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

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

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

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

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

Closes round-4 review feedback on PR #773.

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

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

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

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

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

Chris CoutinhoandClaude Opus 4.7 80b27b1bc6 refactor(vector): address PR #775 review — drop unused payload key, fix resource leaks
- Drop chunk_bbox_page from Qdrant payload — viz endpoints never read it
  (page_number is the canonical PDF page field).
- Bump upsert BATCH_SIZE 10 → 100 now that payloads no longer carry PNGs.
- compute_chunk_bboxes_batch: move doc.close() into finally, replace
  unused stored_page_num with _.
- purge_page_images.py: switch to anyio.run() per project convention,
  and wrap AsyncQdrantClient in try/finally so the aiohttp session is
  always closed (the class doesn't implement async-context-manager).
- Decorate new bbox unit tests with @pytest.mark.unit so they run under
  the fast-feedback selector.

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

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

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

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

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

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

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

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

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

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

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

This change:

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

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

Chris CoutinhoandClaude Opus 4.7 20f1770794 refactor(providers): address PR #772 review round 2 — guard, naming, docs, tests
- _retry.py: replace `assert last_error is not None` with explicit
  `if last_error is None: raise RuntimeError(...)` so the original
  rate-limit error is preserved under `python -O`.
- openai.py: drop the `_retry_factory` alias chain; rename the bound
  decorator to `_retry_429` to match the pattern in mistral.py.
- mistral.py: comment the imports so future reviewers understand why
  `from mistralai.client import …` is the canonical path on 2.x (no
  top-level `__init__.py`; no `mistralai.models` subpackage either).
- docs/configuration.md: add `OPENAI_GENERATION_MODEL` and
  `OLLAMA_GENERATION_MODEL` rows to the env-var reference table.
- test_mistral.py: add direct unit test for the `_is_rate_limit`
  predicate (429 → True, 500 → False, missing-attr → False).
- test_registry.py: stub `mistralai.client.Mistral` in the registry
  picker test, mirroring the Ollama sibling, so the test doesn't

Chris CoutinhoandClaude Opus 4.7 e360a7782b refactor(providers): address PR #772 review — shared retry, cleaner imports, no-op close
Addresses the Claude Code review on PR #772 plus the SonarCloud S1192 finding:

- Extract `retry_on_rate_limit` into `nextcloud_mcp_server/providers/_retry.py`
  as a parametric decorator. OpenAI and Mistral now share the same backoff
  loop; future providers can reuse it without copy-paste.
- New `tests/unit/providers/test_retry.py` covers the decorator: 429 retry +
  success, non-429 immediate re-raise, MAX_RETRIES exhaustion, default
  predicate, and unrelated exception passthrough.
- Tighten Mistral SDK import to `from mistralai.client.errors import SDKError`
  (the canonical sub-path; the reviewer's `from mistralai.models import
  SDKError` does not exist in mistralai 2.4.5).
- Replace `MistralProvider.close()`'s direct `__aexit__` call with a no-op +
  comment — the Speakeasy-generated client has no public close hook and the
  underlying httpx client is closed by GC.
- Extract the duplicated "Embedding not supported" message to a module-level
  constant (SonarCloud S1192).
- Align `Settings.get_embedding_model_name()` Bedrock check with the registry
  by also considering `bedrock_generation_model`.
- Add the `mock_mistral_client` fixture to
  `test_mistral_no_embeddings_disabled` for parity with the rest of the file.

Chris CoutinhoandClaude Opus 4.7 3268a13d11 feat(providers): add Mistral embedding provider, route registry through dynaconf
Adds a hosted Mistral embedding option (mistral-embed, 1024-dim) alongside
the existing Bedrock / OpenAI / Ollama / Simple providers. Implementation
mirrors OpenAIProvider: lazy dimension detection with a known-models lookup,
chunked batch requests, defensive index sort, and a 429-aware retry decorator.

In the same change, ProviderRegistry switches from os.getenv to the
dynaconf-backed Settings dataclass so all five providers share a single
configuration path. config.py gains the previously-uncovered Bedrock keys,
the new Mistral keys, the missing OPENAI_GENERATION_MODEL /
OLLAMA_GENERATION_MODEL, and SIMPLE_EMBEDDING_DIMENSION.

Auto-detection priority: Bedrock → OpenAI → Mistral → Ollama → Simple.

