-06-10 follow-up audit):** the 0.1.9 wheel is built with no SIMD flags (verified via `vec_debug()` and qemu), but the **0.1.10-alpha.4 wheel bakes in `-mavx` with no runtime dispatch** and can SIGILL on AVX-less CPUs, the same failure mode as LanceDB. Pin `==0.1.9` and audit wheel flags before any bump. Full mapping + risk register: `docs/superpowers/specs/2026-06-10-sqlite-vec-vector-store-design.md`.
+- **Deps:** zero. Removes lancedb + pylance (and their ~40 MB of wheels) if it replaces rather than supplements.
+
+### faiss-cpu — was the pre-LanceDB store; now disqualified by packaging
+
+Runtime dispatch worked in the community wheels, but paperless moved off FAISS in PR #12944 for good reasons (no metadata filtering, no real deletes, full in-memory docstore), and the 1.14.2 Meta wheels reintroduce the exact SIGILL this research is trying to escape. Going back is strictly worse than LanceDB today.
+
+### usearch 2.25.3 / voyager 2.1.0 — ISA-safe but structurally poor fits

+Both pass emulation (usearch via SimSIMD's compile-everything-dispatch-at-runtime design). Neither stores metadata or payloads: filtering is predicate callbacks (usearch) or absent (voyager), persistence is whole-index save/load files, and node content would need a SQLite sidecar maintained by the wrapper. That is the same integration work as FAISS with less ecosystem support. Only attractive if ANN performance at >500K rows ever becomes the binding constraint.
+
+### ChromaDB 1.5.9 — ISA-safe (new data), blocked on multi-process
+
+Passed both emulated CPUs (the web sweep had no surviving verified claims on Chroma; this is new evidence). But embedded `PersistentClient` does not support concurrent access from multiple processes (Chroma's documented system constraint), which Celery + granian violate immediately; the supported concurrent mode is the Chroma server, i.e. an extra container. Also the heaviest dependency tree of the candidates. Disqualified.
+
+### DuckDB 1.5.3 — ISA-safe, blocked on file locking
+
+Passed both emulated CPUs; `array_distance` over a FLOAT[n] column works fine for exact search and SQL filtering. But a DuckDB file allows either one read-write process or many read-only processes, not both at once, so granian readers would be locked out during Celery writes (today's LanceDB readers are lock-free, and SQLite WAL readers are too). The VSS/HNSW extension's persistence is still marked experimental. Disqualified for this use.
+
+### qdrant-client local mode — ISA-safe, hard multi-process lock
+
+Local mode is numpy-based and passed emulation, but it takes an exclusive portalocker lock on the storage dir; a second process gets `RuntimeError` directing you to the Qdrant server. Maintainer-confirmed as out of scope (qdrant-client#765). Disqualified.
+
+### milvus-lite 3.0 — pure Python now, still disqualified
+
+v3.0.0 (2026-05-13) rewrote Milvus Lite in pure Python (custom LSM-style engine: memtable/WAL/segments/manifest, no native code in the wheel), and the v2-era exclusive-lock behavior is gone: a second process can open the same DB concurrently (verified locally, no lock files created). Two corrections to the web-research-era assessment, in its favor. It still fails for paperless: the mandatory pymilvus dependency stack (pandas 3.x, pyarrow, grpcio, protobuf) SIGILLs on both pre-AVX2 test CPUs, so the portability problem is merely relocated, and the dependency weight is the largest of any candidate. Its concurrent-writer safety through the custom storage engine is also unproven (no documented multi-process write story for the rewrite).
+
+### numpy / llama-index SimpleVectorStore — portable but regressive
+
+Always works, but it is the load-everything-into-RAM model that PR #12944 deliberately left behind. Acceptable only as a last-resort fallback tier.
+
+### SQLite team's Vec1 (evaluated 2026-06-10, post-report; promising later, not now)
+
+The SQLite project's own vector extension (https://sqlite.org/vec1, single `vec1.c`, IVFADC+OPQ ANN plus exact NN/flat modes, L2+cosine, metadata columns with in-index filter pushdown, streaming filtered queries). Why it loses today despite the gold-standard maintainership:
+
+1. **Pre-release**: the project page says "No further features are required before first release. But: Testing is insufficient" and "almost all paths require optimization". No first release has happened.
+2. **The same SIGILL trap, documented as the build model**: recommended build is `-mavx2 -mfma`, and the docs state binaries built that way "will not work on systems that lack them". A multi-arch Makefile target exists, but compile-time SIMD selection is the design; shipping it safely for #12970-class CPUs is on the packager.
+3. **No distribution**: no PyPI wheels, no package at all; paperless would vendor and compile it for Docker AND ask bare-metal users to do the same.
+4. **Filter pushdown has no `IN`**: in-index filtering supports `<, >, =, >=, <=, IS` only. The store's primary query is `document_id IN (...)`; with vec1 that means streaming queries + JOIN post-filtering, with the manual's own documented silently-reduced-K pitfall.
+5. Rowid-keyed only (no TEXT pk; node UUIDs need a mapping table) and metadata columns are "optimized for small values (say 8 bytes)", so the node-content JSON needs a sidecar table anyway. ANN mode requires offline `vec1_train()` model training, retraining as data evolves, and rerank discipline; the untrained exact modes are usable but then vec1's distinctive ANN advantage is unused.
+
+Worth re-evaluating after its first release if it grows a packaging story; the store-behind-`BasePydanticVectorStore` design and the migration machinery make a later vec1 backend the same bounded port as this one.
+
+### Vectorlite (dark horse, not tested)
+
+SQLite extension wrapping hnswlib with Google Highway runtime dispatch; v0.2.0 explicitly fixed an AVX2-wheel crash, the exact failure mode at issue. Verification of its arm64 wheels and maintenance health was inconclusive in the web sweep and it was not in the local matrix. Could be revisited if sqlite-vec's lack of ANN ever bites.
+
+## Recommendation
+
+**Step 1 (ship now, fixes #12970):** pre-flight CPU check before any `lancedb` import: read `/proc/cpuinfo` flags (or CPUID via py-cpuinfo) for `avx2`; on failure, disable the AI feature with a clear system-check error / log line instead of crashing celery and granian. This matches the resolution the issue itself suggests and is independent of any store decision. A SIGILL cannot be caught, so the check must gate the import.
+
+**Step 2 (the real fix): port the store to sqlite-vec.** `PaperlessLanceVectorStore` was designed as a thin, self-contained adapter and that pays off here: every method maps directly onto SQL against a `vec0` table plus a small meta table. Two deployment shapes:
+
+- **(a) Full replacement** (my lean): one code path, one store to test, drops the lancedb dependency entirely, plain SQLite file artifact, and the benchmark shows exact search beating LanceDB's exact path at 100K rows. Costs: no ANN above ~100K rows (about ~1 s/query at 500K), and a one-time index rebuild on upgrade (already a routine paperless operation, `document_llmindex rebuild`).
+- **(b) Dual backend**: keep LanceDB on AVX2 hosts, sqlite-vec on the rest, selected by the step-1 CPU check. Preserves ANN for very large installs, but doubles the test/maintenance surface and keeps the lancedb dependency for everyone.
+
+Given realistic paperless index sizes (tens of thousands of chunks, not hundreds of thousands) and the cost of maintaining two stores, (a) is the better trade unless telemetry/user reports say otherwise. If lance#6630 eventually merges and lancedb wheels gain runtime dispatch, that decision can be revisited with no architectural debt.
+
+**Migration machinery (PR #12968) carries over.** The in-place LanceDB migration framework in paperless-ngx#12968 (structural migrations vs full re-embed, so users paying for embeddings only re-pay when the vectors themselves change) is needed regardless of store, and its split survives a backend swap intact:
+
+- On sqlite-vec, "structural" migrations are SQL DDL. vec0 virtual tables do not support arbitrary `ALTER TABLE`, so the standard pattern is create-new-table + `INSERT INTO ... SELECT` + drop + rename, which copies vectors without re-embedding, the exact same cost class as LanceDB's `add_columns`/`alter_columns`. A schema version lives in the same meta table as the embedding model name.
+- The framework is also the natural vehicle for the store swap itself: on AVX2 hosts, a one-time cross-store migration can read rows out of the existing Lance table and insert them into sqlite-vec with **no re-embedding** (vectors copy as-is). Only non-AVX2 hosts, which today crash outright and therefore have no usable index, need a fresh rebuild.
+
+## Caveats and open questions
+
+- qemu TCG faithfully reproduces CPUID-gated SIGILLs but is not a performance environment; latency numbers are native-host only.
+- Westmere lacks AVX entirely, slightly stricter than the Atom C3758 (Goldmont, SSE4.2) in the issue; SandyBridge covers the AVX-but-no-AVX2 reports. Both fail lancedb, so the conclusion is insensitive to the exact tier.
+- Chroma multi-process and DuckDB locking conclusions come from documentation and upstream issues, not local tests.
+- sqlite-vec: verify `IN` operator support on `vec0` metadata vs partition-key columns during implementation; confirm WAL-mode behavior on the network filesystems some users put `LLM_INDEX_DIR` on (same caveat already applies to SQLite as the main DB).
+- faiss-cpu 1.14.2's missing generic build should be reported to facebookresearch/faiss; if Meta restores variant bundling, faiss still would not beat sqlite-vec here (no metadata, no real deletes).

+# LanceDB Schema Migration Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add a schema versioning and migration system to the LanceDB vector store so that structural column changes can be applied in-place without re-embedding documents, avoiding token costs for users on paid embedding APIs.
+
+**Architecture:** A `schema_version.json` file is written alongside the LanceDB data directory and tracks the current applied version. A `Migration` dataclass registry in `vector_store.py` holds ordered, typed migration steps; each migration is classified as `requires_reembed=True/False`. At index update time, structural-only migrations are applied in-place via LanceDB's `add_columns`/`alter_columns`/`drop_columns` APIs; if any pending migration requires re-embedding, the existing model-mismatch rebuild path is reused.
+
+**Tech Stack:** Python 3.11, lancedb 0.33, pyarrow, pytest, pytest-mock, factory-boy

+- Modify: `src/paperless_ai/vector_store.py`
+- Test: `src/paperless_ai/tests/test_vector_store.py`
+
+- [ ] **Step 1: Write the failing tests**
+
+Add a new class at the bottom of `test_vector_store.py`:

+```
+
+Add `import json` and `import pytest_mock` to the top of `test_vector_store.py`.
+
+- [ ] **Step 2: Run tests to verify they fail**
+
+```bash
+bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_vector_store.py::TestSchemaVersioning -v"
+```
+
+Expected: all 5 tests fail with `ImportError` or `AttributeError` — `CURRENT_SCHEMA_VERSION` and `stored_schema_version` don't exist yet.
+
+- [ ] **Step 3: Implement the schema version helpers in `vector_store.py`**
+
+After the existing imports and before the `DEFAULT_TABLE_NAME` constant, add:
+
+```python
+import json
+from pathlib import Path
+```
+
+After `DEFAULT_TABLE_NAME = "documents"`, add:
+
+```python
+CURRENT_SCHEMA_VERSION: int = 1
+```
+
+After the `ANN_PQ_SUB_VECTORS` constant, add nothing yet — version methods go on the class.
+
+Inside `PaperlessLanceVectorStore`, add these methods after `stored_model_name`:
+
+```python
+@property
+def _schema_version_path(self) -> Path:
+    return Path(self._uri) / "schema_version.json"
+
+def stored_schema_version(self) -> int:
+    """Return the schema version recorded on disk, or CURRENT_SCHEMA_VERSION if missing.
+
+    Missing means either the table predates versioning or was just created and the
+    write hasn't happened yet — treat conservatively as already current.
+    """
+    try:
+        return int(json.loads(self._schema_version_path.read_text())["version"])
+    except (FileNotFoundError, KeyError, ValueError):
+        return CURRENT_SCHEMA_VERSION
+
+def _write_schema_version(self, version: int) -> None:
+    self._schema_version_path.parent.mkdir(parents=True, exist_ok=True)
+    self._schema_version_path.write_text(json.dumps({"version": version}))
+```
+
+Modify `_ensure_table` to write the version after creating the table. Replace the current method body:
+
+```python
+def _ensure_table(self, rows: list[dict[str, Any]], dim: int) -> bool:
+    if self._table is not None:
+        return False
+    self._table = self._conn.create_table(

+        rows,
+        schema=self._schema(dim, self._embed_model_name),
+    )
+    self._write_schema_version(CURRENT_SCHEMA_VERSION)
+    return True
+```
+
+Modify `drop_table` to also remove the version file:
+
+```python
+def drop_table(self) -> None:
+    if self.table_exists():
+        self._conn.drop_table(self._table_name)
+    self._table = None
+    self._schema_version_path.unlink(missing_ok=True)
+```
+
+- [ ] **Step 4: Run tests to verify they pass**
+
+```bash
+bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_vector_store.py::TestSchemaVersioning -v"
+```
+
+Expected: all 5 tests pass.
+
+- [ ] **Step 5: Verify no regressions**
+
+```bash
+bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_vector_store.py -v"
+```
+
+Expected: all existing tests still pass.
+
+- [ ] **Step 6: Lint**
+
+```bash
+ruff check src/paperless_ai/vector_store.py src/paperless_ai/tests/test_vector_store.py
+ruff format src/paperless_ai/vector_store.py src/paperless_ai/tests/test_vector_store.py
+```
+
+Expected: no errors.
+
+- [ ] **Step 7: Commit**
+
+```bash

+(`compare=False, hash=False` excludes `apply` from `__eq__` and `__hash__` — equality is driven by `version` alone, which is the natural identity key. This avoids lambda identity issues in tests and makes the API safe for callers that construct `Migration` instances inline.)

+# Ordered list of schema migrations. Each entry upgrades the table to `version`.
+
+# Structural migrations (requires_reembed=False) are applied in-place via LanceDB's

+
+# To add a migration:

+
+## How to add a migration (reference for future developers)
+
+When a future schema change is needed:
+
+1. Increment `CURRENT_SCHEMA_VERSION` in `vector_store.py`.
+2. Append a `Migration` to `MIGRATIONS` with the new version number.
+3. If the change is **structural only** (add/rename/drop a column, no embedding content changed):
+   - Set `requires_reembed=False`
+   - In `apply`, call `table.add_columns({"col": "CAST(NULL AS string)"})`, `table.drop_columns(["col"])`, or `table.alter_columns({"path": "col", "rename": "new_name"})` as appropriate.
+4. If the change affects **what text gets embedded** (new fields in `build_llm_index_text`, chunk size change baked into schema, etc.):
+   - Set `requires_reembed=True`
+   - `apply` can be a no-op (`lambda t: None`) — the framework will trigger a full rebuild.
+5. Write tests for the migration in `test_vector_store.py` following the `TestApplyStructuralMigrations` patterns.
+
+Example structural migration adding a `language` column:
+
+```python
+CURRENT_SCHEMA_VERSION: int = 2
+
+MIGRATIONS: list[Migration] = [
+    Migration(
+        version=2,
+        description="Add language column for future locale-aware filtering",
+        requires_reembed=False,
+        apply=lambda table: table.add_columns({"language": "CAST(NULL AS string)"}),
+    ),
+]
+```

+# Node Metadata Enrichment Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Move `filename`, `storage_path`, and `archive_serial_number` from the LanceDB embedding text into `node.metadata`, and register a schema migration that triggers an automatic index rebuild on upgrade.
+
+**Architecture:** Three small, independent changes to two source files, tested first. The migration is a no-op `apply` (the rebuild regenerates all nodes with correct metadata). All three tests go red first, then each implementation makes them green.
+
+**Tech Stack:** pytest, pytest-django, pytest-mock, factory_boy, llama_index `MetadataMode`, `feature-lancedb-schema-migrate` branch (must be the base branch for this work).
+
+**Branch base:** `feature-lancedb-schema-migrate`

+
+### Task 1: Fail — embedding text no longer contains the three fields
+
+**Files:**
+
+- Modify: `src/paperless_ai/tests/test_embedding.py`
+
+- [ ] **Step 1: Update `mock_document` fixture to set an explicit `storage_path`**
+
+  The fixture currently doesn't set `storage_path`, so the existing code path (`doc.storage_path.name if doc.storage_path else ''`) would call `.name` on a `MagicMock`. Give it an explicit value so assertions are unambiguous.
+
+  Add these two lines to the `mock_document` fixture after `doc.archive_serial_number = "12345"`:
+
+  ```python
+  doc.storage_path = MagicMock()
+  doc.storage_path.name = "Finance/Bills"
+  ```
+
+- [ ] **Step 2: Update `test_build_llm_index_text` — flip and add assertions**
+
+  The existing test asserts these fields ARE in the result. Change them to assert they are NOT, and add the two missing ones:
+
+  ```python
+  # was: assert "Filename: test_file.pdf" in result
+  assert "Filename: test_file.pdf" not in result
+  assert "Storage Path: Finance/Bills" not in result
+  assert "Archive Serial Number: 12345" not in result
+  ```
+
+  The assertions for `Notes`, `Content`, and `Custom Field` lines are unchanged — leave them as-is.
+
+- [ ] **Step 3: Run the test to confirm it fails**
+
+  ```

+- Modify: `src/paperless_ai/tests/test_ai_indexing.py`
+
+- [ ] **Step 1: Extend `test_build_document_node_structured_fields_in_metadata`**
+
+  This test already checks for `title`, `tags`, etc. Add the three new keys. The `real_document` fixture creates a document with no storage path set, so `storage_path` will be `None` — the key must still be present.
+
+  Replace the existing test body:
+
+  ```python
+  @pytest.mark.django_db
+  def test_build_document_node_structured_fields_in_metadata(
+      real_document: Document,
+  ) -> None:
+      """Structured fields must be in node.metadata so the LLM receives them via metadata prepend."""
+      nodes = indexing.build_document_node(real_document)

+          assert "filename" in node.metadata
+          assert "storage_path" in node.metadata        # None is fine; key must exist
+          assert "archive_serial_number" in node.metadata
+  ```
+
+- [ ] **Step 2: Add a test that storage_path carries the name when set**
+
+  Add a new test function after `test_build_document_node_structured_fields_in_metadata`:
+
+  ```python
+  @pytest.mark.django_db
+  def test_build_document_node_storage_path_name_in_metadata() -> None:
+      """storage_path metadata value is the StoragePath name, not None, when set."""
+      from documents.tests.factories import DocumentFactory, StoragePathFactory
+
+      sp = StoragePathFactory(name="Finance/Bills")
+      doc = DocumentFactory(storage_path=sp)
+
+      nodes = indexing.build_document_node(doc)
+
+      assert len(nodes) > 0
+      for node in nodes:
+          assert node.metadata["storage_path"] == "Finance/Bills"
+  ```
+
+- [ ] **Step 3: Add a test that all three new fields are in `excluded_embed_metadata_keys`**
+
+  Add after the previous test:
+
+  ```python
+  @pytest.mark.django_db
+  def test_build_document_node_new_fields_excluded_from_embedding(
+      real_document: Document,
+  ) -> None:
+      """filename, storage_path, and archive_serial_number must not appear in embedding text."""
+      from llama_index.core.schema import MetadataMode
+
+      nodes = indexing.build_document_node(real_document)
+      assert len(nodes) > 0
+      for node in nodes:
+          assert "filename" in node.excluded_embed_metadata_keys
+          assert "storage_path" in node.excluded_embed_metadata_keys
+          assert "archive_serial_number" in node.excluded_embed_metadata_keys
+          embed_text = node.get_content(metadata_mode=MetadataMode.EMBED)

+### Task 4: Pass — add the three fields to `build_document_node`
+
+**Files:**
+
+- Modify: `src/paperless_ai/indexing.py`
+
+- [ ] **Step 1: Update the `metadata` dict in `build_document_node`**
+
+  Current metadata dict starts at line 106. Replace it:
+
+  ```python
+  metadata = {
+      "document_id": str(document.id),
+      "title": document.title,
+      "filename": document.filename or "",
+      "storage_path": document.storage_path.name if document.storage_path else None,

+      "added": document.added.isoformat() if document.added else None,
+      "modified": document.modified.isoformat(),
+  }
+  ```
+
+- [ ] **Step 2: Update `excluded_embed_metadata_keys`**
+
+  The `LlamaDocument(...)` call currently has:
+
+  ```python
+  excluded_embed_metadata_keys=list(metadata.keys()),
+  ```
+
+  This already excludes all keys, so no change needed here — the new keys are automatically included since they're in the dict. Verify `excluded_llm_metadata_keys` still only excludes `"document_id"`:
+
+  ```python
+  excluded_llm_metadata_keys=["document_id"],
+  ```
+
+  No change needed.
+

+- ✅ Migration v2 registered with `requires_reembed=True` and no-op apply (Tasks 5–6)
+- ✅ `update_llm_index` triggers rebuild on stale schema (Task 7)
+- ✅ Tests: `test_embedding.py`, `test_ai_indexing.py`, `test_vector_store.py`
+
+**Placeholder scan:** None found. Every step has exact code or exact commands.
+
+**Type consistency:**
+
+- `metadata` dict key names (`"filename"`, `"storage_path"`, `"archive_serial_number"`) used consistently across Tasks 1–4.
+- `CURRENT_SCHEMA_VERSION = 2` and `MIGRATIONS[0].version == 2` are consistent across Tasks 5–6.
+- `_store_at_version` and `_node` helpers referenced in Task 5 are defined in the existing `test_vector_store.py` on the `feature-lancedb-schema-migrate` branch.

+# Unicode NFC Normalization for Filesystem Paths Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Ensure all filesystem paths stored in the database and written to disk use NFC Unicode normalization, preventing "file not found" failures caused by byte-level mismatches between visually identical filenames (e.g., NFD `ü` = `u + combining diaeresis` vs NFC `ü` = single codepoint U+00FC).
+
+**Architecture:** The fix has two layers. The primary fix normalizes the output of `clean_filepath()` in `FilePathTemplate.render()` — this is the single choke point through which all template-rendered filenames pass. Defense-in-depth changes normalize input strings before `pathvalidate.sanitize_filename()` in the context builder functions. A separate fix normalizes mail attachment filenames at the entry point. Existing documents with NFD paths will be transparently migrated to NFC on their next save (the file move logic already handles the case where old and new paths differ).
+
+**Tech Stack:** Python `unicodedata.normalize('NFC', ...)`, `pathvalidate`, Django, Jinja2, pytest
+
+---
+
+## Background: The Bug
+
+`pathvalidate.sanitize_filename()` removes illegal filesystem characters but does **not** normalize Unicode. NFC `ü` (UTF-8: `c3 bc`) and NFD `ü` (UTF-8: `75 cc 88`) are visually identical but produce different byte sequences. On Linux filesystems with no normalization (default ZFS, ext4), these are treated as distinct filenames. If an LLM or OCR engine produces NFD text for a document title, the generated filesystem path contains NFD bytes. If the same title is later regenerated in NFC form (LLM output is non-deterministic), the path lookup fails: `old_source_path.is_file()` returns `False` even though a file with the same visual name exists on disk.

+## Task 1: Normalize `clean_filepath()` output (primary fix)
+
+This is the single choke point. ALL template-rendered paths pass through `clean_filepath()` before being stored in `document.filename`. Fixing this alone prevents the bug for every path generated via the filename format system — including `{{ title }}` (sanitized context), `{{ document.title }}` (raw context), `{{ correspondent }}`, and every other template variable.

+
+## Task 2: Defense-in-depth normalization in context builders
+
+`clean_filepath()` (Task 1) fixes the rendered path. These changes normalize the input strings that go into `pathvalidate.sanitize_filename()` within the context builders — belt-and-suspenders so the sanitized shorthand variables (`{{ title }}`, `{{ correspondent }}`, `{{ tag_list }}`, `{{ custom_fields }}`) are also NFC before sanitization. This matters because the sanitized strings could theoretically be compared directly against DB-stored values in other contexts.
+
+**Files:**
+
+- Modify: `src/documents/templating/filepath.py:171-319`
+- Test: `src/documents/tests/test_file_handling.py`
+
+- [ ] **Step 1: Write failing tests**
+
+Add these tests to `TestFileHandling` in `src/documents/tests/test_file_handling.py`:
+
+```python
+@override_settings(FILENAME_FORMAT="{{ tag_list }}/{{ title }}")
+def test_generate_filename_nfc_normalizes_nfd_tag_list(self) -> None:
+    """NFD tag names must produce NFC path component in tag_list."""
+    nfd_name = unicodedata.normalize("NFD", "Büro")
+    nfc_name = unicodedata.normalize("NFC", "Büro")
+
+    doc = Document.objects.create(title="doc", mime_type="application/pdf")
+    doc.tags.create(name=nfd_name)
+    result = generate_filename(doc)
+
+    assert str(result) == f"{nfc_name}/doc.pdf"
+    assert str(result).encode() == f"{nfc_name}/doc.pdf".encode()
+```
+
+- [ ] **Step 2: Run test to verify it fails**
+
+```bash
+uv run pytest --override-ini="addopts=" src/documents/tests/test_file_handling.py::TestFileHandling::test_generate_filename_nfc_normalizes_nfd_tag_list -v
+```
+
+Expected: FAIL. (The tag_list is already caught by `clean_filepath()` from Task 1, but we want a test that directly validates input normalization through the sanitize call.)
+
+Note: this test may already pass after Task 1 due to `clean_filepath()`. If so, keep the test as a regression guard and move straight to the implementation.
+
+- [ ] **Step 3: Normalize inputs in `get_basic_metadata_context()`**
+
+In `src/documents/templating/filepath.py`, update `get_basic_metadata_context()`. The `unicodedata` import was added in Task 1.
+
+```python
+def get_basic_metadata_context(
+    document: Document,
+    *,
+    no_value_default: str = NO_VALUE_PLACEHOLDER,
+) -> dict[str, str]:
+    """
+    Given a Document, constructs some basic information about it.  If certain values are not set,
+    they will be replaced with the no_value_default.
+
+    Regardless of set or not, the values will be sanitized
+    """
+    return {
+        "title": pathvalidate.sanitize_filename(
+            unicodedata.normalize("NFC", document.title),
+            replacement_text="-",
+        ),
+        "correspondent": pathvalidate.sanitize_filename(
+            unicodedata.normalize("NFC", document.correspondent.name),
+            replacement_text="-",
+        )
+        if document.correspondent
+        else no_value_default,
+        "document_type": pathvalidate.sanitize_filename(
+            unicodedata.normalize("NFC", document.document_type.name),
+            replacement_text="-",
+        )

+        else no_value_default,
+        "original_name": PurePath(document.original_filename).with_suffix("").name
+        if document.original_filename
+        else no_value_default,
+        "doc_pk": f"{document.pk:07}",
+    }
+```
+
+- [ ] **Step 4: Normalize inputs in `get_tags_context()`**
+
+Update `get_tags_context()` in the same file:
+
+```python
+def get_tags_context(tags: Iterable[Tag]) -> dict[str, str | list[str]]:
+    """
+    Given an Iterable of tags, constructs some context from them for usage
+    """
+    return {
+        "tag_list": pathvalidate.sanitize_filename(
+            ",".join(
+                sorted(unicodedata.normalize("NFC", tag.name) for tag in tags),
+            ),
+            replacement_text="-",
+        ),
+        # Assumed to be ordered, but a template could loop through to find what they want
+        "tag_name_list": [unicodedata.normalize("NFC", x.name) for x in tags],
+    }
+```
+
+- [ ] **Step 5: Normalize string-type inputs in `get_custom_fields_context()`**
+
+Update `get_custom_fields_context()` in the same file. Only string-type fields (MONETARY, STRING, URL, LONG_TEXT, SELECT) go through `sanitize_filename()`; the others (dates, numbers, booleans) cannot contain non-ASCII unicode. Also normalize the field name itself.
+
+```python
+def get_custom_fields_context(
+    custom_fields: Iterable[CustomFieldInstance],
+) -> dict[str, dict[str, dict[str, str]]]:
+    """
+    Given an Iterable of CustomFieldInstance, builds a dictionary mapping the field name

+## Task 3: Normalize mail attachment filenames
+
+Email attachment filenames come from MIME headers and can be in any Unicode normalization depending on the sending client. These flow into `document.original_filename` and then into `{{ original_name }}` template context. They also become the temp file name created on disk.
+
+**Files:**
+
+- Modify: `src/paperless_mail/mail.py`
+- Test: `src/paperless_mail/tests/test_mail.py`
+
+- [ ] **Step 1: Find the exact lines in mail.py**
+
+```bash
+grep -n "sanitize_filename" src/paperless_mail/mail.py
+```
+
+Expected output (line numbers may vary):
+
+```
+NNN:                attachment_name = pathvalidate.sanitize_filename(att.filename)
+NNN:                    filename=pathvalidate.sanitize_filename(att.filename),
+NNN:            filename=pathvalidate.sanitize_filename(f"{message.subject}.eml"),
+```
+
+Note the line numbers for the next step.
+
+- [ ] **Step 2: Write a failing test**
+
+Find an existing test in `src/paperless_mail/tests/test_mail.py` that exercises attachment filename handling (search for `sanitize_filename` or `att.filename` in that file to find a good base test to copy). Add a new test that uses an NFD attachment filename.
+
+The following test goes into the appropriate `TestCase` class in `src/paperless_mail/tests/test_mail.py`. Look at the file first to confirm the right class and mock patterns — the test below follows the existing pattern for mocking `MailMessage` and `Attachment` objects:
+
+```python
+def test_attachment_filename_nfd_normalized_to_nfc(self) -> None:
+    """Mail attachment filenames with NFD encoding must be normalized to NFC."""
+    import unicodedata
+    nfd_name = unicodedata.normalize("NFD", "Rechnung März.pdf")
+    nfc_name = unicodedata.normalize("NFC", "Rechnung März.pdf")
+    assert nfd_name != nfc_name  # confirm inputs differ at byte level
+
+    # Use whatever mock/factory pattern exists in this test file for creating
+    # a fake attachment with a specific filename, then run the mail handler,
+    # and assert that document.original_filename == nfc_name (not nfd_name).
+    # Adapt the mock setup to match the test file's existing patterns exactly.
+```
+
+To find the right mock pattern: `grep -n "att.filename\|Attachment\|MailMessage\|MagicMock" src/paperless_mail/tests/test_mail.py | head -20`
+
+- [ ] **Step 3: Run the test to verify it fails**
+
+```bash
+uv run pytest --override-ini="addopts=" src/paperless_mail/tests/test_mail.py -k "test_attachment_filename_nfd" -v
+```
+
+Expected: FAIL.
+
+- [ ] **Step 4: Add `import unicodedata` to mail.py**
+
+At the top of `src/paperless_mail/mail.py`, add:
+
+```python
+import unicodedata
+```
+
+- [ ] **Step 5: Normalize attachment filenames in mail.py**
+
+At each of the three `pathvalidate.sanitize_filename` call sites found in Step 1, wrap the input string with `unicodedata.normalize("NFC", ...)`:
+
+For the attachment temp file creation:
+
+```python
+attachment_name = pathvalidate.sanitize_filename(
+    unicodedata.normalize("NFC", att.filename)
+)
+```
+
+For the metadata override filename:
+
+```python
+filename=pathvalidate.sanitize_filename(
+    unicodedata.normalize("NFC", att.filename)
+),
+```
+
+For the EML subject filename:
+
+```python
+filename=pathvalidate.sanitize_filename(
+    unicodedata.normalize("NFC", f"{message.subject}.eml")
+),
+```
+
+- [ ] **Step 6: Run the mail test suite**
+
+```bash
+uv run pytest --override-ini="addopts=" src/paperless_mail/tests/test_mail.py -v
+```
+
+Expected: all tests pass, including the new NFD normalization test.
+
+- [ ] **Step 7: Commit**
+
+```bash
+git add src/paperless_mail/mail.py src/paperless_mail/tests/test_mail.py
+git commit -m "Fix: normalize mail attachment filenames to NFC Unicode"

+
+### Notes for implementer
+
+- The `FILENAME_FORMAT` setting accepts old-style `{title}` format strings, which `convert_format_str_to_template_format()` converts to Jinja2 `{{ title }}` before rendering. Tests using `@override_settings(FILENAME_FORMAT="{{ title }}")` use Jinja2 syntax directly.
+- Run tests with `--override-ini="addopts="` to disable coverage and parallelism for faster iteration.
+- The `unicodedata` module is part of the Python standard library — no new dependency.
+- NFC is the right normalization form for filenames: it is the default on macOS (HFS+/APFS) and the form most databases and text processing tools produce. NFD is what macOS HFS+ _internally_ normalizes to when writing (but presents as NFC), and what some OCR/LLM outputs occasionally produce.

+# LanceDB Node Metadata Enrichment
+
+**Status:** Design
+**Date:** 2026-06-09
+**Branch target:** `dev`
+**Prerequisite for:** AI taxonomy hints (`2026-05-20-ai-taxonomy-hints-design.md`)
+**Depends on:** `feature-lancedb-schema-migrate`
+
+## Problem
+
+`build_llm_index_text` currently includes three short structured values in the embedding text:
+
+```python
+lines = [
+    f"Filename: {doc.filename}",
+    f"Storage Path: {doc.storage_path.name if doc.storage_path else ''}",
+    f"Archive Serial Number: {doc.archive_serial_number or ''}",
+    ...
+]
+```
+
+These don't belong in the embedding. The embedding should capture semantic content — the meaning of the document — not structured identifiers. Including them means vectors are partly "polluted" with filing metadata, making similarity search less accurate. The existing TODO in `embedding.py:115` explicitly calls this out.
+
+The right home for structured values is `node.metadata` (excluded from the embedding, but surfaced to the LLM when nodes are retrieved as context). `title`, `tags`, `correspondent`, and `document_type` already follow this pattern.
+
+Notes and custom fields stay in the embedding text — Notes is long free text, custom fields are dynamic and their semantic content belongs in the vector.
+
+## Changes
+
+### `paperless_ai/embedding.py` — `build_llm_index_text`
+
+Remove the three lines and the TODO comment:
+
+```python
+# remove:
+f"Filename: {doc.filename}",
+f"Storage Path: {doc.storage_path.name if doc.storage_path else ''}",
+f"Archive Serial Number: {doc.archive_serial_number or ''}",
+```
+
+`Notes` and `Custom Fields` lines remain.
+
+### `paperless_ai/indexing.py` — `build_document_node`
+
+Add the three fields to the metadata dict:
+
+```python
+metadata = {
+    "document_id": str(document.id),
+    "title": document.title,
+    "filename": document.filename or "",
+    "storage_path": document.storage_path.name if document.storage_path else None,
+    "archive_serial_number": document.archive_serial_number,
+    "tags": [t.name for t in document.tags.all()],
+    "correspondent": document.correspondent.name if document.correspondent else None,
+    "document_type": document.document_type.name if document.document_type else None,
+    "created": document.created.isoformat() if document.created else None,
+    "added": document.added.isoformat() if document.added else None,
+    "modified": document.modified.isoformat(),
+}
+```
+
+All three new keys must also appear in `excluded_embed_metadata_keys` (consistent with all existing keys — none of the metadata is included in the embedding text).
+
+### `paperless_ai/vector_store.py` — schema migration
+
+Register migration version 2 on the `feature-lancedb-schema-migrate` framework. The embedding text changes, so all existing vectors are stale — a full rebuild is required. The migration's `apply` is a no-op; the rebuild handles regenerating all nodes with the correct metadata.
+
+```python
+MIGRATIONS: list[Migration] = [
+    Migration(
+        version=2,
+        description="move filename/storage_path/asn from embedding text to metadata",
+        requires_reembed=True,
+        apply=lambda table: None,
+    ),
+]
+CURRENT_SCHEMA_VERSION: Final[int] = 2
+```
+
+On next `update_llm_index` run, `requires_reembed_migration()` returns `True`, triggering a full drop-and-rebuild. All new nodes carry the three metadata fields. No manual intervention required.
+
+## Impact
+
+- Similarity search quality improves slightly — vectors are more purely semantic.
+- The LLM receives `filename`, `storage_path`, and `archive_serial_number` as structured metadata alongside retrieved chunks, rather than embedded in the chunk text. Same information, cleaner separation.
+- One forced index rebuild on upgrade (beta: acceptable).
+- `node.metadata["storage_path"]`, `node.metadata["filename"]`, `node.metadata["archive_serial_number"]` are available on all retrieved nodes after rebuild — unblocks the taxonomy hints feature.
+
+## Testing
+
+All tests use pytest style — grouped under classes, `@pytest.mark.django_db` on the class, `pytest-mock`'s `mocker` fixture, every fixture and test signature type-annotated. Format with `ruff` directly.
+
+### `paperless_ai/tests/test_embedding.py` (modify)
+
+- `class TestBuildLlmIndexText:`
+  - Assert `"Filename:"` is **not** in the output.
+  - Assert `"Storage Path:"` is **not** in the output.
+  - Assert `"Archive Serial Number:"` is **not** in the output.
+  - Assert Notes and Custom Fields lines are still present (regression guard).
+
+### `paperless_ai/tests/test_ai_indexing.py` (modify)
+
+- `class TestBuildDocumentNode:`
+  - `filename` is in `node.metadata` and in `excluded_embed_metadata_keys`.
+  - `storage_path` is in `node.metadata` (name string) and in `excluded_embed_metadata_keys`; `None` when document has no storage path.
+  - `archive_serial_number` is in `node.metadata` and in `excluded_embed_metadata_keys`; `None` when unset.
+  - None of the three appear in the embedding text produced for the node.
+
+### `paperless_ai/tests/test_vector_store.py` (modify)
+
+- `class TestSchemaMigrations:`
+  - `pending_migrations()` returns the v2 migration when stored version is 1.
+  - `requires_reembed_migration()` returns `True` when stored version is 1.
+  - `apply_structural_migrations()` stops at the v2 migration (skips reembed entries).

