Chris CoutinhoandClaude Opus 4.8 15042c1b1b polish(mail): consistency guards (PR #935 round-7)
Non-blocking consistency fixes:
- scanner.py: skip re-queuing a mail_message whose placeholder status is
  "failed" (mirrors the file scanner's permanent-failure guard); the
  modified_at branch still retries once the message changes.
- search/context.py: return None on an empty get_message payload during context
  expansion, mirroring the processor's index-time empty-payload guard.
- tests: cover the non-numeric mailbox_id fail-open branch in the verifier.

Chris CoutinhoandClaude Opus 4.8 10e768e414 fix(mail): guard empty message payload in processor (PR #935 round-6)
- processor.py: raise on an empty mail_message payload (OCS data=null with a
  <400 meta) so the task dead-letters instead of indexing a near-empty
  placeholder — mirrors the nc_mail_get_message tool guard. (the round-6
  approve-gating item)
- server/mail.py: clamp limit once in nc_mail_list_messages and base has_more on
  the effective (post-clamp) limit, so a caller passing limit<=0 doesn't get a
  misleading count.
- server/mail.py: note in nc_mail_get_message that attachments with id=null are
  inline body parts and can't be fetched via nc_mail_get_attachment.
- tests: add the first-time-missing incremental scanner case (enters the grace
  period, nothing queued/deleted).

Chris CoutinhoandClaude Opus 4.8 d006145444 harden(mail): address PR #935 round-5 review
No blockers raised; residual cleanup:
- processor.py: guard int(doc_task.doc_id) with is_valid_nextcloud_doc_id in
  the mail_message branch (consistent with search/context.py + the verifier).
- mail metadata symmetry: store `bcc` in file_metadata and the Qdrant payload
  alongside cc (build_mail_content already emits a Bcc: line).
- server/mail.py: extract _cap_attachment_content helper (byte-accurate cap)
  and unit-test it (small/None/oversized/multibyte).
- client/mail.py: give the synthetic OCS-error Response an explicit empty body;
  add a test that a traversal-style attachment_id is percent-encoded.
- models/mail.py: clarify ListMessagesResponse.total_count is the page count,
  not the mailbox total.

Deferred (Deck #376): _potentially_deleted doc_type-in-key. It's pre-existing
and spans ~30 sites across the notes/news/deck/file/mail scanners (whose
deletion paths have no unit coverage), so it belongs in its own focused PR
rather than expanding this mail PR's blast radius into other doc types.

Chris CoutinhoandClaude Opus 4.8 891d07db12 perf(mail): batch verify-on-read; test build_mail_content; addr-recall
Address PR #935 round-3 review:

- search/verification.py: rewrite _verify_mail_messages to batch by mailbox.
  get_message triggers a server-side IMAP body fetch, so per-result verify
  issued one IMAP FETCH per hit; now it calls the DB-cached list_messages once
  per mailbox (mailbox_id comes from the Qdrant payload via result.metadata)
  and intersects — O(unique mailboxes) light calls instead of O(results) IMAP.
- vector/mail_content.py: include Cc/Bcc in the indexed text so recipient
  queries match; move MAIL_SCAN_MAX_PER_MAILBOX here (shared by scanner index
  window + verifier presence window) with a note that it equals the Mail OCS
  per-request max (100), so it's a fixed constant not a config knob.
- client/mail.py: clamp list_messages limit to 1..100 at the client layer.
- tests: add test_mail_content.py (exact-layout contract for build_mail_content);
  rewrite the mail verifier tests for the batch-per-mailbox shape.

Left as-is: ValidationError isn't caught in the list-endpoint tools — consistent
with nc_notes_*/nc_deck_* and not a regression.

