Chris CoutinhoandClaude Opus 4.8 f6ab04b2d9 docs: add ADR-027 for rich search filters
Add ADR-027 describing rich, chip-style filters for Astrolabe semantic
search (modified-date range, doc type, path, tags). Generalises the
existing doc_type filter contract (tool param -> search() kwarg ->
Qdrant FieldCondition applied pre-fusion and pre-verify-on-read) and
phases the rollout by payload readiness: date range ships now, path and
tags defer behind a payload index / re-index.

Tracking: Astrolabe Cloud POC Deck card #177

Chris CoutinhoandClaude Opus 4.8 d2da195172 refactor(deck): address PR #826 review feedback
- Modernize the new models (DeckCardSummary, DeckCommentSummary,
  StackOverview, BoardOverviewResponse + the loosened unions) to PEP 604
  syntax (list[...] / X | None), per CLAUDE.md.
- Make status="done" exclude archived cards so open/done/archived partition
  the board with no overlap (a done+archived card is reported only as
  "archived"); document the semantics in docstrings and docs/deck.md, add a
  partition unit test.
- deck_get_archived_stacks: pass through label/assigned_to filters (status
  stays archived-only by definition); note the limitation in the docstring.
- Rename _validate_description_max_length → _validate_positive_length (now a
  generic positive-length guard).
- Soften deck_get_board_overview docstring: it views board state and omits
  the ACL/user/label-management fields deck_get_board exposes.

Chris CoutinhoandClaude Opus 4.8 4f170d32cb fix(embedding): normalize gateway base_url to the /v1 base path
EMBEDDING_GATEWAY_URL is configured as a bare origin (scheme://host:port) —
the deployment's Service URL. GatewayProvider now appends the gateway's /v1
base path before handing the URL to the OpenAI SDK, so both embed posts
({base}/embeddings) and dimension discovery ({base}/models) land under /v1.
Idempotent: a URL already ending in /v1 is left unchanged.

This lets EMBEDDING_GATEWAY_URL stay a bare domain (matching the gitops
Service URLs) instead of requiring a hand-appended /v1.

Also align the `embedding_gateway_model` field default with _DEFAULTS
("mistral/mistral-embed"). The gateway catalog is provider-namespaced, and
_detect_dimension matches `entry.id == embedding_model`; the stale
un-namespaced default would silently miss the catalog entry and leave the
dimension unresolved (re-triggering the external-mode startup crash).

Tests: bare / trailing-slash / idempotent normalization + a bare-origin
discovery test asserting /v1/models. 16 gateway-provider tests pass;
providers + vector suites green (129 total); ruff clean.

Chris CoutinhoandClaude Opus 4.8 b11103064c feat(deck): compact card/comment retrieval (summaries, filters, board overview)
Deck read tools returned too many tokens to be usable as boards grow — even
deck_get_stacks(description_max_length=1) exceeded the MCP token limit because
every card was fully serialized in list views.

- Add compact projection models (DeckCardSummary, DeckCommentSummary,
  StackOverview, BoardOverviewResponse) and a uniform detail="summary"|"full"
  knob (summary default) on deck_get_cards / get_stacks / get_stack /
  get_archived_stacks.
- Add pre-serialization filtering: status (open/done/archived/all), label,
  assigned_to.
- Add deck_get_board_overview: board title + label legend + stacks with
  compact card rows + counts in a single call.
- Compact comments: detail / message_max_length / newest-first order on
  deck_get_card_comments.
- Docs + unit/integration tests.

BREAKING CHANGE: deck list tools now default to detail="summary" and
status="open". The include_archived_cards parameter is replaced by status
(use status="all" to include archived cards); pass detail="full" to restore
the previous per-card shape.

Chris CoutinhoandClaude Opus 4.8 be360edab0 fix(api): distinguish Nextcloud 5xx from auth failure; tighten body parse (#824)
Address PR #825 review round 2:
- _validate_nextcloud_credentials now only maps OCS HTTP 401/403 to a 401
  "invalid credential"; any other non-200 (5xx, 503 maintenance mode) surfaces
  as 502 "Nextcloud returned a server error" so ops don't chase a phantom bad
  password when Nextcloud is actually down.
- The client-facing 401 message is now a parameter, so delete_app_password keeps
  its "Invalid credentials" wording without unwrapping/rebuilding the helper's
  JSONResponse.
- Body parsing catches (ValueError, UnicodeDecodeError) instead of bare
  Exception, and guards body.get behind isinstance(body, dict) — no longer
  swallows RuntimeError/AttributeError or a non-object JSON body.
- Add a unit test asserting 500/503 -> 502.

Chris CoutinhoandClaude Opus 4.8 3c55d03ecf fix(api): block cross-user delete and address review feedback (#824)
Review of PR #825 surfaced an auth bypass introduced by adding loginName
support to delete_app_password: with the OCS-resolved UID discarded, a user
could authenticate as their own loginName (via the request body) while
targeting another user's path and delete the victim's stored app password.
Add the same UID-mismatch guard provisioning already has, so the
authenticated account must own the path UID (403 otherwise).

Also:
- integration test: build the BasicAuth header via base64 instead of
  httpx.BasicAuth._auth_header (private attribute); mark the throwaway test
  credential NOSONAR(S2068).
- unit tests: cover the httpx.RequestError -> 502 branch, the standard OCS v2
  success shape (meta.statuscode 200), and the cross-user delete 403 guard.

Chris CoutinhoandClaude Opus 4.8 a11a4e709c fix(api): return 401 not 500 on failed app-password OCS validation (#824)
provision_app_password validated credentials against OCS v1
(/ocs/v1.php/cloud/user), which always returns HTTP 200 — even on auth
failure, where the real status lives in ocs.meta.statuscode (997) and
ocs.data comes back as an empty list []. The status_code != 200 guard
therefore never fired, execution fell through to [].get("id"), and the
resulting AttributeError escaped as an unhandled 500. This blocked
background vector indexing for any user whose supplied loginName didn't
resolve (e.g. display name "Admin" vs loginName "admin").

Extract a shared _validate_nextcloud_credentials helper that:
- queries OCS v2 (/ocs/v2.php), which maps the OCS status onto the HTTP
  status, so a failed credential is a real 401;
- parses the payload defensively (isinstance guards) so a non-dict
  ocs.data can never raise;
- returns a clean 502 for an unreachable Nextcloud or a non-JSON body.

delete_app_password shared the same v1.php dead-guard bug, which made its
credential check a no-op (any valid-format password passed) — an auth
bypass on deletion. Route it through the same helper and accept the
loginName from the request body (mirroring provisioning) so OIDC users
whose UID differs from their loginName are not regressed.

Adds unit regression tests for the OCS failure payload, non-dict data,
and non-JSON response, plus a login-flow integration test that provisions
with capitalized ("Admin") and spaced ("Test User") loginNames and asserts
a 401 rather than a 500.

Chris Coutinho d84a95842f feat(embedding): gateway provider discovers dimension via GET /v1/models
External-mode tenant pods CrashLoop at startup: Qdrant collection init calls
get_dimension() before any embed(), but GatewayProvider only learns its
dimension lazily after the first embed, and the gateway model isn't an OpenAI
model so the base class can't know it statically.

- Add GatewayProvider._detect_dimension() — the async startup hook the
  vector-sync bootstrap already invokes (vector/qdrant_client.py:
  hasattr(provider, "_detect_dimension")) for Ollama. It GETs the gateway's
  GET /v1/models and sets _dimension from the entry whose id matches the
  configured model. Best-effort: any failure (old gateway, model absent,
  network) leaves _dimension unset so the inherited lazy detect-on-first-embed
  still applies — never fatal. Presents the M2M bearer when configured.
- Switch the default embedding_gateway_model to the gateway's provider-
  namespaced id "mistral/mistral-embed" (the gateway routes on the "/"-prefix
  and sends "mistral-embed" upstream); collapse a duplicated config field.

Pairs with astrolabe-cloud-website#229 (gateway /v1/models, namespaced ids).

Tests: discovery sets dim w/o embed, sends bearer, non-fatal on
404/absent/error, skips when already known.

Chris CoutinhoandClaude Opus 4.8 cd2145df09 fix(vector): make NATS status subscriber resilient at startup
Follow-up to PR #814 review.

NatsStatusSubscriber.run() called task_status.started() *after* the fallible
pull_subscribe, so a NATS broker that wasn't ready when the MCP server started
would crash the lifespan instead of retrying. Bus status is a non-critical
observability path, so:

- signal started() before the first subscribe (semantics: "loop is running",
  not "subscription succeeded");
- retry a failed subscribe with backoff instead of propagating;
- on a real fetch error (not an idle timeout) drop the subscription and
  re-subscribe rather than fetching against a possibly-dead handle.

Also anchor the _content_hash etag-threading TODO to the PR #814 review thread
so it is discoverable outside git blame.

Chris CoutinhoandClaude Opus 4.8 52da297ded fix(auth): authenticate stored app passwords with loginName, not UID
Nextcloud authenticates app passwords against the *loginName*, which differs
from the UID for OIDC-provisioned users (e.g. user_oidc makes the UID the
display name: UID "Ada Lovelace", loginName "ada@example.com"). The runtime
consumers of stored app passwords bound the UID as the BasicAuth username, so
every Notes/Files/Shares/CalDAV call returned HTTP 401.

PR #818 fixed only the provisioning endpoint; the consuming paths were missed.
Observed on a login_flow tenant (NC's own OIDC app as IdP): the background-sync
scan loop never started ("Credential validation failed ... HTTP 401") and
semantic search returned 0 results because the ACL shared_with_me lookup 401'd
and degraded to a self-only owner filter.

