Chris CoutinhoandClaude Opus 4.8 874c7c109b fix: stop S7632 flagging NOSONAR mentioned in prose comments
SonarCloud's python:S7632 parses the literal ``# NOSONAR`` token wherever it
appears — including inside explanatory comments that *quote* the directive —
and treats the following text as a malformed suppression. The actual bare
``# NOSONAR`` suppression lines are fine; the flagged lines were the prose
comments describing them. Reword those comments to drop the inner ``#`` so the
analyzer no longer sees a directive.

Chris CoutinhoandClaude Opus 4.8 ccfe179a38 fix: well-form NOSONAR suppressions (SonarCloud S7632/S7503)
The new decomposition modules used `# NOSONAR: reason` (colon form), which
SonarCloud flags as a malformed suppression comment (python:S7632) and which
fails to suppress the intended issue. Switch to the repo's bare `# NOSONAR`
convention with the rationale in a comment above, matching config.py and
auth/storage.py. This also lets the suppression silence python:S7503 (async
method without await) on the protocol-required no-op aclose stubs.

Chris CoutinhoandClaude Opus 4.8 7f40f7fdb3 fix(vector-sync): isolate per-app scans so a disabled Notes app can't abort sync
The Notes scan in scan_user_documents ran inline without a try/except, while
files/news/deck each had their own guard. On instances without the Notes app
installed, notes.get_all_notes() raises HTTPStatusError 404, which propagated
out of scan_user_documents and aborted the entire per-user vector sync before
files/news/deck were ever reached -- yielding "0 documents indexed" and, after
5 consecutive errors, stopping the scanner.

Extract the Notes scan into scan_notes() (mirroring scan_news_items /
scan_deck_cards) and wrap the call in a per-app try/except. A 404 (app not
installed/disabled) is now logged at info and skipped; other apps still scan.
Deletion-tracking runs only after a successful Notes fetch, so a failed fetch
can never mass-delete a user's indexed notes.

Chris CoutinhoandClaude Opus 4.8 b5ed1e3b4d fix: address PR #814 review + SonarCloud gate
SonarCloud:
- Resolve 6 S5332 hotspots (http→https in test fixture URLs).
- S6418: hoist the unauthenticated AsyncOpenAI placeholder to a named constant
  + NOSONAR (genuine non-secret; gateway ignores it when unauthenticated).
- Fix two reliability bugs: None-index guard in the gateway token-cache test
  (S2259) and float `> 0.0` instead of `!= 0.0` in the sentinel test (S1244).
- status.py idle path sleeps 0.1s instead of sleep(0) (S7491); NOSONAR on the
  protocol-required async no-await aclose() stubs (S7503).

Claude review:
- Remove three leftover debug print() calls in app.py (logger.info already
  covers them).
- payload_backfill: drop parsed_at from the backfilled-keys docstring (it is
  per-document state, not a deployment scalar); add a clean 404 precondition
  for BasicAuth deployments without an OAuth token verifier.
- status.py: task_status typed TaskStatus | None (drop type: ignore).
- nats.py: TODO to thread etags for file/deck/news; note etag default → None.
- factory: warn on unknown INGEST_BUS_URL scheme; raise ValueError instead of
  assert for the external-mode preconditions.
- docs/configuration.md: document the decomposition hook-point env vars + that
  nats-py ships core (lazy-imported) and external+bus uses two NATS connections.

Chris CoutinhoandClaude Opus 4.8 063bd06ba6 fix: cache app-password storage to avoid per-request Alembic upgrade race
get_user_client_basic_auth built a fresh RefreshTokenStorage and ran
storage.initialize() — a full Alembic `upgrade` in a worker thread — on every
call. Once the /api/v1 search endpoints (unified_search, vector_search) and the
chunk-context endpoint were wired to use it, concurrent requests ran concurrent
Alembic upgrades, which race on Alembic's non-thread-safe module-global
EnvironmentContext proxy and intermittently raise `KeyError: 'script'` →
HTTP 500 (seen on multi-user-basic/nc31; nc32 got lucky).

Cache one process-wide, already-initialized storage instance behind a lazily
created anyio.Lock so the one-time migration runs exactly once and never races.
Callers passing an explicit `storage` are unaffected. Also removes a redundant
per-request migration from the search hot path.

Chris CoutinhoandClaude Opus 4.8 cafbfd15a9 fix: address PR #813 review (owner_id index, cache bound, explicit param)
- vector/qdrant_client.py: add owner_id to _PAYLOAD_INDEX_FIELDS (BLOCKING).
  Every search applies MatchAny(key="owner_id", ...); without a keyword index
  Qdrant full-scans the collection and may 400 on Qdrant Cloud strict mode.
  _ensure_payload_indexes is idempotent so existing collections migrate at
  startup.
- search/access_filter.py: bound the process-global _owners_cache with an LRU
  cap (was one unbounded entry per active user, never evicted); document the
  owner-level over-fetch limitation (a prolific sharer floods the recall
  buffer with ghost candidates that verify-on-read drops, with no second
  Qdrant pass) as a TODO toward per-file filtering.
- search/algorithms.py + semantic.py + bm25_hybrid.py: promote
  accessible_owners from **kwargs to an explicit keyword-only parameter on the
  SearchAlgorithm ABC and both implementations, so a misspelled keyword is a
  type error rather than a silent fall back to self-only scope.
- search/verification.py: document that _verify_files now verifies by global
  file id (WebDAV SEARCH), not by path.
- tests/unit/search/test_access_filter.py: add cache-hit, TTL-expiry,
  failure-not-cached, and LRU-bound tests.

Bumps the astrolabe submodule with the matching #89 review fixes.

Chris CoutinhoandClaude Opus 4.8 d883052fb8 feat: add opt-in MCP decomposition hook points (design §10)
Adds the seven §10.2 hook-point modules + five env vars so Astrolabe Cloud can
offload document processing to the external document-processor / embedding
gateway. Purely additive: with every setting unset the server behaves exactly
as today, so self-hosters are unaffected (Deck #92).

Hook points (all default to current monolith behavior):
- config: EMBEDDING_PROVIDER, INGEST_MODE, STATUS_BACKEND,
  COLLECTION_METADATA_SOURCE, FACT_EVENT_EMITTER (+ supporting settings),
  validated in Settings.__post_init__ (fail-fast STATUS_BACKEND=local with
  INGEST_MODE=external); shared canonical.py.
- vector/payload_keys.py + acl_hash.py: cross-impl NAMESPACE/point_id (§2.2)
  and BLAKE2b-128 ACL hash (§11), pinned by fixtures shared with the
  document-processor repo.
- embedding/gateway_client.py: OpenAI-compatible GatewayProvider authenticating
  via M2M OIDC client-credentials (separate realm); manual-only registry entry.
- vector/collection_metadata.py: sentinel-point / API metadata source with env
  fallback.
- vector/queue/: hexagonal ingest producer ports + memory/NATS adapters
  (Postgres seam); INGEST_MODE=external publishes mcp.ingest.requested.{tenant}
  instead of the in-memory stream and skips the in-process processor pool. The
  lifespan becomes a composition root across both deployment branches.
- vector/queue/status.py: STATUS_BACKEND=bus subscriber feeding a StatusStore
  the vector-sync status endpoint reads.
- admin/payload_backfill.py: POST /api/v1/admin/payload-backfill (admin scope);
  processor writes the new payload keys; query-side ACL pre-filter gated behind
  ACL_PREFILTER_ENABLED (default off).