Chris CoutinhoandClaude Opus 4.7 e9e6bcc60a fix(webdav): include fileid in find_by_type SEARCH + address PR #765 review
The default property set in `search_files` omits `<oc:fileid>`, so
`find_by_type` returned descendant dicts with no `file_id` — which
`NextcloudClient.find_files_by_tag` then silently dropped via its
dedup-by-id guard. Net effect: tag-on-folder produced zero expanded
descendants in CI (single-user / nc31, nc32). Mirrors the explicit
property list already used in `WebDAVClient.find_by_tag`.

Also addresses three nits from the PR #765 bot review:
- trim multi-paragraph docstring on `_normalise_search_result`
- trim multi-line docstring on `find_files_by_tag`
- match `is not None` ID-extraction pattern in the descendant loop

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

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

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

Chris CoutinhoandClaude Opus 4.7 2ee4d03e3f fix(webdav): address PR #764 review round 3
Three important issues raised by the latest review on the
get_tag_by_name and get_files_by_tag methods:

1. Add explicit response.raise_for_status() after _make_request in both
   methods. _make_request already raises HTTPStatusError on non-2xx so
   the calls are redundant in practice, but keeping them visible at the
   call site makes the contract self-documenting and prevents a future
   refactor from silently feeding an error body into ET.fromstring.

2. Replace href_path.replace(webdav_prefix, "/") with a startswith +
   slice. str.replace strips every occurrence of the prefix; while no
   real Nextcloud path embeds the prefix mid-string, the fix removes
   the theoretical exposure and matches the pattern used elsewhere in
   the file.

3. Add Content-Type: text/xml to the systemtags PROPFIND headers.
   Other PROPFIND-with-body calls in this file (list_directory line
   240, list_attachments line 1041) include it; the systemtags PROPFIND
   was the only outlier. Same header added to the systemtag REPORT for
   symmetry.

No test changes — the existing get_files_by_tag mock test continues to
pass (the mock response yields valid XML so raise_for_status is a
no-op, and the user-relative path comparison is unaffected by the
prefix-strip swap on a non-adversarial path).

Chris CoutinhoandClaude Opus 4.7 35abfb2e3a fix(webdav): drop anyio.Lock and add integration tests for tag exclusion
Addresses two points from the latest PR #764 review:

1. The anyio.Lock in get_excluded_file_paths bought nothing under
   anyio's cooperative multitasking model (single-threaded between
   awaits, raw set mutations are already safe). _resolve_one_tag now
   builds a local set of paths and appends it to a shared list — list
   append between awaits is safe without a lock — and the caller
   merges via set().union(*results) after the task group completes.
   This removes the cognitive overhead the reviewer flagged without
   changing the public API.

2. Adds tests/integration/test_tag_exclusion.py exercising the
   resolution pipeline end-to-end against a real Nextcloud instance:
   creates a system tag, tags a real file and a real directory,
   verifies get_excluded_file_paths resolves both via real PROPFIND +
   REPORT calls, and verifies is_path_excluded correctly classifies
   exact matches, descendants of tagged directories, and unrelated
   paths. Includes the disabled-feature short-circuit case.

Cleanup runs in reverse order (untag, delete files); per-run uuid
suffix avoids cross-run interference.

Chris CoutinhoandClaude Opus 4.7 d179ca8c8b fix(webdav): address PR #764 review round 2
Addresses the four points raised in the automated review on PR #764:

1. Scope guards on the four search tools (search_files, find_by_name,
   find_by_type, list_favorites) so an excluded `scope` raises ToolError
   instead of silently returning an empty result. Previously an LLM
   could probe the asymmetry between list_directory (raises) and the
   search tools (silent) to infer that an excluded directory exists.
   The 4 search tools now mirror the early-guard pattern from
   list_directory and avoid an unnecessary upstream query for known-
   excluded scopes.

2. Concurrent per-tag resolution in get_excluded_file_paths via
   anyio.create_task_group(). Previously the 2N network calls (1
   PROPFIND + 1 REPORT per tag) ran serially. Per-tag fail-open
   behaviour is preserved by extracting _resolve_one_tag, which
   swallows its own exceptions so a single tag failure does not abort
   the surrounding task group.

3. WebDAVClient.get_tag_by_name and get_files_by_tag now route through
   _make_request, inheriting the @retry_on_429 decorator. Previously
   they bypassed it; with tag exclusion invoked on every WebDAV tool
   call, a transient 429 from the systemtags endpoint was hitting the
   fail-open path instead of being transparently retried.