Chris CoutinhoandClaude Opus 4.8 c62ccf3d0d fix(mail): address PR #935 round-2 review
- server/mail.py: guard nc_mail_get_message against an empty OCS payload so
  MailMessage(**{}) can't raise an uncaught ValidationError (returns a clean
  'not found' instead).
- server/mail.py: cap inlined attachment content at MAX_ATTACHMENT_CONTENT_BYTES
  (5 MiB), replacing oversized bodies with a sentinel so a large attachment
  can't blow up the MCP response.
- client/mail.py: harden the OCS meta statuscode parse against a non-numeric
  value (treat as success) instead of letting int() raise an uncaught
  ValueError.
- scanner.py: log the newest-N cap hit once per (user, mailbox) at info level
  (discoverable without flooding multi-tenant logs on every scan tick).
- tests: add incremental-sync scanner cases (new message queued, reappeared
  message clears grace, deletion after grace expiry).

Deferred (tracked, card #376): include doc_type in the _potentially_deleted
grace-period key — a pre-existing cross-cutting collision the reviewer flagged
as a follow-up, not a blocker.

Chris CoutinhoandClaude Opus 4.8 62ee3e9f32 refactor(mail): address PR #935 round-1 review
- models/mail.py: lowercase `list` generics per CLAUDE.md convention.
- client/mail.py: _ocs_get now inspects ocs.meta.statuscode (re-raises >=400
  as HTTPStatusError carrying the OCS code so callers' 404/403 handling
  applies) and guards response.json() against non-JSON bodies (RequestError).
- Extract the duplicated _format_addresses + content reconstruction into
  vector/mail_content.py, used by both processor.py and context.py (fixes the
  SonarCloud new_duplicated_lines_density gate).
- processor.py: add the missing mail_message Qdrant payload block so the
  computed mail metadata (subject/from/to/cc/date_int/has_attachments/
  account_id/mailbox_id) is actually stored, not dropped.
- Rename the list_messages `filter` param to `search_filter` (avoid shadowing
  builtins.filter); still maps to the OCS `filter` query param.
- Docstring notes: has_more heuristic, attachment content size.
- Tests: OCS meta-failure + non-JSON client paths; initial-sync scanner tests
  (tests/unit/vector/test_scanner_mail.py).

Chris CoutinhoandClaude Opus 4.8 3074622455 feat(mail): read and index Nextcloud Mail via the Mail OCS API
Add read-only support for the Nextcloud Mail app, plus semantic indexing
of mail messages. The MCP server never speaks IMAP/POP3 itself: it calls
the Mail app's CSRF-free OCS API (/ocs/v2.php/apps/mail/api/...) with the
existing Basic-Auth app-password flow and an OCS-APIRequest header, and the
Mail app handles IMAP server-side.

- client/mail.py: MailClient (accounts, mailboxes, messages, message,
  attachment), OCS-envelope aware.
- models/mail.py: Pydantic models with the API's camelCase aliases.
- server/mail.py: 5 read-only MCP tools (mail.read scope), registered in
  AVAILABLE_APPS.
- Vector pipeline: new "mail_message" doc_type wired into scanner
  (scan_mail_messages, newest-N per mailbox), processor (body -> markdown
  embedding), per-id verifier, and context expansion.
- Tests: client API, model round-trips, verifier behavior; consent-backstop
  test now derives its allowed set from INDEXED_DOC_TYPES.
- README + semantic-search docstrings updated.

Requires Mail 5.x / Nextcloud 32+ and a mail account configured in the
Mail app. Follow-up: astrolabe must advertise "mail_message" in its
enabled_doc_types capability for search under admin doc_type restriction.

Chris CoutinhoandClaude Opus 4.8 5b468514ec test(vector): use network-mode 404 signal + https in not-wrap test (#926)
- Clear SonarCloud hotspot python:S5332 (insecure http:// URL) by using
  https:// for the inert placeholder Qdrant URL in the network-mode test.
- Make the test faithful to production: stub the network existence-check
  with UnexpectedResponse(404) (what the real HTTP client raises) instead
  of the local-mode ValueError("not found"), per round-2 review.

Chris CoutinhoandClaude Opus 4.8 de960715c6 test(vector): address round-1 review nits on #926 offload proxy
- Use the reset_qdrant_singleton fixture in the network-mode test instead
  of manual save/restore boilerplate.
- Add a test locking down the sync-callable forwarding branch (callable
  returning a non-coroutine is passed through without thread offload).
- Document that _drive_local_coroutine treats a bare `yield None` as a
  non-suspension, and that the proxy is wrapped before the startup
  migrations so the O(N) backfill scroll also runs off the event loop.