Root cause: NextcloudClient / CalendarClient conflated two identities — the
DAV/URL path identity (the user_id the whole system keys on = NC UID) and the
auth-credential username (the loginName). Decouple them:

- Thread a keyword-only auth_username through NextcloudClient -> CalendarClient
  (defaults to username, so single-user / OAuth where UID == loginName is
  unchanged).
- get_user_client_basic_auth (background sync + the /api/v1/vector-viz/search
  endpoint) authenticates as the stored loginName, UID for paths.
- _get_client_from_login_flow (the get_client(ctx) MCP-tool path) does the same.
- cleanup_invalid_app_passwords validates with the loginName, so it no longer
  401s and wrongly deletes a valid OIDC user's password.

The loginName is already persisted in app_passwords.username and returned by
get_app_password_with_scopes. Adds unit tests covering the UID != loginName
split for both client builders, the calendar credential/path split, and the
cleanup validation. Also genericises the example user in the #818 comment/test
(real name/email -> Ada Lovelace / ada@example.com).

Chris CoutinhoandClaude Opus 4.8 fdc0bdeae4 test(astrolabe): install app from Nextcloud app store; bump submodule to v0.16.6
Stop mounting the vendored astrolabe submodule into the Nextcloud `app`
container by default (comment out the /opt/apps/astrolabe bind mount). With
the mount absent, the post-installation hook (20-install-astrolabe-app.sh)
falls through to `occ app:install astrolabe` + `app:enable`, so the dev/CI
stack now exercises the published app-store package rather than a locally
built dev copy. This catches packaging issues (e.g. missing built assets in
the released app) that a source build would mask.

Bump the third_party/astrolabe submodule to v0.16.6, which includes the
background-indexing re-login fix (astrolabe#93).

The dev mount and the CI "Build Astrolabe app" step are retained (commented
mount can be re-enabled locally) so developers can still iterate against the
vendored source on demand.

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 0df3fb4a19 fix(api): validate app password against Nextcloud using loginName, not UID
provision_app_password validated the supplied app password by calling the
OCS cloud/user endpoint with BasicAuth as the *path user_id* (the UID).
Nextcloud keys app-password BasicAuth on the loginName, which differs from
the UID for OIDC-provisioned accounts whose UID is their display name
(UID "Chris Coutinho", loginName "chris@coutinho.io"). Authenticating as
the UID is rejected with HTTP 401 ("App password validation failed"), so
provisioning never completes.

Parse the request body up front and authenticate the OCS validation as the
body's `username` (the Nextcloud loginName), falling back to the path
user_id for legacy callers where UID == loginName. The OCS-returned account
id is still checked against the path user_id (the UID), and the password is
still stored keyed by UID with the loginName alongside.

Note this is not an encoding issue: BasicAuth places the user-id literally
in the header (RFC 7617, no URL-encoding); %20/+/literal-space forms of the
UID all fail — only the loginName authenticates.

Adds a regression test asserting the OCS BasicAuth uses the loginName while
storage is keyed by the UID, plus a backward-compat assertion that callers
without a loginName fall back to the UID.

Chris CoutinhoandClaude Opus 4.8 29500bea7e fix: PR #813 review — cap unified_search multi-type pool; document deck self-only
🟡 Performance: unified_search's _execute sorted but did not cap the merged
multi-doc_type pool, so N doc_types each fetched at search_limit sent
N*search_limit candidates into verify-on-read (one Nextcloud round-trip each).
Cap to search_limit*2 after the sort, matching vector_search, nc_semantic_search
and the viz_routes pattern — bounding verification cost to O(2*search_limit)
regardless of how many doc_types are requested.

🟡 Consistency: _get_deck_metadata_from_qdrant is the one internal Qdrant lookup
that uses a raw user_id filter instead of build_ownership_filter. This is not a
bug — deck cards are a documented cross-user gap (the Deck API is per-user, so
cross-user context can't be fetched with the caller's credentials) — but the
inconsistency was unexplained. Added a comment documenting the deliberate
self-only scope.

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 350358b802 fix: PR #813 review — shared-file context in MCP tool path + viz over-fetch cap
🟡 Important: nc_semantic_search's include_context branch did not forward
accessible_owners to get_chunk_with_context, so context expansion for shared
files stayed self-only, found nothing in Qdrant, and silently fell back to the
plain excerpt. Forward accessible_owners (the per-file file_accessible_by_id
gate still enforces access).

🟡 Performance: auth/viz_routes.py's multi-doc_type branch sorted but did not
cap the candidate pool before verify-on-read, so N doc_types × limit*2 went
into verification (N× the Nextcloud round-trips). Cap to limit*2 after the
sort, matching server/semantic.py and the cross-app branch.

Also clear the SonarCloud gate (new_duplicated_lines_density 5.1% > 3%) the
ACL wiring introduced: extract the duplicated /api/v1 client-resolution +
owner-expansion + verify-on-read block from unified_search/vector_search into a
shared _search_with_acl helper, define a constant for the repeated
"Nextcloud host not configured" literal (S1192), and reword the access_filter
move_to_end comment so it isn't misread as commented-out code (S125) while
adding the other-owner count to its debug log (review nits).

Chris CoutinhoandClaude Opus 4.8 8deb48e6fa fix: address PR #813 review round 4 (log leak, cross-user chunk ctx, algo, overlap)
1. Don't log unverified result titles: both search algorithms logged top-5
   titles at DEBUG before verify-on-read; with owner-level share expansion the
   unverified set can contain other users' docs. Algorithms now log a count
   only; the verifying callers (server/semantic, viz_routes, api/visualization)
   log verified titles after verify-on-read.

2. Cross-user FILE chunk context: get_chunk_with_context + the Qdrant chunk
   helpers now take accessible_owners and use build_ownership_filter. For files
   the expanded scope is honoured only after a per-file file_accessible_by_id
   check (accessible_owners is owner-level, so the gate prevents a one-file
   share recipient from reading any of the owner's cached chunks). note/deck/
   news stay self-only (per-user APIs) — a documented gap. Both chunk endpoints
   pass accessible_owners.

3. Algorithm usage: SemanticSearchAlgorithm is not dead (it backs the dense-only
   option on the viz/API surfaces); added a clarifying comment in server/
   semantic.py. Additionally wired accessible_owners + verify-on-read into the
   /api/v1 search routes (unified_search, vector_search) so the astrolabe
   surface is ACL-aware too — degrading gracefully to self-only/unverified for
   non-provisioned callers instead of 401.

4. Overlapping conditions: build_ownership_filter no longer lists self in the
   owner_id MatchAny branch (self is already covered by the user_id branch);
   the owner_id branch carries only the OTHER owners.

Tests: build_ownership_filter dedup + chunk-bbox filter-shape updates; new
ACL-aware get_indexed_doc_types, cached-chunk lookup, and end-to-end cross-user
file chunk-context (recipient gets the chunk, non-recipient denied) tests.

  ("absent, not empty") to avoid skipping on a falsy-but-present field.
- access_filter: add an operator note that pre-owner_id points need a re-index
  to surface to share recipients (ACL search is a no-op for legacy data).
- verification/webdav: lock the file_accessible_by_id(scope="") contract with a

Chris CoutinhoandClaude Opus 4.8 531228d407 chore: bump astrolabe submodule (cleartext-transport warn, not block)
Fixes the multi-user-basic regression introduced by the previous bump: the
astrolabe app's hard https-refusal blocked sending the app password to the
in-cluster http MCP endpoint (http://mcp-multi-user-basic:8000), so background
indexing never ran. Now warns instead of blocking; also clears the SonarCloud
S5332 hotspot on the dropped test's http literal.

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).

- viz_routes: run verify_search_results before returning results. After the
  accessible_owners expansion the viz can surface OTHER users' shared docs, so
  it must drop ones the caller can no longer access (revoked share) — same as
  the nc_semantic_search tool path. (Blocking review item.)
- access_filter: cache list_accessible_owners per user for 30s to keep the OCS
  shares round-trip off the search hot path (failures aren't cached); document
  the single-page OCS limitation; add a clear_accessible_owners_cache() test
  helper. Comment the empty-accessible_owners MatchAny([]) edge case.
- verification: comment why cross-user eviction is a deliberate no-op (eviction
  is scoped to the querying user's id, so a recipient's revoked access never
  deletes the owner's points; the recipient self-heals via accessible_owners).
- algorithms: declare SearchResult.original_score (set by the viz route) so the
  now-precisely-typed result list type-checks.
- tests: cross-user eviction-no-op safety test; autouse owners-cache reset in
  the access_filter + shared-search tests; replace async-no-await qdrant fakes
  with AsyncMock (clears SonarCloud S7503).

Chris CoutinhoandClaude Opus 4.8 d9a716080a fix(auth): make provision/revoke consistent with the app-password store
The OAuth provisioning tools (check_provisioning_status, revoke_nextcloud_
access) only consulted the refresh-token store + Astrolabe status, ignoring the
app_passwords store that Login Flow v2 (nc_auth_provision_access) and the
management API write to — the same store require_provisioning / get_client use
to grant tool access. Result: status reported "not provisioned" while tools
worked, and revoke said "nothing to revoke" while the credential persisted.

- _get_provisioning_status: also check storage.get_app_password_with_scopes,
  reporting is_provisioned with credential_type=app_password,
  flow_type=login_flow_v2.
- _revoke_nextcloud_access: when the credential is an app password, delete it
  from storage + invalidate the scope cache (no IdP token to revoke);
  refresh-token revocation via the Token Broker is unchanged.
- tests/unit/test_oauth_tools_app_password_provisioning.py: cover status +
  revoke for the app-password path.
- bump astrolabe submodule (deprovision MCP on disable); fix a stale assertion
  in the migrated bg-sync test (one-click flow has no separate app-password
  generation step).