4. Test coverage: 6 new tests in test_webdav_tools_exclusion.py (4
   scope-guard, 2 missing filter tests for find_by_type and
   list_favorites) and 2 new tests in test_tag_exclusion.py (a
   concurrency proof using an event-barrier that would deadlock under
   sequential execution, and a fail-open-under-task-group test with
   order-independent side_effect callables).

Chris CoutinhoandClaude Opus 4.7 a6c188abbb fix(webdav): address PR #764 review
Six findings raised in the PR review:

🔴 Blocking
- Fail-open on tag-resolution errors. get_excluded_file_paths now
  wraps each tag's get_tag_by_name and get_files_by_tag call in
  try/except; failures log a warning and the tag is skipped, rather
  than propagating to the caller and disabling all WebDAV tools when
  the systemtags endpoint is degraded. Documented in the docstring as
  the intended fail-open behaviour (threat model is preventing
  accidental exfiltration, not surviving server compromise).

🟡 Important
- nc_webdav_list_directory now raises ToolError when the listed path
  itself is tagged, instead of silently returning an empty listing
  after a wasted PROPFIND. Behaviour now mirrors the mutating tools.
- Destination error messages in move/copy/create_directory said "is
  inside" but is_path_excluded matches exact paths too. Reworded to
  "is or is inside".

🟢 Nits
- get_excluded_file_paths log message clarified: N counts
  directly-tagged paths, not total descendants.
- Test isolation: tests/unit/conftest.py already has an autouse
  _reload_dynaconf_after_test fixture that handles teardown. Removed
  the redundant module-local fixture I had drafted; documented the
  reliance in the module docstring instead.
- Added tests/unit/test_webdav_tools_exclusion.py: 12 server-layer
  tests that register the WebDAV tools on a fresh FastMCP and invoke
  each tool's underlying function with a mocked excluded set, asserting
  ToolError is raised / results filtered as expected. Catches future
  guard-integration regressions (e.g. wrong argument order).

Also added two unit tests for the new fail-open behaviour.

Chris CoutinhoandClaude Opus 4.7 22ed9e99a0 feat(webdav): add tag-based file exclusion (#710)
Hide sensitive files/folders from the WebDAV MCP tool surface by
tagging them with a configured Nextcloud system tag. Defence-in-depth
control for users who connect LLMs to accounts holding contracts,
medical records, credentials, etc.

A new EXCLUDED_TAGS env var (comma-separated tag names, empty by
default) gates an exclusion layer that runs at the start of every
WebDAV tool call: tag names are resolved to tag IDs, those IDs are
expanded to the set of tagged paths, then listings/searches are
filtered and read/write/delete/move/copy operations on excluded paths
raise ToolError. Tagged folders exclude their descendants via prefix
match. Empty EXCLUDED_TAGS disables the feature entirely.

The threat model is preventing accidental data exfiltration via the
LLM tool surface — not hiding files from a determined operator. The
docs explicitly recommend creating exclusion tags with
user_assignable=false so the credentials the MCP server uses cannot
remove the tag.

Implementation:

- config.py: add `excluded_tags` to _DEFAULTS, Settings, and the
  _field_map alongside other comma-separated env vars.
- client/webdav.py: get_files_by_tag now requests <d:resourcetype/>
  and surfaces is_directory so tagged directories can recursively
  exclude descendants.
- server/tag_exclusion.py (new): get_excluded_tag_names,
  get_excluded_file_paths, is_path_excluded.
- server/webdav.py: exclusion guards in all 11 WebDAV tools;
  read/write/create/delete/move/copy raise ToolError, list/search
  tools silently filter excluded entries. Existing f-string log
  calls converted to lazy %-style.
- tests: 17 new unit tests covering path-matching edge cases
  (shared-prefix non-match, descendants of excluded dirs), tag-name
  parsing, and get_excluded_file_paths with mocked WebDAV; 1 new
  client test asserting <d:resourcetype/> -> is_directory parsing.
- docs/configuration.md: new "Tag-Based File Exclusion" section with
  per-tool effect table, security guidance, and per-call cost note.
- README.md: feature mention under Key Features.

Closes #710.

Chris CoutinhoandClaude Opus 4.7 b3a7587f1a fix(webhooks): use HTTP 428 instead of 412 for unprovisioned users
428 (Precondition Required, RFC 6585) is the correct semantic — the
request requires the client to complete a prerequisite step (Login Flow
v2 provisioning) before retrying. 412 (Precondition Failed) is for
header-based preconditions like ETags / If-Match.

