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.

Two unrelated CI failures on this branch, one fix each:
- tests/integration/test_deck_vector_search.py: pass str(card.id) to
get_chunk_with_context. The function's contract is doc_id: str
(keyword-indexed in Qdrant), and real callers (viz_routes.py URL
path, server/semantic.py via str(result.id)) all stringify. The
test was the only int caller, hitting the .isdigit() guard added
earlier on this branch.
- tests/server/login_flow/test_login_flow_integration.py:
test_check_status_provisioned now accepts scopes=None as valid.
Per ProvisionStatusResponse in models/auth.py, None is the
documented sentinel for "all scopes granted" — and the web
provisioning path (provision_routes.py, used by Astrolabe's
"Enable Semantic Search" flow exercised by the new regression test
added on this branch) stores exactly that. The previous
is-not-None assertion hid behind test order until that flow ran.
- Replace anyio.sleep(0) with anyio.lowlevel.checkpoint()

Skip and warn instead of stringifying floats / unexpected types in the
backfill helper. A stray doc_id=3.0 would otherwise be rewritten to
"3.0", which producers (str(int)) and the keyword index would never
match, and which int() on the verification side would reject. Also add
a doc_id=0 case to the backfill test to guard against a future
falsy-skip regression.

Add the missing end-to-end coverage for the seam that PR #773's
`ALLOWED_MGMT_CLIENT` ↔ `astrolabeMcpClientOAuth00000000000` drift
bug exposed: browser → Astrolabe (NC PHP app) → MCP server's
management API on the `mcp-login-flow` profile. Every existing
`tests/integration/test_astrolabe_*.py` is marked `multi_user_basic`
and exercises the BasicAuth flow, not Login Flow v2 / OAuth.
The new test mirrors the production-shaped flow exactly:
1. Log in as admin via Playwright.
2. Navigate to `/settings/user/astrolabe`.
3. Click the "Enable Semantic Search" OAuth link rendered by
`oauth-required.php`. (Same selector Astrolabe's own e2e helper
uses — `third_party/astrolabe/tests/e2e/helpers/authorize.ts`.)
4. Click "Allow" on the Nextcloud OIDC consent screen.
5. Wait for the redirect back to the Astrolabe settings page.
6. Assert the "Enable Semantic Search" link is no longer visible.
Step 6 is the canary for the drift class: if Astrolabe's management
API call to `/api/v1/users/{id}/session` is rejected (HTTP 401, the
original bug), the session lookup falls back to "no token" and the
same `oauth-required.php` template re-renders with the link still
present — so the test fails loudly with a message naming the
likely cause.
Reuses `login_to_nextcloud` and `navigate_to_astrolabe_settings`
helpers from `tests/integration/test_astrolabe_multi_user_background_sync.py`
(already pattern-imported by the Plotly viz test). No fixture-level
OIDC client creation: `app-hooks/before-starting/26-configure-astrolabe-oauth.sh`
already provisions `astrolabeMcpClientOAuth00000000000` with the
correct redirect URI and scopes when `MCP_SERVER_URL` is set in the
shell that runs `docker compose --profile login-flow up`.
The test skips cleanly when admin is already authorized (typical
state on a re-run against a long-lived dev stack), so it's safe to
run repeatedly without manual reset.

🔴 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.

The previous commit moved `mcp-login-flow`'s `ALLOWED_MGMT_CLIENT` to
`astrolabeMcpClientOAuth00000000000` so production-shaped Astrolabe
traffic actually validates. Update the management API test fixture to
match: the static OIDC client created in
`tests/server/login_flow/conftest.py:login_flow_static_client_credentials`
now uses the same id `app-hooks/before-starting/26-configure-astrolabe-oauth.sh`
provisions in real deployments, so the test path exercises the same
code as production rather than a substituted fixture-only id.
`mcp-multi-user-basic`'s allowlist is unchanged
(`nextcloudMcpServerUIPublicClient`) and the shared
`configure_astrolabe_for_mcp_server` fixture in `tests/conftest.py`
keeps that as its default, so multi-user-basic tests are unaffected.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
The `mcp-login-flow` profile's `ALLOWED_MGMT_CLIENT` was set to the
test-fixture id `nextcloudMcpServerUIPublicClient` only, but the actual
Astrolabe app provisions its OIDC client as
`astrolabeMcpClientOAuth00000000000` (see
`app-hooks/before-starting/26-configure-astrolabe-oauth.sh:39`). All
tokens issued through the "Enable Semantic Search" flow were rejected
with HTTP 401 by `unified_verifier.py:222-227`'s allowlist check, and
the Astrolabe UI's retry loop subsequently exhausted the
`api/passwords.py` 5/hr rate limit (HTTP 429).
Switch the `mcp-login-flow` allowlist to Astrolabe's client id so
production-shaped traffic actually validates. The `mcp-multi-user-basic`
profile keeps `nextcloudMcpServerUIPublicClient` for the
`configure_astrolabe_for_mcp_server` test fixture.
Also bump `third_party/astrolabe` 0.13.12 → 0.14.0 to pull in the
chunk-context indexed-lookup fix (#75) and the PDF bbox highlight
overlay (#76) that match the master-side changes already merged on
this branch.