Astrolabe was refactored to mint session-derived JWTs (TokenGenerationRequest
Event) and a one-click background-indexing opt-in, dropping the OAuth
authorize/callback/refresh surface. Bump the submodule and bring the test
suite in line:

- New test_astrolabe_session_jwt_search.py: a logged-in user searches via the

  OAuth-authorize test; token_refresh test deleted — refresh flow is gone).
- settings_buttons: assert the new revoke endpoint + that oauth/disconnect is
  gone (404).
- multi_user_background_sync / plotly / chunk_context: drop the OAuth authorize
  step; provision via the one-click "Enable background indexing" button
  (#mcp-enable-background-button -> #mcp-revoke-background-button) instead of
  generating + pasting an app password.
- docker-compose.yml: mount the astrolabe submodule into the app container.
- third_party/astrolabe: bump to the one-click opt-in commit.

Chris CoutinhoandClaude Opus 4.8 ae54956f27 fix(auth): login-flow provisioning — public login_url + session app passwords
Two fixes surfaced while testing Login Flow v2 provisioning behind a split
internal/external host (Docker: server↔Nextcloud over http://app, browser
over http://localhost:8080):

1. login_url pointed at the internal host. Nextcloud builds the login URL
   from the request host, so the browser-facing URL came back as
   http://app/login/v2/flow/... — unreachable from the user's browser. The
   poll endpoint was already rewritten to the internal host (correct, the
   server polls it); now LoginFlowV2Client also rewrites the login_url origin
   to settings.nextcloud_public_issuer_url when set (passed at all 5
   construction sites). When unset, behaviour is unchanged.

2. The app-password format guard rejected raw session tokens. core/
   getapppassword returns a long alphanumeric token, not the dashed 25-char
   Security-settings format, so the dashed-only regex 400'd the one-click
   opt-in handoff. Relax APP_PASSWORD_PATTERN to `^[a-zA-Z0-9-]{20,256}$`;
   the authoritative validation is still the BasicAuth check against Nextcloud.

Chris CoutinhoandClaude Opus 4.8 bf35200bab fix(search): verify shared files by global file id (ACL-aware)
The ACL-aware vector filter (PR #813) expands a user's search to documents
whose owner shared them, but verify-on-read still re-checked each file by
PATH under the *searching* user's WebDAV root. Nextcloud mounts received
shares at the recipient's root by basename, so a nested shared file (e.g.
owner's /docs/report.pdf) 404s for the recipient and was silently dropped —
defeating the filter for everything but root-level files.

Verify files by their global Nextcloud file id instead (the file doc_id IS
that id): WebDAVClient.get_file_info_by_id was insufficient (the dav/meta
endpoint only resolves the user's own storage, not shares), so add
WebDAVClient.file_accessible_by_id which runs a WebDAV SEARCH over the user's
whole tree (incl. mounted shares) filtered on oc:fileid. Empirically this
resolves owned, directly-shared, and folder-shared files; an empty result is
a definitive drop, transport errors are kept as transient.

- search/verification.py: _verify_files now checks file_accessible_by_id.
- client/webdav.py: add file_accessible_by_id (SEARCH by fileid).
- tests/integration/test_acl_owner_filter.py: filter matrix vs real Qdrant.
- tests/integration/test_acl_shared_search.py: real-Nextcloud share -> search.
- tests/integration/test_verify_on_read.py: nested shared file kept for the
  recipient; unshared file dropped.
- tests/unit/search/test_verification.py: id-based verifier semantics.

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.

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 688a03f00a fix(contacts): surface ORG/TITLE/NOTE/URL/CATEGORIES/PHOTO on read (refs #716)
PR #719 fixed the contact-create path so all documented fields persist to the
vCard, but the read path (list/search via MCP) still returned ``organization:
null`` / ``note: null`` / ``title: null`` because pythonvCard4 has no typed
parser for ORG/TITLE — they land in ``Contact.custom`` — and the server-side
mapper never read ``note``/``urls``/``categories``/``photo`` even when present.

Reads now surface what the write side persisted:

- ``client/contacts.py``: new ``_first_custom`` helper pulls raw values from
  ``Contact.custom`` for ORG/TITLE/unencoded PHOTO. ``list_contacts``
  extends its per-contact dict with org/title/note/url/categories/photo.
- ``server/contacts.py``: ``_raw_contact_to_model`` maps the new keys onto
  ``Contact.organization`` / ``.title`` / ``.note`` / ``.urls`` / ``.categories``
  / ``.photo``. URL accepts both list and plain-string shapes; categories
  accepts comma-separated strings for forward-compat.

Coverage:

- Unit: ``TestFirstCustom`` (five cases incl. bare-string library shape) and
  three new ``_raw_contact_to_model`` cases covering the full field set,
  plain-string URL, and comma-string categories.
- Integration: ``test_mcp_contacts_workflow`` now decodes the
  ``nc_contacts_search_contacts`` response and asserts
  ``organization`` / ``note`` round-trip — direct regression coverage for
  elvisdragonmao's report on issue #716.

Verified end-to-end against the local single-user docker stack: creating a
contact with ``{organization, title, note, url, categories}`` and reading it
back via ``nc_contacts_search_contacts`` returns every field populated.

Chris CoutinhoandClaude Opus 4.7 7da72a3888 feat(api): log inbound User-Agent on management API and webhook receiver
Astrolabe (and any other PHP-side client) sends a stable User-Agent on
every outbound call to the MCP server. Capture it at the middleware
layer so backend access logs can attribute each request to a specific
client build — e.g. ``Nextcloud-Astrolabe/0.14.1``.

The middleware fires only for /api/v1/* and /webhooks/nextcloud,
which is the surface PHP-side clients hit; /mcp and /health stay
silent. The structured ``extra`` ({user_agent, http_method, http_path})
flows into OTel spans so the field is queryable in Grafana / Loki.

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 a0b29a436e feat(ci): build arm64 Docker images natively on ubuntu-24.04-arm
Split the Docker image build into a per-platform matrix and merge job,
producing a single multi-arch manifest (linux/amd64 + linux/arm64) without
QEMU emulation. The arm64 build runs on the native ubuntu-24.04-arm runner.

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 ruff check`` clean on touched files
- ``uv run ty check`` clean on touched files

Chris CoutinhoandClaude Opus 4.7 e98903c502 fix(storage): address review on PR #799 (stale comments, docs deprecation, unit test)
claude-review on #799 flagged:

1. Stale inline comment in ``initialize()`` (line 466) still said
   "Postgres uses a small bounded pool". Updated to reflect both
   backends now use NullPool.

2. Stale ``close()`` docstring referenced pool-size starving
   max_connections — irrelevant with NullPool. Replaced with the
   NullPool-aware rationale (dispose still tears down in-flight
   asyncpg connections cleanly).

3. ``docs/configuration.md`` actively directed operators to tune
   DATABASE_POOL_SIZE / DATABASE_MAX_OVERFLOW, with worked
   examples and pool math. Both are now deprecated no-ops; the
   table entries explain the deprecation and link to PR #799.
   Operators reading the docs will no longer be confused into
   tuning settings that don't do anything.

4. ``config.py`` comment for the deprecated fields updated to
   record the deprecation. Validators are intentionally kept
   (still reject < 1 / < 0) so misconfigured deploys fail loudly
   rather than silently — the reviewer flagged this as a minor
   UX wart but explicitly "not a blocker"; the docs change in (3)
   keeps operators away from the config altogether.

5. New ``tests/unit/test_storage_engine.py`` with three tests:
   - ``test_postgres_engine_uses_nullpool`` — pins ``isinstance(
     engine.pool, NullPool)`` so a refactor back to QueuePool /
     SingletonThreadPool can't silently re-introduce the cross-
     event-loop crashes.
   - ``test_postgres_engine_ignores_pool_sizing_settings`` —
     setting DATABASE_POOL_SIZE / DATABASE_MAX_OVERFLOW to huge
     values must not change pool type (proves the deprecated
     fields are wired-up no-ops).
   - ``test_postgres_engine_missing_asyncpg_driver_message`` —
     guards the existing actionable-error branch when the
     optional ``[postgres]`` extra isn't installed.

Verified:
- ``uv run pytest tests/unit/`` — 1028 passed
- ``uv run ruff check`` clean on the touched python files

Chris CoutinhoandClaude Opus 4.7 8cd3092e87 fix(storage): use NullPool for Postgres engine (cross-loop crashes under anyio TaskGroup)
The Postgres backend hit a hard crashloop in production deployments
where the MCP server runs under anyio TaskGroups with multiple
concurrent background tasks (`vector.oauth_sync.user_manager_task`,
processors, etc.) alongside the request-path code. Symptom in the
pod logs:

  RuntimeError: Task <Task pending name='nextcloud_mcp_server.vector.oauth_sync.user_manager_task'>
    got Future <Future pending cb=[BaseProtocol._on_waiter_completed()]>
    attached to a different loop

followed seconds later by

  RuntimeError: Event loop is closed

while SQLAlchemy's pool tries to clean up the failed connection.
The event loop becomes increasingly unresponsive as asyncpg
protocol Futures pile up holding references to closed loops; the
`/health/live` endpoint eventually misses its probe window and
the kubelet SIGKILLs the pod (exitCode 137), restart-looping the
backend.

Root cause: the engine was built with the default
`AsyncAdaptedQueuePool` (`pool_size=2, max_overflow=5`) and
`pool_pre_ping=True`. asyncpg connection objects are bound to the
event loop they were created on. When the process holds a
singleton engine and tasks running under different anyio
TaskGroups check out connections from that pool, the pre-ping
probe runs on a cached connection whose underlying transport
references a different loop's selector → cross-loop access →
crash.

