The Starlette lifespan started `vector_sync_metrics_task` with undefined
names `task_producer` and `receive_stream`. Those locals only exist inside
the `_wire_vector_sync_state` helper; in the lifespan the transport is bound
as `ingest_transport`. The undefined reference raised `NameError`, which
aborted the background-sync task group and crashed startup in every
deployment mode ("Application startup failed. Exiting.").
Introduced by fbe70ecd ("feat: backend-agnostic vector-sync gauges").
Pass `ingest_transport.producer` / `ingest_transport.receive_stream` at both
call sites (single-user app.py:1791, OAuth/login-flow app.py:2012).
Also fix 10 pre-existing `ty` possibly-missing-attribute diagnostics: the
deck indexing code in scanner.py, processor.py and search/context.py reads
full-DeckCard-only fields (description, type, owner, etag, lastModified) off
`stack.cards`, typed `list[DeckCard | DeckCardSummary]`. Freshly-fetched
stacks from `get_stacks()` always hold full DeckCards (the summary
projection only happens in the tool layer), so narrow with
`cast(list[DeckCard], ...)` — matching the existing pattern in
server/deck.py.

🟡 Performance: unified_search's _execute sorted but did not cap the merged
multi-doc_type pool, so N doc_types each fetched at search_limit sent
N*search_limit candidates into verify-on-read (one Nextcloud round-trip each).
Cap to search_limit*2 after the sort, matching vector_search, nc_semantic_search
and the viz_routes pattern — bounding verification cost to O(2*search_limit)
regardless of how many doc_types are requested.
🟡 Consistency: _get_deck_metadata_from_qdrant is the one internal Qdrant lookup
that uses a raw user_id filter instead of build_ownership_filter. This is not a
bug — deck cards are a documented cross-user gap (the Deck API is per-user, so
cross-user context can't be fetched with the caller's credentials) — but the
inconsistency was unexplained. Added a comment documenting the deliberate
self-only scope.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
1. Don't log unverified result titles: both search algorithms logged top-5
titles at DEBUG before verify-on-read; with owner-level share expansion the
unverified set can contain other users' docs. Algorithms now log a count
only; the verifying callers (server/semantic, viz_routes, api/visualization)
log verified titles after verify-on-read.
2. Cross-user FILE chunk context: get_chunk_with_context + the Qdrant chunk
helpers now take accessible_owners and use build_ownership_filter. For files
the expanded scope is honoured only after a per-file file_accessible_by_id
check (accessible_owners is owner-level, so the gate prevents a one-file
share recipient from reading any of the owner's cached chunks). note/deck/
news stay self-only (per-user APIs) — a documented gap. Both chunk endpoints
pass accessible_owners.
3. Algorithm usage: SemanticSearchAlgorithm is not dead (it backs the dense-only
option on the viz/API surfaces); added a clarifying comment in server/
semantic.py. Additionally wired accessible_owners + verify-on-read into the
/api/v1 search routes (unified_search, vector_search) so the astrolabe
surface is ACL-aware too — degrading gracefully to self-only/unverified for
non-provisioned callers instead of 401.
4. Overlapping conditions: build_ownership_filter no longer lists self in the
owner_id MatchAny branch (self is already covered by the user_id branch);
the owner_id branch carries only the OTHER owners.
Tests: build_ownership_filter dedup + chunk-bbox filter-shape updates; new
ACL-aware get_indexed_doc_types, cached-chunk lookup, and end-to-end cross-user
file chunk-context (recipient gets the chunk, non-recipient denied) tests.

