* Fix: authorize document versions by their root and speed up permission id sets
permitted_document_ids judged a version by its own owner and grants, so a
version whose owner had drifted from its root's was visible to the wrong
people and hidden from the right ones. Callers patched this individually by
mapping each document to its root first. The query itself was also slow on
MariaDB: the guardian grants were a UNION cast to integers and tested with
IN inside an OR with the owner checks, which MariaDB cannot materialize, so it
re-scans the user's grants for every document. At 20k documents that took
seconds for a user with a couple of hundred grants.
permitted_object_ids now casts the row key to a string, as guardian stores
object_pk, and tests it against a single uncorrelated UNION ALL of the user's
and groups' grants. No integer cast is needed and the user's groups are
matched with an IN subquery rather than a join through the membership table.
Postgres and SQLite build the grant set once, and MariaDB probes guardian's
unique indexes per row, which is cheap. A correlated EXISTS per grant also
fixed MariaDB but was up to 3x slower than before on Postgres and SQLite.
permitted_object_ids also takes an optional parent_field naming a
self-referencing foreign key whose target authorizes the row, and
permitted_document_ids passes root_document, so a version is visible exactly
when its root is. The helper that mapped documents to their roots at the call
sites is no longer needed, so the email, selection data, share link bundle,
trash, bulk download and bulk edit checks use the id set directly.

SetPermissionsSerializer was a bare DictField, and the legacy bulk_edit
set_permissions parameter bypassed even that by hand-calling
validate_set_permissions() on an unchecked dict. A bool or a non-list in
place of users/groups crashed with a raw TypeError instead of a 400.
It is now a nested serializer (view/change, each with users/groups as
lists of integers), used for owned-object create/update, the legacy
bulk_edit set_permissions parameter, and bulk_edit_objects permissions.
Unknown action keys are rejected: previously a typo like "veiw" was
silently dropped, leaving an empty permission set that could clear
existing grants. An explicit set_permissions null (an owner-only change)
remains a no-op, and an empty bulk_edit_objects permissions dict is still
rejected.
* Perf: batch guardian permission assignment in bulk-edit
bulk_edit.set_permissions and BulkEditObjectPermissionsView both
looped documents/objects and called set_permissions_for_object per
object, which itself calls guardian's assign_perm/remove_perm once
per (object, user) pair -- ~10-20+ queries per object, scaling with
selection size.
Added set_permissions_for_objects, a bulk equivalent that resolves
existing permission holders once across the whole batch (not once per
object) and applies changes with a small, batch-size-independent
number of queries per action instead of one per (object, user) pair.
* Perf: avoid unnecessary full-row fetches in batch permission assignment
set_permissions_for_objects now takes a model + pks instead of instances,
and identity filtering resolves straight to ids, so bulk-editing
permissions no longer materializes full Document/User/Group rows just to
read their pk/id. Row construction for bulk_create is also chunked to
bound peak memory for very large "apply to all" operations.
* Fix: use .distinct() for existing-grant lookup, drop flaky query-count invariant tests
.distinct() lets the database dedupe identity ids server-side instead of
transferring one row per (object, grantee) match and deduping in Python --
was the dominant cost on a large selection with existing grants.
Also replaced the two query-count-equality tests (bulk_edit and the
bulk_edit_objects API path) with plain functional-correctness checks at
both batch sizes. Hopefully stops that flake.
* Mark empty-pks early-return in set_permissions_for_objects as no-cover
Defensive guard for an edge case (all requested pks already gone/invalid)
rather than a path normal usage exercises; matches the existing
pragma: no cover convention elsewhere in this file.
* Perf: drop speculative row-chunking in bulk permission assignment, keep the query-batching fix
* Resolve every permission action before applying any of them
This fixes the existing issue and resolves the Copilot comment
* Assert permission assignment does not scale with selection size
The two batching tests only checked that permissions came out correct at
5 and 50 objects, so reverting to the old per-object loop would still
have passed. Check sizes as well to prevent that
AI Suggestions previously invented near-duplicate metadata because the classification
prompt had no knowledge of the installation's own taxonomy. This surfaces
a small, ranked, permission-filtered set of existing tags/document
types/correspondents/storage paths - drawn from the document's RAG
neighbors plus its own already-assigned metadata - so the model prefers
reusing what already exists.
The LLM response schema now returns existing_ids (IDs of reused
candidates) separately from new_names (genuinely new suggestions).
Only new_names goes through localization and fuzzy name-matching;
existing_ids is resolved deterministically and never touched by the
localization pass, so exact matches can no longer be silently
corrupted by translation.
* feat: add unified PermittedObjectsFilter backed by permitted_object_ids
* refactor: migrate all ViewSets to unified PermittedObjectsFilter
Replace the deprecated ObjectOwnedOrGrantedPermissionsFilter,
DocumentPermissionsFilter, and ObjectOwnedPermissionsFilter aliases
with PermittedObjectsFilter directly across documents/views.py (8
sites, including TrashView's include_granted=False subclass) and
paperless_mail/views.py (3 sites), then delete the now-unreferenced
alias classes from documents/filters.py.