Chris CoutinhoandClaude Opus 4.8 1701131017 fix(vector): offload embedded Qdrant ops to a worker thread (#926)
qdrant-client's embedded backends (:memory: and path= local mode) run
every operation synchronously on the calling thread despite the
AsyncQdrantClient surface — AsyncQdrantLocal contains no thread offload,
and this is unchanged through the latest v1.18.x (the async surface is
autogenerated from the synchronous QdrantLocal).

On a CPU-constrained host a background scan of thousands of tagged files
issues ~3 Qdrant queries per file, all on the event loop thread, pinning
one core at 100% and stalling /health/live, /health/ready, and the
outbound Nextcloud-reachability probe for minutes — the failure mode in
issue #926 (health-check timeouts, "nextcloud_reachable: error").

Wrap the embedded client in a transparent proxy that offloads every
coroutine-returning call to a worker thread via anyio.to_thread.run_sync,
keeping the event loop responsive. A dedicated CapacityLimiter(1)
serialises those offloads to preserve QdrantLocal's single-access
invariant (today guaranteed implicitly by the single-threaded loop).
Network mode (QDRANT_URL) is left untouched — it already does
non-blocking I/O. Centralised at get_qdrant_client() so all call sites
benefit.

Chris CoutinhoandClaude Opus 4.8 985fd5e8f2 test(ingest): use https test gateway URLs; doc fixes (review round 6)
Resolves the SonarCloud quality gate (new_security_hotspots_reviewed) — the 7
TO_REVIEW hotspots were all `http://gw` fake gateway URLs in test_ocr_processor.py
flagged "use https". Switched the test fixtures to `https://gw` (identical for a
fake URL) so no new hotspots remain to review; all other gate conditions already
passed.

Also address claude-review round 6:
- Stale test docstring: "suppresses to ocr" -> "suppresses to the cheapest
  registered OCR rung (here ocr-upstream)".
- OcrProcessor.__init__: comment that the upstream-shaped defaults are
  test/bare-construction convenience only; app wiring always passes args
  explicitly.

Left as-is (reviewer agreed): the `ocric=` signature abbreviation (opaque but
stable; renaming would invalidate dead-letter retries).

Chris CoutinhoandClaude Opus 4.8 d05cbc0dc1 docs(ingest): refresh BatchPending + classifier-vocab docs; add 4-rung suppressed test
Address claude-review round 5 on #922 (verdict: good to merge after the docstring):
- BatchPending docstring: the deferred job stays on its own `(ocr-upstream)` tier
  queue, not the retired `(ocr)` — batch mode is the upstream Mistral path only.
- classifier.py: clarify that `recommended_tier == "ocr"` is the classifier's
  COARSE vocabulary ("needs OCR"), resolved to a concrete rung
  (ocr-incluster -> ocr-upstream) by the registry — NOT a TIER_LADDER tier name.
- Added test_evaluate_escalation_suppressed_targets_incluster_four_rung: with both
  OCR rungs registered but both flags off, the suppressed what-if-OCR signal names
  the cheapest ideal rung (ocr-incluster), not ocr-upstream.

Chris CoutinhoandClaude Opus 4.8 0614709960 fix(ingest): warn when provider=none disables in-cluster; precise model fallback
Address claude-review round 4 on #922:

- Important 1: build_ocr_backend now warns when gateway_only + provider=none +
  DOCUMENT_OCR_INCLUSTER_ENABLED=true — provider=none suppresses the gateway-only
  in-cluster tier too (it never uses the mistral provider), which surprises an
  operator who set none just to disable Mistral. Restructured so the gateway_only
  branch is evaluated before the generic provider=none return. Two tests cover
  the warn-when-enabled / silent-when-disabled cases.
- Nit 3: model fallback uses `model if model is not None else ...` (not `or`), so
  an empty model string no longer silently falls back to the upstream default and
  misroutes a per-tier rung. Test added.
- Nit 4: the no-surya-literal guard now uses rglob so future
  document_processors/ subdirs are covered.