Chris CoutinhoandClaude Opus 4.7 37db82613d feat(search): ACL-aware vector filter via Nextcloud Shares lookup
The vector index has always been strictly per-user: every Qdrant payload
carries a `user_id` and the search filter is `user_id == querying_user`.
A file Alice indexed cannot be discovered by Bob even if she has shared
it with him — Bob would have to re-index it under his own user_id to
make it searchable, which means duplicate index entries for every share
recipient.

Switch to ownership-with-ACL-expansion:

- New `nextcloud_mcp_server.search.access_filter` module:
  - `list_accessible_owners(sharing_client, user_id)` calls the OCS
    Sharing API (`shared_with_me=true`) and returns
    `{user_id} ∪ {uid_owner of each share}`. Fails open to `[user_id]`
    so a misbehaving Sharing API doesn't black-hole search.
  - `build_ownership_filter(user_id, accessible_owners)` returns a
    Qdrant `Filter` whose `should` branch matches either the new
    `owner_id IN accessible_owners` field or the legacy `user_id` field.
    The legacy branch keeps points indexed before this change reachable
    without a migration backfill.
- Indexer payload (`vector/processor.py`) now writes `owner_id` alongside
  `user_id`. `DocumentTask` gains an optional `owner_id` field; today the
  scanner always runs as the owner so the processor falls back to
  `user_id`, but the field is plumbed so a future shared-with-me crawler
  can set the true owner without reshaping the payload contract.
- `SemanticSearchAlgorithm.search` and `BM25HybridSearchAlgorithm.search`
  accept `accessible_owners` via kwargs and use the new ownership filter.
  Default behaviour with no kwarg is unchanged (self-only).
- Both user-facing callers — the MCP tool path (`server/semantic.py`) and
  the visualization Starlette route (`auth/viz_routes.py`) — compute
  `accessible_owners` from the authenticated Nextcloud client before
  invoking the search algorithm. Eviction, scanner deletion, placeholder,
  and chunk-context paths intentionally keep the legacy `user_id`
  semantics (those are "operations on a specific user's records", not
  cross-user reads).
- 10 new unit tests in `tests/unit/search/test_access_filter.py` cover
  self-only default, owner expansion, dedup, fallback fields, OCS
  failure, and the legacy `should`-branch shape.

Pairs with cbcoutinho/astrolabe#89 — together they let an Astrolabe user
find content owners have shared with them without going through any
re-authorization flow or re-indexing.

feat(webhooks): add Deck card sync preset with vector indexing
2026-05-24 12:42:18 +02:00
Chris CoutinhoandClaude Opus 4.7 c03223a41c fix(vector-sync): use resolved collection name in orphan sweep
The startup sweep was reading settings.qdrant_collection (the raw config
value, default "nextcloud_content") instead of settings.get_collection_name(),
which is what every other vector-sync operation uses. When QDRANT_COLLECTION
is not overridden, get_collection_name() auto-generates a
{deployment-id}-{model-name} name; the sweep was targeting a non-existent
collection and silently returning (0, 0).

Also adds the AsyncQdrantClient type annotation that was missing on
sweep_orphan_placeholders, and renames its parameter from collection_name
to collection to make it clear the value must be the resolved name.

Chris CoutinhoandClaude Opus 4.7 a5cbe91b29 fix(vector-sync): sweep placeholder orphans at Pod startup (#101)
When the per-tenant nextcloud-mcp-server Pod OOMKills mid-batch, the
in-memory anyio processor queue is lost but the placeholder Qdrant
points (is_placeholder=true, status=pending) survive. The next Pod's
scanner re-runs, sees the existing placeholders, applies the
5 × VECTOR_SYNC_SCAN_INTERVAL staleness gate (~5h with the deployed
1h scan interval), and skips them. Result: 0 documents indexed for
the duration of the gate after every restart.

Stamps a process-level instance_id (UUID per Pod-process) onto every
placeholder write. A new sweep_orphan_placeholders helper, called
once from starlette_lifespan after the Qdrant client is initialised
and before the scanner / user-manager spawns, scrolls the collection
and deletes any placeholder whose instance_id doesn't match the
current Pod's (including placeholders with no instance_id field —
back-compat for pre-fix Pod versions). The scanner's next cycle
naturally re-creates fresh placeholders and queues work normally;
no DocumentTask reconstruction needed.

Sweep is one-shot at startup, not periodic — the existing staleness
gate still covers same-Pod recovery, and the cross-Pod-restart gap
was the only failure mode. Failure is non-fatal (logged via
vector_sync.orphan_sweep_failed) so a transient Qdrant hiccup at
boot doesn't prevent the scanner from running.

Both lifespan branches (single-user BasicAuth, OAuth / multi-user
BasicAuth) call the sweep via a module-local helper. A new
VECTOR_SYNC_ORPHAN_SWEEP_ENABLED setting (default True) provides
an escape hatch.

Closes Deck #101.

Chris CoutinhoandClaude Opus 4.7 fdcbd7bd3f feat(webhooks): add Deck card sync preset with vector indexing
Nextcloud Deck PR #7910 added IWebhookCompatibleEvent to CardCreated/
Updated/DeletedEvent and BoardUpdatedEvent, so Deck can finally emit
real-time webhooks via core's webhook_listeners app. Wire this into
the existing preset → parser → DocumentTask pipeline that already
backs Notes / Calendar / Tables / Forms / Files sync.

- Add deck_sync preset (app=deck, 4 events) and drop the stale
  "Deck does not support webhooks" comment.
- Teach webhook_parser to convert Deck card events into
  DocumentTask(doc_type=deck_card, operation=index|delete) with
  stack_id metadata. BoardUpdatedEvent logs delivery at INFO and
  returns None — the polling scanner reconciles affected cards.
- Cover three new unit tests for the deck create/delete/board-update
  paths plus symmetric fail-open tests for missing card.id /
  node.id in _parse_deck_event and _parse_file_event.

The astrolabe admin UI auto-discovers the new preset via
filter_presets_by_installed_apps(); no astrolabe-side wiring is
required for it to appear in the Webhook Management card grid.

Note: requires Deck ≥1.18.x (where PR #7910 lands); the preset is
hidden when the Deck app isn't installed.

Chris CoutinhoandClaude Opus 4.7 e0b7afb4b1 fix(embedding): instantiate BM25 singleton off the event loop
The ``BM25SparseEmbeddingProvider.__init__`` calls
``fastembed.SparseTextEmbedding(model_name="Qdrant/bm25")`` which
downloads ~50 MB of model weights from HuggingFace and loads them
into memory — observed >5 s wall-clock in production. The inference
methods (``encode_async``, ``encode_batch_async``) already wrap work
in ``anyio.to_thread.run_sync``, so the design intent is clearly to
keep FastEmbed off the event loop. That protection just didn't
cover the constructor.

Symptom in the Astrolabe Cloud per-tenant deploy (deck #102 smoke):
~30–90 s after a user enables semantic search, the pod tips into a
SIGKILL-restart cycle. Loki shows a single log line

  Initializing BM25 sparse embedding provider: Qdrant/bm25

followed by nothing else from the event loop until exitCode 137.
Kubernetes ``/health/live`` httpGet probe timeout=5s fires 6 times
in a row, kubelet kills the container, restart, repeat.

Fix: switch ``get_bm25_service()`` to an async accessor that wraps
the first-time construction in ``anyio.to_thread.run_sync``. Two
existing call sites (``vector/processor.py:603``,
``search/bm25_hybrid.py:123``) update to ``await``. Both are
already inside async functions so the await is free.