* docs: document legacy status of get_objects_for_user_owner_aware/has_perms_owner_aware
Stage 4's PermittedObjectsFilter/permitted_object_ids() covers the
queryset-filtering use case, but both functions still have production
callers outside this plan's scope (documents/views.py,
documents/serialisers.py, documents/signals/handlers.py,
paperless_ai/matching.py, paperless_ai/ai_classifier.py). Per Task 20
Step 2, they are kept in place rather than partially deleted, with
docstrings updated to note their legacy status and remaining callers.

* Fix: address final review findings for permission-filter unification
- Add a permanent regression test pinning TrashView's include_granted=False
wiring: an explicit view_document grant on a trashed document must not
leak it into /api/trash/ for a non-owner, non-superuser requester.
- Drop the now-dead direct dependency djangorestframework-guardian; the
last rest_framework_guardian import was removed by this branch's
migration onto PermittedObjectsFilter. django-guardian is untouched.
- Replace the hand-maintained, already-stale caller lists in
get_objects_for_user_owner_aware/has_perms_owner_aware docstrings with a
pointer to grep for remaining callers instead.
- In PermittedObjectsFilter.filter_queryset, compute `model` only on the
include_granted=True path that actually uses it.

* perf: check bulk-edit-objects apply_to_all permissions via DB-side exclude/exists
Materialized the full permitted_object_ids() set into a Python set() just
to check membership for the request's objs queryset -- the same pattern
already fixed at four other sites for Document. This one is used by
apply_to_all, where objs can be an unbounded filtered selection (e.g. all
tags matching a filter) rather than a small request-supplied ID list,
making the wasted materialization worse here than at the sites already
fixed.

* feat: generalize permitted_document_ids into permitted_object_ids for any model
Implements Task 14 of the permission-filtering consolidation plan:
- Add generic permitted_object_ids(user, model, perm, include_deleted=False)
- Refactor permitted_document_ids to delegate to permitted_object_ids
- Add comprehensive tests for Tag/Correspondent/DocumentType/StoragePath
- Preserve exact public behavior of permitted_document_ids (100% regression-free)
All 38 tests pass (18 existing + 20 new). The include_deleted parameter
correctly handles soft-delete patterns (effective only for Document).

* refactor: add type hints to permitted_object_ids and permitted_document_ids
Add missing type annotations to match the established conventions in this file
(see get_objects_for_user_owner_aware). Also added Model import from django.db.models.
- permitted_object_ids: user: User | None, model: type[Model], return -> QuerySet[int]
- permitted_document_ids: user: User | None, return -> QuerySet[int]
All 38 permission filtering security tests pass; this is a type-annotation-only change.

* refactor: remove redundant deleted_at filter in permitted_object_ids

* feat: add perm param to permitted_document_ids for change/delete checks
Widens permitted_document_ids(user, *, include_deleted=False) to
permitted_document_ids(user, *, perm="view_document", include_deleted=False)
so Stage 2 callers can check change_document/delete_document permissions
instead of the hardcoded view_document codename. Default is unchanged for
every existing call site.

* test: strengthen delete-permission include_deleted test to discriminate from other grants
test_delete_permission_with_include_deleted_for_trash_restore only checked
an owner and a fully-ungranted stranger, so it never proved perm=
actually discriminates delete_document from other permission grants. Add
a view_only user with view_document (but not delete_document) granted on
the same doc and assert they remain excluded, mirroring the pattern in
test_change_document_permission_is_distinct_from_view.
* fix: normalize qualified permission strings in permitted_document_ids
Guardian's UserObjectPermission/GroupObjectPermission always store a bare
codename, but has_perm()-style callers commonly pass the qualified
"app_label.codename" form. Passing that qualified form here previously
matched zero rows, silently under-permitting. content_type already
disambiguates the codename, so just strip any prefix instead.