Deferred (pre-existing / out of scope for this PR):
- Important 2 (_GatewayOcrBackend opens a new httpx.AsyncClient per ocr() call):
  a pre-existing pattern affecting both OCR rungs; a shared pooled client needs
  careful per-pod lifecycle handling (event-loop binding, aclose) and is better
  as its own change. Follow-up.
- Nit 5 (_MANAGED_QUEUES vs the CLI all-queues list): the two sets differ
  deliberately (the CLI list includes ingest-maintenance, _MANAGED_QUEUES does
  not), so a shared constant wouldn't cleanly dedupe them.

Chris CoutinhoandClaude Opus 4.8 ebbf905dc5 fix(ingest): suppress misleading batch-fallback warn for in-cluster rung
Address claude-review round 3 on #922:

- Important: _process_batch emitted "no gateway backend (provider=mistral or
  EMBEDDING_GATEWAY_URL unset)" for the gateway_only in-cluster rung, where the
  gateway IS configured — sending operators chasing a non-existent config
  problem. The real reason is "in-cluster GPU is synchronous-only; batch is the
  upstream path". Guard the warning with `if not self._gateway_only`. Extended
  test_gateway_only_processor_never_uses_batch_mode to drive _process_batch and
  assert _batch_fallback_warned stays False.
- Nits: refresh stale ladder in escalation.py module docstring
  (fast->structured->ocr-incluster->ocr-upstream); fix "minimum='ocr'" ->
  "ocr-incluster" in a test docstring; rename stale tier="ocr" ->
  "ocr-upstream" in test_process_tier_oversize_fails_fast.

Chris CoutinhoandClaude Opus 4.8 6e32bd9561 refactor(ingest): doc legacy ocr queue; fix docstrings + getattr guard
Address claude-review round 2 on #922:

- Legacy `ingest-ocr` tier resolution (important 1): document why it deliberately
  resolves to `fast` rather than mapping to `ocr-upstream` — stranded pre-split
  jobs re-extract empty and re-escalate via the ladder to the cheap
  `ocr-incluster` rung, keeping them OFF the paid upstream rung. Added a
  tier_for_queue(LEGACY_INGEST_QUEUE_OCR) == "fast" assertion.
- Double get_settings() in `_get_batch_client` (important 2): bind once to a local.
- Stale docstrings (important 3): OcrProcessor (serves both rungs now),
  _tier_available (both OCR rungs gated), evaluate_escalation (targets
  ocr-incluster, falls through to ocr-upstream).
- Misconfigured model_setting (nit 5): OcrProcessor.__init__ raises ValueError on
  an unknown settings attr (fail-fast at startup vs AttributeError mid-OCR); also
  removes the dynamic-getattr static-analysis smell SonarCloud flagged.
- Redundant guard (nit 4): kept `and ocr_tier is not None` — it's required for ty
  to narrow ocr_tier to str for record_document_escalation; added a comment.
- Test gap (nit 6): added a test pinning the CURRENT incluster-failure ->
  tier-1 fallback (does NOT cascade to upstream) so the future 503-escalation
  change is an explicit diff.

Chris CoutinhoandClaude Opus 4.8 87b8edd139 test(ingest): cover ocr-incluster routing + fix scan-gate & batch guard
Address claude-review on #922:

Blocking — test coverage for the new tier2 rung:
- test_registry_tiering.py: inline empty-text routes to ocr-incluster before
  ocr-upstream; only-incluster-enabled routes to incluster; disabled-incluster
  skips to upstream; evaluate_escalation empty_text hops to ocr-incluster (and
  falls through to upstream when incluster off); next_available_tier walks the
  full fast→structured→ocr-incluster→ocr-upstream ladder + ignore_ocr_enabled
  ideal-target.
- test_escalation_signature.py: enabling document_ocr_incluster_enabled changes
  the dead-letter signature (independent of the upstream rung).
- test_tiered_escalation_strategy.py: structured→ocr-incluster hops to
  INGEST_QUEUE_OCR_INCLUSTER; tier_for_queue covers the in-cluster queue.