Reviewer findings (1 blocking + 2 important):
- 🔴 Replace `import asyncio` / `await asyncio.sleep(0)` with
`import anyio` / `await anyio.sleep(0)` in the four async side-effect
helpers (_scroll_raises, _upsert_raises, _get_collection_raises,
_create_index). CLAUDE.md mandates anyio for all async operations;
conftest pins the backend to asyncio so the asyncio.sleep call worked
today, but the inconsistency would surface the moment that pin moves.
- 🟡 Replace the sentinel's zero dense vector with a single non-zero
element (`[1e-9] + [0.0] * (dimension - 1)`). Cosine distance is
mathematically undefined for the zero vector and Qdrant Cloud strict
mode rejects zero-vector upserts. The exact value doesn't matter
(sentinel never participates in a search — no user_id/doc_id/doc_type
payload) but the upsert itself must be valid.
- 🟡 Avoid the duplicate `get_collection` round-trip on every restart.
`_ensure_payload_indexes` now accepts an optional
`existing_schema: dict | None` parameter; when None it fetches
collection_info itself (and the get_collection-failure swallow still
applies), but `get_qdrant_client` already fetches collection_info
for dimension validation in the existing-collection branch — pass
`collection_info.payload_schema or {}` through to skip the second
call. The new-collection branch passes `existing_schema={}`
explicitly since a freshly created collection has no payload schema.
The 🟡 deck_card iteration-fallback finding doesn't apply: the
`isdigit()` guard at context.py:612 returns early before either the
fast-path or the iteration fallback runs, so non-numeric doc_ids
cannot reach the inner `c.id == int(doc_id)` comparison.

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).
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Reviewer feedback (2 items):
- Add a BOOL payload index for `is_placeholder` alongside the three
KEYWORD fields. Strict-mode index-required filtering on Qdrant Cloud
enforces a payload index on any field used in a `FieldCondition`
regardless of value type, so `get_placeholder_filter` and
`delete_placeholder_point` would have produced HTTP 400 on Cloud
instances even after this PR's KEYWORD fix.
Implementation: replace `_KEYWORD_PAYLOAD_FIELDS: tuple` with
`_PAYLOAD_INDEX_FIELDS: dict[str, PayloadSchemaType]` so each
field carries its own schema type. Rename
`_ensure_keyword_payload_indexes` to `_ensure_payload_indexes` since
the function now creates more than just KEYWORD indexes. The
per-field log line now includes the schema type
("Created KEYWORD payload index on 'doc_id'", "Created BOOL payload
index on 'is_placeholder'") so operators can tell which type was
created without checking the source.
- Correct the misleading `wait=True` docstring in
`_apply_backfill_writes`. The previous wording said
`_ensure_payload_indexes` runs "immediately after this function",
but `_apply_backfill_writes` is called in a loop inside
`_backfill_doc_id_to_string` — the index creation runs after the
backfill function *returns*, not after each write. Rewrote the
docstring to capture both load-bearing reasons:
(1) per-batch commit ordering for crash-recovery safety, and
(2) ensuring the keyword index built later covers committed
payloads only.
Adds `test_ensure_payload_indexes_includes_is_placeholder_as_bool`
asserting the schema type is BOOL specifically. Existing tests
updated to use the new dict-based registry (side_effect lists now
extend to all four entries; field-set assertions derive from the
registry instead of hardcoding 3 KEYWORD names).

`<d:href>` is required by RFC 3986 to be percent-encoded, so non-ASCII
filenames (e.g. Chinese, Cyrillic) were leaking through `list_directory`
and the SEARCH-based tools (`find_by_name`, `find_by_type`,
`list_favorites`, `search_files`) as their URL-encoded form. Decode with
the already-imported `urllib.parse.unquote` before exposing to callers.

