Updates after reviewing and updating compat lirary

The library changed after these were written and more changes are already
decided upstream. Records what is wrong today, what to write toward, the
one question still open, and the fast-JSON-field trap, rather than
silently leaving code that would fail on contact.

+description: Use when integrating the whoosh-compat library into paperless-ngx search, replacing src/documents/search/_translate.py or _dates.py, building the search FieldRegistry, or changing user query parsing during the whoosh-to-tantivy transition
+---
+
+# whoosh-compat transition
+
+## Overview
+
+whoosh-compat (github.com/stumpylog/whoosh-compat; local checkout usually at `../whoosh-compat`) replaces the hand-maintained translation layer (`src/documents/search/_translate.py`, `_dates.py`): it parses user queries with a faithful fork of whoosh's real grammar into a typed AST and emits programmatic tantivy queries. Read its README and ARCHITECTURE.md before wiring anything; its DIVERGENCES.md lists intended behavior differences and is the authority on "is this difference a bug".
+
+## Decisions already made (do not re-derive)
+
+- **Queries are user-typed free text.** The advanced search box passes whatever the user types straight to the parser (that is how the issue #13568 queries exist). Do NOT try to infer the supported field surface from frontend code; the frontend only generates a few date filter strings, everything else is typed by users.
+- **The field surface is a policy decision, not `KNOWN_FIELDS`.** Today's `KNOWN_FIELDS` accepts internal ID fields (`tag_id`, `owner_id`, `viewer_id`, other `*_id`) that are undocumented in `docs/usage.md` and were ruled not user-searchable by the maintainer: exclude them from the `FieldRegistry` (they stay as programmatic permission/filter fields in `build_permission_filter`, which never touches user query text). The registry is built from documented syntax in `docs/usage.md` plus the v2-compat aliases (`type`, `path`, `type_id`-style aliases follow their canonical field's fate). Undocumented-but-working fields (`asn`, `page_count`, `num_notes`, `original_filename`, `checksum`) need an explicit maintainer yes/no; since users type freely, silently dropping one breaks any saved view using it, so a drop must be a visible, documented decision.
+- **Analyzer seam:** `FieldSpec.analyzer` binds the live registered tantivy analyzer's `.analyze` (the same Rust analyzer used at index time; language-keyed, so rebuild the registry when `SEARCH_LANGUAGE` changes, on the same trigger as `register_tokenizers`). `pattern_normalizer` is `_tokenizer.ascii_fold`: character-level lowercase+fold only, NEVER stemming.
+- **Diagnostics before emit:** `whoosh_compat.parse()` never raises on bad input. Check `ParseResult.diagnostics` and map to `SearchQueryError`/`InvalidDateQuery` (HTTP 400) BEFORE calling `emit()`; also catch the emitter's `UnsupportedQueryError` into a 400. Never carry forward the legacy raw-string fallback (`except Exception: query_str = raw_query`) into the new path; it masks integration bugs.
+- **Build typed errors from structured diagnostic data, never by parsing `message`.** Each `Diagnostic` carries `kind`, `startchar`/`endchar`, and `field`/`raw_value`. `message` is human-readable text whose wording can change. For a range that fails on one bound, `raw_value` is the bound that actually failed.
+  - `diagnostic.field` is a **`FieldRef`**, not a string: use `str(diagnostic.field)` for the canonical dotted name (`created`, `notes.user`) or `diagnostic.field.name` for the field alone. Note the name is canonical, so an aliased query (`type:`) reports the field it resolves to (`document_type`), and the diagnostic span covers the offending value rather than the field name, so the text the user typed for the field is not recoverable.
+- **The registry has one resolver.** `registry.make_ref(raw)` turns a raw field string into a `FieldRef` or `None` for an unknown field, and `registry.resolve(ref)` returns a `ResolvedField | None`, not a bare spec: read `.spec` for the `FieldSpec`, `.json_path` for the subpath (or `None`), `.is_subpath` and `.dotted_name` are convenience properties. There is no `resolve_json()`; a dotted name is interpreted only inside `make_ref`. Write `resolved = registry.resolve(ref)` then `resolved.spec.kind`, not `spec = registry.resolve(ref)` then `spec.kind`.