Important — real fixes:
- registry.py: run scan detection (image_coverage_per_page) when EITHER OCR rung
  is enabled, not just the upstream one — a tenant with only in-cluster OCR on
  was missing image-coverage scan signals.
- ocr.py: the gateway_only (in-cluster) processor never enters batch mode — the
  GPU is synchronous/low-latency; batch OCR is the upstream Mistral async path.
  _get_batch_client short-circuits to None. Covered by a new test.

Nit:
- cli.py: worker --tier help lists ocr-incluster/ocr-upstream as separate fleets.

Left as-is: the lazy anyio.Lock init in OcrProcessor — instances ARE created at
module import (document_processors/__init__.py), so deferring lock creation off
import time is still required; moving it into __init__ would reintroduce the
import-time-primitive issue the comment guards against.

Chris CoutinhoandClaude Opus 4.8 c21804fbbc feat(ingest): split OCR into tier2 in-cluster (GPU, gateway-only) + tier3 upstream
Insert a configurable in-cluster OCR rung into the escalation ladder (Deck #353):
a tier2-eligible doc is OCR'd on the on-demand burst GPU before falling through to
paid upstream OCR. The in-cluster backend is reached ONLY via the embedding gateway
(model prefix routes to the GPU over the tailnet) and is a config value (default
surya/surya-ocr-2, swappable to e.g. lightonocr) — never hard-coded.

Ladder: fast -> structured -> ocr-incluster -> ocr-upstream
(queues ingest-ocr-incluster / ingest-ocr-upstream).

- escalation.py: 4-tier ladder; in-cluster flag folded into the dead-letter signature.
- ocr.py: OcrProcessor(name, tier, model_setting, gateway_only); build_ocr_backend(
  ..., model=, gateway_only=) — gateway_only forces the gateway backend (never the
  direct Mistral fallback), disabling the tier with a warning if no gateway URL.
- registry.py: per-rung enable map; scanned docs target minimum="ocr-incluster";
  inline path runs the cheapest available OCR rung.
- procrastinate.py: two OCR queues; legacy ingest-ocr kept as a drain target.
- config.py: DOCUMENT_OCR_INCLUSTER_ENABLED (off) + DOCUMENT_OCR_INCLUSTER_MODEL.
- __init__.py: register the two OCR instances; vector/processor.py: pages_ocr
  metered for the upstream (paid) rung only; cli.py: new --tier choices + legacy drain.
- metrics.py: zero the legacy ingest-ocr queue gauge during rollout.
- tests: migrated to the split ladder + new tests (gateway-only forcing, per-tier
  model incl. lightonocr override, no-hard-coded-surya guard). 1792 pass; ruff + ty green.

- Add test_mcp_path_does_not_use_userinfo_for_opaque_token to pin that the
  userinfo fallback is management-path-only (MCP path still 401s).

Left as-is: the hasattr(settings, "userinfo_uri") guard — kept to mirror the
adjacent introspection_uri block (consistency requested in round 2). The
_verify_mcp_audience metric-when-unconfigured note is a pre-existing, out-of-

  _introspect_token → None) through to a successful userinfo validation,
  pinning the documented error fall-through end to end.

Chris CoutinhoandClaude Opus 4.8 ed32519563 fix(auth): document introspection-error fall-through, drop misleading userinfo metric
Address claude-review round 4 on #919:
- Functional concern: document that _introspect_token returns None for both an
  active=false response (the cross-client case we must handle) AND a network
  error, so both fall through to userinfo. This is safe — userinfo is itself an
  authoritative live check, so a flapping introspection endpoint can't cause an
  invalid token to be accepted.
- Observability nit: only record a ("userinfo", ...) metric when userinfo was
  actually attempted (userinfo_uri configured); a no-validators-configured
  opaque token now returns None without a misleading userinfo-failure metric.
  Added test_opaque_rejected_when_no_validators_configured.
- Added a comment on the post-validation cache re-read explaining why the entry
  is always present (write-then-read with no await between).

