Adds the extensibility design that hoists the bulk-edit operation
definition (today smeared across serialisers.py, views.py, bulk_edit.py
and keyed three different ways) behind a BulkEditOperation registry +
PermissionRequirements value object, with per-operation OpenAPI examples.
Contract-preserving refactor; both docs reviewed across multiple passes
(permission matrix verified, both view call sites accounted for).

Replace the search-error-shapes stub with a full design spec and a TDD
implementation plan for friendlier advanced-search error messages.
Empirically validated against a live Tantivy index: three error families
(UnknownFieldError, InvalidFieldValueError, MalformedQueryError),
proactive numeric validation plus a parse_query backstop, comparison
operators confirmed working, and a parse-based field drift guard.

* Chore(beta): add sqlite-vec 0.1.9 dependency
Pinned exactly: the 0.1.9 wheels carry no baked SIMD flags (safe on
pre-AVX2 CPUs, the point of this migration); the 0.1.10 alphas bake
-mavx and would reintroduce the #12970 crash class.

* Test(beta): port vector store tests to sqlite-vec backend
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Enhancement(beta): switch AI vector store from LanceDB to sqlite-vec
Fixes the non-AVX2 SIGILL class (#12970) at the root: lancedb is no
longer imported. sqlite-vec 0.1.9 wheels carry no baked SIMD, vec0
metadata columns give parameterized EQ/IN filtering, WAL preserves the
lock-free-reader model, and compact() rebuilds the table because vec0
DELETEs never reclaim space.
Implementation notes vs. the Task 3A draft:
- compact() uses a file-swap approach (new db file + Path.replace) rather
than ALTER TABLE RENAME, which does not cascade to shadow tables in
sqlite-vec 0.1.9 (upstream limitation).
- Bloat is tracked via a cumulative total_inserts counter in index_meta
because the _rowids shadow table does not accumulate deleted rows in
0.1.9 (contrary to the design doc assumption from #54).
- None distances from the zero-vector cosine edge case are mapped to
similarity 0.0 rather than raising TypeError.
- Test suite updated accordingly: _bloat_ratio reads index_meta instead
of _rowids; seed collision in force-compact test fixed (seed=100.0).

* Enhancement(beta): add schema migration machinery to sqlite-vec vector store
Adds versioned schema migration support modelled after PR #12968's LanceDB
approach, adapted for sqlite-vec's file-swap compaction pattern.
- SCHEMA_VERSION = 1 written to index_meta at table creation and preserved
through compact()
- Migration dataclass with from_version, to_version, kind ("structural" or
"re-embed"), description, and an optional apply(src, dst, dim) callable
- MIGRATIONS registry (empty at v1 baseline); add entries and bump
SCHEMA_VERSION when the schema changes
- check_and_run_migrations(): structural migrations run via the same
file-swap as compact() (no re-embed); re-embed migrations return True
so the caller forces a full rebuild
- update_llm_index() calls check_and_run_migrations() under the write lock
before any indexing work

* Chore(beta): deduplicate vector store internals via helper methods
Extract three helpers to remove copy-paste between compact() and
_run_structural_migration():
- _meta_set_on(conn, key, value): static upsert into any connection's
index_meta; _meta_set() now delegates to it
- _create_vec_table(conn, dim): CREATE VIRTUAL TABLE DDL (carries the
nosemgrep annotation)
- _swap_in_compact(compact_path, db_path): close/replace/reconnect
sequence used by both file-swap callers
Also normalises compact() error-path cleanup to unlink(missing_ok=True).

* Adds equality test and no covers some defensive error handling stuff
* Ensures an embed migration stops the migration chain, just in case
* Silence one kind right but not really semgrep
* Trims dead assignment
* Fix(beta): address Copilot review on sqlite-vec vector store
Three findings from the PR review:
- compact() failure cleanup now unlinks the temporary .compact-wal and
.compact-shm files, matching _run_structural_migration(); previously
only the main .compact file was removed.
- _build_where() fails closed (1 = 0) when filters are requested but none
translate, instead of emitting "()" which is invalid SQL; filters scope
document access, so an empty translation must match no rows.
- Drop the unused table_name constructor parameter (all SQL hardcodes
DEFAULT_TABLE_NAME) and its callers in indexing.py.
Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
* Enhancement(beta): guard sqlite-vec compaction swap against concurrent readers
The compaction/migration file swap replaces the database via os.replace,
but the -wal/-shm files are keyed by path, not inode. A reader holding an
open connection across the swap leaves the old WAL aliased onto the new
file; a subsequent write then corrupts the database (reproduced via
PRAGMA integrity_check).
Add a cross-process read/write lock (filelock.ReadWriteLock) over the
index:
- read_store() holds it shared for the whole connection lifetime (and
closes the connection on exit); concurrent readers do not block.
- compaction and the migration check run under an exclusive lock that
drains readers, and skip with an info log on Timeout (maintenance op,
retries next run).
- Normal writes are untouched: WAL gives reader/writer concurrency and
LLM_INDEX_LOCK still serializes writers, so they never block readers.
load_or_build_index() now takes the store from the caller's read_store()
so the lock and connection span the whole retrieval; chat holds it across
the streamed response. Two new settings: LLM_INDEX_RWLOCK and
LLM_INDEX_COMPACTION_LOCK_TIMEOUT.

* Fix: Move LLM index lock outside index dir and skip per-doc tasks on bulk update
Two concurrency bugs from #12893:
[P1] Lock file lived inside LLM_INDEX_DIR. A rebuild calls
shutil.rmtree(LLM_INDEX_DIR), deleting the lock while a worker still
held it. A second worker then acquired a fresh lock on the new path and
ran concurrently, defeating serialisation. Move the lock to
DATA_DIR/locks/llm_index.lock (a new settings constant LLM_INDEX_LOCK)
so rmtree cannot touch it. The locks/ dir is created at settings load
time, matching the existing pattern for LOGGING_DIR.
[P2] document_updated was connected to add_or_update_document_in_llm_index
in apps.py. bulk_update_documents() emits document_updated for every
document in the batch, queuing N per-document LLM tasks, and then also
calls update_llm_index(rebuild=False) once at the end. Pass
skip_ai_index=True when sending document_updated from the bulk path so
the handler skips the per-document enqueue; the existing batch call at
the end of bulk_update_documents is the only LLM update for that path.

* Fix: ghost vectors leave KeyError-prone nodes_dict entries after deletion
docstore.delete_document() removes a node from the docstore but leaves its
entry in index_struct.nodes_dict (the FAISS positional-id to node-UUID map).
A subsequent similarity query resolves the ghost position to the deleted UUID,
finds nothing in fetched_nodes_by_id, and raises KeyError inside
_insert_fetched_nodes_into_query_result.
Purge stale nodes_dict entries after each docstore deletion and re-sync the
mutated index_struct into the kvstore so persist() writes the updated mapping.
Dead FAISS vectors remain in the flat index until the next full rebuild
(IndexFlatL2 is append-only); add a try/except KeyError around
retriever.retrieve() as a defensive fallback for any residual ghost positions.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix: acquire index lock in query_similar_documents
query_similar_documents() loaded the index and ran the FAISS retriever
without holding the file lock. All write paths (update_llm_index,
llm_index_add_or_update_document, llm_index_remove_document) hold
FileLock(_index_lock_path()), so a concurrent rebuild calling
shutil.rmtree(LLM_INDEX_DIR) while a read is mid-load produces an IOError
or corrupt partial state.
Wrap the load_or_build_index() call and all subsequent retriever work inside
FileLock. The early-return guards (vector_store_file_exists check, empty
allowed_document_ids) remain outside the lock; the DB query for the final
result set also stays outside.