+# LLM Index Schema Migrations (second spec)
+
+Date: 2026-06-10
+Depends on: `docs/superpowers/specs/2026-06-10-sqlite-vec-vector-store-design.md` and its implementation plan (`docs/superpowers/plans/2026-06-10-sqlite-vec-transition.md`). This spec layers on top of the completed sqlite-vec transition; do not start it before that branch lands.
+Supersedes: PR #12968 (in-place LanceDB migrations). The machinery design there is carried over nearly verbatim; only the storage backend specifics change. #12968 should be closed with a pointer here once this ships.
+
+Scope update (user decision, 2026-06-10): the `embedding.py:115` metadata restructure originally drafted as Part 2 of this spec was folded into the transition plan instead (its Task 5), because the transition forces a full rebuild anyway, so the embedded-text change rides along with no extra re-embed cost. This spec is now machinery-only: it ships with an EMPTY migration registry, ready for whatever schema change comes next. Part 2 below is retained as the worked example of how a re-embed migration would be registered, since the next one will not have a free rebuild to piggyback on.
+
+## Part 1: Schema migration machinery (ported from PR #12968)
+
+### What carries over unchanged
+
+The PR's design survives the store swap intact and is adopted as-is:
+
+- `Migration` frozen dataclass: `version: int`, `description: str`, `requires_reembed: bool`, `apply: Callable` (compare/hash-excluded field).
+- `MIGRATIONS: list[Migration]` ordered registry + `CURRENT_SCHEMA_VERSION: Final[int]` in `vector_store.py`. To add a migration: bump the constant, append an entry.
+- Store surface: `stored_schema_version() -> int` (0 when unrecorded, so pre-versioning tables treat every migration as pending), `pending_migrations()`, `requires_reembed_migration()`, `apply_structural_migrations() -> list[Migration]`.
+- The stop-at-first-reembed-boundary rule in `apply_structural_migrations()`: structural migrations are applied in version order only up to the first pending `requires_reembed=True` entry, so the version counter can never jump past a re-embed boundary and silently skip the rebuild. (This was the subtle correctness insight of #12968; preserve the comment.)
+- The `update_llm_index()` hook, verbatim from the PR:
+
+```python
+    with write_store(embed_model_name=model_name) as store:
+        if not rebuild and store.table_exists():
+            store.apply_structural_migrations()
+            if store.requires_reembed_migration():
+                logger.warning(
+                    "Schema migration requires re-embedding; forcing LLM index rebuild.",
+                )
+                rebuild = True
+```
+
+- Test approach from the PR: mock `MIGRATIONS`/`CURRENT_SCHEMA_VERSION` with `mocker.patch`, spy on `drop_table` to distinguish in-place from rebuild, one test per path (structural applied without rebuild; pending re-embed forces rebuild).
+
+### What changes for sqlite-vec
+
+**1. Version storage: `index_meta['schema_version']` instead of `schema_version.json`.**
+The Lance store needed a sidecar JSON file because Lance had no convenient mutable metadata. The sqlite-vec store already has the `index_meta` key/value table, which is transactional with the data itself (a migration and its version bump commit atomically, which the file never could). Concretely:
+
+- `_create_table(dim)` additionally writes `schema_version = str(CURRENT_SCHEMA_VERSION)` (fresh tables are always current).
+- `stored_schema_version()` reads the meta key, returns 0 on absence/garbage.
+- `drop_table()` already does `DELETE FROM index_meta`, which clears the version with it. No sidecar file, no unlink bookkeeping.
+- `apply_structural_migrations()` writes the new version inside the same transaction as the last applied migration.
+
+**2. `apply` receives the store, not a table handle.**
+Lance migrations got the raw table for `add_columns`/`alter_columns`. vec0 virtual tables do not support arbitrary `ALTER TABLE`, so structural migrations are SQL against the store's connection. Signature: `apply: Callable[[PaperlessSqliteVecVectorStore], None]`. The store exposes what migrations need: `.client` (connection), `._table_name`, `.vector_dim()`, and the rebuild helper below.
+
+**3. Structural migrations are create+copy+rename, sharing the compact() machinery.**
+The sqlite-vec `compact()` already implements the only structural mutation vec0 supports: build a new table, `INSERT INTO ... SELECT` (vectors copied bit-for-bit, no re-embedding), drop old, rename. Factor it into a shared helper on the store:
+
+```python
+def rebuild_table(
+    self,
+    *,
+    create_sql: str | None = None,
+    copy_select: str | None = None,
+) -> None:
+    """Copy live rows into a freshly created table and swap it in.
+
+    Defaults reproduce the current schema (compaction). Structural
+    migrations pass a modified CREATE statement and a matching SELECT
+    (e.g. adding a column with a literal default). Runs in one
+    transaction; VACUUM afterwards.
+    """
+```
+
+`compact()` becomes a thin caller (threshold check + `rebuild_table()`), and a structural migration like "add a `+page_count` aux column" is:
+
+```python
+Migration(
+    version=2,
+    description="add page_count auxiliary column",
+    requires_reembed=False,
+    apply=lambda store: store.rebuild_table(
+        create_sql=...,        # CREATE VIRTUAL TABLE ... with the new column
+        copy_select="SELECT id, document_id, modified, node_content, embedding, '' FROM {old}",
+    ),
+)
+```
+
+A pleasant consequence: every structural migration is also a compaction (the copy drops dead rows), and the file-format risk surface is one helper with one test suite instead of two code paths.
+
+**4. Bootstrap version for the sqlite-vec store is 1.**
+The transition plan ships the new store without machinery; tables it creates carry no `schema_version` key and therefore read as 0. This release lands with `CURRENT_SCHEMA_VERSION = 1` and `MIGRATIONS = []`, so the bootstrap is unconditionally safe: a 0-version table has no pending migrations and `apply_structural_migrations()` simply stamps it to 1. (The metadata restructure having moved into the transition itself is what makes this clean; the registry's first real entry will be v2, written against tables that are all stamped.)
+
+## Part 2 (worked example, IMPLEMENTED IN THE TRANSITION): the metadata TODO as a re-embed migration
+
+This section was implemented as Task 5 of the transition plan and ships with the store swap, not with this spec. It is kept as the reference example of how to register the next re-embed migration.
+
+### The change
+
+`build_llm_index_text()` currently embeds three short structured values in the body text:
+
+```python
+        f"Filename: {doc.filename}",
+        f"Storage Path: {doc.storage_path.name if doc.storage_path else ''}",
+        f"Archive Serial Number: {doc.archive_serial_number or ''}",
+```
+
+Per the TODO, move them to `node.metadata` (excluded from embeddings, visible to the LLM via llama-index's metadata prepend), the same treatment title/tags/correspondent/document_type got in PR #12944. Notes and Custom Fields stay in the body (long free text / dynamic count, as the TODO says).
+
+1. `embedding.py build_llm_index_text()`: delete the three lines above (the `lines` list keeps Notes, Custom Fields, and Content). Update the TODO comment to describe only what remains intentional (Notes/Custom Fields stay embedded), or delete it.
+2. `indexing.py build_document_node()` metadata dict gains:
+
+```python
+        "filename": doc.filename,
+        "storage_path": document.storage_path.name if document.storage_path else None,
+        "archive_serial_number": document.archive_serial_number,
+```
+
+(`None`/int values are fine here: this dict lives in the node-content JSON, not in vec0 metadata columns; only `document_id`/`modified` are columns with the NULL restriction. Matches the existing convention of `correspondent: None`.) 3. `excluded_embed_metadata_keys=list(metadata.keys())` already covers the new keys; `excluded_llm_metadata_keys` stays `["document_id"]` so the LLM sees the new fields.
+
+### Why this class of change needs a migration
+
+Removing the three lines changes the embedded text of every document, so stored vectors no longer match what the current code would embed. Incremental updates only re-embed documents whose `modified` changed, so without a forced rebuild the index would be a mixed old/new-text population indefinitely. This particular change escaped that fate only because the transition's forced rebuild covers it. The next embedded-text change will not have that luxury and gets registered like this:
+
+```python
+CURRENT_SCHEMA_VERSION: Final[int] = 2
+
+MIGRATIONS: list[Migration] = [
+    Migration(
+        version=2,
+        description="<what changed about the embedded text>",
+        requires_reembed=True,
+        apply=lambda store: None,
+    ),
+]
+```
+
+On the first `update_llm_index` after upgrade, the hook sees the pending re-embed migration, logs, and rebuilds.
+
+### Test plan
+
+Machinery only (the metadata change is tested in the transition plan's Task 5). Port of the #12968 tests, dedicated file `test_vector_store_migrations.py`: structural migration applies in-place without `drop_table`; pending re-embed forces rebuild; version stamping on create/drop; bootstrap stamping of a pre-machinery 0-version table to 1; stop-at-boundary with a mixed [structural v2, reembed v3, structural v4] registry asserting v4 is NOT applied and the stored version stays at 2; `rebuild_table()` round-trips rows byte-for-byte (shared with compact tests).
+
+### Open questions
+
+- PR #12968 disposition: close with a comment pointing at this spec once the machinery lands (the Lance-specific `add_columns` path has no successor; vec0 cannot do in-place column adds).
+- `created`/`added` fields are also candidates for future structural metadata work, but nothing needs them now (YAGNI; noted only so the next reader does not re-derive it).

+# sqlite-vec Vector Store Design (replaces PaperlessLanceVectorStore)
+
+Date: 2026-06-10
+
+Context: LanceDB wheels SIGILL on non-AVX2 CPUs (#12970); research in `2026-06-10-vector-store-alternatives-research.md` selected sqlite-vec. This is a beta feature, so a one-time re-embed on upgrade is acceptable. Every claim marked [VERIFIED] below was empirically tested against the actual PyPI wheel (0.1.9, and 0.1.10a4 where noted), either in this repo's scratch harness (`/tmp/vstore-avx-test/explore_sqlitevec*.py`) or by the issues-audit agent.
+
+## Version pin: `sqlite-vec==0.1.9`, and why it is load-bearing
+
+- The 0.1.9 linux x86_64 wheel is built with **no SIMD flags at all** (`vec_debug()` shows empty build flags) and passed our qemu Westmere (SSE4.2, no AVX) and SandyBridge (AVX, no AVX2) emulation tests [VERIFIED]. This is the entire point of the migration.
+- The **0.1.10-alpha.4 wheel regresses this**: built with `-mavx -DSQLITE_VEC_ENABLE_AVX` file-wide, no runtime CPU dispatch. It can SIGILL on AVX-less CPUs, including Goldmont Atom/Celeron NAS boxes, exactly the #12970 user base [VERIFIED via vec_debug on the wheel].
+- Guardrails: pin `==0.1.9` exactly; log `SELECT vec_version(), vec_debug()` at store init as an AVX canary; before ever bumping to 0.1.10+, re-check the wheel flags (and consider raising the runtime-dispatch issue upstream first).
+- arm64: 0.1.9 manylinux aarch64 wheel is a proper ELF64 binary, no NEON flags baked [VERIFIED]. (The broken 32-bit "aarch64" wheel era was 0.1.6, fixed since.)
+- No sdist on PyPI (asg017/sqlite-vec#211, open) and no musl wheels; fine for our Debian-based image, blocks Alpine bare-metal installs.
+
+## Schema
+
+One dedicated SQLite database file in `LLM_INDEX_DIR` (e.g. `llmindex.db`), never the Django DB. Connections set `PRAGMA journal_mode=WAL`, `busy_timeout`, `synchronous=NORMAL`.
+
+```sql
+CREATE VIRTUAL TABLE nodes USING vec0(
+    id TEXT PRIMARY KEY,             -- node_id (uuid)
+    document_id TEXT,                -- METADATA column, deliberately NOT a partition key
+    modified TEXT,                   -- ISO timestamp; never NULL (sentinel "")
+    +node_content TEXT,              -- auxiliary column: JSON payload, any size
+    embedding float[{dim}] distance_metric=cosine
+);
+
+CREATE TABLE IF NOT EXISTS index_meta (key TEXT PRIMARY KEY, value TEXT);
+-- rows: embed_model, dim, schema_version, created_by_vec_version
+```
+
+Design decisions, each verified on 0.1.9:
+
+- **`document_id` is a metadata column, not a partition key.** With a partition key, `k` applies per partition: `k=5 AND document_id IN (3 docs)` returns 15 rows (asg017/sqlite-vec#142, open) [VERIFIED]. As a metadata column the same query returns a correct global top-k of exactly 5 [VERIFIED]. `query_similar_documents()` passes permission-scoped `IN` lists, so per-partition semantics would over-fetch k x N(docs). At our scale the partition-pruning speedup is not needed (filtered KNN at 20K x 1024 was _faster_ than unfiltered: 39 ms vs 74 ms).
+- **One document column, not two.** The Lance store carried both `doc_id` (ref_doc_id) and `document_id`; in our usage they are always the same value (`str(document.id)`), so the new schema keeps only `document_id`.
+- **TEXT primary key works** (insert, UPDATE, DELETE, duplicate rejection) [VERIFIED]. There is no usable rowid mapping with a TEXT pk, which we do not need.
+- **Aux column for the payload.** `+node_content` holds the multi-KB JSON; aux columns cannot appear in KNN WHERE clauses (loud error, not silent) [VERIFIED], which we never do, and are selectable in scans and KNN results [VERIFIED].
+- **Metadata columns reject NULL** (asg017/sqlite-vec#141, open) [VERIFIED]. `_row()` must keep coercing everything through `str(... or "")` as it already does today.
+- **`distance_metric=cosine`**: similarity maps as `1 - distance` (identical vector gives distance 0.0 [VERIFIED]). For unit-norm embeddings the ranking equals today's L2 ranking; for non-normalized models cosine is the safer default, and the beta re-embed makes the behavior change free. (L2 + `1/(1+d)` remains available if exact parity is ever wanted.)
+- **Vectors are always bound as float32 BLOBs** (`struct.pack`/`np.tobytes`), never JSON text: bypasses the locale-dependent `strtod` parsing bug (asg017/sqlite-vec#241, open) entirely.
+- Limits, all comfortable: dims <= 8192, k <= 4096, chunk_size default 1024 [VERIFIED]. TEXT metadata has no length cap; values > 12 bytes go to a shadow text table with a prefix fast-path, and the one historical bug at that boundary (long-metadata DELETE, #274) is fixed in 0.1.9.

+
+Filter constraint surface (loud errors otherwise, [VERIFIED]): only `=, !=, <, <=, >, >=, IN` on metadata columns in KNN queries. We use only EQ/IN. Never use `NOT IN` (the vtab cannot see it; SQLite post-filters and silently under-delivers below k, asg017/sqlite-vec#116).
+
+## Compaction: the one real behavioral difference
+
+vec0 DELETE only flips a validity bit; space is never reclaimed, and VACUUM recovers only about half (asg017/sqlite-vec#54, #220, open; fix PRs #243/#210 unmerged). Measured: 5 delete+reinsert cycles on 2K rows grew the file 3.32 MB -> 6.56 MB; VACUUM got back to 4.94 MB. Paperless's per-document churn (every document edit is a delete+reinsert) hits this directly.
+
+So `compact()` becomes the maintainer-endorsed rebuild (asg017/sqlite-vec#205):
+
+```sql
+CREATE VIRTUAL TABLE nodes_new USING vec0(...);
+INSERT INTO nodes_new SELECT id, document_id, modified, node_content, embedding FROM nodes;
+DROP TABLE nodes;
+ALTER TABLE nodes_new RENAME TO nodes;  -- then VACUUM
+```
+
+This copies vectors without re-embedding, runs under the existing write FileLock, and slots into the existing `document_llmindex compact` command and the scheduled maintenance task. A cheap trigger heuristic: rebuild when `count(*) in nodes_rowids shadow` (cumulative) exceeds ~2x live rows, or just keep the existing scheduled cadence.
+
+## Concurrency
+
+vec0 is a plain vtab over ordinary shadow tables, so standard SQLite WAL semantics apply, and the existing architecture is already the textbook arrangement: writers serialized by `settings.LLM_INDEX_LOCK` FileLock, readers concurrent via WAL. Verified across processes: a reader during another process's open write transaction does not block and sees a consistent pre-transaction snapshot; post-commit it sees the new rows [VERIFIED]. No sqlite-vec-specific multi-process corruption, locking, or segfault reports exist in the tracker. The 0.1.10a4 cached-statement fix (#295) is a Firefox/mozStorage `sqlite3_close()` issue; CPython's `sqlite3` is unaffected, no Python-side reports.
+
+Same caveat as the main SQLite DB: `LLM_INDEX_DIR` should not be on NFS.
+
+## Performance expectations (measured on the 0.1.9 no-SIMD wheel)
+
+- KNN 20K rows x 1024 dims: ~74 ms plain, ~39 ms with a metadata EQ filter.
+- 100K x 768: 185 ms/query (vs 497 ms for LanceDB exact search on identical data).
+- Extrapolated 500K x 1024-1536: ~0.9-1.8 s/query; 384 dims roughly 4x faster. Acceptable for suggestions/chat at the extreme tail; typical installs (low tens of thousands of chunks) are tens of ms.
+- Insert: ~3,300 rows/s at 1024 dims in a single transaction.
+- File size: ~raw vector size (~4.3 KB/row at 1024 dims), no compression; plus the bloat behavior above.
+
+## Migration from the Lance store
+
+Beta policy: re-embed. On startup/first index task: if `LLM_INDEX_DIR` contains a Lance table but no `llmindex.db`, log and queue a full rebuild, then remove the Lance directory. No cross-store vector copy, no lancedb import anywhere in the path (which is what un-breaks #12970 hosts: they currently crash at import, have no usable index, and get a fresh build).
+
+PR #12968's migration machinery maps onto `index_meta['schema_version']`: structural migrations = create-new-table + `INSERT ... SELECT` + rename (vectors copied, no re-embed; same shape as the compaction rebuild); re-embed migrations = drop + full rebuild, jumping straight to the current version.
+
+## Dependency changes
+
+- Add: `sqlite-vec==0.1.9` (one ~100 KB platform wheel, zero Python deps).
+- Remove: `lancedb~=0.33.0` (and its pylance/lancedb wheels, ~40 MB). `pyarrow` leaves this module; check whether anything else in the AI stack still needs it before dropping from pyproject.
+
+## Test plan notes
+
+- pytest-style per project convention; the store tests can run against a tmp_path DB file (or `:memory:` for pure-logic tests; extension loading works on uv-managed CPython [VERIFIED]).
+- Port the existing `test_vector_store.py` surface; add dedicated tests for: upsert transactionality (no transient empty state mid-upsert from a second connection), NULL-coercion in `_row()`, k-slice behavior, EQ/IN filter correctness, compaction rebuild preserving rows byte-for-byte, vec_debug canary logging.
+- The qemu matrix (`/tmp/vstore-avx-test/`) can be re-run against any future sqlite-vec bump: `qemu-x86_64 -cpu Westmere venv/bin/python candidate_test.py sqlite_vec <dir>`.
+
+## Benchmark harness
+
+`src/bench_vector_store.py` -- standalone head-to-head comparison run during the migration window when both `PaperlessLanceVectorStore` and `PaperlessSqliteVecVectorStore` coexist (Task 3 Phase A of the implementation plan). After Phase B replaces `vector_store.py`, the Lance import fails gracefully and only the sqlite-vec half runs (useful for post-migration baseline checks).
+
+```bash
+cd src
+uv run python bench_vector_store.py            # auto-generates bench_data.pkl on first run
+uv run python bench_vector_store.py --regenerate  # force re-embed
+```
+
+**Phase 1 (data generation, skipped if `bench_data.pkl` exists):** Faker generates `--n-docs` (default 2000) fake documents -- title, body, correspondent, ISO timestamp. Each body is split into `--chunks-per-doc` (default 3) equal-length chunks (~6000 total nodes). A warm-up embed call fires before generation to ensure the model is resident in GPU. All chunk texts are embedded via Ollama `/api/embed` in batches of 32 and saved to `bench_data.pkl`. Faker seed 42 for reproducibility.
+
+**Phase 2 (benchmark):** Each store runs in an isolated `tempfile.TemporaryDirectory()`. Query vectors are drawn reproducibly from the corpus (every 10th node, wrapping).

+# Agent prompt: add tracking todo for search Phase 2 (Whoosh→Tantivy date queries)
+
+Paste the block below to the paperless-ngx agent. It is self-contained.
+
+---
+
+**Add a tracking todo for search Phase 2 (Whoosh→Tantivy date queries).**
+
+Context discovered while reviewing the upstream `tantivy-py` library against
+`docs/superpowers/specs/2026-06-14-search-query-translation-design.md`:
+
+- §9 of that spec describes an "upstream tantivy-py contribution" needed before Phase 2:
+  making Python `datetime` objects work in `Query.range_query` / `Query.term_query` on
+  `Date` fields.
+- **That contribution is already implemented on `tantivy-py` `master`** — it just postdates
+  the released `0.26.0` wheel the spec was tested against. Two commits close the gap:
+  **#655** (`feat: support unbounded range queries via None bounds`) and **#666**
+  (`fix: add_date loses tzinfo`, which added the `PyDateTime → tantivy DateTime` converter
+  and routed both `range_query` and `term_query` through it). `range_query` with `datetime`
+  (incl. `None` open bounds) and `term_query`/`term_set_query` with `datetime` on `Date`
+  fields were all verified working, and regression tests were added upstream.
+- So the Phase 2 blocker is **no longer a code contribution** — it is simply **a released
+  `tantivy-py` version newer than the current `0.26.0` wheel that includes #655 + #666**,
+  plus the dependency bump on our side.
+
+Please create a tracking todo (in whatever issue/todo system this repo uses) capturing:
+
+1. **Title:** "Unblock search Phase 2: bump tantivy-py once a release includes datetime query
+   support (#655 + #666)."
+2. **Trigger:** A `tantivy-py` release > the current `0.26.0` wheel containing both commits is
+   published to PyPI.
+3. **Action when unblocked:** Bump the `tantivy-py` pin, then execute Phase 2 from the design
+   doc — replace Phase 1's string-sentinel open bounds (`0001-01-01…Z` / `9999-12-31…Z`) and
+   degenerate no-match ranges with real `tantivy.Query` objects (`range_query(..., None)` for
+   open bounds, `empty_query()` for no-match).
+4. **Doc update:** Note in §8/§9 of
+   `docs/superpowers/specs/2026-06-14-search-query-translation-design.md` that the upstream
+   code already exists on master and only a release + bump remains.
+
+Do not start Phase 2 implementation now — this is only a tracking todo. Confirm the current
+pinned `tantivy-py` version in our dependency files when writing it.

+# Design: Whoosh→Tantivy Advanced-Query Translation Layer
+
+**Date:** 2026-06-14
+**Status:** Phase 1 implemented on branch `fix/search-query-translation` (string-pipeline translation layer in `_translate.py`/`_dates.py`, wired into `parse_user_query`). Phase 2 (Query objects) remains gated on the tantivy-py release noted in §8/§9. Plan: `docs/superpowers/plans/2026-06-14-search-query-translation.md`.
+**Branch context:** `beta`. Search code: `src/documents/search/`.
+**Related:** `SEARCH_TANTIVY_WHOOSH_COMPAT.md` (repo root) — full empirical gap matrix and reproduction harnesses. Open branch `fix/scope-comma-expansion` (commit `d8fa97232`) — partial comma fix this design subsumes.
+
+---
+
+## 1. Problem
+
+Paperless migrated full-text search from Whoosh (v2) to Tantivy (v3, commit `aed9abe48`, #12471). A
+compatibility layer in `_query.py` rewrites old Whoosh query syntax into Tantivy syntax via a stack of
+ordered regex substitutions before calling `tantivy.Index.parse_query`.
+
+That regex stack is piecemeal and has hit its complexity ceiling:
+
+- **No structural awareness.** It runs regex on a flat string, so it cannot distinguish a comma inside
+  `[...]` from a top-level clause separator, or know whether a `:` is a field prefix or text. This causes
+  real bugs (e.g. `title:x,created:[2020 TO 2021]` rewrites to malformed `title:x AND title:created:[...]`).
+- **Order-dependence.** Six rewriters with implicit ordering contracts (14-digit before 8-digit, year-range
+  before 8-digit, etc.). Each new date form means reasoning about all interactions again.
+
+The result is a class of v2-valid queries that now return **HTTP 400**. There is no fallback: any syntax
+Tantivy rejects raises out of `parse_query`, propagates through `_backend.py` (no try/except), and is caught
+by the generic handler in `views.py:2471-2475` → `HttpResponseBadRequest`, with the real error only in logs.

+
+## 2. Goals / Non-goals
+
+**Goals**
+
+- Eliminate the date- and comma-class 400s by translating those forms to valid Tantivy syntax.
+- Replace the order-dependent regex stack with a structural, context-aware pass.
+- Match empirically-verified Whoosh v2 semantics (see §3).
+- Additive tests: existing suite stays green during transition.
+- **Field-name aliasing for the four renamed Whoosh→Tantivy fields** (added to scope 2026-06-14):
+  `type`→`document_type`, `type_id`→`document_type_id`, `path`→`storage_path`, `path_id`→`storage_path_id`.
+  These are the only fields the Tantivy migration renamed; v2 queries using the old names currently 400.
+  Both old and new spellings work after aliasing (new names pass through verbatim). The alias targets are the
+  text "name" fields (`document_type` is populated from `document_type.name`), so `type:invoice` →
+  `document_type:invoice` is correct. Fields with no Tantivy equivalent (`owner`, the `has_*` booleans,
+  `is_shared`, `custom_field_count`, `custom_fields_id`) are NOT aliased and remain out of scope.
+
+**Non-goals (explicitly out of scope)**
+
+- Full Whoosh query-language parity.
+- Other Whoosh divergences: unknown-field-degrades-to-text (`http://x/a,b` → 400 on the `http:` unknown
+  field), tolerant unbalanced parens, case-insensitive `AND/OR/NOT`. These pass through to Tantivy unchanged
+  and are recorded as separate, known gaps (§10).
+- `>`/`<`/`>=`/`<=` comparison operators — never supported in paperless-Whoosh (no `GtLtPlugin`); adding them
+  would be a new feature, not a compat fix.
+
+---
+
+## 3. Empirical ground truth (verified, not inferred)
+
+Both engines were run directly; do not regress these without re-checking.
+
+**Whoosh v2** (paperless's exact `MultifieldParser([...]) + DateParserPlugin(basedate=...)` setup):
+
+- `created:2020` → `DateRange(2020-01-01 .. 2020-12-31 23:59:59)`; `created:202003` → March 2020.
+- `created:202023` (month 23) → `<_NullQuery>` — **invalid dates match nothing, never error.**
+- `created:[202001 TO 202006]` → floor/ceil partial-date bounds; `[2020 to]` / `[to 2020]` → open bounds.
+- `created:-1week` → an exact-microsecond `Term` — parsed but matches ~nothing (useless in v2).
+- Comma = AND between clauses, both preserved: `created:[r],added:[r]`, `correspondent:acme,created:[...]`,
+  `invoice,created:2020`.
+- Comma value-list **only** for `KEYWORD(commas=True)` fields (`tag`, `tag_id`, `viewer_id`):
+  `tag:a,b` → `tag:a AND tag:b`. Text-field commas (`correspondent:foo,bar`, `title:10,20`) are split by the
+  field **analyzer** at parse time, not the comma plugin.
+- `title:x,created:[...]` → only the DateRange (Whoosh drops `title:x`) — a v2 free-mode **bug**; the correct
+  target keeps both sides.
+
+**Tantivy 0.26.0** (`tantivy v0.26.0, index_format v7`):
+
+- Date fields require RFC3339 (`...Z`) literals; rejects bare `2020`, `20200101`, `2020-01-01`, lowercase
+  open ranges.
+- Text-field commas parse fine verbatim (`correspondent:foo,bar`, `title:10,20`, `content:a,b,c`).
+- Boolean/paren/phrase structure parses correctly, so a translated date token can sit anywhere:
+  `created:[...Z TO ...Z] OR foo` and `(created:[...] OR foo)` both parse.
+- String date sentinels `0001-01-01T00:00:00Z` and `9999-12-31T23:59:59Z` both parse on a date field.
+
+---
+
+## 4. Architecture (Approach 1: flat tokenizing scanner + single date translator)
+
+The scanner specializes only the date/comma tokens and treats everything else (operators, parens, phrases,
+words, wildcards) as opaque passthrough. Tantivy keeps doing boolean/grouping/phrase parsing. A `field:value`
+span is locally recognizable regardless of surrounding boolean context, so the scanner needs no understanding
+of `AND/OR/NOT`.
+
+### 4.1 Module layout
+
+New module `src/documents/search/_translate.py` — single source of truth:
+
+```
+translate_query(raw: str, tz) -> str        # top-level: scan → transform → recombine
+  scan(raw) -> list[Token]                   # depth-aware char-walk tokenizer
+  _resolve_commas(tokens) -> list[Token]     # comma → AND / value-list / literal
+  translate_date_value(field, raw, tz) -> str  # shape-dispatch date translator
+```
+
+Date-boundary math (`_date_only_range`, `_datetime_range`, floor/ceil helpers) **moves** from `_query.py`
+into `_translate.py` (or a small shared `_dates.py`) so there is one home. The existing math is reused
+verbatim — not rewritten.
+
+### 4.2 Data flow
+
+```
+parse_user_query(raw, tz)
+  → translate_query(raw, tz)          # NEW pipeline
+  → index.parse_query(translated, DEFAULT_SEARCH_FIELDS, field_boosts=_FIELD_BOOSTS)
+```
+
+### 4.3 Transition (delegate + planned removal)
+
+- `rewrite_natural_date_keywords` and `normalize_query` become thin delegators to `translate_query` (or its
+  sub-steps) so their existing assertions still pass.
+- The plan **explicitly schedules deleting both functions and their string-output tests** once
+  `test_translate.py` covers them. Single source of truth, no lingering dead code.
+
+### 4.4 Safety net
+
+`parse_user_query` wraps `translate_query` in try/except. On any unexpected scanner error it falls back to the
+**raw** query string (today's behavior) and logs a warning. The new layer can never regress below current
+behavior; worst case equals the status quo.
+
+---
+
+## 5. Scanner token model
+
+`scan()` is a single left-to-right char walk tracking **quote state** and **`[]`/`{}` bracket depth**. Token
+kinds:
+
+- **`FieldValue(field, value)`** — `field:value`, value a single bare token (no brackets). Recognized when,
+  outside quotes/brackets, it sees `\w+:` followed by a non-bracket value. Value runs until whitespace, a
+  resolved clause-comma, `)`, or end (may itself be quoted: `correspondent:"A B"`).
+- **`FieldValueList(field, [v1, v2, …])`** — value-list, **only** for `field ∈ {tag, tag_id, viewer_id}`. A
+  `FieldValue` whose value is immediately followed by `,term` runs with **no spaces and no colon** in the
+  continuation terms. The no-colon rule fixes `tag:foo,type:bar` (the `type:bar` is not swallowed).
+- **`FieldRange(field, open, lo, hi, close)`** — `field:[lo TO hi]` / `{…}`. Split on case-insensitive
+  `TO`; `lo`/`hi` may be empty (open). Consumed to the matching close bracket.
+- **`Comma`** — emitted only when a depth-0 comma resolves to a clause separator (see §7).
+- **`Passthrough(raw)`** — everything else, byte-for-byte: operators (`AND OR NOT + -`), parens, bare words,
+  wildcards, phrases/quoted spans, whitespace.
+
+**Key properties**
+
+- `field:value` is recognized at any paren depth but **never inside `[]`/`{}` or quotes** — so
+  `(created:2020 OR foo)` still finds the date token, and commas inside `[2020 TO 2021]` or `"a,b"` are never
+  clause separators.
+- Only date fields (`created`, `modified`, `added`) trigger date translation. Every other `field:value` /
+  `field:range` (`tag:`, `asn:`, unknown fields) and every `Passthrough` is re-emitted verbatim — preserving
+  queries Tantivy already handles.
+- Multi-valued set is exactly `{tag, tag_id, viewer_id}`. `custom_fields` is now a JSON structure in the index
+  (Whoosh smashed it into a comma-keyword field; the JSON path handles it better) and is **not** comma-split.
+
+---
+
+## 6. `translate_date_value` — shape dispatch
+
+One entry point per token type, both emitting `field:[<ISO-Z> TO <ISO-Z>]`. `created` uses date-only
+(UTC-midnight) boundaries; `added`/`modified` use local-tz-midnight→UTC. All boundary math reuses the
+existing tested helpers.
+
+### Scalar value (`FieldValue` on a date field)
+
+| Shape                   | Example                            | Result                                                        | Status      |
+| ----------------------- | ---------------------------------- | ------------------------------------------------------------- | ----------- |
+| Keyword (opt. quoted)   | `created:today`, `"previous week"` | existing keyword ranges                                       | works today |
+| 4-digit `YYYY`          | `created:2020`                     | full-year span, emitted as `[2020-01-01T…Z TO 2021-01-01T…Z]` | NEW         |
+| 6-digit `YYYYMM`        | `created:202003`                   | month span                                                    | NEW         |
+| 8-digit `YYYYMMDD`      | `created:20200101`                 | day span                                                      | works today |
+| 14-digit                | `…120000`                          | exact-second point `[t TO t]`                                 | works today |
+| ISO dashed              | `created:2020-01`, `2020-01-01`    | strip separators → digit-precision span                       | NEW         |
+| Bare relative `-N unit` | `created:-1week`                   | `[t TO t]` instant (effectively no-match, matches v2)         | NEW (P3)    |
+| Invalid / unparsable    | `created:202023`                   | **no-match clause, never 400**                                | NEW         |
+
+### Range (`FieldRange`)
+
+Parse each bound with the same shape parser, then `floor(lo)` / `ceil(hi)`:
+
+- Partial / ISO / 8-digit / 14-digit bounds: `[202001 TO 202006]`, `[2020-01-01 TO 2020-12-31]` — NEW.
+- `now` bound: `[20200101 TO now]` — NEW.
+- Open bound (empty side): `[2020 to]`, `[to 2020]` → sentinel far-past floor / far-future ceil (§8) — NEW.
+- Relative bound: generalize existing `[-N unit to now]` so `-N unit` works on either side.
+- Reversed (`lo>hi`): swap (existing year-range `min/max` + Whoosh `disambiguated` behavior).
+- Bare year range `[2005 to 2009]`: unchanged (works today).
+
+**Boundary convention:** keep the existing "ceil = start of next period, inclusive bracket" (e.g.
+`[2005-01-01 .. 2010-01-01]`) that current tests encode. Do not switch to Whoosh's `23:59:59.999999`; document
+the one-instant boundary difference.
+
+---
+
+## 7. Comma resolution
+
+A depth-0 comma is resolved three ways (this single rule set subsumes both `fix/scope-comma-expansion` and
+the unstaged `]`/`"` fix, and fixes Gap E):
+
+1. **Value-list** — preceding token is a `FieldValue`/`FieldValueList` on `{tag, tag_id, viewer_id}` and the
+   following continuation is a bare, colon-free term → repeat the field: `tag:a,b,c` → `tag:a AND tag:b AND tag:c`.
+2. **Clause separator → `AND`** — fires only at a structured boundary:
+   - (a) the comma is preceded by a closing `]` or `"` (`created:[r],added:[r]`, `correspondent:"A B",created:[r]`), or
+   - (b) the comma is followed by a **known schema** `field:` (`title:foo,created:[r]`, `correspondent:foo,created:[r]`).
+     Requiring a _known_ field for (b) prevents `http://x,…`-style misfires.
+3. **Literal** — anything else (a comma followed by a bare term on a non-multivalue field) stays in place:
+   `correspondent:foo,bar`, `title:10,20`, URLs. Tantivy's analyzer tokenizes these on punctuation, matching
+   Whoosh's analyzer behavior.
+
+---
+
+## 8. Open-range handling & the two phases
+
+**Phase 1 (this work) — string output, no tantivy change.**
+Open bounds use verified string sentinels: lower-open → `0001-01-01T00:00:00Z`, upper-open → `9999-12-31T23:59:59Z`
+(both confirmed to parse on a date field in 0.26.0). No-match (invalid date) uses a degenerate date range
+(exact representation flagged for verification in §11).
+
+**Phase 2 (stretch) — build `tantivy.Query` objects for date clauses.**
+`Query.range_query(..., lower_bound=None/upper_bound=None)` gives true open bounds and `empty_query()` gives a
+real no-match, eliminating all string hacks. **Gated only on a released `tantivy-py` > 0.26.0 that includes
+#655 + #666 — the code already exists on `tantivy-py` `master`, it just postdates the `0.26.0` wheel we pin
+(`pyproject.toml`: `tantivy~=0.26.0`); see §9.** Splicing a Query object into an otherwise-string boolean query
+is non-trivial, so Phase 2 is a separate, later effort; Phase 1 ships independently.
+
+Phase 2 also folds in the deferred Phase-1 cleanup (maintainer decision, 2026-06-15):
+
+- Replace the `NO_MATCH` degenerate-range sentinel with `Query.empty_query()` (this also retires the cosmetic
+  issue that `NO_MATCH` always names the `created` field regardless of the queried field).
+- Replace `OPEN_LO`/`OPEN_HI` string sentinels with `range_query(..., None)` open bounds.
+- Retire the now-dead `_rewrite_*` helpers and the `rewrite_natural_date_keywords`/`normalize_query` delegation
+  shims in `_query.py` (~160 lines left from the Phase-1 transition), and migrate their string-output tests in
+  `test_query.py` (replace the direct `_rewrite_compact_date` test with a `translate_scalar` test).
+
+---
+
+## 9. Upstream tantivy-py contribution (PR-ready detail)
+
+> **STATUS UPDATE (2026-06-14): already implemented upstream on `master`.** The date-value gap below is
+> closed by two merged `tantivy-py` commits that postdate the released `0.26.0` wheel we pin:
+> **#655** (`feat: support unbounded range queries via None bounds`) and **#666** (`fix: add_date loses
+tzinfo`, which added the `PyDateTime → tantivy DateTime` converter and routed both `range_query` and
+> `term_query` through it). `range_query` with `datetime` (incl. `None` open bounds) and
+> `term_query`/`term_set_query` with `datetime` on `Date` fields are verified working upstream with
+> regression tests. **The Phase 2 blocker is therefore no longer a code contribution** — it is only a
+> published `tantivy-py` release > `0.26.0` containing #655 + #666, plus bumping our pin
+> (`pyproject.toml`: `tantivy~=0.26.0`). The PR-ready detail below is retained as the historical record of
+> the gap as observed against `0.26.0`.
+
+**Repo:** `quickwit-oss/tantivy-py`. **Observed version:** `0.26.0` (`tantivy v0.26.0, index_format v7`).
+
+**Gap.** Python `datetime` objects cannot be passed to _any_ Query constructor for a `Date` field. Both
+`Query.range_query` and `Query.term_query` reject them:
+
+```
+Expected DateTime type for field created, got datetime.datetime(2020, 1, 1, 0, 0, tzinfo=datetime.timezone.utc)
+```
+
+Int timestamps (seconds and nanoseconds) are also rejected, and there is no exposed/constructible
+`tantivy.DateTime` (`hasattr(tantivy, "DateTime") is False`). Consequently **all** date querying in paperless
+goes through `parse_query` strings; every object-mode `term_query` in the codebase is on integer fields
+(`id`, `owner_id`, `viewer_id`).
+
+**Context.** PR #655 (merged 2026-04-27) added unbounded (`None`) bounds to `range_query`. That solved open
+_bounds_ but left the date _value_ path unusable from Python, so the open-range feature can't actually be used
+on date fields from Python yet.
+
+**Reproduction** (against installed 0.26.0):
+
+```python
+import tantivy
+from datetime import datetime, UTC
+schema = build_schema()  # any schema with a date field "created"
+dt1, dt2 = datetime(2020,1,1,tzinfo=UTC), datetime(2021,1,1,tzinfo=UTC)
+
+tantivy.Query.range_query(schema, "created", tantivy.FieldType.Date, lower_bound=dt1, upper_bound=dt2)
+# -> ValueError: Expected DateTime type for field created, got datetime.datetime(...)
+
+tantivy.Query.range_query(schema, "created", tantivy.FieldType.Date, lower_bound=dt1, upper_bound=None)
+# -> same error (open bound is fine; the date VALUE is the problem)
+
+tantivy.Query.term_query(schema, "created", dt1)
+# -> same error
+```
+
+**Proposed fix (preferred):** in the Rust binding, when the target field is `Date`, accept a Python
+`datetime` and convert internally to `tantivy::DateTime` (e.g. `DateTime::from_timestamp_nanos(...)`), mirroring
+the conversion the indexing path already performs when adding date values to a document (document add-date
+already accepts `PyDateTime`). This makes `range_query`/`term_query` consistent with indexing. The value-coercion
+lives in the Query-construction value handling (the term/bound extraction in the query bindings, e.g.
+`src/query.rs`); reuse the existing `PyDateTime → tantivy DateTime` converter from the document bindings rather
+than adding a new one. Confirm exact locations against the tantivy-py source at PR time.
+
+**Alternative:** expose a constructible `tantivy.DateTime` (from a Python `datetime` or an epoch-nanos int) and
+accept it in `range_query`/`term_query`. Less ergonomic; only do this if reusing the indexing converter proves
+awkward.
+
+**Validation for the PR:**
+
+- `range_query` on a `Date` field with two `datetime` bounds builds and returns expected hits.
+- `range_query` with one `datetime` bound and one `None` (open) works on a `Date` field.
+- `term_query` on a `Date` field with a `datetime` builds and matches.
+- Round-trip: index a doc with a known date, query it back via both closed and open ranges.
+
+When this lands and we bump tantivy-py to the release containing it, Phase 2 (§8) becomes unblocked.
+
+---
+
+## 10. Out of scope / known separate gaps
+
+- **Unknown-field 400.** `http://example.com/a,b` → `Field does not exist: 'http'`. Tantivy treats `http:` as
+  a field; Whoosh's `remove_unknown=True` degraded unknown fields to text. This is the unknown-field divergence,
+  not a comma or date issue. Recorded, not fixed here.
+- `>`/`<`/`>=`/`<=` comparisons — never supported in paperless-Whoosh.
+- Bare relative scalar (`created:-1week`) is P3: it "worked" in v2 but matched nothing. We only guarantee
+  no-400.
+
+---
+
+## 11. Items to verify during implementation
+
+- Exact RFC3339 **open-bound sentinels** to standardize on (`0001-01-01T00:00:00Z` / `9999-12-31T23:59:59Z`
+  both parse; confirm they also behave in actual searches, not just parsing).
+- The **no-match clause** string representation for a date field (a degenerate/empty range that parses but
+  matches nothing). In Phase 2 this becomes `empty_query()`.
+- ISO-dashed precision handling parity with Whoosh's separator-stripping (`-`, `.`, space).
+- Coordination with `fix/scope-comma-expansion`: either land this after that branch merges and delete its
+  now-redundant regex, or absorb its narrowing directly. Do not ship both comma implementations.
+
+---
+
+## 12. Test plan (additive)
+
+- **`test_translate.py` (new):**
+  - `scan()` token-sequence tests: quotes, brackets, parens, URLs, value-lists, mixed clauses.
+  - `translate_date_value` shape table: every §6 row (scalar + range), all three date fields,
+    UTC/Eastern/Auckland timezones (reuse existing tz test patterns).
+  - comma resolution: value-list (`tag`/`tag_id`/`viewer_id`), clause-sep (after `]`/`"`, before known
+    `field:`), literal (text fields, URLs, `title:10,20`).
+  - `translate_query()` golden cases: the full §3 / report-§5b ground-truth matrix.
+- **Parse-acceptance guardrail (current tests lack this):** for every golden case assert
+  `index.parse_query(translate_query(q))` does not raise, against a real index.
+- **End-to-end:** a `views.py` search test asserting previously-400 v2 queries (`created:2020`,
+  `created:[20200101 TO 20201231]`, `title:x,created:[…]`) now return 200.
+- Existing tests stay green via delegation; on removal of the old functions, migrate any unique assertions
+  into `test_translate.py`.
+
+---
+
+## 13. Verification harnesses (keep for regression / ground-truth regeneration)
+
+**Tantivy side** (does a translated string parse?):
+
+```bash
+cd src && PAPERLESS_SECRET_KEY=x uv run python -c "