Chris CoutinhoandClaude Opus 4.8 bafe82c897 fix(auth): quiet cache-hit userinfo log, test real-exp userinfo path
Address claude-review round 3 on #919:
- Log spam: the userinfo allowlist-relaxation notice fired at WARNING on every
  request (incl. cache hits — frequent Astrolabe polling). Warn once on fresh
  validation; cache-hit re-validations now log at DEBUG.
- Test: add coverage for a userinfo response that DOES carry `exp` — the real
  token expiry must win over the short userinfo TTL.

Not changed:
- USERINFO_URI auto-discovery: already auto-populated from the OIDC discovery
  document in app.py (settings.userinfo_uri = discovery["userinfo_endpoint"],
  mirroring jwks_uri/introspection_uri), so OIDC_DISCOVERY_URL deployments need

Chris CoutinhoandClaude Opus 4.8 8acfe9655b fix(auth): harden userinfo fallback (anti-forgery, SSRF guard, unconfigured-introspection)
Address claude-review round 2 on #919:

- Anti-forgery: the `_auth_via_userinfo` allowlist-bypass flag is now sourced
  ONLY from an explicit in-process `via_userinfo` argument (derived from how
  the token was validated), never from the IdP payload. The payload claim is
  stripped from the cached entry, so a malicious introspection/userinfo
  response can't forge the bypass. Added a regression test.
- SSRF (CWE-918): guard the userinfo_uri scheme (http/https) before the request
  — documents the trusted-source assumption and fails fast on misconfig.
- Introspection-unconfigured: only attempt introspection (and record its
  metric) when an introspection endpoint is configured; otherwise go straight
  to userinfo. Avoids mislabelled introspect-invalid metrics. Added a test.
- Tests: cache-hit test now seeds via a real first call (behavior, not cache
  internals) and asserts the network is probed once; short-TTL test uses the
  explicit via_userinfo arg; moved hashlib usage out.

Addresses round-2 review on PR #920:
- Only dead-letter a terminal failure when the file has an etag to
  content-address the marker; without one, fall back to the legacy per-user
  placeholder mark (an etagless marker is unmatchable). + test.
- _dead_letter_filter now also matches is_placeholder=True (redundant with
  dead_letter=True but lets Qdrant use the is_placeholder payload index).
- TODO(deck-349) documenting the dead-lettered-then-deleted orphan-marker leak
  (out of scope; needs a marker sweep or TTL field) per reviewer.

Chris CoutinhoandClaude Opus 4.8 cd348b3233 fix(vector): clear dead-letter marker on delete, treat oversize as terminal
Addresses round-1 review on PR #920:
- Delete path now clears the file's dead-letter marker after
  release_document_for_user (whose principal-based filter misses the
  user-agnostic, principal-less marker), preventing orphan-marker accumulation
  for dead-lettered-then-deleted files.
- Oversize PDFs (rejected by the pre-parse size guard, no pipeline_tier stamped)
  are now treated as terminal regardless of failing_tier -- no tier can parse an
  oversize file -- so they dead-letter instead of falling to the legacy per-user
  mark on the inline path.
- Gate the success-path clear on a non-empty etag (an etag-less file can never
  have a marker, mirroring is_dead_lettered's early return).
- dead_letter.py: payload typed dict[str, Any] (CLAUDE.md).

Tests: oversize-terminal dead-letter and delete-path marker clear.

Chris CoutinhoandClaude Opus 4.8 8c9339501e fix(vector): dead-letter terminally-failed documents to stop multi-user re-queue loop
A pathological PDF (a 206-page ChronoScan scan with ~3400 JBIG2/JPX images)
jammed a tenant's structured ingest worker in an infinite reprocess loop,
re-burning a 120s pymupdf4llm parse (and occasionally OOM-racing the 2Gi pod)
every few minutes.

Root cause: the per-user placeholder "failed" mark could not stop the loop. The
placeholder point ID is user-agnostic (uuid5("file:<doc_id>:placeholder")) but
the scanner's freshness gate, query, and status update all filter by user_id.
For a file visible to several users the single shared placeholder's user_id is
overwritten by whoever scanned last, so every other user's scan sees "no record"
and re-queues -- an N-user ping-pong that never honours the failed status.