No behavior change beyond the status code; same JSON payload.

Chris CoutinhoandClaude Opus 4.7 a0e484d95b fix(webhooks): use app-password basic auth for NC API calls
The webhook API endpoints in api/webhooks.py forwarded the inbound MCP
OAuth bearer token directly to Nextcloud as the Authorization header.
Per ADR-022 / docs/login-flow-v2.md the data leg from MCP server to
Nextcloud must use HTTP Basic Auth with the user's stored Login Flow v2
app password — bearer-forwarding requires upstream user_oidc patches that
were never merged and is incompatible with admin endpoints gated by
@PasswordConfirmationRequired (e.g. webhook_listeners/api/v1/webhooks,
which 401s).

PR #760 papered over the symptom for /api/v1/apps by switching to the
permissive /cloud/capabilities endpoint, but the same architectural
mistake remained on list_webhooks / create_webhook / delete_webhook,
which still 500'd on the astrolabe admin UI's preset page.

Changes:
- New helper api/_auth.py:get_basic_auth_for_user(user_id) reads the
  user's app password from encrypted storage and returns
  (username, app_password). Mirrors context.py:_get_client_from_login_flow
  but is callable from Starlette routes (no MCP Context required).
- All four endpoints in api/webhooks.py now use httpx.BasicAuth instead
  of forwarding the OAuth bearer; ProvisioningRequiredError is mapped to
  HTTP 412 so callers can render a "complete provisioning" CTA rather
  than receiving an opaque 500.
- Outbound NC requests now identify the user by the username recorded at
  Login Flow v2 provisioning time (which may differ from the IdP-issued
  user_id) — flowed into WebhooksClient and used for logging.

Tests:
- tests/unit/test_management_apps_endpoint.py: assertions updated to
  verify outbound NC request uses BasicAuth and carries no Authorization
  header. Replaced "missing-Authorization → 500" test with a
  ProvisioningRequiredError → 412 case.
- tests/unit/test_webhooks_api_auth.py (new): cross-endpoint coverage
  for list_webhooks, create_webhook, delete_webhook and the new helper —
  including 412 symmetry for all four endpoints.

Chris CoutinhoandClaude Opus 4.7 148ab8c117 fix(webhooks): use OCS v2 capabilities for /api/v1/apps
The Astrolabe webhooks UI hits /api/v1/apps on the MCP server, which
forwarded the OAuth bearer token to /ocs/v1.php/cloud/apps?filter=enabled.
That OCS endpoint is admin-only AND @PasswordConfirmationRequired —
neither requirement is satisfiable via an OAuth bearer token, so even an
admin user's token returns a silent 401 (no entry in nextcloud.log).

Switch to /ocs/v2.php/cloud/capabilities, which has no admin or password-
confirmation gate, accepts the existing bearer token, and returns a
capabilities map keyed by app id (notes, files, tables, forms, etc.).
This is sufficient for the webhook presets UI to gate available presets
against the running Nextcloud instance's enabled apps.

Bearer is preserved on the outbound call because anonymous capabilities
omits notes/tables/forms — only authenticated capabilities exposes them.

Tests:
- New unit test covers the regression (asserts /ocs/v2.php/cloud/capabilities
  is hit, NOT /cloud/apps), response parsing, sanitized error messages,
  and missing-config paths.
- New integration test under tests/server/login_flow/ drives a real
  OAuth flow against mcp-login-flow with a static OIDC client
  (nextcloudMcpServerUIPublicClient) and asserts /api/v1/apps returns 200
  with core/files in the response.

docker-compose.yml: aligns mcp-login-flow's ALLOWED_MGMT_CLIENT with
mcp-multi-user-basic so the same static-client test fixture works for both.

Follow-up to homelab-argocd #1608, which set ALLOWED_MGMT_CLIENT in
production but didn't unblock the webhooks flow.