New unit test pins the invariant by monkey-patching
``BM25SparseEmbeddingProvider.__init__`` with ``time.sleep(1)`` and
asserting a concurrent ``anyio.sleep(0.05)`` finishes promptly —
the test fails if the constructor ever runs back on the event loop.

Same pattern exists in ``OllamaEmbeddingProvider.__init__`` (sync
``httpx.get`` health-check). Ollama isn't enabled in any current
deploy; filed as a follow-up.

Refs:
- Astrolabe Cloud deck card #102 (smoke discovery)
- Sibling fix #799 (NullPool for cross-loop-asyncpg, same class
  of "anyio bites you in production" bug)

Verified:
- ``uv run pytest tests/unit/`` — 1027 passed
- ``uv run ruff check`` clean on touched files
- ``uv run ty check`` clean on touched files
- New tests pass

Chris CoutinhoandClaude Opus 4.7 65345fd6eb refactor: drop OAuth-refresh background-sync path from oauth_sync.py
Follow-up to #787/#789 (ADR-022 cleanup). After
`oauth_enabled ↔ enable_login_flow` became an invariant, the
`use_basic_auth=False` branch in `vector/oauth_sync.py` — and the
parameter wiring that fed it — was no longer reachable from any
supported deployment mode. This commit removes the dead code.

- nextcloud_mcp_server/vector/oauth_sync.py:
  - Deleted `get_user_client_oauth` (the OAuth-token refresh helper) and
    its `VECTOR_SYNC_SCOPES` constant.
  - Deleted the `get_user_client` dispatcher. Internal callers now call
    `get_user_client_basic_auth` directly.
  - Dropped the `use_basic_auth: bool` parameter from `user_scanner_task`,
    `multi_user_processor_task`, `_run_user_scanner_with_scope`, and
    `user_manager_task`.
  - Dropped the `token_broker` parameter from the same four functions —
    they no longer need it now that the OAuth-refresh path is gone. The
    `TokenBrokerService` constructed in `app.py` is still used by the
    management API revoke endpoint, just not by background sync.
  - Simplified the user-list query in `user_manager_task` to always read
    from the `app_passwords` table.
  - Replaced all `mode_label = "BasicAuth" if use_basic_auth else "OAuth"`
    with a literal `[BasicAuth]` log prefix (keeps existing log filters
    working).
  - Updated the module docstring to describe the post-cleanup shape.
  - Dropped the now-unused `TYPE_CHECKING` import of `TokenBrokerService`.

- nextcloud_mcp_server/app.py: dropped the `use_basic_auth = True` block
  and the now-stale `token_broker if not use_basic_auth else None` /
  `use_basic_auth` positional args from the two `tg.start(...)` calls in
  the multi-user vector-sync lifespan. Token broker construction stays —
  still consumed by the management API revoke endpoint via
  `app.state.oauth_context["token_broker"]`.

- tests/integration/test_app_password_provisioning.py: deleted four tests
  that exercised the now-removed OAuth-refresh path
  (`test_oauth_mode_uses_refresh_token_only`,
  `test_oauth_mode_raises_error_without_token`,
  `test_get_user_client_oauth_function`,
  `test_oauth_mode_requires_token_broker`) plus the
  `test_get_user_client_dispatches_to_basic_auth` test for the deleted
  dispatcher. Updated the module docstring + imports accordingly. The
  BasicAuth-mode tests (`test_basic_auth_mode_uses_local_storage`,
  `test_multiple_users_basic_auth_mode`, etc.) all remain.

No runtime-behaviour change in any supported deployment mode — the deleted
branches were already unreachable post-PR #787. 3 files changed,
+59 / -301; 1010 unit tests pass; integration jobs for
`mcp-login-flow` and `mcp-multi-user-basic` are the critical regression
gates before merge.

Chris CoutinhoandClaude Opus 4.7 665cb9b1eb refactor: convert f-string logging to lazy %-style format (G004)
Sweep all 1676 G004 violations across 112 files, converting
`logger.<level>(f"…{x}…")` to `logger.<level>("…%s…", x)`.

Why: ruff rule G004 was added to pyproject.toml to enforce lazy
%-style logging — defers formatting until the log level is enabled
and lets structured log tooling match the unformatted template.

Conversion preserves rendered output byte-for-byte:
- `{x}` → `%s` + `x`
- `{x!r}` / `{x!s}` / `{x!a}` → `%r` / `%s` / `%a`
- Format specs (`{x:.2f}`, `{x:>10}`) → `%s` + `format(x, 'spec')`
  (printf-style specs aren't 1:1 with Python format specs, so we
  delegate to `format()` to keep identical output)
- Literal `%` → `%%`
- Concatenated f-strings (`f"a {x} " "b"`) flattened
- Trailing kwargs (`exc_info=True`) preserved

Verified:
- `uv run ruff check --select G004` → 0 violations
- `uv run ty check -- nextcloud_mcp_server` → passes
- `uv run pytest tests/unit/` → 1010 passed

Chris CoutinhoandClaude Opus 4.7 282c245da1 refactor(config)!: drop ENABLE_MULTI_USER_BASIC_AUTH env var, fail loud on legacy aliases
Same pattern as the ENABLE_LOGIN_FLOW removal in the previous commit:
the deployment mode (MCP_DEPLOYMENT_MODE) is the single source of truth
for selecting an auth flow. The ENABLE_MULTI_USER_BASIC_AUTH env-var
alias is redundant with `MCP_DEPLOYMENT_MODE=multi_user_basic`.

Unlike the ENABLE_LOGIN_FLOW removal — where silent removal was safe
because Login Flow v2 is the auto-detection default — silent removal
here would be a surprise: a user with only ENABLE_MULTI_USER_BASIC_AUTH=true
in their .env would auto-detect into LOGIN_FLOW after upgrade (wrong
runtime mode). Mitigation: detect_auth_mode now reads os.environ
directly for both legacy aliases and raises ValueError with a one-line
migration message if either is set. Applied retroactively to
ENABLE_LOGIN_FLOW as well — loud is better than silent.

- nextcloud_mcp_server/config.py:
  - Drop the dynaconf env-var alias entry for ENABLE_MULTI_USER_BASIC_AUTH.
  - Update the `enable_multi_user_basic_auth` field docstring to mark it
    as derived / not user-settable.
  - `_is_multi_user_mode()` (early-config helper, runs before Settings
    is built) switched to checking MCP_DEPLOYMENT_MODE directly. Now
    consistent with the canonical detection in detect_auth_mode.
- nextcloud_mcp_server/config_validators.py:
  - Drop the auto-detection branch (`if settings.enable_multi_user_basic_auth`).
    Selection of MULTI_USER_BASIC is now exclusively via the explicit
    MCP_DEPLOYMENT_MODE branch.
  - Add `enable_multi_user_basic_auth` to `_sync_derived_flags` alongside
    `enable_login_flow` — both flags are now derived from the resolved mode.
  - Drop `enable_multi_user_basic_auth` from
    `MODE_REQUIREMENTS[MULTI_USER_BASIC].required` and from the
    `forbidden` lists of SINGLE_USER_BASIC and LOGIN_FLOW (no longer
    user input → no meaningful forbidden check).
  - Add loud-deprecation `ValueError` block at the top of detect_auth_mode
    that errors with a clear migration message when ENABLE_MULTI_USER_BASIC_AUTH
    or ENABLE_LOGIN_FLOW is found in os.environ.
- tests/unit/test_config_validators.py:
  - Switch ~10 fixtures from `enable_multi_user_basic_auth=True` to
    `deployment_mode="multi_user_basic"` (mirrors `enable_login_flow`
    treatment from the previous commit).
  - Switch two `patch.dict(os.environ, {"ENABLE_MULTI_USER_BASIC_AUTH": "true"})`
    blocks to use MCP_DEPLOYMENT_MODE.
  - Rename `test_forbidden_multi_user_basic_auth` to
    `test_forbidden_multi_user_basic_when_credentials_present` — the
    scenario is now an explicit-mode + credentials conflict, not an
    env-var-flag conflict.
  - Add `test_legacy_enable_multi_user_basic_auth_env_var_errors` and
    `test_legacy_enable_login_flow_env_var_errors` to exercise the new
    loud-deprecation ValueError path.
- docker-compose.yml: mcp-multi-user-basic profile switched to
  `MCP_DEPLOYMENT_MODE=multi_user_basic`.
- env.sample: replaced `#ENABLE_MULTI_USER_BASIC_AUTH=true` example with
  `#MCP_DEPLOYMENT_MODE=multi_user_basic`.
- docs/authentication.md, configuration.md, troubleshooting.md,
  auth-flows.md, webhook-management-guide.md,
  configuration-migration-v2.md, ADR-025: replaced env-var examples
  with the canonical MCP_DEPLOYMENT_MODE form.
- docs/ADR-020: marked partly superseded by ADR-022.
- CLAUDE.md: Multi-User BasicAuth section updated to set
  MCP_DEPLOYMENT_MODE.
- nextcloud_mcp_server/vector/oauth_sync.py: module docstring updated.

