Chris CoutinhoandClaude Opus 4.8 e4d81d47d9 feat: harmonize MCP tool + userinfo page to documents/chunks model
Extend the documents-vs-chunks split to the remaining status surfaces so all
three report consistently (Deck #195):

- nc_get_vector_sync_status MCP tool + VectorSyncStatusResponse: add
  indexed_documents (distinct) and indexed_chunks; keep indexed_count as a
  deprecated alias of indexed_chunks. Reuses count_indexed.
- userinfo HTML page (/app/vector-sync/status): show Indexed Documents AND
  Indexed Chunks rows; switch its count to count_indexed (which also excludes
  placeholder points — the old raw count included them).
- /api/v1/vector-sync/status: restore indexed_count as a deprecated alias of
  indexed_chunks so existing consumers (integration tests, pre-#115 UI) keep
  working; the change is now purely additive for indexed_count.

Tests: VectorSyncStatusResponse documents/chunks/alias + zeroed defaults.

Chris CoutinhoandClaude Opus 4.8 fbe70ecd9c feat: backend-agnostic vector-sync gauges (pending/documents/chunks)
The only queue metric, mcp_vector_sync_queue_size, was updated inline by the
single-user consumer (processor_task) but never by the multi-user consumer
(oauth_processor_task). On multi-user tenants (e.g. blackbox-demo, 5 users) the
gauge read 0 for 24h while the live anyio buffer held ~2214 pending documents
(shown by /api/v1/vector-sync/status). The "indexed" figure was also a chunk
count (16039 points ≈ 480 docs) mislabelled as documents.

Publish a consumer-independent snapshot from a periodic task
(vector/metrics_publisher.vector_sync_metrics_task), spawned in BOTH lifespan
task groups (single-user and multi-user) and every queue backend:
- mcp_vector_sync_pending_documents — outstanding work via
  ingest_status.get_ingest_pending() (anyio buffer depth or procrastinate
  todo+doing); also keeps the legacy queue_size gauge meaningful on all paths.
- mcp_vector_sync_indexed_documents — distinct documents, counted exactly and
  cheaply via the one chunk_index=0 point per document (no facet).
- mcp_vector_sync_indexed_chunks — total non-placeholder points.

The /api/v1/vector-sync/status endpoint now returns indexed_documents (distinct
docs) AND indexed_chunks separately, so documents and chunks are no longer
conflated. The publisher uses approximate Qdrant counts (every-N-seconds gauge);
the on-demand endpoint counts exactly. New knob:
VECTOR_SYNC_METRICS_REFRESH_INTERVAL (default 20s). Fail-safe: a metrics refresh
never disturbs ingest.

BREAKING CHANGE: /api/v1/vector-sync/status field `indexed_documents` now holds
the distinct-document count (was the chunk count); the chunk count moved to the
new `indexed_chunks` field. The Astrolabe UI + the nc_get_vector_sync_status MCP
tool / userinfo page are harmonized in a follow-up (Deck #195).

Chris CoutinhoandClaude Opus 4.8 21b7922bac feat: replace NATS ingest with procrastinate Postgres queue (#183)
Re-architect document ingest from the shared NATS-glued document-processor to a
per-tenant, in-process model owned by nextcloud-mcp-server (Deck #183). The MCP
server now owns both sides of ingest:

- Producer (api role): the scanner defers one job per changed document into the
  app's Postgres via procrastinate (queueing_lock dedup; no execution lock, so a
  crashed worker can't deadlock a doc — Qdrant upserts are idempotent).
- Consumer (worker role): `nextcloud-mcp-server worker` drains the queue and runs
  the existing process_document pipeline; a periodic task reclaims jobs orphaned
  in `doing` by a crash.

INGEST_QUEUE selects the transport (auto: postgres when DATABASE_URL is Postgres,
else the in-process anyio queue for SQLite/dev). procrastinate manages its own
tables (applied on a fresh DB at startup and by `db upgrade`). The vector-sync
status surface reads job counts from Postgres in postgres mode. procrastinate +
psycopg3 ship in the [postgres] extra; the app's own engine still uses asyncpg
(driver unification is a follow-up handled in the rendered Helm chart).

NATS JetStream, the Postgres-queue stub, the bus status subscriber, and nats-py
are removed.

BREAKING CHANGE: the external-NATS-ingest env vars are removed
(INGEST_MODE, STATUS_BACKEND, INGEST_BUS_URL, INGEST_BUS_NUM_REPLICAS,
FACT_EVENT_EMITTER). Use INGEST_QUEUE (memory|postgres) and the `worker`
command instead. TENANT_ID is retained (no longer NATS-subject-charset-validated).

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

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

Chris CoutinhoandClaude Opus 4.7 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 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 4.5 d5544a7731 refactor(astrolabe): replace client-side PDF.js with server-side PyMuPDF rendering
Replace the client-side PDF.js viewer with server-side rendering using PyMuPDF.
This avoids CSP worker restrictions and ES private field access issues that
affected Chromium browsers.