Switch to `NullPool` — one fresh asyncpg connection per
`engine.connect()`, no caching, no cross-loop bookkeeping to get
wrong. asyncpg connection setup is ~5 ms over LAN and a single
round-trip in the local-Postgres case, so the throughput cost is
negligible for the MCP server's traffic shape (low concurrency,
bursty per-user requests). This matches what the SQLite branch
already does (see `initialize()`) and what Alembic's `env.py`
uses for migrations, so the codebase is now consistent across
all backends.

`DATABASE_POOL_SIZE` / `DATABASE_MAX_OVERFLOW` config knobs are
preserved for backward compatibility but no longer affect the
Postgres engine. The validators in `config.py` continue to
reject values < 1 / < 0, so misconfigured deploys still fail
loudly. A follow-up could mark them deprecated in
`docs/configuration.md`; out of scope here.

Discovered while smoke-testing the per-tenant Postgres flow in
Astrolabe Cloud (every-tenant pod fresh-provisions a database
via the ADR-026 backend → hits this crashloop within ~5 min of
the first MCP-routed request).

Refs:
- ADR-026 § "Concurrency model and pool sizing" (the original
  QueuePool rationale, now superseded by this finding)
- nextcloud_mcp_server/alembic/env.py (NullPool for migrations)
- SQLAlchemy docs: NullPool is the documented choice when
  connection objects don't survive across the lifecycle of the
  pool's logical "owner" (here: the event loop)

Verified:
- `uv run ruff check nextcloud_mcp_server/auth/storage.py` clean
- `uv run pytest tests/unit/test_*storage*.py` → 29 passed

Chris Coutinho 39d70cfdf5 chore: Update third_party/astrolabe 2026-05-17 10:53:55 +02:00
Chris CoutinhoandClaude Opus 4.7 d717c64750 fix(storage): address PR #798 round-4 review (NOSONAR syntax + pg_advisory_lock + engine dispose + nits)
Addresses all 8 items in the round-4 bot review plus 4 remaining
SonarQube OPEN issues that were silently broken by round 3's
malformed NOSONAR markers.

NOSONAR syntax fix (clears the remaining 4 OPEN SQ issues)
----------------------------------------------------------
Round 3 used ``# NOSONAR S<rule_key>`` form. SonarQube Python doesn't
recognize the rule-key suffix — it treats the whole thing as a
malformed suppression directive (S7632) AND lets the underlying rule
keep firing (S7503 on ``_Cursor.__aenter__/__aexit__``).

Switch every marker to bare ``# NOSONAR``, with the rationale moved
into a preceding comment block. Affected sites:
- storage.py: ``_Cursor.__aenter__``, ``_Cursor.__aexit__``
- config.py: ``get_database_ssl()`` ``return False`` + ``ssl.create_default_context()``
- test_storage_logging.py: ``SENTINEL_PASSWORD_FRAGMENT`` constant
- test_storage_postgres.py: three ``bob_pw_v1`` / ``bob_pw_v2`` / ``carol_pw`` literals

Bot 🔴#1 — defensive NOSONAR on get_database_ssl `return False`
--------------------------------------------------------------
Bot predicted S4830 fires on the operator-opt-out path. SQ output
shows it doesn't currently fire, but bare NOSONAR added defensively
with rationale comment.

Bot 🔴#2 — defensive NOSONAR on f-string SQL
--------------------------------------------
``update_oauth_session`` builds its SET clause via ``f"{', '.join(update_fields)}"``;
``get_audit_logs`` builds its WHERE clause via string concatenation.
Both are safe (the fragments only come from this function's own
branches, no user input), but the patterns trip taint analysers.
Annotated both with bare NOSONAR + safety comment explaining the
hardcoded-fragments invariant. Note: S2077 doesn't currently fire
on these; defensive.

Bot 🟡#3 — pg_advisory_lock for concurrent migrations
-----------------------------------------------------
Without coordination, two pods rolling-updating simultaneously can
both observe ``has_alembic=False`` and both try to apply migrations
from scratch — the second crashes with "relation already exists".

New ``_migration_lock()`` async context manager:
- On Postgres: ``SELECT pg_advisory_lock(:lock_id)`` on a fresh
  connection (separate from the engine pool so it survives the
  ``to_thread.run_sync`` worker), held across BOTH the schema-inspect
  AND the migration call. Without that span, two pods could each
  observe "no alembic_version" before either started migrating,
  defeating the lock.
- On SQLite: yields immediately (file-level locking serializes
  writes natively).

Lock ID derived from
``sha256(b"nextcloud-mcp-server:migrations")[:8]`` as a stable signed
int64 so we can't collide with other apps sharing the same Postgres.

Bot 🟡#4 — RefreshTokenStorage.close() + lifespan wiring
--------------------------------------------------------
New idempotent ``close()`` method calls ``await engine.dispose()``,
nulls the engine, resets ``_initialized``. Wired into both
``app_lifespan_basic`` (BasicAuth) and the OAuth lifespan teardown,
each wrapped in ``try/except Exception`` with ``logger.warning`` so a
buggy dispose can't block SIGTERM. Without this, pooled asyncpg
connections leak server-side slots until
``idle_in_transaction_session_timeout`` reaps them — with small pool
defaults and frequent k8s rolling restarts this can starve
``max_connections``.

Bot 🟢#5 — is_sqlite_url docstring on :memory:
----------------------------------------------
Updated docstring to note both file-backed and in-memory forms are
recognized; caller is responsible for ``:memory:`` magic.

Bot 🟢#6 — db_path via make_url(...).database
---------------------------------------------
Replaced ``database_url.split("///", 1)[1]`` hack with SQLAlchemy's
own URL parsing. Naturally handles in-memory (``.database is None``
→ falls back to ``""``). Same lazy-import pattern as the existing
``mask_db_password`` to avoid module-import-time cost.

Bot 🟢#7 — _to_sync_url unrecognized-driver guard
-------------------------------------------------
Pulled ``_KNOWN_ASYNC_DRIVERS = ("aiosqlite", "asyncpg")`` into a
module constant. When an unrecognized ``+<driver>`` token survives
the strip, emits ``logger.warning`` with the known-supported list.
Behavior unchanged for valid URLs.

Bot 🟢#8 — get_audit_logs SELECT * → explicit columns
-----------------------------------------------------
Replaced ``SELECT *`` with explicit column list. Future schema
additions stay out of the dict return.

New tests
---------
- ``test_close_disposes_engine``: pins the public contract — engine
  nulled, state reset, second call is a no-op.
- ``test_concurrent_initialize_serialized_by_advisory_lock``: spawns
  3 concurrent inits against a fresh schema; asserts no "relation
  already exists" and exactly one ``alembic_version`` row at the end.
  Without the lock, this reliably fails on the second concurrent
  task.

Docs
----
- ADR-026: new "Concurrent migrations across pods" subsection
  documents the advisory-lock approach + lock-ID derivation.

Verification
------------
- ``uv run pytest tests/unit/`` — 1025 passed.
- ``TEST_DATABASE_URL=… uv run pytest tests/integration/test_storage_postgres.py -m postgres`` — 9 passed (was 7).
- ``ruff check && ruff format --check && ty check`` — clean.

Expected post-push: SQ scan reports 0 OPEN issues (was 4).

Tracked on Astrolabe Cloud POC board, card #99.

Chris CoutinhoandClaude Opus 4.7 51419329b0 fix(storage): address PR #798 round-3 review (SonarQube + pool sizing + RETURNING test)
Round-3 fixes. Two threads:
- 9 OPEN SonarQube issues caused the "E Security Rating on New Code"
  gate failure. The bot's diagnosis (sa.text(text_sql) → SQL injection)
  was a wrong guess; the actual SQ rules firing were different.
- Bot's substantive concerns: pool defaults too aggressive,
  delete_browser_session RETURNING path untested on Postgres,
  schema_version legacy table created on Postgres, stale module
  docstring.
- User's underlying question on the pool: "isn't 1 connection enough?"
  Right-sized to 2+5 and documented the concurrency model in ADR-026
  so the rationale is durable.

SonarQube quality-gate fixes (clears all 9 OPEN issues)
-------------------------------------------------------
- BLOCKER S6418: rename `SECRET` constant in test_storage_logging.py
  to `SENTINEL_PASSWORD_FRAGMENT` + NOSONAR with rationale.
- CRITICAL S3776: extract `_build_postgres_engine()` from
  `initialize()` (was complexity 26 > 15); incidentally creates a
  clean unit-test seam for engine args.
- CRITICAL S4423: `ssl.create_default_context(cafile=...)` is flagged
  as "weak protocol" — Python 3.10+ already negotiates the strongest
  available protocol. Explicitly pass `purpose=ssl.Purpose.SERVER_AUTH`
  and NOSONAR with the Python-version rationale.
- MAJOR S3358: split the TLS-mode nested ternary in the engine
  factory into a `_describe_ssl_arg()` helper.
- MAJOR S2068 ×3: bind test app-password literals to local vars and
  put `# NOSONAR S2068` on the same line as the literal (anchoring
  requirement) instead of on the closing paren.
- MINOR S7503 ×2: `# NOSONAR S7503` on `_Cursor.__aenter__/__aexit__`
  — they MUST be `async` per the context-manager protocol.