BREAKING CHANGE: ENABLE_MULTI_USER_BASIC_AUTH is no longer read from
the environment, and setting it now raises a startup ValueError with
a migration message. Replace `ENABLE_MULTI_USER_BASIC_AUTH=true` with
`MCP_DEPLOYMENT_MODE=multi_user_basic`. The same loud-deprecation
check is also applied to the recently-removed ENABLE_LOGIN_FLOW —
replace with `MCP_DEPLOYMENT_MODE=login_flow` (or drop both;
`login_flow` is the auto-detect default when no other auth env vars
are set).

Chris CoutinhoandClaude Opus 4.7 8246d9a088 fix(vector): address PR review round 17 + local-mode collection-creation regression
Round 17 reviewer (🟡 Important):

1. docs/configuration.md degraded-migration runbook said `doc_id backfill
   failed on …` but the actual log line in qdrant_client.py:415 is
   `doc_id backfill scroll failed on …`. Operators grepping the runbook
   string would have missed it. Insert the `scroll` qualifier.

2. _create_one_payload_index returned True on the 400 schema-conflict
   path, so a wrong-type index discovered at create time skipped the
   consolidated `Payload index creation incomplete` summary — but a
   wrong-type index discovered via the existing-schema check at line
   195-206 did fire it. Tenants whose payload_schema is hidden from
   their JWT (Qdrant Cloud collection-scoped tokens) only ever observe
   the create-time path, so they never saw the operator-level summary.
   Return False so the summary fires in both cases.

3. docs/configuration.md said the upgrade-time delay was `proportional to
   point count while writes are issued` — overstating the cost. Writes
   are proportional to int-typed points only; the scroll itself is
   proportional to total point count. Reword.

Local-mode collection-creation regression (root-cause of failing
single-user / login-flow / multi-user-basic CI jobs):

PR #779 changed the existence probe in get_qdrant_client from
collection_exists() (returned bool in both modes) to get_collection()
+ except UnexpectedResponse(status_code=404). The HTTP-mode client
raises UnexpectedResponse with a 404 body, but the local/in-memory
client raises ValueError(f"Collection {name} not found") — see
qdrant_client/local/async_qdrant_local.py. The narrow except clause
let the ValueError propagate, app.py's lifespan re-raised as
RuntimeError, and the mcp container crashed on first start. Catch
ValueError too, with a `not found` substring guard so genuine
programming bugs (bad collection_name, etc.) still surface.

Tests: extend the existing 400-path test to assert the new
failed_fields contract; add two get_qdrant_client unit tests pinning
the local-mode VE catch (positive case + propagation case).

Chris CoutinhoandClaude Opus 4.7 8f4f5c0079 fix(vector): address PR review round 16 — type-aware index check, comments
Detect pre-existing payload indexes with the wrong schema type in
`_ensure_payload_indexes`. The previous "field already in
existing_schema → skip" branch silently survived a collection migrated
from the int-doc_id era where `doc_id` is indexed as INTEGER, letting
`MatchValue(value="123")` searches keep failing with HTTP 400 on Qdrant
Cloud strict mode — exactly the production failure this PR was meant to
fix. New behaviour: compare `existing_schema[field].data_type` against
the declared type; on mismatch log a WARNING and append to
`failed_fields` so the consolidated end-of-function summary picks it up.
No auto-repair (operator intervention only — see docs/configuration.md
recovery procedure). New test exercises the doc_id-INTEGER scenario
end-to-end and asserts both the per-field WARNING and the summary line.

Clarify the `_verify_news_items` malformed-doc_id rationale: the news
API has no per-item endpoint, so a malformed doc_id genuinely cannot be
verified against the source of truth. We err toward false-positive
(keep) over false-negative (drop) — same conservative posture as
`_verify_notes` and `_verify_deck_cards`. The producer-side validation
is the real security boundary; the verifier is defence-in-depth. Both
the inline comment and the WARNING message now spell this out.

Add a TODO in `get_last_indexed_timestamp` flagging the O(N) cost on
every incremental sync tick. The previous single-page `limit=10_000`
silently bounded the scroll; paginating fixed correctness but made the
unbounded cost visible. The follow-up tracker (canonical TODO at
`api/visualization.py`) covers migrating the max-`indexed_at` to a
sentinel point or collection metadata for O(1) lookup.

Consolidate the duplicate non-numeric-doc_type TODOs at
`api/visualization.py:508` and `auth/viz_routes.py:570` into a single
canonical comment in `visualization.py`; `viz_routes.py` is reduced to
a back-reference. Removes the rot risk of "fixed in one place,
forgotten in the other." The canonical comment also references the
O(1) timestamp follow-up in `scanner.py`.

Document the `batch_size = 256` (qdrant_client.py) vs
`_DELETION_TRACKING_PAGE_SIZE = 1024` (scanner.py) split with
cross-referencing comments at each site: the smaller batch is for the
read-write backfill upsert path (Qdrant accepts ~256-point chunks
comfortably); the larger page is for read-only deletion-tracking
scrolls where no per-page write round-trip applies.

Replace `assert qdrant_client is not None` in `scan_user_documents`
with `cast(AsyncQdrantClient, qdrant_client)` plus an explanatory
comment. `assert` is silently elided under `-O`; `cast` is the
conventional zero-cost narrower for branches the type checker can't
infer from the surrounding `if not initial_sync` ternary.

Chris CoutinhoandClaude Opus 4.7 04bc2325f2 fix(qdrant): use get_collection for startup probe (multi-tenant safe, take 2)
Follow-up to PR #778 — `collection_exists()` is also denied by Qdrant
Cloud on a collection-scoped JWT, so the multi-tenant fix needs to go
one step further: use `get_collection(name)` (the underlying GET
`/collections/{name}` call) and treat a 404 `UnexpectedResponse` as
the "doesn't exist" signal. That endpoint is the only existence-probe
Qdrant permits on a collection-scoped JWT — listing or probing
collection metadata cluster-wide is a tenant-isolation boundary by
design.