Changes:
- Add /api/v1/pdf-preview endpoint to MCP server (management.py)
- Add pdf-preview route and controller action in Astrolabe PHP backend
- Refactor PDFViewer.vue to display server-rendered PNG images
- Remove pdfjs-dist dependency and client-side PDF loading code
- Use @nextcloud/axios for CSRF token handling in PDFViewer

The server downloads the PDF via WebDAV, renders the requested page with
PyMuPDF at the specified scale, and returns a base64-encoded PNG image.

Chris CoutinhoandClaude Opus 4.5 e486e92f91 fix(auth): Store app passwords locally for multi-user BasicAuth background sync
Previously, the multi-user BasicAuth mode attempted to retrieve app passwords
via OAuth client_credentials grant, which Nextcloud OIDC doesn't support.

This fix implements local storage for app passwords:
- Add app_passwords table via Alembic migration (002)
- Add store/get/delete methods to RefreshTokenStorage
- Add management API endpoints for app password provisioning:
  - POST /api/v1/users/{user_id}/app-password
  - GET /api/v1/users/{user_id}/app-password
  - DELETE /api/v1/users/{user_id}/app-password
- Update oauth_sync.py to read from local storage
- Update Astrolabe to send app passwords to MCP server after validation
- Add app-hook to configure mcp_server_url in Nextcloud

The flow is now:
1. User creates app password in Nextcloud Security settings
2. User enters it in Astrolabe Personal Settings
3. Astrolabe validates against Nextcloud, then sends to MCP server
4. MCP server stores encrypted app password locally
5. Background sync uses locally stored password

Chris CoutinhoandClaude Opus 4.5 804480836e fix(auth): Skip issuer validation for management API tokens
Fixes NC PHP app (Astrolabe) OAuth integration by making token validation
more lenient for management API access.

Problem:
- Astrolabe calls Nextcloud OIDC token endpoint via internal URL (http://localhost)
- Tokens are issued with iss: http://localhost (internal)
- MCP server expects iss: http://localhost:8080 (external)
- Token validation failed with "Invalid issuer"

Solution:
- Add skip_issuer_check parameter to _verify_jwt_signature()
- verify_token_for_management_api() now skips both audience and issuer checks
- Security maintained: signature still verified, authorization checked by API

Also includes related fixes from previous session:
- Update test selectors for Vue 3 UI ("Enable Semantic Search")
- Fix OIDC discovery URL transformation in OAuthController.php
- Add overwrite.cli.url to setup hook for proper external URLs

Chris CoutinhoandClaude Sonnet 4.5 4a5766b84e feat(config): enable DCR for multi-user BasicAuth with offline access
Allows multi-user BasicAuth mode to use Dynamic Client Registration (DCR)
for OAuth credentials when ENABLE_OFFLINE_ACCESS is enabled, making it
consistent with OAuth modes and reducing configuration burden.

**Changes:**

Configuration Validation:
- Relaxed OAuth credential requirements for multi-user BasicAuth
- OAuth credentials now optional when offline access enabled
- Will use DCR as fallback if NEXTCLOUD_OIDC_CLIENT_ID/SECRET not set
- Updated validation to log info instead of error when DCR will be used

Startup Logic (app.py):
- Added DCR workflow for multi-user BasicAuth before uvicorn starts
- Creates oauth_context for management APIs when offline access enabled
- Allows Astrolabe to authenticate management API calls with OAuth
- DCR runs synchronously at same lifecycle point as OAuth modes
- Added traceback import for better error logging
- Fixed type assertions for nextcloud_host
- Fixed undefined variable references in vector sync logging

Management API:
- Improved auth mode detection using proper detect_auth_mode()
- Added auth_mode field to /status endpoint:
  * "basic" - Single-user BasicAuth
  * "multi_user_basic" - Multi-user BasicAuth
  * "oauth" - OAuth modes
  * "smithery" - Smithery stateless
- Added supports_app_passwords indicator for multi-user BasicAuth

Docker Compose:
- Updated mcp-multi-user-basic service configuration:
  * Enabled vector sync (VECTOR_SYNC_ENABLED=true)
  * Added ENABLE_OFFLINE_ACCESS=true for app password support
  * Added NEXTCLOUD_MCP_SERVER_URL for Astrolabe integration
  * Documented optional static OAuth credentials

Testing:
- Updated test_config_validators.py to expect DCR fallback
- Enhanced configure_astrolabe_for_mcp_server fixture with verification
- Added debug logging to test_users_setup fixture

**Workflow:**
1. User configures ENABLE_OFFLINE_ACCESS=true
2. Server checks for static NEXTCLOUD_OIDC_CLIENT_ID/SECRET
3. If not found, performs DCR before uvicorn starts
4. DCR registers client with Nextcloud OIDC provider
5. OAuth credentials used for Astrolabe management API auth
6. Background sync can retrieve user app passwords via Astrolabe

Chris CoutinhoandClaude Sonnet 4.5 3fa376905c feat: add Alembic database migration system
Implements Alembic for managing token storage database schema versions.
Migrations run automatically on startup with full backward compatibility.