Chris CoutinhoandClaude Opus 4.7 b875eaf069 fix(auth): address PR #758 round-7 medium/minor review
- Gate browser session creation on a successful refresh token. When the
  IdP returns no refresh token, SessionAuthBackend would silently reject
  every subsequent request and bounce the user back to /oauth/login in a
  loop. The callback now bails with a 400 + correlation ID + actionable
  hint about offline_access *before* writing browser_sessions or setting
  the cookie. Pinned by a new end-to-end unit test.
- Evict orphaned browser_sessions rows in SessionAuthBackend when the
  associated refresh token is gone, instead of letting them accumulate
  until TTL cleanup. Best-effort; deletion errors stay non-fatal.
- Demote identity-bearing logs in the Flow 2 OAuth callback (user_id,
  scopes, audience, expires_at) from INFO to DEBUG so they don't leak
  into multi-tenant log aggregation on every provision.

- Coerce refresh_expires_in to int before arithmetic in both callback
  paths so IdPs that serialize the field as a JSON string (e.g. AWS
  Cognito) don't trigger an unhandled TypeError 500.
- Drop the orphaned oauth_session row written by _check_logged_in. The
  canonical Flow 2 row is created by generate_oauth_url_for_flow2 keyed
  by `state`, which is what the unified callback looks up; the
  flow2_<hex> session_id was never matched and just churned the table
  for 10 minutes per call.
- Match delete_cookie attributes (httponly, secure, samesite) to the
  set_cookie call on logout so browsers reliably evict the cookie even
  on implementations that consider security flags during deletion.

Chris CoutinhoandClaude Opus 4.7 ec9b9b2a75 fix(auth): address PR #758 round-6 medium/low review
Five findings from the latest review on #758 (2 medium, 3 nit):

Medium:
- browser_oauth_routes.oauth_login_callback + oauth_routes.oauth_callback_nextcloud:
  fail closed with 400 when the oauth_session row is unknown/expired. Previously
  both callbacks fell through with code_verifier="" and expected_nonce=None,
  silently bypassing the PKCE + nonce protections introduced in earlier rounds.
  Symmetric unit tests pin both contracts.
- token_utils.verify_id_token: use secrets.compare_digest for the nonce check
  instead of short-circuit !=. Mirrors the sibling PKCE verifier comparison;
  closes the last secret-equality timing-side-channel surface in the auth path.

Nit:
- Tighten the comment at all 4 mcp_authorization_code/code_verifier store +
  retrieve sites so a future refactor sees the field reuse immediately
  (renaming the column requires a schema migration).
- _should_use_secure_cookies: explicit string normalisation instead of
  bool(settings.cookie_secure). Dynaconf normally coerces but tests / direct
  settings.set calls can leave the raw string in place — bool("false") is True.
  New parametrized unit tests cover the coercion matrix + http/https fallback.
- oauth_routes.py:591 f-string log converted to lazy %s formatting (folded into
  the Flow 2 callback rewrite).

Chris CoutinhoandClaude Opus 4.7 e2955e8246 fix(auth): address PR #758 round-5 medium/low review
Three findings from the latest review on #758 (1 medium, 2 low):

Medium:
- browser_oauth_routes.oauth_logout: move delete_browser_session into a
  finally block so an error from delete_refresh_token can no longer leave
  an orphan browser_sessions row. The orphan was not exploitable
  (SessionAuthBackend rejects sessions without a live refresh token), but
  it lingered until the hourly cleanup cron — a correctness gap. New
  regression test pins the fix.

Low:
- oauth_callback_nextcloud: drop redundant ``or None`` from
  ``expected_nonce=nonce``. ``nonce`` is already ``str | None`` and
  ``secrets.token_urlsafe`` never produces an empty string, so the
  coercion was a no-op that could mislead future readers into thinking
  empty-string was a valid skip-the-check path.
- storage.RefreshTokenStorage.initialize: fail fast at startup when
  SQLite < 3.35, since ``DELETE ... RETURNING`` (used in
  ``delete_browser_session``) needs that minimum. Ubuntu 20.04 ships
  3.31 and would otherwise hit OperationalError on every logout.
  Prerequisite also documented in docs/installation.md.