Hit during Astrolabe Cloud smoke17 with the post-#778 image:

    qdrant_client.http.exceptions.UnexpectedResponse: 403 (Forbidden)
    raw response: {"error":"forbidden"}
    File "qdrant_client.py", line 84, in get_qdrant_client
        collection_present = await _qdrant_client.collection_exists(...)

Folds the existence check into the same `get_collection()` call that
already runs immediately afterward for dimension validation, so the
new path is also one fewer round-trip on the happy path.

Cold-start (collection genuinely missing) behavior is unchanged: 404
→ `collection_info` is None → fall through to `create_collection()`.
Whether `create_collection` succeeds is an orthogonal concern (managed
multi-tenant setups pre-provision collections externally; admin-key
single-tenant setups can create on the fly).

Chris CoutinhoandClaude Opus 4.7 f2d4982b2f fix(qdrant): use collection_exists for startup probe (multi-tenant safe)
The startup path in `get_qdrant_client()` calls `get_collections()` to
check whether the configured collection already exists. That's a
cluster-wide list operation; in managed multi-tenant Qdrant Cloud
deployments where each tenant's JWT is scoped to a single collection
(by design — `access: [{"collection": "tenant_<id>", "access": "rw"}]`),
the call returns `403 Forbidden` and the FastAPI lifespan crashes:

    qdrant_client.http.exceptions.UnexpectedResponse: 403 (Forbidden)
    raw response: {"error":"forbidden"}
    RuntimeError: Cannot start vector sync - Qdrant initialization failed

Switching to `collection_exists(collection_name)` (per-collection
HEAD-style probe) only requires access to the named collection, which
the tenant JWT has. Single-tenant deployments using an admin/master
key are unaffected — they had access to both forms; this picks the
narrower one.

Doesn't change creation semantics: when the collection isn't present
the code path still calls `create_collection`. In a managed setup
where the collection is pre-provisioned by an external admin (e.g.,
the Astrolabe Cloud control plane's create-tenant workflow), that
branch never fires for an existing tenant; cold-start tenants get
their collection created by the workflow before the Pod boots.

Chris CoutinhoandClaude Opus 4.7 68506f96c5 fix(vector): address PR review round 15 — concurrency, pagination, stale coercion
Defer publication of `_qdrant_client` until after the in-lock backfill +
payload-index migration awaits complete. The fast-path check at the top of
`get_qdrant_client` reads the singleton without holding the init lock, so
publishing the constructed-but-unmigrated client let concurrent fast-path
callers fire filtered searches before `_ensure_payload_indexes` ran —
producing HTTP 400 ("Index required but not found") on Qdrant Cloud strict
mode. Local `provisional` is now used for every await inside the lock; the
global is assigned exactly once, last.

Replace the five hand-rolled `scroll(..., limit=10000)` calls in
`vector/scanner.py` (notes / files / news / deck-cards deletion tracking,
plus the timestamp scroll) with a single paginated `_scroll_all_points`
helper. The previous single-page cap silently dropped deletion-tracking
points beyond the first 10 k for any user past that threshold. Pagination
follows Qdrant's documented contract (loop until `next_page_offset is
None`) with a fixed per-page `_DELETION_TRACKING_PAGE_SIZE = 1024`.

Extract `_create_one_payload_index` from `_ensure_payload_indexes` to drop
its cognitive complexity below the SonarQube limit (17 → ≤ 15) without
losing the per-field error-containment rationale; every comment is
preserved verbatim on the helper.

Drop the stale `SearchResult.id` `int | str` comment and the redundant
`str(d)` coercion in `_verify_news_items` — the contract has been
str-only since the producer-side stringification landed earlier in this
PR.

Fix eight `doc_id=<int>` test calls in `test_chunk_context_offset_gate.py`
that violated the `doc_id: str` signature of `get_chunk_with_context`,
plus align `_make_result` in `test_verification.py` to coerce `id=str(...)`
matching the production contract — and update 30+ assertions from int
sets (`{1, 2, 3}`) to str sets (`{"1", "2", "3"}`) so the tests now model
the post-PR `SearchResult.id: str` reality end-to-end. Previously these
were masked by the `str(d)` coercion now removed from production.

- search/context.py: drop the doc_type=='file' guard on skip_offset_lookup

  fallback when chunk_index is available. Legacy chunk_index=None data

  file-scroll block doesn't depend on a name bound inside the
  notes-scroll block.
- tests/unit/test_chunk_context_offset_gate.py: flip the note-with-

Chris CoutinhoandClaude Opus 4.7 47c531969f fix(vector): address PR review round 10 — index chunk_index, harden index loop, lazy-init lock
Three coordinated fixes flagged as Important in the round-10 review of
PR #773:

1. Index chunk_index. The chunk-context fast path in
   _get_chunk_by_index_from_qdrant and get_chunk_bbox_and_page_from_qdrant
   filters on chunk_index, but the field was absent from
   _PAYLOAD_INDEX_FIELDS. On Qdrant Cloud strict mode every chunk-context
   lookup via chunk_index would 400 and silently fall back to the
   document re-fetch path — the exact failure mode the chunk_index
   shortcut exists to avoid. Added as INTEGER schema.

2. Catch raw network errors in _ensure_payload_indexes. The
   create_payload_index loop only caught UnexpectedResponse, so an
   httpx.ConnectError or asyncio.TimeoutError mid-loop would propagate
   uncaught — leaving _qdrant_client assigned and silently skipping all
   remaining fields. Added a broad Exception catch with the same
   per-field containment as the 5xx path: log at ERROR with exc_info,
   append to failed_fields, continue. New test covers the path.

3. Lazy-initialise _qdrant_init_lock. Constructing anyio.Lock() at
   module import time works for the asyncio backend but anyio's docs
   advise instantiating synchronization primitives within an async
   context, and pyproject.toml's anyio_mode = "auto" means tests can
   run under trio. Moved the construction into get_qdrant_client; safe
   under cooperative multitasking because there is no await between the
   None-check and the assignment.

Chris CoutinhoandClaude Opus 4.7 fec1596784 fix(vector): address PR review round 9 — drop redundant guard, add init lock, test float doc_id path
Addresses the four 🟡 important findings from claude-bot review on PR #773:

str (non-Optional) and the guard would silently skip the Qdrant lookup
for an empty string. Removing the guard matches the type signature.

(`all([…, doc_id, …])` rejects None and empty string, plus
`assert doc_id is not None`). No code change needed.

`get_qdrant_client()` with a module-level `anyio.Lock`. Double-checked
locking keeps the steady-state hot path lock-free. Without this,
parallel cold-start callers could all enter the init block and run
`_backfill_doc_id_to_string` + `_ensure_payload_indexes` redundantly
(idempotent, but noisy). Pattern matches `auth/storage.py:2071`.

behavior with three tests covering the float-warning path (the gap
called out in the review), the str/None silent-skip paths, and the
int-grouping happy path.

Verification:
- ruff check / format: clean

Chris CoutinhoandClaude Opus 4.7 64f0842977 fix(vector): guard _group_int_doc_ids against non-int doc_id values
Skip and warn instead of stringifying floats / unexpected types in the
backfill helper. A stray doc_id=3.0 would otherwise be rewritten to
"3.0", which producers (str(int)) and the keyword index would never
match, and which int() on the verification side would reject. Also add
a doc_id=0 case to the backfill test to guard against a future
falsy-skip regression.

