Add a modified_after/modified_before date-range filter to semantic search,
honoured on both the MCP tool path (BM25HybridSearchAlgorithm) and the
dense-only visualization/API path (SemanticSearchAlgorithm) through one shared
contract.
- Promote modified_after/modified_before to explicit keyword params on the
SearchAlgorithm ABC and both concrete algorithms; factor the shared
placeholder+ownership+doc_type+date filter into
access_filter.build_base_filter_conditions so new filters land in one place.
- nc_semantic_search: accept RFC 3339 / ISO 8601 (or Unix seconds) bounds via
utils.validation.parse_modified_timestamp; Annotated/Field constraints on the
numeric args; explicit McpError guard for after > before. Thread the parsed
bounds through the cross-app and per-doc_type dispatch.
- /api/v1 search endpoints + viz route parse the same formats and 400 on bad or
inverted ranges.
- Add a modified_at INTEGER payload index to _PAYLOAD_INDEX_FIELDS; the
idempotent _ensure_payload_indexes() startup path migrates existing
collections with no content re-index.
- Update ADR-027 to resolve the review feedback (validation placement, shared
algorithm contract, deferral of nc_semantic_search_answer, payload index,
RFC-3339-at-the-boundary rationale). Add unit tests.
Refs ADR-027. Deck #177.

- 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.

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.

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.

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
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.

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.
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.

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).

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.

- payload_backfill: drop parsed_at from the backfilled-keys docstring (it is
per-document state, not a deployment scalar); add a clean 404 precondition
for BasicAuth deployments without an OAuth token verifier.
- status.py: task_status typed TaskStatus | None (drop type: ignore).
- nats.py: TODO to thread etags for file/deck/news; note etag default → None.
- factory: warn on unknown INGEST_BUS_URL scheme; raise ValueError instead of

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.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- get_indexed_doc_types: add optional accessible_owners param and reuse
build_ownership_filter so cross-user doc-type discovery matches the real
search scope (was self-only / ACL-blind); docstring documents the self-only
default. Covered by test_get_indexed_doc_types_is_acl_aware.
- access_filter: build_ownership_filter now omits the owner_id branch entirely
for an empty owner set instead of relying on undocumented MatchAny(any=[])
semantics; updated the empty-list unit test accordingly.
- access_filter: make the uid_owner/owner share-owner extraction explicit
("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
targeted multi-user test (owner + recipient True, non-recipient False).
- viz_routes: comment that verify-on-read eviction runs inline by design (no
lifespan task group available on the Starlette route).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- 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.

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).

- S6418 "hard-coded token": NOSONAR on the Login Flow v2 poll-token test fixture.

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
minted JWT with no provisioning (replaces the obsolete login_flow_provisioning
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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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`).

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`

`_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.

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.

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).

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.

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.