* Fix: skip LLM index enqueue on document_updated during version addition
When a document is consumed as a new version of an existing document, the
consumer fires document_consumption_finished (which triggers
add_or_update_document_in_llm_index) and then document_updated for the root
document. Both signals are connected to the same handler, so the root document
was enqueued for LLM indexing twice per version-addition event.
Pass skip_ai_index=True on the consumer's version-addition document_updated
send so the handler's existing guard suppresses the duplicate enqueue.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Test: bulk_update_documents must not enqueue per-doc LLM tasks
With AI enabled, bulk_update_documents() sends document_updated for every
document in the batch. The skip_ai_index=True kwarg (added in the P2 fix)
prevents add_or_update_document_in_llm_index from enqueuing a per-document
task for each one. Only the single update_llm_index call at the end should run.

* Fix: Remove all nodes for multi-chunk documents in update_llm_index incremental path
The existing_nodes dict comprehension keyed on document_id silently dropped all
but the last node per document, so only that one node was deleted when a
modified document was re-indexed, leaving all other chunks as ghost vectors in
the FAISS index. Switch to a defaultdict(list) that collects every node per
document_id, then iterate and delete all of them before inserting fresh nodes.

* Fix: Wire document_updated signal to LLM index update handler

document_consumption_finished behavior.

* Fix: Add file lock around FAISS index mutations to prevent concurrent write corruption
Two concurrent Celery workers calling llm_index_add_or_update_document or
llm_index_remove_document each loaded the same on-disk index independently,
made their own change, and the last writer silently overwrote the first's
update. Wrap both functions and the rebuild/persist body of update_llm_index
in a filelock.FileLock keyed on LLM_INDEX_DIR/index.lock. Add a TOCTOU
comment on queue_llm_index_update_if_needed explaining the residual risk
(duplicate rebuild tasks are wasteful but not corrupting because the lock
serialises the actual write).

* Fix: Apply _normalize() in extract_unmatched_names to prevent duplicate suggestions
extract_unmatched_names was using .lower() while _match_names_to_queryset

unmatched list, causing duplicate object creation.

* Fix: Skip LLM index update gracefully when document has no indexable content
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix: Persist empty index when all documents are deleted to clear stale FAISS vectors
The early-return guard in update_llm_index fired before persist() when no
documents existed, leaving a stale on-disk FAISS index that returned phantom
hits for deleted document IDs. Now the guard only returns early for the
incremental (rebuild=False) path when no index exists on disk; the rebuild
path always continues through to persist(), producing an empty clean index.

* Replaces loaddata with streaming bulk_create
Replaces call_command('loaddata') with a streaming implementation that
reads manifest records one at a time via ijson, accumulates per-model
batches up to --batch-size, and flushes via bulk_create. This reduces
peak memory and no longer scales directly with the size of the import.
* fix(importer): avoid guardian lru_cache poisoning; include M2M through tables in check_constraints
clear_cache() inside the import transaction emptied Django's ContentType
manager cache while fixture PKs were live, causing downstream ContentType
lookups to repopulate guardian's separate @lru_cache(None) with
fixture-PK objects. After the TestCase transaction rolled back to
original PKs, guardian's lru_cache held stale fixture ContentType
objects, causing MixedContentTypeError in unrelated subsequent tests.
Remove clear_cache() since it was defending against a theoretical
stale-cache scenario that doesn't occur in a proper same-install restore.
Fix check_constraints() to explicitly include auto-created M2M through
tables (populated by .set() after bulk_create) alongside the model tables,
addressing the gap where join-table FK violations would have gone
undetected.

redundantly writing status and date_done. task_failure_handler now
computes duration_seconds and wait_time_seconds so failed tasks get
complete timing data. This eliminates a wasted .get() + .save() round
trip on every failed task and gives each handler a clean, non-overlapping
responsibility.

* fix(tasks): resolve trigger_source header via TriggerSource enum lookup
Replace two hardcoded string comparisons ("scheduled", "system") with a
single TriggerSource(header_source) lookup so the enum values are the
single source of truth. Any valid TriggerSource DB value passed in the
header is accepted; invalid values fall through to the document-source /
MANUAL logic. Update tests to pass enum values in headers rather than raw
strings, and add a test for the invalid-header fallback path.

* fix(tasks): use TriggerSource enum values at all apply_async call sites
Replace raw strings ("system", "manual") with PaperlessTask.TriggerSource
enum values in the three callers that can import models. The settings
file remains a raw string (models cannot be imported at settings load
time) with a comment pointing to the enum value it must match.

* test(tasks): parametrize repetitive test cases in task test files
test_api_tasks.py:
- Collapse six trigger_source->v9-type tests into one parametrized test,
adding the previously untested API_UPLOAD case
- Collapse three task_name mapping tests (two remaps + pass-through)
into one parametrized test
- Collapse two acknowledge_all status tests into one parametrized test
- Collapse two run-endpoint 400 tests into one parametrized test
- Update run/ assertions to use TriggerSource enum values
test_task_signals.py:
- Collapse three trigger_source header tests into one parametrized test
- Collapse two DocumentSource->TriggerSource mapping tests into one
parametrized test
- Collapse two prerun ignore-invalid-id tests into one parametrized test
All parametrize cases use pytest.param with descriptive ids.

* refactor: switch consumer and callers to ParserRegistry (Phase 4)
Replace all Django signal-based parser discovery with direct registry
calls. Removes `_parser_cleanup`, `parser_is_new_style` shims, and all
old-style isinstance checks. All parser instantiation now uses the
`with parser_class() as parser:` context manager pattern.
- documents/parsers.py: delegate to get_parser_registry(); drop lru_cache
- documents/consumer.py: use registry + context manager; remove shims
- documents/tasks.py: same pattern
- documents/management/commands/document_thumbnails.py: same pattern
- documents/views.py: get_metadata uses context manager
- documents/checks.py: use get_parser_registry().all_parsers()
- paperless/parsers/registry.py: add all_parsers() public method
- tests: update mocks to target documents.consumer.get_parser_class_for_mime_type
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* refactor: drop get_parser_class_for_mime_type; callers use registry directly
All callers now call get_parser_registry().get_parser_for_file() with
the actual filename and path, enabling score() to use file extension
hints. The MIME-only helper is removed.
- consumer.py: passes self.filename + self.working_copy
- tasks.py: passes document.original_filename + document.source_path
- document_thumbnails.py: same pattern
- views.py: passes Path(file).name + Path(file)
- parsers.py: internal helpers inline the registry call with filename=""
- test_parsers.py: drop TestParserDiscovery (was testing mock behavior);
TestParserAvailability uses registry directly
- test_consumer.py: mocks switch to documents.consumer.get_parser_registry
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* refactor: remove document_consumer_declaration signal infrastructure
Remove the document_consumer_declaration signal that was previously used
for parser registration. Each parser app no longer connects to this signal,
and the signal declaration itself has been removed from documents/signals.
Changes:
- Remove document_consumer_declaration from documents/signals/__init__.py
- Remove ready() methods and signal imports from all parser app configs
- Delete signal shim files (signals.py) from all parser apps:
- paperless_tesseract/signals.py
- paperless_text/signals.py
- paperless_tika/signals.py
- paperless_mail/signals.py
- paperless_remote/signals.py
Parser discovery now happens exclusively through the ParserRegistry
system introduced in the previous refactor phases.