Round-14 review surfaced one blocking and one important issue.
context.py: the comment justifying `skip_offset_lookup` claimed
chunk_start/end_offset weren't in _PAYLOAD_INDEX_FIELDS — round 13
indexed both as INTEGER, so the comment now actively misleads. Replace
with the real reason: an indexed chunk_index miss is canonical (both
paths hit the same Qdrant collection), and skipping the offset filter
avoids a redundant round-trip.
verification.py: hoist an is_valid_nextcloud_doc_id guard before the
`int(d)` cast in _verify_news_items, mirroring the boundary-validation
pattern already in _fetch_document_text. Coerce via `str(d)` because
SearchResult.id is `int | str` (D1 forward-compat widening). Malformed
ids now surface as a logger.warning rather than a generic debug line;
fail-open semantics are preserved.

- _group_int_doc_ids: use type(value) is not int instead of isinstance,
since bool is an int subclass and would otherwise stringify to
"True"/"False" and corrupt legacy payloads on backfill.
- Replace doc_id.isdigit() guards in 5 boundary sites
(api/visualization, auth/viz_routes, search/context note/news_item/
deck_card branches) with a shared is_valid_nextcloud_doc_id helper
that rejects "0", leading zeros, and Unicode digit classes
(superscripts, Arabic-Indic, Devanagari) which pass isdigit() but
cannot be valid MySQL AUTO_INCREMENT IDs.

- search/context.py: drop the doc_type=='file' guard on skip_offset_lookup
so notes / deck cards / news items also bypass the unindexed offset
fallback when chunk_index is available. Legacy chunk_index=None data
still uses the offset path.
- vector/qdrant_client.py: clarify the backfill/_ensure_payload_indexes
ordering invariant (backfill rewrites payload values only, never schema
or indexes). Acknowledge OSS-vs-Cloud uncertainty in the 400-branch
comment and the new-collection call-site comment.
- vector/scanner.py: hoist qdrant_client to function scope so the
file-scroll block doesn't depend on a name bound inside the
notes-scroll block.
- tests/unit/test_chunk_context_offset_gate.py: flip the note-with-
chunk_index test to assert the offset fallback is skipped.

Addresses the four 🟡 important findings from claude-bot review on PR #773:
str (non-Optional) and the guard would silently skip the Qdrant lookup
for an empty string. Removing the guard matches the type signature.
(`all([…, doc_id, …])` rejects None and empty string, plus
`assert doc_id is not None`). No code change needed.
`get_qdrant_client()` with a module-level `anyio.Lock`. Double-checked
locking keeps the steady-state hot path lock-free. Without this,
parallel cold-start callers could all enter the init block and run
`_backfill_doc_id_to_string` + `_ensure_payload_indexes` redundantly
(idempotent, but noisy). Pattern matches `auth/storage.py:2071`.
behavior with three tests covering the float-warning path (the gap
called out in the review), the str/None silent-skip paths, and the
int-grouping happy path.

🔴 Blocking finding from PR #773 latest review:
`get_chunk_bbox_and_page_from_qdrant` (`search/context.py:199`) still
declared `doc_id: int | str` and passed the raw value into
`MatchValue(value=doc_id)` at lines 239 and 256 without `str()`
coercion. After this branch's startup backfill normalises every Qdrant
`doc_id` payload to a string, an `int` filter would silently match zero
points — the function would return `(None, None)` instead of the
chunk bbox / page, and PDF highlight overlays would fail in production.
Take option 2 from the reviewer's two suggestions (annotation
tightening over inline coercion): the producer side of this PR has
already narrowed every other `doc_id` annotation to `str`, so this
function is the last hold-out. Pushing the contract into the type
system means `ty` will catch any future regression at the call site.
Production callers in `api/visualization.py` and `auth/viz_routes.py`
already pass `doc_id` (str) verbatim after the recent merge with
master's chunk_index-first refactor, so no caller-side changes needed.
Update the 9 calls in `tests/unit/test_chunk_bbox_helper.py` to use
string literals (`"42"` / `"99"` / `"1"`) instead of integers. The
mock doesn't validate `MatchValue` value types, so the tests passed
with stale int doc_ids today — but they were exercising a path
production no longer takes.

