Chris CoutinhoandClaude Opus 4.7 3153c9dac4 refactor(search): pre-push review fixes for PR #750
Address findings surfaced by `pre-push-review` after the round 8 sweep:

- Add deck verifier symmetry tests (404, transient 5xx, unexpected
  exception, non-numeric metadata) so deck has the same shape as the
  notes/news/files verifiers. Also add unexpected-exception tests for
  the news and file verifiers, which had `except Exception` branches
  no test was reaching. Keeps the registry-style verifier coverage
  uniform.
- Modernize sibling field types in `VectorSyncState`, `AppContext`,
  and `OAuthAppContext` from `Optional[X]` to `X | None`, matching the
  `eviction_task_group: TaskGroup | None` field added in the round 8
  diff (resolves the inconsistency flagged by A6). The lone remaining
  `Optional` import is dropped.
- Reverse cross-reference direction in the verifier docstrings: the
  later-defined `_verify_deck_cards` and `_verify_news_items` now
  point at `_verify_notes` as the canonical hoisted-cast pattern,
  rather than `_verify_notes` forward-referring to verifiers defined
  below it.

Chris CoutinhoandClaude Opus 4.7 8a2626da6c refactor(search): address PR #750 round 8 review feedback
- Rename `verified_count` → `verified_chunk_count` to make the count
  granularity explicit at the field name (chunks vs unique docs).
- News verifier now fails open *per-item* on non-numeric stored doc_ids
  (matches notes/files/deck shape); a single bad id no longer rescues
  definitively-missing siblings from eviction.
- Update note-verifier integration test to use string doc_ids end-to-end
  to match production storage (scanner.py:241 stringifies note ids).
- Add regression test for the closed-task-group race guard in
  `verify_search_results` so the RuntimeError swallow is locked in.
- Convert remaining f-string logger calls in `server/semantic.py` to
  lazy %-style formatting (per repo convention).
- Document `evict_on_missing` as a developer/test flag (no env var) and
  flag the `get_file_info` 404→raise contract change in its docstring.
- Add a TODO(ADR-019) breadcrumb for the hardcoded 2× over-fetch so
  future tuning has a clear hook.

Chris CoutinhoandClaude Opus 4.7 3e981e647a refactor(search): address PR #750 round 7 review feedback
Round 7 raised 5 issues; this round addresses all of them and fixes
the underlying causes (not just the comments) where applicable so
they don't get re-flagged in future passes.

Critical:
- verified_count description in SemanticSearchResponse said "unique
  documents" but the value is len(verified_results), a chunk count.
  Description rewritten to accurately document chunk-level granularity
  AND explicitly call out the asymmetry with dropped_count (which
  counts unique (doc_id, doc_type) pairs).

- _verify_files false-eviction risk: the round-6 doc-only fix was
  re-flagged. Address at the source — widen WebDAVClient.get_file_info
  to raise HTTPStatusError on 404 (matching the rest of the client
  convention) and reserve None for the genuinely ambiguous
  malformed-PROPFIND case. _verify_files now keeps the result on None
  (cannot tell whether the file exists) and evicts only on a
  definitive HTTPStatusError 404. Tests updated; new test added for
  the malformed-XML keep-result path.

Non-critical:
- News verifier semaphore lifetime now explicitly documented: one
  slot held for one deduplicated fetch per search is the correct
  backpressure behaviour.

- Cross-reference comments in _verify_notes / _verify_deck_cards no
  longer claim "Mirrors X" pointing at functions defined later in
  the file; now use direction-neutral "parallel implementation in".

- accessible_by_type is mutated by concurrent run_verifier tasks; a
  comment explains why this is race-free under anyio's cooperative
  multitasking (distinct keys per task, no await between read and
  write) so a future reader doesn't add a redundant lock.

- Knock-on: tests/integration/test_rag.py wraps get_file_info in a
  try/except for the new contract.

Chris CoutinhoandClaude Opus 4.7 e8df6003c5 refactor(search): address PR #750 round 6 review feedback
Closes out the remaining nits flagged in the round-6 review.

Critical:
- _verify_files contract comment now enumerates all None-return cases
  (404 + malformed PROPFIND XML) and documents the false-eviction
  trade-off; self-healing via re-indexing recovers
- int(r.id) cast at the SemanticSearchResult boundary now raises a
  TypeError with explicit doc_type/value context instead of bubbling
  up as an opaque "Search failed: ..." McpError

Design observations:
- nc_semantic_search_answer docstring documents the per-note
  round-trip cost from the post-verification race guard
- News verification latency hint added to configuration.md
- SemanticSearchResponse exposes verified_count + dropped_count so
  short result pages on high-ghost-density indexes are
  distinguishable from genuine scarcity. verify_search_results now
  returns (kept, dropped_count); production caller and tests updated

Minor:
- Comment clarifies the .get() fallback in verify_search_results is
  defensive only (run_verifier always populates the entry)
- Eviction task-group guard narrowed from except Exception to
  except RuntimeError (the only documented failure mode of
  TaskGroup.start_soon on a closed group)
- Indexer logs a warning when a deck_card task is missing
  board_id/stack_id, surfacing data-quality issues at index time
  rather than at verification time
- New unit test covers the news verifier's non-numeric-id fail-open
  path (one bad doc_id keeps the entire batch)

Chris CoutinhoandClaude Opus 4.7 ffcca23a7b refactor(search): address PR #750 round 5 review feedback
Tightens verifier consistency, closes test gaps, hardens the fire-and-forget
eviction snapshot, and routes the new concurrency knob through Settings.