+
+**Whoosh side** (what did v2 do? — ground truth):
+
+```bash

+  0.26.0, no upstream dependency. Subsumes `fix/scope-comma-expansion`.
+- **Phase 2 (later, gated on §9 upstream):** build `tantivy.Query` objects for date clauses — true open ranges
+  via `range_query(None)`, real no-match via `empty_query()`, no string sentinels. Requires the tantivy-py
+  date-value contribution and a version bump.

+# Search Error Shapes Follow-up Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace the generic advanced-search HTTP 400 ("Error listing search results, check logs for more detail.") with three specific, user-fixable `SearchQueryError` subclasses (`UnknownFieldError`, `InvalidFieldValueError`, `MalformedQueryError`).
+
+**Architecture:** Two detection layers feeding the _existing_ `except SearchQueryError` handler in `UnifiedSearchViewSet.list` (no view change). (1) A **proactive** numeric-value validator inside `translate_query`'s render pass (`_translate.py`) raises `InvalidFieldValueError` before the query reaches Tantivy. (2) A **backstop** wrapper around `index.parse_query` in `parse_user_query` (`_query.py`) maps residual Tantivy `ValueError` message prefixes (`Field does not exist:`, `Syntax Error:`, `Expected a valid integer:`) into the right subclass, so nothing leaks Rust internals or hits the generic 400.
+
+**Tech Stack:** Python 3.11+, Django, `tantivy` (tantivy-py 0.26.0), `regex`, stdlib `difflib`, pytest + pytest-django. All commands run via `uv run` from `src/`.
+
+**Spec:** `docs/superpowers/specs/2026-06-15-search-error-shapes-followup-design.md` (read it first).
+
+**Reference facts (empirically verified 2026-06-15):**
+
+- Tantivy `index.parse_query` raises `ValueError` with exactly these prefixes: `Field does not exist: '<X>'`, `Syntax Error: <echo>`, `Expected a valid integer: 'ParseIntError { kind: InvalidDigit }'`.
+- `page_count:>5`, `asn:<10`, `page_count:>=5`, `asn:[1 TO 10]`, `tag_id:1,2,3` parse OK (comparison operators produce correct `RangeQuery`).
+- `asn:[1 TO]` / `asn:[TO 10]` are a **Syntax Error** (open numeric ranges unsupported; only open _date_ ranges work via sentinels).
+- `scan()` only tokenizes fields in `KNOWN_FIELDS`; unknown `foobar:hello` stays a `Passthrough` and only fails at `parse_query` -> detected by the backstop, not proactively.
+- `difflib.get_close_matches("corespondent", pool)` -> `["correspondent"]`; `has_tags`/`http`/`12` -> `[]` (bare message).
+- `tantivy.Schema` exposes no field-name list, so the drift guard is parse-based.

+
+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd src && uv run pytest documents/tests/search/test_error_shapes.py --override-ini="addopts=" -v`
+Expected: FAIL with `ImportError: cannot import name 'NUMERIC_FIELDS'` (and the other new names).
+
+- [ ] **Step 3: Write minimal implementation**
+
+In `src/documents/search/_translate.py`, add `import difflib` to the stdlib import group (after line 2, before `from dataclasses import dataclass`):
+
+```python
+import difflib
+```
+
+Then, immediately after the `InvalidDateQuery` class (after line 336), add:
+
+```python
+class UnknownFieldError(SearchQueryError):
+    """Raised when a query scopes on a field name that does not exist."""
+
+    def __init__(self, field: str, suggestion: str | None = None) -> None:
+        self.field = field
+        self.suggestion = suggestion
+        message = f"Unknown search field {field!r}."
+        if suggestion:
+            message += f" Did you mean {suggestion!r}?"
+        super().__init__(message)
+
+
+class InvalidFieldValueError(SearchQueryError):
+    """Raised when a numeric field receives a non-numeric value."""

+    def __init__(self, field: str | None = None, value: str | None = None) -> None:

+        super().__init__(message)
+
+
+class MalformedQueryError(SearchQueryError):
+    """Raised for structural syntax errors (unbalanced quotes/brackets, etc.)."""
+```
+
+Add the field-set constants next to `KNOWN_FIELDS` (after line 92, after the `KNOWN_FIELDS` definition):
+
+```python
+# Numeric (unsigned-int) fields. Values must be integers, optionally prefixed by
+# a comparison operator (>, <, >=, <=). Validated proactively in _render.
+NUMERIC_FIELDS = frozenset(
+    {
+        "asn",
+        "page_count",
+        "num_notes",
+        "correspondent_id",

+        "tag_id",
+        "owner_id",
+        "viewer_id",
+    },
+)
+
+# Canonical user-facing field names for validation and did-you-mean suggestions.
+# Aliases are excluded so a typo is never "corrected" to a deprecated alias.
+SEARCHABLE_FIELDS = KNOWN_FIELDS - frozenset(FIELD_ALIASES)
+```
+
+Note: `SEARCHABLE_FIELDS` references `FIELD_ALIASES`, which is defined above `KNOWN_FIELDS` (line 54), so this ordering is valid.
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd src && uv run pytest documents/tests/search/test_error_shapes.py --override-ini="addopts=" -v`
+Expected: PASS (all `TestErrorClasses` and `TestFieldSets` cases green).

+- [ ] **Step 2: Run test to verify it fails**
+
+Run: `cd src && uv run pytest "documents/tests/search/test_error_shapes.py::TestProactiveNumericValidation" --override-ini="addopts=" -v`

+
+- [ ] **Step 3: Write minimal implementation**
+
+In `src/documents/search/_translate.py`, add a module-level regex near the other operator patterns (after line 510, near `_SPACED_OP_RE`):
+
+```python
+# Leading comparison operator on a numeric value (asn:>5, page_count:<=10).
+_COMPARISON_PREFIX_RE = regex.compile(r"^(>=|<=|>|<)")
+```
+

+
+```python
+def _validate_numeric(field: str, value: str) -> None:
+    """Raise InvalidFieldValueError if a numeric-field value is not an integer.
+
+    Strips a single leading comparison operator (>, <, >=, <=) and surrounding
+    quotes first so comparison queries pass. An empty value (open range bound)
+    is accepted here; an open numeric bracket-range still fails downstream at
+    parse_query as a Syntax Error, surfaced as MalformedQueryError.
+    """
+    candidate = _COMPARISON_PREFIX_RE.sub("", value.strip().strip("\"'")).strip()
+    if candidate == "":
+        return
+    if not candidate.isdigit():
+        raise InvalidFieldValueError(field, value)
+```
+
+Modify `_render` (lines 490-502) to validate numeric fields. Replace the `FieldValueList`, `FieldValue`, and `FieldRange` branches with:
+
+```python
+    if isinstance(tok, FieldValueList):
+        field = FIELD_ALIASES.get(tok.field, tok.field)

+
+Run: `cd src && uv run pytest "documents/tests/search/test_error_shapes.py::TestBackstopViaParseUserQuery" --override-ini="addopts=" -v`
+Expected: FAIL — unknown-field/syntax cases currently raise the bare Tantivy `ValueError`, not the new subclasses (the `index.parse_query` calls are unwrapped). The numeric-mismatch and success cases may already pass.
+
+- [ ] **Step 3: Write minimal implementation**
+
+In `src/documents/search/_query.py`, add the import alongside the existing translate imports (after line 20):
+
+```python
+from documents.search._translate import map_tantivy_error
+```
+
+Add a module-level helper (place it just above `parse_user_query`, before line 191):
+
+```python
+def _parse_query_friendly(
+    index: tantivy.Index,
+    query_str: str,
+    raw_query: str,
+    default_fields: list[str],
+    **kwargs,
+) -> tantivy.Query:
+    """Call index.parse_query, translating Tantivy ValueErrors into user-safe
+    SearchQueryError subclasses. Unrecognised errors are re-raised unchanged."""
+    try:

+    except SearchQueryError:

+    except ValueError as exc:
+        mapped = map_tantivy_error(exc, raw_query)
+        if mapped is not None:
+            raise mapped from exc
+        raise
+```
+
+In `parse_user_query`, replace the exact-query parse (lines 231-235):
+
+```python
+    exact = _parse_query_friendly(
+        index,
+        query_str,
+        raw_query,
+        DEFAULT_SEARCH_FIELDS,
+        field_boosts=_FIELD_BOOSTS,
+    )
+```
+
+and the fuzzy parse (lines 253-259):
+
+```python
+        fuzzy = _parse_query_friendly(
+            index,
+            query_str,
+            raw_query,
+            DEFAULT_SEARCH_FIELDS,
+            field_boosts=_FIELD_BOOSTS,
+            # (prefix=True, distance=1, transposition_cost_one=True) — edit-distance fuzziness
+            fuzzy_fields={f: (True, 1, True) for f in DEFAULT_SEARCH_FIELDS},
+        )
+```
+
+(`SearchQueryError` is already imported in `_query.py` at line 19.)
+
+- [ ] **Step 4: Run test to verify it passes**
+
+Run: `cd src && uv run pytest "documents/tests/search/test_error_shapes.py::TestBackstopViaParseUserQuery" --override-ini="addopts=" -v`
+Expected: PASS.
+
+- [ ] **Step 5: Run the full query test file for regressions**
+
+Run: `cd src && uv run pytest documents/tests/search/test_query.py --override-ini="addopts=" -q`
+Expected: PASS (existing `parse_user_query` behavior, including `InvalidDateQuery` propagation, intact).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/documents/search/_query.py src/documents/tests/search/test_error_shapes.py
+git commit -m "feat(search): wrap parse_query to surface friendly error shapes"

+
+---
+
+### Task 5: Guard tests (pin prefixes + drift) and view-level 400
+
+**Files:**
+
+- Modify: `src/documents/search/__init__.py` (verify the new error classes are exported; add if missing)
+- Test: `src/documents/tests/search/test_error_shapes.py` (pin + drift guards)
+- Test: `src/documents/tests/test_api_search.py` (one view-level integration test)
+
+- [ ] **Step 1: Verify the search package exports the new classes**
+
+Run: `cd src && rg -n "SearchQueryError|InvalidDateQuery|__all__" documents/search/__init__.py`
+
+If `SearchQueryError` is re-exported there (the view imports `from documents.search import SearchQueryError`), add the three new classes the same way. Example edit — add to the existing `from documents.search._translate import ...` block and to `__all__` if present:
+
+```python
+from documents.search._translate import InvalidFieldValueError
+from documents.search._translate import MalformedQueryError
+from documents.search._translate import UnknownFieldError
+```
+
+(The subclasses route through the existing `except SearchQueryError` handler regardless, so exporting is for discoverability/consumers. Skip if the package does not re-export error classes.)
+
+- [ ] **Step 2: Write the failing pin + drift guard tests**
+
+Append to `src/documents/tests/search/test_error_shapes.py`:
+
+```python
+from documents.search._query import DEFAULT_SEARCH_FIELDS
+from documents.search._query import _FIELD_BOOSTS
+from documents.search._translate import SEARCHABLE_FIELDS as _SEARCHABLE
+
+
+@pytest.mark.search

+    """Every user-facing searchable field must be a real schema field. tantivy
+    exposes no field-name list, so we assert via parse: a real field never raises

+    def test_searchable_field_exists_in_schema(self, index: tantivy.Index, field):
+        try:

+            )
+        except ValueError as exc:
+            # A type/syntax error proves the field EXISTS; only "does not exist"
+            # is a drift failure.
+            assert "Field does not exist" not in str(exc), (
+                f"{field!r} is in SEARCHABLE_FIELDS but missing from the schema"
+            )
+```
+
+- [ ] **Step 3: Run the guard tests to verify they pass**
+
+Run: `cd src && uv run pytest "documents/tests/search/test_error_shapes.py::TestTantivyPinnedPrefixes" "documents/tests/search/test_error_shapes.py::TestFieldDriftGuard" --override-ini="addopts=" -v`
+Expected: PASS. (These assert current truth; they guard against future drift. If `TestFieldDriftGuard` fails now, `SEARCHABLE_FIELDS` lists a name not in the schema — fix `KNOWN_FIELDS`/`NUMERIC_FIELDS`, not the test.)
+
+- [ ] **Step 4: Write the failing view-level test**
+
+In `src/documents/tests/test_api_search.py`, locate `test_search_added_invalid_date` (around line 723) and add this test directly after it, inside the same `TestDocumentSearchApi` class (mirrors that test's structure):
+
+```python
+    def test_search_unknown_field_returns_400(self) -> None:
+        """
+        GIVEN:
+            - A query scoping on a non-existent field

+        THEN:
+            - HTTP 400 with the unknown-field message under the "query" key
+        """
+        response = self.client.get("/api/documents/?query=foobar:hello")
+        self.assertEqual(response.status_code, status.HTTP_400_BAD_REQUEST)
+        self.assertIn("foobar", str(response.data["query"]))
+```
+
+- [ ] **Step 5: Run the view-level test to verify it passes**
+
+Run: `cd src && uv run pytest "documents/tests/test_api_search.py::TestDocumentSearchApi::test_search_unknown_field_returns_400" --override-ini="addopts=" -v`
+Expected: PASS (the existing `except SearchQueryError` handler converts `UnknownFieldError` to `ValidationError({"query": [...]})`).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/documents/search/__init__.py src/documents/tests/search/test_error_shapes.py src/documents/tests/test_api_search.py

+- `UnknownFieldError` (+ did-you-mean, legacy backend fields as unknown) -> Tasks 1, 3, 4.
+- `InvalidFieldValueError` (proactive + backstop) -> Tasks 1, 2, 4.
+- `MalformedQueryError` (balance-check, no verbatim echo, open-range caveat) -> Tasks 1, 3, 4.
+- Hybrid detection (proactive scanner + backstop wrapper) -> Tasks 2, 4.
+- `>`/`<` left working + validator allows operators -> Task 2 (`test_valid_numeric_values_do_not_raise`), Task 4 (`test_comparison_and_range_queries_succeed`).

+# Bulk-Edit Operation Registry Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Collapse the bulk-edit operation definition — today smeared across 8 sites in 3 files, keyed 3 different ways — into a single `BulkEditOperation` object per operation, held in an ordered registry. The serializer and both view call sites consume the registry instead of re-encoding the operation list. The wire/API contract is preserved byte-for-byte; per-operation OpenAPI examples are added so the bulk API documents itself.
+
+**Architecture:** A new `documents/bulk_operations.py` defines a `BulkEditOperation` ABC, a frozen `PermissionRequirements` value object, a per-operation DRF parameter serializer (validation + coercion), and an ordered `BULK_EDIT_OPERATIONS` registry whose 16 entries wrap the existing `bulk_edit.py` functions (which are unchanged). `BulkEditSerializer` resolves a method string to an operation and delegates parameter validation; `BulkEditView.post` and `_execute_document_action` read `op.needs_user` / `op.audit_field` / `op.required_permissions(...)` instead of the `METHOD_NAMES_*` sets, `MODIFIED_FIELD_BY_METHOD`, and the three `method in [...]` permission blocks.
+
+**Tech Stack:** Python ≥3.11, Django REST Framework, drf-spectacular, pytest + pytest-mock + factory-boy. Backend tests run on the Linux VM (this is a Windows host); `ruff` runs locally.
+
+**Spec:** `docs/superpowers/specs/2026-06-16-bulk-edit-operation-registry-design.md` (rev. 2 — read the Operation inventory matrix and the Parameter coercion contract before starting; they are the source of truth for every per-op cell).
+
+---
+
+## Conventions for every task
+
+- **Run backend tests on the VM** via the helper (never locally — the lockfile is linux/macOS only):
+  ```bash
+  bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "<pytest targets/args>"
+  ```
+- **Lint locally** with the global ruff binary (not `uv run`):
+  ```bash
+  ruff check src/documents/bulk_operations.py src/documents/serialisers.py src/documents/views.py
+  ruff format src/documents/bulk_operations.py src/documents/serialisers.py src/documents/views.py
+  ```
+- **New tests are pytest-style** (per CLAUDE.md): grouped in classes, `@pytest.mark.django_db` on the class where DB is needed, factory-boy factories (`UserFactory`, `DocumentFactory`, `TagFactory`, …), the `mocker` fixture, `@pytest.mark.parametrize`, full type annotations on fixtures and tests.
+- **`CustomFieldFactory` does not exist yet** in `tests/factories.py` (only `Correspondent`/`DocumentType`/`Tag`/`StoragePath`/`Document`/`User`/`PaperlessTask`). The `modify_custom_fields` `clean_parameters` tests need `CustomField` rows — add a `CustomFieldFactory` there first (per CLAUDE.md's "add a factory when a model lacks one").
+- **Do NOT convert the existing `test_api_bulk_edit.py`** (DRF `APITestCase` style) — it is the regression net and stays as-is. It must be green at every commit. Its `mock.patch("documents.serialisers.bulk_edit.<fn>")` / `documents.views.bulk_edit.<fn>` targets keep working **only if** the two invariants below hold — verify them, do not assume them.
+
+### Two load-bearing invariants (the contract-preservation kernel)
+
+1. **Module identity:** `serialisers.py`, `views.py`, and the new `bulk_operations.py` must each import the operations module as `from documents import bulk_edit` (module import, not `from documents.bulk_edit import merge`). All three then reference the _same_ `sys.modules["documents.bulk_edit"]` object, so a `mock.patch("documents.serialisers.bulk_edit.merge")` mutates the attribute every call site sees. **Verify** `serialisers.py` and `views.py` already use `from documents import bulk_edit` before relying on this.
+2. **Call-time lookup:** each `BulkEditOperation.execute` must call `bulk_edit.merge(doc_ids, **kw)` (attribute lookup at call time), NOT capture the function at class-definition time (`fn = bulk_edit.merge` as a class attribute). Otherwise the patch — applied after import — won't be seen.
+
+## File structure
+
+- **Create** `src/documents/bulk_operations.py` — `PermissionRequirements`, `BulkEditOperation` ABC, the per-op parameter serializers, the 16 operation classes, and the ordered `BULK_EDIT_OPERATIONS` registry. One cohesive module.
+- **Create** `src/documents/tests/test_bulk_operations.py` — pytest-style unit tests: the permission-matrix characterization (Task 1), then `required_permissions` / `clean_parameters` / registry-parity unit tests (Task 2).
+- **Modify** `src/documents/serialisers.py` — rewrite `BulkEditSerializer.method` choices, `validate_method`, and `validate()`; delete the `_validate_parameters_*` methods (their logic moves into the per-op serializers).
+- **Modify** `src/documents/views.py` — rewrite `_has_document_permissions`; delete `METHOD_NAMES_REQUIRING_USER`/`_TRIGGER_SOURCE` and `MODIFIED_FIELD_BY_METHOD`; route `BulkEditView.post` through the registry; change `_execute_document_action`'s signature from `method` to `op`; and update the **six** moved-endpoint caller views (`RotateDocumentsView`, `MergeDocumentsView`, `DeleteDocumentsView`, `ReprocessDocumentsView`, `EditPdfDocumentsView`, `RemovePasswordDocumentsView`, `views.py:2964-3109`) to pass `op=BULK_EDIT_OPERATIONS["<name>"]` instead of `method=bulk_edit.<fn>`. Add `from drf_spectacular.utils import OpenApiExample` (Task 4 needs it — not currently imported).
+
+---
+
+## Task 1: Permission-matrix characterization test (the safety net)
+
+This test freezes today's permission behavior **before** any refactor. It must PASS against the current code unchanged — if any case is red now, the spec's matrix (or your reading of it) is wrong; stop and reconcile before proceeding. After the cutover (Task 3) it must still pass identically.
+
+**Files:**
+
+- Create: `src/documents/tests/test_bulk_operations.py`
+
+- [ ] **Step 1: Write the behavior-level permission test against the live API**
+
+Drive the real `bulk_edit/` endpoint so the test is independent of internal structure (it survives the refactor without edits). Build users with precise permission sets and owners, and assert the 200-vs-403 outcome per operation and parameter combination. Cover, at minimum, the conditional cases the spec calls out:
+
+- ownership required: `set_permissions`, `delete`, `rotate`, `delete_pages`, `edit_pdf`, `remove_password` (unconditional); `merge`/`split` only when `delete_originals=true`.
+- `add_document` required: `split`, `merge` (unconditional); `edit_pdf`/`remove_password` only when `update_document` is falsy.
+- `delete_document` required: `delete` (unconditional); `merge`/`split` only when `delete_originals=true`.

+
+Notes:
+
+- Mock the underlying `bulk_edit.<fn>` (patch `documents.views.bulk_edit.<fn>`) so the operations don't actually run — this test is purely about the permission gate returning 200 vs 403.
+- A superuser short-circuits to allowed (`views.py:2697`); include one superuser row to pin that.
+- This is verbose by design; the matrix is the security contract. Prefer one parametrized test over hand-written methods.
+- **Cover the six moved single-action endpoints too (REQUIRED — C2).** `/api/documents/rotate/`, `/merge/`, `/delete/`, `/reprocess/`, `/edit_pdf/`, `/remove_password/` run the **same** `_has_document_permissions` gate via `_execute_document_action`, and that path is rewritten in Task 3 (C1). Add a parallel parametrized test that POSTs to each (their request bodies are the dedicated serializers' fields — e.g. `{"documents": [...], "degrees": 90}` for rotate — **not** a `method`+`parameters` envelope). The existing `test_api_bulk_edit.py` already covers these endpoints' permission gates (`test_rotate_insufficient_permissions:1320`, `test_merge_and_delete_insufficient_permissions:1381`, `test_edit_pdf_insufficient_permissions:1635`, `test_remove_password_insufficient_permissions:1719`), so this is hardening rather than the sole net — but make the moved-endpoint matrix explicit here so the `_execute_document_action` rewrite is guarded by a parametrized characterization, not scattered one-offs.
+- **`edit_pdf` test docs need a `page_count` (M3).** `clean_parameters` for `edit_pdf` bounds-checks `op["page"]` against `Document.page_count` (`serialisers.py:2052-2059`); this test mocks execution but **not** validation, so an `edit_pdf` row with `page: 1` needs its target doc created with `page_count >= 1`, else it fails with a 400 (out-of-bounds) instead of the expected 200/403.
+
+- [ ] **Step 2: Run it against CURRENT code — it must PASS**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_bulk_operations.py -v"`
+Expected: PASS. If any row is red, the spec matrix is misread — reconcile against `views.py:2713-2760` before writing any production code.

+## Task 2: Build `bulk_operations.py` (registry, ABC, ops, serializers) — old path untouched
+
+Build the entire new module with full unit coverage **while the existing dispatch still runs**, so the whole suite stays green throughout. Nothing in `serialisers.py`/`views.py` changes in this task.
+
+**Files:**

+
+- [ ] **Step 3: Implement `PermissionRequirements` and the `BulkEditOperation` ABC**
+
+```python
+from __future__ import annotations
+
+import dataclasses

+from abc import abstractmethod
+from typing import ClassVar
+
+from rest_framework import serializers

+
+@dataclasses.dataclass(frozen=True)
+class PermissionRequirements:

+            context={"user": user, "documents": documents},
+        )
+        serializer.is_valid(raise_exception=True)
+        # merge coerced/validated values back over the raw dict so passthrough
+        # keys (e.g. metadata_document_id, source_mode) survive.
+        return {**parameters, **serializer.validated_data}
+
+    def required_permissions(self, parameters: dict) -> PermissionRequirements:
+        return PermissionRequirements()
+
+    @abstractmethod
+    def execute(self, doc_ids: list[int], **parameters) -> str: ...
+```
+
+- [ ] **Step 4: Implement the 16 operation classes + parameter serializers**
+
+Follow the spec's Operation inventory matrix for every cell. Representative examples — the simple assignment op, and the two conditional ones:
+
+```python
+class SetCorrespondentOperation(BulkEditOperation):
+    name = "set_correspondent"
+    audit_field = "correspondent"
+    parameter_serializer_class = SetCorrespondentParametersSerializer  # validates correspondent id|null
+    example_parameters = {"correspondent": 1}
+
+    def execute(self, doc_ids, **kw):
+        return bulk_edit.set_correspondent(doc_ids, **kw)
+
+
+class MergeOperation(BulkEditOperation):
+    name = "merge"
+    supports_all = False
+    needs_user = needs_trigger_source = True
+    parameter_serializer_class = MergeParametersSerializer
+    example_parameters = {"delete_originals": False, "archive_fallback": False}
+
+    def required_permissions(self, parameters):
+        delete = parameters.get("delete_originals", False)
+        return PermissionRequirements(
+            change=True, add_document=True,
+            ownership=delete, delete_document=delete,
+        )
+
+    def execute(self, doc_ids, **kw):
+        return bulk_edit.merge(doc_ids, **kw)
+
+
+class EditPdfOperation(BulkEditOperation):
+    name = "edit_pdf"
+    supports_all = False
+    max_documents = 1
+    too_many_documents_message = "Edit PDF method only supports one document"
+    needs_user = needs_trigger_source = True
+    parameter_serializer_class = EditPdfParametersSerializer
+    example_parameters = {"operations": [{"page": 1, "rotate": 90}], "update_document": False, "include_metadata": True}
+
+    def required_permissions(self, parameters):
+        # edit_pdf is ALWAYS ownership-gated (views.py:2722); add_document only
+        # when NOT update_document (views.py:2740-2741).
+        update = parameters.get("update_document", False)
+        return PermissionRequirements(change=True, ownership=True, add_document=not update)
+
+    def execute(self, doc_ids, **kw):
+        return bulk_edit.edit_pdf(doc_ids, **kw)
+```
+
+Parameter serializers carry the validation+coercion the spec's "Parameter coercion contract to preserve" section enumerates — preserve the exact `ValidationError` message strings. Example for the DB/cross-field case:
+
+```python
+class EditPdfParametersSerializer(serializers.Serializer):
+    operations = serializers.ListField(child=serializers.DictField())
+    update_document = serializers.BooleanField(required=False, default=False)
+    include_metadata = serializers.BooleanField(required=False, default=True)
+    # source_mode handled here too, only when present
+
+    def validate(self, attrs):
+        # reproduce serialisers.py:2045-2059 verbatim, incl. messages:
+        #  - "update_document only allowed with a single output document"
+        #  - page-bounds: "Page {n} is out of bounds for document with {k} pages."
+        #    using self.context["documents"][0] / Document.objects.get(...)
+        return attrs
+```
+
+`RemovePasswordOperation` keeps an `update_document` param (it exists — `bulk_edit.py:881`); its `required_permissions` mirrors `EditPdfOperation`'s `add_document=not update` (but ownership is unconditional too — see matrix). `DeleteOperation` / `ReprocessOperation` set `parameter_serializer_class = None`. Do **not** register `redo_ocr`.
+
+**Defaulting parity (H3) — match each old validator exactly, no more, no less.** `test_api_bulk_edit.py` asserts `mock.call_args` kwargs, so a serializer that injects a default the old validator didn't will break those asserts. `edit_pdf` _did_ default `update_document=False` / `include_metadata=True` (`serialisers.py:2038-2043`) → keep them. `remove_password` validated **only** `password` (`serialisers.py:2061-2065`) and did **not** default `update_document` / `include_metadata` / `delete_original` → `RemovePasswordParametersSerializer` must declare only `password`. `update_document` then survives as a **raw passthrough key** in `parameters` (so `required_permissions` still reads it via `parameters.get("update_document", False)`), and no extra kwargs reach `bulk_edit.remove_password`. Apply the same "match the old defaulting" rule to every op.
+
+**`set_permissions` transform (H2) — the QuerySet shape is load-bearing.** `SetPermissionsParametersSerializer` must run `validate_set_permissions` (from `SetPermissionsMixin`, which `BulkEditSerializer` already inherits) so that `validated_data["set_permissions"]` carries the **QuerySet-dict** structure `bulk_edit.set_permissions` consumes — not the raw `{view:{users:[ids]}}` dict. A plain `DictField` would leave the raw dict in `validated_data`, and `{**parameters, **validated_data}` would then feed the function the wrong shape. Also default `merge=False` and validate `owner` existence (`serialisers.py:1946-1952`).
+
+Build the **ordered** registry (legacy section in `MOVED_DOCUMENT_ACTION_ENDPOINTS` key order — `edit_pdf, remove_password` before `split, delete_pages`):
+
+```python
+BULK_EDIT_OPERATIONS: dict[str, BulkEditOperation] = {
+    op.name: op
+    for op in (
+        SetCorrespondentOperation(), SetDocumentTypeOperation(),
+        SetStoragePathOperation(), AddTagOperation(), RemoveTagOperation(),
+        ModifyTagsOperation(), ModifyCustomFieldsOperation(), SetPermissionsOperation(),
+        DeleteOperation(), ReprocessOperation(), RotateOperation(), MergeOperation(),
+        EditPdfOperation(), RemovePasswordOperation(), SplitOperation(), DeletePagesOperation(),
+    )
+}
+```
+
+- [ ] **Step 5: Run unit tests to green**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_bulk_operations.py -v"`
+Expected: PASS (permission matrix, required_permissions, registry parity, clean_parameters). The existing `test_api_bulk_edit.py` is untouched and still green (old path runs).
+
+- [ ] **Step 6: Lint & commit**
+
+```bash
+ruff check src/documents/bulk_operations.py && ruff format src/documents/bulk_operations.py
+git add src/documents/bulk_operations.py src/documents/tests/test_bulk_operations.py
+git commit -m "Feature: add bulk-edit operation registry (not yet wired)"
+```
+
+---
+
+## Task 3: Cutover — wire the serializer and BOTH view call sites
+
+This is the atomic swap: `validate_method` returning an operation object ripples to both view sites, so serializer + views land in **one commit**. The full `test_api_bulk_edit.py` regression suite plus Task 1's matrix test are the contract; both must be green at the end.
+
+**Files:**
+
+- Modify: `src/documents/serialisers.py`
+- Modify: `src/documents/views.py`
+
+- [ ] **Step 1: Confirm invariant #1**
+
+Grep that `serialisers.py` and `views.py` import `from documents import bulk_edit` (not `from documents.bulk_edit import ...`). If they use member imports, the existing patches break — convert to module import as part of this task and note it.
+
+- [ ] **Step 2: Rewrite `BulkEditSerializer`**
+
+- `method = serializers.ChoiceField(choices=list(bulk_operations.BULK_EDIT_OPERATIONS), ...)` — registry alone (16, canonical order), **not** `+ LEGACY_DOCUMENT_ACTION_METHODS`.
+- `validate_method` → `return bulk_operations.BULK_EDIT_OPERATIONS[method]` (returns the op; raise `ValidationError("Unsupported method.")` on KeyError to preserve the message).
+- `validate()`:
+  ```python
+  op = attrs["method"]
+  if attrs.get("all", False) and not op.supports_all:
+      raise serializers.ValidationError("This method does not support all=true.")
+  if op.max_documents is not None and len(attrs["documents"]) > op.max_documents:
+      raise serializers.ValidationError(op.too_many_documents_message)
+  attrs["parameters"] = op.clean_parameters(
+      attrs["parameters"], user=self.user, documents=attrs["documents"],
+  )
+  return attrs
+  ```
+- **Delete** all `_validate_parameters_*` / `_validate_storage_path` / `validate_parameters_remove_password` methods (their logic now lives in the per-op serializers). Keep `MOVED_DOCUMENT_ACTION_ENDPOINTS` / `LEGACY_DOCUMENT_ACTION_METHODS` (still used by the view's deprecation warning).
+
+- [ ] **Step 3: Rewrite `_has_document_permissions` to consume `PermissionRequirements`**
+
+```python
+def _has_document_permissions(self, *, user, documents, op, parameters) -> bool:
+    if user.is_superuser:
+        return True
+    document_objs = Document.objects.select_related("owner").filter(pk__in=documents)
+    reqs = op.required_permissions(parameters)
+    ok = user.has_perm("documents.change_document") and all(
+        has_perms_owner_aware(user, "change_document", doc) for doc in document_objs
+    )
+    if ok and reqs.ownership:
+        ok = all((doc.owner == user or doc.owner is None) for doc in document_objs)
+    if ok and reqs.add_document:
+        ok = user.has_perm("documents.add_document")
+    if ok and reqs.delete_document:
+        ok = user.has_perm("documents.delete_document")
+    return ok
+```
+
+- [ ] **Step 4: Route BOTH call sites through the op — they obtain the op differently**
+
+There are two distinct paths, and `_execute_document_action` does **NOT** read `validated_data["method"]` (its serializers have no `method` field — it receives the operation as an argument). Handle each:
+
+- **Delete** `METHOD_NAMES_REQUIRING_USER`, `METHOD_NAMES_REQUIRING_TRIGGER_SOURCE` (note: it is an alias — `METHOD_NAMES_REQUIRING_TRIGGER_SOURCE = METHOD_NAMES_REQUIRING_USER` at `views.py:2687` — so they are one object), and `MODIFIED_FIELD_BY_METHOD`.
+
+- **`BulkEditView.post`** (`views.py:2852-2947`) — the `/bulk_edit/` path: `op = serializer.validated_data["method"]` (the registry object `validate_method` now returns). Replace `method.__name__ in METHOD_NAMES_REQUIRING_USER` → `op.needs_user`; trigger-source check → `op.needs_trigger_source`; the permission call → `_has_document_permissions(op=op, ...)`; `method(documents, **parameters)` → `op.execute(documents, **parameters)`. Audit block: `modified_field = op.audit_field` (replaces `MODIFIED_FIELD_BY_METHOD.get(method.__name__)`), reason → `f"Bulk edit: {op.name}"`. Snapshot/`log_create` otherwise unchanged.
+
+- **`_execute_document_action`** (`views.py:2764-2807`) — the moved single-action path used by six views: change its signature from `method` to `op: BulkEditOperation`. Inside, replace `method.__name__ in METHOD_NAMES_REQUIRING_USER` → `op.needs_user`; trigger check → `op.needs_trigger_source`; `_has_document_permissions(method=method, ...)` → `_has_document_permissions(op=op, ...)`; `method(documents, **parameters)` → `op.execute(documents, **parameters)`. This path has **no** audit block — leave it that way. `op.clean_parameters` is **not** called here: each moved view's own serializer (`RotateDocumentsSerializer`, `MergeDocumentsSerializer`, …) already validated its parameters; the op supplies only needs_user / needs_trigger_source / required_permissions / execute.
+
+- **The six caller views** (`RotateDocumentsView:2964`, `MergeDocumentsView:2991`, `DeleteDocumentsView:3018`, `ReprocessDocumentsView:3045`, `EditPdfDocumentsView:3072`, `RemovePasswordDocumentsView:3099`): change each `method=bulk_edit.<fn>` argument to `op=BULK_EDIT_OPERATIONS["<name>"]` (e.g. `op=BULK_EDIT_OPERATIONS["rotate"]`).
+
+- [ ] **Step 5: Run the FULL regression + matrix suites**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_api_bulk_edit.py src/documents/tests/test_bulk_operations.py -v"`
+Expected: PASS — every existing `test_api_bulk_edit.py` test (patch targets still bite via invariant #1; `__name__`-dependent asserts gone), plus Task 1's matrix unchanged. If a `documents.serialisers.bulk_edit.X` / `documents.views.bulk_edit.X` patch stops biting, invariant #1 or #2 is violated — check the import style and that `execute` does call-time lookup.
+
+- [ ] **Step 6: Run the broader API + audit suites** (signals/audit log touch this path)
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_api_documents.py src/documents/tests/test_api_bulk_download.py -k bulk or audit -v"`
+Expected: PASS.
+
+- [ ] **Step 7: Lint & commit**
+
+```bash
+ruff check src/documents/serialisers.py src/documents/views.py && ruff format src/documents/serialisers.py src/documents/views.py
+git add src/documents/serialisers.py src/documents/views.py