* refactor: remove empty paperless_text and paperless_tika Django apps
After parser classes were moved to paperless/parsers/ in the plugin
refactor, these Django apps contained only empty AppConfig classes
with no models, views, tasks, migrations, or other functionality.
- Remove paperless_text and paperless_tika from INSTALLED_APPS
- Delete empty app directories entirely
- Update pyproject.toml test exclusions
- Clean stale mypy baseline entries for moved parser files
paperless_remote app is retained as it contains meaningful system
checks for Azure AI configuration.

* Moves the checks and tests to the main application and removes the old applications
* Adds a comment to satisy Sonar
* refactor: remove automatic log_summary() call from get_parser_registry()
The summary was logged once per process, causing it to appear repeatedly
during Docker startup (management commands, web server, each Celery
worker subprocess). External parsers are already announced individually
at INFO when discovered; the full summary is redundant noise.
log_summary() is retained on ParserRegistry for manual/debug use.

* Refactor RasterisedDocumentParser to ParserProtocol interface
- Add RasterisedDocumentParser to registry.register_defaults()
- Update parser class: remove DocumentParser inheritance, add Protocol
class attrs/classmethods/properties, context-manager lifecycle
- Add read_file_handle_unicode_errors() to shared parsers/utils.py
- Replace inline unicode-error-handling with shared utility call
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Update tesseract signals.py to import from new parser location
RasterisedDocumentParser moved to paperless.parsers.tesseract; update
the lazy import in signals.get_parser so the signal-based consumer
declaration continues to work during the registry transition. Pop
logging_group and progress_callback kwargs for constructor compatibility.

* tests: rewrite test_tesseract_parser to pytest style with typed fixtures
- Converts all tests from Django TestCase to pytest-style classes
- Adds tesseract_samples_dir, null_app_config, tesseract_parser, and
make_tesseract_parser fixtures in conftest.py; all DB-free except
TestOcrmypdfParameters which uses @pytest.mark.django_db
- Defines MakeTesseractParser type alias in conftest.py for autocomplete
- Fixes FBT001 (boolean positional args) by making bool params
keyword-only with * separator in parametrize test signatures
- Adds type annotations to all fixture parameters for IDE support
- Uses pytest.param(..., id="...") throughout; pytest-mock for patching
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* fix(types): fully annotate paperless/parsers/tesseract.py
Fixes all mypy and pyrefly errors in the new parser file:
- Add missing type annotations to is_image, has_alpha, get_dpi,
calculate_a4_dpi, construct_ocrmypdf_parameters, post_process_text
- Narrow Path-only (no str) for image helper args; convert to str when
building list[str] args for run_subprocess
- Annotate ocrmypdf_args as dict[str, Any] so operator expressions on
its values type-check and ocrmypdf.ocr(**args) resolves cleanly
- Declare text: str | None = None at top of extract_text to unify
all assignments to the same type across both branches
- Import Any from typing
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fixes isort
* fix: add RasterisedDocumentParser to new-style parser shim checks
The new RasterisedDocumentParser uses __enter__/__exit__ for resource
management instead of cleanup(). Update all existing new-style shims to
include it in the isinstance checks:
- documents/consumer.py: _parser_cleanup(), parser_is_new_style
- documents/tasks.py: parser_is_new_style, finally cleanup branch
(also adds RemoteDocumentParser which was missing from the latter)
- documents/management/commands/document_thumbnails.py: adds new-style
handling from scratch (enter/exit + 2-arg get_thumbnail signature)
Fix stale import paths in three test files that were still importing
from paperless_tesseract.parsers instead of paperless.parsers.tesseract.
Fix two registry tests that used application/pdf as a proxy for "no
handler" — now that RasterisedDocumentParser is registered, PDF always
has a handler, so switch to a truly unsupported MIME type.
Signal infrastructure and shims remain intact; this is plumbing only.

* Refactor(mail): move mail parser tests to paperless/tests/parsers/
Move test_parsers.py → test_mail_parser.py and test_parsers_live.py →
test_mail_parser_live.py alongside the other built-in parser tests,
preserving git history before editing. Update MailDocumentParser import

* Chore: move mail parser sample files to paperless/tests/samples/mail/
Relocate all mail test fixtures from src/paperless_mail/tests/samples/ to
src/paperless/tests/samples/mail/ ahead of the parser plugin refactor.
Add the new path to the codespell skip list to prevent false-positive
spell corrections in binary/fixture email files.

