 ## [Unreleased]
 
+### Added
+
+- **Return-type annotations across `config/graphql/` resolvers and mutations** (Issue #1332, follow-up to #1331): The largest, least-typed subtree in the backend (459 function definitions, ~4.4% return-annotation coverage at baseline) is now at 100% return-annotation coverage. Touched files include every `*_mutations.py`, every `*_queries.py`, every `*_types.py`, plus `filters.py`, `base.py`, `base_types.py`, `security.py`, `optimized_file_resolvers.py`, `permissioning/permission_annotator/{middleware,mixins,utils}.py`, and the small utility modules. No behavioral changes — annotations only.
+  - **`mutate(...)` on `graphene.Mutation` subclasses**: typed as forward references to the enclosing class (`-> "ClassName"`). Discovered and fixed the latent bug in `config/graphql/analysis_mutations.py:179` (`DeleteAnalysisMutation.mutate`) where the success path had no `return` statement; annotation is `-> "DeleteAnalysisMutation | None"` and an explicit `return None` was added to preserve the original implicit-None behavior on success.
+  - **`resolve_*` methods**: typed as `-> Any` by default, refined where the GraphQL field type makes the runtime return obvious (e.g. `resolve_in_use -> bool`, `resolve_datacell_count -> int`).
+  - **`AnnotatePermissionsForReadMixin`** (`config/graphql/permissioning/permission_annotator/mixins.py`): per the issue's specific guidance, `resolve_my_permissions -> list[str]`, `resolve_is_published -> bool`, `resolve_object_shared_with -> list[dict[str, Any]]`. The pre-existing wrong annotation `list[PermissionTypes]` (an Enum, while the implementation returns plain strings) was corrected to `list[str]`. The now-unused `PermissionTypes` import was removed.
+  - **Filter / queryset helpers** (`filter_by_*`, `text_search_method`, `get_node`, `get_queryset`, `_get_*`, etc.) typed as `-> Any` to keep the change conservative; tightening to `QuerySet[Model]` is a follow-up.
+  - **`config/graphql/permissioning/permission_annotator/utils.py`** had a broken import (`config.graphql.permission_annotator.middleware` instead of `config.graphql.permissioning.permission_annotator.middleware`) — fixed in passing.
+  - **`config/graphql/conversation_types.py`**: replaced `base64.binascii.Error` with a direct `binascii.Error` import (pre-existing — `base64` re-exports `binascii` at runtime but `mypy` doesn't see the re-export).
+  - **Var-annotated additions**: `id_to_children: dict[Any, list[Any]]` in `base_types.py`, `read_only_fields: list[str]` in `serializers.py`, `this_model_permission_id_map: dict[int, str]` etc. in middleware.
+  - **Five modules graduated from the mypy baseline** (`mypy.ini` → no longer `ignore_errors = True`): `config.graphql.base_types`, `config.graphql.conversation_types`, `config.graphql.permissioning.permission_annotator.middleware`, `config.graphql.permissioning.permission_annotator.utils`, `config.graphql.serializers`. Their entries in `docs/typing/mypy_baseline.txt` (11 lines) were also pruned. Future PRs can graduate the remaining baselined files as the structural issues they expose (custom `visible_to_user` manager method not seen by `django-stubs`, `set_permissions_for_obj_to_user` signature mismatch, mixin `_meta` access) are addressed.
+  - **Tooling**: zero new `# type: ignore` markers; black & isort applied; `flake8 config/graphql/` clean. `mypy --config-file mypy.ini opencontractserver config` passes with the updated baseline.
+- **Mypy: graduated `opencontractserver/users/tasks.py` out of the baseline** (Issue #1333 follow-up): `tasks.py` was the last `opencontractserver.users` module still suppressed in `mypy.ini`. PR #1370 left it untyped because the file is only loaded when `settings.USE_AUTH0=True`, so it never failed at runtime under the test settings; the typing gap kept the package short of the issue's "all four packages at ≥80% return-annotation coverage" Done-When criterion. Added return + parameter annotations to all five Auth0 sync tasks (`get_new_auth0_token`, `apply_data_to_user`, `sync_remote_user`, `ensure_valid_auth0_token`, `get_user_details_async`), introduced a module-level docstring documenting the `USE_AUTH0` gating, and removed the `[mypy-opencontractserver.users.tasks] ignore_errors = True` section. Local `data` rebound from request body (`dict[str, str]`) to response payload (`dict[str, Any]`) was split into two distinctly-named variables (`request_data` / `payload`) so the types are unambiguous; behavior is unchanged. No callers needed updating — `config/graphql_auth0_auth/utils.py` still consumes `sync_remote_user.delay(...)` exactly as before.
+
 ### Fixed
 