+
+## Task 4: Registry-driven OpenAPI examples
+
+**Files:**
+
+- Modify: `src/documents/views.py`
+- Test: `src/documents/tests/test_bulk_operations.py`
+
+- [ ] **Step 1: Write a failing test that every example validates**
+
+```python
+class TestBulkEditExamples:
+    def test_every_operation_has_a_valid_example(self) -> None:
+        from documents.views import _bulk_edit_examples
+        examples = _bulk_edit_examples()
+        assert {e.summary for e in examples} == set(ops.BULK_EDIT_OPERATIONS)
+        for ex in examples:
+            op = ops.BULK_EDIT_OPERATIONS[ex.value["method"]]
+            if op.parameter_serializer_class is not None:
+                s = op.parameter_serializer_class(data=ex.value["parameters"], context={...})
+                assert s.is_valid(), s.errors
+```
+
+- [ ] **Step 2: Implement the helper and wire `@extend_schema`**
+
+First add the import — `OpenApiExample` is **not** currently in `views.py` (extend the existing `from drf_spectacular.utils import ...` line):
+
+```python
+from drf_spectacular.utils import OpenApiExample
+```
+
+```python
+def _bulk_edit_examples() -> list[OpenApiExample]:
+    return [
+        OpenApiExample(
+            name=op.name, summary=op.name,
+            value={"documents": [1, 2], "method": op.name, "parameters": op.example_parameters},
+            request_only=True,
+        )
+        for op in BULK_EDIT_OPERATIONS.values()
+    ]
+```
+
+Add `examples=_bulk_edit_examples()` to the existing `bulk_edit` `extend_schema(...)` (`views.py:2811-2825`). Leave `operation_id`, `description`, and the `responses` inline serializer unchanged.
+
+- [ ] **Step 3: Run the example test + a schema smoke check**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_bulk_operations.py::TestBulkEditExamples -v"`
+Then regenerate the OpenAPI schema on the VM and confirm the diff is **examples-only** — the `method` enum membership/order is byte-identical and the request/response structure is unchanged:
+
+```bash
+ssh -o BatchMode=yes -p 2244 trenton@localhost 'bash -lc "cd ~/projects/paperless-ngx && uv run manage.py spectacular --file /tmp/schema.yml"'
+```
+
+Expected: schema generates without error; the `bulk_edit` `method` enum lists the 16 methods in canonical order; examples appear.
+
+- [ ] **Step 4: Lint & commit**
+
+```bash
+ruff check src/documents/views.py && ruff format src/documents/views.py
+git add src/documents/views.py src/documents/tests/test_bulk_operations.py

+- [ ] **Step 2: Type-check on the VM (pyrefly, with baseline)**
+
+```bash

+
+Grep to verify no orphaned references remain: `MODIFIED_FIELD_BY_METHOD`, `METHOD_NAMES_REQUIRING_USER`, `_validate_parameters_`, and `method.__name__` in `views.py` should all be gone; `bulk_edit.<fn>` should appear only inside `bulk_operations.py` `execute` methods.
+
+---
+
+## Notes for the implementer
+
+- **The permission matrix is the whole ballgame.** A wrong `required_permissions` cell is a privilege-escalation bug, not a cosmetic one. Task 1's parametrized characterization test (written and green _before_ the refactor) is the guardrail — never weaken a case to make the refactor pass; if it goes red, the production code is wrong.
+- **Preserve `ValidationError` message text verbatim** when porting `_validate_parameters_*` into the per-op serializers — `test_api_bulk_edit.py` asserts specific strings (e.g. the three distinct "only one document" messages, the all=true message, "out of bounds", "update_document only allowed with a single output document").
+- **Two call sites, obtained differently.** `BulkEditView.post` reads `op` from `validated_data["method"]` and owns the audit logging; `_execute_document_action` receives `op` as an argument from its **six** caller views (which change `method=bulk_edit.<fn>` → `op=BULK_EDIT_OPERATIONS["<name>"]`) and has no audit. Convert both paths and all six caller views; Task 1 must characterize both before cutover.
+- **`redo_ocr` stays unregistered** (dead/unreachable today; registering it would newly accept it on the wire).
+- **Out of scope:** a discriminated `oneOf` request schema for `parameters` — examples (Task 4) are the agreed approach; the polymorphic schema is a possible later follow-up (the discriminator `method` and payload `parameters` are sibling fields, which `PolymorphicProxySerializer` does not model cleanly).

+# Export Zip Compression Control Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add `--zip-compression {stored,deflated,bzip2,lzma,zstd}` and `--zip-compression-level N` flags to `document_exporter`, threaded into `ZipExportSink`, with import-side safety for codecs the running Python can't read.
+
+**Architecture:** A new pure-data module `documents/export/compression.py` owns the method↔constant map, per-method level bounds, the runtime availability probe, and a compress-type readability check. `ZipExportSink` gains `compression`/`compresslevel` constructor params. The command validates flags up front (fail-fast `CommandError`) and constructs the sink; the importer pre-checks entry compress types before extracting.
+
+**Tech Stack:** Python ≥3.11 (zstd only on 3.14+), `zipfile`, `compression.zstd` (PEP 784), pytest + pytest-mock + factory-boy. Backend tests run on the Linux VM (Python 3.11 — zstd positive tests are `skipif`-guarded); `ruff` runs locally.
+
+**Spec:** `docs/superpowers/specs/2026-06-16-export-zip-compression-design.md`
+
+**PREREQUISITE:** The base refactor `docs/superpowers/plans/2026-06-16-export-sink-architecture.md` MUST be merged first. This plan assumes `src/documents/export/sinks.py` exists with `ZipExportSink(target, zip_name, *, delete=False)` opening its `ZipFile` in `_open()`.
+
+---
+
+## Verified facts (CPython 3.14.3, via `uv run --python 3.14 --no-project`)
+
+- Constants: `ZIP_STORED=0`, `ZIP_DEFLATED=8`, `ZIP_BZIP2=12`, `ZIP_LZMA=14`, `ZIP_ZSTANDARD=93` (zstd added 3.14; absent on < 3.14).
+- `ZipFile(file, "w", compression=…, compresslevel=…)` applies both as the default for every `write`/`writestr` — no per-entry args needed (verified).
+- Level bounds: `deflated` 0–9, `bzip2` 1–9, `lzma`/`stored` ignore level, `zstd` -131072…22 (`compression.zstd.CompressionParameter.compression_level.bounds() == (-131072, 22)`).
+- An invalid level fails at the **first write** (`ValueError: Invalid initialization option` / `compresslevel must be between 1 and 9`), plus GC-time `AttributeError` noise on close — hence up-front validation.
+- zstd is backed by `compression.zstd`; `zipfile` raises `RuntimeError` if it's unavailable.
+
+## Conventions for every task
+
+- **Run backend tests on the VM:** `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "<targets>"` (never locally).
+- **Lint locally:** `ruff check <paths> && ruff format <paths>` (global ruff, not `uv run`).
+- **Tests are pytest-style:** classes, `@pytest.mark.django_db` on the class only where DB is needed (the `compression.py` and sink tests need no DB), factory-boy, `mocker`, `parametrize`, full type annotations.
+- The VM runs Python 3.11, so **zstd positive tests must be `@pytest.mark.skipif(...)`-guarded**; they will simply not run there. zstd _rejection_ tests (the < 3.14 path) DO run on the VM.
+
+## File structure
+
+- **Create** `src/documents/export/compression.py` — method map, CLI choices, level bounds, `compression_available()`, `level_error()`, `compress_type_readable()`, `unreadable_method_names()`. Pure, no Django.
+- **Create** `src/documents/tests/export/test_compression.py` — unit tests for the above.
+- **Modify** `src/documents/export/sinks.py` — `ZipExportSink.__init__` gains `compression`/`compresslevel`; `_open()` passes them to `ZipFile`.
+- **Modify** `src/documents/tests/export/test_sinks.py` — assert the chosen `compress_type` is applied.
+- **Modify** `src/documents/management/commands/document_exporter.py` — add the two CLI flags, up-front validation, and pass resolved values to `ZipExportSink`.
+- **Modify** `src/documents/tests/test_management_exporter.py` — flag validation + default-unchanged tests.
+- **Modify** `src/documents/management/commands/document_importer.py` — pre-extract compress-type check.
+- **Modify** `src/documents/tests/test_management_importer.py` — unsupported-codec → `CommandError`.
+- **Modify** `docs/administration.md` — document both flags + zstd portability caveat.

+                "deflated: 0-9, bzip2: 1-9, zstd: -131072..22; ignored for "
+                "stored/lzma."
+            ),
+        )
+```
+
+- [ ] **Step 2: Read + validate the flags in `handle()`**
+
+In `handle()`, after the existing `--compare-*` + `--zip` guard, add the compression flag handling. Insert before the sink construction:
+
+```python
+        zip_compression: str | None = options["zip_compression"]
+        zip_compression_level: int | None = options["zip_compression_level"]
+
+        if not self.zip_export and (
+            zip_compression is not None or zip_compression_level is not None
+        ):
+            raise CommandError(
+                "--zip-compression and --zip-compression-level require --zip",
+            )
+
+        compression_method = zip_compression or "deflated"
+        if self.zip_export:
+            if not compression_available(compression_method):
+                if compression_method == "zstd" and ZSTD is None:
+                    raise CommandError(
+                        "zstd compression requires Python 3.14 or newer",
+                    )
+                raise CommandError(
+                    f"Compression method '{compression_method}' is not "
+                    f"available on this Python runtime",
+                )
+            level_msg = level_error(compression_method, zip_compression_level)
+            if level_msg is not None:
+                raise CommandError(level_msg)
+```
+
+- [ ] **Step 3: Pass the resolved values into `ZipExportSink`**
+
+Change the `ZipExportSink(...)` construction in `handle()` to:
+
+```python
+        if self.zip_export:
+            sink = ZipExportSink(
+                self.target,
+                options["zip_name"],
+                delete=self.delete,
+                compression=COMPRESSION_METHODS[compression_method],
+                compresslevel=zip_compression_level,
+            )
+        else:
+            sink = DirectoryExportSink(
+                self.target,
+                compare_checksums=self.compare_checksums,
+                compare_json=self.compare_json,
+                delete=self.delete,
+            )
+```
+
+- [ ] **Step 4: Write the command-level tests**
+
+Add to the `TestExportImport` class in `src/documents/tests/test_management_exporter.py` (imports `call_command`, `CommandError`, `ZipFile`, `timezone` already present):
+

+
+- [ ] **Step 5: Run the tests**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_management_exporter.py -v"`
+Expected: PASS — the new tests plus all existing exporter tests stay green.
+
+- [ ] **Step 6: Lint**
+
+Run: `ruff check src/documents/management/commands/document_exporter.py src/documents/tests/test_management_exporter.py && ruff format src/documents/management/commands/document_exporter.py src/documents/tests/test_management_exporter.py`
+Expected: no errors.
+

+
+```bash

+## Task 4: Importer pre-check for unreadable codecs
+
+**Files:**
+
+- Modify: `src/documents/management/commands/document_importer.py`
+- Test: `src/documents/tests/test_management_importer.py`
+
+- [ ] **Step 1: Write the failing test**
+
+The importer test file `src/documents/tests/test_management_importer.py` is
+`TestCase`-style (`class TestCommandImport(... TestCase)`, `self.assertRaises`,
+`DirectoriesMixin` gives `self.dirs.scratch_dir`). Match that style. Add this
+method to `TestCommandImport`. It builds a valid zip and patches the readability
+probe so the check fires deterministically on any runtime:
+
+```python
+    def test_import_rejects_unreadable_compression(self) -> None:
+        """
+        GIVEN:
+            - A zip archive with an entry whose compression this Python can't read
+        WHEN:

+        THEN:
+            - A CommandError naming the issue is raised, before extraction
+        """
+        import zipfile
+        from unittest import mock
+
+        archive = Path(self.dirs.scratch_dir) / "export.zip"
+        with zipfile.ZipFile(archive, "w") as zf:
+            zf.writestr("manifest.json", "[]")
+
+        with mock.patch(
+            "documents.management.commands.document_importer.compress_type_readable",
+            return_value=False,
+        ):
+            with self.assertRaises(CommandError) as e:
+                call_command(
+                    "document_importer",
+                    str(archive),
+                    "--no-progress-bar",
+                    skip_checks=True,
+                )
+        self.assertIn("compression", str(e.exception))
+```
+
+- [ ] **Step 2: Run to verify it fails**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_management_importer.py -k unreadable_compression -v"`
+Expected: FAIL — no pre-check exists yet, so the import proceeds (or fails with a different error).
+
+- [ ] **Step 3: Implement the pre-check**
+
+In `document_importer.py`, add the import:
+
+```python
+from documents.export.compression import compress_type_readable
+from documents.export.compression import unreadable_method_names
+```
+
+Find the zip-handling block (around `document_importer.py:453`):
+
+```python
+                with ZipFile(self.source) as zf:
+                    zf.extractall(tmp_dir)
+```
+
+Replace it with a pre-check before extraction:
+
+```python
+                with ZipFile(self.source) as zf:
+                    unsupported = {
+                        info.compress_type
+                        for info in zf.infolist()
+                        if not compress_type_readable(info.compress_type)
+                    }
+                    if unsupported:
+                        names = ", ".join(sorted(unreadable_method_names(unsupported)))
+                        raise CommandError(
+                            f"This archive uses compression this Python cannot "
+                            f"read ({names}). zstd archives require Python 3.14+.",
+                        )
+                    zf.extractall(tmp_dir)
+```
+
+Confirm `CommandError` is imported in `document_importer.py` (it is used elsewhere; if not, add `from django.core.management.base import CommandError`).
+
+- [ ] **Step 4: Run to verify it passes**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_management_importer.py -v"`
+Expected: PASS — the new test plus all existing importer tests (normal deflated/stored archives still import).
+
+- [ ] **Step 5: Lint**
+
+Run: `ruff check src/documents/management/commands/document_importer.py src/documents/tests/test_management_importer.py && ruff format src/documents/management/commands/document_importer.py src/documents/tests/test_management_importer.py`
+Expected: no errors.
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/documents/management/commands/document_importer.py src/documents/tests/test_management_importer.py
+git commit -m "Feature: importer rejects archives with unreadable compression"
+```
+
+---
+
+## Task 5: Document the flags
+
+**Files:**
+
+- Modify: `docs/administration.md`
+
+- [ ] **Step 1: Add the flags to the option list**
+
+In `docs/administration.md`, update the usage block (around line 257) to include the new flags:
+
+```
+document_exporter target [-c] [-d] [-f] [-na] [-nt] [-p] [-sm] [-z]
+
+optional arguments:
+-c,  --compare-checksums
+-cj, --compare-json
+-d,  --delete
+-f,  --use-filename-format
+-na, --no-archive
+-nt, --no-thumbnail
+-p,  --use-folder-prefix
+-sm, --split-manifest
+-z,  --zip
+-zn, --zip-name
+--zip-compression
+--zip-compression-level
+--data-only
+--no-progress-bar
+--passphrase
+```
+
+- [ ] **Step 2: Add the prose**
+
+After the `-z`/`--zip` paragraph (around line 330), add:
+
+```markdown
+The compression method for the zip can be set with `--zip-compression`
+(`stored`, `deflated` (default), `bzip2`, `lzma`, or `zstd`) and tuned with
+`--zip-compression-level` (deflated: 0–9, bzip2: 1–9, zstd: -131072–22; ignored
+for `stored` and `lzma`). Both options require `--zip`.
+
+!!! warning
+
+    `zstd` compression requires Python 3.14 or newer on **both** the machine
+    creating the export and any machine importing it. An archive compressed with
+    `zstd` (or `lzma`/`bzip2` where those modules are unavailable) cannot be
+    imported on a runtime that lacks the codec; the importer will refuse it with
+    a clear error. The default `deflated` is universally readable.
+```
+
+- [ ] **Step 3: Verify the docs build is not broken (lint markdown)**
+
+Run: `ruff check docs/ 2>/dev/null; echo "docs are markdown; rely on prettier pre-commit"`
+(No code to test. The prettier pre-commit hook will reformat on commit.)
+
+- [ ] **Step 4: Commit**
+
+```bash
+git add docs/administration.md
+git commit -m "Docs: document --zip-compression and --zip-compression-level"
+```
+
+---
+
+## Task 6: Final verification
+
+**Files:** none (verification only).
+
+- [ ] **Step 1: Full backend suites on the VM**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/export/ src/documents/tests/test_management_exporter.py src/documents/tests/test_management_importer.py -v"`
+Expected: PASS, no failures.
+
+- [ ] **Step 2: Spot-check the zstd happy path on Python 3.14 (cannot run under Django on the 3.11 VM)**
+
+The zstd positive round-trip can't run in the 3.11 test env. Confirm the policy module behaves on a real 3.14 interpreter with a standalone check (no Django needed):
+
+Run:
+
+```bash
+uv run --python 3.14 --no-project python -c "import sys; sys.path.insert(0,'src'); import django; print('skip')" 2>/dev/null || \
+uv run --python 3.14 --no-project python -c "
+import zipfile, io
+from compression.zstd import CompressionParameter as CP
+print('zstd const', zipfile.ZIP_ZSTANDARD, 'bounds', CP.compression_level.bounds())
+buf = io.BytesIO()
+with zipfile.ZipFile(buf,'w',compression=zipfile.ZIP_ZSTANDARD,compresslevel=19) as zf:
+    zf.writestr('a.txt','x'*1000)
+with zipfile.ZipFile(buf) as zf:
+    assert zf.getinfo('a.txt').compress_type == zipfile.ZIP_ZSTANDARD
+    assert zf.read('a.txt') == b'x'*1000
+print('zstd round-trip OK')
+"
+```
+
+Expected: prints `zstd const 93 bounds (-131072, 22)` and `zstd round-trip OK`. This validates the constant, bounds, and that a zstd archive round-trips — the parts the 3.11 CI cannot exercise.
+
+- [ ] **Step 3: Type-check on the VM (pyrefly)**
+
+```bash
+tar czf - src pyproject.toml uv.lock .pyrefly-baseline.json | ssh -o BatchMode=yes -p 2244 trenton@localhost 'tar xzf - -C ~/projects/paperless-ngx'
+ssh -o BatchMode=yes -p 2244 trenton@localhost 'bash -lc "cd ~/projects/paperless-ngx && uv run pyrefly check"'
+```
+
+Expected: no new type errors beyond the baseline. (Note: `import compression.zstd` is guarded behind `importlib.import_module`, so it is never statically resolved on the 3.11 baseline.)
+
+- [ ] **Step 4: Final lint**
+
+Run: `ruff check src/documents/export/ src/documents/management/commands/document_exporter.py src/documents/management/commands/document_importer.py && ruff format --check src/documents/export/ src/documents/management/commands/document_exporter.py src/documents/management/commands/document_importer.py`
+Expected: clean.
+
+---
+
+## Notes for the implementer
+
+- **Default behavior is unchanged:** with no flags, the sink is constructed with `compression=ZIP_DEFLATED, compresslevel=None` — byte-method-identical to today (`shutil.make_archive` used `ZIP_DEFLATED` with no level). `test_default_zip_uses_deflate` pins this.
+- **zstd availability is gated three ways and never imported statically:** the constant via `getattr`, the codec via `importlib.import_module("compression.zstd")`, and the CLI value rejected with a friendly message on < 3.14. The choices list always contains `zstd` so argparse doesn't hide it.
+- **The importer pre-check is the safety net** for portability foot-guns — without it an unreadable entry raises a bare `NotImplementedError` mid-`extractall`. The check runs on `infolist()` (metadata only) before any extraction.
+- **Why `--zip-compression` defaults to `None`, not `"deflated"`:** so `handle()` can detect "user passed it without `--zip`" and fail fast. The effective default is resolved as `zip_compression or "deflated"`.

+# Ingestion Staging & Enqueue Unification Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Extract staging + enqueue of `consume_file` into one `documents/ingest.py`, give every staged document a single per-document `work_root` cleaned on all terminal paths (fixing the scratch leak), and collapse the three test seams to one.
+
+**Architecture:** `ingest.py` owns `SOURCE_TO_TRIGGER`, `build_consume_signature` (returns a Celery `Signature`), `enqueue_consumption` (dispatches it), and `stage_document` (a commit-on-success guard owning a per-document temp dir). `ConsumableDocument` gains `staging_dir`; `consume_file` derives a `work_root` from it and `rmtree`s it in a `finally`. Sites call the seam **module-qualified** so one patch target intercepts all.
+
+**Tech Stack:** Python ≥3.11, Django, Celery (`Signature`/`chord`), pytest + pytest-mock + factory-boy. Backend tests run on the Linux VM (Windows host); `ruff` runs locally.
+
+**Spec:** `docs/superpowers/specs/2026-06-16-ingestion-staging-unification-design.md`
+
+---
+
+## Conventions for every task
+
+- **Run backend tests on the VM:** `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "<targets>"` (never locally — the lockfile is linux/macOS only).
+- **Lint locally:** `ruff check <paths> && ruff format <paths>` (global ruff, not `uv run`).
+- **Tests are pytest-style** where new: classes, `@pytest.mark.django_db` on the class only where DB is needed, `mocker`, `parametrize`, full type annotations. Do **not** convert the existing Django-`TestCase` suites; only repoint their patch targets where a task says so.
+- **Two load-bearing constraints from the spec** (the whole "one patch point" rests on them):
+  1. Every site calls the seam **module-qualified**: `from documents import ingest` then `ingest.enqueue_consumption(...)` / `ingest.build_consume_signature(...)` — never `from documents.ingest import enqueue_consumption`.
+  2. `build_consume_signature` builds the signature with **keyword** args (`consume_file.s(input_doc=…, overrides=…)`), so `Signature.kwargs` keeps the shape mail tests assert on.
+
+## File structure
+
+- **Create** `src/documents/ingest.py` — `SOURCE_TO_TRIGGER`, `build_consume_signature`, `enqueue_consumption`, `StagedDocument`, `stage_document`.
+- **Create** `src/documents/tests/test_ingest.py` — unit tests for the module + `consume_file` cleanup.
+- **Modify** `src/documents/data_models.py` — add `ConsumableDocument.staging_dir`.
+- **Modify** `src/documents/tasks.py` — `consume_file` derives `work_root`, cleans `staging_dir`.
+- **Modify** `src/documents/management/commands/document_consumer.py` — folder site.
+- **Modify** `src/documents/views.py` — API/WebUI + version sites.
+- **Modify** `src/paperless_mail/mail.py` — attachment + `.eml` sites via `ExitStack`.
+- **Modify** `src/documents/barcodes.py` — split children via the module + per-child work_roots.
+- **Modify** `src/documents/tests/utils.py` — rewrite `ConsumeTaskMixin`.
+- **Modify** consumer/version/mail test files — repoint patch targets (per task).

+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_ingest.py::TestConsumeFileWorkRoot -v"`

+
+- [ ] **Step 3: Add the `staging_dir` field**
+
+In `src/documents/data_models.py`, add the field to `ConsumableDocument` (before the `init=False` `mime_type`):
+
+```python
+    source: DocumentSource
+    original_file: Path
+    root_document_id: int | None = None

+    mailrule_id: int | None = None
+    staging_dir: Path | None = None
+    mime_type: str = dataclasses.field(init=False, default=None)
+```
+
+`Path | None` is picklable, so the HMAC-pickle Celery serializer is unaffected.
+
+- [ ] **Step 4: Derive `work_root` and clean it in `consume_file`**
+
+In `src/documents/tasks.py`, add `import shutil` and `from contextlib import contextmanager` (if not present), then add a helper above `consume_file`:
+
+```python
+@contextmanager
+def _consume_working_dir(input_doc: ConsumableDocument):
+    """Yield the plugins' working directory.
+
+    Staged sources reuse their per-document work_root (a `work/` subfolder);
+    folder source gets a throwaway TemporaryDirectory. Removal of the staged
+    work_root itself happens in consume_file's finally, so it covers every
+    terminal path (success, stop, duplicate, exception)."""
+    if input_doc.staging_dir is not None:
+        work = Path(input_doc.staging_dir) / "work"
+        work.mkdir(parents=True, exist_ok=True)
+        yield work
+    else:
+        with TemporaryDirectory(dir=settings.SCRATCH_DIR) as tmp:
+            yield Path(tmp)
+```
+
+Then change the body of `consume_file` so the `with` uses the helper and the
+`finally` removes `staging_dir`:
+
+```python
+    token = consume_task_id.set((self.request.id or "")[:8])
+    try:
+        if overrides is None:
+            overrides = DocumentMetadataOverrides()
+
+        plugins: list[type[ConsumeTaskPlugin]] = (
+            [ConsumerPreflightPlugin, ConsumerPlugin]
+            if input_doc.root_document_id is not None
+            else [
+                ConsumerPreflightPlugin,
+                AsnCheckPlugin,
+                CollatePlugin,
+                BarcodePlugin,
+                AsnCheckPlugin,  # Re-run ASN check after barcode reading
+                WorkflowTriggerPlugin,
+                ConsumerPlugin,
+            ]
+        )
+
+        with (
+            ProgressManager(
+                overrides.filename or input_doc.original_file.name,
+                self.request.id,
+            ) as status_mgr,
+            _consume_working_dir(input_doc) as tmp_dir,
+        ):
+            msg = None
+            for plugin_class in plugins:
+                # ... unchanged plugin loop ...
+                ...
+        return msg
+    finally:

+        if input_doc.staging_dir is not None:
+            shutil.rmtree(input_doc.staging_dir, ignore_errors=True)
+```
+
+Only the `with` line and the `finally` change; the plugin loop body is untouched
+(`tmp_dir` is still a `Path`). The early `return ConsumeFileStoppedResult(...)` /
+`return ConsumeFileDuplicateResult(...)` and the re-`raise` all pass through the
+`finally`, so the staged work_root is removed on every terminal path.
+
+- [ ] **Step 5: Run the new tests + the full consume/import regression**

+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_ingest.py src/documents/tests/test_consumer.py -v"`

+## Task 4: Migrate the consume-folder site
+
+**Files:**
+
+- Modify: `src/documents/management/commands/document_consumer.py:340-353`
+- Test: `src/documents/tests/test_management_consumer.py:99-103`
+
+- [ ] **Step 1: Repoint the consumer test fixture**
+
+In `src/documents/tests/test_management_consumer.py`, change the mock fixture (lines ~99-103) to patch the seam instead of the module-local task:
+
+```python
+@pytest.fixture
+def mock_consume_file_delay(mocker: MockerFixture) -> MagicMock:
+    """Mock the enqueue seam used by the consumer."""
+    return mocker.patch(
+        "documents.management.commands.document_consumer.ingest.enqueue_consumption",
+    )
+```
+
+Then, wherever tests assert on the queued call, they now read positional args.
+Update the two assertion shapes used in this file:
+
+- `mock_consume_file_delay.apply_async.assert_called_once()` → `mock_consume_file_delay.assert_called_once()`
+- `call_args.kwargs["kwargs"]["input_doc"]` → `call_args.args[0]`; `["overrides"]` → `call_args.args[1]`
+
+- [ ] **Step 2: Run to verify the consumer tests now fail**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_management_consumer.py -v"`
+Expected: FAIL — the folder site still calls `consume_file.apply_async`, not the seam, so the mock is never called.
+
+- [ ] **Step 3: Migrate the folder enqueue site**
+
+In `src/documents/management/commands/document_consumer.py`, add `from documents import ingest` at the top, and replace the enqueue block (lines ~340-353):
+
+```python
+    # Queue for consumption
+    try:
+        logger.info(f"Adding {filepath} to the task queue")
+        ingest.enqueue_consumption(
+            ConsumableDocument(
+                source=DocumentSource.ConsumeFolder,
+                original_file=filepath,
+            ),
+            DocumentMetadataOverrides(tag_ids=tag_ids),
+        )
+    except Exception:
+        logger.exception(f"Error while queuing document {filepath}")
+```
+
+Folder source builds a `ConsumableDocument` with `staging_dir=None` (the default)
+because the file already lives in `CONSUMPTION_DIR`; it does not use
+`stage_document`. The `trigger_source` header now comes from `SOURCE_TO_TRIGGER`
+inside `build_consume_signature`, so the explicit `headers=` is gone. Remove the
+now-unused `consume_file` import from this module if present.
+

+        )
+        self.consume_file_mock = self.consume_file_patcher.start()
+        super().setUp()
+
+    def tearDown(self) -> None:
+        super().tearDown()
+        self.consume_file_patcher.stop()
+
+    def assert_queue_consumption_task_call_args(
+        self,
+    ) -> tuple[ConsumableDocument, DocumentMetadataOverrides]:
+        self.consume_file_mock.assert_called_once()
+        args = self.consume_file_mock.call_args.args
+        return (args[0], args[1])
+
+    def get_all_consume_task_call_args(
+        self,
+    ) -> Iterator[tuple[ConsumableDocument, DocumentMetadataOverrides]]:
+        self.consume_file_mock.assert_called()
+        for call in self.consume_file_mock.call_args_list:
+            yield (call.args[0], call.args[1])
+```
+
+This patches `documents.ingest.enqueue_consumption`, which intercepts every site
+that calls it module-qualified (folder already does; API/version after Step 3).
+Mail does not use `enqueue_consumption`, so this mock does not affect mail tests.
+
+- [ ] **Step 2: Run to verify API tests now fail**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_api_documents.py -k upload -v"`
+Expected: FAIL — `PostDocumentView` still calls `consume_file.apply_async`, so the seam mock is never called (`assert_called_once` fails). Confirms the mixin is wired but the site isn't migrated yet.
+
+- [ ] **Step 3: Migrate `PostDocumentView.post`**
+
+In `src/documents/views.py`, ensure `from documents import ingest` is imported,
+then replace the staging + dispatch (lines ~3149-3192) with a `stage_document`
+block:
+
+```python
+        from_webui = serializer.validated_data.get("from_webui")
+        source = DocumentSource.WebUI if from_webui else DocumentSource.ApiUpload
+
+        t = int(mktime(datetime.now().timetuple()))
+
+        with ingest.stage_document(source, name=doc_name) as staged:
+            staged.write(doc_data)
+            os.utime(staged.path, times=(t, t))
+            input_doc = staged.build()
+
+            custom_fields = None
+            if isinstance(cf, dict) and cf:
+                custom_fields = cf
+            elif isinstance(cf, list) and cf:
+                custom_fields = dict.fromkeys(cf, None)
+
+            input_doc_overrides = DocumentMetadataOverrides(
+                filename=doc_name,
+                title=title,
+                correspondent_id=correspondent_id,
+                document_type_id=document_type_id,
+                storage_path_id=storage_path_id,
+                tag_ids=tag_ids,
+                created=created,
+                asn=archive_serial_number,
+                owner_id=request.user.id,
+                custom_fields=custom_fields,
+            )
+
+            async_task = ingest.enqueue_consumption(input_doc, input_doc_overrides)
+            staged.release()
+
+        return Response(async_task.id)
+```
+
+The old `SCRATCH_DIR.mkdir` + `mkdtemp` + `write_bytes` + the explicit
+`headers=` block are all replaced by `stage_document` + `enqueue_consumption`.
+
+- [ ] **Step 4: Migrate `update_version`**
+
+In `src/documents/views.py` `update_version` (lines ~1917-1976), replace its
+`mkdtemp`/`write`/`consume_file.apply_async` with the same pattern, preserving its
+specific fields (`root_document_id`, `version_label`, `actor_id`):
+
+```python
+        with ingest.stage_document(DocumentSource.WebUI, name=doc_name) as staged:
+            staged.write(doc_data)
+            input_doc = staged.build(root_document_id=root_doc.pk)
+            overrides = DocumentMetadataOverrides(
+                version_label=version_label,
+                actor_id=request.user.id,
+            )
+            async_task = ingest.enqueue_consumption(input_doc, overrides)
+            staged.release()
+```
+
+(Match the exact existing variable names for `doc_name`/`doc_data`/`version_label`
+at that site; the shape above is the transformation.)
+
+- [ ] **Step 5: Repoint the version test patch target**
+
+In `src/documents/tests/test_api_document_versions.py`, change the patch from
+`documents.views.consume_file` to `documents.ingest.enqueue_consumption`, and the
+assertion from `consume_mock.apply_async.call_args.kwargs["kwargs"]["input_doc"]`
+to `consume_mock.call_args.args[0]` (and `args[1]` for overrides).
+
+- [ ] **Step 6: Run the API + version suites**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_api_documents.py src/documents/tests/test_api_document_versions.py src/documents/tests/test_api_post_document_nfc.py -v"`
+Expected: PASS. `test_api_post_document_nfc.py` patches `documents.tasks.consume_file.apply_async` directly — repoint that fixture to `documents.ingest.enqueue_consumption` and read `call_args.args[0]` if it fails.
+
+- [ ] **Step 7: Lint & commit**
+
+```bash
+ruff check src/documents/views.py src/documents/tests/utils.py && ruff format src/documents/views.py src/documents/tests/utils.py
+git add src/documents/views.py src/documents/tests/utils.py src/documents/tests/test_api_document_versions.py src/documents/tests/test_api_post_document_nfc.py
+git commit -m "Refactor: route API/WebUI/version ingest through the staging seam"
+```