* Feat(tests): add mail parser fixtures to paperless/tests/parsers/conftest.py

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Feat(parsers): migrate MailDocumentParser to ParserProtocol
Move the mail parser from paperless_mail/parsers.py to
paperless/parsers/mail.py and refactor it to implement ParserProtocol:
- Class-level name/version/author/url attributes
- supported_mime_types() and score() classmethods (score=20)
- can_produce_archive=False, requires_pdf_rendition=True
- Context manager lifecycle (__enter__/__exit__)
- New parse() signature without mailrule_id kwarg; consumer sets
parser.mailrule_id before calling parse() instead
- get_text()/get_date()/get_archive_path() accessor methods
- extract_metadata() returning email headers and attachment info
Register MailDocumentParser in the ParserRegistry alongside Text and
Tika parsers. Update consumer, signals, and all import sites to use
the new location. Update tests to use the new accessor API, patch
paths, and context-manager fixture.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix(parsers): pop legacy constructor args in mail signal wrapper
MailDocumentParser.__init__ takes no constructor args in the new
protocol. Update the get_parser() signal wrapper to pop logging_group
and progress_callback (passed by the legacy consumer dispatch path)
before instantiating — the same pattern used by TextDocumentParser.
Also update test_mail_parser_receives_mailrule to use the real signal
wrapper (mail_get_parser) instead of MailDocumentParser directly, so
the test exercises the actual dispatch path and matches the new
parse() call signature (no mailrule kwarg).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Bumps this so we can run
* Fixes location of the fixture
* Removes fixtures which were duplicated
* Feat(parsers): add ParserContext and configure() to ParserProtocol
Replace the ad-hoc mailrule_id attribute assignment with a typed,
immutable ParserContext dataclass and a configure() method on the
Protocol:
- ParserContext(frozen=True, slots=True) lives in paperless/parsers/
alongside ParserProtocol and MetadataEntry; currently carries only
mailrule_id but is designed to grow with output_type, ocr_mode, and
ocr_language in a future phase (decoupling parsers from settings.*)
- ParserProtocol.configure(context: ParserContext) -> None is the
extension point; no-op by default
- MailDocumentParser.configure() reads mailrule_id into _mailrule_id
- TextDocumentParser and TikaDocumentParser implement a no-op configure()
- Consumer calls document_parser.configure(ParserContext(...)) before
parse(), replacing the isinstance(parser, MailDocumentParser) guard
and the direct attribute mutation
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Feat(parsers): call configure(ParserContext()) in update_document task
Apply the same new-style parser shim pattern as the consumer to
update_document_content_maybe_archive_file:
- Call __enter__ for Text/Tika parsers after instantiation
- Call configure(ParserContext()) before parse() for all new-style parsers
(mailrule_id is not available here — this is a re-process of an
existing document, so the default empty context is correct)
- Call parse(path, mime_type) with 2 args for new-style parsers
- Call get_thumbnail(path, mime_type) with 2 args for new-style parsers
- Call __exit__ instead of cleanup() in the finally block
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix(tests): add configure() to DummyParser and missing-method parametrize
ParserProtocol now requires configure(context: ParserContext) -> None.
Update DummyParser in test_registry.py to implement it, and add
'missing-configure' to the test_partial_compliant_fails_isinstance
parametrize list so the new method is covered by the negative test.

* Refactor: move remote parser, test, and sample to paperless.parsers
Relocates three files to their new homes in the parser plugin system:
- src/paperless_remote/parsers.py
→ src/paperless/parsers/remote.py
- src/paperless_remote/tests/test_parser.py
→ src/paperless/tests/parsers/test_remote_parser.py
- src/paperless_remote/tests/samples/simple-digital.pdf
→ src/paperless/tests/samples/remote/simple-digital.pdf
Content and imports will be updated in the follow-up commit that
rewrites the parser to the new ParserProtocol interface.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Feature: migrate RemoteDocumentParser to ParserProtocol interface
Rewrites the remote OCR parser to the new plugin system contract:
- `supported_mime_types()` is now a classmethod that always returns the
full set of 7 MIME types; the old instance-method hack (returning {}
when unconfigured) is removed
- `score()` classmethod returns None when no remote engine is configured
(making the parser invisible to the registry), and 20 when active —
higher than the tesseract default of 10 so the remote engine takes
priority when both are available
- No longer inherits from RasterisedDocumentParser; inherits no parser
class at all — just implements the protocol directly
- `can_produce_archive = True`; `requires_pdf_rendition = False`
- `_azure_ai_vision_parse()` takes explicit config arg; API client
created and closed within the method
- `get_page_count()` returns the PDF page count for application/pdf,
delegating to the new `get_page_count_for_pdf()` utility
- `extract_metadata()` delegates to `extract_pdf_metadata()` for PDFs;
returns [] for all other MIME types
New files:
- `src/paperless/parsers/utils.py` — shared `extract_pdf_metadata()` and
`get_page_count_for_pdf()` utilities (pikepdf-based); both the remote
and tesseract parsers will use these going forward
- `src/paperless/tests/parsers/test_remote_parser.py` — 42 pytest-style
tests using pytest-django `settings` and pytest-mock `mocker` fixtures
- `src/paperless/tests/parsers/conftest.py` — remote parser instance,
sample-file, and settings-helper fixtures
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Refactor: use fixture factory and usefixtures in remote parser tests
- `_make_azure_mock` helper promoted to `make_azure_mock` factory fixture
in conftest.py; tests call `make_azure_mock()` or
`make_azure_mock("custom text")` instead of a module-level function
- `azure_settings` and `no_engine_settings` applied via
`@pytest.mark.usefixtures` wherever their value is not referenced
inside the test body; `TestRemoteParserParseError` marked at the class
level since all three tests need the same setting
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Refactor: improve remote parser test fixture structure
- make_azure_mock moved from conftest.py back into test_remote_parser.py;
it is specific to that module and does not belong in shared fixtures
- azure_client fixture composes azure_settings + make_azure_mock + patch
in one step; tests no longer repeat the mocker.patch call or carry an
unused azure_settings parameter
- failing_azure_client fixture similarly composes azure_settings + patch
with a RuntimeError side effect; TestRemoteParserParseError now only
receives the mock it actually uses
- All @pytest.mark.parametrize calls use pytest.param with explicit ids
(pdf, png, jpeg, ...) for readable test output
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Refactor: wire RemoteDocumentParser into consumer and fix signals
- paperless_remote/signals.py: import from paperless.parsers.remote
(new location after git mv). supported_mime_types() is now a
classmethod that always returns the full set, so get_supported_mime_types()
in the signal layer explicitly checks RemoteEngineConfig validity and
returns {} when unconfigured — preserving the old behaviour where an
unconfigured remote parser does not register for any MIME types.
- documents/consumer.py: extend the _parser_cleanup() shim, parse()
dispatch, and get_thumbnail() dispatch to include RemoteDocumentParser
alongside TextDocumentParser. Both new-style parsers use __exit__
for cleanup and take (document_path, mime_type) without a file_name
argument.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Refactor: fix type errors in remote parser and signals
- remote.py: add `if TYPE_CHECKING: assert` guards before the Azure
client construction to narrow config.endpoint and config.api_key from
str|None to str. The narrowing is safe: engine_is_valid() guarantees
both are non-None when it returns True (api_key explicitly; endpoint
via `not (engine=="azureai" and endpoint is None)` for the only valid
engine). Asserts are wrapped in TYPE_CHECKING so they carry zero
runtime cost.
- signals.py: add full type annotations — return types, Any-typed
sender parameter, and explicit logging_group argument replacing *args.
Add `from __future__ import annotations` for consistent annotation style.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix: get_parser factory forwards logging_group, drops progress_callback
consumer.py calls parser_class(logging_group, progress_callback=...).
RemoteDocumentParser.__init__ accepts logging_group but not
progress_callback, so only the latter is dropped — matching the pattern
established by the TextDocumentParser signals shim.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix: text parser get_parser forwards logging_group, drops progress_callback
TextDocumentParser.__init__ accepts logging_group: object = None, same
as RemoteDocumentParser. The old shim incorrectly dropped it; fix to
forward it as a positional arg and only drop progress_callback.
Add type annotations and from __future__ import annotations for
consistency with the remote parser signals shim.