Pool sizing right-sized (answers "why so many connections?")
------------------------------------------------------------
- `DATABASE_POOL_SIZE` default 10 → **2**.
- `DATABASE_MAX_OVERFLOW` default 20 → **5**.
- Per-pod max drops from 30 to 7. With 3 replicas, total = 21
  connections (was 90) — well under managed-Postgres
  `max_connections=100`.
- New INFO log at startup: `Postgres engine ready: pool_size=N
  max_overflow=M (per-pod max K connections)`. Surfaces the active
  sizing without grepping config.
- New ADR-026 § "Concurrency model and pool sizing" explains
  asyncpg's single-flight connection semantics, the MCP workload
  shape (read-mostly point lookups), why-not-1 (multi-user
  serialization), and the tune-up/tune-down recipe.
- `docs/configuration.md` table updated with new defaults +
  homelab-vs-prod tuning guidance, linking the ADR.

RETURNING path covered on Postgres
----------------------------------
- New `test_browser_session_delete_returning` exercises the
  `DELETE … RETURNING user_id` path — the only RETURNING clause in
  the storage layer and the most dialect-sensitive SQL in this PR.
  Asserts both present-row (returns True, row gone) and absent-row
  (returns False) branches.

Schema portability polish
-------------------------
- `alembic 001`: gate `schema_version` table creation on
  `op.get_bind().dialect.name == "sqlite"`. The table exists purely
  to match the fingerprint of pre-Alembic SQLite databases; fresh
  Postgres installs no longer carry the dead legacy table.

Misc polish
-----------
- Module docstring: "SQLite-based" → "SQL-backed", with a sentence
  on the DATABASE_URL opt-in and an ADR-026 link.
- Comment on `_wrap_row` noting `row._mapping` is the documented
  RowMapping accessor in SQLAlchemy 2.x despite the underscore.

Skipped (rationale in PR reply)
-------------------------------
- `_qmark_to_named` SQL-comment handling: docstring already notes
  the limitation; no `?` in storage SQL comments today.
- Module-level `anyio.Lock()`: established precedent confirmed by
  the bot itself.
- `get_audit_logs` `SELECT *`: pre-existing pattern, out of scope.

Verification
------------
- `uv run pytest tests/unit/` — 1025 passed.
- `TEST_DATABASE_URL=… uv run pytest tests/integration/test_storage_postgres.py -m postgres` — 7 passed.
- `ruff check && ruff format --check && ty check` — clean.
- Confirmed `schema_version` absent on fresh Postgres, still present
  on fresh SQLite.

Chris CoutinhoandClaude Opus 4.7 f2b7bf132f fix(storage): address PR #798 review feedback (credentials, asyncpg extra, TLS, pool)
Round-2 fixes after the bot review on PR #798 plus two user follow-ups
(self-signed Postgres support; asyncpg should be a PyPI extra). Folded
into the same PR rather than a follow-up since the work is still
unmerged.

Security
--------
- Mask database credentials in all 5 log call sites (storage.py × 4,
  migrations.py × 1) via a new `mask_db_password()` helper in config.py.
  Uses SQLAlchemy's `make_url(...).render_as_string(hide_password=True)`
  with a regex fallback so the masking path never raises.
- New `tests/unit/test_storage_logging.py` asserts a sentinel password
  never appears in `caplog` during `RefreshTokenStorage.initialize()`.

Distribution
------------
- `asyncpg` moved to `[project.optional-dependencies] postgres` so a
  vanilla `pip install nextcloud-mcp-server` no longer pulls in the
  ~5 MB C extension. The Docker image runs `uv sync --extra postgres`,
  so containerized deployments are unchanged.
- When `DATABASE_URL=postgresql+asyncpg://...` is set on a venv missing
  the extra, `RefreshTokenStorage.initialize()` raises a friendly
  RuntimeError pointing at `[postgres]` rather than the generic
  ModuleNotFoundError.

TLS for the Postgres backend
----------------------------
- New `DATABASE_VERIFY_SSL` + `DATABASE_CA_BUNDLE` env vars mirror the
  existing `NEXTCLOUD_VERIFY_SSL` / `NEXTCLOUD_CA_BUNDLE` pattern
  (validators in Settings.__post_init__, `get_database_ssl()` helper
  alongside `get_nextcloud_ssl_verify()`). `DATABASE_VERIFY_SSL=false`
  wins over `DATABASE_CA_BUNDLE` for incident-response convenience.
- Default is **None** rather than True — keeps PR #798's behavior
  intact for cluster-internal Postgres that runs without TLS. Operators
  opt into verify-full or supply a private CA. ADR-026 records the
  reasoning vs the Nextcloud HTTPS default.
- Engine factory in `storage.py` passes `ssl` via `connect_args` only
  when `get_database_ssl()` returns non-None; otherwise asyncpg's
  default (`prefer`) applies.
- Storage logs which TLS mode is active at INFO (no secret material).

Configurable connection pool
----------------------------
- `DATABASE_POOL_SIZE` (default 10) and `DATABASE_MAX_OVERFLOW`
  (default 20) replace the hardcoded engine values. With many replicas
  this can blow past managed-Postgres `max_connections=100`; tune down
  for large fleets.
- gte-1 / gte-0 validators in __post_init__ reject 0/negative pool
  sizes at startup with the offending value in the error.

Consistency polish
------------------
- Migration 006: convert raw `op.execute("ALTER TABLE ... ADD COLUMN")`
  to `op.batch_alter_table(...).add_column(sa.Column("nonce", sa.Text))`
  for stylistic consistency with the rewritten 001-005. Downgrade now
  drops the column instead of being a no-op.
- `registered_webhooks.created_at` standardized from `sa.Float` to
  `sa.BigInteger` (all other `*_at` columns); `store_webhook()` casts
  `time.time()` → `int`.
- `is_sqlite_url()` made case-insensitive.

Testing
-------
- New `tests/integration/test_storage_postgres.py::test_cleanup_expired_roundtrip`
  exercises `cleanup_expired_tokens`, `cleanup_expired_sessions`, and
  `cleanup_expired_browser_sessions` — relies on DELETE rowcount,
  historically dialect-tricky.
- `tests/unit/test_ssl_config.py` extended with `TestDatabaseSSLSettings`
  + `TestGetDatabaseSSL` classes (9 new tests) mirroring the existing
  Nextcloud SSL tests one-for-one.

Docs
----
- `docs/configuration.md` Centralized-Storage section grew the four new
  env vars + a homelab example with a private CA.
- `docs/ADR-026` grew Distribution, TLS, and `alembic/env.py` async-pattern
  subsections explaining the non-obvious design choices.

Helm chart counterpart in cbcoutinho/helm-charts PR #34 (separate
commit on `feat/nextcloud-mcp-server-database-url`).

Verification
------------
- `uv run pytest tests/unit/` — 1025 passed.
- `TEST_DATABASE_URL=... uv run pytest tests/integration/test_storage_postgres.py -m postgres` — 6 passed (including new cleanup test).
- `uv run ruff check && uv run ruff format --check && uv run ty check -- nextcloud_mcp_server` — clean.

Chris CoutinhoandClaude Opus 4.7 292cbb3292 feat(storage): pluggable database backend via DATABASE_URL (ADR-026)
Adds a `DATABASE_URL` setting that lets `RefreshTokenStorage` run against
any SQLAlchemy async backend, primarily `postgresql+asyncpg://...` for
HA k8s deployments. Default behavior is unchanged: when `DATABASE_URL` is
unset the server falls back to the existing `TOKEN_STORAGE_DB` path /
ephemeral SQLite tempfile.

Why
---
Today every MCP pod needs its own PVC to hold the SQLite file, which
pins the Deployment to one replica and blocks horizontal scaling. With
this change, operators can point all replicas at a shared Postgres
(CNPG, RDS, etc.) and the pods become stateless. Encryption stays in
Python (Fernet); the database only sees ciphertext.

What changed
------------
- `config.get_database_url()` resolves DATABASE_URL → TOKEN_STORAGE_DB →
  ephemeral tempfile in that priority order.
- `RefreshTokenStorage` builds a process-shared `AsyncEngine` in
  `initialize()`. SQLite gets NullPool; Postgres gets pool_size=10,
  max_overflow=20, pool_pre_ping=True. 30 aiosqlite call sites adapted
  via a thin `_DBConn` / `_Cursor` / `_Row` / `_ExecuteCtx` shim so
  existing method bodies need no churn beyond the connection
  context-manager swap.
- 7 `INSERT OR REPLACE` statements rewritten as portable
  `INSERT ... ON CONFLICT (...) DO UPDATE` (SQLite ≥ 3.24, Postgres ≥ 9.5).
- `sqlite_master` legacy-detection lookup replaced with SQLAlchemy
  inspector so the path works against either backend.
- File-permission hardening + parent-dir creation gated on
  `is_sqlite_url(...)` — centralized backends manage their own filesystem.
- Alembic migrations 001/002/003/005 converted from raw `op.execute(SQL)`
  to portable `op.create_table()` / `op.create_index()` with SQLAlchemy
  types. All timestamp columns are `sa.BigInteger` so Postgres allocates
  BIGINT (unix epochs don't fit in INT4). SQLite treats BIGINT as
  INTEGER, so existing deployments at revision 006 see no schema drift.
- `migrations.py` + CLI take URLs; `db {upgrade,downgrade,current,history}`
  gain `--database-url / -u` alongside the legacy `--database-path / -d`.
  `get_current_revision()` uses SQLAlchemy inspector instead of raw
  sqlite3, so the CLI works against Postgres too.
- `docker-compose.yml` adds a `postgres-test` service under the
  `postgres` profile (pinned `postgres:16-alpine` digest) for
  integration testing.
- Unit storage tests parametrized over backends via shared
  `tests/fixtures/storage_backend.py` — every test in
  `test_app_password_storage.py` and `test_webhook_storage.py` runs
  once per backend that is available. Postgres is opted in by
  `TEST_DATABASE_URL`.
- New `tests/integration/test_storage_postgres.py` (5 tests, marked
  `postgres` + `integration`) covers refresh-token, app-password,
  OAuth-session, webhook, and audit-log paths end-to-end on Postgres.
- New `docs/ADR-026-pluggable-database-backend.md` records the decision;
  `docs/configuration.md` documents `DATABASE_URL` with examples.