Reviewer feedback (3 important + 3 nits):
- Wrap _ensure_keyword_payload_indexes' get_collection() call in
try/except. The qdrant_client singleton is already assigned by the
time this function runs, so a transient timeout/DNS failure
propagating out left the process holding a usable client with the
migration silently skipped on every subsequent call. Now logs ERROR
with exc_info and returns; next process restart retries.
- Add `and "doc_id" in point.payload` guard to the four set
comprehensions in scanner.py (indexed_doc_ids, indexed_file_ids,
indexed_item_ids, indexed_card_ids). Previously a payload missing
the doc_id key would raise KeyError and crash the entire scan.
- Tighten test_ensure_keyword_payload_indexes_logs_400_as_warning to
match the per-field warning prefix exactly (`startswith("Schema
conflict on payload index")`), so a future change adding 400s to
the partial-failure summary surfaces here as a count mismatch.
- Add new-collection vs existing-collection context to the
_backfill_doc_id_to_string docstring's `dimension` parameter.
- Replace the misleading "rewrote 0/N from int to str" wording when
no rewriting was needed with "N points scanned, none required
rewriting (collection already in str form)".
- Add test_ensure_keyword_payload_indexes_logs_and_returns_when_
get_collection_raises mirroring the scroll-failure test.
SonarCloud (1 CRITICAL + 1 MINOR):
- Refactor _backfill_doc_id_to_string to bring cognitive complexity
under 15 (was 19). Extracted two pure helpers: _group_int_doc_ids
(group point IDs by stringified doc_id) and _apply_backfill_writes
(apply set_payload calls and return rewritten count). The main
function's scroll/loop/sentinel structure is unchanged.
- Add `await asyncio.sleep(0)` to the three async test side_effect
helpers (_scroll_raises, _upsert_raises, _create_index) so they use
an actual async feature (S7503). The async-callable shape is still
required to avoid the AsyncMock unawaited-coroutine warning when
side_effect raises.

Addresses three important findings from the latest reviewer comment:
- Add progress INFO log every 20 scroll batches (≈5120 points at
batch_size=256) in _backfill_doc_id_to_string so a long-running
migration on a large collection (50k+ points) doesn't look like a
startup hang. The line carries collection name, scanned count, and
rewritten count so it doubles as a heartbeat.
- Track non-400 failures in _ensure_keyword_payload_indexes and emit
a WARNING summary line listing every field that failed to get an
index. Per-field ERROR lines are easy to miss in startup noise; the
summary makes the partial-failure state visible at a glance.
- Split the sentinel upsert out of the data-scroll try/except in
_backfill_doc_id_to_string. A scroll-time failure still logs ERROR
with the new "scroll failed" wording (data is incomplete). A
sentinel-write failure now logs WARNING with "data succeeded but
sentinel write failed" wording — data is correct, only the
short-circuit marker is missing, and the next restart re-scrolls
an already-clean collection (idempotent zero-write) before retrying
the upsert.
Also fix the RuntimeWarning emitted by
test_backfill_logs_and_returns_when_scroll_raises: replace the bare
`RuntimeError` side_effect with an async-callable side_effect so
AsyncMock awaits the coroutine before the exception propagates.
Three new unit tests cover the new branches:
test_backfill_emits_progress_log_every_20_batches,
test_backfill_logs_warning_when_sentinel_upsert_fails,
test_ensure_keyword_payload_indexes_summarises_failed_fields.

- 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.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- Remove three stale `# Use numeric file ID` / `# Pass file path` comments
in scanner.py. file_id is already normalized to str() above each call
site, so the inline comments mislead readers.
- Wrap `_backfill_doc_id_to_string` scroll loop + sentinel upsert in
try/except Exception. The qdrant_client singleton is assigned before
this migration runs, so a transient scroll failure was leaving the
process holding a usable client with int payloads permanently
unbackfilled until the next restart. Catch broadly, log ERROR with
exc_info, and return without writing the sentinel — next process
restart retries from scratch.
- Note `:memory:` mode behavior near the sentinel constants so future
readers don't read the every-start scroll as a bug.
- Document the two degraded-migration ERROR log signals in
docs/configuration.md so operators know when a clean restart is
required to recover indexing.
- Add unit test asserting scroll-time exceptions are logged and swallowed
without writing the sentinel.