Add test_workflow_document_updated_does_not_overwrite_filename to
verify that run_workflows (DOCUMENT_UPDATED path) does not revert a
DB filename that was updated by a concurrent bulk_update_documents
task's update_filename_and_move_files call.
The test replicates the race window by:
- Updating the DB filename directly (simulating BUD-1 completing)
- Mocking refresh_from_db so the stale in-memory filename persists
- Asserting the DB filename is not clobbered after run_workflows

* Chore: move Tika parser and tests to paperless/
Move TikaDocumentParser and its tests to the canonical parser package
location, matching the pattern established for TextDocumentParser:
- src/paperless_tika/parsers.py → src/paperless/parsers/tika.py
- src/paperless_tika/tests/test_tika_parser.py → src/paperless/tests/parsers/test_tika_parser.py
- src/paperless_tika/tests/samples/ → src/paperless/tests/samples/tika/
Merge tika fixtures (tika_parser, sample_odt_file, sample_docx_file,
sample_doc_file, sample_broken_odt) into the shared parsers conftest.
Remove the now-empty src/paperless_tika/tests/conftest.py.
Content is unchanged — this commit is rename-only so git history is
preserved on the moved files.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Feature: Phase 3 — migrate TikaDocumentParser to ParserProtocol
Refactor TikaDocumentParser to satisfy ParserProtocol without subclassing
the legacy DocumentParser ABC:
- Add ClassVars: name, version, author, url
- Add supported_mime_types() classmethod (12 Office/ODF/RTF MIME types)
- Add score() classmethod — returns None when TIKA_ENABLED is False, 10 otherwise
- can_produce_archive = False (PDF is for display, not an OCR archive)
- requires_pdf_rendition = True (Office formats need PDF for browser display)
- __enter__/__exit__ via ExitStack: TikaClient opened once per parser
lifetime and shared across parse() and extract_metadata() calls
- extract_metadata() falls back to a short-lived TikaClient when called
outside a context manager (legacy view-layer metadata path)
- _convert_to_pdf() uses OutputTypeConfig() to honour the database-stored
ApplicationConfiguration before falling back to the env-var setting
- Rename convert_to_pdf → _convert_to_pdf (private helper)
Update paperless_tika/signals.py shim to import from the new module path
and drop the legacy logging_group/progress_callback kwargs.
Update documents/consumer.py to extend the existing TextDocumentParser
special cases to also cover TikaDocumentParser (parse/get_thumbnail
signatures, __exit__ cleanup).
Add TestTikaParserRegistryInterface (7 tests) covering score(), properties,
and ParserProtocol isinstance check. Update existing tests to use the new
accessor API (get_text, get_date, get_archive_path, _convert_to_pdf).
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix: update remaining imports and move live Tika tests after parser migration
- src/documents/tests/test_parsers.py: import TikaDocumentParser from
paperless.parsers.tika (old paperless_tika.parsers no longer exists)
- git mv paperless_tika/tests/test_live_tika.py →
paperless/tests/parsers/test_live_tika.py to co-locate all Tika tests
with the parser; update import and replace old attribute API
(tika_parser.text/.archive_path) with accessor methods
(get_text/get_archive_path)
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix: satisfy mypy and pyrefly for TikaDocumentParser
Use a TYPE_CHECKING-guarded assert to narrow self._tika_client from
TikaClient | None to TikaClient at the point of use in parse(). The
assert is visible to type checkers (TYPE_CHECKING=True) so both mypy
and pyrefly accept the subsequent attribute accesses without error;
at runtime TYPE_CHECKING is False so the assert never executes and no
ruff S101 suppression is required.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Fix: require context manager for TikaDocumentParser; clean up client lifecycle
- consumer.py: call __enter__ for new-style parsers so _tika_client and
_gotenberg_client are set before parse() is invoked
- views.py: use `with parser` (via nullcontext for old-style parsers) in
get_metadata so extract_metadata always runs inside a context manager
- tika.py: GotenbergClient added to ExitStack alongside TikaClient;
inline client creation removed from extract_metadata and _convert_to_pdf;
__exit__ uses ExitStack.close() instead of __exit__ pass-through

* Perf: stream manifest parsing with ijson in document_importer
Replace bulk json.load of the full manifest (which materializes the
entire JSON array into memory) with incremental ijson streaming.
Eliminates self.manifest entirely — records are never all in memory
at once.
- Add ijson>=3.2 dependency
- New module-level iter_manifest_records() generator
- load_manifest_files() collects paths only; no parsing at load time
- check_manifest_validity() streams without accumulating records
- decrypt_secret_fields() streams each manifest to a .decrypted.json
temp file record-by-record; temp files cleaned up after file copy
- _import_files_from_manifest() collects only document records (small
fraction of manifest) for the tqdm progress bar
Measured on 200 docs + 200 CustomFieldInstances:
- Streaming validation: peak memory 3081 KiB -> 333 KiB (89% reduction)
- Stream-decrypt to file: peak memory 3081 KiB -> 549 KiB (82% reduction)

* Perf: slim dict in _import_files_from_manifest, discard fields
When collecting document records for the file-copy step, extract only
the 4 keys the loop actually uses (pk + 3 exported filename keys) and
discard the full fields dict (content, checksum, tags, etc.).
Peak memory for the document-record list: 939 KiB -> 375 KiB (60% reduction).
Wall time unchanged.
* Refactor: migrate exporter/importer from tqdm to PaperlessCommand.track()
Replace direct tqdm usage in document_exporter and document_importer with
the PaperlessCommand base class and its track() method, which is backed by
Rich and handles --no-progress-bar automatically. Also removes the unused
ProgressBarMixin from mixins.py.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
* Refactor: add explicit supports_progress_bar and supports_multiprocessing to all PaperlessCommand subclasses
Each management command now explicitly declares both class attributes
rather than relying on defaults, making intent unambiguous at a glance.

* Perf: streaming manifest writer for document exporter (Phase 3)
Replaces the in-memory manifest dict accumulation with a
StreamingManifestWriter that writes records to manifest.json
incrementally, keeping only one batch resident in memory at a time.
Key changes:
- Add StreamingManifestWriter: writes to .tmp atomically, BLAKE2b
compare for --compare-json, discard() on exception
- Add _encrypt_record_inline(): per-record encryption replacing the
bulk encrypt_secret_fields() call; crypto setup moved before streaming
- Add _write_split_manifest(): extracted per-document manifest writing
- Refactor dump(): non-doc records streamed during transaction, documents
accumulated then written after filenames are assigned
- Upgrade check_and_write_json() from MD5 to BLAKE2b
- Remove encrypt_secret_fields() and unused itertools.chain import
- Add profiling marker to pyproject.toml
Measured improvement (200 docs + 200 CustomFieldInstances, same
dump() code path, only writer differs):
- Peak memory: ~50% reduction
- Memory delta: ~70% reduction
- Wall time and query count: unchanged

* Refactor: O(1) lookup table for CRYPT_FIELDS in per-record encryption
Add CRYPT_FIELDS_BY_MODEL to CryptMixin, derived from CRYPT_FIELDS at
class definition time. _encrypt_record_inline() now does a single dict
lookup instead of a linear scan per record, eliminating the loop and
break pattern.