Resolves both 🟡 important issues from the latest review:
1. `page_number` was unconditionally overwritten in `viz_routes.py:696` even
when Qdrant's payload lacked the field, clobbering the value resolved
from `chunk_context.page_number`. The new helper returns each field
independently and both call sites only overwrite via `is not None`
guards, matching the existing logic in `visualization.py`.
2. The ~60-line `if chunk_index is not None: ... else: ...` Qdrant scroll
block was duplicated between `api/visualization.py` and
`auth/viz_routes.py`. Extracted into `get_chunk_bbox_and_page_from_qdrant`
in `search/context.py` alongside the existing private `_get_chunk_*_from_qdrant`
helpers; both routes now share ~12 lines of caller code.
New unit tests at `tests/unit/test_chunk_bbox_helper.py` cover the indexed
and offset paths, the `(bbox, None)` regression case, and graceful
degradation on Qdrant strict-mode 400 (which also closes nit #4).

- Remove unreachable doc_type=="file" branch (and pymupdf/pymupdf4llm
imports) from _fetch_document_text in search/context.py — the file
path is short-circuited in get_chunk_with_context before reaching it.
- Drop the redundant `username = request.user.display_name` alias in
auth/viz_routes.py; both Qdrant scroll filters now reference user_id
consistently with the rest of the handler.
- Add TestAdjacentChunkBoundary in tests/unit/test_chunk_context_offset_gate.py
covering chunk_index=0 (before-fetch gate closed) and
chunk_index=total_chunks-1 (after-fetch gate closed) — the two
off-by-one boundaries previously untested.

Qdrant scroll branch noting it is a legacy path for pre-astrolabe#75
clients and degrades gracefully on Qdrant Cloud strict mode.
Reviewer item #2 (extracting the duplicated scroll block into a shared
helper) deferred to a follow-up issue per the reviewer's "not blocking"
framing.

- 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.

Addresses the deferred half of PR #767 review issue 2: instead of just
documenting the "0/N misreport" with a logger.warning, propagate the
caller's None for chunk_index through the dataclass, position markers,
and response builders so callers can distinguish "unknown position"
from "actually chunk 0".
Changes:
- ChunkContext.chunk_index: int → int | None
- _insert_position_markers: chunk_index parameter is int | None; when
None, renders "Chunk ?/N" instead of "Chunk 1 of N"
- get_chunk_with_context: drops the effective_chunk_index local entirely.
Passes chunk_index (may be None) directly into both ChunkContext and
_insert_position_markers, in both the Qdrant fast path and the
doc-text fallback.
- Fast path: when chunk_index is None and chunk_text was retrieved via
the offset lookup (notes/cards), skip the adjacent-chunk fetch.
Index arithmetic from a default 0 would query the chunks at positions
-1 and 1 even when the actual chunk is, say, 5/20 — silently producing
wrong "before"/"after" text. Mark both sides as truncated instead.
- Drop the now-redundant logger.warning in the doc-text fallback (the
response correctly communicates the unknown state via chunk_index=None).
Both existing response builders (`api/visualization.py:657` and
`auth/viz_routes.py:717`) already serialise `chunk_context.chunk_index`
unconditionally; `None` becomes JSON `null`. No route changes needed.
Adds 5 regression tests:
- ChunkContext.chunk_index propagates as None in fast path
- ChunkContext.chunk_index propagates as None in doc-text fallback
- Fast path with chunk_index renders "Chunk N of M" correctly
- _insert_position_markers renders "?/N" for None chunk_index
- _insert_position_markers renders explicit index when supplied