Out of scope
------------
- No SQLite → Postgres data migration tool (clean cutover; tokens reissue
  on next login, webhooks re-register on next sync tick).
- This repo does not provision Postgres. The matching helm chart change
  lives in cbcoutinho/helm-charts (database.url / existingSecret values).

Verification
------------
- `uv run pytest tests/unit/` — 1012 passed, SQLite path unchanged.
- `docker compose --profile postgres up -d postgres-test`
- `TEST_DATABASE_URL=... uv run pytest tests/integration/test_storage_postgres.py -m postgres -v`
  — 5 passed.
- `TEST_DATABASE_URL=... uv run pytest tests/unit/test_app_password_storage.py
  tests/unit/test_webhook_storage.py` — 50 passed (25 per backend).
- `uv run ruff check && uv run ruff format --check && uv run ty check -- nextcloud_mcp_server` — clean.

Chris CoutinhoandClaude Opus 4.7 79ea4e9e21 fix(config): emit background-ops advisory logs once per process
`_get_background_operations_enabled()` was emitting three advisory log
lines (1 INFO + 2 deprecation WARNINGs) on every call. Because
`get_settings()` is intentionally non-cached and runs on every MCP tool
invocation via `get_client()`, the "Automatically enabled background
operations for semantic search in multi-user mode" INFO line was
firing per-request — 569 entries/hour in one production tenant.

Gate the three log emissions behind a module-level
`_bg_ops_advisories_logged` flag, mirroring the existing
`_warn_missing_secret_once` precedent in
`vector/webhook_receiver.py`. The boolean-derivation path stays
unchanged, so the `Settings` value remains fresh per call.

Extends the autouse `_reload_dynaconf_after_test` fixture to reset the
new flag between tests, and adds two regression tests that call
`get_settings()` five times and assert each advisory fires exactly once.

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 18db9d6cb3 refactor: prune dead pre-LOGIN_FLOW config/runtime branches
Two small post-merge cleanups deferred from PR #787 (ADR-022 follow-up).
Both were explicitly noted in the reviewer's "acknowledged deferred items"
list.

1. config.py: drop `enable_multi_user_basic_auth` and `enable_login_flow`
   from the dynaconf `_DEFAULTS` dict. They were removed from `_field_map`
   in PR #787, so `get_settings()` never read them anyway, but their
   presence in `_DEFAULTS` was visually misleading — readers might think
   they could be set via TOML when in fact `Settings.__post_init__`
   derives them from `MCP_DEPLOYMENT_MODE`. Replaced with a NOTE comment
   pointing at the canonical derivation site.

2. app.py: the lifespan code had
   `use_basic_auth = not oauth_enabled or settings.enable_login_flow`,
   which became always-True once PR #787 enforced
   `oauth_enabled ↔ enable_login_flow` via __post_init__. Hard-coded to
   `True` with a comment explaining the invariant and pointing at the
   separate follow-up that will prune the now-unreachable
   `use_basic_auth=False` code paths in `vector/oauth_sync.py` (which
   includes deleting the `use_basic_auth` parameter from
   `user_manager_task` / `oauth_processor_task` and the OAuth-token-refresh
   branch in `get_user_client`). Kept the variable name and the call-site
   conditionals as-is for now so that follow-up is a clean mechanical
   diff.

No runtime behaviour change: `use_basic_auth` already evaluated to True
in every supported mode after PR #787, and the `_DEFAULTS` entries were
already shadowed by `__post_init__`.

Chris CoutinhoandClaude Opus 4.7 bf424135a5 docs(adr-025): remove duplicate [login_flow] section in TOML example
Commit 4 renamed `[oauth_single_audience]` → `[login_flow]` via a global
sed pass, but ADR-025's example settings.toml already had a `[login_flow]`
section just above the `[keycloak]` block. The rename produced two
back-to-back `[login_flow]` headers with identical contents — TOML parsers
either reject the file or silently override, and a reader copying the
example would land on either outcome.

Dropped the now-duplicate second `[login_flow]` section (the renamed one).
The earlier `[login_flow]` section retains the same content + a comment
explaining the ADR-022 derivation, so no information is lost.

Chris CoutinhoandClaude Opus 4.7 0fb21b5c6d chore: address review-round-5 — stale _sync_derived_flags reference + missing migration-hint test
Two findings from the reviewer's latest pass:

- config_validators.py:329: comment in the LOGIN_FLOW validation block
  still referenced `_sync_derived_flags` (removed in commit 5; derivation
  now lives in `Settings.__post_init__`). Updated the comment to point at
  the correct location so a future reader grepping for the function name
  doesn't come up empty.
- tests/unit/test_config_validators.py: added
  `test_oauth_single_audience_migration_hint` next to the existing
  `test_invalid_deployment_mode_raises_error`. The new test pins the
  ADR-022 rename-hint branch in `detect_auth_mode` by setting
  `MCP_DEPLOYMENT_MODE=oauth_single_audience` and asserting the
  ValueError mentions both the old and new mode names plus "ADR-022".
  Without this, a future refactor could drop the hint without any test
  catching it (the prior `invalid_mode` test only asserts the generic
  "Valid values:" prefix).

No functional changes; 1010 unit tests now pass (+1 from the new hint
test).

Chris CoutinhoandClaude Opus 4.7 1fa4c82fd2 chore: address review-round-4 nits — stale delenv, upgrade hint, in-sync notes
Four small follow-ups from the reviewer's latest pass:

- tests/unit/test_stdio.py:18: the single_user_env fixture used
  monkeypatch.delenv("ENABLE_MULTI_USER_BASIC_AUTH", ...). That env var
  is no longer read after the ADR-022 follow-up; switched to delenv of
  MCP_DEPLOYMENT_MODE which is the canonical mode-selection input today.
  Comment updated to match.
- config_validators.py: when detect_auth_mode rejects an invalid
  MCP_DEPLOYMENT_MODE, surface a one-line ADR-022 migration hint if the
  rejected value is exactly "oauth_single_audience" (the most common
  upgrade pain — users carrying that value over from ADR-021 .env files).
  Other invalid values get the regular "Valid values: …" message
  unchanged.
- config.py + config_validators.py: added cross-reference comments on
  both mode-resolution sites (Settings.__post_init__ and
  detect_auth_mode) noting that they each compute the canonical mode
  independently and must be kept in sync when a new mode is added.
  Surfaces the parallel-duplication intentionally so the next maintainer
  doesn't have to discover it.
- docs/ADR-021-configuration-consolidation.md:92: appended a trailing
  comment to the historical "valid values" example, marking
  oauth_single_audience and oauth_token_exchange as removed in ADR-022.
  ADR-021 stays as the historical record; the trailer points future
  readers at the current state.

No functional changes; 1009 unit tests still pass.

Chris CoutinhoandClaude Opus 4.7 ade42b55dc docs: clear review-round-3 nits — stale login_flow_v2, duplicates, field comments
Five small findings from the reviewer's third round, plus a SonarCloud
quality-gate failure on a test fixture.

- docs/troubleshooting.md, docs/configuration.md: six pre-PR references
  to a non-existent `login_flow_v2` mode value (the actual enum value is
  `login_flow`). They predated this PR but became actively misleading
  once `detect_auth_mode` started raising ValueError for anything not in
  the mode_map. Replaced with `login_flow` via sed.
- docs/configuration-migration-v2.md: removed a duplicate
  `MCP_DEPLOYMENT_MODE=multi_user_basic` line in the troubleshooting
  section (around line 447) — same shape as the round-2 duplicate
  caught earlier in the migration-steps section. Also dropped the
  `oauth_token_exchange` row from the mode-value table around line 364
  (that enum value was removed in 57303135 and would now raise
  ValueError from detect_auth_mode).
- nextcloud_mcp_server/config.py: field comments for
  `enable_multi_user_basic_auth` and `enable_login_flow` said
  "Auto-set by detect_auth_mode()" but the derivation moved into
  `Settings.__post_init__` in the previous commit. Updated both.
- tests/unit/test_config_validators.py: SonarCloud's python:S2068
  flagged `nextcloud_password="hunter2"` in the
  `test_login_flow_mode_auto_derives_enable_login_flow_flag` fixture I
  added in commit 5 as a potentially hard-coded credential. Other
  fixtures in the same file use the literal `"password"` and aren't
  flagged (they predate the PR and SonarCloud only checks new-code).
  Switched to `"password"` to match the existing convention.

No functional changes; all 1009 unit tests still pass.

Chris CoutinhoandClaude Opus 4.7 6e7c821761 fix(config): derive mode flags in Settings.__post_init__; address review round 2
The integration jobs for `mcp-multi-user-basic` and `mcp-login-flow`
were failing with HTTP 500s. Root cause: `get_settings()` builds a
fresh Settings on every call (not cached). Commits 3 and 4 set the
derived `enable_login_flow` / `enable_multi_user_basic_auth` flags as
a side effect of `detect_auth_mode`. detect_auth_mode runs once at
startup, against the Settings instance owned by `validate_configuration`.
Every per-request call site that does `settings = get_settings()` got
a fresh Settings with both flags at their default `False` (since the
env-var aliases were dropped), causing the multi-user dispatcher in
`context.py` to take the wrong branch and crash.

Fix: move the derivation into `Settings.__post_init__`. Every Settings
instance now carries correct flags from the moment it's constructed —
no caching needed, no mutation-after-construction race. detect_auth_mode
becomes a pure reader of the already-derived state.