+- **`notes` and `custom_fields` are JSON fields** with fixed subpaths (`notes.user`/`notes.note`, `custom_fields.name`/`custom_fields.value`); the registry stays a static, language-keyed singleton, never per-request.
+- **`emit()`'s signature is `emit(node, *, index, registry)`, with no `schema` parameter.** Do not write a call site passing `schema=`. `emit()` calls the library's own `analyze()` pipeline stage internally (token analysis, multitoken resolution, zero-token drop), so paperless-ngx never needs to call `analyze()` itself.
+- **A wildcard/prefix pattern on a JSON subpath reports a parse-time diagnostic**, not a silent whole-field query: `custom_fields.value:abc*` reports `DiagnosticKind.UNSUPPORTED_PATTERN` (the same kind used for a wildcard on a numeric or BOOLEAN_EXISTS field) instead of matching against the wrong encoded bytes. Relevant here because `custom_fields.value` is exactly the kind of JSON subpath a user might expect to pattern-match; the error-mapping code needs a case for `UNSUPPORTED_PATTERN`, not just `BAD_DATE`/`BAD_NUMBER`.
+
+## Mandatory before deleting old code
+
+- Date-grammar parity audit, line by line: every keyword, relative unit, and abbreviation `_dates.py` and `_translate.py` accept today (including the whoosh-era abbreviations kept for old saved views) must have an accepted form in whoosh-compat's dateparse grammar. Silent keyword loss is the saved-view breakage class behind issue #13568.
+- Acceptance corpus compared by matched-document-ID sets, not query strings: the #13568 queries verbatim, real saved-view strings, every date keyword, field aliases, comma lists, date and numeric ranges, wildcards with bracket classes, boosts, JSON subpaths.
+
+## Tests: what goes, what comes
+
+Removed with their modules (do not port their string-level assertions):
+
+- `src/documents/tests/search/test_translate.py`: its subject is deleted; string-translation unit cases are whoosh-compat's own responsibility now. Cases that encode real user-visible behavior get reincarnated as result-level acceptance cases, not string assertions.
+- Date-keyword unit tests tied to `_dates.py` internals: same treatment.
+- `test_query.py` cases asserting `parse_user_query` internals or intermediate query strings: rewritten against the new pipeline, asserting on matched results.
+
+Kept: `test_migration_fulltext_query_field_prefixes.py` (data migration, orthogonal), `test_schema.py`, `test_tokenizer.py`, permission-filter and simple-search tests.
+
+Added:
+
+- A result-level acceptance module (paperless's analogue of whoosh-compat's `test_acceptance_e2e.py`): the corpus above against a real index built from `build_schema()`, asserting document-ID sets. Use `pytest.param(..., id="...")` for every case.
+- Registry unit tests: internal `*_id` names rejected, aliases resolve to canonical fields, JSON subpaths match `docs/usage.md`, construction deterministic per language.
+- One `Multitoken` case nested inside a top-level `OR` (whoosh-compat DIVERGENCES entry on Multitoken.DEFAULT) to prove it does not matter for paperless's data.
+- If acceptance work surfaces a new whoosh-compat divergence, that is a whoosh-compat-repo change (its `differential-triage` skill applies), not a silent paperless workaround.
+
+## Fast JSON field existence checks
+
+Existence checks against a fast JSON field work correctly, both whole-field (`notes:*`, which internally requires `json_subpaths=True`) and subpath-scoped (`custom_fields.value:*`, which checks only that subpath's own fast column). Both are covered by whoosh-compat's own test suite; see `DIVERGENCES.md` entry 20 for the exists-strategy design and its subpath-scoping note.
+
+Whether to mark `notes`/`custom_fields` fast is a paperless-ngx-side tradeoff (fast fields cost index size/build time for cheaper existence/range queries) independent of whoosh-compat's correctness — worth a maintainer decision, not assumed by this document.