Phase 1 -- Eliminate JSON round-trip in document exporter
Replace json.loads(serializers.serialize("json", qs)) with
serializers.serialize("python", qs) to skip the intermediate
JSON string allocation and parse step. Use DjangoJSONEncoder
in check_and_write_json() to handle native Python types
(datetime, Decimal, UUID) the Python serializer returns.
Phase 2 -- Batched QuerySet serialization in document exporter
Add serialize_queryset_batched() helper that uses QuerySet.iterator()
and itertools.islice to stream records in configurable chunks, bounding
peak memory during serialization to batch_size * avg_record_size rather
than loading the entire QuerySet at once.

This alters the retry/backoff logic in the init-wait-for-db script to be more
optimistic about database availability. During regular deployment and
operations of paperless-ngx, it's common to restart the application server with
the database instance already running, so we should optimize for this case.
Instead of unconditionally delaying 5 seconds between each connection attempt,
start with a minimum delay of 1 second and increase the delay linearly with
each attempt, maxing out at 10 seconds. This makes the retry count-based
failure mode less practical, so instead we just use a timeout-based approach.*
*NOTE: the original implementation would have an effective timeout of 25s. This
alters the behavior to 60s.
Additionally, this removes an unnecessary 5s delay that was injected in the
postgres case. The script uses a more comprehensive connection check for
postgres than it does mariadb, so if anything this 5s delay after getting an
"ok" response from the DB was extra unnecessary in the postgres case.
* chore(devcontainer): drop read-only host .gitconfig bind mount
The bind mount prevented adjusting git config inside the dev container, and VS Code Dev Containers already copies the host .gitconfig automatically, making the mount unnecessary. This restores ability to manage git settings within the container.
* chore(gitignore): ignore .pnpm-store folder for pnpm package management
Add .pnpm-store/ to .gitignore to prevent local pnpm package store from being tracked by git when using the devcontainer.
* docs(development): clarify VS Code devcontainer setup steps for Windows
Add instructions, how to overcome some issues caused by using Windows as host system.
This helps prevent excessive processing times on very large documents
by limiting the text analyzed during date parsing, tag prediction,
and correspondent matching.
If the document exceeds 1.2M chars, crop to 1M char.

## Committing from the Host Machine
The DevContainer automatically installs Git pre-commit hooks during setup. However, these hooks are configured for use inside the container.
If you want to commit changes from your host machine (outside the DevContainer), you need to set up prek on your host. This installs it as a standalone tool.
```bash
uv tool install prek && prek install
```
After this, you can commit either from inside the DevContainer or from your host machine.

The Paperless-ngx team and community take security issues seriously. We appreciate good-faith reports and will make every effort to review legitimate findings responsibly.
To report a security issue, please use the GitHub Security Advisory ["Report a Vulnerability"](https://github.com/paperless-ngx/paperless-ngx/security/advisories/new) tab.
The team will send a response indicating the next steps in handling your report. After the initial reply to your report, the security team will keep you informed of the progress towards a fix and full announcement, and may ask for additional information or guidance.
After the initial reply to your report, the team may ask for additional information, reproduction steps, affected versions, configuration details, or proof-of-concept material needed to verify the issue.
## What makes a helpful report
Please include as much of the following as possible:
- A clear description of the issue and why it is a security vulnerability.
- Affected Paperless-ngx version(s).
- Required configuration, permissions, or preconditions.
- Step-by-step reproduction instructions.
- A realistic impact statement.
- Logs, screenshots, requests, or a proof of concept where appropriate.
- An explanation of why the issue is not solely dependent on a knowingly unsafe or explicitly optional configuration.
Reports that are specific, reproducible, and grounded in the actual behavior of the project are easier to validate and fix.
## AI-assisted submissions
AI tools can be useful for security research, but they can also produce plausible-sounding reports that do not reflect actual vulnerabilities in Paperless-ngx.
If you use AI tools to help draft or investigate a report, please disclose this and verify the result yourself before submission. Make sure the report:
- identifies a real code path in this project
- includes a real reproduction, not just a theoretical concern
- demonstrates realistic impact
- accounts for existing permission checks, configuration requirements, and trust boundaries
- is about Paperless-ngx itself, rather than a hypothetical deployment, downstream customization, third-party app, scanner output, reverse proxy behavior, or external service unless you can show a direct product vulnerability
Submitting unverified AI-generated claims creates unnecessary review work and slows down handling of legitimate reports.
<!-- Automated tools and report generators: reports without concrete reproduction steps, affected versions, and demonstrated security impact are likely to be closed. -->
## Common reasons reports are closed
We may close reports that are:
- missing reproduction details
- best-practice recommendations presented as vulnerabilities
- theoretical claims without a demonstrated exploit path or realistic impact
- dependent on administrator-controlled, explicitly optional, or knowingly unsafe configuration
- based on privileges that already make the reported behavior expected
- limited to unsupported versions
- about third-party software, integrations, deployment choices, or client applications without a demonstrable Paperless-ngx vulnerability
- duplicates
- UI bugs, feature requests, scanner quirks, or general usability issues submitted through the security channel
## Common non-vulnerability categories
The following are not generally considered vulnerabilities unless accompanied by a concrete, reproducible impact in Paperless-ngx:
- large uploads or resource usage that do not bypass documented limits or privileges
- IDOR / access control claims regarding the ability to attach an un-viewable object to a document. This is expected behavior.
- claims based solely on the presence of a library, framework feature or code pattern without a working exploit
- reports that rely on admin-level access, workflow-editing privileges, shell access, or other high-trust roles unless they demonstrate an unintended privilege boundary bypass
- optional webhook, mail, AI, OCR, or integration behavior described without a product-level vulnerability
- missing limits or hardening settings presented without concrete impact
- generic AI or static-analysis output that is not confirmed against the current codebase and a real deployment scenario
## Transparency
We may publish anonymized examples or categories of rejected reports to clarify our review standards, reduce duplicate low-quality submissions, and help good-faith reporters send actionable findings.
A mistaken report made in good faith is not misconduct. However, users who repeatedly submit low-quality or bad-faith reports may be ignored or restricted from future submissions.
## Scope and expectations
Please use the security reporting channel only for security vulnerabilities in Paperless-ngx.
Please do not use the security advisory system for:
- support questions
- general bug reports
- feature requests
- browser compatibility issues
- issues in third-party mobile apps, reverse proxies, or deployment tooling unless you can demonstrate a Paperless-ngx vulnerability
The team will review reports as time permits, but submission does not guarantee that a report is valid, in scope, or will result in a fix. Reports that do not describe a reproducible product-level issue may be closed without extended back-and-forth.

