- 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.

- 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.

Per review:
- Hoist `import httpx` out of the two test function bodies and into
the module imports at the top of
test_astrolabe_chunk_context.py.
- Simplify the regression guard in
test_management_chunk_context_endpoint.py to use
`mock.assert_awaited_once_with(...)` instead of manually unpacking
call_args. This is stricter — it fails loudly on signature change —
and matches the canonical pattern for asserting mock calls.

The /api/v1/chunk-context and /api/v1/pdf-preview handlers in
api/visualization.py forwarded the incoming OAuth bearer directly to
Nextcloud via NextcloudClient.from_token. In multi-user BasicAuth mode
Nextcloud has no validator for those bearers on Notes/WebDAV, so it
treats the request as anonymous and returns 401 — surfaced to the user
as a 500 from /apps/astrolabe/api/chunk-context. Search worked because
it only hits Qdrant.
Architecturally, OAuth is only for Astrolabe→MCP server; MCP server→
Nextcloud always uses the per-user app password stored during provision
(background sync already does this via vector.oauth_sync).
- Resolve the Nextcloud client through get_user_client_basic_auth in
both get_chunk_context and get_pdf_preview, surfacing
NotProvisionedError as a clean 401 instead of opaque 500.
- Apply the same fix to the session-cookie variant in
auth/viz_routes.chunk_context_endpoint for the internal viz UI.
Tests:
- New unit file test_management_chunk_context_endpoint.py, including a
regression guard that asserts get_user_client_basic_auth is awaited
(so reverting to from_token fails without needing a live Nextcloud).
- Updated test_management_pdf_preview_endpoint.py to mock the new auth
path (drops extract_bearer_token / NextcloudClient.from_token patches).
- New integration test test_astrolabe_chunk_context.py drives the full
chain (browser → Astrolabe → MCP → Nextcloud) in multi-user BasicAuth
mode, plus bare-bones 401 checks on the MCP endpoint.
Full unit suite: 546 passed.
Companion PR on astrolabe (cbcoutinho/astrolabe#66) sends the Nextcloud
UID as loginName in the app-password POST body so the stored record is
complete. Submodule bump to that branch will follow once CI reproduces
the failure on the old submodule.