+
+## Coordination
+
+- whoosh-compat is pre-1.0: pin an exact version or git SHA; upgrades are deliberate, reviewed changes.
+- JSON subpath emission depends on the installed tantivy-py version (fallback until quickwit-oss/tantivy-py#716 ships). The whoosh-compat repo has a `carve-out-retirement` skill; coordinate tantivy pin bumps with it, in a separate PR from the parser migration.
+- Rollout: no feature flag, no shadow-compare period. Safety comes from the date-grammar parity audit and the result-level acceptance corpus instead; `_translate.py`/`_dates.py` are deleted once those are green.
+
+## Common mistakes
+
+- Inferring the field surface from frontend code (users type queries directly).
+- Copying `KNOWN_FIELDS` into the registry wholesale (resurfaces internal fields).
+- Wiring stemming into `pattern_normalizer`.
+- Calling `emit()` unconditionally, or porting the legacy raw-string fallback.
+- Deleting `_dates.py` without the parity audit.
+- Porting `test_translate.py`'s string assertions instead of writing result-level tests.

+## Summary
+
+Replace paperless-ngx's hand-maintained query-translation layer
+(`src/documents/search/_translate.py`, `src/documents/search/_dates.py`)
+with [whoosh-compat](https://github.com/stumpylog/whoosh-compat): a typed
+Whoosh-grammar parser that emits programmatically constructed
+`tantivy.Query` objects instead of building an intermediate Tantivy query
+_string_. The integration point is narrow: `parse_user_query()` in
+`src/documents/search/_query.py` is the only function whose implementation
+changes; `_backend.py`, `_tokenizer.py`, simple/title search, CJK handling,
+and permission filtering are all unaffected.
+
+Delivered as a stack of four paperless-ngx PRs plus one prerequisite change
+in whoosh-compat itself (same maintainer, no cross-repo coordination
+overhead), landed with no feature flag and no shadow-compare rollout period
+— safety comes from a result-level acceptance test corpus and a
+date-grammar parity audit instead.

+
+Permission filtering is explicitly out of scope for this migration:
+`build_permission_filter()` builds its `tantivy.Query` directly against
+`owner_id`/`viewer_id`/`viewer_group_id`, never through the parser or
+registry, and those fields are exactly the internal `*_id` fields excluded
+from the `FieldRegistry` (see "Field surface" below). Nothing in this
+migration's diff touches it.
+
+## PR stack
+
+Each PR is independently buildable, reviewable, and CI-able; later PRs
+rebase on earlier ones. No PR depends on whoosh-compat behavior it hasn't
+already proven correct in isolation.
+
+1. **Refactor `_schema.py` to a shared field-definition table.** Pure
+   refactor — `build_schema()`'s output is byte-identical before and after.
+   `test_schema.py` (existing) proves it.
+2. **Pin whoosh-compat as a real dependency; build `FieldRegistry`.** New
+   `_registry.py` built from the same table PR 1 introduced. Registry unit
+   tests only — no wiring into search yet.
+3. **Date-grammar parity audit.** A transitional, executable differential
+   test using the still-present `_dates.py`/`_translate.py` as the oracle.
+   Any gap found is fixed in whoosh-compat directly before this PR closes.
+   A whoosh-compat PyPI release is expected around this point (see
+   "Dependency pinning").
+4. **Wire it in; delete the old path.** Rewrite `parse_user_query()`,
+   diagnostics→exception mapping, add the result-level acceptance corpus,
+   expand `test_api_search.py`, delete `_translate.py`/`_dates.py`/
+   `test_translate.py` and the internals-testing classes in `test_query.py`,
+   update `docs/usage.md` and changelog.
+
+`Diagnostic` carries `field: FieldRef | None` and `raw_value: str | None`,
+populated at its construction sites (`dateparse.py`'s `_error()`,
+`default.py`'s `BAD_NUMBER` sites), so paperless can build typed exceptions
+without parsing whoosh-compat's human-readable `message` text. `field` is a
+`FieldRef`, not a plain string; see the API reference at the top of this
+document.