Seven findings from the latest review on #758 (3 medium, 4 low/nit):

Medium:
- storage.py: replace 5 ``assert self.cipher is not None`` sites with
  explicit ``RuntimeError`` so missing TOKEN_ENCRYPTION_KEY can't silently
  become an AttributeError under ``python -O``
- session_backend.py: document the silent-invalidation invariant —
  refresh-token TTL expiry without explicit logout deliberately makes
  the browser session unusable; future readers must not relax it
- server/oauth_tools.py: drop user_id from the Flow 2 session_id
  identifier — use ``flow2_{secrets.token_hex(16)}`` so audit logs and
  DB rows don't carry user_id in the session_id field

Low / nit:
- token_utils.py: drop _fetch_locks dict entry in finally so a probed
  deployment can't grow the lock dict without bound; coalescing test
  now pins the invariant with len(_fetch_locks) == 0
- browser_oauth_routes.py: strip trailing slash from settings.nextcloud_host

- Flow 2 (oauth_authorize_nextcloud) now generates a nonce, stores it on
  the oauth_session row, forwards it to the IdP, and verifies it via
  expected_nonce in oauth_callback_nextcloud — closes the last replay-
  protection gap (round-3 finding 1).
- _origin_matches_self fails closed when mcp_server_url is missing
  instead of allowing the logout, and the diagnostic log is promoted
  from warning to error so the misconfiguration is monitorable
  (round-3 finding 2). New regression test pins the new behaviour.
- The five user_id-accepting helpers in oauth_tools.py (get_provisioning_status,
  provision_nextcloud_access, revoke_nextcloud_access, check_provisioning_status,
  check_logged_in) are renamed with leading underscores to make the
  trust boundary structural rather than documentary
  (round-3 finding 3).
- create_browser_session and delete_browser_session now emit audit_log
  rows so session establishment / teardown match the pattern used by
  the rest of the security-relevant storage operations
  (round-3 nit 5). delete_browser_session selects user_id before delete
  so the audit row is attributable.
- oauth_login_callback no longer reflects raw IdP-error text or

  "internal error occurred" message + a correlation ID, with the
  detail logged server-side keyed by the same ID (round-3 nit 6).

Chris CoutinhoandClaude Opus 4.7 2ef4bfc4af fix(auth): fail closed on missing sub claim, delete Flow 2 callback session
Addresses the two remaining 🟡 findings from the PR #758 follow-up review:

  1. extract_user_id_from_token previously fell back to "default_user" when
     the verified access token had no sub claim. In a multi-tenant deployment
     a malformed IdP token could have bucketed every request under a single
     sentinel user, risking cross-tenant data exposure. The function now
     raises McpError on that branch; the BasicAuth no-token sentinel path is
     preserved.

  2. oauth_callback_nextcloud (Flow 2) read the PKCE code_verifier from
     oauth_sessions but never deleted the row, leaving the verifier valid for
     the full 10-minute TTL. The row is now deleted eagerly inside the same
     branch, mirroring oauth_login_callback in browser_oauth_routes.

Also wires TOKEN_ENCRYPTION_KEY through the docker-compose step in the CI
test workflow so the integration matrix can boot — every job had been
failing fast on the ${TOKEN_ENCRYPTION_KEY:?...} interpolation guard added
in PR #758 finding 5.

Tests pin both fixes (test_token_utils_user_id.py,
test_oauth_callback_session_cleanup.py).

- JWKS cache had no kid-miss refresh path (Medium): on IdP key
  rotation every login failed for up to _OIDC_CACHE_TTL. Evict
  and refetch once before raising, per OIDC core §10.1.1.
- _should_use_secure_cookies fell back to nextcloud_host scheme,
  but the cookie is issued by the MCP server. Switch to
  settings.nextcloud_mcp_server_url so split-scheme deployments
  get the right Secure flag.
- _origin_matches_self compared raw netloc strings, which include
  the port. Browsers omit default ports per RFC 6454 §6.2; an
  mcp_server_url like :443 falsely 403'd every legitimate logout.
  Normalise (scheme, host, port) tuples with default ports stripped.
- delete_oauth_session exists in storage.py — drop the stale
  "we don't have this method" comment and call it eagerly so
  replays can't be processed and the table doesn't accumulate
  completed-but-not-yet-expired browser-login rows.
- extract_user_id_from_token's unused ctx param renamed to _ctx
  to signal "intentionally unused" at the signature level.
- provisioning_decorator instantiated RefreshTokenStorage per
  call. Switch to get_shared_storage() for the lock-protected
  process-wide singleton.

Plus pre-push self-review catch: lazy-logging on the unchanged
except arm in session_backend.py.