Latest reviewer comment flagged five items on top of the original PR. This
commit addresses every one:
🟡 1. Skip the offset-based Qdrant fallback for `doc_type=file` when
`chunk_index` is supplied. Qdrant Cloud's strict mode rejects unindexed
filter fields with HTTP 400, which `_get_chunk_from_qdrant` catches and
logs at `logger.error` — masking real Qdrant problems in monitoring.
Notes/cards keep the offset fallback (cheap, useful for legacy data).
🟡 2. Add a `logger.warning` and clarifying inline comment in the doc-text
fallback path when `chunk_index` is None — surfaces the pre-existing
"0/N misreport" so callers can detect it. Type-nullability propagation
is deferred to a follow-up (out of scope for this hotfix).
🟢 3. Simplify `if chunk_text and doc_id_int is not None:` →
`if chunk_text:` with an inner `assert doc_id_int is not None` for
`ty` narrowing. The outer second clause was dead.
🟢 4. Add `doc_type` `FieldCondition` to the offset-based image lookup in
both `visualization.py` and `viz_routes.py` for parity with the
`chunk_index` branches.
🟢 5. Inline the `chunk_filter` local in `visualization.py` directly into
the `must=[]` list (matches `viz_routes.py` style).
Adds `tests/unit/test_chunk_context_offset_gate.py` with three regression
tests covering the gate matrix: (file, with-index → skip offset),
(note, with-index → still tries offset), (file, no-index → still tries
offset). Lives at top-level rather than `tests/unit/search/` to side-step
a pre-existing circular-init issue in `nextcloud_mcp_server.search`.

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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Add `doc_type` FieldCondition to the chunk_index-path highlighted-image
Qdrant filter in both `api/visualization.py` and `auth/viz_routes.py`,
matching the shape of `_get_chunk_by_index_from_qdrant`. Safe today (the
block is guarded by `doc_type == "file"` and Nextcloud file IDs are
globally unique) but prevents a latent bug if other doc types start
storing highlighted images.
- Demote `viz_routes.py` `ValueError` log from `error` to `warning` (lazy
%-style) — `_parse_int_param` raises on user-supplied bad input, which
is a 400 not a server error and shouldn't pollute error logs.
- Hoist `effective_chunk_index` to compute once at the top of
`get_chunk_with_context`, removing two duplicate assignments.
- Add `test_file_doc_type_qdrant_miss_yields_fast_404` to the management
endpoint tests, locking in the proxy-timeout fix contract.
- Add `tests/unit/test_viz_routes_chunk_context.py` mirroring management
coverage for the OAuth-session route: param forwarding (chunk_index /
total_chunks), `doc_type=file` fast 404, and 400 on invalid int params.

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.

Two related bugs surfaced in production while viewing chunks from the
Astrolabe frontend on the AWS-hosted MCP server:
1. PyMuPDF document closed: in _fetch_document_text the fallback path
referenced pdf_doc.page_count after pdf_doc.close(), raising
"document closed" and returning None. The slow PDF re-parse already
completed but its result was discarded. Capture page_count into a
local before close().
2. Slow/fragile chunk lookup: get_chunk_with_context filtered Qdrant by
(chunk_start_offset, chunk_end_offset). Those fields are not part of
the always-indexed payload schema, and with strict_mode enabled they
yield 400 errors. Even with manually-added indexes the filter is
fragile if a doc is re-chunked. Switch to chunk_index (always
indexed) as the primary lookup key, falling back to offset-based
lookup when callers don't supply it.
Plumb chunk_index/total_chunks through both the management API
(api/visualization.py) and the OAuth viz route (auth/viz_routes.py).
Apply the same change to the highlighted-image lookup so all four
chunk-context Qdrant queries prefer the indexed field.
Skip the slow PDF re-parse fallback entirely for files: when both the
chunk_index and offset Qdrant lookups miss, re-downloading and
re-parsing the source PDF won't find the chunk either, and routinely
exceeds 30s on large documents - which is the proxy timeout in
Astrolabe. Notes/cards keep the document-fetch fallback (cheap).
Removes dead code (_get_file_path_from_qdrant) that was only used by
the now-unreachable file fallback path.
Companion change in the Astrolabe app passes chunk_index from search
results through to the new endpoint params.