+
+## Task 6: Migrate mail (attachment + `.eml`) with `ExitStack`
+
+**Files:**
+
+- Modify: `src/paperless_mail/mail.py` (`_handle_message` ~716-760, `_process_attachments` ~861-908, `_process_eml` ~952-1006)
+- Test: `src/paperless_mail/tests/test_mail.py`, `test_mail_nfc.py` (verify, likely no change)
+
+- [ ] **Step 1: Wrap the message's staging in an `ExitStack`**
+
+`build_consume_signature` already uses keyword args, so the mail tests that patch
+`paperless_mail.mail.queue_consumption_tasks` and assert on
+`consume_task.kwargs["input_doc"]` keep working. Add `import contextlib` and
+`from documents import ingest` to `mail.py`. Restructure `_handle_message` so all
+of a message's staged docs share one `ExitStack`, released only after
+`queue_consumption_tasks` dispatches:
+
+```python
+    def _handle_message(self, message, rule) -> int:
+        processed = 0
+        with contextlib.ExitStack() as staging_stack:
+            consume_tasks: list[Signature] = []
+            staged_docs: list[ingest.StagedDocument] = []
+
+            if rule.consumption_scope in (...EML scopes...):
+                self._process_eml(message, rule, staging_stack, consume_tasks, staged_docs)
+            if rule.consumption_scope in (...attachment scopes...):
+                processed += self._process_attachments(
+                    message, rule, staging_stack, consume_tasks, staged_docs,
+                )
+
+            if consume_tasks:
+                queue_consumption_tasks(
+                    consume_tasks=consume_tasks, rule=rule, message=message,
+                )
+                for staged in staged_docs:
+                    staged.release()
+        return processed
+```
+
+(Match the file's actual scope-branching; the load-bearing parts are: one
+`ExitStack` for the whole message, `release()` only after `queue_consumption_tasks`
+returns, so a chord-dispatch failure unwinds the stack and rmtrees every staged
+work_root for the message.)
+
+- [ ] **Step 2: Stage each attachment via the stack**
+
+Replace the attachment staging (`mail.py:861-908`) inside `_process_attachments`:
+
+```python
+                staged = staging_stack.enter_context(
+                    ingest.stage_document(DocumentSource.MailFetch, name=att.filename or ""),
+                )
+                staged.write(att.payload)
+                input_doc = staged.build(mailrule_id=rule.pk)
+                staged_docs.append(staged)
+
+                attachment_name = input_doc.original_file.name
+                doc_overrides = DocumentMetadataOverrides(
+                    title=title,
+                    filename=attachment_name,
+                    correspondent_id=correspondent.id if correspondent else None,
+                    document_type_id=doc_type.id if doc_type else None,
+                    tag_ids=tag_ids,
+                    owner_id=(
+                        rule.owner.id
+                        if (rule.assign_owner_from_rule and rule.owner)
+                        else None
+                    ),
+                )
+                consume_tasks.append(
+                    ingest.build_consume_signature(input_doc, doc_overrides),
+                )
+```
+
+The old `SCRATCH_DIR.mkdir` + `mkdtemp` + `write_bytes` + `consume_file.s(...).set(...)`
+are gone; `stage_document` handles the temp dir and `build_consume_signature` the
+header. Do the analogous replacement in `_process_eml` (`mail.py:952-1006`),
+staging the `.eml` bytes and building the signature the same way.
+
+- [ ] **Step 3: Run the mail suites**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_mail/tests/test_mail.py src/paperless_mail/tests/test_mail_nfc.py src/paperless_mail/tests/test_preprocessor.py -v"`
+Expected: PASS. The assertions on `consume_task.kwargs["input_doc"]`/`["overrides"]`
+hold because `build_consume_signature` uses keyword args. If any fail on
+`input_doc.original_file` existence, ensure `staged.write(...)` precedes
+`staged.build(...)`.
+
+- [ ] **Step 4: Lint & commit**
+
+```bash
+ruff check src/paperless_mail/mail.py && ruff format src/paperless_mail/mail.py

+
+## Task 7: Migrate barcode split children (per-child work_roots)
+
+**Files:**
+
+- Modify: `src/documents/barcodes.py:183-230`
+- Test: `src/documents/tests/test_barcodes.py`
+
+- [ ] **Step 1: Replace the shared dir + `_SOURCE_TO_TRIGGER` with per-child staging**
+
+In `src/documents/barcodes.py`, add `from documents import ingest`, delete the
+local `_SOURCE_TO_TRIGGER` dict (lines ~198-207) and the shared `mkdtemp`
+(lines ~188-194), and stage each child separately:
+
+```python
+            # Create the split document tasks — each child gets its OWN work_root,
+            # so its consume_file task can clean it independently.
+            for new_document in self.separate_pages(separator_pages):
+                with ingest.stage_document(
+                    self.input_doc.source,
+                    name=new_document.name,
+                ) as staged:
+                    staged.write_from(new_document)
+                    input_doc = staged.build(
+                        mailrule_id=self.input_doc.mailrule_id,
+                        original_path=self.input_doc.original_file,
+                    )
+                    task = ingest.enqueue_consumption(input_doc, self.metadata)
+                    staged.release()
+                logger.info(f"Created new task {task.id} for {new_document.name}")
+```
+
+This removes the sixth hand-rolled site and the duplicated trigger map; each child
+is independently cleaned by its own `consume_file` `finally`. The parent's own
+temp tree is unaffected (children are copied out via `write_from`).
+
+- [ ] **Step 2: Run the barcode suite**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_barcodes.py -v"`
+Expected: PASS. If a test patched `documents.tasks.consume_file.apply_async` to
+inspect child dispatch, repoint it to `documents.ingest.enqueue_consumption` and
+read `call_args.args[0]`.
+
+- [ ] **Step 3: Lint & commit**
+
+```bash
+ruff check src/documents/barcodes.py && ruff format src/documents/barcodes.py
+git add src/documents/barcodes.py src/documents/tests/test_barcodes.py
+git commit -m "Refactor: barcode split children use per-child staging + ingest seam"
+```
+

+
+## Task 8: Fold `ConsumerPlugin`'s redundant working dir into the handed-in `tmp_dir`
+
+This is the consolidation noted in the spec; do it last so the regression net is
+already stable. **Keep `ConsumerPlugin`'s success-path unlink of `original_file`** —
+folder source needs it (its loose file in `CONSUMPTION_DIR` is removed on success).
+
+**Files:**
+
+- Modify: `src/documents/consumer.py:417-422`
+- Test: `src/documents/tests/test_consumer.py`
+
+- [ ] **Step 1: Use the handed-in working dir instead of a second `TemporaryDirectory`**
+
+`ConsumerPlugin` already receives the task's working dir as `self.base_tmp_dir`
+(the `tmp_dir` arg from `tasks.py:227-233`). Replace its own
+`tempfile.TemporaryDirectory(...)` (`consumer.py:417`) with a subfolder of that
+handed-in dir:
+
+```python
+        # For the actual work, copy the file into the task-provided working dir
+        tmpdir = self.base_tmp_dir / "consumer"
+        tmpdir.mkdir(parents=True, exist_ok=True)
+        self.working_copy = tmpdir / Path(self.filename)
+        copy_file_with_basic_stats(self.input_doc.original_file, self.working_copy)
+        self.unmodified_original = None
+        # ... rest of the method body unchanged, de-indented out of the old `with` ...
+```
+
+Confirm the qpdf `--replace-input` recovery (`unmodified_original`,
+`consumer.py:452+`) still resolves paths under `tmpdir`. Removing the `with` means
+the working copy is now cleaned by the task's `work_root`/`TemporaryDirectory`
+teardown instead of the plugin's own context — which is the intended consolidation.
+
+- [ ] **Step 2: Run the consumer + full ingest regression**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_consumer.py src/documents/tests/test_ingest.py -v"`
+Expected: PASS.
+
+- [ ] **Step 3: Lint & commit**
+
+```bash
+ruff check src/documents/consumer.py && ruff format src/documents/consumer.py
+git add src/documents/consumer.py
+git commit -m "Refactor: ConsumerPlugin reuses the task working dir"
+```
+
+---
+
+## Task 9: Full verification
+
+- [ ] **Step 1: Run every affected suite together**
+
+Run: `bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/documents/tests/test_ingest.py src/documents/tests/test_consumer.py src/documents/tests/test_api_documents.py src/documents/tests/test_api_document_versions.py src/documents/tests/test_management_consumer.py src/documents/tests/test_barcodes.py src/documents/tests/test_double_sided.py src/documents/tests/test_workflows.py src/paperless_mail/tests/ -v"`
+Expected: PASS, no failures.
+
+- [ ] **Step 2: Type-check on the VM (pyrefly)**
+
+```bash
+tar czf - src pyproject.toml uv.lock .pyrefly-baseline.json | ssh -o BatchMode=yes -p 2244 trenton@localhost 'tar xzf - -C ~/projects/paperless-ngx'
+ssh -o BatchMode=yes -p 2244 trenton@localhost 'bash -lc "cd ~/projects/paperless-ngx && uv run pyrefly check"'
+```
+
+Expected: no new errors beyond the baseline.
+
+- [ ] **Step 3: Final lint**
+
+Run: `ruff check src/documents/ src/paperless_mail/mail.py && ruff format --check src/documents/ingest.py src/documents/tasks.py src/documents/views.py src/paperless_mail/mail.py src/documents/barcodes.py src/documents/consumer.py`
+Expected: clean.
+
+- [ ] **Step 4: Confirm the leak is closed (manual reasoning check)**
+
+Verify by inspection that every staged source now sets `staging_dir` and that
+`consume_file`'s `finally` removes it: API (Task 5), version (Task 5), mail (Task 6),
+barcode children (Task 7). Folder source sets `staging_dir=None` and is unchanged.
+
+---
+
+## Notes for the implementer
+
+- **The "one patch point" is real only with both constraints** (Conventions): module-qualified calls + keyword-arg signatures. If you import `enqueue_consumption` as a bare name into a site, `documents.ingest.enqueue_consumption` patches will silently miss it and tests will fail confusingly.
+- **`bulk_edit.py` is intentionally NOT in this plan** (8 dispatch sites, ~35 tests) — it's the phase-2 follow-up. Its `consume_file.apply_async`/`.s` calls keep working unchanged; do not touch them here.
+- **Double-sided** is out of the work_root model: its first-half preservation is a `shutil.move` to `SCRATCH_DIR` (`double_sided.py:~134`) performed before the `StopConsumeTaskError`, so the parent `rmtree` in Task 3 is safe. `test_double_sided.py` must stay green (Task 9).
+- **`staging_dir is None` must remain a strict no-op** in `consume_file` — the many real-task integration tests (`test_workflows.py`, `test_barcodes.py`, `test_double_sided.py`) build `ConsumableDocument`s by hand without it.
+- **Enabled future work (not here):** the single `finally` in `consume_file` is the one hook for a future "quarantine failed files to a review folder" feature — relocate `staging_dir` instead of `rmtree` on a genuine exception.

+# Pluggable Document Storage Design
+
+**Date:** 2026-04-23
+**Status:** Approved
+
+## Overview
+
+Replace the hardcoded local filesystem storage in paperless-ngx with a pluggable `DocumentStorage` Protocol. Ship two built-in backends — `LocalFilesystemBackend` (default, zero config change) and `S3CompatibleBackend` (supports AWS S3 and any S3-compatible endpoint). Third parties can implement the Protocol to provide their own backends.
+
+## Scope
+
+- **In scope:** original documents, PDF/A archives
+- **Out of scope:** thumbnails (stay on local filesystem, regenerable), consumption directory (stays local)
+- **Frontend impact:** none — S3 is invisible; Django proxies all file access
+
+## Protocol
+
+Defined in `src/paperless/storage.py`:
+
+```python
+class DocumentStorage(Protocol):
+    def __enter__(self) -> Self: ...
+    def __exit__(self, exc_type, exc_val, exc_tb) -> None: ...
+    def open(self, name: str) -> IO[bytes]: ...
+    def save(self, name: str, content: IO[bytes]) -> str: ...  # returns actual name used
+    def delete(self, name: str) -> None: ...
+    def exists(self, name: str) -> bool: ...
+    def move(self, old_name: str, new_name: str) -> None: ...
+    def list_files(self, prefix: str = "") -> Iterable[str]: ...
+    def size(self, name: str) -> int: ...
+```
+
+`name` is always the relative key as stored in the DB (e.g. `2024/my-invoice.pdf`). All operations including `open()` must be called within a `with storage:` block — the context manager handles connection lifecycle and backend-specific cleanup.
+
+## Storage Instances
+
+Two module-level singletons in `src/paperless/storage.py`, each an instance of the configured backend class:
+
+```python
+original_storage: DocumentStorage = _build("originals")
+archive_storage: DocumentStorage  = _build("archive")
+```
+
+`_build(prefix)` reads `PAPERLESS_DOCUMENT_STORAGE_BACKEND` and `PAPERLESS_DOCUMENT_STORAGE_OPTIONS` from settings, instantiates the backend class with the configured options plus the paperless-controlled prefix. The prefix distinguishes originals from archives within the same bucket or directory root — it is not stored in the DB key.
+
+## Configuration
+
+Two new settings, using the existing key-value dict mechanism:
+
+| Setting                              | Default                                    | Description                                                  |
+| ------------------------------------ | ------------------------------------------ | ------------------------------------------------------------ |
+| `PAPERLESS_DOCUMENT_STORAGE_BACKEND` | `paperless.storage.LocalFilesystemBackend` | Dotted Python path to any class satisfying `DocumentStorage` |
+| `PAPERLESS_DOCUMENT_STORAGE_OPTIONS` | `{}`                                       | Dict of kwargs passed to the backend constructor             |
+
+**Example — S3-compatible:**
+
+```
+PAPERLESS_DOCUMENT_STORAGE_BACKEND=paperless.storage.S3CompatibleBackend
+PAPERLESS_DOCUMENT_STORAGE_OPTIONS={"bucket_name": "my-docs", "endpoint_url": "https://s3.wasabi.com", "region_name": "us-east-1", "access_key": "...", "secret_key": "..."}
+```
+
+Existing users set nothing — `LocalFilesystemBackend` with no options is the default.
+
+## Built-in Backends
+
+### `LocalFilesystemBackend`
+
+- `__enter__`: initialises tracking of directories affected during the context
+- `__exit__`: calls `delete_empty_directories()` for all tracked dirs; no-op on exception
+- `open/save/delete/exists/move`: direct `Path` + `shutil` operations rooted at `settings.ORIGINALS_DIR` / `settings.ARCHIVE_DIR` (via the prefix passed by `_build`)
+- `move()`: `shutil.move()` — atomic on same filesystem
+- `list_files()`: `Path.rglob("*")`
+
+### `S3CompatibleBackend`
+
+- Wraps `django-storages` S3 backend (`storages.backends.s3boto3.S3Boto3Storage`) for `open`, `save`, `delete`, `exists`
+- `__enter__`: initialises boto3 client/session
+- `__exit__`: no cleanup required (no empty directory concept on S3)
+- `move()`: boto3 `copy_object` (server-side, no data transfer) + `delete_object`
+- `open()`: returns streaming S3 response body; caller's `with` block closes the HTTP connection
+- `list_files()`: S3 `list_objects_v2` with prefix
+- Works with any S3-compatible endpoint via `endpoint_url` option
+
+## Data Migration
+
+One Django migration strips the stored prefix from existing rows:
+
+- `document.filename`: `documents/originals/2024/invoice.pdf` → `2024/invoice.pdf`
+- `document.archive_filename`: `documents/archive/2024/invoice.pdf` → `2024/invoice.pdf`
+
+The prefix is now owned by the storage instance, not the DB key.
+
+## `migrate_storage` Management Command
+
+```
+manage.py migrate_storage [--dry-run] [--no-delete]
+    [--source-backend=<dotted.path>] [--source-options=<json>]
+```
+
+Transfers all document files from one storage backend to another. The user updates `PAPERLESS_DOCUMENT_STORAGE_BACKEND` in their config first, then runs this command to move existing files.
+
+The destination is always the currently configured backend (from settings). The source is specified via `--source-backend` / `--source-options`, defaulting to `LocalFilesystemBackend` with no options if omitted (covering the most common migration path: local → S3).
+
+**Flow:**
+
+1. Instantiate source backend (from CLI args or default) and destination backend (from current settings)
+2. Iterate `Document.objects.only("filename", "archive_filename")`
+3. For each file (original + archive):
+   - Skip with warning if missing from source
+   - Skip silently if already present on destination (idempotent — safe to re-run)
+   - Copy: `destination.save(name, source.open(name))`
+   - Unless `--no-delete`: `source.delete(name)`
+4. Report counts: moved / skipped / failed
+5. `--dry-run`: prints actions without touching files
+
+Individual failures are logged and counted but do not abort the run. Bidirectional: local → S3, S3 → local, S3 → S3.

+
+## Locking & Concurrency
+
+The codebase serialises all document file write/move operations with `FileLock(settings.MEDIA_LOCK)`, where `MEDIA_LOCK = MEDIA_ROOT / "media.lock"`. This is used in `consumer.py`, `signals/handlers.py`, `tasks.py`, `mail.py`, `document_importer.py`, and `document_exporter.py`.
+
+**The lock file stays on the local filesystem regardless of backend.** `MEDIA_LOCK` lives under `MEDIA_ROOT`, which is the local path even when documents are stored on S3. This means:
+
+- **Single-host deployments** (the common case — Docker Compose, single server): the `FileLock` continues to work correctly. All Celery workers and the Django process share the same lock file. No change required.
+- **Multi-host deployments**: the `FileLock` is already broken for these today — each host has its own lock file. This is a pre-existing limitation and is out of scope for this feature.
+
+**Callsite structure** — the storage context manager nests inside the existing lock, preserving current behaviour:
+
+```python
+with FileLock(settings.MEDIA_LOCK):
+    with original_storage as storage:
+        storage.move(old_name, new_name)
+```
+
+**`generate_unique_filename` race:** this function checks `storage.exists()` then saves, which is not atomic on S3. The `FileLock` already serialises this on a single host. For multi-host this is a pre-existing gap — not introduced by this feature.
+
+**Future path for multi-host:** replace `FileLock` with a database-level advisory lock or Redis lock. Out of scope here.
+
+## Key Invariants
+
+- The context manager is required for all storage operations, including reads
+- `name` is always the relative key — never an absolute path or URL
+- The backend prefix (`originals` / `archive`) is paperless-controlled and never stored in the DB
+- `LocalFilesystemBackend` is the default — existing deployments require no config change
+- The migrate command is idempotent and can be re-run after partial failure

+# Scheduled Backup Design
+
+**Date**: 2026-05-15
+**Status**: Approved
+
+## Overview
+
+Add a scheduled backup system to paperless-ngx that exports documents as zip files on a user-configurable schedule, retaining the last N backups. The schedule timing is configured via an env var (consistent with all other scheduled tasks), while the backup-specific configuration (output directory, keep count) lives in a new database model editable through the API and UI.
+
+## Goals
+
+- Automated periodic exports without manual intervention
+- Zip-based output for simple, unambiguous rotation
+- Opt-in: no backup runs unless explicitly configured
+- Strongly typed export contract usable by both the CLI and the scheduled task
+- UI-editable backup config, no additional env vars beyond the cron schedule
+
+## Non-Goals
+
+- Encrypted backups (future enhancement)
+- Age-based or size-based rotation (count-only for now)
+- Remote/cloud backup destinations
+- Import automation
+
+---
+
+## Section 1: Data Model and API
+
+### `BackupConfiguration` model
+
+New singleton model in `src/paperless/models.py`, following the same `AbstractSingletonModel` pattern as `ApplicationConfiguration`.
+
+```python
+class BackupConfiguration(AbstractSingletonModel):
+    output_dir = models.CharField(
+        verbose_name=_("Backup output directory"),
+        max_length=1024,
+        blank=True,
+        default="",
+    )
+    keep_count = models.PositiveIntegerField(
+        verbose_name=_("Number of backups to keep"),
+        default=5,
+        help_text=_("Set to 0 to keep all backups."),
+    )
+
+    class Meta:
+        verbose_name = _("Backup configuration")
+```
+
+- `output_dir` blank/empty means backup is disabled (the task treats it as a no-op).
+- `output_dir` must be an absolute path. The serializer validates this via a custom validator; `run_export` also calls `.resolve()` on the path unconditionally.
+- `keep_count = 0` means keep all backups; no rotation is performed.
+
+### Migration
+
+The migration is created in `src/paperless/migrations/` (not `src/documents/migrations/`), since `BackupConfiguration` lives in the `paperless` app.
+
+### API
+
+- **Serializer**: `BackupConfigurationSerializer` in `src/paperless/serialisers.py`
+- **ViewSet**: `BackupConfigurationViewSet` in `src/paperless/views.py` — singleton GET/PATCH, same pattern as `ApplicationConfiguration`
+- **Route**: `/api/backup_config/` registered in `src/paperless/urls.py`
+
+---
+
+## Section 2: Export Module
+
+New module `src/documents/export.py` contains the export contract and core logic, extracted from `document_exporter`'s `handle()` method.
+
+### `ExportOptions` dataclass
+
+```python
+@dataclass
+class ExportOptions:
+    target: Path
+    compare_checksums: bool = False
+    compare_json: bool = False
+    delete: bool = False
+    use_filename_format: bool = False
+    no_archive: bool = False
+    no_thumbnail: bool = False
+    use_folder_prefix: bool = False
+    split_manifest: bool = False
+    zip_export: bool = False
+    zip_name: str | None = None   # None -> default date-based name
+    data_only: bool = False
+    passphrase: str | None = None
+    batch_size: int = 500
+```
+
+`zip_name = None` means the caller wants the default date-based name. `run_export` resolves `None` internally to `f"export-{timezone.localdate().isoformat()}"` before use — callers never need to supply a default. The scheduled task always passes an explicit timestamped name.
+
+### `run_export(options: ExportOptions) -> None`
+
+The body of the current `Command.handle()` in `document_exporter` moves here, reading from `ExportOptions` instead of parsed CLI options. No behaviour changes.
+
+### Refactored `document_exporter` management command
+
+Becomes a thin CLI adapter:
+
+1. Parse arguments (unchanged)
+2. Construct `ExportOptions` from parsed args
+3. Call `run_export(options)`
+
+---
+
+## Section 3: Scheduled Task and Rotation
+
+### `scheduled_backup` task in `src/documents/tasks.py`
+
+```
+1. Load BackupConfiguration (singleton)
+2. If output_dir is blank, log a debug message and return (no-op, no PaperlessTask created)
+3. Create a PaperlessTask record (TriggerSource.SCHEDULED) to track this run
+4. Build zip_name as local-time timestamp: "export-YYYY-MM-DD-HHMMSS"
+   using Django's timezone.localtime()
+5. Construct ExportOptions(
+       target=Path(config.output_dir),
+       zip_export=True,
+       zip_name=zip_name,
+   )
+6. Call run_export(options)
+7. If keep_count > 0:
+       zips = sorted(Path(config.output_dir).glob("export-*.zip"), key=lambda p: p.stat().st_mtime)
+       for old_zip in zips[:-keep_count]:
+           old_zip.unlink()
+8. Mark PaperlessTask as complete (handled by signal handlers)
+```
+
+Key design notes:
+
+- Rotation uses `export-*.zip` glob, not `*.zip`, to avoid matching zip files in the directory that paperless did not create.
+- Rotation occurs only after a successful export, so a failed run does not consume a rotation slot.
+- The timestamp format `YYYY-MM-DD-HHMMSS` in local time ensures multiple runs per day produce distinct filenames without collision.
+
+### PaperlessTask integration
+
+`PaperlessTask` lifecycle is managed entirely by the Celery signal handlers in `src/documents/signals/handlers.py`, not manually inside the task body.
+
+**Changes to `TRACKED_TASKS` and `PaperlessTask.TaskType`:**
+
+- Add `PaperlessTask.TaskType.BACKUP` to the `TaskType` enum in `src/documents/models.py`
+- Add `"documents.tasks.scheduled_backup": PaperlessTask.TaskType.BACKUP` to `TRACKED_TASKS`
+
+**Conditional tracking — the no-op case:**
+
+When `BackupConfiguration.output_dir` is blank the task returns immediately, so no record should appear in the Tasks panel. This requires explicit handling in all five signal handlers. Relying on incidental safety (filters that match 0 rows, `DoesNotExist` guards) is fragile and unclear to future maintainers.
+
+The approach for each handler when the task type is `BACKUP`:
+
+| Handler                       | Current behaviour when no record exists                                | Required change                                                                                   |
+| ----------------------------- | ---------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------- |
+| `before_task_publish_handler` | Creates the record                                                     | Check `BackupConfiguration.get_solo().output_dir`; skip `PaperlessTask.objects.create()` if blank |
+| `task_prerun_handler`         | `.filter().update()` — silent no-op                                    | Add explicit early return if `BACKUP` task type and no record exists for `task_id`                |
+| `task_postrun_handler`        | `DoesNotExist: return` — incidentally safe                             | Add explicit early return if `BACKUP` task type and no record exists for `task_id`                |
+| `task_failure_handler`        | `.filter().first()` returns `None`, update skipped — incidentally safe | Add explicit early return if `BACKUP` task type and no record exists for `task_id`                |
+| `task_revoked_handler`        | `.filter().update()` — silent no-op                                    | Add explicit early return if `BACKUP` task type and no record exists for `task_id`                |
+
+Extract a helper `_backup_task_is_tracked(task_id: str) -> bool` that returns `PaperlessTask.objects.filter(task_id=task_id).exists()`. The four downstream handlers call this after the `TRACKED_TASKS` check and return early if it returns `False` for a `BACKUP` task. This makes the intent explicit: "this task was intentionally not tracked for this invocation."
+
+---
+
+## Section 4: Beat Schedule
+
+Add to the task list in `parse_beat_schedule()` in `src/paperless/settings/custom.py`:
+
+```python
+{
+    "name": "Scheduled document backup",
+    "env_key": "PAPERLESS_EXPORT_TASK_CRON",
+    "env_default": "disable",
+    "task": "documents.tasks.scheduled_backup",
+    "options": {
+        "expires": 1.0 * 60.0 * 60.0,  # 1 hour
+    },
+},
+```
+
+- Default is `"disable"` — the task is not added to the beat schedule unless the env var is explicitly set.
+- Setting `PAPERLESS_EXPORT_TASK_CRON=disable` (or simply not setting it) produces no scheduled task and no noise.
+- Typical user value: `"0 2 * * *"` (daily at 02:00 local server time).
+- `expires` is set to 1 hour: if a scheduled backup has not started within 1 hour of its trigger time (e.g., the Celery worker was down), it is discarded rather than running late. Unlike other tasks whose expiry is tied to a known default interval, this task has a user-defined schedule. 1 hour is a conservative value that prevents stale backup tasks from piling up without being so short that it causes problems on a normally-running worker.
+
+---
+
+## Section 5: Frontend
+
+Location to be decided by co-maintainer (dedicated "Backup" page vs. section within Application Settings). The API contract is independent of this decision.
+
+The UI requires two fields:
+
+- **Output directory** — text input for `output_dir` (absolute path on the server)
+- **Keep count** — number input for `keep_count`, with a note that 0 means keep all
+
+The component performs a GET to `/api/backup_config/` on load and a PATCH on save, identical to how the Application Settings component works.
+
+---

+
+- **`src/paperless/tests/test_backup_config.py`** — model, serializer, API (GET/PATCH)

+- **`src/documents/tests/test_tasks_backup.py`** — `scheduled_backup` task: no-op when `output_dir` blank, export called with correct options, rotation deletes correct files, rotation skipped when `keep_count=0`
+- **`src/documents/tests/test_task_signals.py`** — signal handler behaviour for `BACKUP` task type: no record created when `output_dir` blank, all downstream handlers skip cleanly when no record exists, normal lifecycle when `output_dir` is set
+- Frontend unit tests for the settings component

+# Workflow Runner Refactor — Design
+
+**Date:** 2026-05-19
+**Branch base:** `dev`
+**Status:** Approved design, pending implementation plan
+
+## Problem
+
+Workflow execution and the Django signal layer have repeatedly produced fragile,
+hard-to-fix bugs (see the revert/refix history around password removal: #12803,
+#12814, #12716, and the filename race #12386). Three structural causes:
+
+1. **`run_workflows` is dual-mode.** A single function handles both consumption
+   (mutating a `DocumentMetadataOverrides`) and post-save (mutating a real
+   `Document`), branching on a `use_overrides` flag. The branching is
+   concentrated in two places — the action dispatch inside `run_workflows`
+   (`handlers.py:931-1001`) and `build_workflow_action_context`
+   (`actions.py:33-83`), each with two full code paths. The `apply_*` helpers in
+   `workflows/mutations.py` are _already_ split by target type
+   (`apply_assignment_to_document` vs `apply_assignment_to_overrides`, etc.); the
+   refactor unifies their callers, not the helpers themselves.
+
+2. **File location is an implicit, timing-dependent side channel.** The
+   `DOCUMENT_ADDED` workflow fires from `run_workflows_added`, which runs while
+   the consumer is still inside its transaction — _before_ the consumed file is
+   copied to `document.source_path` (`document_consumption_finished` is sent at
+   `consumer.py:658`; the file copy happens after, at `consumer.py:670+`). The
+   staged path is therefore threaded through as `original_file` /
+   `caller_supplied_original_file` parameters. Actions that read the file
+   (password removal, email attachments) depend on this plumbing being correct.
+
+3. **The workflow run races the filename rename.** `update_filename_and_move_files`
+   is a raw `post_save` receiver on `Document`. When a workflow persists its
+   changes via `document.save(update_fields=[...])`, that save fires `post_save`
+   and runs the rename _while the workflow is still executing_. Under concurrent
+   Celery/UI updates the interleaved `refresh_from_db()` calls corrupt state. The
+   comment at `handlers.py:980-984` — deliberately excluding `filename` /
+   `archive_filename` from the workflow save — is a load-bearing workaround for
+   exactly this.
+
+Note: `run_workflows_added` / `run_workflows_updated` are connected to the
+_custom_ signals `document_consumption_finished` / `document_updated`, fired
+explicitly by paperless code in a handful of known sites — not to raw Django
+`post_save`. Only `update_filename_and_move_files` is a raw `post_save` receiver.
+This refactor does not change where workflows are triggered from.
+
+## Scope
+
+In scope:
+
+- Refactor `run_workflows` and its action helpers around an execution-context
+  abstraction.
+- Delete the `original_file` side-channel plumbing.
+- Make the workflow-execution → persist → rename sequence explicit and
+  deterministic.
+
+Out of scope:
+
+- Changing where/when workflows are triggered (custom signal call sites unchanged).
+- Reworking the matching logic (`matching.document_matches_workflow`).
+- Any change to workflow models, serializers, or the REST API.
+
+## Design
+
+### 1. `WorkflowRunContext` protocol
+
+New module `documents/workflows/context.py` defining a `typing.Protocol`:
+
+```
+WorkflowRunContext (Protocol)
+  source_file: Path                       # where the file actually is, now
+  build_placeholder_context() -> dict
+  apply_assignment(action) -> None
+  apply_removal(action) -> None
+  persist() -> None                        # commit accumulated mutations
+  record_run(workflow, trigger_type) -> None
+```
+
+Two concrete implementations (which need not import the Protocol — structural
+typing):
+
+- **`ConsumptionContext`** — wraps `ConsumableDocument` + `DocumentMetadataOverrides`.
+  `source_file` returns the staged file path. Mutations land on the overrides.
+  `persist()` is a no-op (the overrides object is returned to the caller).
+- **`PersistedContext`** — wraps a real `Document`. Mutations land on the
+  in-memory `Document`. `persist()` performs a single save.
+
+**Context selection** — `run_workflows` picks the context from the call shape:
+
+- CONSUMPTION trigger (`ConsumableDocument` + non-`None` `overrides`) →
+  `ConsumptionContext`.
+- DOCUMENT_ADDED / DOCUMENT_UPDATED / SCHEDULED (a real `Document`,
+  `overrides=None`) → `PersistedContext`.
+
+**`source_file` for `PersistedContext`.** It cannot unconditionally return
+`document.source_path`: for the `DOCUMENT_ADDED` trigger the file has not yet
+been moved there. The staged path is therefore passed into the `PersistedContext`
+_at construction time_ by `run_workflows_added` (which still receives it from the
+`document_consumption_finished` signal). `source_file` returns that staged path
+when supplied, otherwise `document.source_path`. This relocates the staged-path
+information from a chain of function parameters into a single piece of
+construction state — the `original_file` / `caller_supplied_original_file`
+_parameter plumbing_ through `run_workflows` and the action helpers is what gets
+deleted, not the staged path itself.
+
+`WorkflowRunContext` is a plain `Protocol`, not `@runtime_checkable` — the runner
+constructs the context itself, so no `isinstance` check is needed. Genuinely
+shared logic goes into module-level helper functions, not a base class.
+
+### 2. `run_workflows` becomes branch-free
+
+`run_workflows` keeps its current public signature so all call sites are
+unchanged. Its body:
+
+1. Construct the appropriate context once, from the argument types.
+2. Run a single flat match-and-dispatch loop over matching workflows/actions,
+   delegating every action to context methods.
+
+No `use_overrides` flag anywhere. The branching currently scattered across
+`run_workflows`, `build_workflow_action_context`, and the `apply_*` helpers
+collapses into the two context classes.
+
+### 3. File staging via `source_file`
+
+`source_file` is a property of the context, fixed at construction. The
+`original_file` and `caller_supplied_original_file` parameters threaded through
+`run_workflows` and the `execute_*` helpers are deleted; each context resolves
+the path itself (see "Context selection" above).
+
+**Deferred password removal.** `execute_password_removal_action`, when given a
+`ConsumableDocument`, currently installs a one-shot handler on
+`document_consumption_finished` that picks up `original_file` from `kwargs`
+later (`actions.py:295-308`). This deferred hook lives outside the context
+abstraction. The refactor must explicitly decide its fate: either keep it as-is
+(the context still constructs correctly around it) or fold the deferral into
+`ConsumptionContext`. This is called out as an open implementation decision, not
+silently absorbed.
+
+### 4. Explicit workflow → persist → rename sequencing
+
+What must be deferred is the **file rename**, not the DB save. `run_workflows`
+keeps its per-workflow `document.refresh_from_db()` at the top of each iteration
+— that is deliberate concurrency protection against `bulk_update_documents`
+running simultaneously. Deferring all saves to a single final `persist()` would
+let one workflow's refresh wipe a prior workflow's in-memory changes. So:
+
+1. `run_workflows` refreshes and applies actions per workflow, and
+   `PersistedContext.persist()` saves after each matching workflow, as today.
+2. The save deliberately **continues to exclude** `filename` /
+   `archive_filename` from `update_fields`. This is not duct tape: it guards a
+   _cross-process_ hazard — another Celery task may have moved the file and
+   written `filename` to the DB, and a stale in-memory `filename` in our save
+   would revert it. The `ContextVar` guard (below) only addresses _intra-process_
+   ordering, so this exclusion stays.
+3. The rename is suppressed for the whole run and invoked **exactly once,
+   afterward**, against final committed state.
+
+The actual race being fixed: `apply_assignment_to_document` assigns tags via
+`document.add_nested_tags(...)`, which fires `m2m_changed` on
+`Document.tags.through` _before_ the workflow's `document.save()`. The
+`m2m_changed` receiver `update_filename_and_move_files` then calls
+`refresh_from_db()`, wiping the workflow's in-memory correspondent/type, and
+moves the file to a path computed from stale metadata. The guard prevents this.
+
+To stop the rename from firing mid-workflow, a **`ContextVar` guard** is
+introduced (e.g. `documents/workflows/context.py` module-level
+`_workflow_in_progress: ContextVar[bool]`). `update_filename_and_move_files`
+checks the guard and early-returns when set. `run_workflows` wraps its **entire**
+persisted-path execution — not just the `persist()` call — in a context manager
+that sets the guard via `set()`/`reset(token)`. Token-based reset is
+reentrancy-safe for nested saves or nested workflow runs.
+
+The guard must span the whole execution, not just `persist()`, because
+`update_filename_and_move_files` is _also_ registered to `m2m_changed` on
+`Document.tags.through` and to `post_save` on `CustomFieldInstance`
+(`handlers.py:431-432`). A workflow action that assigns tags or custom fields
+would otherwise trigger a rename mid-workflow through those signals.
+
+After execution completes, `run_workflows` calls `persist()` once and then
+explicitly invokes the move logic once. The `ContextVar` is set/reset in the
+same thread that runs these receivers synchronously, so they always observe the
+value. (Celery `prefork` workers run each task in its own process; greenlet
+pools are also `contextvars`-aware — non-issues, noted for completeness.)
+
+The move body of `update_filename_and_move_files` is extracted into a plain
+callable that the runner invokes directly. The function is already invoked
+directly (as a plain call, bypassing the decorator) for version documents at
+`handlers.py:664-667`, so this extraction has precedent. The thin `post_save`
+receiver remains as a guard-checking wrapper.
+
+The two `post_save` receivers on `Document` are `update_filename_and_move_files`
+(`handlers.py:433`) and `update_llm_suggestions_cache` (`handlers.py:740`). The
+`ContextVar` guard suppresses **only** the former — `update_llm_suggestions_cache`
+keeps running normally, as do `document_consumption_finished` receivers such as
+`add_or_update_document_in_llm_index` (which is _not_ a `post_save` receiver).
+This is why the guard is preferred over persisting with `.update()`, which would
+silently suppress _all_ `post_save` receivers including
+`update_llm_suggestions_cache`.
+
+`WorkflowRun.objects.create(...)` is created per matching workflow as today
+(`handlers.py:998-1002`); it is a separate model and is not deferred.
+
+The comment at `handlers.py:980-984` is updated to describe the new flow
+(per-workflow save under the guard; single explicit rename afterward) but the
+`filename` / `archive_filename` exclusion it documents is kept — see point 2
+above.
+
+## Testing
+
+- **Runner loop** — exercised against a fake context implementing the
+  `WorkflowRunContext` surface that records `apply_assignment` / `apply_removal`
+  / `persist` calls. No DB document, no staged files, no signals.
+- **Concrete contexts** — `ConsumptionContext` and `PersistedContext` each get
+  focused tests: given an action, assert the mutation lands on the overrides vs.
+  the document, and that `source_file` resolves to the staged vs. final path.
+- **ContextVar guard** — assert `update_filename_and_move_files` early-returns
+  while the guard is set, and that the rename runs exactly once after
+  `persist()`.
+- **Regression: the racy case** — a workflow that reassigns metadata while the
+  document is subject to a filename template; assert final DB filename and file
+  location are consistent (the #12386 scenario).
+- **Regression safety net** — the existing `test_workflows.py` suite (~100
+  tests; ~19 `document_consumption_finished.send` sites plus many direct
+  `run_workflows(...)` calls for the `DOCUMENT_UPDATED` path) must stay green
+  **unchanged**. A test that needs editing signals a behavior change to flag
+  explicitly, not a silent refactor outcome.
+
+Per project conventions: tests grouped under classes, fixtures and test
+signatures fully type-annotated.
+
+## Implementation sequence
+
+Each step is independently reviewable and keeps the test suite green:
+
+1. Introduce the `Protocol` + the two contexts; `run_workflows` delegates to
+   them. Pure refactor, no behavior change.
+2. Move the staged path into `PersistedContext` construction (passed by
+   `run_workflows_added`); delete the `original_file` /
+   `caller_supplied_original_file` parameter plumbing through `run_workflows`
+   and the `execute_*` helpers.
+3. Extract the move body from `update_filename_and_move_files` into a callable;
+   add the `ContextVar` guard; `run_workflows` invokes the move once after the
+   run completes. The `filename` / `archive_filename` exclusion in the
+   per-workflow save is kept; only the comment at `handlers.py:980-984` is
+   updated to describe the new flow.
+
+## Pain points addressed
+
+- **Dual-mode** → eliminated by the `Protocol` + two contexts; no `use_overrides`.
+- **File staging** → `source_file` is a context property; side-channel args deleted.
+- **Rename race** → per-workflow save under a `ContextVar` guard that suppresses
+  the mid-workflow rename; a single explicit rename runs once at the end against
+  final state.