@@ -69,33 +69,33 @@ Paperless tries to hide much of the involved complexity with this
approach. However, there are a couple caveats you need to keep in mind
when using this feature:
- Changes to your documents are not immediately reflected by the
matching algorithm. The neural network needs to be _trained_ on your
documents after changes. Paperless periodically (default: once each
hour) checks for changes and does this automatically for you.
- The Auto matching algorithm only takes documents into account which
are NOT placed in your inbox (i.e. have any inbox tags assigned to
them). This ensures that the neural network only learns from
documents which you have correctly tagged before.
- The matching algorithm can only work if there is a correlation
between the tag, correspondent, document type, or storage path and
the document itself. Your bank statements usually contain your bank
account number and the name of the bank, so this works reasonably
well, However, tags such as "TODO" cannot be automatically
assigned.
- The matching algorithm needs a reasonable number of documents to
identify when to assign tags, correspondents, storage paths, and
types. If one out of a thousand documents has the correspondent
"Very obscure web shop I bought something five years ago", it will
probably not assign this correspondent automatically if you buy
something from them again. The more documents, the better.
- Paperless also needs a reasonable amount of negative examples to
decide when not to assign a certain tag, correspondent, document
type, or storage path. This will usually be the case as you start
filling up paperless with documents. Example: If all your documents
are either from "Webshop" or "Bank", paperless will assign one
of these correspondents to ANY new document, if both are set to
automatic matching.

well, However, tags such as "TODO" cannot be automatically
assigned.
- The matching algorithm needs a reasonable number of documents to
identify when to assign tags, correspondents, storage paths, and
types. If one out of a thousand documents has the correspondent
"Very obscure web shop I bought something five years ago", it will
probably not assign this correspondent automatically if you buy
something from them again. The more documents, the better.
- Paperless also needs a reasonable amount of negative examples to
decide when not to assign a certain tag, correspondent, document
type, or storage path. This will usually be the case as you start
filling up paperless with documents. Example: If all your documents
are either from "Webshop" or "Bank", paperless will assign one
of these correspondents to ANY new document, if both are set to
automatic matching.

