CubeComming #804: importing Coldplay "Yellow" (the 269s Parachutes album track,
correctly tagged) was quarantined — "Duration mismatch: file is 269.2s, expected
266.0s (drift 3.2s > tolerance 3.0s)". The expected 266s came from a re-resolved
*single* edition, not the file's actual album. The duration-agreement integrity
check exists to catch truncated/wrong slskd TRANSFERS — but a manual import is
the user's own already-tagged file being sorted, so checking it against a
re-resolved release just manufactures false quarantines.
Fix: both manual-import paths (singles + album) now mark the context
is_local_import; the integrity check skips the duration-agreement leg for local
imports via expected_duration_for_check() (new pure helper). The size +
mutagen-parse legs still run, so genuinely broken files are still caught — only
the release-vs-file duration comparison is skipped, and only for manual imports.
slskd downloads are completely unaffected.
This does NOT change the deeper matching (file still groups under Singles vs the
Parachutes album — the #767 canonical-version family); it stops the false
quarantine so the file imports.
Tests: 4 on the helper (local skips, download keeps, zero/None/garbage, string
coercion) + updated the routes context assertion. 557 import/integrity tests pass.
The manual-import routes (album + singles) call post_process_matched_download
directly. When the pipeline quarantines a file — integrity / AcoustID / FLAC
bit-depth — or hits the race guard, it sets a context flag and RETURNS
NORMALLY (it only marks the task failed + notifies when there's a task_id,
which manual imports don't have). So the inner pipeline raised no exception,
and routes.py counted `processed += 1` for a file that had just been moved to
ss_quarantine, not the library. Result: the UI shows a green "Done" while the
track silently vanished — exactly the #764 report (Coldplay - Yellow.flac ->
ss_quarantine, but "Done").
The download path already handles this in
post_process_matched_download_with_verification (it reads the same flags and
marks the task failed); only the manual-import routes were missing the check.
Fix: new pure helper import_rejection_reason(context) returns a human-readable
reason for any terminal rejection (_integrity_failure_msg / _acoustid_quarantined
/ _bitdepth_rejected / _race_guard_failed) or None for a clean import. Both
manual-import routes now consult it: album_process reports the track in
`errors` instead of counting it processed; process_single_import_file returns
("error", reason) instead of ("ok", ...). Verified every move_to_quarantine
call site (4, all in pipeline.py) sets one of those flags, so no quarantine
path slips through. This also delivers the "direct display of the error" the
reporter asked for — the reason now surfaces in the response `errors` list.
Does NOT address the reverse symptom ("failed even though it moved correctly")
— not yet root-caused — nor the separate bit-depth hole on the download-path
wrapper.
Tests: tests/imports/test_import_rejection_reason.py (10) — each trigger
detected, falsy flags ignored, deterministic ordering, plus two route-level
tests driving the REAL process_single_import_file (quarantine -> "error";
clean -> "ok").
Import album search silently fell through to the next source in
METADATA_SOURCE_PRIORITY when the configured primary returned zero
matches — intentional behavior shared with the auto-import worker
(see core/auto_import_worker.py:1316). With MusicBrainz selected and
a query MB couldn't resolve, users saw Deezer cards with no indication
their primary was bypassed.
Backend now echoes `primary_source` on /api/import/search/albums,
/api/import/search/tracks, and /api/import/staging/suggestions.
Frontend renders a per-card 'via {source}' badge when the served
source differs from the primary, plus a banner above the grid when
every card came from a fallback source. Fallback semantics unchanged.
Also collapses an inline duplicate of _renderSuggestionCard inside
importPageSearchAlbum into a single shared renderer.
Regression test pins the contract: response carries primary_source +
per-album source when the chain falls back.
Move the remaining manual import endpoint logic out of web_server.py and into core.imports.routes behind ImportRouteRuntime. The Flask endpoints now stay as thin compatibility wrappers for album/track search, album match/process, single-file import processing, and batched singles processing.
Keep legacy test patch points intact by re-exporting build_album_import_match_payload from web_server and routing singles_process through an injected process_single_import_file callable. This preserves existing route-level monkeypatch behavior while keeping the extracted helper testable.
Add focused helper coverage for Hydrabase enqueueing, search limit clamping, album match payload forwarding, album import side effects, single-file worker outcomes, malformed manual matches, and singles aggregation/injected-worker behavior.
Verification: py_compile and git diff --check passed locally; bundled-Python smoke covered the extracted helpers. Claude reran the project tests and reported all tests passing.
Move import staging files/groups/hints/suggestions controller logic out of web_server.py and into core.imports.routes behind an ImportRouteRuntime dependency object. Keep the existing Flask routes as thin compatibility wrappers so the UI endpoint surface stays unchanged.
Add focused tests for staging file filtering, album grouping, hint generation, cached suggestions, empty missing staging paths, and error payloads from failed path/metadata reads.
Verification: py_compile passed for web_server.py, core/imports/routes.py, and tests/imports/test_import_routes.py. A bundled-Python smoke pass covered the extracted helper behavior; pytest was not available in this Windows shell because the bundled Python lacks pytest and the repo venv is WSL/Linux-only here.