+# Interactive Shell Container Environment
+
+**Date:** 2026-05-26
+**Branch:** fix-tanvity-index-lock (to be implemented on a new branch)
+**Status:** Approved
+
+## Problem
+
+When paperless-ngx users open an interactive shell in the running container via `docker exec -it <container> bash`, they do not see environment variables resolved from `*_FILE` secret injection.
+
+The `init-env-file` s6 init script reads `PAPERLESS_*_FILE` variables (e.g. `PAPERLESS_SECRET_KEY_FILE=/run/secrets/key`), reads the referenced file, and writes the resolved value (e.g. `PAPERLESS_SECRET_KEY=abc123`) to `/run/s6/container_environment/`. All s6-managed services and management command wrappers use the `#!/command/with-contenv` shebang, which reads that directory and injects all vars into the process environment before execution.
+
+`docker exec bash` bypasses s6 entirely. It is a non-login interactive shell launched directly by the Docker daemon, which provides only the original Docker-configured environment (the `*_FILE` paths, not the resolved values). Any manual command a user runs — such as `document_exporter` or `manage.py` calls — will be missing the resolved secrets unless they happen to also be set as plain Docker env vars.
+
+## Approach
+
+Source `/run/s6/container_environment/` in every interactive bash shell opened in the container, mirroring what `with-contenv` does for s6 services.
+
+Two hooks are needed because Debian uses different rc files for different shell types:
+
+- **Non-login interactive** (`docker exec bash`): sources `/etc/bash.bashrc`
+- **Login interactive** (`docker exec bash --login`): sources `/etc/profile`, which auto-sources all `/etc/profile.d/*.sh`
+
+## Changes
+
+### 1. `docker/rootfs/etc/profile.d/contenv.sh` (new file)
+
+A POSIX-compatible shell script that exports all files in `/run/s6/container_environment/` as environment variables. Placed here so login shells pick it up automatically.
+
+```sh
+#!/bin/sh
+# Source s6 container environment for interactive shells.
+# Ensures variables resolved from *_FILE secret injection are visible
+# when using 'docker exec bash'. Does not affect s6 services (those
+# use with-contenv directly). Has no effect in non-container contexts
+# because the directory will not exist.
+# Note: sh/dash shells opened via 'docker exec sh' are not covered;
+# only bash-based sessions benefit from this file.
+_pngx_contenv="/run/s6/container_environment"
+if [ -d "${_pngx_contenv}" ]; then
+    for _pngx_f in "${_pngx_contenv}"/*; do
+        [ -f "${_pngx_f}" ] || continue
+        _pngx_name=$(basename "${_pngx_f}")
+        _pngx_val=$(cat "${_pngx_f}")
+        export "${_pngx_name}=${_pngx_val}"
+    done
+fi
+unset _pngx_contenv _pngx_f _pngx_name _pngx_val
+```
+
+### 2. Dockerfile `main-app` stage (one line added)
+
+Appends a source line to `/etc/bash.bashrc` so non-login interactive shells also pick up contenv. Added after the runtime package installation block, before the Python dependency installation.
+
+```dockerfile
+RUN echo '. /etc/profile.d/contenv.sh' >> /etc/bash.bashrc
+```
+
+`/etc/bash.bashrc` is provided by the Debian base image and installed during the apt step, so it exists by the time this `RUN` executes.
+
+## Coverage
+
+| How user gets a shell                    | Gets contenv?         | Mechanism                                |
+| ---------------------------------------- | --------------------- | ---------------------------------------- |
+| `docker exec -it container bash`         | Yes                   | `/etc/bash.bashrc` sources `contenv.sh`  |
+| `docker exec -it container bash --login` | Yes                   | `/etc/profile.d/contenv.sh` auto-sourced |
+| `docker exec -it container sh`           | No (known limitation) | `sh` sources neither file                |
+| Management command wrappers              | Already worked        | `with-contenv` shebang                   |
+| s6 services                              | Already worked        | `with-contenv` shebang                   |
+
+## Edge Cases
+
+**Shell opened before `init-env-file` completes:** The directory exists but may not yet contain all resolved vars. The script exports what is present; missing vars are simply absent. No error is produced.
+
+**Variable value contains special characters:** `$(cat file)` strips only trailing newlines (which `init-env-file` already warns about). Other special characters are preserved correctly by the `export "NAME=VALUE"` form.
+
+**Directory does not exist (non-container use):** The `[ -d ]` guard makes the script a no-op. Safe to include in any Debian-based image.
+
+## Testing
+
+No automated test is added. This is container-bootstrap shell plumbing with no Python code path. Manual verification: run the container with a `*_FILE` secret, `docker exec bash`, and confirm the resolved variable is present in the environment.

+# Friendlier advanced-search error shapes
+
+**Status:** design / ready for implementation plan.
+**Follow-up to:** the `InvalidDateQuery` work on branch `fix/search-query-translation`
+(PR #13010), itself specced in
+`docs/superpowers/done/specs/2026-06-14-search-query-translation-design.md`.
+**Builds on:** the `SearchQueryError(ValueError)` base in
+`documents/search/_translate.py` and the single `except SearchQueryError` handler
+in `UnifiedSearchViewSet.list` (`documents/views.py:2477`), which re-raises as DRF
+`ValidationError({"query": [msg]})`. Any new subclass surfaces through that one
+handler automatically, so this work is purely additive.
+
+## Problem
+
+Every advanced-search failure other than the now-handled invalid date lands in
+the view's generic `except Exception` and returns
+`HttpResponseBadRequest("Error listing search results, check logs for more
+detail.")` (`views.py:2479-2482`). `index.parse_query(...)` runs _outside_ the
+`translate_query` try/except in `parse_user_query` (`_query.py:220-235`), so
+anything Tantivy rejects bypasses `SearchQueryError` entirely and gets the
+unhelpful generic 400. Some Tantivy errors also leak Rust internals (e.g.
+`ParseIntError { kind: InvalidDigit }`) if surfaced verbatim.
+
+## Ground truth: what Tantivy raises (empirically re-verified 2026-06-15)
+
+Probed against a real index built from `documents.search._schema.build_schema` +
+`_tokenizer.register_tokenizers`, running each query through `translate_query`
+then `index.parse_query(..., DEFAULT_SEARCH_FIELDS, field_boosts=_FIELD_BOOSTS)`.
+`index.parse_query` raises `ValueError` with three distinguishable message
+families:
+
+| Family           | Example inputs                                                                                             | Tantivy message                                                    |
+| ---------------- | ---------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------ |
+| Unknown field    | `foobar:hello`, `owner:5`, `has_tags:true`, `is_shared:true`                                               | `Field does not exist: 'foobar'`                                   |
+| Syntax error     | `(invoice OR bill`, `created:[2020 TO 2021`, `invoice AND`, `OR invoice`, `title:"abc`, `:value`, `AND OR` | `Syntax Error: <echoes the whole query, no location>`              |
+| Wrong value type | `asn:notanumber`, `page_count:[foo TO bar]`                                                                | `Expected a valid integer: 'ParseIntError { kind: InvalidDigit }'` |
+
+**Parses OK (NOT errors):** `page_count:>5`, `asn:<10`, `page_count:>=5` (these
+produce _correct_ Tantivy `RangeQuery` objects — see the `>`/`<` decision below),
+`page_count:5` (TermQuery), `title:[a TO b]` (Str range on a text field),
+`title:~~~` (EmptyQuery), `` (empty query).
+
+## The `>`/`<`/`>=`/`<=` decision (investigated)
+
+The stub flagged these as "parses OK but possibly silently wrong vs Whoosh." That
+is **incorrect** — verified empirically:
+
+- `page_count:>5` -> `RangeQuery { lower_bound: Excluded(5), upper_bound: Unbounded }`
+- `page_count:>=5` -> `RangeQuery { lower_bound: Included(5), ... }`
+- `asn:<10` -> `RangeQuery { lower_bound: Unbounded, upper_bound: Excluded(10) }`
+
+Tantivy's query parser supports comparison operators natively and produces
+correct range queries. They were _never_ supported in paperless-Whoosh (no
+`GtLtPlugin`; confirmed in the base design §3 and against the old schema on
+`main`), so there is no prior behavior to "match" and nothing is silently wrong.
+
+**Decision: leave them as-is.** They work correctly and are effectively a free
+capability gain over Whoosh. Do not reject them. The numeric value validator
+(below) must explicitly _allow_ a leading `>`, `<`, `>=`, or `<=` so it does not
+wrongly reject working comparison queries. Document them as supported.
+
+Note the asymmetry (verified): the _comparison_ forms work, but _open
+bracket-ranges_ on numeric fields do NOT. `asn:[1 TO]` and `asn:[TO 10]`
+translate verbatim and Tantivy raises `Syntax Error` on them — only open _date_
+ranges are rewritten to bounded sentinels (`OPEN_LO`/`OPEN_HI`) by
+`translate_range`. So `asn:>1` works but `asn:[1 TO]` is malformed; readers must
+not assume bracket-ranges behave like the comparison operators.
+
+## Clarification: the old "Whoosh-only" fields were backend internals
+
+The stub proposed targeted "this field isn't available in full-text search; use
+the filter sidebar" messages for `owner`, `has_tags`, `is_shared`, etc. Checking
+the old Whoosh code still present on `main` (`src/documents/index.py`,
+`make_schema`) shows these were **backend filter / permission fields, not
+user-facing search syntax**:
+
+- `has_correspondent`, `has_tag`, `has_type`, `has_path`, `has_owner`,
+  `has_custom_fields`, `is_shared`, `custom_field_count`, and `owner` (username
+  text) were populated at index time so the permission and list-filter machinery
+  could query them. `get_permissions_criterias()` builds
+  `query.Term("has_owner", ...)`, `query.Term("owner_id", ...)`,
+  `query.Term("viewer_id", ...)` programmatically.
+- The user-facing full-text parser (`DelayedFullTextQuery`) advertised only
+  `["content", "title", "correspondent", "tag", "type", "notes",
+"custom_fields"]`. (Whoosh's generic `FieldsPlugin` would technically parse a
+  typed `has_tag:true`, but that was never a designed or documented feature.)
+
+**Consequence:** no curated per-field messages. These names are simply _unknown
+fields_ and flow through `UnknownFieldError` + did-you-mean like any typo. Note
+that `owner_id` and `viewer_id` legitimately remain queryable (present in
+`KNOWN_FIELDS` and the new schema, still used for permission filtering), so they
+are correctly _not_ unknown; `owner`, the `has_*` booleans, `is_shared`, and
+`custom_field_count` are correctly absent and read as plain unknown fields.
+
+## Proposed error shapes (all `SearchQueryError` subclasses)
+
+All three live next to `InvalidDateQuery` in `_translate.py` and inherit the
+"message is safe to surface" contract.
+
+### 1. `UnknownFieldError`
+
+`Unknown search field 'corespondent'.` plus a `Did you mean 'correspondent'?`
+suggestion via `difflib.get_close_matches(field, suggestion_pool, n=1)`. The
+suggestion pool is the user-facing field set derived from `KNOWN_FIELDS` (see
+single-source-of-truth below). Typos get a suggestion; names with no close match
+(e.g. `has_tags`) get the bare unknown-field message.
+
+### 2. `InvalidFieldValueError`
+
+Sibling of `InvalidDateQuery`. For numeric fields: `Field 'asn' expects a number,
+got 'notanumber'.` Carries `field` + `value` attributes like `InvalidDateQuery`.
+Removes the `ParseIntError { ... }` Rust leak.
+
+### 3. `MalformedQueryError`
+
+Structural syntax errors. A cheap balance-check pass gives specific hints for the
+common cases (unbalanced `"`, `[`, `(`, dangling/leading `AND`/`OR`) before
+falling back to a clean generic "check for unbalanced quotes, brackets, or
+parentheses." Tantivy's message has no location and echoes the whole query, so it
+is **never** surfaced verbatim.
+
+Caveat: an open numeric bracket-range (`asn:[1 TO]`) reaches this path as a
+`Syntax Error` even though its brackets are _balanced_. The balance-check must not
+confidently assert "unbalanced brackets" for it — when brackets/quotes/parens are
+balanced, fall back to the generic hint rather than a wrong-but-specific one.
+
+## Detection strategy: hybrid, split by what each layer can see
+
+The scanner and the parse-wrapper see different things; assigning each error
+shape to the layer that can detect it cleanly avoids false positives.
+
+### Proactive numeric validation in the scanner (`_translate.py`)
+
+`scan()` already tokenizes recognized `field:value` and `field:[range]` clauses
+into `FieldValue` / `FieldRange` for fields in `KNOWN_FIELDS`. Add a
+`NUMERIC_FIELDS` set (`asn`, `page_count`, `num_notes`, and the `*_id` fields)
+and validate those tokens' values during translation, raising
+`InvalidFieldValueError` before the string ever reaches `index.parse_query`.
+
+Validation rules:
+
+- Strip a single leading comparison operator (`>=`, `<=`, `>`, `<`) before the
+  integer check, so comparison queries pass.
+- For ranges, validate each present bound (`lo`, `hi`) as an integer. An empty
+  bound passes the _integer_ check (an empty string is not a bad integer), but be
+  aware that an open numeric bracket-range (`asn:[1 TO]`) is still rejected
+  downstream by Tantivy as a `Syntax Error` (see the `>`/`<` note above) — i.e.
+  the validator does not make it succeed, it falls through to the malformed path.
+  Do not emit a "bad number" message for an empty bound; let the structural error
+  surface as `MalformedQueryError`.
+- For multi-value numeric fields after comma expansion (`tag_id`, `viewer_id`),
+  validate each expanded value (`tag_id:1,foo` -> `InvalidFieldValueError`).
+
+This path owns `InvalidFieldValueError` exclusively: messages are rich,
+context-aware, and independent of Tantivy's English strings.
+
+### Why unknown-field detection is NOT proactive
+
+`_match_field_token` returns `None` for any field not in `KNOWN_FIELDS`
+(`_translate.py:193`) — an unknown `foobar:hello` is intentionally left as a
+`Passthrough` (the existing `http:`-misfire guard). Detecting unknown fields in
+the scanner would require a separate `\w+:` pass that re-introduces exactly the
+false positives that guard exists to prevent:
+
+- URLs: `http://example.com/a` (`http:`)
+- Dotted JSON subfields, which are valid: `notes.user:alice`,
+  `custom_fields.invoice_no:123` (the `\w+:` regex would see `user:` / `invoice_no:`)
+- Time-like literals: `12:30` (note: a bare `12:30` is already a parse failure
+  today — Tantivy raises `Field does not exist: '12'` — so under this design it
+  reshapes into `UnknownFieldError("12")` with no close match, i.e. the bare
+  unknown-field message. It is _not_ a clean passthrough; the point here is only
+  that a proactive `\w+:` pass would mis-flag it even more aggressively.)
+
+So unknown fields are detected in the backstop instead, where Tantivy has already
+confirmed the token is a real field reference.
+
+### Catch-and-sanitize backstop around `index.parse_query` (`_query.py`)
+
+Wrap the `index.parse_query` call(s) in `parse_user_query`. Map residual Tantivy
+`ValueError` messages by prefix:
+
+- `Field does not exist: 'X'` -> extract `X`, build `UnknownFieldError(X)` with
+  did-you-mean.
+- `Syntax Error: ...` -> `MalformedQueryError` (run the balance-check for a
+  specific hint; never echo the Tantivy text).
+- `Expected a valid integer: ...` -> `InvalidFieldValueError`. This backstop is
+  effectively _unreachable today_: every query that produces this Tantivy error
+  goes through a recognized numeric field token (`asn`, `page_count`, `num_notes`,
+  `*_id`) that `scan()` already models, so the proactive pass catches it first
+  (verified — no query reaches this branch without the proactive pass firing).
+  Its real value is forward-safety: if a future numeric field is added to the
+  schema but not to `NUMERIC_FIELDS`, this branch guarantees the raw
+  `ParseIntError { ... }` Rust struct never leaks. Keep it; the generic "expects a
+  number" message stands in when `field`/`value` cannot be recovered from the
+  Tantivy text.
+- Anything unrecognized -> re-raise, preserving today's generic-500/400 path
+  rather than inventing a misleading message.
+
+Both the fuzzy and exact `parse_query` calls go through the same wrapper.
+
+### Single source of truth for fields
+
+`KNOWN_FIELDS` (`_translate.py:63`) is the canonical set of field names a user may
+validly scope on; it already includes the v2 aliases (`type`, `path`, `type_id`,
+`path_id`) that `translate_query` rewrites to real schema names. Use it (with
+aliases optionally excluded from the _suggestion_ pool to avoid suggesting a
+deprecated alias) for both validation and did-you-mean.
+
+Add a drift-guard test asserting `KNOWN_FIELDS` minus the alias set is a subset of
+the schema field names produced by `build_schema()`, so the two definitions cannot
+silently diverge as the schema evolves. The backend-only Whoosh names (`owner`,
+`has_*`, `is_shared`, `custom_field_count`) are correctly excluded from both.
+
+## Testing
+
+New dedicated test file (per project convention), e.g.
+`src/documents/tests/test_search_error_shapes.py`:
+
+- One case per error family asserting the `SearchQueryError` subclass and a
+  user-safe message (no paths, no Rust structs, no verbatim Tantivy echo).
+- `UnknownFieldError`: typo yields a did-you-mean suggestion; a no-close-match
+  name (e.g. `has_tags`) yields the bare message.
+- `InvalidFieldValueError`: `asn:notanumber`, `page_count:[foo TO bar]`, and a
+  bad multi-value `tag_id:1,foo`.
+- **`>`/`<` working case**: `page_count:>5` / `asn:<10` / `page_count:>=5` parse
+  successfully and are NOT raised as errors (guards the numeric validator's
+  operator allowance).
+- **Open numeric range**: `asn:[1 TO]` / `asn:[TO 10]` surface as
+  `MalformedQueryError` (Tantivy `Syntax Error`, brackets balanced) and the hint
+  is the generic one, NOT a false "unbalanced brackets" claim.
+- **Dotted JSON non-regression**: `notes.user:alice`,
+  `custom_fields.name:invoice` are not flagged as unknown fields.
+- **URL behavior**: a query containing `http://...` is unchanged from today's
+  behavior — Tantivy treats `http` as a field, so it still 400s; under this design
+  the message becomes the clearer `UnknownFieldError('http')` (no close match) and
+  the proactive numeric pass does not touch it. This is a clarity gain, not a
+  regression (it already 400'd generically). Out of scope to make URL substrings
+  searchable.
+- **Message-prefix pin**: a test that asserts the exact Tantivy prefixes
+  (`Field does not exist:`, `Syntax Error:`, `Expected a valid integer:`) the
+  backstop depends on, so a `tantivy-py` upgrade that changes them fails loudly
+  instead of silently regressing to the generic 400.
+- **Drift guard**: `KNOWN_FIELDS` (minus aliases) ⊆ `build_schema()` field names.
+- View-level: each subclass surfaces as HTTP 400 with `{"query": [msg]}` through
+  the existing handler.
+
+## Risks / notes
+
+- The backstop depends on Tantivy's error _message-string prefixes_, which are
+  brittle across `tantivy-py` upgrades. The pin test above is the mitigation.
+- Keep all messages safe to surface: they may echo user input but must never
+  include internal paths, stack details, or Rust error structs.
+- The balance-check for `MalformedQueryError` is a heuristic for _hints_ only; its
+  failure mode is the clean generic message, never a wrong-but-confident one.
+
+## Out of scope
+
+- Frontend rendering of the structured `{"query": [...]}` 400 (the inline search
+  error UI). Only relevant if the messages should render differently from the
+  current generic banner; the current banner already displays the message.
+- Adding or changing `>`/`<` semantics. They work; this spec only ensures the
+  numeric validator does not break them.

+# Whoosh→Tantivy Advanced-Query Translation — Design
+
+**Date:** 2026-06-15
+**Branch base:** `dev` (Phase 1 implemented on `fix/search-query-translation`)
+**Status:** Phase 1 implemented; Phase 2 pending an upstream `tantivy-py` release (see below)
+
+## Problem
+
+The Tantivy search migration changed the advanced-query (`?query=`) syntax contract.
+A class of queries that worked under the old Whoosh backend now return an opaque
+**HTTP 400**, because the old query string is handed to `tantivy.Index.parse_query`
+which rejects forms Whoosh accepted. There is no fallback: a parse error propagates
+through `documents/search/_backend.py` and is caught by the generic handler in
+`documents/views.py` → `HttpResponseBadRequest`, with the real error only in logs.
+
+Affected query forms (all verified against real Whoosh and real Tantivy):
+
+- Bare dates on a date field: `created:2020`, `created:202003`.
+- Bracketed absolute/partial/ISO ranges: `created:[20200101 TO 20201231]`,
+  `created:[2020-01-01 TO 2020-12-31]`, `created:[202001 TO 202006]`.
+- Open-ended ranges: `created:[2020 to]`, `created:[to 2020]`.
+- Relative ranges: `added:[-1 week to now]`, `added:[now-7d TO now]`.
+- Comma-joined clauses and value lists: `created:[r],added:[r]`, `tag:foo,bar`,
+  the malformed `title:x,created:[…]`.
+- Renamed fields: `type:`/`path:` (Whoosh names) vs `document_type:`/`storage_path:`
+  (Tantivy names).
+- Invalid dates (`created:202023`) — Whoosh matched nothing (NullQuery); Tantivy 400s.
+
+The original compatibility layer was a stack of order-dependent regex substitutions,
+which had no structural awareness (could not tell a comma inside `[...]` from a clause
+separator) and required a new regex per form. This design replaces it.
+
+## Approach
+
+A structural, context-aware translation pass that intercepts only the forms Tantivy
+parses differently (dates, commas, renamed fields) and passes everything else
+(booleans, grouping, phrases, wildcards) straight through to Tantivy's own parser.
+
+Pipeline (`documents/search/_translate.py`):
+
+```
+parse_user_query(raw, tz)
+  → translate_query(raw, tz)                    # wrapped in a safety net: on any
+      → scan(raw)            depth-aware tokenizer (quotes / [] depth)
+      → resolve_commas       value-list (tag/tag_id/viewer_id) vs clause separator
+      → _render              date tokens → translate_scalar / translate_range,
+                             field aliasing, comma → AND
+      → operator normalization (spaced/trailing -/+ cleanup)
+  → index.parse_query(translated, …)            # exception → fall back to raw query
+```
+
+Date math lives in `documents/search/_dates.py` (no Django deps). The two date-field
+semantics are preserved: `created` is date-only (UTC-midnight boundaries);
+`added`/`modified` are datetimes (local-tz-midnight → UTC).
+
+### Verified compatibility contract (from running both engines)
+
+- Comma between clauses = AND, both sides preserved; comma within a `KEYWORD(commas=True)`
+  field value = value list. Multi-value fields are exactly `{tag, tag_id, viewer_id}`.
+- Invalid/unparsable dates → a no-match clause (never a 400), matching Whoosh's NullQuery.
+- Field renames to alias: `type`→`document_type`, `type_id`→`document_type_id`,
+  `path`→`storage_path`, `path_id`→`storage_path_id`. Both old and new names work.
+- Partial-date ranges floor the low bound and ceil the high bound; reversed ranges swap.
+
+## Phase 1 (implemented)
+
+Branch `fix/search-query-translation`. The full pipeline above, output as a Tantivy
+query **string**, with these workarounds for things the string parser cannot express
+on date fields:
+
+- **Open-ended ranges** use far-past / far-future string sentinels
+  (`0001-01-01T00:00:00Z` / `9999-12-31T23:59:59Z`).
+- **No-match** (unparsable date) uses a degenerate equal-bound date range.
+
+Status: complete; the full `-m search` suite passes (date forms, comma clauses, field
+aliasing, relative ranges, operator normalization, and the existing search tests now
+validating the new pipeline). The old `_rewrite_*` regex helpers were left in place as
+delegation shims during the transition.
+
+Landed in 15 commits on `fix/search-query-translation` (`f1b92a493`..`816a078a4`):
+`_dates.py` extraction → partial-date helpers → scanner → comma resolution →
+scalar/range translation → field aliasing → relative ranges + operator normalization →
+`parse_user_query` wiring + delegation + tests. Key symbols in `_translate.py`:
+`scan`, `resolve_commas`, `translate_scalar`, `translate_range`, `translate_query`;
+constants `MULTI_VALUE_FIELDS`, `DATE_FIELDS`, `KNOWN_FIELDS`, `FIELD_ALIASES`,
+`NO_MATCH`, `OPEN_LO`, `OPEN_HI`.
+
+## Phase 2 (pending — the thing being tracked)
+
+Replace the Phase-1 string workarounds with real `tantivy.Query` objects for date
+clauses, which removes the sentinel/degenerate-range hacks entirely:
+
+1. **Open bounds** via `Query.range_query(field, FieldType.Date, lower_bound=…,
+upper_bound=None)` (and vice-versa) instead of `OPEN_LO`/`OPEN_HI` sentinels.
+2. **No-match** via `Query.empty_query()` instead of the degenerate range. This also
+   fixes the cosmetic issue that the no-match sentinel always names the `created` field.
+3. **Retire the dead code**: remove the now-unused `_rewrite_*` helpers and the
+   `rewrite_natural_date_keywords` / `normalize_query` delegation shims in `_query.py`
+   (~160 lines left from the Phase-1 transition), and migrate their string-output tests
+   in `test_query.py` (replace the direct `_rewrite_compact_date` test with a
+   `translate_scalar` test).
+
+### Blocker
+
+Phase 2 is **gated on a published `tantivy-py` release**, not on any further code
+contribution. In `tantivy-py 0.26.0` (our current pin: `tantivy~=0.26.0` in
+`pyproject.toml`, released 2026-04-29), `range_query`/`term_query` **reject Python
+`datetime` values on `Date` fields** (`Expected DateTime type for field …`), so date
+Query objects cannot be built from Python. The fix is already merged on `tantivy-py`
+`master` across two PRs:
+
+- **#655** — `feat: support unbounded range queries via None bounds`.
+- **#666** — `fix: add_date loses tzinfo` (adds the `PyDateTime → tantivy DateTime`
+  converter and routes `range_query`/`term_query` through it).
+
+Both postdate the `0.26.0` wheel.
+
+- **Trigger:** a `tantivy-py` release `> 0.26.0` containing #655 + #666 is published to PyPI.
+- **Action:** bump the `tantivy-py` pin, then do items 1–3 above.
+
+## Out of scope
+
+- Unknown-field handling: Whoosh degraded an unknown `field:` to text; Tantivy 400s
+  (`http://x/a,b` → `Field does not exist: 'http'`). Not a date/comma/rename issue.
+- Whoosh fields with no Tantivy equivalent: `owner` (text), the `has_*` presence
+  booleans, `is_shared`, `custom_field_count`, `custom_fields_id`.
+- `>`/`<`/`>=`/`<=` comparisons — never supported in paperless-Whoosh (no `GtLtPlugin`).
+
+## Reference / how to re-verify
+
+- Tantivy side (does a translated string parse?): build a real index via
+  `documents.search._schema.build_schema` + `register_tokenizers`, then
+  `index.parse_query(translate_query(q, tz), DEFAULT_SEARCH_FIELDS, field_boosts=…)`.
+- Whoosh side (what did v2 do?): the old `get_schema()` + `MultifieldParser([...]) +
+DateParserPlugin(...)` still exists on `main` (`src/documents/index.py`); run a query
+  through it to get the ground-truth `Query`.
+- A fuller empirical gap matrix lives in `SEARCH_TANTIVY_WHOOSH_COMPAT.md`.