+
+## Field surface
+
+The `FieldRegistry` covers only query-syntax-addressable fields — a subset
+of the full Tantivy schema. Internal-only schema fields with no query-syntax
+meaning of their own (`title_sort`/`correspondent_sort`/`type_sort` shadow
+sort fields, `bigram_*` CJK fields, `simple_title`/`simple_content`,
+`autocomplete_word`, `notes_text`) stay hardcoded `sb.add_*` calls in
+`_schema.py`, untouched by the shared table.
+
+**Decision: keep and document all five currently-undocumented-but-working
+fields** (`asn`, `page_count`, `num_notes`, `original_filename`,
+`checksum`) rather than dropping them — least risk of silently breaking an
+existing saved view. `docs/usage.md`'s advanced-search section gets these
+added with examples, as part of PR 4.
+
+**Decision: `archive_checksum` stays out of scope.** Unlike `checksum`, it
+isn't indexed in the Tantivy schema at all today (confirmed: `_schema.py`
+only adds `checksum`; `_build_tantivy_doc` only calls
+`doc.add_text("checksum", document.checksum)`). Making it searchable is a
+schema-level change (new indexed field, new document population code), not
+a parser-migration concern — left as a separate follow-up.
+
+**Decision: internal `*_id` fields (`tag_id`, `correspondent_id`,
+`document_type_id`, `storage_path_id`, `owner_id`, `viewer_id`,
+`viewer_group_id`) are excluded from the `FieldRegistry` entirely.** They
+remain Tantivy-schema-only, used exclusively by `build_permission_filter()`.
+Because whoosh-compat folds any unrecognized `field:` prefix into literal
+text (Whoosh-parity leniency, confirmed in `FieldsPlugin.do_fieldnames` —
+not an error), a saved view typed as `tag_id:5` won't 400: it silently
+becomes a text search for the literal string `tag_id:5`, most likely
+returning zero results. This is a real behavior change and gets a
+**changelog callout**, not just a docs update, since a docs addition alone
+wouldn't surface it to someone skimming release notes.
+
+## Shared field-definition table (`_fields.py`)
+
+```python
+from whoosh_compat import FieldKind  # reused directly — no parallel enum
+
+@dataclass(frozen=True, slots=True)
+class PublicField:
+    name: str
+    kind: FieldKind
+    aliases: tuple[str, ...] = ()
+    comma_values: bool = False
+    date_only: bool = False
+    fast: bool = False
+    subpaths: tuple[str, ...] = ()   # JSON kind only
+
+PUBLIC_FIELDS = (
+    PublicField("title", FieldKind.TEXT),
+    PublicField("content", FieldKind.TEXT),
+    PublicField("correspondent", FieldKind.TEXT),
+    PublicField("document_type", FieldKind.TEXT, aliases=("type",)),
+    PublicField("storage_path", FieldKind.TEXT, aliases=("path",)),
+    PublicField("original_filename", FieldKind.TEXT),
+    PublicField("tag", FieldKind.TEXT, comma_values=True),
+    PublicField("checksum", FieldKind.KEYWORD),
+    PublicField("asn", FieldKind.U64, fast=True),
+    PublicField("page_count", FieldKind.U64, fast=True),
+    PublicField("num_notes", FieldKind.U64, fast=True),
+    PublicField("created", FieldKind.DATE, date_only=True, fast=True),
+    PublicField("modified", FieldKind.DATETIME, fast=True),
+    PublicField("added", FieldKind.DATETIME, fast=True),
+    PublicField("notes", FieldKind.JSON, subpaths=("user", "note")),
+    PublicField("custom_fields", FieldKind.JSON, subpaths=("name", "value")),
+)
+```
+
+`build_schema()` derives its `sb.add_*` call and tokenizer from `kind`
+(TEXT/KEYWORD → `add_text_field` with `paperless_text`/`raw` tokenizer
+respectively; U64 → `add_unsigned_field`; DATE/DATETIME → `add_date_field`;
+JSON → `add_json_field`). The `notes_text` snippet-companion field stays a
+separate hardcoded line right after the `notes` entry — schema-only
+plumbing with no query-syntax meaning.
