+## Minimum CPU Requirements (NumPy Baseline)
+
+Starting with NumPy 2.4.0, official `manylinux` x86_64 wheels are compiled with a minimum
+CPU baseline of `x86-64-v2`, which requires SSE3, SSSE3, SSE4.1, SSE4.2, POPCNT, and
+CMPXCHG16B. This is a [deliberate upstream change](https://github.com/numpy/numpy/issues/27851)
+citing that these instructions have been present in over 99.7% of CPUs since 2008
+([Intel](<https://en.wikipedia.org/wiki/Nehalem_(microarchitecture)>)) or 2011
+([AMD](<https://en.wikipedia.org/wiki/Bulldozer_(microarchitecture)>)).
+
+NumPy is a dependency of the document classifier (via scikit-learn), so any CPU that
+predates SSE4.2 support will crash with `SIGILL` (illegal instruction) when the classifier
+is loaded or trained, regardless of whether AI features are enabled.
+
+This differs from NumPy's optional SIMD dispatch (e.g. AVX2, AVX512), which is detected and
+selected safely at runtime - the `x86-64-v2` requirement above is a hard floor baked into the
+wheel, with no runtime fallback.
+
+### Affected hardware
+
+CPUs older than roughly 2008 (Intel) or 2011 (AMD) that lack SSE4.2 support. This is more
+likely to affect low-power or embedded hardware - e.g. early Atom, Celeron, or pre-Bulldozer
+AMD chips - than typical desktop or server hardware from the last decade.
+
+Check for SSE4.2 support with:
+
+```bash
+grep -o -m1 sse4_2 /proc/cpuinfo
+```
+
+If this prints nothing, your CPU is affected.
+
+### Symptoms
+
+The Celery worker (and potentially the web server) repeatedly crashes and restarts with a
+`SIGILL` error, typically visible in `dmesg`/`journalctl` as a `trap invalid opcode` inside
+`_multiarray_umath...so`. Because the classifier is trained on a periodic schedule
+(hourly, by default), affected instances see intermittent, hard-to-reproduce document
+consumption failures whenever that scheduled task runs and takes down the worker process
+mid-task.
+
+### Action Required (for affected hardware only)
+
+There is no way to make the classifier itself work on such CPUs - it requires an unofficial
+NumPy build with `cpu-baseline=none`, which is not something we can ship. The practical
+path forward is to stop the classifier from ever loading or training, which avoids
+importing NumPy at all:
+
+```bash
+PAPERLESS_TRAIN_TASK_CRON=disable
+```
+
+This disables the periodic classifier training task (see
+[`PAPERLESS_TRAIN_TASK_CRON`](configuration.md#PAPERLESS_TRAIN_TASK_CRON)). Automatic
+matching based on the classifier (suggested correspondents, document types, tags, and
+storage paths from trained rules) will no longer be available, but rule-based matching is
+unaffected, and document consumption itself will no longer be at risk of crashing the
+worker.

+# 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.

+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

+```bash
+bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_vector_store.py::TestMigrationRegistry -v"
+```
+
+Expected: all 7 tests fail — `Migration`, `MIGRATIONS`, `pending_migrations`, `requires_reembed_migration` don't exist yet.
+
+- [ ] **Step 3: Add `Migration` dataclass and registry to `vector_store.py`**
+
+Add near the top of the file, after the existing imports:
+
+```python
+from dataclasses import dataclass, field
+from typing import Callable
+```
+
+After the `CURRENT_SCHEMA_VERSION` constant, add:
+
+```python
+@dataclass(frozen=True)
+class Migration:
+    version: int
+    description: str
+    requires_reembed: bool
+    apply: Callable[[Any], None] = field(compare=False, hash=False)
+```
+
+(`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
+
+# add_columns/alter_columns/drop_columns APIs — no re-embedding needed.
+
+# Migrations with requires_reembed=True cause a full rebuild on next index update,
+
+# exactly like a model-name change does today.
+
+#
+
+# To add a migration:
+
+# 1. Increment CURRENT_SCHEMA_VERSION.
+
+# 2. Append a Migration entry here with the new version number.
+
+# 3. For structural changes, call table.add_columns/alter_columns/drop_columns in apply().
+
+# 4. For embedding-invalidating changes, set requires_reembed=True; apply() can be a no-op.
+
+MIGRATIONS: list[Migration] = []
+
+````
+
+Inside `PaperlessLanceVectorStore`, add after `requires_reembed_migration` (which we'll add next):
+
+```python
+def pending_migrations(self) -> list[Migration]:
+    """Return migrations not yet applied to this table, in version order."""
+    if self._table is None:

