Round-1 review nits. The constant now only gates the diagnostic `image_heavy`
flag (not routing), so the old name was misleading. Rename + reword its comment
to state the diagnostic-only intent. Also add a classify_pdf symmetry test
(`test_classify_pdf_image_heavy_clean_text_stays_fast`) pinning that a full-page
raster image with a clean text layer routes fast on the classify_pdf path too.

The tier-0 classifier escalated any page with raster-image coverage >=0.80 to
the OCR tier regardless of its text layer. On OHR-Bench this drove ~45% of all
OCR escalations: clean born-digital pages dominated by a figure, and scanned
pages that already carry a usable OCR text layer -- re-OCR adds nothing for
either, but each one was routed to the paid tier-3 OCR.
Route on the text signals only (near-empty or junk-quality layer). Image
coverage is still computed and still raises the `image_heavy` diagnostic flag,
but no longer routes. True scans with no/garbage text continue to escalate via
the empty-text and quality signals, so genuine OCR needs are unaffected.
Trade-off: image-only content on an otherwise-clean page (handwriting, stamps,
text inside figures) is no longer force-routed to OCR. This was previously
intentional; the escalation cost outweighed the benefit for RAG indexing.

Add test_check_status_completion_wakes_user_manager: register the auth tools
against a stub MCP, drive nc_auth_check_status through a completed Login Flow
(mocked storage + poll), and assert it stores the app password and rings the
background-sync doorbell. The MCP-tool wake path was previously only verified
by inspection (round-2 review nit); all three notify_user_provisioned() call
sites now have dedicated coverage.

Quality-gate fixes (new-code conditions on PR #902):
- new_security_hotspots_reviewed: drop the fake "http://nextcloud" host in the
manager tests to https:// (python:S5332 ×2).
- new_security_rating: generate the integration test's fake app password with
secrets.token_urlsafe instead of a hardcoded literal (python:S2068).
- new_reliability_rating: restructure the user_manager sleep so an explicit
await checkpoint lives inside the cancellation scope — await one waiter
directly while watching shutdown via start_soon (python:S7490). Behaviour is
unchanged: timeout, shutdown, or a provisioning ring all end the sleep.
Review nits:
- Move the shutdown test's fail_after(2) to wrap the whole task group so it
actually bounds the task-group exit (was guarding a no-op sleep); drop the
sleep(0) stub (python:S7491).
- Type _wake_on's wait_fn as Callable[[], Awaitable[object]].
- Note in _wire_vector_sync_state why provision_signal is set on the singleton
only, not fanned out to app.state.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- ProvisionSignal.wait() re-arms in a finally so a cancelled wait (shutdown
racing the doorbell) leaves a fresh unset event, not a stale set-but-consumed
one; preserves the no-await-before-swap lost-wakeup guarantee.
- Hoist user_manager_task's _wake_on helper out of the while loop (one object,
not one per iteration).
- Test: assert ProvisionSignal via its public wait() contract instead of the
private _event attribute.
- Add test_provision_app_password_wakes_user_manager covering the
api/passwords.py wake path (previously only LFv2 web + MCP tool were tested).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Background vector sync discovered newly provisioned users only on the
periodic user-manager poll (VECTOR_SYNC_USER_POLL_INTERVAL, default 60s),
delaying first indexing by up to a minute. Add a ProvisionSignal doorbell
that provisioning paths ring after storing a user's app password, waking
user_manager_task to re-poll and spawn the user's scanner at once. The
periodic poll remains the backstop (covers cross-replica provisioning).
- ProvisionSignal (stable reference, wait-and-re-arm) held on
VectorSyncState; closes the lost-wakeup window (no await between observing
the ring and re-arming; anyio.Event stickiness covers a mid-poll ring)
- user_manager_task races its poll timeout against the doorbell + shutdown
- notify_user_provisioned() rung from the three app-password provisioning
sites: Login Flow v2 web, MCP provisioning tool, management/BasicAuth API
Note: the pre-existing scanner_wake_event was never .set() and only wakes
existing scanners; a brand-new user has none, so the manager is what must
be nudged.