Fix: when a parse fails terminally (no higher escalation tier available, e.g.
structured with OCR off) record a durable, content-addressed, user-agnostic
dead-letter marker (mirrors vector/sharing_state.py). The scanner consults it
tenant-wide for every user and skips re-queuing until the content (etag) OR the
escalation-tier set (tiers_sig -- e.g. OCR enabled) changes, so the document is
attempted once per content-version instead of forever.

- new vector/dead_letter.py: mark/is/clear, content-addressed marker carrying
  is_placeholder=True (inherits search exclusion) + dead_letter=True
- escalation.escalation_tiers_signature(settings): retry-on-tier-change key
- processor: dead-letter terminal failures, clear on successful (re-)index
- scanner: user-agnostic is_dead_lettered skip beside claim_existing_index
- placeholder: exempt dead_letter markers from the orphan sweep (durability)
- metrics: astrolabe_document_dead_lettered_total{reason}

Deck #349.

Chris CoutinhoandClaude Opus 4.8 b128780aac fix(auth): tighten userinfo-token cache TTL and metric labelling
Address claude-review round 1 on #919:

- Security: userinfo responses carry no `exp`, so userinfo-validated opaque
  tokens were cached for the 1h default TTL — a revoked/expired token could be
  honored for up to an hour. Cache them for `userinfo_cache_ttl` (5 min)
  instead, and document the bounded-staleness window in the docstring.
- Metrics: when introspection AND userinfo both fail, record
  ("introspect","invalid") + ("userinfo","invalid") separately and set
  validation_method="userinfo" before the userinfo call so a userinfo
  exception caught by the outer handler is attributed correctly.
- Style: use the hasattr(...) + truthy pattern for userinfo_uri, matching the
  introspection block above it.
- Tests: cache-hit allowlist bypass for via-userinfo tokens; short-TTL
  assertion; userinfo timeout / connect-error / malformed-JSON fail-closed.

Chris CoutinhoandClaude Opus 4.8 0294a99cd4 fix(auth): validate opaque access tokens via userinfo fallback
The management API (used by the Astrolabe PHP app for /api/v1/apps and
/api/v1/webhooks) only accepted JWT access tokens. Opaque tokens were
sent to Nextcloud's oidc introspection endpoint, which returns
`active: false` for tokens minted for a *different* OIDC client (e.g.
Astrolabe) even when they are live — so every call 401'd. This surfaced
on the nx101294 tenant: webhook setup failed and the webhook-preset UI
(including the Files preset) showed empty, because getWebhookPresets
errors out before its `files`-always-available filter runs.

Add a userinfo-endpoint fallback in UnifiedTokenVerifier: when
introspection reports an opaque token inactive, validate it against the
discovered userinfo_endpoint (a 200 with a `sub` proves a live bearer
regardless of issuing client). userinfo returns no client_id/scope, so
such tokens are stamped `_auth_via_userinfo` and the ALLOWED_MGMT_CLIENT
allowlist is relaxed for that path only — authorization is still
enforced per-user (token sub == requested resource owner) by every
management endpoint. JWT and introspection paths are unchanged and still
enforce the allowlist.

Also bumps the astrolabe submodule to 0.29.0 (the deployed version that
exhibits the issue).

Chris CoutinhoandClaude Opus 4.8 11522f88b0 refactor(auth): drop built-in well-known MCP client list
The client registry derived display names from a hardcoded map of
"well-known" MCP clients (claude-desktop, claude-ai, continue-dev,
zed-editor, vscode-mcp). This baked a recognized-client list into the
server even though admission already requires explicit opt-in via
ALLOWED_MCP_CLIENTS (fail-closed when unset).

Mirror the management-API surface (ALLOWED_MGMT_CLIENT), which has no
built-in client list: remove the map and derive the display name
generically from the client_id. Default remains none; clients must be
added explicitly and DCR stays off unless ENABLE_DCR=true.

  used elsewhere (document_max_pdf_size_mb) and the config comment. Add a
  zero-disables test.
- Correct the document_escalation_suppressed_total comment: corrupt_glyphs CAN

  registered-but-disabled (evaluate_escalation follows minimum="structured" past
  the missing rung to a gated-off OCR). Add a test for that suppressed decision.

  glyph-corrupt escalates structured->ocr with reason corrupt_glyphs.