The legacy env-var deprecation check moves with it. It also picks up
the reviewer's truthy-string fix: previously `os.getenv(legacy)` fired
for the literal string "false" (a non-empty Python string is truthy),
which would have errored on any user with a leftover
`ENABLE_LOGIN_FLOW=false` in their `.env`. The check now only fires
when the value lowercases to one of {"1", "true", "yes", "on"}.

- nextcloud_mcp_server/config.py: extend Settings.__post_init__ with
  the legacy-deprecation block and the derived-flag derivation
  (resolve mode from deployment_mode + username/password, set flags).
- nextcloud_mcp_server/config_validators.py: drop the
  `_sync_derived_flags` helper (superseded by __post_init__). Drop the
  legacy-env-var deprecation block (moved). `detect_auth_mode` is now
  pure — no mutation. Drop the now-unused `import os`.
- tests/unit/test_config_validators.py: legacy-env-var tests now
  expect `ValueError` at `Settings(...)` construction (via `get_settings()`),
  not at `detect_auth_mode` call. Added two new tests:
    * `test_legacy_env_var_check_ignores_falsy_strings` — pins the
      truthy-string fix (reviewer round 2 finding).
    * `test_derived_flags_stable_across_get_settings_calls` — regression
      test pinning the integration-test fix (two consecutive
      `get_settings()` calls return Settings instances with the same
      derived flags).
  Also reworked `test_login_flow_mode_auto_derives_enable_login_flow_flag`
  to assert at-construction derivation (not the old mutation pattern).
- docs/configuration-migration-v2.md: dropped the duplicate
  `MCP_DEPLOYMENT_MODE=multi_user_basic` line (review round 2 nit — a
  sed artifact from commit 4).
- docs/ADR-021-configuration-consolidation.md: sed-replaced the in-body
  `MCP_DEPLOYMENT_MODE=oauth_single_audience` examples with `login_flow`
  (review round 2 nit — only the status header was updated in commit 4).
- tests/conftest.py: docstring comment for the multi-user-basic fixture
  switched from `ENABLE_MULTI_USER_BASIC_AUTH=true` to
  `MCP_DEPLOYMENT_MODE=multi_user_basic` (review round 2 nit).

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 df4994e860 refactor(config)!: derive enable_login_flow from mode, remove ENABLE_LOGIN_FLOW env var
Once OAUTH_SINGLE_AUDIENCE was renamed to LOGIN_FLOW and the validation
gate ensured the only meaningful configuration was
`MCP_DEPLOYMENT_MODE=login_flow + ENABLE_LOGIN_FLOW=true`, the two
controls became redundant. Setting the mode is sufficient; the
ENABLE_LOGIN_FLOW env var doesn't add information.

This commit makes the deployment mode the single source of truth for
the Login Flow v2 toggle:

- `nextcloud_mcp_server/config.py`: drop the `ENABLE_LOGIN_FLOW`
  dynaconf env-var alias. The `enable_login_flow` field stays as an
  internal attribute so the 6 runtime call sites (app.py x4,
  context.py, auth/scope_authorization.py) keep working unchanged.
  Updated field docstring to flag it as derived.
- `nextcloud_mcp_server/config_validators.py`:
  - Drop `enable_login_flow` from `MODE_REQUIREMENTS[LOGIN_FLOW].required`.
  - Drop the validation gate that required ENABLE_LOGIN_FLOW=true for
    LOGIN_FLOW mode (no longer possible to misconfigure — the flag is
    derived, not user input).
  - Add `_sync_derived_flags()` helper called at every return path of
    `detect_auth_mode` to set `settings.enable_login_flow` from the
    resolved mode.
- `tests/unit/test_config_validators.py`: drop `enable_login_flow=True`
  from happy-path fixtures (no longer needed — detection sets it).
  Repurpose `test_login_flow_requires_enable_login_flow_flag` into
  `test_login_flow_mode_auto_derives_enable_login_flow_flag` which
  asserts the new auto-derivation behaviour for both LOGIN_FLOW and a
  non-LOGIN_FLOW mode.
- `docker-compose.yml`: remove `ENABLE_LOGIN_FLOW=true` from the
  `mcp-login-flow` and `mcp-keycloak` profiles.
- `env.sample`: remove the ENABLE_LOGIN_FLOW reference; the comment
  on `MCP_DEPLOYMENT_MODE` now notes the derived flag.
- `docs/configuration.md`, `docs/authentication.md`,
  `docs/login-flow-v2.md`, `docs/auth-flows.md`,
  `docs/troubleshooting.md`, `docs/ADR-025-*.md`: replace
  ENABLE_LOGIN_FLOW=true examples and references with
  MCP_DEPLOYMENT_MODE=login_flow.

BREAKING CHANGE: `ENABLE_LOGIN_FLOW` is no longer read from the
environment. Anyone who relied on `ENABLE_LOGIN_FLOW=true` to activate
Login Flow v2 should set `MCP_DEPLOYMENT_MODE=login_flow` instead (or
rely on it being the default when no other auth env vars are set).

Chris CoutinhoandClaude Opus 4.7 c74ef014ee docs(adr-022): mark Accepted, update env/compose/migration docs for LOGIN_FLOW rename
Follow-up to the LOGIN_FLOW rename. The user-facing surface area —
env.sample, docker-compose.yml mcp-login-flow profile, migration
guide, ADR statuses, and the running.md boot-log examples — all need
to refer to `login_flow` rather than the deprecated
`oauth_single_audience` string.

- docker-compose.yml: add explicit MCP_DEPLOYMENT_MODE=login_flow to
  the mcp-login-flow profile (no longer relying on auto-detection).
- env.sample: update the deployment-mode list and example, dropping
  the removed `oauth_token_exchange` and pointing at ADR-022 for the
  rename rationale.
- docs/ADR-022: flip Status to Accepted with a note that this PR
  implements step 1 (rename + validation gate).
- docs/ADR-021: note that it has been partly superseded by ADR-022
  (the oauth_single_audience naming is no longer accurate); cross-link.
- docs/ADR-025: drop oauth_single_audience/keycloak from the dynaconf
  validator example and the [oauth_single_audience] TOML section.
- docs/configuration-migration-v2.md: bulk-replace oauth_single_audience
  → login_flow throughout (sed -i).
- docs/running.md: re-collapse the per-mode boot-log subsections (added
  during the closed PR #786 workaround) back into a uniform
  "<mode>"-substitution block — now correct after this PR's logging
  cleanup at app.py:1172.

Chris CoutinhoandClaude Opus 4.7 cafd318f36 refactor(config)!: rename OAUTH_SINGLE_AUDIENCE to LOGIN_FLOW, gate on ENABLE_LOGIN_FLOW
The AuthMode.OAUTH_SINGLE_AUDIENCE enum was a vestige of ADR-021's
original design where it co-existed with OAUTH_TOKEN_EXCHANGE. The
un-augmented OAuth bearer pass-through it represented relied on
Nextcloud-side patches to user_oidc (Bearer token validation on
non-OCS endpoints) that were never merged upstream (see
docs/authentication.md, docs/login-flow-v2.md). The working path —
mcp-login-flow profile — sets ENABLE_LOGIN_FLOW=true on top of this
mode so Login Flow v2 acquires per-user Nextcloud app passwords via
a browser flow. With OAUTH_TOKEN_EXCHANGE removed in 57303135, the
_AUDIENCE suffix in the Python name no longer disambiguates anything,
and the enum value diverged from the env-var spelling. ADR-022 (now
accepted) called for this rename as step 1 of consolidation.

- nextcloud_mcp_server/config_validators.py: rename enum to LOGIN_FLOW
  with value "login_flow". The mode_map key is now "login_flow"; the
  MODE_REQUIREMENTS entry requires `enable_login_flow=True`. Added a
  validation gate so MCP_DEPLOYMENT_MODE=login_flow without
  ENABLE_LOGIN_FLOW=true errors with a clear message pointing at
  ADR-022. Default auto-detection fallback returns LOGIN_FLOW.
- nextcloud_mcp_server/app.py: renamed three identifier references and
  switched the "Configuring MCP server for OAuth mode" log line to
  the uniform `mode.value` shape used by the other modes.
- nextcloud_mcp_server/api/management.py: renamed identifier in the
  /api/v1/status mapping. The user-visible "auth_mode": "oauth" string
  is preserved — that's a stable Astrolabe contract.
- nextcloud_mcp_server/config.py: updated Settings docstring.
- tests/unit/test_config_validators.py: renamed class
  TestOAuthSingleAudienceValidation → TestLoginFlowValidation,
  individual test methods, env-var strings; added enable_login_flow=True
  to fixtures expecting success; added a new test
  (test_login_flow_requires_enable_login_flow_flag) that exercises the
  validation gate.
- tests/unit/test_management_status_endpoint.py: renamed identifier.

BREAKING CHANGE: MCP_DEPLOYMENT_MODE=oauth_single_audience is no longer
accepted. Set MCP_DEPLOYMENT_MODE=login_flow (and keep
ENABLE_LOGIN_FLOW=true) for the same deployment. The un-augmented
OAuth path is no longer supported; if you previously ran the broken
path, you can either configure Login Flow v2 (recommended) or switch
to multi_user_basic / single_user_basic.

Dead-code pruning of `oauth_enabled and not enable_login_flow`
branches in app.py (lifespan, background sync) is deferred to a
separate follow-up PR per the consolidation plan in ADR-022.