- api/visualization.py, auth/viz_routes.py: add comment on the offset-only
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

- pdf_highlighter.compute_chunk_bboxes_batch: drop unused chunk_text
destructure (SonarQube finding), and replace positional
page_boundaries[page_num - 1] with a key-based next() match so
reordered or non-1-indexed boundaries can't silently shift the bbox.
Convert touched f-string log to lazy %s formatting.
- vector/processor: rename the trace_operation span from
"vector_sync.generate_highlights" to "vector_sync.compute_chunk_bboxes"
to match what the function actually does.
- Add test_compute_chunk_bboxes_handles_unordered_page_boundaries —

- 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.

- chunk_bboxes is now dict[int, list[tuple[...]]] holding the bbox list
directly, not {"bbox": ..., "page": ...}. The page from text-search was
stored but never read; page_number from offset-based assignment is
authoritative for the Qdrant payload.
- Add two unit tests for the documented omission contract: chunks whose
offsets fall outside every page boundary, and chunks whose text cannot
be located on the rendered page, are silently dropped from the result.

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

- _ensure_keyword_payload_indexes: distinguish 400 (schema conflict, warning)
from other status codes (5xx/network, error) so a transient outage doesn't
silently leave the collection unindexed.
- build_search_result_from_point: use .get("doc_id") + return None on missing
instead of KeyError-crashing the search; reverse metadata merge order so
payload-derived chunk_index/total_chunks win over caller-supplied extras.
- docs/configuration.md: restore the OpenAI/Mistral/Bedrock/Simple provider
sections + reference-table rows that were dropped in the rebase. Reword
the "Startup migrations" bullet to describe what the code actually does
(no sampling — full scroll, zero writes when clean). Add operator note
about the SemanticSearchResult.id TypeError path.
- tests: pytest.approx for float equality (Sonar python:S1244); coverage
for non-400 → ERROR, payload={doc_id: None}, and missing doc_id key.

- Drop chunk_bbox_page from Qdrant payload — viz endpoints never read it
(page_number is the canonical PDF page field).
- Bump upsert BATCH_SIZE 10 → 100 now that payloads no longer carry PNGs.
- compute_chunk_bboxes_batch: move doc.close() into finally, replace
unused stored_page_num with _.
- purge_page_images.py: switch to anyio.run() per project convention,
and wrap AsyncQdrantClient in try/finally so the aiohttp session is
always closed (the class doesn't implement async-context-manager).
- Decorate new bbox unit tests with @pytest.mark.unit so they run under

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`.

Per-chunk PDF page renders (~150–700 KB base64 PNG each) were the dominant
disk consumer in production, repeatedly tripping `No space left on device:
WAL buffer size exceeds available disk space` on welcomed-malamute Qdrant.
Replace the inline highlighted_page_image / highlighted_page_number /
highlight_count fields with a small `chunk_bbox` field:
list[(x0, y0, x1, y1)] of normalized [0, 1] floats, ~32 bytes per chunk.
Astrolabe (the only known consumer) renders the highlight client-side as
a percentage-positioned overlay on top of the existing /api/v1/pdf-preview
render-on-demand path (cbcoutinho/astrolabe#76).
- pdf_highlighter: new compute_chunk_bboxes_batch() that reuses the
existing _find_chunk_bbox text-search path, skipping all pixmap/PIL/PNG
work.
- processor: store chunk_bbox + chunk_bbox_page in the Qdrant payload,
drop highlighted_page_image + friends, drop the base64 import.
- visualization /api/v1/chunk-context and auth/viz_routes: read
chunk_bbox instead of highlighted_page_image.
- vector/__init__: stop eagerly re-exporting `processor`/`scanner` —
fixes a pre-existing circular import (search.algorithms ->
vector.placeholder -> vector/__init__ -> processor -> scanner ->
server.semantic -> search.bm25_hybrid -> search.algorithms partial).
Test suite that was broken on master (test_bm25_hybrid.py et al.) now
collects and passes.
- scripts/purge_page_images.py: ad-hoc, idempotent migration that
delete_payload's the legacy keys from existing points. No reindex
required; legacy chunks render the page with no overlay.
Pairs with cbcoutinho/astrolabe#76. Frontend handles missing chunk_bbox
gracefully, so this can land in either order.

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.

- 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.