Paperless-ngx uses a plugin system for date parsing, allowing you to extend or replace the default date parsing behavior. Plugins are discovered using [Python entry points](https://setuptools.pypa.io/en/latest/userguide/entry_point.html).
#### Creating a Date Parser Plugin
To create a custom date parser plugin, you need to:
1. Create a class that inherits from `DateParserPluginBase`
2. Implement the required abstract method
3. Register your plugin via an entry point
##### 1. Implementing the Parser Class
Your parser must extend `documents.plugins.date_parsing.DateParserPluginBase` and implement the `parse` method:
```python
from collections.abc import Iterator
import datetime
from documents.plugins.date_parsing import DateParserPluginBase
Parse dates from the document's filename and content.
Args:
filename: The original filename of the document
content: The extracted text content of the document
Yields:
datetime.datetime: Valid datetime objects found in the document
"""
# Your parsing logic here
# Use self.config to access configuration settings
# Example: parse dates from filename first
if self.config.filename_date_order:
# Your filename parsing logic
yield some_datetime
# Then parse dates from content
# Your content parsing logic
yield another_datetime
```
##### 2. Configuration and Helper Methods
Your parser instance is initialized with a `DateParserConfig` object accessible via `self.config`. This provides:
- `languages: list[str]` - List of language codes for date parsing
- `timezone_str: str` - Timezone string for date localization
- `ignore_dates: set[datetime.date]` - Dates that should be filtered out
- `reference_time: datetime.datetime` - Current time for filtering future dates
- `filename_date_order: str | None` - Date order preference for filenames (e.g., "DMY", "MDY")
- `content_date_order: str` - Date order preference for content
The base class provides two helper methods you can use:
```python
def _parse_string(
self,
date_string: str,
date_order: str,
) -> datetime.datetime | None:
"""
Parse a single date string using dateparser with configured settings.
"""
def _filter_date(
self,
date: datetime.datetime | None,
) -> datetime.datetime | None:
"""
Validate a parsed datetime against configured rules.
Filters out dates before 1900, future dates, and ignored dates.
"""
```
##### 3. Resource Management (Optional)
If your plugin needs to acquire or release resources (database connections, API clients, etc.), override the context manager methods. Paperless-ngx will always use plugins as context managers, ensuring resources can be released even in the event of errors.
##### 4. Registering Your Plugin
Register your plugin using a setuptools entry point in your package's `pyproject.toml`:
The entry point name (e.g., `"my_parser"`) is used for sorting when multiple plugins are found. Paperless-ngx will use the first plugin alphabetically by name if multiple plugins are discovered.
#### Plugin Discovery
Paperless-ngx automatically discovers and loads date parser plugins at runtime. The discovery process:
1. Queries the `paperless_ngx.date_parsers` entry point group
2. Validates that each plugin is a subclass of `DateParserPluginBase`
3. Sorts valid plugins alphabetically by entry point name
4. Uses the first valid plugin, or falls back to the default `RegexDateParserPlugin` if none are found
If multiple plugins are installed, a warning is logged indicating which plugin was selected.
#### Example: Simple Date Parser
Here's a minimal example that only looks for ISO 8601 dates:
```python
import datetime
import re

Upgrading to Paperless-ngx v3 can only be performed from version 2.20.15. If you are running an older version, please upgrade to v2.20.15 before proceeding with the v3 upgrade.
## Secret Key is Now Required
The `PAPERLESS_SECRET_KEY` environment variable is now required. This is a critical security setting used for cryptographic signing and should be set to a long, random value.
### Action Required
If you are upgrading an existing installation, you must now set `PAPERLESS_SECRET_KEY` explicitly.
If your installation was relying on the previous built-in default key, you have two options:
- Set `PAPERLESS_SECRET_KEY` to that previous value to preserve existing sessions and tokens.
- Set `PAPERLESS_SECRET_KEY` to a new random value to improve security, understanding that this will invalidate existing sessions and other signed tokens.
For new installations, or if you choose to rotate the key, you may generate a new secret key with:
| `CONSUMER_POLLING` | [`CONSUMER_POLLING_INTERVAL`](configuration.md#PAPERLESS_CONSUMER_POLLING_INTERVAL) | Renamed for clarity |
| `CONSUMER_INOTIFY_DELAY` | [`CONSUMER_STABILITY_DELAY`](configuration.md#PAPERLESS_CONSUMER_STABILITY_DELAY) | Unified for all modes |
| `CONSUMER_POLLING_DELAY` | _Removed_ | Use `CONSUMER_STABILITY_DELAY` |
| `CONSUMER_POLLING_RETRY_COUNT` | _Removed_ | Automatic with stability tracking |
| `CONSUMER_IGNORE_PATTERNS` | [`CONSUMER_IGNORE_PATTERNS`](configuration.md#PAPERLESS_CONSUMER_IGNORE_PATTERNS) | **Now regex, not fnmatch**; user patterns are added to (not replacing) default ones |
| _New_ | [`CONSUMER_IGNORE_DIRS`](configuration.md#PAPERLESS_CONSUMER_IGNORE_DIRS) | Additional directories to ignore; user entries are added to (not replacing) defaults |
## Duplicate Handling Changes
Paperless-ngx v3 no longer rejects duplicate documents by default. Instead, it now allows duplicates but adds a way to identify them via the UI. To (re-)enable duplicate rejection, set `PAPERLESS_CONSUMER_DELETE_DUPLICATES=true` in your environment.
## Encryption Support
Document and thumbnail encryption is no longer supported. This was previously deprecated in [paperless-ng 0.9.3](https://github.com/paperless-ngx/paperless-ngx/blob/dev/docs/changelog.md#paperless-ng-093)
Users must decrypt their document using the `decrypt_documents` command before upgrading.
## Barcode Scanner Changes
Support for [pyzbar](https://github.com/NaturalHistoryMuseum/pyzbar) has been removed. The underlying libzbar library has
seen no updates in 16 years and is largely unmaintained, and the pyzbar Python wrapper last saw a release in March 2022. In
practice, pyzbar struggled with barcode detection reliability, particularly on skewed, low-contrast, or partially
obscured barcodes. [zxing-cpp](https://github.com/zxing-cpp/zxing-cpp) is actively maintained, significantly more
reliable at finding barcodes, and now ships pre-built wheels for both x86_64 and arm64, removing the need to build the library.
The `CONSUMER_BARCODE_SCANNER` setting has been removed. zxing-cpp is now the only backend.
The settings that control OCR behaviour and archive file generation have been redesigned. The old settings that coupled these two concerns together are **removed** — old values are not silently honoured; a startup warning is logged if any removed variable is still set in your environment.
Previously, `OCR_MODE` conflated two independent concerns: whether to run OCR and whether to produce an archive. `skip` meant "skip OCR if text exists, but always produce an archive". `skip_noarchive` meant "skip OCR if text exists, and also skip the archive". This made it impossible to, for example, disable OCR entirely while still producing archives.
If you changed OCR settings via the admin UI (ApplicationConfiguration), the database values are **migrated automatically** during the upgrade. `mode` values (`skip` / `skip_noarchive`) are mapped to their new equivalents and `skip_archive_file` values are converted to the new `archive_file_generation` field. After upgrading, review the OCR settings in the admin UI to confirm the migrated values match your intent.
### Action Required
Remove any `PAPERLESS_OCR_SKIP_ARCHIVE_FILE` variable from your environment. If you relied on `OCR_MODE=skip` or `OCR_MODE=skip_noarchive`, update accordingly:
```bash
# v2: skip OCR when text present, always archive
PAPERLESS_OCR_MODE=skip
# v3: equivalent (auto is the new default)
# No change needed — auto is the default
# v2: skip OCR when text present, skip archive too
PAPERLESS_OCR_MODE=skip_noarchive
# v3: equivalent
PAPERLESS_OCR_MODE=auto
PAPERLESS_ARCHIVE_FILE_GENERATION=never
# v2: always skip archive
PAPERLESS_OCR_SKIP_ARCHIVE_FILE=always
# v3: equivalent
PAPERLESS_ARCHIVE_FILE_GENERATION=never
# v2: skip archive only for born-digital docs
PAPERLESS_OCR_SKIP_ARCHIVE_FILE=with_text
# v3: equivalent (auto is the new default)
PAPERLESS_ARCHIVE_FILE_GENERATION=auto
```
### Remote OCR parser
If you use the **remote OCR parser** (Azure AI), note that it always produces a
searchable PDF and stores it as the archive copy. `ARCHIVE_FILE_GENERATION=never`
has no effect for documents handled by the remote parser — the archive is produced
unconditionally by the remote engine.
# Search Index (Whoosh -> Tantivy)
The full-text search backend has been replaced with [Tantivy](https://github.com/quickwit-oss/tantivy).
The index format is incompatible with Whoosh, so **the search index is automatically rebuilt from
scratch on first startup after upgrading**. No manual action is required for the rebuild itself.
### Note and custom field search syntax
The old Whoosh index exposed `note` and `custom_field` as flat text fields that were included in
unqualified searches (e.g. just typing `invoice` would match note content). With Tantivy these are
now structured JSON fields accessed via dotted paths:
The task tracking system has been redesigned in this release. All existing task history records are dropped from the database during the upgrade. Previously completed, failed, or acknowledged tasks will no longer appear in the task list after upgrading.
No user action is required.
## Consume Script Positional Arguments Removed
Pre- and post-consumption scripts no longer receive positional arguments. All information is
now passed exclusively via environment variables, which have been available since earlier versions.
### Pre-consumption script
Previously, the original file path was passed as `$1`. It is now only available as
`DOCUMENT_SOURCE_PATH`.
**Before:**
```bash
#!/usr/bin/env bash
# $1 was the original file path
process_document "$1"
```
**After:**
```bash
#!/usr/bin/env bash
process_document "${DOCUMENT_SOURCE_PATH}"
```
### Post-consumption script
Previously, document metadata was passed as positional arguments `$1` through `$8`:
| Argument | Environment Variable Equivalent |
| -------- | ------------------------------- |
| `$1` | `DOCUMENT_ID` |
| `$2` | `DOCUMENT_FILE_NAME` |
| `$3` | `DOCUMENT_SOURCE_PATH` |
| `$4` | `DOCUMENT_THUMBNAIL_PATH` |
| `$5` | `DOCUMENT_DOWNLOAD_URL` |
| `$6` | `DOCUMENT_THUMBNAIL_URL` |
| `$7` | `DOCUMENT_CORRESPONDENT` |
| `$8` | `DOCUMENT_TAGS` |
**Before:**
```bash
#!/usr/bin/env bash
DOCUMENT_ID=$1
CORRESPONDENT=$7
TAGS=$8
```
**After:**
```bash
#!/usr/bin/env bash
# Use environment variables directly
echo"Document ${DOCUMENT_ID} from ${DOCUMENT_CORRESPONDENT} tagged: ${DOCUMENT_TAGS}"
```
### Action Required
Update any pre- or post-consumption scripts that read `$1`, `$2`, etc. to use the
corresponding environment variables instead. Environment variables have been the preferred
option since v1.8.0.

# 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.
- 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)
| 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.
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.
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).
- https://github.com/qdrant/qdrant-client/issues/765, https://github.com/milvus-io/milvus-lite/issues/264 (multi-process locks; the milvus one is v2-era, superseded by the v3 pure-Python rewrite)

**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.
(`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:
return []
current = self.stored_schema_version()
return [m for m in MIGRATIONS if m.version > current]
def requires_reembed_migration(self) -> bool:
"""True when any pending migration requires a full re-embedding."""
return any(m.requires_reembed for m in self.pending_migrations())
Inside the `with write_store(embed_model_name=model_name) as store:` block in `update_llm_index`, insert the migration check immediately before the `if rebuild or not store.table_exists():` line:
```python
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
```
The relevant section of `update_llm_index` should now look like:
```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.")
## 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)"}),

**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
- [ ]**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"`:
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.
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**
Expected: all green. In particular, `TestSchemaVersioning::test_stored_schema_version_persists_after_reopen` and the `TestMigrationRegistry` tests should still pass — they use `CURRENT_SCHEMA_VERSION` as the baseline.
---
### Task 7: Integration — `update_llm_index` rebuilds when schema version is stale
Expected: `FAILED` — schema version stays at 1 because migration v2 isn't registered yet.
_(If it passes already because `update_llm_index` detects a different condition, verify the assertion is actually exercising the migration path and not the model-name path.)_
- [ ] **Step 3: Run the test again now that migration v2 is registered (Task 6)**
**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.