Address round-1 claude-review nits on PR #894:
- Document why offline_access is advertised unconditionally (independent of
settings.enable_offline_access): per RFC 8414, scopes_supported lists what
the AS *can* support, with actual issuance still gated upstream by Nextcloud.
- Add a regression test proving the offline_access invariant holds on an empty
FastMCP instance with no registered tools.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
discover_all_scopes() builds the scopes_supported lists exposed at
/.well-known/oauth-protected-resource and /.well-known/oauth-authorization-server.
It previously emitted only the base OIDC scopes plus tool-derived
@require_scopes, so offline_access was never advertised and
discovery-driven MCP clients had no way to know they could request a
refresh token.
Add offline_access unconditionally. The AS proxy already forwards
client-requested scopes upstream to Nextcloud, which issues a refresh
token when the MCP server's OIDC client is permitted the scope. This
only changes what is advertised; it is not added to ALL_SUPPORTED_SCOPES
(the app-level permission set), since offline_access is an OIDC behavior
rather than a Nextcloud resource permission.
Add a regression test asserting offline_access is always present in
discover_all_scopes() output.

Round-4 review on PR #893 (no blockers, minor items):
- Document why Mistral's _is_transient is SDK-level only (429/5xx): a bare
connection drop the SDK surfaces as httpx/ConnectionError isn't an SDKError
and isn't retried here by design — the pod-rollover target is the gateway
(OpenAI-compatible) path, which does cover connection errors.
- Include the last error (%r) in the retry helper's "not resolved after N
attempts" error log.
- Add test_mistral_embed_batch_retries_on_5xx (batch path parity with embed()).

Round-3 review on PR #891 (no blockers):
- Add test_encode_dav_path_encodes_exactly_once pinning the documented
decoded-input precondition ("already%20encoded.pdf" -> "already%2520...").
- format_exception_group: proper singular/plural ("1 sub-exception" vs
"N sub-exceptions") instead of "(s)".
- oauth_sync: use `if doc_task is not None:` to match processor_task's guard.

Round-3 review on PR #892 found a real bug: the gateway backend's httpx.Timeout
raises httpx.ReadTimeout (a httpx.TimeoutException, NOT a builtin TimeoutError),
so the `except TimeoutError` added in r2 only covered the Mistral
(anyio.fail_after) path — gateway timeouts still fell through to
reason="error". Catch both (TimeoutError, httpx.TimeoutException) so either
backend's timeout lands in the dedicated parse_failed_reason="timeout" bucket.
Add an end-to-end test driving a gateway httpx.ReadTimeout through the
processor.

Round-3 review on PR #893:
- record_qdrant_operation("upsert","error") now fires only when the exhausted
retry was actually a Qdrant failure (reason=="qdrant"); an embed/connection
failure exhausts retries before Qdrant is called, so attributing it to
mcp_qdrant_operations_total{error} inflated that signal. The cause is still
captured by record_ingest_dropped.
- Add test_mistral_embed_retries_on_5xx: exercises the full Mistral retry path
(5xx SDKError then success), not just the predicate.
- Add test_generate_does_not_retry_on_bad_request: generate() fast-fails on a
permanent 4xx.
- Move astrolabe_vector_ingest_dropped_total's definition into the astrolabe_
pipeline-metrics block (was in the mcp_ section).

Round-2 review on PR #891 (non-blocking):
- Add a parametrised test_webdav_path_encoding covering empty path,
leading-slash stripping, '#'/comma/space, and a non-ASCII name — the single
source of truth for every caller-path builder's encoding, so write_file /
delete_resource / create_directory / attachments are covered transitively.
- Document the decoded-input precondition on _webdav_path (encode-exactly-once;
passing an already-encoded path would double-encode).

Round-2 review on PR #892:
- OcrProcessor.process now catches TimeoutError separately and returns
parse_failed_reason="timeout" with a populated message ("OCR timed out after
Ns"), instead of conflating timeouts with API errors under "error" and logging
an empty suffix. Lets dashboards tell a too-low timeout from a failing
provider. Test added.
- Add validator-rejection tests for DOCUMENT_OCR_TIMEOUT_SECONDS=0 (gte=1) and
DOCUMENT_MAX_PDF_SIZE_MB=-1 (gte=0), matching the existing validator-test
pattern.
- Comment the _Settings test fixture's max_pdf_size_mb=0.0 default.