Chris CoutinhoandClaude Opus 4.7 d390b3a4b8 fix(vector): address PR review round 8 — anyio convention + cosine-safe sentinel + dedup get_collection
Reviewer findings (1 blocking + 2 important):

- 🔴 Replace `import asyncio` / `await asyncio.sleep(0)` with
  `import anyio` / `await anyio.sleep(0)` in the four async side-effect
  helpers (_scroll_raises, _upsert_raises, _get_collection_raises,
  _create_index). CLAUDE.md mandates anyio for all async operations;
  conftest pins the backend to asyncio so the asyncio.sleep call worked
  today, but the inconsistency would surface the moment that pin moves.
- 🟡 Replace the sentinel's zero dense vector with a single non-zero
  element (`[1e-9] + [0.0] * (dimension - 1)`). Cosine distance is
  mathematically undefined for the zero vector and Qdrant Cloud strict
  mode rejects zero-vector upserts. The exact value doesn't matter
  (sentinel never participates in a search — no user_id/doc_id/doc_type
  payload) but the upsert itself must be valid.
- 🟡 Avoid the duplicate `get_collection` round-trip on every restart.
  `_ensure_payload_indexes` now accepts an optional
  `existing_schema: dict | None` parameter; when None it fetches
  collection_info itself (and the get_collection-failure swallow still
  applies), but `get_qdrant_client` already fetches collection_info
  for dimension validation in the existing-collection branch — pass
  `collection_info.payload_schema or {}` through to skip the second
  call. The new-collection branch passes `existing_schema={}`
  explicitly since a freshly created collection has no payload schema.

The 🟡 deck_card iteration-fallback finding doesn't apply: the
`isdigit()` guard at context.py:612 returns early before either the
fast-path or the iteration fallback runs, so non-numeric doc_ids
cannot reach the inner `c.id == int(doc_id)` comparison.

Chris CoutinhoandClaude Opus 4.7 d00779ce79 fix(vector): add BOOL index for is_placeholder + correct wait=True docstring
Reviewer feedback (2 items):

- Add a BOOL payload index for `is_placeholder` alongside the three
  KEYWORD fields. Strict-mode index-required filtering on Qdrant Cloud
  enforces a payload index on any field used in a `FieldCondition`
  regardless of value type, so `get_placeholder_filter` and
  `delete_placeholder_point` would have produced HTTP 400 on Cloud
  instances even after this PR's KEYWORD fix.

  Implementation: replace `_KEYWORD_PAYLOAD_FIELDS: tuple` with
  `_PAYLOAD_INDEX_FIELDS: dict[str, PayloadSchemaType]` so each
  field carries its own schema type. Rename
  `_ensure_keyword_payload_indexes` to `_ensure_payload_indexes` since
  the function now creates more than just KEYWORD indexes. The
  per-field log line now includes the schema type
  ("Created KEYWORD payload index on 'doc_id'", "Created BOOL payload
  index on 'is_placeholder'") so operators can tell which type was
  created without checking the source.

- Correct the misleading `wait=True` docstring in
  `_apply_backfill_writes`. The previous wording said
  `_ensure_payload_indexes` runs "immediately after this function",
  but `_apply_backfill_writes` is called in a loop inside
  `_backfill_doc_id_to_string` — the index creation runs after the
  backfill function *returns*, not after each write. Rewrote the
  docstring to capture both load-bearing reasons:
  (1) per-batch commit ordering for crash-recovery safety, and
  (2) ensuring the keyword index built later covers committed
  payloads only.

Adds `test_ensure_payload_indexes_includes_is_placeholder_as_bool`
asserting the schema type is BOOL specifically. Existing tests
updated to use the new dict-based registry (side_effect lists now
extend to all four entries; field-set assertions derive from the
registry instead of hardcoding 3 KEYWORD names).

Chris CoutinhoandClaude Opus 4.7 60a9882c92 fix(vector): address PR review round 6 + SonarCloud findings
Reviewer feedback (3 important + 3 nits):

- Wrap _ensure_keyword_payload_indexes' get_collection() call in
  try/except. The qdrant_client singleton is already assigned by the
  time this function runs, so a transient timeout/DNS failure
  propagating out left the process holding a usable client with the
  migration silently skipped on every subsequent call. Now logs ERROR
  with exc_info and returns; next process restart retries.
- Add `and "doc_id" in point.payload` guard to the four set
  comprehensions in scanner.py (indexed_doc_ids, indexed_file_ids,
  indexed_item_ids, indexed_card_ids). Previously a payload missing
  the doc_id key would raise KeyError and crash the entire scan.
- Tighten test_ensure_keyword_payload_indexes_logs_400_as_warning to
  match the per-field warning prefix exactly (`startswith("Schema
  conflict on payload index")`), so a future change adding 400s to
  the partial-failure summary surfaces here as a count mismatch.
- Add new-collection vs existing-collection context to the
  _backfill_doc_id_to_string docstring's `dimension` parameter.
- Replace the misleading "rewrote 0/N from int to str" wording when
  no rewriting was needed with "N points scanned, none required
  rewriting (collection already in str form)".
- Add test_ensure_keyword_payload_indexes_logs_and_returns_when_
  get_collection_raises mirroring the scroll-failure test.

SonarCloud (1 CRITICAL + 1 MINOR):

- Refactor _backfill_doc_id_to_string to bring cognitive complexity
  under 15 (was 19). Extracted two pure helpers: _group_int_doc_ids
  (group point IDs by stringified doc_id) and _apply_backfill_writes
  (apply set_payload calls and return rewritten count). The main
  function's scroll/loop/sentinel structure is unchanged.
- Add `await asyncio.sleep(0)` to the three async test side_effect
  helpers (_scroll_raises, _upsert_raises, _create_index) so they use
  an actual async feature (S7503). The async-callable shape is still
  required to avoid the AsyncMock unawaited-coroutine warning when
  side_effect raises.

Chris CoutinhoandClaude Opus 4.7 c27556c332 fix(vector): address PR review round 5 — progress logging, summary visibility, sentinel split
Addresses three important findings from the latest reviewer comment:

- Add progress INFO log every 20 scroll batches (≈5120 points at
  batch_size=256) in _backfill_doc_id_to_string so a long-running
  migration on a large collection (50k+ points) doesn't look like a
  startup hang. The line carries collection name, scanned count, and
  rewritten count so it doubles as a heartbeat.
- Track non-400 failures in _ensure_keyword_payload_indexes and emit
  a WARNING summary line listing every field that failed to get an
  index. Per-field ERROR lines are easy to miss in startup noise; the
  summary makes the partial-failure state visible at a glance.
- Split the sentinel upsert out of the data-scroll try/except in
  _backfill_doc_id_to_string. A scroll-time failure still logs ERROR
  with the new "scroll failed" wording (data is incomplete). A
  sentinel-write failure now logs WARNING with "data succeeded but
  sentinel write failed" wording — data is correct, only the
  short-circuit marker is missing, and the next restart re-scrolls
  an already-clean collection (idempotent zero-write) before retrying
  the upsert.

Also fix the RuntimeWarning emitted by
test_backfill_logs_and_returns_when_scroll_raises: replace the bare
`RuntimeError` side_effect with an async-callable side_effect so
AsyncMock awaits the coroutine before the exception propagates.

Three new unit tests cover the new branches:
test_backfill_emits_progress_log_every_20_batches,
test_backfill_logs_warning_when_sentinel_upsert_fails,
test_ensure_keyword_payload_indexes_summarises_failed_fields.