Chris CoutinhoandClaude Opus 4.8 33aadbcf80 fix(document-processors): inline/external parity when structured tier is absent
Address round-3 review on PR #914:
- When a glyph-corrupt doc's structured rung is NOT registered, the inline path
  now falls through to OCR (with reason corrupt_glyphs), mirroring the external
  next_available_tier instead of silently keeping the fast result. A structured
  parse FAILURE remains terminal (tracked via structured_failed), matching the
  external path which does not escalate a failure. Added a debug log for the
  unregistered case and "(OCR not attempted)" to the failure warning.
- Tests: inline + external glyph-corrupt fallthrough to OCR when structured is
  unregistered; glyph-corrupt + junk-quality both-flags precedence (structured
  wins over the bad_text_layer/ocr route).
- Note the total_chars>0 mutual-exclusion with the scanned branch in
  _route_from_signals.

Chris CoutinhoandClaude Opus 4.8 cf7209cd85 fix(document-processors): escalate glyph-corrupt PDFs to the structured tier
The fast (pypdfium2) extractor can leak raw glyph codes on subset fonts with a
broken /ToUnicode CMap. The result scores high on the existing text-quality
heuristic -- a uniform glyph/Caesar offset preserves whitespace and token
lengths -- yet is unsearchable. The structured (pymupdf) tier extracts the same
pages correctly.

Add a language-agnostic C0-control-character-ratio signal to the tier-0
classifier that detects this corruption and routes the document to a new
`structured` recommended_tier. Wire the fast->structured hop on the inline path
and generalise it so a low-quality-but-non-empty layer also tries structured
before OCR -- the inline and external ingest modes now follow the full
fast->structured->ocr ladder identically. A scanned / no-text-layer document
(total_chars == 0) still shortcuts straight to OCR, since a text extractor
cannot recover a pure raster.

New per-tenant tunable DOCUMENT_GLYPH_CORRUPTION_RATIO (default 0.02); escalation
metrics gain a `corrupt_glyphs` reason label.

Chris CoutinhoandClaude Opus 4.8 7a9e4a8681 fix(vector): propagate cancel in cleanup task; cover 403 + sweep-failure
Address round-1 review on #913 and the SonarCloud new_reliability_rating gate:

- credential_cleanup_task no longer catches the cancellation exception
  (Sonar python:S7497). A task-group cancel must propagate for structured-
  concurrency teardown; graceful shutdown still flows through shutdown_event,
  so the sleep no longer needs a cancel/break.
- Parametrize the scanner self-heal tests over 401 AND 403 (handled
  identically at both call sites) and add a test that a failing periodic
  sweep is logged non-fatally and does not crash the task.
- Log the stored-user count before the startup sweep (operability signal),
  add a debug line when the credential row was already gone, and document
  the at-most-one extra-401 convergence in _remove_stale_credential.

Chris CoutinhoandClaude Opus 4.8 3790cf6d60 fix(vector): self-heal stale app passwords on auth failure
Deleted/disabled Nextcloud users left their app_passwords row in storage,
so user_manager_task re-spawned their scanner every poll interval only to
401 again — an endless re-spawn/auth-failure loop (observed on
tenant-blackbox-demo: ~534 respawns/3h, matching the 60s poll interval).

- Delete the stored app password on a hard 401/403 in user_scanner_task
  (both the pre-validation and in-scan-loop paths), breaking the re-spawn
  loop at the source so the user-manager stops recreating the scanner.
- Add a periodic credential_cleanup_task backstop (hourly) that sweeps
  cleanup_invalid_app_passwords for anything the per-scanner path misses.
- Run the startup cleanup for all deployment modes: drop the stale
  `not oauth_enabled` guard so login_flow tenants (the cloud default) are
  covered. NOTE: login_flow startup now makes one concurrent OCS
  validation call per stored user before readiness.