+
+`_registry.py` maps each `PublicField` to a `whoosh_compat.FieldSpec`,
+kept as one flat dataclass (no kind-specific subclassing) to mirror
+whoosh-compat's own `FieldSpec` design, which validates kind-conditional
+attributes (e.g. JSON requires non-empty `subpaths`) at
+`FieldRegistry.__init__` rather than in the type system.
+
+Footnote for whoever writes `_registry.py`: `FieldRegistry.__init__` forces
+`date_only=True` on _any_ `FieldKind.DATE` spec regardless of what's
+passed, unconditionally — `PublicField.date_only` isn't an independent
+knob for DATE fields the way it might look; it only matters in the sense
+that `created` sets it explicitly for clarity, while `modified`/`added`
+use `FieldKind.DATETIME` instead of relying on that override.
+
+**`PublicField.subpaths` stays `tuple[str, ...]`, not a nested structure.**
+Confirmed against whoosh-compat's own `FieldRegistry.make_ref()`: it splits a
+dotted query term on the _first_ dot only and matches the remainder as an
+exact string against `spec.subpaths` — even the docstring's own
+`"metadata.author.name"` example is a single opaque string in the tuple,
+not a recursive tree. (`FieldSpec.subpaths` itself now stores a `Mapping[str,
+SubpathSpec]` internally, normalized from whatever tuple is passed at
+construction; that's an implementation detail of `FieldSpec.__post_init__`,
+not something `PublicField`'s own table needs to mirror — passing a plain
+tuple into `FieldSpec(..., subpaths=...)` still works exactly as written
+here.) A tuple of strings is exactly as expressive as the library it feeds;
+inventing richer structure in `PublicField` now would just get flattened
+back to strings at the registry-construction boundary. Real recursive
+nesting, if ever needed, is new whoosh-compat capability first (the
+per-subpath `SubpathSpec` container exists specifically to make that a
+later, additive change).
+
+**JSON document population stays separate from `subpaths`.** `subpaths` is
+query-side only — it declares which dotted names are legal to type and
+which JSON keys the emitter should address. It says nothing about how
+`_backend.py::_build_tantivy_doc` builds the JSON documents at index-write
+time, and that logic isn't uniform attribute access (`note.user.username`
+needs a null guard and isn't `note.user`; `cfi.value_for_search` is a
+property, not a literal `value` attribute), so a generic
+`getattr(obj, subpath_name)` scheme would silently do the wrong thing for
+both. That code stays hand-written, unchanged by this migration. Mitigation
+instead: a coupling test (PR 2, alongside the registry unit tests) asserting
+the literal JSON keys used in `_build_tantivy_doc`'s `doc.add_json(...)`
+calls match `PUBLIC_FIELDS`' `notes`/`custom_fields` `subpaths` exactly, so
+drift between the two is caught rather than silently becoming an
+unqueryable (or silently unindexed) field.