Round-2 review on PR #893:
- Add test_generate_retries_on_connection_error (generate() shares the transient
retry; guards the decorator against accidental removal).
- Add test_process_document_records_drop_on_exhausted_retries: drives
process_document to retry-exhaustion and asserts record_ingest_dropped is
called once with the classified reason (processor-level coverage, not just the
_drop_reason unit).
- Note in _drop_reason that a multi-failure group is labelled by its first leaf
(best-effort, no "mixed" bucket).

Round-1 review on PR #893:
- _drop_reason now descends through nested ExceptionGroups to the first leaf
(was single-level), so a doubly-wrapped cause isn't mislabelled "other";
added a nested-group test. Commented why both the httpx and openai isinstance
branches exist (raw Nextcloud-API errors vs SDK-wrapped variants).
- Documented that generate() intentionally shares the broadened transient retry
(RAG sampling path), with the worst-case latency note.
- Added a docstring note to process_document on how the provider-level retry
(5x) layers over the outer loop (3x in-process / 1x procrastinate).
- Added test_embed_batch_retries_on_connection_error for the batch path.
- Renamed test_retry_reraises_non_rate_limit_immediately ->
test_retry_reraises_when_predicate_returns_false (it tests the predicate, not
a specific status).
SonarCloud:
- S5708 (BLOCKER) on the helper's dynamic `except exception_type`: the type is
constrained to BaseException/tuple by the signature; suppressed with a
justified NOSONAR.
- S7503 (async without await) in the embed-retry test: use AsyncMock side_effect
instead of a hand-rolled async function.

- tests: use https in the OTLP endpoint fixture to clear the S5332
"http protocol is insecure" security hotspot (quality gate:

- cli: add the "tracing disabled" else branch in

OTLP endpoint is set.
- cli: trim the verbose inline comment in worker() (the WHY lives in the
helper docstring), per review.

Round-1 review on PR #892:
- Wire DOCUMENT_OCR_TIMEOUT_SECONDS into _MistralOcrBackend too (was
gateway-only): wrap process_async in anyio.fail_after so the SDK-managed
client honours the setting; on expiry it fails fast as a clean parse error.
Test added.
- Tighten the misleading "honoured without a restart" comment — per-call
get_settings() is for test monkeypatching; a live change still needs a
restart since the backend is cached for the pod lifetime.
- Comment the size guard's two intentional gaps: an explicit processor_name
override bypasses it, and the early return skips the parse-duration histogram.
SonarCloud (new-code smells in the added tests):
- S1244 float-equality asserts → pytest.approx (test_config.py, test_ocr_processor.py).
- S1186/S7503: rewrite the gateway-timeout test with mocker AsyncMock/MagicMock
instead of a hand-rolled fake client (no empty method, no async-without-await).

Round-1 review on PR #891:
- Guard processor_task's broad except handler against an unbound doc_task
(mirrors multi_user_processor_task): initialise doc_task=None before the loop
and branch the error log. Fixes a latent NameError if receive() raises a
non-TimeoutError/EndOfStream before the first document binds. Regression test
added.
- Drop the unnecessary `from __future__ import annotations` in vector/_errors.py
and express format_exception_group's non-group fast path as an explicit
isinstance check.
- Add a copy_resource Destination-header encoding test (analogue to MOVE);
strengthen the ExceptionGroup test to assert the full leaf repr survives.

The external split-worker ingest pods (MCP_ROLE=worker / procrastinate) had
no observability: the worker CLI entrypoint never started a Prometheus
metrics server and never configured structured logging, so the pods that do
the real parse/embed/upsert work were invisible to Prometheus and emitted
plain-text logs the platform pipeline couldn't parse.
The always-on API pod bootstraps observability in its lifespan (app.py), but
the worker has its own entrypoint and never went through that path (or
uvicorn's JSON log_config). Add `_init_worker_observability()` mirroring the
API pod: setup_logging (JSON), setup_metrics on METRICS_PORT when
METRICS_ENABLED, and setup_tracing when an OTLP endpoint is configured.
Runs after the INGEST_QUEUE=postgres check so a misconfigured worker fails
fast without binding a metrics port.
This also unblocks the document-pipeline observability shipped in #831
(Deck #175): the astrolabe_* parse/embed/chunk metrics and the
document_processor.parse span are recorded in the shared registry/processor
code the worker executes — they were simply never exposed in external mode
because the worker served no /metrics and set up no tracer.
Deck #310, unblocks #175.

