Remaining items from the PR #831 Claude review:
- processor span symmetry: add "vector_sync.total_chars" to the sparse
embedding span (already on the dense span) and drop the redundant
"embedding.batch_size" attribute from both spans — it always equalled
vector_sync.chunk_count and would mislead once batching is split.
- metrics: document the deliberate "throughput counts only on full success"
contract in record_document_parse (partial extractions flagged
success=False are counted as a parse-error but never inflate
pages/chars/bytes throughput).
- config: extract _detect_base_provider() -> (family, model) as the single
source of truth for the provider-detection priority chain, shared by
get_embedding_model_name() and get_embedding_provider_family(). Preserves
the intentional gateway asymmetry (only the family method short-circuits).
- base.py: Optional[...] -> PEP 604 `... | None`; drop now-unused import.
Behavior unchanged (get_embedding_* outputs covered by test_config.py).

Add a path_prefix filter to semantic search, honoured on both the MCP tool and
the dense-only visualization/API paths through the shared filter contract.
- build_base_filter_conditions: append FieldCondition(file_path,
MatchText(path_prefix)) when set. file_path is only on doc_type == "file"
points, so a non-empty path_prefix implicitly restricts to files.
- Promote path_prefix to an explicit keyword param on the SearchAlgorithm ABC
and both algorithms; thread it through nc_semantic_search (blank ⇒ no filter),
the /api/v1 search endpoints, and the viz route.
- Add a file_path TEXT payload index to _PAYLOAD_INDEX_FIELDS (no content
re-index; idempotent startup migration). MatchText tokenizes on server Qdrant
and matches by substring on local/embedded qdrant-client — both serve folder
scoping.
- Update ADR-027 (Phase 2 implemented; readiness table; semantics note). Tests.

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.

Address the two important findings from the claude bot's latest re-review:
- _verify_files: skip get_excluded_file_paths entirely when the tag REPORT
returns no files. An empty `tagged` yields an empty `tagged_ids` regardless
of exclusions, so the lookup's 2xlen(EXCLUDED_TAGS) WebDAV fan-out is wasted
work in the common "this tag matched nothing" case. The per-result loop still
runs, so malformed doc_ids are still kept (fail-open) — pinned by a new test
(test_verify_files_empty_tag_set_skips_exclusion_lookup), which also asserts
the exclusion lookup is never awaited.
- Rewrite the semaphore comment: it claimed "the slot bounds them", but the slot
only caps concurrent *searches* — get_excluded_file_paths internally spawns a
task group issuing 2xlen(EXCLUDED_TAGS) concurrent WebDAV calls, so live
Nextcloud connections can exceed VERIFICATION_CONCURRENCY. Comment now says so
and points at configuration.md.
The third 🟡 (sequential dir expansion in find_files_by_tag) is pre-existing and
flagged by the reviewer as a follow-up, not part of this PR.

Resolve the blocking + important findings from the claude bot's re-review:
- test (blocking): pin the file verifier's fail-open contract for definitive
403/404 on the tag REPORT, not just transient 503/429. A disabled systemtags
endpoint commonly 403s; unlike the per-access verifiers (where 403/404 = drop),
the batch file verifier must keep all results since the whole set hinges on one
REPORT. Adds _http_error(403)/_http_error(404) to
test_verify_files_tag_fetch_failure_keeps_all and documents the asymmetry.
- docs (important): migration caveat — if vector-index was created as
user_visible=False (manual occ tag:add, or pre-release), an owner's tag won't
surface in a recipient's REPORT and shared-file results are silently dropped
after upgrade. Note that the MCP server's get_or_create_tag defaults to
user_visible=True, and how to verify/fix an existing tag.
- docs (important): note the file verifier's latency scales with both the
Depth:infinity folder expansion and the EXCLUDED_TAGS lookup (~2 WebDAV calls
per excluded tag, fanned out under one slot); suggest lowering
VERIFICATION_CONCURRENCY for large excluded-tag lists / deeply tagged trees.

Resolve the latest PR-review comment on the verify-on-read tag-gate work:
- tests: stringify note IDs in test_verify_on_read.py so SearchResult.id
matches production (scanner stringifies all IDs on write) — helper and the
keeps/deleted/mixed/dedupe assertions (blocking).
- tests: make the unshared-file negative control a PDF so the drop is
unambiguously "unshared", not a mime_type_filter mismatch.
- config: add Validator("VECTOR_SYNC_PDF_TAG", len_min=1) — an empty tag name
would make find_files_by_tag("") misbehave in the verifier and scanner.
- verification: correct the _verify_files comment — two batch fetches (tag
REPORT + EXCLUDED_TAGS lookup) are held under one semaphore slot; the
pure-Python intersection runs outside it.
- tests: de-duplicate the minimal-PDF constant into a shared PDF_BYTES in
tests/integration/conftest.py, imported by both integration modules.
Verified: ruff/format/ty/unit all green; the two integration modules
(10 tests) pass against a local Nextcloud (app-only, no MCP profile needed).