+
+## 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**
+
+  ```
+  bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_embedding.py::test_build_llm_index_text -v"
+  ```
+
+  Expected: `FAILED` — `AssertionError: assert 'Filename: test_file.pdf' not in '...'`
+
+---
+
+### Task 2: Pass — remove the three fields from `build_llm_index_text`
+
+**Files:**
+
+- Modify: `src/paperless_ai/embedding.py`
+
+- [ ] **Step 1: Remove the three lines and the TODO comment**
+
+  Current `build_llm_index_text` (lines 114–133). Replace the function body:
+
+  ```python
+  def build_llm_index_text(doc: Document) -> str:
+      lines = [
+          f"Notes: {','.join([str(c.note) for c in Note.objects.filter(document=doc)])}",
+      ]
+
+      for instance in doc.custom_fields.all():
+          lines.append(f"Custom Field - {instance.field.name}: {instance}")
+
+      lines.append("\nContent:\n")
+      lines.append(doc.content or "")
+
+      return _normalize_llm_index_text("\n".join(lines))
+  ```
+
+- [ ] **Step 2: Run the test to confirm it passes**
+
+  ```
+  bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_embedding.py::test_build_llm_index_text -v"
+  ```
+
+  Expected: `PASSED`
+
+- [ ] **Step 3: Run the full embedding test module to catch regressions**
+
+  ```
+  bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_embedding.py -v"
+  ```
+
+  Expected: all green.
+
+- [ ] **Step 4: Commit**
+
+  ```bash
+  git add src/paperless_ai/embedding.py src/paperless_ai/tests/test_embedding.py
+  git commit -m "refactor(ai): remove filename/storage_path/asn from embedding text"
+  ```
+

+
+### Task 3: Fail — `build_document_node` exposes the three fields in metadata
+
+**Files:**
+
+- 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 len(nodes) > 0
+      for node in nodes:
+          assert "title" in node.metadata
+          assert "tags" in node.metadata
+          assert "correspondent" in node.metadata
+          assert "document_type" in node.metadata
+          assert "created" in node.metadata
+          assert "added" in node.metadata
+          assert "modified" in node.metadata
+          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)
+          assert "filename" not in embed_text
+          assert "storage_path" not in embed_text
+          assert "archive_serial_number" not in embed_text
+  ```
+
+- [ ] **Step 4: Run the new tests to confirm they fail**
+
+  ```
+  bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_ai_indexing.py::test_build_document_node_structured_fields_in_metadata src/paperless_ai/tests/test_ai_indexing.py::test_build_document_node_storage_path_name_in_metadata src/paperless_ai/tests/test_ai_indexing.py::test_build_document_node_new_fields_excluded_from_embedding -v"
+  ```
+
+  Expected: all `FAILED` — keys not yet in `node.metadata`.
+

+
+### 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,
+      "archive_serial_number": document.archive_serial_number,

+      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(),
+  }
+  ```
+
+- [ ] **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.
+
+- [ ] **Step 3: Run the failing tests to confirm they pass**
+
+  ```
+  bash /c/Users/tholmes/Documents/Coding/paperless/vmtest.sh "src/paperless_ai/tests/test_ai_indexing.py::test_build_document_node_structured_fields_in_metadata src/paperless_ai/tests/test_ai_indexing.py::test_build_document_node_storage_path_name_in_metadata src/paperless_ai/tests/test_ai_indexing.py::test_build_document_node_new_fields_excluded_from_embedding -v"

+
+  Expected: all green.
+
+- [ ] **Step 5: Commit**
+
+  ```bash
+  git add src/paperless_ai/indexing.py src/paperless_ai/tests/test_ai_indexing.py
+  git commit -m "feat(ai): add filename/storage_path/asn to node metadata"