**Changes:**
- Add Alembic dependency (1.14.0+) and SQLAlchemy (auto-installed)
- Create migration infrastructure in alembic/ directory
- Add initial migration (001) capturing current schema
- Modify RefreshTokenStorage.initialize() to run migrations via anyio
- Add CLI commands: db upgrade, current, history, downgrade, migrate
- Add comprehensive migration documentation

**Backward Compatibility:**
- Pre-Alembic databases automatically stamped with revision 001
- No schema changes for existing databases
- Automatic upgrade on first startup after update

**Migration Strategy:**
Three scenarios handled:
1. New database → Run migrations from scratch
2. Pre-Alembic database → Stamp with 001 (no changes)
3. Alembic-managed → Upgrade to latest

**Architecture:**
- Uses anyio.to_thread.run_sync() for structured concurrency
- Alembic env.py runs with anyio.run() in worker thread
- SQLite-friendly migration patterns documented
- No ThreadPoolExecutor needed (anyio handles it)

**CLI Usage:**
```bash
nextcloud-mcp-server db upgrade    # Upgrade to latest
nextcloud-mcp-server db current    # Show version
nextcloud-mcp-server db history    # View changelog
nextcloud-mcp-server db downgrade  # Rollback (with confirmation)
nextcloud-mcp-server db migrate "description"  # Create migration
```

**Testing:**
- All 13 webhook storage tests pass
- New/pre-Alembic database scenarios validated

Chris CoutinhoandClaude Sonnet 4.5 44391d3d1d fix: address critical code review issues (4 fixes)
This commit addresses 4 critical issues identified in code review:

1. **Token Rotation Race Condition** (token_broker.py)
   - Added per-user locking mechanism to prevent concurrent refresh token corruption
   - Implemented double-check pattern for cache after acquiring lock
   - Users can now safely refresh concurrently without token desync

2. **Hardcoded OAuth Client ID** (PHP files)
   - Made client ID configurable via `astroglobe_client_id` in system config
   - Updated McpServerClient to provide getClientId() method
   - Injected McpServerClient into IdpTokenRefresher and OAuthController
   - Updated admin settings UI to display client ID configuration status
   - App gracefully handles missing client ID with warnings in admin UI

3. **Missing Cache Invalidation** (management.py:revoke_user_access)
   - Added cache.invalidate() call when revoking user access
   - Ensures both storage AND cache are cleared atomically
   - Prevents stale cached tokens from being used after revocation

4. **Error Message Exposure** (management.py)
   - Created _sanitize_error_for_client() helper function
   - Updated all error handlers to log detailed errors internally
   - Returns generic messages to clients to prevent information leakage
   - Protects against exposing database paths, API URLs, tokens, etc.

All changes are backward compatible and preserve existing functionality.

Chris CoutinhoandClaude Sonnet 4.5 85db90a2df feat(search): add file_path metadata and chunk offsets to search results
Changes:
- Add file_path to metadata in semantic and BM25 hybrid search algorithms
  for PDF viewer integration (search/semantic.py:161-163, search/bm25_hybrid.py:230-232)
- Include chunk_start_offset, chunk_end_offset, page_number, and page_count
  in search results for rich chunk display (api/management.py:981-1004)
- Add point_id field to SearchResult for batch retrieval (models/semantic.py)
- Fix type narrowing for chunk context API parameters (api/management.py:1102-1111)
- Fix None-safety in doc_types discovery (search/algorithms.py:114)

This enables the Astroglobe UI to display PDF pages at the correct
location for matched chunks.

Chris CoutinhoandClaude Sonnet 4.5 73783b85d5 feat(astrolabe): use proper icons and thumbnails in unified search
Improve search result display to match Nextcloud's native search providers by using mimetype-specific icons and preview thumbnails.

**File Results:**
- Use preview thumbnails for images/PDFs (core.Preview API)
- Use mimetype-specific icon classes (icon-pdf, icon-text, icon-image, etc.)
- Detect folders and use icon-folder appropriately

**Other Document Types:**
- Notes: icon-notes
- Deck Cards: icon-deck
- Calendar: icon-calendar
- News: icon-rss
- Contacts: icon-contacts

**API Changes:**
- Management API now includes mime_type in search results
- SemanticSearchProvider uses IMimeTypeDetector and IPreview services

This makes Astroglobe search results visually consistent with Files, Notes, and other native providers.

Chris CoutinhoandClaude Opus 4.5 97b48ca3dd feat(astrolabe): add 3D PCA visualization for semantic search
- Add Plotly.js 3D scatter plot showing search results in PCA space
- Create shared visualization.py module to avoid code duplication
- Pass include_pca parameter through API chain to enable coordinates
- Fix OAuth redirects to use /settings/user/astroglobe

The visualization shows document embeddings projected to 3D via PCA,
with the query point highlighted in red. Uses Viridis colorscale
for score visualization, matching the existing vector-viz page.