+- **`test_superuser_sees_all_queryset` miscounts personal corpuses by 1** (Issue #1394, `opencontractserver/tests/test_visibility_managers.py`, `opencontractserver/tests/test_resolvers.py`): Two `VisibleToUserTests.test_superuser_sees_all_queryset` cases asserted that `Corpus.objects.visible_to_user(superuser).count() == 4` (public + private + 2 personal), but the actual count is 5 because the test DB starts with a pre-existing personal corpus owned by django-guardian's `AnonymousUser` (created during fixture setup before/around the username-based skip in `opencontractserver/users/signals.py::user_created_signal`). The assertion is now scoped to corpuses created by the test's two users (`creator__in=[self.user, self.superuser]`), making it resilient to any fixture-level corpuses that exist at test DB init time. Production code is unchanged.
 - **Merged `frontend` Codecov flag drops to ~33% on every commit where Frontend CI's CT job fails** (`frontend/package.json` `test:coverage:ct`): the script chained `playwright test ... && mkdir -p ... && nyc report ...`, so a failing CT run short-circuited before `nyc report` could turn the per-test JSON files in `.nyc_output` into an `lcov.info`. The downstream `Upload CT Coverage to Codecov` step (`if: success() || failure()`) then errored with "No coverage reports found" and `frontend-component` did not upload for that SHA. Codecov's server-side aggregation of the `frontend` flag was left with only `frontend-unit` (~23%) and `frontend-e2e` (~24%), pulling the merged number down to ~33% even though the previous commit was at ~67% — observed on six consecutive main commits 2026-04-26T01:02..02:58Z (`2d7033f8`..`be5bcfc8`) before recovering on `30298391`. Mirrored the existing `test:e2e:coverage` pattern (`; CT_EXIT=$?; nyc report ... || echo "No coverage data to report"; exit $CT_EXIT`) so `nyc report` runs regardless of test outcome and the lcov ships even on red CT runs. `frontend-component` will still report a slightly lower number when tests fail (failed tests register fewer hits), but it will report — keeping the merged `frontend` flag's denominator stable.
 - **`User.__init__` shared-state mutation re-introduced by branch merge** (`opencontractserver/users/models.py:172-180` removed): PR #1374 (commit `50ed6740`) deleted the `User.__init__` override that mutated `Field.validators[0]` on every instantiation, but a subsequent merge (`b68c1cb4 → 6d2cddbf`) resurrected the override along with its mypy-narrowing changes. The current main on commit `6d2cddbf` therefore reproduced the original `#1358` bug: `User(...)` rebound `username_field.validators[0]` and clobbered any third-party validator prepended to the list. Removed the `__init__` override entirely; the class-body declaration `validators=[UserUnicodeUsernameValidator()]` on the `username` field (still present from PR #1374) is the canonical and only declaration. Also dropped the now-unused `Field` import. Regression coverage from PR #1374 (`opencontractserver/tests/test_user_username_validator.py`) was already on main and is what surfaced the regression in CI.

   - Regression coverage: `opencontractserver/tests/test_corpus_isolation_vector_store.py` — six tests covering cross-corpus leak, deletion-aware drop, orphan-set leak, document-scoped retrieval still returns structural rows, viewer-without-doc-permission excluded, creator still sees own row.
 - **Test-only**: `opencontractserver/tests/test_pydantic_ai_agents.py`, `opencontractserver/tests/test_structural_annotation_portability.py` — `Document.objects.create(...)` calls in `TransactionTestCase` setUp now pass `processing_started=timezone.now()` to short-circuit `process_doc_on_create_atomic`, which would otherwise eagerly chain a Celery PDF-ingest task that fails on the (file-less) test document and aborts the whole test class. Pre-existing failure, exposed cleanly when the regression suite was added.
 
+### Fixed

+- **`Embedding.embedder_path` could be NULL but was typed `str`** (Issue #1357, `opencontractserver/annotations/models.py:461-465`, `opencontractserver/annotations/models.py:584-585`, `opencontractserver/annotations/migrations/0068_enforce_embedder_path_not_null.py`): The Django field was declared `null=True, blank=True` while the Python annotation claimed `str`, causing a long-standing mypy `assignment` error and — more importantly — silently gutting the partial unique constraints added in migration 0059. Each `unique_embedding_per_{document,annotation,note,conversation,message}_embedder` constraint is conditioned on `<parent>__isnull=False` and keys on `(embedder_path, <parent>)`, so any row with `embedder_path IS NULL` bypassed duplicate prevention for its parent. Every production code path that creates an `Embedding` (`Embedding.objects.store_embedding()`, `HasEmbeddingMixin.add_embedding()`, `worker_uploads._store_embeddings()`) already supplies a concrete `embedder_path` or skips creation when empty, so enforcing non-null at the DB level matches actual behaviour rather than constraining it. New migration 0068 backfills any legacy NULL rows with `settings.DEFAULT_EMBEDDER` (deleting rows that would collide with an existing `(default_embedder_path, parent)` row under the partial unique constraint — they were previously unreachable via any query path since all call sites filter on a concrete embedder path), then `AlterField`s the column to `NOT NULL`. Removed the now-unreachable `or 'Unknown Model'` fallback in `Embedding.__str__`. Migration runs with `atomic = False` so the RunPython backfill commits before `AlterField` takes the `ACCESS EXCLUSIVE` lock to set `NOT NULL`, matching the pattern established by migration 0059.