Adds 5 regression tests:
  - JWKS rotation: success on refetch
  - JWKS rotation: still-missing-kid surfaces original error
  - JWKS rotation: network error during refresh wrapped as
    IdTokenVerificationError
  - default-port CSRF: explicit :443 in config + portless Origin
  - default-port CSRF: portless config + explicit :443 in Origin
  - scheme-mismatch CSRF: same host, different scheme rejected

Chris CoutinhoandClaude Opus 4.7 af25c281bf fix(auth): use Settings for OIDC env vars in token revocation helper
After merging master, _should_use_secure_cookies was refactored to read
from Settings instead of os.getenv, which dropped `import os` from
browser_oauth_routes.py — leaving _revoke_refresh_token_at_idp's four
remaining os.getenv() calls undefined (CI ruff F821).

Migrate the helper to the same Settings-based pattern:
  - oidc_discovery_url     → settings.oidc_discovery_url
  - OIDC_CLIENT_ID         → settings.oidc_client_id
  - OIDC_CLIENT_SECRET     → settings.oidc_client_secret
  - NEXTCLOUD_HOST         → settings.nextcloud_host

Drive-by: the previous fallback read OIDC_CLIENT_ID, but the canonical
env var per env.sample / docker-compose is NEXTCLOUD_OIDC_CLIENT_ID.
The Settings layer handles this mapping via dynaconf, so the corrected
name is now used automatically.

Chris CoutinhoandClaude Opus 4.7 931ee602eb fix(auth): address PR #758 review — XSS, CSRF, open redirect, JWKS cache
Addresses all 9 findings from the review on PR #758:

Blocking:
- _revoke_refresh_token_at_idp now reads config from oauth_ctx["config"]
  (the production-shaped nested dict). Previously read flat keys, causing
  IdP revocation to silently no-op in production. Test fixtures rebuilt
  to the realistic nested shape so the bug can't regress unnoticed.
- HTML error responses in oauth_login_callback now wrap IdP-controlled
  error_body, str(e), and the attacker-controlled error/error_description
  query params in html_escape. New test_browser_oauth_xss.py pins this.

Important:
- New _safe_next_url helper validates the ?next= query param at write
  time (oauth_login), in oauth_logout, and on read from the session row
  in oauth_login_callback. Blocks https://, // (protocol-relative), and
  CRLF/whitespace injection.
- verify_id_token now caches discovery + JWKS (5-min TTL) using the
  same pattern as oauth_routes._get_cached_discovery. New caching
  regression test pins to one fetch per URL across multiple calls.
- /oauth/logout is now POST-only at the route layer (defeats passive
  CSRF via <img src>). oauth_logout also validates Origin/Referer
  against the configured mcp_server_url. Logout UI in user_info.html
  converted from <a href> to <form method="post">.
- New storage.cleanup_expired_browser_sessions() called from the hourly
  cleanup loop in app.py — previously these rows accumulated for users
  who never explicitly logged out.

Nits:
- Demoted INFO logs that leaked oauth_config.keys() / client_id /
  token-storage state to DEBUG. Operator-relevant outcome lines
  (login successful, refresh token stored, logged out) stay INFO.
- verify_id_token algorithms widened to RS256, PS256, ES256 — covers
  Azure AD (PS256) and Cognito/some Keycloak realms (ES256). Symmetric
  and "none" remain off the allowlist.
- Migrated all Optional[X] usages in auth/storage.py to X | None per
  CLAUDE.md.

Breaking change: GET /oauth/logout now returns 405. The in-tree logout
UI was migrated to a POST form; any external bookmark or curl-based
caller that relied on GET will need to switch.

Chris CoutinhoandClaude Opus 4.7 ce80a36877 fix(auth): address PR #757 round-3 review feedback
Three review items from the third-round review on PR #757:

- scope_authorization: split the combined logger.warning(error_msg) in
  the require_scopes decorator's missing-app-password branch into two
  lazy %-style logger calls (one per branch), keeping the f-string
  error_msg for the exception only. The else branch also logs the
  elicit_result for diagnostics. Bypassing lazy %-interpolation in
  security-sensitive code formatted the message regardless of log level
  and matched the repo-wide lazy-logging preference; the new code now
  conforms.
- config + browser_oauth_routes: wire COOKIE_SECURE through Settings
  (cookie_secure: bool | None = None) so _should_use_secure_cookies()
  reads it via get_settings() rather than os.getenv. Completes the
  consolidation pass that touched this file in commit 7464340 and
  removes the last raw os.getenv from browser_oauth_routes.py
  (import os dropped). Dynaconf auto-coerces "true"/"false" → bool;
  "1"/"0" arrive as int and are normalised by an explicit bool() at
  the consumer.
- elicitation: clarify the _astrolabe_settings_url docstring to call
  out that the empty-string case is also a None-return path (matches
  the existing `if not base:` guard).