Chris CoutinhoandClaude Opus 4.7 b97ac23228 fix(vector): address PR review round 4 — backfill resilience + degraded-mode docs
- Remove three stale `# Use numeric file ID` / `# Pass file path` comments
  in scanner.py. file_id is already normalized to str() above each call
  site, so the inline comments mislead readers.
- Wrap `_backfill_doc_id_to_string` scroll loop + sentinel upsert in
  try/except Exception. The qdrant_client singleton is assigned before
  this migration runs, so a transient scroll failure was leaving the
  process holding a usable client with int payloads permanently
  unbackfilled until the next restart. Catch broadly, log ERROR with
  exc_info, and return without writing the sentinel — next process
  restart retries from scratch.
- Note `:memory:` mode behavior near the sentinel constants so future
  readers don't read the every-start scroll as a bug.
- Document the two degraded-migration ERROR log signals in
  docs/configuration.md so operators know when a clean restart is
  required to recover indexing.
- Add unit test asserting scroll-time exceptions are logged and swallowed

Chris CoutinhoandClaude Opus 4.7 0b004f54bd refactor(vector): address PR #775 review round 3 — fix unused var, harden boundary lookup, rename trace span
- pdf_highlighter.compute_chunk_bboxes_batch: drop unused chunk_text
  destructure (SonarQube finding), and replace positional
  page_boundaries[page_num - 1] with a key-based next() match so
  reordered or non-1-indexed boundaries can't silently shift the bbox.
  Convert touched f-string log to lazy %s formatting.
- vector/processor: rename the trace_operation span from
  "vector_sync.generate_highlights" to "vector_sync.compute_chunk_bboxes"
  to match what the function actually does.
- Add test_compute_chunk_bboxes_handles_unordered_page_boundaries —
  reverses the boundaries list and asserts identical results to the
  in-order case, guarding the boundary-lookup regression class.
- Pin pre-push-review skill to sonnet model.

Chris CoutinhoandClaude Opus 4.7 92b2d50cd7 fix(vector): address PR review round 3 — sentinel guard, skip indexed fields, narrow types
- Add a fixed-UUID sentinel point written after a successful doc_id
  backfill so subsequent restarts retrieve it and short-circuit the
  O(N) scroll. Sentinel has no user_id/doc_id/doc_type payload so
  production search filters never see it.
- Pre-fetch payload_schema in _ensure_keyword_payload_indexes and
  silently skip fields that are already indexed; the "Created KEYWORD
  payload index" INFO log fires only on actual creation.
- Narrow stale `int | str` doc_id annotations to `str` across
  search/verification.py (BatchVerifier return type, per-verifier
  accessible sets, by_type / accessible_by_type / inaccessible
  collections); drop the now-redundant `type(d).__name__` prefix in
  the dropped-docs log.
- Align the backfill log message with the PR description's
  "Running doc_id backfill" promise; add a caller cross-reference to
  the wait=True comment.
- Fix _get_file_path_from_qdrant docstring (file_id is str, not numeric).
- Convert legacy `id=1` to `id="1"` in test_search_result.py to match
  the SearchResult.id: str annotation.

Three new unit tests cover sentinel-found, sentinel-written, and
skip-existing-index branches; existing backfill tests pass dimension
and explicit retrieve.return_value=[] for the no-sentinel path.

Chris CoutinhoandClaude Opus 4.7 8bc87ed37d refactor(vector): address PR #775 review round 2 — drop dead page field, add omission tests
- chunk_bboxes is now dict[int, list[tuple[...]]] holding the bbox list
  directly, not {"bbox": ..., "page": ...}. The page from text-search was
  stored but never read; page_number from offset-based assignment is
  authoritative for the Qdrant payload.
- Add two unit tests for the documented omission contract: chunks whose
  offsets fall outside every page boundary, and chunks whose text cannot
  be located on the rendered page, are silently dropped from the result.

Chris CoutinhoandClaude Opus 4.7 b5b4025bb4 fix(vector): address PR review round 2 — status branching, doc_id guard, doc restore
- _ensure_keyword_payload_indexes: distinguish 400 (schema conflict, warning)
  from other status codes (5xx/network, error) so a transient outage doesn't
  silently leave the collection unindexed.
- build_search_result_from_point: use .get("doc_id") + return None on missing
  instead of KeyError-crashing the search; reverse metadata merge order so
  payload-derived chunk_index/total_chunks win over caller-supplied extras.
- docs/configuration.md: restore the OpenAI/Mistral/Bedrock/Simple provider
  sections + reference-table rows that were dropped in the rebase. Reword
  the "Startup migrations" bullet to describe what the code actually does
  (no sampling — full scroll, zero writes when clean). Add operator note
  about the SemanticSearchResult.id TypeError path.
- tests: pytest.approx for float equality (Sonar python:S1244); coverage
  for non-400 → ERROR, payload={doc_id: None}, and missing doc_id key.

Chris CoutinhoandClaude Opus 4.7 80b27b1bc6 refactor(vector): address PR #775 review — drop unused payload key, fix resource leaks
- Drop chunk_bbox_page from Qdrant payload — viz endpoints never read it

- Bump upsert BATCH_SIZE 10 → 100 now that payloads no longer carry PNGs.
- compute_chunk_bboxes_batch: move doc.close() into finally, replace
  unused stored_page_num with _.
- purge_page_images.py: switch to anyio.run() per project convention,
  and wrap AsyncQdrantClient in try/finally so the aiohttp session is
  always closed (the class doesn't implement async-context-manager).
- Decorate new bbox unit tests with @pytest.mark.unit so they run under
  the fast-feedback selector.

Chris CoutinhoandClaude Opus 4.7 ee402ea00e feat(vector): replace inline page-image payloads with chunk_bbox (Deck #76)
Per-chunk PDF page renders (~150–700 KB base64 PNG each) were the dominant
disk consumer in production, repeatedly tripping `No space left on device:
WAL buffer size exceeds available disk space` on welcomed-malamute Qdrant.

Replace the inline highlighted_page_image / highlighted_page_number /
highlight_count fields with a small `chunk_bbox` field:
list[(x0, y0, x1, y1)] of normalized [0, 1] floats, ~32 bytes per chunk.
Astrolabe (the only known consumer) renders the highlight client-side as
a percentage-positioned overlay on top of the existing /api/v1/pdf-preview
render-on-demand path (cbcoutinho/astrolabe#76).

- pdf_highlighter: new compute_chunk_bboxes_batch() that reuses the
  existing _find_chunk_bbox text-search path, skipping all pixmap/PIL/PNG
  work.
- processor: store chunk_bbox + chunk_bbox_page in the Qdrant payload,
  drop highlighted_page_image + friends, drop the base64 import.
- visualization /api/v1/chunk-context and auth/viz_routes: read
  chunk_bbox instead of highlighted_page_image.
- vector/__init__: stop eagerly re-exporting `processor`/`scanner` —
  fixes a pre-existing circular import (search.algorithms ->
  vector.placeholder -> vector/__init__ -> processor -> scanner ->
  server.semantic -> search.bm25_hybrid -> search.algorithms partial).
  Test suite that was broken on master (test_bm25_hybrid.py et al.) now
  collects and passes.
- scripts/purge_page_images.py: ad-hoc, idempotent migration that
  delete_payload's the legacy keys from existing points. No reindex
  required; legacy chunks render the page with no overlay.

Pairs with cbcoutinho/astrolabe#76. Frontend handles missing chunk_bbox
gracefully, so this can land in either order.