Verify-on-read only checked file *accessibility* (file_accessible_by_id),
never tag membership, so a file removed from the `vector-index` tag (but
still readable) kept surfacing in semantic search, and stale points only
got evicted when they happened to rank in a search's top-K.
Rework `_verify_files` to gate on current `vector-index` tag membership via
a single batch `find_files_by_tag(tag, mime_type_filter="application/pdf")`
REPORT per search (plus a one-shot EXCLUDED_TAGS lookup for exclusion-wins
parity) — exactly what the scanner indexes. A file is kept iff it is in that
set, so untagged / deleted / excluded files drop out immediately and the
existing eviction wiring reclaims their Qdrant points. The gate is strict
for all file results, own and shared. Mirrors the batch-fetch-and-intersect
shape of `_verify_news_items` (one semaphore slot, fail-open on fetch error,
malformed-id keep).
- Promote the tag name to a `vector_sync_pdf_tag` Settings field (dynaconf
env mapping VECTOR_SYNC_PDF_TAG) used by both scanner and verifier;
drop the scanner's direct os.getenv.
- Expose `find_files_by_tag` on NextcloudClientProtocol.
- Rewrite the file-verifier unit tests (tagged/untagged/deleted/excluded/
fail-open/non-numeric); update the ACL + verify-on-read integration tests
to seed tagged PDFs.
- Amend ADR-019 and the configuration.md verify-on-read latency budget.

- Failed deletes no longer bump astrolabe_documents_indexed_total: the outer
except in process_document now gates doc_type on operation != "delete", so a
delete error is counted as processed-error but not as an indexing event.
Added test_failed_delete_is_processed_but_not_indexed.
- registry parse span: pass record_exception=True explicitly (matches
instrument_tool) and add a structured logger.warning on the parse-error path
(processor/tier/byte_size/duration_ms) for a Loki-aggregatable failed-parse
signal.
- test_error_does_not_increment_throughput: snapshot-before/delta pattern
instead of absolute 0.0 (counters are global singletons).
- config: document the deliberate gateway asymmetry between
get_embedding_model_name() (no gateway branch) and
get_embedding_provider_family() (short-circuits on gateway).
- Cleanup in touched scope: narrow `except (HTTPStatusError, Exception)` to
`except Exception` (drop now-unused import); convert registry signatures from
Optional[...] to `... | None`.

Reviewer findings:
- Fix double-count of exhausted-retry failures: the inner final-retry branch
and the outer except both recorded a processing error. Consolidate to the
outer handler (single call site); inner branch keeps only the Qdrant-upsert
error metric. Regression test added.
- Deletes are no longer counted as indexing events: the delete success path
drops doc_type so astrolabe_documents_indexed_total is not inflated.
Regression test added.
- Reuse the already-resolved `settings` in _index_document instead of a second
get_settings() call.
- Use explicit `> 0` guards in record_document_parse / record_embedding instead
of truthiness checks.
SonarCloud:
- S1244 (BUG): replace float `==` equality in metric tests with pytest.approx.
- S5332 (hotspot): use https in the gateway-URL test fixture.
- S1192: extract the repeated "vector_sync.chunk_count" span-attribute literal
into a module constant.
Review nit: move the duplicated `_sample` test helper into a shared
`metric_sample` fixture in tests/unit/conftest.py.

Make per-tier bottlenecks in the document-processing pipeline
(scan -> fetch -> parse -> chunk -> embed -> Qdrant upsert) visible via
metrics, traces, and structured logs. Today the document_processors layer
emits only a logger.info line: no metric, no span, and page counts live only
inside a log string. The single processing-duration histogram is unlabeled and
whole-document, so it cannot isolate parse vs embed vs upsert.
New astrolabe_* metric family (distinct from the mcp_* protocol metrics):
- astrolabe_document_parse_{duration_seconds,total} + pages/chars/bytes counters
recorded at the ProcessorRegistry.process() boundary (covers all current and
future processors uniformly)
- astrolabe_document_escalation_total (dormant; tiered-pipeline readiness)
- astrolabe_embedding_{duration_seconds,requests_total,chunks_total,chars_total}
- astrolabe_document_chunks_total, astrolabe_documents_indexed_total{source,status}
Tracing: new document_processor.parse child span + enriched embed/chunk span
attributes (provider/model/batch_size/chunk_count). Structured logs gain a
consistent field vocabulary (doc_id, doc_type, processor, tier, pages, chars,
byte_size, chunks, duration_ms, status) so Loki can aggregate without regex.
Tier-readiness: processor/tier are labels from day one and a tier property is
added to DocumentProcessor, so adding docling/OCR/LLM tiers later is additive
(new label values, never new metrics). Tenant comes from the kube namespace
label; mime_type/model are span attributes only (cardinality). Existing
mcp_vector_sync_*/mcp_qdrant_* are left untouched.

- 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.

SonarCloud's python:S7632 parses the literal ``# NOSONAR`` token wherever it

comments describing them. Reword those comments to drop the inner ``#`` so the

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).

The new decomposition modules used `# NOSONAR: reason` (colon form), which
SonarCloud flags as a malformed suppression comment (python:S7632) and which
fails to suppress the intended issue. Switch to the repo's bare `# NOSONAR`
convention with the rationale in a comment above, matching config.py and