- Replace bare int() casts for start/end/context_chars in chunk_context_endpoint
with _parse_int_param, matching visualization.py bounds (0–10M for offsets,
0–10K for context_chars), and add the missing end > start guard.
- Initialize page_number from chunk_context.page_number so non-file doc_types
surface it; include page_number, chunk_index, and total_chunks unconditionally
in the response. Only highlighted_page_image stays gated on its own truthiness.
- Add a chunk_index forwarding regression test that asserts the new kwargs reach
get_chunk_with_context and appear in the response payload.

PR #767 review noted that the OAuth viz route used bare int() parsing for
chunk_index and total_chunks while the bearer-token visualization route
validates them via _parse_int_param. Mirror the same bounds check so
total_chunks=0 and negative chunk_index return 400 instead of silently
suppressing adjacent-chunk context.

- test_registry.py: stub `mistralai.client.Mistral` in
`test_registry_mistral_wins_over_ollama`, mirroring the sibling
picker test, so the test doesn't depend on the SDK accepting
arbitrary keys.
- openai.py: convert remaining f-string `logger.info(...)` calls to
lazy `%s` formatting, aligning with the pattern in mistral.py and
the repo's logging convention.
- test_mistral.py: add four tests covering the defensive RuntimeError
guards in `embed()` and `_embed_batch_request()` — empty
response.data, single null embedding, batch null embedding, and
count-mismatch.
- docs/configuration.md: add `AWS_ACCESS_KEY_ID` and
`AWS_SECRET_ACCESS_KEY` rows to the env-var reference table; they
were already mentioned in prose but missing from the table.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
- _retry.py: replace `assert last_error is not None` with explicit
`if last_error is None: raise RuntimeError(...)` so the original
rate-limit error is preserved under `python -O`.
- openai.py: drop the `_retry_factory` alias chain; rename the bound
decorator to `_retry_429` to match the pattern in mistral.py.
- mistral.py: comment the imports so future reviewers understand why
`from mistralai.client import …` is the canonical path on 2.x (no
top-level `__init__.py`; no `mistralai.models` subpackage either).
- docs/configuration.md: add `OPENAI_GENERATION_MODEL` and
`OLLAMA_GENERATION_MODEL` rows to the env-var reference table.
- test_mistral.py: add direct unit test for the `_is_rate_limit`
predicate (429 → True, 500 → False, missing-attr → False).
- test_registry.py: stub `mistralai.client.Mistral` in the registry
picker test, mirroring the Ollama sibling, so the test doesn't
depend on the SDK accepting arbitrary keys.

Addresses the Claude Code review on PR #772 plus the SonarCloud S1192 finding:
- Extract `retry_on_rate_limit` into `nextcloud_mcp_server/providers/_retry.py`
as a parametric decorator. OpenAI and Mistral now share the same backoff
loop; future providers can reuse it without copy-paste.
- New `tests/unit/providers/test_retry.py` covers the decorator: 429 retry +
success, non-429 immediate re-raise, MAX_RETRIES exhaustion, default
predicate, and unrelated exception passthrough.
- Tighten Mistral SDK import to `from mistralai.client.errors import SDKError`
(the canonical sub-path; the reviewer's `from mistralai.models import
SDKError` does not exist in mistralai 2.4.5).
- Replace `MistralProvider.close()`'s direct `__aexit__` call with a no-op +
comment — the Speakeasy-generated client has no public close hook and the
underlying httpx client is closed by GC.
- Extract the duplicated "Embedding not supported" message to a module-level
constant (SonarCloud S1192).
- Align `Settings.get_embedding_model_name()` Bedrock check with the registry
by also considering `bedrock_generation_model`.
- Add the `mock_mistral_client` fixture to
`test_mistral_no_embeddings_disabled` for parity with the rest of the file.

Adds a hosted Mistral embedding option (mistral-embed, 1024-dim) alongside
the existing Bedrock / OpenAI / Ollama / Simple providers. Implementation
mirrors OpenAIProvider: lazy dimension detection with a known-models lookup,
chunked batch requests, defensive index sort, and a 429-aware retry decorator.
In the same change, ProviderRegistry switches from os.getenv to the
dynaconf-backed Settings dataclass so all five providers share a single
configuration path. config.py gains the previously-uncovered Bedrock keys,
the new Mistral keys, the missing OPENAI_GENERATION_MODEL /
OLLAMA_GENERATION_MODEL, and SIMPLE_EMBEDDING_DIMENSION.
Auto-detection priority: Bedrock → OpenAI → Mistral → Ollama → Simple.

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.