Chris CoutinhoandClaude Opus 4.7 6aba589a6e fix(vector): address PR review — wait=True backfill, batched writes, search helper
Addresses reviewer feedback on PR #773:

- Backfill set_payload now uses wait=True to avoid a race where
  _ensure_keyword_payload_indexes builds the KEYWORD index before
  fire-and-forget writes have committed, leaving int payloads
  invisible to filters.
- Batch points sharing the same int doc_id into a single set_payload
  call (one document → many chunks → one round-trip instead of N).
- Drop _has_int_doc_id_sample short-circuit. The sample's false-negative
  window (clean first 256 results, ints further in) is gone; full scroll
  is the dominant cost on first run anyway.
- Simplify _ensure_keyword_payload_indexes: the "already exists" 400
  branch was dead code (Qdrant returns 200 on identical re-create); any
  400 now logs a warning and continues.
- search/context.py: comment the broadened file-type guard. Add explicit
  not doc_id.isdigit() checks at the top of note/news_item/deck_card
  branches in _fetch_document_text so malformed payloads surface as
  warnings instead of being swallowed by the broad except.

Also extracts build_search_result_from_point into search/algorithms.py
to deduplicate the 71-line payload-extraction loop shared by
SemanticSearchAlgorithm and BM25HybridSearchAlgorithm. This fixes
SonarQube's quality-gate failure (4.0% new-code duplication, max 3%).

Test coverage:
- 7 new unit tests for build_search_result_from_point covering missing
  payload, note/file/deck_card metadata, int doc_id coercion, and
  metadata_extras merging.
- Replace _has_int_doc_id_sample tests with clean-collection no-op and
  per-batch grouping tests.
- Update set_payload assertions from wait=False to wait=True.

Chris CoutinhoandClaude Opus 4.7 719b3b5034 fix(vector): normalize doc_id to str + add Qdrant keyword payload indexes
Production was logging two cascading classes of Qdrant errors against the
welcomed-malamute deployment:

1. HTTP 400 — "Bad request: Index required but not found for \"doc_id\" of
   one of the following types: [keyword]". The collection was created via
   create_collection() with no payload indexes, so any FieldCondition
   filter on doc_id failed at the Qdrant layer (placeholder writes/reads,
   eviction, search context lookups).

2. Compounding the missing index, producers wrote a mix of int and str
   doc_ids: webhook_parser stringified node_id, scanner stringified note
   IDs, news IDs, and deck card IDs — but the file scanner passed the
   numeric file_id through unchanged. A keyword index would not have
   covered both kinds even if it had existed.

This change:

- Normalizes doc_id to str at every producer site (scanner.py:459,
  DocumentTask.doc_id, indexed_*_ids reads from Qdrant).
- Tightens str|int annotations to str across placeholder.py,
  eviction.py, search/verification.py, search/context.py,
  SearchResult.id, and the auth/api visualization endpoints.
- Defensive str() coercion on doc_id reads in semantic.py /
  bm25_hybrid.py / vector/visualization.py for the transition window
  before the backfill runs.
- Adds an idempotent startup migration in get_qdrant_client():
  - _ensure_keyword_payload_indexes creates KEYWORD indexes for
    doc_id, user_id, and doc_type (tolerates "already exists" 400s).
  - _backfill_doc_id_to_string scrolls the collection once and rewrites
    int doc_ids to str. Skipped after a quick sample shows no legacy
    int payloads.
- Public API preserved: SemanticSearchResult.id stays int via explicit
  int(r.id) narrowing in server/semantic.py — surfaces a TypeError with
  actionable context if a future doc_type ships non-numeric ids.
- Documents the startup migration in docs/configuration.md.

Tests: 11 new unit tests in tests/unit/vector/test_qdrant_client.py
covering happy path / already-exists / unrelated-400 for the index
helpers, and sample-skip / mixed-batch rewrite / payload=None edge cases
for the backfill. 889 unit tests pass.

Chris CoutinhoandClaude Opus 4.7 43c6788555 feat(vector): expand tagged directories for include + apply EXCLUDED_TAGS in scanner
NextcloudClient.find_files_by_tag now mirrors the directory semantics
already used by the exclusion path (issue #710): when a tagged item is
a folder, walk its descendants via WebDAV SEARCH (Depth: infinity) and
include any files matching the MIME filter. Without this, tagging the
root of a corpus with `vector-index` indexed nothing because the tag
applies to the directory only, not to its children.

The vector scanner additionally consults EXCLUDED_TAGS now, so a folder
marked off-limits is skipped even if it (or an ancestor) carries the
include tag — defense-in-depth, matching the "exclusion wins" contract
already enforced by the MCP file tools.

Also addressed a recurring memory-style nit: pre-existing f-string log
lines in find_files_by_tag were converted to lazy %-style.

Chris CoutinhoandClaude Opus 4.7 e8df6003c5 refactor(search): address PR #750 round 6 review feedback
Closes out the remaining nits flagged in the round-6 review.

Critical:
- _verify_files contract comment now enumerates all None-return cases
  (404 + malformed PROPFIND XML) and documents the false-eviction
  trade-off; self-healing via re-indexing recovers
- int(r.id) cast at the SemanticSearchResult boundary now raises a
  TypeError with explicit doc_type/value context instead of bubbling
  up as an opaque "Search failed: ..." McpError

Design observations:
- nc_semantic_search_answer docstring documents the per-note
  round-trip cost from the post-verification race guard
- News verification latency hint added to configuration.md
- SemanticSearchResponse exposes verified_count + dropped_count so
  short result pages on high-ghost-density indexes are
  distinguishable from genuine scarcity. verify_search_results now
  returns (kept, dropped_count); production caller and tests updated

Minor:
- Comment clarifies the .get() fallback in verify_search_results is
  defensive only (run_verifier always populates the entry)
- Eviction task-group guard narrowed from except Exception to
  except RuntimeError (the only documented failure mode of
  TaskGroup.start_soon on a closed group)
- Indexer logs a warning when a deck_card task is missing
  board_id/stack_id, surfacing data-quality issues at index time
  rather than at verification time
- New unit test covers the news verifier's non-numeric-id fail-open
  path (one bad doc_id keeps the entire batch)

Chris CoutinhoandClaude Opus 4.7 21e5608a39 refactor(search): address PR #750 round 2 review feedback
Implements fire-and-forget eviction (ADR-019 §"Lazy eviction"): the
search response no longer waits on Qdrant deletes, instead spawning
evict() on a long-lived lifespan-owned task group. Falls back to inline
eviction in modes without vector sync and in unit tests.

Also: harden _verify_news_items against non-numeric ids (fail open
instead of crashing the verifier); document the get_file_info None-on-404
contract; add INDEXED_DOC_TYPES single source of truth in vector/scanner.py
referenced by the CI-guard test; write a Verify-on-Read Latency Budget
section in docs/configuration.md covering the unbounded news.get_items
fetch. Closes the two remaining ADR-019 implementation checklist items.

Chris CoutinhoandClaude Opus 4.7 d90e793d19 feat(search): verify-on-read for semantic search results (ADR-019)
The vector index lags Nextcloud (5-min webhook cron + scanner interval),
producing ghost records for deleted/unshared documents until the next
reconciliation. Verify each unique document against Nextcloud at query
time, drop inaccessible results, and lazily evict the corresponding
Qdrant points.

Per-doc_type batch verifiers: notes/files/deck cards run concurrently
per id; news items use a single fetch + intersect to avoid the per-item
fetch-all amplification. Transient errors fail open (keep result, log
warning) — only definitive 4xx drops. Multiple chunks of the same doc
collapse to one verification call.

Wired into nc_semantic_search before the limit trim and before context
expansion. nc_semantic_search_answer's per-note re-fetch retained as a
sub-second race guard since verification now happens upstream.