Chris CoutinhoandClaude Opus 4.7 15dbb26349 fix(auth): harden OAuth/session for hosted multi-tenant deployment (#626)
Pre-launch hardening for the hosted Astrolabe Cloud offering. Addresses
all five findings raised in #626 (Tim Kaufmann, code review of v0.65.0).
Re-verified against master before fixing.

Finding 3 (LLM-controllable user_id) — drop user_id from the public
signatures of provision_nextcloud_access, revoke_nextcloud_access,
check_provisioning_status, check_logged_in. Tool wrappers now always
derive identity from the verified AccessToken; user_id is no longer
accepted as MCP input. Adds parameterized CI-guard test that locks the
schema.

Finding 2 (predictable session cookie) — replace mcp_session=<user_id>
cookie with a cryptographically random session_id mapped server-side
(new browser_sessions table, alembic 005). Cookie value is opaque,
expires, revocable. SessionAuthBackend looks up user_id via the new
mapping and additionally requires a refresh token to fail closed.

Finding 4 (logout doesn't revoke refresh token) — oauth_logout now
calls the IdP revocation_endpoint (RFC 7009) when advertised, deletes
the stored refresh token regardless, and clears the browser_sessions
row. Cleanup is best-effort: logout always 302s.

Finding 1 (unverified ID token decodes) — verify_id_token helper does
JWKS signature + issuer + audience + exp + nonce checks per OIDC core
3.1.3.7. Used by both OAuth callback handlers (browser + MCP). Removes
the four "verify_signature: False" decodes that previously trusted IdP
claims unconditionally. Drops dead-code _validate_token_audience in
token_broker. Refactors token_utils + provisioning_decorator to read
user_id from the verified AccessToken instead of re-decoding the JWT.

Finding 5 (hardcoded Fernet keys in docker-compose.yml) — replace the
three inline TOKEN_ENCRYPTION_KEY values with required env var
interpolation; document in env.sample.

Test coverage: 4 new unit test modules (signature pinning, browser
sessions, ID-token verification, logout + revoke + session backend).
693 unit tests pass; ruff/format/ty clean.

Migration note: existing browser admin-UI sessions become invalid on
rollout (cookies are looked up against the new browser_sessions table,
which starts empty). Users re-login. MCP API access is unaffected.

Tracked on Astrolabe Cloud POC board card #37.

Chris CoutinhoandClaude Opus 4.7 f31d0544b7 fix(auth): invalidate scope cache on web/REST provisioning paths
The elicitation flow points users to the Astrolabe web route or the
BasicAuth REST endpoint to provision their app password. Both paths
stored the password without clearing the in-process scope cache, so a
user who provisioned through them would keep hitting
ProvisioningRequiredError for up to _SCOPE_CACHE_TTL (5 min) afterwards.

Add invalidate_scope_cache(user_id) to both write-paths (matching the
existing pattern in nc_auth_check_status), correct the now-misleading
comment in scope_authorization.py to name all three invalidation paths,
and add a one-line hint above the first elicitation patch in the test
file so future authors don't "fix" the patch target to the wrong module.

Addresses PR #757 round-3 review feedback.

Chris CoutinhoandClaude Opus 4.7 7464340763 fix(auth): address PR #757 round-2 review feedback
Four review items from the second-round review on PR #757:

- scope_authorization: broaden the post-elicit retry message to acknowledge
  the 5-minute scope-cache TTL — if the LFv2 poller is still in-flight at
  acknowledge-time, the immediate retry can still hit a stale cache.
- elicitation: extract a shared `_run_elicit(ctx, message, schema, *,
  log_label)` helper so `present_login_url` and
  `present_provisioning_required` no longer duplicate the
  hasattr-guard / try-NotImplementedError / try-Exception fallback block.
  The data-acknowledged warning specific to login-flow stays in
  `present_login_url` so behaviour is preserved exactly.
- elicitation: detect missing http:// / https:// scheme in
  `_astrolabe_settings_url`, log a warning, and return None — caller
  renders the safe tool-only fallback instead of producing a broken link.
  New unit test locks this in.
- browser_oauth_routes: replace the stray
  `os.getenv(\"NEXTCLOUD_HOST\")` in `_should_use_secure_cookies` with
  `get_settings().nextcloud_host` for consistency with the rest of the
  file (PR #757 review nit).