+
+### Task 5: Fail — migration v2 is registered
+
+**Files:**
+
+- Modify: `src/paperless_ai/tests/test_vector_store.py`
+
+These tests use the real (non-mocked) `MIGRATIONS` list, so they go red until the migration is registered in Task 6.
+
+- [ ] **Step 1: Add a `TestMetadataEnrichmentMigration` class**
+
+  Add this class near the end of `test_vector_store.py`, before the final `TestApplyStructuralMigrations`:
+
+  ```python
+  class TestMetadataEnrichmentMigration:
+      def test_current_schema_version_is_2(self) -> None:

+
+**Files:**

+# 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.

+- [ ] **Step 2: Run tests to verify they fail**
+
+```bash

+```
+
+Expected: all three FAIL (NFD title produces NFD path, assertion fails).
+
+- [ ] **Step 3: Add NFC normalization to `clean_filepath()`**
+
+In `src/documents/templating/filepath.py`, add `import unicodedata` at the top of the file and modify `clean_filepath()`:
+
+```python
+import unicodedata  # add to top-of-file imports
+
+class FilePathTemplate(Template):
+    def render(self, *args, **kwargs) -> str:
+        def clean_filepath(value: str) -> str:

+            2. Removing newlines and carriage returns
+            3. Removing extra spaces before and after forward slashes
+            4. Preserving spaces in other parts of the path
+            """
+            value = unicodedata.normalize("NFC", value)
+            value = value.replace("\n", "").replace("\r", "")
+            value = re.sub(r"\s*/\s*", "/", value)
+
+            # We remove trailing and leading separators, as these are always relative paths, not absolute, even if the user
+            # tries

+
+        original_render = super().render(*args, **kwargs)
+
+        return clean_filepath(original_render)
+```
+
+- [ ] **Step 4: Run tests to verify they pass**
+
+```bash
+uv run pytest --override-ini="addopts=" src/documents/tests/test_file_handling.py::TestFileHandling::test_generate_filename_nfc_normalizes_nfd_title src/documents/tests/test_file_handling.py::TestFileHandling::test_generate_filename_nfc_normalizes_nfd_correspondent src/documents/tests/test_file_handling.py::TestFileHandling::test_generate_filename_nfc_normalizes_raw_document_title_in_template -v
+```
+
+Expected: all three PASS.
+
+- [ ] **Step 5: Run the full file-handling test suite to check for regressions**
+
+```bash
+uv run pytest --override-ini="addopts=" src/documents/tests/test_file_handling.py -v
+```
+
+Expected: all existing tests continue to pass (ASCII titles are unaffected by NFC normalization).
+
+- [ ] **Step 6: Commit**
+
+```bash
+git add src/documents/templating/filepath.py src/documents/tests/test_file_handling.py
+git commit -m "Fix: normalize filesystem paths to NFC Unicode to prevent byte-level mismatches"
+```
+
+---
+
+## 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

+    """
+    return {
+        "title": pathvalidate.sanitize_filename(
+            unicodedata.normalize("NFC", document.title),

+        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="-",
+        ),

+        "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.

+# 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.

+
+In `src/documents/export/sinks.py`, change `ZipExportSink.__init__` to accept the new keyword-only params and store them, and pass them in `_open()`:
+
+```python

+## Task 3: Wire CLI flags + validation into `document_exporter`
+
+**Files:**
+
+- Modify: `src/documents/management/commands/document_exporter.py`
+- Test: `src/documents/tests/test_management_exporter.py`
+
+- [ ] **Step 1: Add the argparse flags**
+
+In `document_exporter.py`, add the import near the other `documents.export` import:
+
+```python
+from documents.export.compression import COMPRESSION_CHOICES
+from documents.export.compression import COMPRESSION_METHODS
+from documents.export.compression import compression_available
+from documents.export.compression import level_error
+from documents.export.compression import ZSTD
+```
+
+In `add_arguments`, after the `--zip-name` argument, add:
+
+```python
+        parser.add_argument(
+            "--zip-compression",
+            choices=COMPRESSION_CHOICES,

+        )
+```
+
+- [ ] **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

+```
+
+- [ ] **Step 3: Pass the resolved values into `ZipExportSink`**
+
+Change the `ZipExportSink(...)` construction in `handle()` to:
+
+```python
+        if self.zip_export:
+            sink = ZipExportSink(

+                delete=self.delete,
+            )

+- [ ] **Step 5: Run the tests**
+

+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.
+
+- [ ] **Step 7: Commit**
+
+```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:
+            - Import is attempted
+        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"`.