Chris CoutinhoandClaude Opus 4.7 5f01312cc4 docs: correct OAuth enum value and split boot-log block by mode
Reviewer found two accuracy issues in the rewritten "Check Deployment
Mode" section:

- The AuthMode.OAUTH_SINGLE_AUDIENCE enum value is `oauth_single`, not
  `oauth_single_audience` (config_validators.py:28). A user grepping
  their container logs would have found nothing.
- The "Configuring MCP server for <mode> mode" line was presented as a
  uniform <mode> substitution, but app.py:1170 hardcodes the literal
  string `OAuth mode` for OAuth, while app.py:1239 uses the enum value
  for the two BasicAuth modes.

Split the boot-time block into per-mode subsections so each one shows
the actual literal text users will see, and add a one-line note
calling out the OAuth string difference.

Chris CoutinhoandClaude Opus 4.7 e78e191818 docs: fix /health → /health/live, refresh stale mode-detection log examples (#766)
Issue #766 reported that the running.md quick-start tells users to
`curl http://localhost:8000/health`, which returns 404 — the server
only registers `/health/live` and `/health/ready` (K8s-style probes).
The same section also listed BasicAuth and OAuth startup log lines
(`BasicAuth mode detected …`, `OAuth mode detected …`) that no longer
exist anywhere in the codebase.

Update running.md and troubleshooting.md to point at the real
endpoints, explain liveness vs readiness, and replace the fictional
log examples with messages the server actually emits today. Also
clarify that the per-session BasicAuth messages only appear after the
first MCP client connects, which is the second symptom the reporter
hit.

Docs-only change; code paths and endpoint surface unchanged.

Chris CoutinhoandClaude Opus 4.7 9d5ac01f24 fix(calendar): preserve floating/TZID semantics across CalDAV roundtrip (#782)
The CalDAV REPORT in `_search_events_by_date` unconditionally requested
server-side `<C:expand>`. Per RFC 4791 §9.6.5 the server then normalizes
every expanded DTSTART/DTEND to UTC `Z`, which destroyed two pieces of
information on the read path:

- RFC 5545 floating local times came back as fake-UTC (a `+00:00` suffix
  that did not match the stored value), so a 2:30 PM floating event was
  indistinguishable from a 14:30 UTC event in the MCP response.
- TZID-bound events lost their IANA TZID context — a "10am America/New_York"
  event came back as `14:00:00+00:00`, making it impossible for callers to
  reconstruct DST-aware recurrence semantics.

Replace `<C:expand>` with client-side recurrence expansion via the
`recurring-ical-events` library (promoted from transitive to direct dep),
so the wire response retains its original DTSTART format. Surface the
TZID parameter as new `start_tz`/`end_tz` fields on `CalendarEventSummary`.

Add an optional `timezone` (IANA name) parameter to `nc_calendar_create_event`
and `nc_calendar_update_event` so callers can pin a TZID for naive input;
the helper attaches `ZoneInfo(...)` and emits a paired `VTIMEZONE`
component. Naive input without `timezone` continues to store as RFC 5545
floating local time (with a warning logged). Offset-aware input continues
to store as UTC `Z`.

Drive-by: switch the update path's DTSTART/DTEND assignment from raw
`datetime` to `vDDDTypes(dt)` wrappers — the previous code produced invalid
iCal like `DTSTART:2026-05-14 10:00:00+00:00` for any TZ-aware update.

Chris CoutinhoandClaude Opus 4.7 271904c227 fix(deck): address review — notesPath key, scopes, modernize types
PR #781 review round 1:

- 🔴 Fix notesPath key: the Notes API returns the folder under camelCase
  ``notesPath`` (see models/notes.py:43), but `deck_attach_note` was
  looking up snake_case ``notes_path`` and silently falling back to
  ``"Notes"``. Users with a non-default notes folder would have produced
  shares pointing at non-existent files (404 on click in Deck UI).

- 🔴 Add wire-through unit test that would have caught the above:
  extract `_resolve_note_attach_path(client, note_id)` as a testable
  helper that encapsulates the camelCase-key lookup. Three new tests:
  custom notesPath honored, missing key falls back to default, null
  category handled.

- 🟡 Modernize new fields on `DeckAttachmentExtendedData` to PEP 604
  (`X | None`) per CLAUDE.md.

- 🟡 Drop unnecessary string forward reference on
  `ListAttachmentsResponse.results` — DeckAttachment is defined earlier
  in the same module.

- 🟢 Move `pytestmark = pytest.mark.unit` to module level in
  test_sharing_client.py to match the convention in test_deck_server.py.

Per user request: `deck_attach_file` is now scoped `deck.write` +
``files.read`` (was just `deck.write`) so the generic file-share
permission story is consistent — only `deck_attach_note` keeps
`notes.read` since it specifically reads from the Notes app. Docstring
updated to emphasise the tool is generic over the user's Files
(PDFs/images/etc., not just markdown).

Chris CoutinhoandClaude Opus 4.7 c0a974c498 feat(deck): add file/note attachment MCP tools
Adds four tools that expose Deck card attachments via the MCP surface:
deck_attach_file, deck_attach_note, deck_list_attachments, and
deck_delete_attachment. The attach* variants share an existing Files
entry (or Notes-app note) with the card via OCS shareType=12 — same
mechanism the Deck UI's "Share from Files" picker uses, no file copy.

This replaces the prior workaround of appending bulky activity content
as Deck card comments: per-PR/per-event narrative now lives in NC Notes
and surfaces on the tracking card as a clickable attachment that opens
the original note in place.

Implementation reuses existing client methods (SharingClient.create_share,
DeckClient.get/delete_attachment, NotesClient.get_settings/get_note);
no new client code. _SHARE_TYPE_DECK is centralised with a CI-guard test
to prevent silent drift, and SharingClient.create_share's wire format is
pinned to what the Deck Vue source sends.

Chris CoutinhoandClaude Opus 4.7 9cb0b33ec1 fix(health): forward api-key to Qdrant /readyz so Cloud probes work
The readiness handler called the configured `qdrant_url/readyz` with a
bare httpx.AsyncClient — no headers. That works against a self-hosted
Qdrant (where /readyz is anonymous), but Qdrant Cloud's auth gateway
returns 403 for any unauthenticated request, including /readyz, /livez
and /healthz. Result: every probe against a Cloud cluster fell into
the "status 403" branch, the handler returned 503, and the Pod never
went Ready — even when the configured `AsyncQdrantClient` itself was
authenticating fine for actual collection traffic.

Forward `settings.qdrant_api_key` as the `api-key` header (mirroring
what `vector/qdrant_client.py:540` already does for the real client).
When the key is unset (self-hosted, anonymous case) we send no header,
so existing self-hosted deployments are unchanged.

Verified end-to-end against Qdrant Cloud:
- Without header: GET /readyz -> 403 {"error":"forbidden"}
- With api-key:  same request shape returns 200 (matches what
  AsyncQdrantClient.wait() relies on internally).

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.

Chris CoutinhoandClaude Opus 4.7 c5020d9629 fix(vector): address PR review round 14 — accurate offset-skip comment + news_item doc_id guard
Round-14 review surfaced one blocking and one important issue.

context.py: the comment justifying `skip_offset_lookup` claimed
chunk_start/end_offset weren't in _PAYLOAD_INDEX_FIELDS — round 13
indexed both as INTEGER, so the comment now actively misleads. Replace
with the real reason: an indexed chunk_index miss is canonical (both
paths hit the same Qdrant collection), and skipping the offset filter
avoids a redundant round-trip.

verification.py: hoist an is_valid_nextcloud_doc_id guard before the
`int(d)` cast in _verify_news_items, mirroring the boundary-validation
pattern already in _fetch_document_text. Coerce via `str(d)` because
SearchResult.id is `int | str` (D1 forward-compat widening). Malformed
ids now surface as a logger.warning rather than a generic debug line;
fail-open semantics are preserved.

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 d60348e77b fix(api): validate doc_id at chunk-context handler boundary
Add an .isdigit() guard at the top of both chunk-context handlers so a
non-numeric doc_id fails fast with a clear 400 ("doc_id must be numeric,
got 'abc'") rather than silently bottoming out as a 404 from deep inside
get_chunk_with_context. The earlier int(doc_id) coercion was removed when
doc_id became a pure pass-through to Qdrant's keyword payload index, which
also dropped this boundary validation.

Also align test_backfill_emits_progress_log_every_20_batches' scroll stub
with real Qdrant: next_offset is now "next-1" (str) instead of 1 (int),
matching the sibling test_backfill_rewrites_int_doc_ids_to_str. Pure
stub-fidelity fix; production code already treats next_offset as opaque.

Addresses both 🟡 Important items from PR #773 review round 10.

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
- ty check -- nextcloud_mcp_server: clean
- uv run pytest tests/unit/: 969 passed

Chris CoutinhoandClaude Opus 4.7 0c14501a2b test: align CI assertions with documented contracts
Two unrelated CI failures on this branch, one fix each:

- tests/integration/test_deck_vector_search.py: pass str(card.id) to
  get_chunk_with_context. The function's contract is doc_id: str
  (keyword-indexed in Qdrant), and real callers (viz_routes.py URL
  path, server/semantic.py via str(result.id)) all stringify. The
  test was the only int caller, hitting the .isdigit() guard added
  earlier on this branch.

- tests/server/login_flow/test_login_flow_integration.py:
  test_check_status_provisioned now accepts scopes=None as valid.
  Per ProvisionStatusResponse in models/auth.py, None is the
  documented sentinel for "all scopes granted" — and the web
  provisioning path (provision_routes.py, used by Astrolabe's
  "Enable Semantic Search" flow exercised by the new regression test
  added on this branch) stores exactly that. The previous
  is-not-None assertion hid behind test order until that flow ran.

- Replace anyio.sleep(0) with anyio.lowlevel.checkpoint()