+
+**JSON subpath queries (`notes.*`, `custom_fields.*`) route through
+`index.parse_query()`, not programmatic construction, given paperless's
+pinned tantivy version.** Installed `tantivy-py`'s `Query.term_query`
+cannot resolve a JSON subpath by exact field name — it raises as if the
+field didn't exist. Until
+[tantivy-py#716](https://github.com/quickwit-oss/tantivy-py/pull/716) lands
+and ships, whoosh-compat's `TantivyEmitter._json_paths_supported()` feature-
+detects this per process and falls back to a strictly escaped, single-leaf
+`index.parse_query()` call for just that one leaf (whoosh-compat's README/
+ARCHITECTURE.md call this out as "the JSON subpath carve-out"). Paperless
+pins `tantivy~=0.26.0`, squarely inside the affected range (whoosh-compat's
+`tantivy` extra only requires `tantivy>=0.24`, so nothing prevents this
+combination). Nothing needs to change in this design because of it — the
+carve-out is self-retiring on whoosh-compat's side once tantivy-py catches
+up — but the acceptance corpus's `notes.user:`/`custom_fields.name:` cases
+(PR 4) are exercising that fallback escaping path specifically, not the
+programmatic path every other field goes through, and that's worth knowing
+if one of those cases ever behaves oddly around quoting/escaping. A
+multi-token JSON subpath value with `Multitoken.AND`/`OR` now gets correct
+combinator semantics through this fallback (each token becomes its own
+`index.parse_query()`-backed leaf, `Must`/`Should`-combined normally,
+instead of collapsing into one space-joined phrase-shaped query); a genuine
+quoted phrase on a JSON subpath still cannot carry an explicit slop through
+this fallback (silently ignored, `~N` has no effect) until the carve-out
+retires. Also worth knowing given `custom_fields.value` is JSON: this
+fallback's `index.parse_query()` call gives a JSON subpath term free
+numeric/boolean type inference tantivy's own query grammar provides (a
+query like `custom_fields.value:100` matches both a stored JSON number `100`
+and a stored JSON string `"100"`); the future programmatic path (once
+tantivy-py#716 ships) has no equivalent union and would need this
+re-evaluated for numeric/boolean custom field values specifically
+(whoosh-compat's `DIVERGENCES.md` entry 22 tracks this open question).
+
+**Analyzer wiring**: `FieldSpec.analyzer` reuses the same `tantivy
+.TextAnalyzer` objects `_tokenizer.py` already builds (`_paperless_text
+(language)`, etc.) — standalone objects not dependent on index
+registration, so `_registry.py` calls the same builder functions and binds
+`.analyze` directly; `checksum` (KEYWORD, `raw` tokenizer) gets an identity
+analyzer (`lambda t: [t]`). `pattern_normalizer` for every field is
+`_tokenizer.ascii_fold` (character-fold only, never stemming) per the
+skill's explicit instruction. The whole `FieldRegistry` is built once,
+cached keyed by `settings.SEARCH_LANGUAGE`, rebuilt on the same trigger
+`register_tokenizers()` already uses.

+```
+
+No `except Exception: query_str = raw_query` fallback — per the skill, that
+legacy defensive branch is explicitly not carried forward. A bug in the new
+path must surface as a real error, not silently degrade to stale behavior.
+
+`views.py`'s existing `except SearchQueryError as e: raise
+ValidationError({"query": [str(e)]}) from e` handler gets one added branch
+to surface every aggregated message instead of just one:
+
+```python
+except SearchQueryError as e:
+    messages = [str(sub) for sub in e.errors] if isinstance(e, MultipleSearchQueryErrors) else [str(e)]
+    raise ValidationError({"query": messages}) from e
+```
+
+`d.field`/`d.raw_value` are populated for `BAD_DATE` and `BAD_NUMBER`
+diagnostics; if either is `None` for a diagnostic kind that doesn't populate
+them, `_single_diagnostic_to_error`'s fallthrough to
+`SearchQueryError(d.message)` still applies.
+
+Deferred, explicitly out of scope for this PR stack: any frontend use of
+`startchar`/`endchar` (already present on `Diagnostic` today) to highlight
+the offending span in the search box. Backend-only for now, per explicit
+decision.

+
+New tests per PR:
+
+- **PR 2**: `test_registry.py` — internal `*_id` names rejected; `type`/
+  `path` aliases resolve to canonical fields; JSON subpaths match
+  `docs/usage.md`; registry construction deterministic per language; the
+  `notes`/`custom_fields` dict-key coupling test described above.