- Pre-flight ``int()`` guard in ``_verify_notes`` mirrors ``_verify_deck_cards``,
  so a non-numeric note id produces a type-specific log line instead of
  falling through to the generic "unexpected error" branch.
- Adds explicit 403 tests for the file and news verifiers (symmetry with the
  existing notes/deck 403 tests) plus a ``non_numeric_id_keeps`` test.
- ``AppContext`` and ``OAuthAppContext`` no longer snapshot
  ``_vector_sync_state.eviction_task_group`` at lifespan-yield time. Both
  expose it as a ``@property`` that reads the singleton dynamically, removing
  the order-sensitive race where a future startup-ordering change could
  silently degrade fire-and-forget eviction to inline forever.
- Adds ``verification_concurrency`` (env var ``VERIFICATION_CONCURRENCY``,
  default 20) to ``Settings`` with a dynaconf validator; ``verify_search_results``
  resolves the cap lazily from settings when the caller doesn't override it.
- Enriches the news verifier TODO to call out that ``batch_size=-1`` is
  intentional — a numeric ceiling would silently break correctness because
  any item beyond the cap would be missing from ``present_ids`` and dropped.
- Updates ``Optional[TaskGroup]`` to ``TaskGroup | None`` per project style.

Chris CoutinhoandClaude Opus 4.7 21e5608a39 refactor(search): address PR #750 round 2 review feedback
Implements fire-and-forget eviction (ADR-019 §"Lazy eviction"): the
search response no longer waits on Qdrant deletes, instead spawning
evict() on a long-lived lifespan-owned task group. Falls back to inline
eviction in modes without vector sync and in unit tests.

Also: harden _verify_news_items against non-numeric ids (fail open
instead of crashing the verifier); document the get_file_info None-on-404
contract; add INDEXED_DOC_TYPES single source of truth in vector/scanner.py
referenced by the CI-guard test; write a Verify-on-Read Latency Budget
section in docs/configuration.md covering the unbounded news.get_items
fetch. Closes the two remaining ADR-019 implementation checklist items.

Chris CoutinhoandClaude Opus 4.7 7784ec02d7 refactor(search): address PR #750 review feedback
- Cap all_results to limit*2 after sort in the per-doc_types branch of
  nc_semantic_search to bound over-verification (was unbounded N-types).
- Switch BatchVerifier from (client, doc_ids, user_id) to (client, results,
  semaphore). Verifiers now read file paths and deck board/stack ids from
  SearchResult.metadata instead of doing fresh Qdrant scrolls — eliminates
  one duplicate round-trip per file/deck-card verification.
- Bound per-id verification concurrency with a shared anyio.Semaphore
  (default 20, matching server/semantic.py context-expansion convention).
  Prevents httpx pool exhaustion / rate limiting on large search pages.
- Propagate stack_id from Qdrant payload to SearchResult.metadata in both
  bm25_hybrid.py and semantic.py (board_id was already propagated).
- Drop now-unused _resolve_file_path / _resolve_deck_metadata helpers.
- Drop redundant int(d) in requested predicate from _verify_news_items.
- Rewrite eviction comment to be honest about inline (not background)
  execution and the resulting latency coupling.
- ADR-019 status: Proposed -> Accepted.
- Add news property to NextcloudClientProtocol.
- Widen SearchResult.id and SemanticSearchResult.id to int | str to match
  BatchVerifier signature and document support for future string-id types.
- Flip openWorldHint to True on nc_semantic_search_answer (it calls into
  Nextcloud via nc_semantic_search).

Chris CoutinhoandClaude Opus 4.7 d90e793d19 feat(search): verify-on-read for semantic search results (ADR-019)
The vector index lags Nextcloud (5-min webhook cron + scanner interval),
producing ghost records for deleted/unshared documents until the next
reconciliation. Verify each unique document against Nextcloud at query
time, drop inaccessible results, and lazily evict the corresponding
Qdrant points.

Per-doc_type batch verifiers: notes/files/deck cards run concurrently
per id; news items use a single fetch + intersect to avoid the per-item
fetch-all amplification. Transient errors fail open (keep result, log
warning) — only definitive 4xx drops. Multiple chunks of the same doc
collapse to one verification call.

Wired into nc_semantic_search before the limit trim and before context
expansion. nc_semantic_search_answer's per-note re-fetch retained as a
sub-second race guard since verification now happens upstream.