From card 309 (OHR-Bench smoke-test triage): during a backend-pod rollover the
embedding endpoint was briefly unreachable, and openai.APIConnectionError /
ConnectError propagated unretried (the provider only retried 429). Documents
exhausted the 3 in-process retries and were dropped for that scan cycle.
Broaden the provider-level retry to the transient set -- APIConnectionError,
APITimeoutError, 429, and 5xx -- on the existing exponential backoff (2s->60s,
5 attempts), so a few seconds of retry rides through the rollover. Permanent
4xx (auth, bad request) still re-raise immediately. Generalize the shared
_retry helper (retry_on_rate_limit -> retry_on_transient, predicate renamed to
should_retry, accurate log label) with a back-compat alias; Mistral gets 429+5xx
for parity. The production gateway path inherits this via GatewayProvider, which
delegates to the decorated OpenAIProvider methods.
Add astrolabe_vector_ingest_dropped_total{reason}, incremented when a document
exhausts retries, classified (connection|timeout|rate_limit|server|qdrant|other)
by _drop_reason so the embed-drop rate is alertable per cause. Dropped docs are
NOT marked failed, so the next full scan re-picks them (re-queue via scan loop).

metric for AC #5).

Two ingest-robustness fixes from card 309 (OHR-Bench smoke-test triage).
The OCR backend timeout was a hardcoded 180s module constant, so a tenant
whose gateway has its own shorter ceiling couldn't tune it. Promote it to
DOCUMENT_OCR_TIMEOUT_SECONDS (default 180), resolved per call via get_settings
so an override applies without a restart.
Large, awkward PDFs (e.g. a 42 MB scanned DUDE) were handed straight to the
fast/OCR tiers, where they burned the full OCR timeout for zero recovered
text. Add a pre-parse size guard in the tiered PDF pipeline: a PDF over
DOCUMENT_MAX_PDF_SIZE_MB (default 50, 0 disables) fails fast with
parse_failed_reason="oversize" before any tier runs, so the existing
permanent-failure path marks the placeholder failed and records
astrolabe_document_parse_failed_total{reason="oversize"} instead of retrying.
Both knobs go through Settings + dynaconf validators (env-var keys verified by
regression tests) and are documented under Background Indexing Configuration.

Two ingest-robustness fixes from card 309 (OHR-Bench smoke-test triage).
WebDAV paths flowed through the client already URL-decoded (unquote on the
PROPFIND/REPORT <d:href>, or raw MCP-tool input), so a '#' reached httpx as a
URL fragment and silently truncated the request -> spurious 404 on otherwise
valid files (e.g. law filenames with '#', commas, double/trailing spaces).
Route every caller-path builder through a new _webdav_path helper that
percent-encodes the path once (preserving separators); the MOVE/COPY
Destination header is encoded too.
Vector-sync runs inside anyio task groups, so a child-task failure surfaced as
a BaseExceptionGroup whose str() is the useless "unhandled errors in a
TaskGroup (N sub-exception)" -- hiding the real ConnectError operators need.
Add format_exception_group to flatten the group to its leaf exceptions and use
it at the broad catch/log sites in processor.py and oauth_sync.py.

Round-6 review: the docstrings listed preserved fields but omitted
assignedUsers. Verified empirically (Deck 1.15.9) that the update route's
board-change handling only remaps labels and leaves user assignments
untouched, so assignees carry over. Documented in both the client and MCP
tool docstrings, with the caveat that an assignee lacking access to the
target board stays assigned but cannot act on the card. Added
test_move_card_to_board_preserves_assigned_users to lock it in.

The move-card unit tests added a mock httpx.Request with an http:// URL,
which SonarCloud flags as a new security hotspot (insecure protocol),
failing the new-code quality gate. The URL is never dialed (it only labels
a synthetic HTTPStatusError), but switch it to https to keep the gate green.
Also simplify the done-PUT mock to a bare 200 response, since that response
is discarded by the implementation.