+# Bulk-Edit Operation Registry — Design
+
+**Date:** 2026-06-16
+**Branch base:** `dev`
+**Status:** Draft (rev. 2 — corrected per critical review)
+
+## Problem
+
+A single bulk-edit operation's definition is smeared across **eight sites in
+three files**, keyed **three different ways**, with no single source of truth.
+Taking `merge` as the worked example:
+
+| #   | Location                  | What it holds                                             | Keyed by              |
+| --- | ------------------------- | --------------------------------------------------------- | --------------------- |
+| 1   | `serialisers.py:1758`     | name in the `method` `ChoiceField.choices`                | **string**            |
+| 2   | `serialisers.py:1849`     | `validate_method` `elif` → returns `bulk_edit.merge`      | **string → function** |
+| 3   | `serialisers.py:2070`     | the `all=true`-unsupported list                           | **function identity** |
+| 4   | `serialisers.py:2115`     | `validate()` dispatch → `_validate_parameters_merge`      | **function identity** |
+| 5   | `serialisers.py:2008`     | `_validate_parameters_merge` (validate + coerce defaults) | —                     |
+| 6   | `views.py:2687`           | `METHOD_NAMES_REQUIRING_USER` / `_TRIGGER_SOURCE`         | **`__name__`**        |
+| 7   | `views.py:2727,2738,2754` | three permission blocks (`method in [...]`)               | **function identity** |
+| 8   | `views.py:2844`           | `MODIFIED_FIELD_BY_METHOD` audit field                    | **string**            |
+
+Plus the execution function itself in `bulk_edit.py`.
+
+Three structural problems follow:
+
+- **`validate_method` resolves the request string to a _function object_**
+  (`serialisers.py:1826-1860`), so everything downstream compares either
+  `method == bulk_edit.merge` (identity), `method.__name__` (string), or the raw
+  request string. Three keying schemes for one concept. Adding an operation — or
+  editing one — means touching all eight sites, and forgetting one fails
+  _silently_ (an op that runs but isn't audited, or skips an ownership check)
+  rather than loudly.
+
+- **The permission matrix is parameter-conditional and security-critical.** From
+  `views.py:2713-2760`: ownership is required for `merge`/`split` _only_ when
+  `delete_originals` is set; `add_document` is required for `edit_pdf`/
+  `remove_password` _only_ when `update_document` is not set; `delete_document`
+  for `merge`/`split` _only_ when `delete_originals`. This logic is correct but
+  lives far from the operations it governs, so it is hard to audit and easy to
+  break.
+
+- **The API is self-undocumenting.** `parameters` is a bare
+  `serializers.DictField` (`serialisers.py:1773`). drf-spectacular renders it as
+  a free-form object, so the OpenAPI schema tells a caller nothing about what
+  `merge` versus `set_correspondent` actually expect. The repo uses
+  `@extend_schema`/`inline_serializer` widely (62 sites) but has **no**
+  `PolymorphicProxySerializer`, `OpenApiExample`, or `discriminator` usage to
+  describe this polymorphic endpoint.
+
+## Goal
+
+Make each bulk-edit operation a **single object** that owns all eight facts —
+name, execution callable, parameter validation/coercion, audit field, the
+`all=`/single-document constraints, the user/trigger-source needs, and its
+parameter-conditional permission requirements. Operations live in a registry;
+the serializer and view consume the registry instead of re-encoding the
+operation list. Adding an operation becomes one class plus one registry entry,
+not an eight-site edit. As a deliberate, contract-preserving bonus, each
+operation also contributes a **per-operation request example** so the bulk API
+finally documents itself in the OpenAPI schema.
+
+**The wire contract does not change.** This is a relocation of internal logic,
+not a redefinition of the endpoint.
+
+## Scope
+
+In scope:
+
+- New `documents/bulk_operations.py` (registry + `BulkEditOperation` classes +
+  `PermissionRequirements`). The execution functions stay in `bulk_edit.py`;
+  operation classes wrap them.
+- Rewrite `BulkEditSerializer.validate_method` / `validate()` and the
+  `_validate_parameters_*` methods to delegate to the operation's parameter
+  serializer.
+- Rewrite `BulkEditView._has_document_permissions`, the `METHOD_NAMES_*` sets,
+  and `MODIFIED_FIELD_BY_METHOD` to read from the registry.
+- Add `examples=[...]` to the `bulk_edit` `@extend_schema`, generated from the
+  registry (one example per operation).
+- Unit tests per operation; keep every existing `test_api_bulk_edit*` test green.
+
+Out of scope:
+
+- Changing any operation's behavior, accepted method strings, parameter names,
+  defaults, coercion, or permission outcome. Byte-for-byte wire compatibility.
+- The legacy-method deprecation-warning machinery
+  (`MOVED_DOCUMENT_ACTION_ENDPOINTS`, the API-v9-drop TODO at `views.py:2855`):
+  legacy methods log a warning and process **inline** — there is **no** redirect
+  (`views.py:2856-2866`). Preserved as-is.
+- A full polymorphic request schema (`oneOf`/discriminated `parameters`). Examples
+  (option 1) are in scope; a discriminated schema is a possible future follow-up
+  and is **not** built here — the discriminator (`method`) and the variant
+  payload (`parameters`) are sibling fields, which `PolymorphicProxySerializer`
+  does not model cleanly. YAGNI until examples prove insufficient.
+- Converting `bulk_edit.py` into a package, or touching the execution functions'
+  internals.
+- Any third-party / entry-point registration of operations. The registry is
+  in-tree only; an entry point could be layered on later but the PDF/page ops are
+  tightly bound to internal helpers, so ecosystem value is low and unproven.
+
+## Decisions
+
+These shape the design and are the reviewable choices:
+
+1. **Operations wrap, not replace, the `bulk_edit.py` functions.** Each
+   `BulkEditOperation.execute` calls the existing function. The execution code is
+   correct and well-tested; this refactor is about the metadata and dispatch
+   around it, exactly as the export-sink refactor moved _plumbing_ without
+   touching export _contents_.
+2. **Parameter validation moves into a per-operation DRF `Serializer`**, not an
+   ad-hoc `clean_*` method. A real serializer (a) validates and coerces in one
+   place (replacing the `_validate_parameters_*` methods _and_ their in-place
+   mutation of defaults / the `pages`-string parse), (b) accepts `context`
+   (`user`, `documents`) for the cross-field/DB checks (page-bounds vs
+   `document.page_count`, documentlink targets, owner existence), and (c) is a
+   structure drf-spectacular already understands. Operations with no parameters
+   (`delete`, `reprocess`) declare `parameter_serializer_class = None`.
+3. **Permission requirements are computed by the operation, given the validated
+   parameters**, returning a `PermissionRequirements` value object. The
+   parameter-conditional kernel (ownership iff `delete_originals`, etc.) lives
+   next to the operation it governs. The view's three permission blocks collapse
+   to "build requirements, then check each flag generically."
+4. **Examples are derived from the registry** (option 1 from the design
+   discussion). Each operation declares a canonical `example_parameters` dict; a
+   helper builds one `OpenApiExample` per operation for the `bulk_edit`
+   `@extend_schema`. Adding an operation therefore auto-adds its example — the
+   examples cannot drift out of sync with the registry. This is the only piece
+   that _adds_ to the schema; it does not alter the request/response structure.
+5. **The registry is the single source of the method enum.** Today's enum is the
+   8 hardcoded field-ops (`serialisers.py:1758-1766`) plus
+   `LEGACY_DOCUMENT_ACTION_METHODS` — but the legacy methods (`delete, reprocess,
+rotate, merge, edit_pdf, remove_password, split, delete_pages`) **are
+   themselves operations**, not a disjoint set, so all **16 unique** methods live
+   in the registry. `ChoiceField.choices` is therefore
+   `list(BULK_EDIT_OPERATIONS)` **alone** — do NOT append
+   `LEGACY_DOCUMENT_ACTION_METHODS` (that would duplicate 8 entries and churn the
+   enum, the exact thing this decision prevents). The registry must be **ordered**
+   to reproduce today's member order — the 8 field-ops first (in
+   `serialisers.py:1758-1766` order), then the 8 legacy methods in
+   `MOVED_DOCUMENT_ACTION_ENDPOINTS` **key/insertion order** (`delete, reprocess,
+rotate, merge, edit_pdf, remove_password, split, delete_pages`;
+   `serialisers.py:1745-1754`) — so the generated OpenAPI `enum` is byte-identical.
+   NB: that legacy order is `edit_pdf, remove_password` _before_ `split,
+delete_pages` — do not reorder them.
+
+## Architecture
+
+### `PermissionRequirements`

+```
+
+### `BulkEditOperation`

+        SplitOperation(), DeletePagesOperation(),
+    )
+}
+```
+
+There is **no** `redo_ocr` entry. `validate_method` has a `method == "redo_ocr"`
+branch (`serialisers.py:1843`), but `"redo_ocr"` is absent from `choices`
+(`serialisers.py:1758-1768`), so the `ChoiceField` rejects it _before_
+`validate_method` runs — that branch is unreachable dead code today. Do **not**
+add `redo_ocr` to the registry: doing so would make it a valid `choices` entry
+and newly accept it on the wire (a contract change). `reprocess` is registered
+once, under `reprocess`.
+
+### How each call site collapses
+
+- **`ChoiceField.choices`** → `list(BULK_EDIT_OPERATIONS)` (the 16 unique
+  methods, registry ordered to match today). Legacy methods are already registry
+  ops, so they are **not** appended separately (see Decision 5).
+- **`validate_method`** → `return BULK_EDIT_OPERATIONS[method]` (the validated
+  value becomes an _operation object_ instead of a function — internal only,
+  `method` is `write_only`).
+- **`validate()`** → `op.clean_parameters(parameters, user=…, documents=…)`; the
+  `all=true` guard becomes `if attrs.get("all") and not op.supports_all: raise
+ValidationError("This method does not support all=true.")` (today's single
+  shared message, `serialisers.py:2077`, asserted verbatim by
+  `test_api_bulk_edit.py:763`); the per-method "only one document" checks become
+  an `op.max_documents` check that raises `op.too_many_documents_message`. That
+  text is **per-op** — "Split method only supports one document", "Delete pages
+  method only supports one document", "Edit PDF method only supports one document"
+  (`serialisers.py:2105,2111,2119`) — and is asserted verbatim (e.g.
+  `test_api_bulk_edit.py:1519`), so it **cannot** be collapsed to one generic
+  string.
+- **`METHOD_NAMES_REQUIRING_USER` / `_TRIGGER_SOURCE`** → `op.needs_user` /
+  `op.needs_trigger_source`.
+- **The three permission blocks** → one pass:
+  ```python
+  reqs = op.required_permissions(parameters)
+  ok = user.has_perm("documents.change_document") and all(
+      has_perms_owner_aware(user, "change_document", d) for d in document_objs
+  )
+  if ok and reqs.ownership:       ok = user_is_owner_of_all_documents
+  if ok and reqs.add_document:    ok = user.has_perm("documents.add_document")
+  if ok and reqs.delete_document: ok = user.has_perm("documents.delete_document")
+  ```
+- **`MODIFIED_FIELD_BY_METHOD`** → `op.audit_field`.
+
+**Two call sites consume this, not one.** `BulkEditView.post`
+(`views.py:2852-2947`) is a fully **inlined** path — it is the only path the
+`bulk_edit/` endpoint uses. It checks permissions, sets `user`/`trigger_source`,
+runs the audit-log block (`views.py:2896-2940`, currently keyed on
+`method.__name__` → becomes `op.audit_field`), and calls `method(documents,
+**parameters)`. `_execute_document_action` (`views.py:2764-2807`) is a
+**separate** path used by the _moved single-action_ endpoints
+(`/api/documents/delete/`, `/rotate/`, …); it builds `parameters`, sets
+user/trigger, and checks permissions independently and has **no** audit logging.
+The refactor must convert **both** to the registry; audit logging stays only in
+`post`.
+
+## Operation inventory (the faithful matrix)
+
+Compiled from `bulk_edit.py` signatures, `serialisers.py:2067-2126`, and
+`views.py:2679-2760`. `change` is required for every operation and omitted.
+`[source_mode]` is the shared optional param accepted by the PDF-touching ops
+(validated by `_validate_source_mode` only when present).

+
+Notes that are easy to get wrong and are pinned here:
+
+- `edit_pdf` ownership is **unconditional** — it is in the unconditional
+  ownership list (`views.py:2722`); the separate `edit_pdf and update_document`
+  clause (`views.py:2730`) is redundant and folds away.
+- `remove_password` **does** accept an `update_document` param
+  (`bulk_edit.py:881`), and `parameters` is a passthrough `DictField` whose
+  validator (`serialisers.py:2061-2065`) neither strips nor defaults it. So its
+  `add_document` requirement is `not parameters.get("update_document", False)` —
+  identical to `edit_pdf`, **not** an unconditional `True`. Sending
+  `update_document: true` legitimately drops the add_document requirement today,
+  and that behavior must be preserved. (Earlier drafts claimed the param did not
+  exist — that was a permission-correctness bug.)
+- `merge` and `remove_password` are **not** single-document (no `max_documents`),
+  even though both set `supports_all = False`.
+
+## Parameter coercion contract to preserve
+
+`clean_parameters` must reproduce every in-place coercion the current
+`_validate_parameters_*` methods perform, not merely the validation. Full list
+(an implementation-plan checklist):
+
+- `merge` / `split`: default `delete_originals=False`
+  (`serialisers.py:1998,2013`); `merge` also defaults `archive_fallback=False`
+  (`:2018`).
+- `edit_pdf`: default `update_document=False`, `include_metadata=True`
+  (`:2038,2043`); reject `update_document=True` with multiple output docs
+  (`:2045-2050`).
+- `set_permissions`: default `merge=False` (`:1951-1952`) and **mutate**
+  `parameters["set_permissions"]` in place via `validate_set_permissions`
+  (`:1946`, `SetPermissionsMixin`); validate `owner` existence
+  (`:1939-1943,1949-1950`). Needs its own `SetPermissionsParametersSerializer`.
+- `split`: parse the `pages` string `"1-3,5"` → `[[1,2,3],[5]]` (`:1974-1990`).
+- `source_mode`: validated and applied **only when present** in `parameters`
+  (`:2084-2085` gate → `validate_source_mode`, `:1964-1969`), independent of
+  method — so each PDF-touching op's serializer opts into it conditionally.
+- `modify_custom_fields`: accept **list OR `{id: value}` dict**, and for
+  DOCUMENTLINK fields validate targets via `validate_documentlink_targets`
+  (`:1787-1824`).
+- **Param-name spelling differs by op** and must match exactly: `merge`/`split`
+  use `delete_originals` (plural); `edit_pdf`/`remove_password` use
+  `delete_original` (singular) (`bulk_edit.py:509,619,751,882`).
+
+## OpenAPI examples (the "make it useful" piece)
+
+A single helper builds the examples from the registry:
+
+```python
+def _bulk_edit_examples() -> list[OpenApiExample]:
+    return [
+        OpenApiExample(
+            name=op.name,
+            summary=op.name,
+            value={"documents": [1, 2], "method": op.name,
+                   "parameters": op.example_parameters},
+            request_only=True,
+        )
+        for op in BULK_EDIT_OPERATIONS.values()
+    ]
+```
+
+wired into the existing decorator (the response schema at `views.py:2818-2825`
+is untouched):
+
+```python
+@extend_schema_view(
+    post=extend_schema(
+        operation_id="bulk_edit",
+        description="Perform a bulk edit operation on a list of documents",
+        examples=_bulk_edit_examples(),
+        responses={200: inline_serializer(name="BulkEditDocumentsResult",
+                                          fields={"result": serializers.CharField()})},
+    ),
+)
+```
+
+Result: the Swagger/Redoc page shows a concrete, valid request body for every
+operation (`merge`, `edit_pdf`, …), generated from the same objects that
+validate the request — they cannot drift apart. The request _structure_
+(`{documents, method, parameters, …}`) and the `method` `enum` are unchanged;
+examples are purely additive.
+
+## Data flow
+
+```
+POST /api/documents/bulk_edit/  {documents|all|filters, method, parameters, from_webui}
+  ├─ legacy method? → log deprecation warning, then process INLINE  (no redirect; views.py:2856-2866)

+       └─ if op.audit_field and AUDIT_LOG_ENABLED: LogEntry per doc → Response({"result": …})
+note: _execute_document_action (views.py:2764-2807) is the SEPARATE moved-single-action path
+      (/api/documents/delete/, /rotate/, …); it converts to the registry too, but has NO audit log.
+      audit "reason" string uses op.name (== bulk_edit.<fn>.__name__ today, so unchanged at runtime).
+```
+
+## Backwards compatibility
+
+- **Wire contract:** request/response shapes, accepted `method` strings,
+  parameter names, defaults, coercion, and every permission outcome are
+  byte-for-byte preserved. `method` becoming an operation object is internal
+  (`write_only`).
+- **`bulk_edit.<fn>` patching keeps working — by module identity, not luck.**
+  Existing tests patch `documents.serialisers.bulk_edit.<fn>` and
+  `documents.views.bulk_edit.<fn>` (e.g. `test_api_bulk_edit.py:203,485,1100,1271`).
+  All of `documents.serialisers.bulk_edit`, `documents.views.bulk_edit`, and the
+  new `documents.bulk_operations.bulk_edit` are the **same module object** in
+  `sys.modules`; patching an attribute via any path mutates the one shared module.
+  So as long as each `op.execute` does a **call-time** lookup
+  (`return bulk_edit.merge(doc_ids, **kw)`, not a function captured at
+  class-definition time), the existing patches still intercept and those tests
+  stay untouched.
+- **The `method.__name__` dependency disappears.** `setup_mock`
+  (`test_api_bulk_edit.py:61-63`) sets `m.__name__` because dispatch reads
+  `method.__name__` (`views.py:2783,2879,2896,2938`). The refactor replaces every
+  such read with `op.name` / `op.needs_user` / `op.audit_field`, so the mock's
+  `__name__` no longer affects dispatch. The audit "reason" becomes
+  `f"Bulk edit: {op.name}"`; since `bulk_edit.merge.__name__ == "merge" ==
+op.name`, real-run audit text is unchanged. No test asserts
+  `validated_data["method"]` identity (verified), so `validate_method` returning
+  an operation object is safe.
+- **Legacy methods:** `MOVED_DOCUMENT_ACTION_ENDPOINTS` /
+  `LEGACY_DOCUMENT_ACTION_METHODS` and the v9-drop TODO are unchanged. They drive
+  only the inline deprecation warning (`views.py:2856-2866`), **not** the
+  `choices` — which come wholly from the registry, since the legacy methods _are_
+  registry ops (see C1/Decision 5).
+- **OpenAPI:** the `method` `enum` and request/response structure are unchanged
+  (Decision 5); `examples` are additive. Regenerated schema diff should be
+  _examples only_.
+
+## Testing
+
+New `documents/tests/test_bulk_operations.py` (pytest classes, factory-boy
+factories, the `mocker` fixture, `parametrize`, full type annotations; run on the
+Linux VM):
+
+- **Permission matrix, parametrized over every operation** — the highest-value
+  test. For each op and each relevant parameter combination
+  (`delete_originals` on/off, `update_document` on/off), assert
+  `op.required_permissions(params)` equals the expected
+  `PermissionRequirements`. This freezes the security kernel against drift.
+- **Registry/serializer parity** — `ChoiceField.choices` equals the **16 unique**
+  method strings in today's exact order (8 field-ops, then the 8
+  `MOVED_DOCUMENT_ACTION_ENDPOINTS` keys); **no duplicates**; `redo_ocr` absent;
+  every method resolves to an operation. (Guards against the C1 duplication bug.)
+- **Parameter validation/coercion** per op — defaults applied (`merge` →
+  `delete_originals=False`, `archive_fallback=False`; `split`/`edit_pdf` defaults),
+  the `pages` string→list parse, page-bounds-vs-`page_count`, documentlink target
+  and owner-existence checks — mirroring the current `_validate_parameters_*` tests.
+- **`supports_all` / `max_documents`** — `all=true` rejected for the five
+  no-all ops; `>1` document rejected for `split`/`delete_pages`/`edit_pdf`.
+- **Examples** — `_bulk_edit_examples()` yields one entry per distinct operation,
+  each `value["parameters"]` validates clean through that op's
+  `parameter_serializer_class` (guarantees documented examples are valid).
+
+Existing `test_api_bulk_edit.py` / `test_api_bulk_download.py` stay green
+unchanged — external behavior (accepted methods, validation errors, permission
+403s, audit fields, results) is preserved.
+
+## Risks
+
+- **Permission-matrix mistranslation is a privilege-escalation bug, not a
+  cosmetic one.** This is the whole ballgame. Mitigation: move the logic verbatim
+  into per-op `required_permissions`, and the parametrized permission test above
+  is written _first_ against the current behavior, then held invariant across the
+  refactor.
+- **The `method`-as-function-object contract** is relied on by existing tests
+  (identity compares, `bulk_edit.<fn>` patching). Mitigation: keep `execute`
+  delegating to the module-level function so patches still bite; adjust only the
+  identity asserts. Audit `test_api_bulk_edit.py` before coding.
+- **Serializer-based validation subtly changing error messages/shapes.** The
+  current validators raise specific `ValidationError` strings that tests assert
+  on. Mitigation: preserve message text when porting each `_validate_parameters_*`
+  into its serializer; diff the test expectations.
+- **Enum churn in the generated schema.** Mitigation: Decision 5 fixes member set
+  and order; the schema-diff check in CI should show examples-only changes.

+# Export Sink Architecture — Design
+
+**Date:** 2026-06-16
+**Branch base:** `dev`
+**Status:** Approved design, pending implementation plan
+
+## Problem
+
+The `document_exporter` management command can export to a folder or to a zip
+file, but the zip support is bolted on rather than designed in:
+
+- **Zip mode is a temp-dir detour.** `handle()` redirects `self.target` to a
+  `tempfile.TemporaryDirectory` in `SCRATCH_DIR`, runs the entire export against
+  that directory, then calls `shutil.make_archive` to zip the whole tree and
+  cleans the temp dir up (`document_exporter.py:322-358`). The export is written
+  to disk twice (loose files, then the zip).
+
+- **An attempted "direct to zip" refactor leaks the destination everywhere.**
+  The prior work on `feature-direct-zip-export` threads `if self.zip_export:`
+  branches through `check_and_copy`, `check_and_write_json`,
+  `_write_split_manifest`, `dump`, `handle`, and `StreamingManifestWriter`. Each
+  write site grew a second code path plus a `.resolve().relative_to(self.target)`
+  arcname dance. The destination became a cross-cutting concern smeared across
+  the command.
+
+- **The command owns logic that isn't about the export contents.** Incremental
+  sync — the `files_in_export_dir` snapshot, the `--compare-checksums` /
+  `--compare-json` skip-if-unchanged checks, and the `--delete` stale-file prune —
+  is interleaved with the logic that decides _what_ to export. These behaviors
+  only make sense for a folder destination, yet they live in the command body.
+
+- **Atomicity is informal.** A backup must never look complete when it isn't.
+  The temp-dir approach happens to be safe (the zip is built last), but there is
+  no explicit "produce the archive only if the whole run succeeded" contract, and
+  the direct-to-zip branch had to hand-manage a `.tmp` file inline.
+
+## Goal
+
+Separate **what** is exported (the command's job) from **where/how** it lands
+(the destination's job), behind a small `ExportSink` abstraction. The command
+declares files, JSON blobs, and a streamed manifest; the sink decides whether and
+how to persist each one. Folder and zip become two interchangeable sinks, and a
+future `S3ExportSink` is a third implementation rather than a fourth set of
+branches. The zip is produced **only** if the entire export succeeds.
+
+## Scope
+
+In scope:
+
+- New `documents/export/` package with the `ExportSink` ABC and two concrete
+  sinks (`DirectoryExportSink`, `ZipExportSink`).
+- Move all incremental-sync machinery (snapshot, compare, prune) out of the
+  command and into `DirectoryExportSink`.
+- Rewrite `document_exporter.handle()` / `dump()` to be destination-agnostic.
+- Simplify `StreamingManifestWriter` to write to a sink-provided handle.
+- Unit tests for each sink; keep existing command-level tests green.
+
+Out of scope:
+
+- `bulk_download.py` / `BulkArchiveStrategy` and share-link bundle zipping. Those
+  select _which document files_ go in and stream to an HTTP response with no
+  atomic-finalize requirement — a different axis from the backup sink. Untouched.
+- Actually implementing an S3 (or any cloud) sink. The interface is designed to
+  _allow_ one; we do not build one (YAGNI).
+- Changing the export's on-disk/in-zip layout, manifest schema, crypto, or any
+  CLI flag's meaning. Behavior is preserved; only the destination plumbing moves.
+- Zip compression control (method / level). The `ZipExportSink` keeps today's
+  fixed `ZIP_DEFLATED` here; making compression configurable is a follow-up —
+  see `2026-06-16-export-zip-compression-design.md`, which depends on this
+  refactor landing first. The sink is the single seam that makes it a small,
+  isolated change.
+
+## Decisions
+
+These were settled during brainstorming:
+
+1. **Scope is the `document_exporter` command only.** Design the interface so an
+   S3 sink could be added later; do not refactor `bulk_download` or share bundles.
+2. **`--compare-*` are folder-only (hard error with `--zip`); `--delete` is kept
+   for both.** `--compare-checksums` / `--compare-json` are genuine no-ops in zip
+   mode today (the temp dir is always empty, so the compare always copies), so
+   combining either with `--zip` raises a `CommandError` up front. **`--delete`,
+   however, is an existing tested feature in zip mode** — it wipes the destination
+   directory of pre-existing files/dirs before the archive lands
+   (`test_export_zipped_with_delete`). Its meaning differs by destination: folder
+   `--delete` prunes stale exported files; zip `--delete` clears the target dir.
+   Both are preserved — `--delete` is a parameter of _both_ sinks, not an error.
+3. **The zip manifest spools to a temp file, not memory.** The sink exposes a
+   streaming-write handle. The zip sink streams the manifest to a single temp
+   file in `SCRATCH_DIR` and adds it as the manifest entry at finalize, keeping
+   peak memory flat regardless of library size. The only "temp" artifact is one
+   manifest file, not a whole export tree.
+
+## Architecture
+
+### The `ExportSink` interface
+
+New module `documents/export/sinks.py`:
+
+```python
+class ExportSink(AbstractContextManager):
+    """Destination for a document export.
+
+    The command declares export contents via the three verbs below; the sink
+    decides whether and how to persist each item. arcname is always a relative
+    POSIX path (e.g. "manifest.json", "originals/foo.pdf").
+    """
+
+    def add_file(
+        self,
+        source: Path,
+        arcname: str,
+        *,
+        checksum: str | None = None,
+    ) -> None:
+        """Persist an existing file at the relative arcname."""
+
+    def add_json(self, content: list | dict, arcname: str) -> None:
+        """Persist JSON-serializable content at the relative arcname."""
+
+    def stream(self, arcname: str) -> ContextManager[TextIO]:
+        """Yield a writable text handle for incrementally produced content.
+
+        Reserved for the bulk manifest. At most one stream may be open at a
+        time; add_file/add_json may be called freely while it is open.
+        """
+
+    # __enter__ opens the sink and returns self.
+    # __exit__ calls finalize() on success, abort() on exception.
+```
+
+**Contract / invariants** (the checklist a future sink author honors):
+
+- `arcname` is relative and **POSIX-style (forward slashes)**; the sink maps it to
+  its own namespace (folder: joined under the target; zip: the entry name). The
+  command must build arcnames with `Path(...).as_posix()` — `str(Path(...))`
+  yields backslashes on Windows, which corrupts zip entry names and makes the
+  manifest's stored paths non-portable. The same string is used both as the sink
+  key and as the value stored in the manifest (`EXPORTER_FILE_NAME` etc.), so it
+  must be POSIX at the point of construction. (The share-link bundle path already
+  uses `.as_posix()`; the document targets currently do not and must be fixed.)
+- At most one `stream()` is open at a time. It is the manifest. `add_file` /
+  `add_json` may be interleaved with an open stream — implementations that can't
+  interleave a real stream (zip, S3) must spool the stream to a side buffer and
+  emit it at `finalize()`.
+- The sink is a context manager. Normal exit finalizes; an exception aborts.
+  **No partial or failed run may leave a "complete-looking" artifact.**
+
+### `DirectoryExportSink(target, *, compare_checksums, compare_json, delete)`
+
+Owns everything the command currently does for folder mode:
+
+- On open: snapshot existing files under `target` (today's `files_in_export_dir`).
+- `add_file`: the `check_and_copy` skip logic (mtime/size, or checksum when
+  `compare_checksums`), then copy with stat preservation. Records the arcname as
+  "seen this run".
+- `add_json`: the `check_and_write_json` blake2b compare-or-write (honoring
+  `compare_json`). Records the arcname as seen.
+- `stream`: yields a handle writing to `<arcname>.tmp`; on context close, applies
+  the `compare_json` blake2b compare and renames-or-discards (today's
+  `StreamingManifestWriter` finalize). Records the arcname as seen.
+- `finalize()` (success only): if `delete`, prune every snapshot file not seen
+  this run and clean up emptied directories (today's stale-delete pass).
+- `abort()` (on exception): discard any in-flight `.tmp`; leave existing files
+  intact; do **not** run the prune.
+
+The folder sink is inherently in-place/incremental, not atomic — that is its
+nature and is unchanged. Its safety is the per-file `.tmp`+rename it already does.
+
+### `ZipExportSink(target, zip_name, *, delete)`
+
+- On open: ensure `SCRATCH_DIR` exists (`mkdir(parents=True, exist_ok=True)` —
+  today's `handle()` does this before using it; the sink must do it now), then
+  open a `zipfile.ZipFile` at `<target>/<zip_name>.zip.tmp` (`ZIP_DEFLATED`,
+  `allowZip64=True`). The `.zip.tmp` lives in the same directory as the final
+  `.zip` so the finalize rename is atomic (same filesystem).
+- `add_file` / `add_json`: write the entry directly, first emitting directory
+  marker entries for parent paths so every zip viewer shows the folder structure
+  (today's `_ensure_zip_dirs`). A _flat_ export (no `--use-folder-prefix`, no
+  nested arcnames) has no parent dirs, so it emits **zero** markers — matching
+  today's `make_archive` output for flat trees (keeps the `namelist()` count
+  assertions in `test_export_zipped` valid). Nested/prefixed exports gain marker
+  entries; any count assertion on those must be audited.
+- `stream`: yields a handle writing to a single temp file in `SCRATCH_DIR`.
+- `finalize()` (success only): add the spooled manifest temp file as its entry,
+  close the zip, then **if `delete`, wipe the destination directory** of every
+  pre-existing file/dir except the in-progress `.zip.tmp` and any prior `.zip`
+  (today's zip `--delete` behavior), then atomically rename `.zip.tmp` → `.zip`.
+- `abort()` (on exception): close the zip, unlink the `.zip.tmp`, delete the
+  manifest temp file. **A `.zip` therefore exists only after a fully successful
+  run**, and on abort the destination is never wiped.
+- Rejects `compare_*` (the command guards this before constructing the sink). It
+  does **not** reject `delete` — that is a supported zip behavior (see above).
+
+### Command changes (`document_exporter.py`)
+
+- **`handle()`**: validate the target, then _up front_ raise `CommandError` if
+  `--compare-checksums` or `--compare-json` is combined with `--zip` (those are
+  no-ops in zip mode). `--delete` is **not** rejected — it is passed to whichever
+  sink is built. Construct the appropriate sink (`delete=` passed to both). Run
+  the export as `with sink: self.dump(sink)`. Delete the temp-dir /
+  `shutil.make_archive` block entirely.
+- **`--data-only`**: unchanged in meaning — it simply skips every `sink.add_file`
+  call (no document/thumbnail/archive/bundle files) while the manifest stream and
+  `metadata.json` are still written. Works identically for both sinks; no sink
+  code is data-only-aware. (`test_export_data_only` and its zip equivalent stay
+  green.)
+- **`dump(sink)`**: destination-agnostic. Builds relative arcnames and calls
+  `sink.add_file(...)`, `sink.add_json(...)`, and `sink.stream("manifest.json")`.
+  `self.files_in_export_dir`, `check_and_copy`, `check_and_write_json`, and the
+  stale-delete pass are removed (their logic now lives in the folder sink).
+- **`generate_document_targets`**: returns relative arcnames
+  (`originals/<name>`, `<name>-thumbnail.webp`, `archive/<name>-archive.pdf`)
+  instead of absolute `self.target / ...` paths. It already writes the relative
+  name into `document_dict[EXPORTER_FILE_NAME]` etc.; we just drop the absolute
+  half.
+- **`StreamingManifestWriter`**: simplified to write JSON-array records to the
+  text handle returned by `sink.stream("manifest.json")`. It no longer knows
+  folder vs zip, owns no `.tmp` logic, and has no compare/zip parameters — that
+  behavior moved into each sink's `stream()`.
+- **Crypto / passphrase** handling stays in the command: it transforms record
+  _contents_ before they reach the sink, which is independent of destination.
+- **Progress tracking stays in the command — the sinks know nothing about it.**
+  `PaperlessCommand.track()` wraps the _document iterable_ in `dump()` and ticks
+  the Rich bar once per document. That loop stays in the command; each iteration
+  calls `sink.add_file(...)`, so the per-document progress is preserved
+  unchanged. The sinks deliberately do **not** depend on `PaperlessCommand`,
+  `track()`, or Rich — coupling the destination abstraction to the command
+  framework would defeat the isolation goal and make the sinks impossible to unit
+  -test without a full command. (A sink is a plain context-managed I/O object; it
+  is constructed by `handle()` and exercised directly in `test_sinks.py`.) If
+  finer-grained progress is ever wanted for a single very large file, that is a
+  future enhancement layered via an optional callback — not a `PaperlessCommand`
+  dependency, and out of scope here.
+
+### How `--split-manifest` fits (no sink special-casing)
+
+`--split-manifest` is purely a command-level choice and touches no sink code:
+
+- The single bulk `manifest.json` is always the one and only `sink.stream(...)`
+  handle. In split mode it simply carries fewer record types (document records,
+  notes, and custom-field-instances are redirected out).
+- Per-document `<base>-manifest.json` files are small _complete_ JSON blobs — they
+  were never streamed. `_write_split_manifest` collapses to building the content
+  list and one `sink.add_json(content, "<base>-manifest.json")` call, exactly
+  like `metadata.json`.
+
+Because the manifest stream is backed by its own handle (a `.tmp` file in the
+folder sink, a `SCRATCH_DIR` temp file in the zip sink) and never an open zip
+entry, the per-document `add_json` / `add_file` calls made _while the bulk
+manifest stream is open_ never collide with it.
+
+## Data flow
+
+```
+handle(options)
+  ├─ validate target; reject --compare-* + --zip  → CommandError  (--delete allowed)
+  ├─ sink = DirectoryExportSink(..., delete=…) | ZipExportSink(..., delete=…)
+  └─ with FileLock(MEDIA_LOCK), sink:
+       dump(sink)
+         ├─ with sink.stream("manifest.json") as mh:
+         │    writer = StreamingManifestWriter(mh)
+         │    ├─ global querysets        → writer.write_batch(...)   (encrypted inline)
+         │    ├─ per document:
+         │    │    ├─ sink.add_file(source, "originals/…", checksum=…)
+         │    │    ├─ sink.add_file(thumb,  "…-thumbnail.webp")
+         │    │    ├─ sink.add_file(archive,"archive/…-archive.pdf", checksum=…)
+         │    │    └─ split? sink.add_json(doc_bundle, "…-manifest.json")
+         │    │            : writer.write_record(doc_record)
+         │    └─ per share-link bundle: sink.add_file(...) + writer.write_record(...)
+         └─ sink.add_json(metadata, "metadata.json")
+  (success → sink.finalize();  exception → sink.abort())
+```
+
+## Error handling & atomicity
+
+- Any exception in `dump()` propagates through `with sink:` → `__exit__` →
+  `abort()`. Zip: the `.zip.tmp` and the manifest temp file are deleted, and the
+  destination is **not** wiped; **no `.zip` is produced.** Folder: in-flight
+  `.tmp` files are discarded, existing files are left intact, and the stale-prune
+  does not run.
+- `finalize()` runs only on clean exit, after all contents are written. For the
+  zip: optionally wipe the destination (`--delete`), then the single `.zip.tmp` →
+  `.zip` rename (atomic on the same filesystem). For the folder: the optional
+  stale-delete prune.
+- **Honest limits of the atomicity guarantee.** The guarantee is "no
+  _complete-looking_ `.zip` after a failed run," not "no leftovers." If the
+  process is `SIGKILL`ed or the rename itself fails _after_ the zip is closed, a
+  `.zip.tmp` may be orphaned — that is the safe direction (no false-complete
+  `.zip`), but stale `.zip.tmp` files are **not** auto-cleaned on a later run
+  (matching the prior branch). `KeyboardInterrupt` is a `BaseException` but
+  `__exit__` still runs, so `abort()` fires normally. The rename being atomic and
+  these runs not racing each other both rely on `FileLock(settings.MEDIA_LOCK)`,
+  which serializes exports; concurrent same-`--zip-name` runs are out of scope.
+- The `FileLock(settings.MEDIA_LOCK)` wrapping is unchanged.
+
+## Testing
+
+New `documents/export/tests/test_sinks.py`, unit-testing each sink in isolation
+(pytest classes, factory-boy factories, the `mocker` fixture, `parametrize`, full
+type annotations; run on the Linux VM):
+
+- **Round-trip** (both sinks, parametrized): `add_file` + `add_json` + a streamed
+  manifest produce the expected files/entries with correct relative arcnames.
+- **Folder incremental**: unchanged file is skipped under `compare_checksums` and
+  under `compare_json`; `delete` prunes a snapshot file not written this run and
+  removes emptied directories; without `delete`, stale files remain.
+- **Zip atomicity**: injecting an exception mid-export (via `mocker`) leaves no
+  `.zip` and no leftover `.zip.tmp`, and does not wipe the destination even with
+  `--delete`; a clean run yields exactly the `.zip`. A nested/prefixed export has
+  directory marker entries; a flat export has none.
+- **Zip `--delete`**: a clean `--zip --delete` run wipes pre-existing
+  files/dirs in the destination and produces the `.zip` (preserves
+  `test_export_zipped_with_delete`).
+- **POSIX arcnames**: nested arcnames are stored with forward slashes in both the
+  zip entry names and the manifest values, regardless of host OS (guards the
+  Windows backslash bug).
+- **`--data-only`**: both sinks produce only `manifest.json` + `metadata.json`,
+  no document files.
+- **Stream contract**: opening a second concurrent `stream()` is rejected;
+  `add_file`/`add_json` while a stream is open succeed.
+- **Command guard**: `--zip` with `--compare-checksums` or `--compare-json`
+  raises `CommandError`; `--zip --delete` does **not** error.
+
+Existing `test_management_exporter.py` and `test_management_importer.py` stay
+green unchanged — the export's external behavior (layout, manifest, round-trip
+import, `--zip --delete`, `--data-only`) is preserved.
+
+## Risks
+
+- **Behavior drift in the folder path.** The incremental logic is subtle
+  (mtime/size vs checksum, blake2b json compare, empty-dir cleanup). Mitigation:
+  move it verbatim into the sink and lean on the unchanged command-level tests
+  plus new focused sink tests.
+- **Manifest interleaving in zip mode.** Relies on the spool-to-temp-file
+  decision; the stream contract makes this explicit and the stream-contract test
+  guards it.