+- **PR 3**: `test_date_grammar_parity.py` — transitional, parametrized over
+  every keyword/unit `_dates.py`/`_translate.py` accept today
+  (`_DATE_KEYWORDS`, all of `_UNIT_ALIASES`'s Whoosh-era abbreviations —
+  `yrs`/`mos`/`wks`/`hrs`/`mins`/`secs` etc. — digit-precision forms, ISO
+  dash forms, `now-7d`/`now+1h`/`now-30m` compact offsets, open/reversed
+  ranges). Each case parses through `wc.parse()` against a DATE-kind
+  `FieldRegistry` and asserts no diagnostics come back — a coverage check
+  only (does whoosh-compat accept this input at all), not a check on the
+  bounds or AST shape it parses to, which is whoosh-compat's own
+  differential-testing responsibility against a real whoosh oracle, not
+  something to re-verify here against `_translate.py` as a second, weaker
+  oracle. If the team wants confidence that actual search _behavior_ at a
+  given keyword didn't change, that belongs in the PR 4 result-level
+  acceptance corpus (real indexed documents at date boundaries, matched-ID
+  assertions), not an AST/bounds comparison.
+  Deleted again in PR 4 along with the legacy code it audits, superseded by
+  the permanent acceptance corpus. This audit is scoped to _parity_ only —
+  whoosh-compat's date grammar is a strict superset of what `_dates.py`
+  accepts today (e.g. `tomorrow`, `now`, `midnight`, `noon`, weekday names
+  like `next monday`), so the migration also grants new date vocabulary for
+  free. That's a nice side effect, not something this PR needs to test or
+  document beyond noting it in the changelog alongside the other behavior
+  changes.
+- **PR 4**:
+  - Result-level acceptance module (paperless's analogue of whoosh-compat's
+    `test_acceptance_e2e.py`): a real index built via `build_schema()`, the
+    issue #13568 queries verbatim, real saved-view strings, every date
+    keyword/unit, field aliases, comma lists, numeric/date ranges,
+    bracket-class wildcards, boosts, JSON subpaths — asserted by matched
+    document-ID set, `pytest.param(..., id=...)` per case. Plus a
+    multi-diagnostic case (two bad fields → `MultipleSearchQueryErrors`
+    with both messages present) and one `Multitoken` case nested inside a
+    top-level `OR` (proves DIVERGENCES entry 15 doesn't matter for
+    paperless's data, per the skill).
+  - `test_api_search.py` expanded: a multi-bad-field query (e.g.
+    `created:notadate AND asn:notanumber`) asserting the 400 response's
+    `query` list contains both messages; end-to-end searches on the five
+    newly-documented fields (`asn:`, `page_count:`, `num_notes:`,
+    `original_filename:`, `checksum:`) returning the right documents
+    through the real index.
+
+## Dependency pinning
+
+Stays `path = "../whoosh-compat"` in `[tool.uv.sources]` through the whole
+PR stack — both repos are being actively co-developed. The final swap
+happens at PR 4:
+
+- **Primary plan**: whoosh-compat is released to PyPI around PR 3 (per
+  your stated intent), assuming the parity audit doesn't turn up anything
+  needing a second round. PR 4 switches to a pinned PyPI version
+  (`whoosh-compat[tantivy]==X.Y.Z` in `dependencies`, the
+  `[tool.uv.sources]` override removed entirely).
+- **Fallback**: if the PyPI release slips past PR 4's start, pin an exact
+  git commit SHA instead (`whoosh-compat[tantivy] @ git+https://github.com/
+stumpylog/whoosh-compat@<sha>`), per the skill's "pre-1.0: pin an exact
+  version or git SHA, upgrades are deliberate" guidance.
+
+The `TODO` comment already sitting in `pyproject.toml` (from the earlier
+smoke-test setup) gets updated to reflect this — "release, else pinned SHA"
+— rather than committing hard to one path before it's known which applies.
+
+## Explicitly out of scope
+
+- `archive_checksum` indexing/search (separate schema-level follow-up).
+- Frontend consumption of `Diagnostic.startchar`/`endchar` for in-box error
+  highlighting (backend-only for this PR stack).
+- A feature flag or shadow-compare rollout period — explicitly decided
+  against; safety comes from the acceptance corpus and parity audit instead.
+- Any change to `build_permission_filter()`/`_apply_permission_filter()` —
+  confirmed untouched by this migration.