Implements optional context expansion for semantic search results that
fetches adjacent chunks (N-1 and N+1) from Qdrant to provide before/after
context. Removes configurable chunk overlap (default 200 chars) to avoid
duplicate text appearing in both context and excerpt.
Key changes:
- Add include_context and context_chars parameters to nc_semantic_search
and nc_semantic_search_answer tools
- Implement Qdrant cache fast path for chunk retrieval (avoids re-fetching
and re-parsing documents, especially important for PDFs)
- Add _get_chunk_by_index_from_qdrant() to fetch adjacent chunks
- Remove chunk overlap from before_context (last N chars) and after_context
(first N chars) to prevent duplicate text
- Fetch context in parallel with anyio.Semaphore (max 20 concurrent)
- Pass through page_number from SearchResult to SemanticSearchResult
- Remove document-level deduplication (keep chunk-level dedup from algorithm)
Context expansion is opt-in via include_context=true parameter. When enabled:
- Populates has_context_expansion, marked_text, before_context, after_context
- Adds truncation flags when context exceeds context_chars limit
- Falls back to document fetch for legacy data with truncated excerpts

nextcloud_mcp_server/server/semantic.py:161-255
This commit fixes two critical issues with PDF processing:
1. **Text extraction mismatch (context expansion bug)**:
- Indexing used pymupdf4llm.to_markdown() producing markdown text
- Context expansion used page.get_text() producing plain text
- Different text formats caused character offset misalignment
- Search would find correct chunk, but expansion showed wrong section
- Fixed by making context.py use pymupdf4llm.to_markdown() consistently
2. **Diagnostic logging for page number assignment**:
- Added logging to verify page_boundaries exist in metadata
- Added logging to verify assign_page_numbers() assigns values
- Helps diagnose why page numbers show as null in search results
3. **mime_type storage bug**:
- Fixed incorrect field reference in processor.py:405
- Was using file_metadata.get("content_type", "")
- Should use content_type from WebDAV response
Changes:
- nextcloud_mcp_server/search/context.py: Use pymupdf4llm.to_markdown()
for PDF text extraction to match indexing method
- nextcloud_mcp_server/vector/processor.py: Add diagnostic logging for
page boundaries and assignment, fix mime_type storage
- tests/unit/client/test_webdav.py: Fix import sorting

- scanner.py: Use file_info['id'] as doc_id instead of file_path
- scanner.py: Pass file_path in DocumentTask for content retrieval
- processor.py: Store file_path in Qdrant payload for later lookup
- context.py: Add _get_file_path_from_qdrant() to resolve file_id → file_path
- context.py: Update get_chunk_with_context() to handle file ID resolution
This makes the system resilient to file renames since file IDs are stable
identifiers in Nextcloud, while file paths can change.
Notes are indexed as "{title}\n\n{content}" in processor.py but were
being retrieved as just content during chunk expansion, causing
chunk_start_offset and chunk_end_offset to be misaligned.
This fix reconstructs the full content structure when fetching notes
for chunk expansion, ensuring the displayed chunks match the excerpts
shown in search results.
Fixes chunk/excerpt mismatch reported in vector visualization.

Major improvements to vector visualization page:
- Refactor PCA to display individual chunks instead of averaged documents
- Add context expansion module for fetching surrounding text from notes and PDFs
- Update deduplication to use (doc_id, doc_type, chunk_start, chunk_end) keys
- Fix Alpine.js rendering with chunk-specific keys including offsets
- Refactor authentication helper to return NextcloudClient for better reuse
- Add async context manager support to NextcloudClient
Technical details:
- viz_routes.py: Fetch specific chunk vectors instead of averaging per document
- context.py: New module supporting both notes and PDF text extraction via PyMuPDF
- search algorithms: Extract page_number, chunk_index, total_chunks from Qdrant
- vector-viz.js/html: Use chunk positions in expansion tracking keys
This enables users to see which specific chunks match their query
and view them with surrounding context in the PCA visualization.