+# Export Zip Compression Control — Design
+
+**Date:** 2026-06-16
+**Branch base:** `dev`
+**Status:** Design complete (zstd facts verified on CPython 3.14.3) — **depends on**
+`2026-06-16-export-sink-architecture-design.md` being implemented first.
+
+## Prerequisite
+
+This builds directly on the export sink refactor. It assumes `ZipExportSink`
+already exists and is the single place that owns `zipfile.ZipFile` creation and
+entry writes. Do not start this until that refactor has landed; without it, the
+change would have to touch the command's zip branches again.
+
+## Problem
+
+Zip export is hardwired to `ZIP_DEFLATED` at the library default level. Users
+have no way to trade speed against archive size — a fast `ZIP_STORED` pass for a
+quick local copy, or a maximal `ZIP_LZMA` pass for the smallest off-site backup.
+The sink refactor turns "which compression" into a single constructor argument,
+so exposing it is now a small, isolated change.
+
+## Goal
+
+Let the operator choose the zip compression method and level from the CLI, with
+behavior identical to today when the flags are omitted. All knowledge of
+compression stays inside `ZipExportSink`; the command only parses flags and maps
+them to sink arguments.
+
+## Scope
+
+In scope:
+
+- `ZipExportSink` gains `compression: int` and `compresslevel: int | None`
+  constructor parameters (default `ZIP_DEFLATED`, `None` → library default),
+  passed straight to `zipfile.ZipFile(...)`.
+- New `document_exporter` flags: `--zip-compression` and
+  `--zip-compression-level`, valid only with `--zip`.
+- Validation: method availability, level range per method, and the
+  requires-`--zip` guard.
+- Import-side: a pre-extract support check in `document_importer` that turns an
+  unsupported codec into a clear `CommandError` (the importer otherwise decompresses
+  transparently via `ZipFile.extractall`).
+- Docs: add both flags and the zstd-portability caveat to `docs/administration.md`
+  (the `document_exporter` option list, lines ~257-270 and the `-z`/`-zn` section,
+  lines ~328-330). New flags are long-form only (`--zip-compression`,
+  `--zip-compression-level`) — no short aliases, to avoid `-zc`/`-zl` collisions
+  with the existing `-z`/`-zn`.
+
+Out of scope:
+
+- Compression for any non-zip sink (folder has none; a future S3 sink would
+  handle its own object storage compression separately).
+- Changing the default. Omitting the flags must produce a byte-compatible-method
+  archive to today's (`ZIP_DEFLATED`, default level).
+
+## Design
+
+### `ZipExportSink` changes
+
+The base sink's signature is `ZipExportSink(target, zip_name, *, delete)`; this
+adds two keyword-only params after `delete`:
+
+```python
+def __init__(
+    self,
+    target: Path,
+    zip_name: str,
+    *,
+    delete: bool = False,
+    compression: int = zipfile.ZIP_DEFLATED,
+    compresslevel: int | None = None,
+) -> None:
+    ...
+    # opened in __enter__:
+    self._zip = zipfile.ZipFile(
+        self._tmp_path,
+        "w",
+        compression=compression,
+        compresslevel=compresslevel,
+        allowZip64=True,
+    )
+```
+
+`ZipFile` applies `compression`/`compresslevel` as the default for every
+`write`/`writestr` (verified: a `ZipFile(..., compression=ZIP_BZIP2)` yields
+entries with `compress_type == ZIP_BZIP2` without per-call args), so `add_file` /
+`add_json` / the manifest entry need no changes. Directory marker entries are
+empty so their compressed payload is zero, but they are still _tagged_ with the
+chosen `compress_type` — harmless, but tests that read `infolist()` should filter
+or account for marker entries (see Testing).
+
+### CLI flags (`document_exporter`)
+
+- `--zip-compression {stored,deflated,bzip2,lzma}` — and `zstd` **when the
+  runtime supports it** (see below). Maps to the matching `zipfile.ZIP_*`
+  constant. Default `deflated`.
+- `--zip-compression-level N` — integer. Per-method accepted ranges (verified
+  against the [3.14 `zipfile` docs](https://docs.python.org/3.14/library/zipfile.html#zipfile.ZipFile)):
+  - `deflated`: **0–9** (`zlib` also accepts `-1` = "default", identical to
+    omitting the flag / `compresslevel=None`).
+  - `bzip2`: **1–9** (`0` is invalid for bzip2).
+  - `lzma`, `stored`: level has **no effect** — passing `--zip-compression-level`
+    with either is a `CommandError`, not a silent accept (consistent with the
+    base refactor's fail-fast posture).
+  - `zstd`: **-131072 … 22** (the documented commonly-accepted range; the
+    authoritative bounds are
+    `compression.zstd.CompressionParameter.compression_level.bounds()`).
+
+  Default: unset → library default (`compresslevel=None`).
+
+Both flags require `--zip`; passing either without `--zip` raises a
+`CommandError`, matching the incremental-flag rule from the base refactor.
+
+**Why validate up front (not let `zipfile` raise) — verified on 3.14.3:** an
+invalid level does _not_ fail at `ZipFile(...)` construction — it fails at the
+**first `write`/`writestr` call**, with an opaque message
+(`ValueError: Invalid initialization option` for deflated > 9, or
+`ValueError: compresslevel must be between 1 and 9` for bzip2). Worse, on context
+exit the half-initialized write handle emits a secondary
+`AttributeError: '_ZipWriteFile' object has no attribute '_compressor'` during GC
+finalization, so the user sees stack-trace noise unrelated to the real cause.
+Up-front validation turns all of that into a single clean `CommandError`.
+
+### Validation (in `handle()`, before constructing the sink)
+
+1. **Requires `--zip`.** Either flag without `--zip` → `CommandError`.
+2. **Method availability — via a named, patchable seam.** Expose a module-level
+   helper `compression_available(method: str) -> bool` that does
+   `try: import bz2 / import lzma / from compression import zstd except ImportError:
+return False` — **not** `importlib.util.find_spec`, which can report a stdlib
+   C-extension as present when importing it actually fails. `stored`/`deflated`
+   are always available (`zlib` is a hard CPython dependency). For `zstd` the probe
+   must import `compression.zstd` (3.14+), not merely check that
+   `zipfile.ZIP_ZSTANDARD` exists. Making this a named function is also what lets
+   the test patch "method unavailable" with `mocker`. If the chosen method is
+   unavailable, raise a `CommandError` naming the missing capability — `zipfile`
+   itself would otherwise raise a bare `RuntimeError`
+   ("Compression requires the (missing) … module").
+3. **Level range.** Reject an out-of-range `--zip-compression-level` for the
+   chosen method with a clear `CommandError`; reject the flag entirely for
+   `stored`/`lzma` (see above).
+
+### zstd (Python 3.14+)
+
+**Verified empirically on CPython 3.14.3** (via `uv run --python 3.14 --no-project`)
+and against [PEP 784](https://peps.python.org/pep-0784/) +
+[the 3.14 `zipfile` docs](https://docs.python.org/3.14/library/zipfile.html):
+
+- The compression-method constant is **`zipfile.ZIP_ZSTANDARD`** (added 3.14; its
+  numeric value is `93`). It does **not** exist on < 3.14.
+- It is backed by the new **`compression.zstd`** stdlib module (PEP 784 added a
+  `compression` namespace package; legacy `bz2`/`lzma`/`zlib` imports are
+  unchanged). `zipfile` raises `RuntimeError` if `compression.zstd` is
+  unavailable when zstd is requested.
+- Accepted `compresslevel` is **`-131072 … 22`**, confirmed at runtime via
+  `compression.zstd.CompressionParameter.compression_level.bounds() == (-131072, 22)`.
+
+Gate everything zstd-related at runtime so nothing is imported or referenced on
+< 3.14 (the project targets Python ≥ 3.11):
+
+```python
+_ZSTD: int | None = getattr(zipfile, "ZIP_ZSTANDARD", None)  # None before 3.14
+```
+
+Presence of the _constant_ does not guarantee the _codec_ is usable, so the
+availability probe (validation step 2) imports `compression.zstd`, not merely
+checks the constant.
+
+Keep `zstd` in the `--zip-compression` `choices` **always** (even on < 3.14), and
+reject it in validation with a friendly "zstd requires Python 3.14+" message. If
+it were dropped from `choices` on older runtimes, argparse would emit a generic
+"invalid choice" that reads as though the option never existed — worse UX.
+
+### Import-side compatibility
+
+`document_importer` reads zips with `ZipFile(self.source).extractall(...)`
+(`document_importer.py:453`), which decompresses each entry transparently using
+whatever method it was stored with — **provided the matching module exists on the
+importing machine.**
+
+The failure mode when it doesn't is unfriendly and must be handled: a zstd (or
+otherwise unsupported) entry raises a bare `NotImplementedError` **per-entry,
+during `extractall`** — _not_ at `ZipFile(self.source)` open, and `is_zipfile()`
+still returns true (a zstd archive is a valid zip container). So the importer
+enters the zip branch, creates its temp dir, may partially extract other entries,
+then blows up mid-extract with no context. **Mitigation (in scope here):** before
+extracting, inspect `ZipFile(self.source).infolist()` compress types and, if any
+is unsupported on this runtime, raise a `CommandError` naming the method and the
+requirement (e.g. "this archive uses zstd, which needs Python 3.14+") instead of
+letting `NotImplementedError` escape.
+
+Per-method summary (document in help text + `administration.md`):
+
+- `deflated`/`stored`: universally importable.
+- `bzip2`/`lzma`: importable wherever the `bz2`/`lzma` modules are present
+  (essentially always).
+- `zstd`: importable only on Python 3.14+. An archive compressed with `zstd` is
+  **not** importable on older runtimes.
+
+## Testing
+
+New cases in the sink tests and an export→import round-trip
+(pytest classes, factory-boy, `mocker`, `parametrize`, typed; run on the VM):
+
+- **Round-trip per method.** Parametrize over the available methods (skip `zstd`
+  below 3.14, skip `bzip2`/`lzma` if the module is somehow absent): export a
+  small library, import it back, assert documents/manifest match.
+- **Method is applied.** Assert each written _file_ entry's `compress_type`
+  equals the requested method (read back via `ZipFile.infolist()`), filtering out
+  directory marker entries (which are tagged but empty).
+- **Level affects size — robustly.** Do **not** compare deflate level 9 vs 1
+  (on small or incompressible fixtures level 9 can equal or slightly exceed level
+  1, causing flaky CI). Instead assert that a compressing method on a
+  moderately-compressible fixture yields a total smaller than `stored`
+  (`ZIP_STORED`), which is a stable invariant.
+- **Validation.** Each flag without `--zip` → `CommandError`; out-of-range level
+  (`--zip-compression-level 99`) → a clean `CommandError` from validation
+  (asserting we never reach the `writestr` that would raise the masked
+  `ValueError`); `--zip-compression-level` with `stored`/`lzma` → `CommandError`;
+  unavailable method (patch the named availability seam with `mocker`) →
+  `CommandError`; on < 3.14, `--zip-compression zstd` → the friendly
+  "requires 3.14+" `CommandError`.
+- **Import pre-check.** An archive containing an unsupported compress type
+  produces a `CommandError` from the importer naming the method, not a raw
+  `NotImplementedError` (simulate by patching the importer's support probe).
+- **Default unchanged.** Omitting both flags yields file entries with
+  `compress_type == ZIP_DEFLATED`, identical to pre-feature behavior.
+
+## Risks
+
+- **Foot-gun archives.** A user could produce a `zstd`/`lzma` archive their
+  import target can't read. Mitigation: explicit help text and the import-side
+  notes above; the default stays the universally-readable `deflated`.
+- **Optional-module assumptions.** Don't assume `bz2`/`lzma` are always compiled
+  in; probe and error clearly. Mitigation: the availability validation step.

+# Ingestion Staging & Enqueue Unification — Design
+
+**Date:** 2026-06-16
+**Branch base:** `dev`
+**Status:** Approved design (revised per critical review), pending implementation plan
+
+## Problem
+
+Every document that enters paperless converges on one operation: build a
+`ConsumableDocument` + `DocumentMetadataOverrides`, stage the input file on disk,
+and dispatch the `consume_file` Celery task with a `trigger_source` header. That
+operation is hand-rolled at **five** sites today, plus a sixth internal one:
+
+- consume-folder watcher — `document_consumer.py:342`
+- API upload + Web UI — `views.py:3181` (one endpoint, two `DocumentSource` values)
+- document-version upload — `views.py:1964`
+- mail attachment — `mail.py:899`
+- mail `.eml` whole-message — `mail.py:987`
+- barcode split children (internal re-enqueue) — `barcodes.py:190`/`227`
+
+The duplication causes three concrete problems:
+
+1. **Boilerplate divergence.** Each site repeats `SCRATCH_DIR.mkdir`, a per-file
+   `tempfile.mkdtemp`, the payload write, the `magic` MIME sniff, the
+   `consume_file` kwargs shape, and the `DocumentSource → PaperlessTask.TriggerSource`
+   mapping. That mapping is even re-implemented a second time as
+   `_SOURCE_TO_TRIGGER` inside `barcodes.py:198`.
+
+2. **A scratch leak from split staging/cleanup ownership.** Staged sources create
+   scratch input under `SCRATCH_DIR` that nothing ever fully removes:
+   `ConsumerPlugin` unlinks only the input **file**, and only on the success path
+   (`consumer.py:742`). The exact leak shape varies by site — mail attachments and
+   API/version use `mkdtemp` + a file inside, so the **directory** is orphaned
+   (empty after success, dir-with-file on failure); the mail `.eml` path uses
+   `mkstemp` (`mail.py:~955`), so it leaks a **file** directly in `SCRATCH_DIR` on
+   failure. Either way there is no owner that removes the staged input on every
+   terminal path.
+
+3. **Three test seams for one operation.** `ConsumeTaskMixin` patches
+   `documents.tasks.consume_file.apply_async` (`tests/utils.py:249`); the
+   consumer-folder tests patch the module-local `consume_file`
+   (`test_management_consumer.py:101`); mail patches the higher-level
+   `queue_consumption_tasks`. There is no single canonical point to intercept
+   "a document was enqueued."
+
+Separately, the consumption task already has **two** working temp directories that
+duplicate each other: `consume_file` opens one `TemporaryDirectory` and passes it
+to every plugin (`tasks.py:220`), but `ConsumerPlugin` ignores that and opens its
+_own_ second `TemporaryDirectory` (`consumer.py:417`).
+
+## Goal
+
+Introduce one small ingestion module that owns staging and enqueue, so each site
+declares only its genuinely source-specific logic (how the overrides dict is
+built). Give every ingested document a single per-document working directory that
+holds the staged input _and_ all pipeline working artifacts, cleaned up as a unit
+on every terminal path. Collapse the three test seams to one.
+
+## Scope
+
+In scope:
+
+- New `src/documents/ingest.py`: the canonical `SOURCE_TO_TRIGGER` map,
+  `build_consume_signature`, `enqueue_consumption`, and `stage_document`.
+- `ConsumableDocument` gains `staging_dir: Path | None`.
+- `consume_file` derives a per-document `work_root` from `staging_dir` and removes
+  it on every terminal path; `ConsumerPlugin` reuses the handed-in working dir
+  instead of opening a second one.
+- Refactor all six enqueue sites (including the barcode split children) onto the
+  new module.
+- Update the shared test seam (`ConsumeTaskMixin`) and the consumer-folder tests;
+  add unit tests for `ingest.py`.
+
+Out of scope (explicitly — confirmed during exploration):
+
+- **`bulk_edit.py`'s 8 dispatch sites (phase 2).** Bulk merge/split/version
+  (`bulk_edit.py:485,588,661,727,811,844,938,961`) also build `ConsumableDocument`s
+  and dispatch `consume_file`. They are deferred to a follow-up plan that adopts
+  the seam this refactor establishes. Consequence: until phase 2, the "single
+  canonical seam" is partial — those paths still call `consume_file` directly. The
+  spec states this rather than implying full unification.
+- **New poller sources (S3/SFTP/webhook).** They need infrastructure that does not
+  exist (a scheduling/registration framework, per-source credential/config models,
+  a generic already-seen dedup table, new `DocumentSource`/`TriggerSource` enum
+  values). This refactor unifies the _last mile_ (staging + enqueue); it does not
+  build poller infrastructure and should not be sold as doing so.
+- **Finishing Gmail/Outlook OAuth.** Both already work via IMAP+XOAUTH2; the
+  remaining items (`oauth.py:94` missing `else` guard, the callback
+  `update_or_create` lookup-key bug, unpopulated username, no Graph API path) are
+  independent bug fixes that neither need nor are needed by this refactor.
+- **The `DocumentSource.WebUI` vs `ApiUpload` split** (a request-body boolean on
+  one endpoint) — left as-is.
+- Any entry-point / third-party plugin extensibility for sources.
+
+## Decisions
+
+Settled during brainstorming:
+
+1. **Shape: a staging object + an enqueue seam, not per-source adapter classes.**
+   Source-specific override-building stays inline at each site; only staging and
+   dispatch are extracted. A `SourceAdapter` class hierarchy is premature (the
+   pollers that would justify it are out of scope).
+2. **Cleanup: an explicit lifecycle carried on `ConsumableDocument`.** A
+   `staging_dir` field transfers ownership of the staged file from the enqueue
+   site to the worker. No periodic sweep (the only residual leak window —
+   broker accepts the task then loses it before execution — is negligibly small).
+3. **Grouping: one per-document root holds everything.** The staged input and the
+   task's working artifacts live under a single directory, removed by one
+   `rmtree`. This also folds away `ConsumerPlugin`'s redundant second temp dir.
+4. **One canonical dispatch seam: `enqueue_consumption`.** Tests patch it in one
+   place — **but only because** of two implementation constraints the plan must
+   enforce: (a) sites call it **module-qualified** (`ingest.enqueue_consumption(...)`,
+   not a bare imported name), so a single `documents.ingest.enqueue_consumption`
+   patch intercepts every site; (b) `build_consume_signature` passes
+   `input_doc`/`overrides` as **keyword** args, so `Signature.kwargs` keeps the
+   shape mail tests already assert on. Without both, the "one patch point" claim is
+   false.
+
+## Architecture
+
+### New module `src/documents/ingest.py`
+
+```python
+SOURCE_TO_TRIGGER: dict[DocumentSource, PaperlessTask.TriggerSource] = { ... }
+# the single source of truth; barcodes.py imports this instead of redefining it.
+
+def build_consume_signature(
+    input_doc: ConsumableDocument,
+    overrides: DocumentMetadataOverrides | None = None,
+) -> Signature:
+    """Build the consume_file signature with the trigger_source header derived
+    from input_doc.source. Returns a Celery Signature — the caller decides how to
+    dispatch (direct .apply_async(), or collected into mail's chord)."""
+
+def enqueue_consumption(
+    input_doc: ConsumableDocument,
+    overrides: DocumentMetadataOverrides | None = None,
+) -> AsyncResult:
+    """Canonical dispatch seam: build_consume_signature(...).apply_async().
+    The single point tests patch to intercept 'a document was enqueued'."""
+
+class StagedDocument:
+    """Commit-on-success guard for a staged input file.
+
+    Created via stage_document(). Owns a per-document work_root under SCRATCH_DIR
+    until the caller calls release() (after successful dispatch), at which point
+    ownership transfers to the consume_file task via input_doc.staging_dir.
+    """
+    input_doc: ConsumableDocument          # carries staging_dir = work_root
+    def write(self, data: bytes) -> None: ...        # write payload into work_root
+    def write_from(self, src: Path) -> None: ...     # copy an existing file in
+    def release(self) -> None: ...                   # dispatch succeeded; don't clean
+    # __enter__ -> self;  __exit__ -> if not released, rmtree(work_root)
+
+@contextmanager
+def stage_document(source: DocumentSource, *, name: str) -> Iterator[StagedDocument]:
+    """mkdtemp a per-document work_root under SCRATCH_DIR, yield a StagedDocument
+    to write into. MIME type is sniffed when the ConsumableDocument is built."""
+```
+
+### `ConsumableDocument.staging_dir` (`data_models.py`)
+
+Add `staging_dir: Path | None = None`. It is the field that crosses the
+enqueue→worker boundary (picklable; the HMAC-pickle Celery serializer is
+unaffected). Folder source leaves it `None`; all staged sources set it to their
+`work_root`.
+
+### Ownership-transfer model
+
+The staged file must outlive the synchronous enqueue and be consumed later by the
+worker, so a context manager around the enqueue site cannot delete it. Ownership
+transfers at the **successful-dispatch boundary**:
+
+- **Enqueue side (`StagedDocument`):** owns `work_root` only until `release()`. If
+  an exception occurs before/at dispatch (building overrides, writing the file,
+  `apply_async` raising), `__exit__` runs without a prior `release()` and
+  `rmtree`s `work_root` — closing the failure-path leak. After `release()`,
+  `__exit__` is a no-op and the directory deliberately survives.
+- **Worker side (`consume_file`):** once the task runs, the task owns `work_root`
+  (via `input_doc.staging_dir`) and removes it in a `finally` on **every**
+  terminal path.
+
+### `consume_file` work_root + cleanup (`tasks.py`)
+
+Replace the unconditional `TemporaryDirectory(dir=SCRATCH_DIR)` (`tasks.py:220`)
+with a derived work_root:
+
+- `input_doc.staging_dir` set → `work_root = staging_dir` (already holds the
+  input). The task owns it and `rmtree`s it in a `finally` covering success,
+  `StopConsumeTaskError`, `ConsumeFileDuplicateError`, and unexpected exceptions.
+- `staging_dir is None` (folder) → `work_root` is a fresh `TemporaryDirectory`
+  (auto-cleaned); the in-place original in `CONSUMPTION_DIR` is unlinked by
+  `ConsumerPlugin` on success exactly as today.
+
+The per-task working directory passed to plugins becomes a **subfolder of
+work_root**, and `ConsumerPlugin` uses that handed-in directory for its working
+copy instead of opening its own second `TemporaryDirectory` (`consumer.py:417`).
+One tree per document; one cleanup.
+
+### Barcode split children (`barcodes.py`)
+
+The split re-enqueue produces each child via `stage_document` +
+`build_consume_signature` using `SOURCE_TO_TRIGGER`, removing the sixth
+hand-rolled site and the `_SOURCE_TO_TRIGGER` duplicate. **This is a
+restructuring, not a swap:** today all children share a single `mkdtemp` dir
+(`barcodes.py:188-194`, deliberately separate from the parent's `base_temp_dir`).
+Each child must instead get its **own** work_root, because each child is a
+separate `consume_file` task whose `finally` will `rmtree` its `staging_dir` — a
+shared dir would let one child delete siblings' not-yet-consumed files. The
+children already copy their split file out of the parent tree
+(`copy_file_with_basic_stats`, `barcodes.py:211`), so the parent's work_root is
+independently cleanable when the parent stops.
+
+### Mail ownership boundary (the batch case — `mail.py`)
+
+Mail is the one source that does **not** dispatch per file: `_handle_message`
+collects N attachment signatures (and optionally the `.eml` signature), then
+`queue_consumption_tasks` wraps them in a single `chord(...).delay()` _after_ the
+loop (`mail.py:919`). A per-file `release()` is therefore wrong — if `release()`
+ran per attachment and the later chord dispatch threw, every staged file would be
+orphaned, reopening the leak. **The ownership boundary is the whole message:**
+
+```python
+def _handle_message(...):
+    with contextlib.ExitStack() as staging_stack:
+        consume_tasks = []
+        for att in attachments:               # and the .eml branch
+            staged = staging_stack.enter_context(stage_document(MailFetch, name=...))
+            staged.write(att.payload)
+            consume_tasks.append(build_consume_signature(staged.input_doc, overrides))
+        queue_consumption_tasks(consume_tasks, rule, message)   # chord(...).delay()
+        for staged in staged_docs:
+            staged.release()                  # only after the chord is dispatched
+    # ExitStack __exit__: any un-released staged doc → rmtree (covers a chord-dispatch failure)
+```
+
+`queue_consumption_tasks` itself is unchanged. `build_consume_signature` **must
+pass `input_doc`/`overrides` as keyword args** (`consume_file.s(input_doc=...,
+overrides=...)`) so the resulting `Signature.kwargs` keeps the shape mail tests
+assert on (`test_mail.py:365-366`).
+
+### Call-site refactor (the external sites)
+
+Folder/API/version collapse to: `with stage_document(...) as staged:
+staged.write(...); overrides = DocumentMetadataOverrides(...source-specific...);
+ingest.enqueue_consumption(staged.input_doc, overrides); staged.release()`. Folder
+source has no payload to stage (the file is already in `CONSUMPTION_DIR`), so it
+builds a `ConsumableDocument(..., staging_dir=None)` and calls
+`ingest.enqueue_consumption` directly without `stage_document`. Mail uses the
+`ExitStack` pattern above.
+
+**Call style is module-qualified.** Sites do `from documents import ingest` and
+call `ingest.enqueue_consumption(...)` / `ingest.build_consume_signature(...)` —
+_not_ a bare imported name. This is what makes a single patch target
+(`documents.ingest.enqueue_consumption`) intercept every site; a direct
+`from documents.ingest import enqueue_consumption` would bind the name per-module
+and force per-module patching (the existing `from documents.tasks import
+consume_file` style is exactly why tests today need multiple patch targets).
+
+## Data flow
+
+```
+folder / API / version site (synchronous, single dispatch)
+  with stage_document(source, name=...) as staged:     # mkdtemp work_root, write input
+      overrides = DocumentMetadataOverrides(... per-source ...)
+      result = ingest.enqueue_consumption(staged.input_doc, overrides)
+      staged.release()                                  # ownership → task
+  # __exit__: rmtree(work_root) ONLY if release() never ran (pre-dispatch failure)
+  # (folder source: no stage_document; ConsumableDocument(staging_dir=None) + enqueue_consumption)
+
+mail site (synchronous, BATCH dispatch — see "Mail ownership boundary")
+  with ExitStack() as staging_stack:                   # owns ALL of the message's staged docs
+      build N signatures via ingest.build_consume_signature(... keyword args ...)
+      queue_consumption_tasks(...)                      # one chord(...).delay()
+      release() every staged doc                        # only after the chord dispatches
+  # __exit__: rmtree any un-released work_root (a chord-dispatch failure cleans the whole batch)
+
+consume_file task (async, later)
+  work_root = input_doc.staging_dir or TemporaryDirectory(SCRATCH_DIR)
+  try:
+      run plugin chain (working files under work_root/work, input at work_root/...)
+  finally:
+      if input_doc.staging_dir: rmtree(work_root)       # all terminal paths
+      # folder source: TemporaryDirectory auto-cleans; ConsumerPlugin unlinks original
+```
+
+## Error handling & edges
+
+- **Double-sided collation — safe, but outside the work_root model.** It stops
+  with `StopConsumeTaskError` to await the second half, and preserves that half by
+  **`shutil.move(pdf_file, staging)`** to `SCRATCH_DIR/<staging-name>`
+  (`double_sided.py:~134`) — a _move_, to a location _outside_ any work_root,
+  performed **before** the stop. So `rmtree`-ing the parent work_root afterward is
+  safe (the half already left the tree). Two consequences the plan must honor:
+  (a) the preserved staging file lives in `SCRATCH_DIR`, is **never** covered by
+  the per-document cleanup, and is cleaned by the second-half collate
+  (`staging.unlink()`) or timeout as today — the "one root" framing does not
+  extend to it; (b) the plan must verify the move-precedes-stop ordering, since it
+  is load-bearing for the cleanup rule.
+- **`ConsumerPlugin`'s own cleanup becomes partly redundant.** On success it
+  unlinks `original_file` and `working_copy` (`consumer.py:742/744`), both of
+  which now live inside work_root that the task `finally` `rmtree`s. The redundant
+  unlinks are harmless but the plan should remove them for clarity, while keeping
+  the qpdf `--replace-input` recovery (`unmodified_original`, `consumer.py:452+`)
+  working when `working_copy` lives under work_root.
+- **Folder source is intrinsically asymmetric** — its original lives in the
+  watched dir, not a work_root. The "one root" model fully applies to staged
+  sources; folder gets in-place-original (cleaned by `ConsumerPlugin` on success)
+  plus an isolated per-task working root. This is correct, not a gap.
+- **`staging_dir is None` must be a strict no-op.** Many integration tests call
+  the real `consume_file` with hand-built `ConsumableDocument`s that never set
+  `staging_dir` (`test_workflows.py`, `test_barcodes.py`, `test_double_sided.py`).
+  The new work_root/`finally` logic must reduce to exactly today's behavior when
+  `staging_dir is None`, or those currently-passing tests regress.
+- **Duplicate/stop are not failures.** The worker `finally` cleans `work_root` on
+  every terminal path, but a future quarantine feature (below) would relocate the
+  input only on a genuine exception, never on `ConsumeFileDuplicateError` or
+  `StopConsumeTaskError`.
+
+## Testing
+
+New `src/documents/tests/` unit tests for `ingest.py` (pytest-style classes,
+`mocker`, type-annotated):
+
+- `stage_document` cleans `work_root` on an exception before `release()`, and does
+  **not** clean it after `release()` (ownership transferred) — i.e. the leak is
+  closed and the file survives for the task.
+- `build_consume_signature` sets the correct `trigger_source` header for each
+  `DocumentSource` (drives `SOURCE_TO_TRIGGER`).
+- `enqueue_consumption` dispatches and returns the `AsyncResult`.
+- `consume_file` removes `staging_dir` on success, on `StopConsumeTaskError`, on
+  duplicate, and on exception; and does nothing destructive when `staging_dir`
+  is `None` (folder source) beyond today's behavior.
+- The `trigger_source` header survives `Signature.set(headers=...).apply_async()`
+  **and** chord dispatch (a guard against chord wrapping dropping per-signature
+  headers — the one path where header propagation could silently break).
+
+Existing tests — the migration is centralized but **not** trivial:
+
+- `ConsumeTaskMixin` (`tests/utils.py:242-280`): repoint the patch from
+  `documents.tasks.consume_file.apply_async` to `documents.ingest.enqueue_consumption`,
+  **and rewrite both assert helpers** — they currently read the raw `apply_async`
+  shape `call_args.kwargs["kwargs"]["input_doc"]` (`assert_queue_consumption_task_call_args`
+  at :259 and `get_all_consume_task_call_args` at :267). With the seam called
+  positionally as `enqueue_consumption(input_doc, overrides)`, those become
+  `call_args.args[0]/[1]`. This is concentrated in the mixin, so its ~15 helper
+  call sites in `test_api_documents.py` + 1 in `test_barcodes.py` pass once the
+  helpers are fixed — but it is a helper rewrite, not a one-line change.
+- The consumer-folder tests (`test_management_consumer.py`, ~15 methods) repoint
+  `mock_consume_file_delay` to the seam.
+- `test_api_document_versions.py` (3 tests) patches the **module-local**
+  `documents.views.consume_file` — repoint to `documents.views`-qualified usage or
+  the central seam.
+- Real-task integration tests that build `ConsumableDocument`s by hand and call
+  `consume_file` directly (`test_workflows.py` ~15, `test_barcodes.py` ~5,
+  `test_double_sided.py` ~9) exercise the `staging_dir is None` path; they should
+  stay green **iff** that path is a strict no-op (see Error handling).
+- Mail tests that patch `queue_consumption_tasks` stay untouched **only if**
+  `build_consume_signature` uses keyword args (above); otherwise their assertions
+  on `Signature.kwargs` (`test_mail.py`, `test_mail_nfc.py`, `test_preprocessor.py`,
+  ~15 methods) break.
+
+**Realistic blast radius: ~70–90 in-scope test methods** route through the
+changed seams (the export-style "one patch point" still holds, but the helper
+rewrite + keyword-arg + module-qualified constraints are what make it true). This
+excludes `bulk_edit.py`'s ~35 tests, which are deferred with their migration to
+the bulk-edit phase-2 plan.
+
+## Enabled future work (not built here)
+
+**Quarantine failed files for review.** Because failure cleanup collapses to the
+single `finally` in `consume_file` that owns `work_root`, a "save failed
+documents to a review folder" feature becomes a one-site change: on a genuine
+exception (not duplicate/stop), move the staged input to a configured
+`PAPERLESS_FAILED_DIR` instead of `rmtree`-ing it, then drop the working
+subfolder. `staging_dir` already names the file and marks it relocatable, and the
+terminal result type is already known at that point, so the feature applies
+uniformly to every staged source from one edit. It would also unify a current
+inconsistency (failed folder files loop in `CONSUMPTION_DIR`; failed mail/API
+files are lost). Note: this refactor changes mail/API failure behavior from
+"silently leak the temp file" to "cleanly delete it," so until a review folder
+lands, a failed mail/API input is gone — mild pressure to build quarantine sooner
+if it is wanted.
+
+## Risks
+
+- **Cleanup must run on all terminal paths.** The worker `finally` must cover
+  success, `StopConsumeTaskError`, `ConsumeFileDuplicateError`, and unexpected
+  exceptions, or the leak reappears. Covered by the `consume_file` tests above.
+- **Test-seam migration churn.** ~70–90 in-scope test methods route through the
+  changed seams. Mitigation: concentrated in `ConsumeTaskMixin` (helper rewrite)
+  and a few fixtures — but it is a helper rewrite plus a keyword-arg and a
+  module-qualified-call contract, not a one-line repoint. The plan must encode all
+  three constraints or the "single patch point" promise is false.
+- **Mail batch ownership.** The `ExitStack` boundary (release all only after the
+  chord dispatches; rmtree-all on dispatch failure) is load-bearing; getting it
+  per-attachment instead reopens the leak for the whole message.
+- **Double-sided ordering.** The move-precedes-stop assumption
+  (`shutil.move` to `SCRATCH_DIR` at `double_sided.py:~134`) must be verified in
+  the plan before relying on it for cleanup.
+- **`bulk_edit.py` is deferred, not done.** Until the phase-2 plan migrates its 8
+  dispatch sites, the "single canonical seam" is partial: bulk merge/split/version
+  still call `consume_file` directly. The spec states this honestly rather than
+  implying full unification.

+# Usage Reporting — Technical Spec
+
+Voluntary, opt-in usage reporting for paperless-ngx. The goal is to
+understand how many instances are running a given release (especially
+beta), which platforms and architectures are in use, and what features
+are being deployed — without collecting any personal data or document
+content.
+
+---
+
+## Guiding principles
+
+- **Explicitly opt-in.** Nothing is sent automatically. The user runs
+  the command and confirms before any network call is made.
+- **Transparent.** The exact payload is shown before sending.
+- **Anonymous.** The UUID is a random identifier with no link to
+  identity, IP address, or hostname.
+- **Graceful.** Network failures produce a friendly message, never a
+  stack trace.
+
+---
+
+## Client — management command
+
+### Name
+
+```
+manage.py send_usage_report
+```
+
+### Flags
+
+| Flag        | Behaviour                                                 |
+| ----------- | --------------------------------------------------------- |
+| _(none)_    | Show payload, prompt for confirmation, send on `y`/`yes`  |
+| `--dry-run` | Show payload, skip confirmation and network call entirely |
+
+### UUID storage
+
+A random UUID4 is generated on the first run and written to
+`PAPERLESS_DATA_DIR/usage_uuid` (plain text, one line). Subsequent
+runs reuse the same file. If the file is missing it is regenerated
+(counts as a new install — acceptable).
+
+### Confirmation flow
+
+```
+The following information will be sent to paperless-ngx to help
+improve the project:
+
+  Installation ID : a1b2c3d4-e5f6-7890-abcd-ef1234567890
+  Version         : 2.15.0
+  Channel         : beta
+  Commit          : bd86dca57  (built 2026-05-18T12:00:00Z)
+  Install type    : docker
+  Architecture    : x86_64
+  Python          : 3.12.3
+  Database        : postgresql
+  Documents       : 1000–9999
+  Multi-user      : yes
+  Mail enabled    : yes
+  AI enabled      : no
+
+No personal data, document content, or IP address is stored.
+More information: https://docs.paperless-ngx.com/usage-reporting/
+
+Send this report? [y/N]:
+```
+
+Default answer is **N**. Anything other than `y`/`yes` aborts with
+no network call and prints `Nothing sent.`
+
+`--dry-run` skips the prompt entirely and prints `Dry run — nothing sent.`
+
+### Network error handling
+
+- Timeout: 10 seconds
+- On any failure (timeout, DNS, HTTP error): print a single friendly
+  line, exit 0 (not an error from the user's perspective)
+
+```
+Could not reach the reporting endpoint. Nothing was sent.
+```
+
+### Duplicate submission handling
+
+The server returns `429` if the UUID was seen within the last 7 days,
+with a JSON body:
+
+```json
+{
+  "error": "already_submitted",
+  "last_sent": "2026-05-15T10:00:00Z",
+  "retry_after_days": 4
+}
+```
+
+The command prints:
+
+```
+Already submitted 3 days ago. Nothing sent.
+You can send again after 2026-05-19.
+```

+
+Distro packagers (Debian, NixOS community, Unraid, etc.) can opt in
+by shipping a `src/paperless/distro_info.py` containing:
+
+```python
+DISTRO = "debian"   # or "rpm", "homebrew", "unraid", etc.
+```
+
+When present the install type is reported as the `DISTRO` value rather
+than `"distro"`.
+
+### `version.py` additions
+
+Add `__channel__` alongside the existing version fields:
+
+```python
+__channel__: Final[str] = "beta"   # "stable" | "beta" | "dev"
+```
+
+This is the canonical place to set the channel when preparing a
+release. `"dev"` is the default for unreleased branches.
+
+### `build_info.py`
+
+Generated at build time, never committed (add to `.gitignore`).
+
+```python
+SOURCE_COMMIT = "bd86dca57"
+BUILD_DATE = "2026-05-18T12:00:00Z"
+```

+## Server — Cloudflare Worker
+
+Managed in a separate repository under the paperless-ngx GitHub org
+(e.g. `paperless-ngx/telemetry`). Deployed via Wrangler.
+
+### Endpoint
+
+```
+POST /report
+Content-Type: application/json
+```
+
+Returns `204` on success. No response body.
+
+### Timestamp
+
+`received` is always set server-side. Any client-supplied timestamp
+field is ignored.
+
+### Validation
+
+Reject with `400` if any of the following fail:
+
+- `uuid` does not match UUID4 format
+- `version` does not match `\d+\.\d+\.\d+`
+- `channel` is not one of `stable`, `beta`, `dev`
+- `install_type` is not in the known set
+- `arch` is absent
+- Payload is not valid JSON or exceeds 4 KB
+
+Unknown extra fields are silently ignored (forward compatibility).
+
+### Deduplication
+
+Before inserting, query for the most recent submission from this UUID:
+
+```sql
+SELECT received FROM reports
+WHERE uuid = ?
+ORDER BY received DESC
+LIMIT 1
+```
+
+If the result is within 7 days of now, return:
+
+```
+HTTP 429
+{ "error": "already_submitted", "last_sent": "<iso>", "retry_after_days": <n> }
+```
+
+Otherwise insert and return `204`.
+
+### D1 schema
+
+```sql
+CREATE TABLE reports (
+  id            INTEGER PRIMARY KEY,
+  received      TEXT    NOT NULL,   -- ISO 8601, server-side