* feat: add include_deleted param to permitted_document_ids
Widens permitted_document_ids to accept an include_deleted keyword-only
flag (default False, preserving current behavior) so later call sites
that need visibility into soft-deleted documents (e.g. trash restore)
can reuse this permission check instead of duplicating it.
* refactor: remove redundant deleted_at filter in permitted_document_ids
Document.objects already applies filter(deleted_at__isnull=True) internally
via SoftDeleteManager.get_queryset(), so the conditional filter was redundant.
Simplify to just use manager.all() in both branches — manager selection alone
ensures correct behavior (Document.objects excludes deleted, Document.global_objects
includes all).

The permission filter OR'd three querysets together on top of a
queryset that could already carry two independent tags__id__all
joins, letting a document that matched more than one branch (e.g.
unowned + group-permissioned) come back twice. Replaced it with a
single id__in filter against the existing permitted_document_ids
helper, which is join-free and can't hit this.
* Fix: selection_data re-derives the filtered document set 5 times over
_get_selection_data_for_queryset() (powers ?include_selection_data=true on
the document list and search endpoints) computed document_count for
Correspondent/DocumentType/StoragePath/Tag/CustomField by embedding the
caller's full filtered queryset -- filters plus the permission check -- as
a subquery inside 5 separate Count(filter=Q(documents__in=queryset), ...)
calls. Each one re-evaluates that whole queryset from scratch.
Resolve the document ids once into a concrete list and reuse it across all
five annotations instead. For Tag/CustomField specifically (M2M via a
through-model table), also route through annotate_document_count_by_ids()
-- extracted from the tag/custom-field document_count fix (#13203) -- to
avoid the same Count(filter=Q(id__in=...), distinct=True)-on-an-M2M-relation
anti-pattern diagnosed there.
On a 400k-document/1,000-tag corpus, the correspondents portion alone
previously didn't finish within several minutes (killed twice while
investigating, including one run that left a zombie query still consuming
a CPU 30+ minutes later). All five queries together now complete in
~30-35s. Root-caused from a real report (paperless-ngx#13201) via a
different, already-fixed query (#13205) -- this one hasn't been reported
in the wild yet, found by auditing the same call path.
Depends on #13203 for annotate_document_count_by_ids().

* Address review feedback: drop unnecessary ordering before collecting ids
queryset passed into _get_selection_data_for_queryset() carries the
default/user-specified ordering, which is irrelevant once we're only
collecting a flat id list. Clearing it removes a pointless sort.
No measurable change in benchmarking at 400k documents -- the id-list
materialization/IN-clause cost still dominates -- but it's a free,
strictly-correct cleanup, not just noise-neutral in the other direction.

* Fix (beta): tag/custom-field document_count scales badly with tag count
TagViewSet and CustomFieldViewSet's document_count annotation used a
per-row correlated subquery (annotate_document_count_for_related_queryset),
executed once per tag/custom-field row. Fine at a few dozen rows, but at
~1,000 tags it degrades to a full per-tag GroupAggregate over the tags M2M
table -- 6s+ in production reports, confirmed via EXPLAIN (loops=1000).
Replaced with a single, independent GROUP BY over the through table
(permission filter expressed as a plain WHERE, not an aggregate FILTER),
then injected via Case/When. Also tried a more "obvious" fix -- a plain
Count(filter=Q(id__in=permitted_ids), distinct=True) directly on the M2M
relation -- but that's worse: Postgres fails to plan the id__in check as a
semi-join once a large M2M bridge table is involved, and instead re-checks
subquery membership once per joined row.
Benchmarked against a synthetic corpus (400k documents, 1,000 tags @ ~5/doc,
matching real-world reports in discussion #13161): tag list wall-clock drops
from ~180s to ~8s for a permission-restricted user, ~21s to ~8s for a
superuser. No measurable change at typical home-instance scale (tens of
tags).

* Address review feedback: restore validation, scope aggregation to queryset
- Restore the document_count_source_field validation helper dropped during
the refactor -- misconfiguring a viewset (document_count_through set
without document_count_source_field) now fails fast with a clear error
again instead of an obscure runtime failure.
- Restrict annotate_document_count_for_related_queryset()'s through-table
aggregation to rows whose related_object_field is one of the annotated
queryset's pks. No-op for the main tag-list call site (queryset is all
tags), but avoids unnecessary work for narrower callers like the tag
descendants branch in TagViewSet.list().
