radoslav-orlov: "create lossy copies of lossless tracks" only recognized FLAC, even though ALAC/
WAV/AIFF/DSD are now quality-profile formats. the FLAC knowledge was hardcoded in 3 separate
places (the import path, the Lossy Converter scan, and the fix executor) — exactly how a format
gets added in one spot but not another.
kettui-style fix — one canonical seam both sites route through, instead of 3 more string edits:
- new core/quality/lossless.py: is_lossless_format / is_lossless_audio_path (pure; injects a
codec probe for the ambiguous .m4a/.mp4 — ALAC vs AAC — so the decision stays testable with no
I/O), LOSSLESS_FORMATS (single source of truth, derived-consistent with model.tier_score), and
the lossy_output_would_overwrite_source safety invariant.
- create_lossy_copy + the Lossy Converter scan + repair_worker._fix_missing_lossy_copy all route
through it. SQL pre-filters by candidate extensions, then each file is confirmed (probing .m4a).
- SAFETY: a lossy copy must never be written over its own source — an .m4a ALAC source + AAC
target lands on the same .m4a path, and ffmpeg runs with -y. all three sites now bail on the
overwrite case BEFORE ffmpeg (the existing delete-original guard was too late — the source was
already clobbered). dropped a vestigial mutagen FLAC import; updated FLAC-only UI strings.
19 tests: full seam coverage (formats, the .m4a ALAC/AAC probe branch, candidate extensions, the
overwrite guard), a tier-model consistency test that fails if the lossless set drifts, and import-
site wiring tests — WAV now converts (was rejected), and the .m4a-ALAC+AAC overwrite case proves
ffmpeg NEVER runs. 286 quality/import/repair tests green, ruff clean.
diegocade1: DSD files (.dsf, ~500MB DSD64) were labeled "Low Quality" and nagged to upgrade.
two independent causes, both fixed (additive — no existing format/behaviour changed):
1) DSF was an unrecognized format -> bottom 'unknown' tier -> "Low Quality":
- source_map: map .dsf/.dff -> 'dsf' (also lights it up in AUDIO_EXTENSIONS, so Soulseek can
match a DSF if one exists)
- model.tier_score: 'dsf' base 102 (just above FLAC) — lands in the lossless range
- probe_audio_quality: add a DSD branch returning format='dsf' (mutagen.dsf for .dsf detail;
.dff classifies lossless without measured detail) instead of None
- settings UI: DSD in RT_LOSSLESS_FORMATS + a "DSD (DSF / DFF)" option in the profile dropdown
2) the actual cause of the screenshot's findings — the truncation guard falsely called DSF
"broken (only ~12% decodes)": ffmpeg decodes DSD to PCM at a different rate than the DSD
container's 2.8 MHz, so astats samples ÷ container-rate massively under-counts. now
detect_broken_audio skips the truncation check for DSD (silence detection still applies).
8 seam tests: dsf/dff -> 'dsf'; dsf tier in lossless range (with + without measured bitrate);
is_dsd_path; and a contrast pair proving the same 12%-decode numbers flag a .flac but skip a
.dsf. 230 quality/import/silence tests green, ruff + JS integrity clean.
The ranked-target list is now the single source of truth for which formats
download, in the user's exact priority order, for ALL sources — no hardcoded
format hierarchy decides anything. A candidate passes only if it matches a
ranked target; if nothing matches, the existing Use-Fallback toggle decides.
- source_map: new shared format_from_extension() + AUDIO_EXTENSIONS — one
source of truth for extension→format used by every extension-based source, so
adding a format lights it up everywhere. Soulseek now classifies through it
(opus/wav/aiff were previously dropped as 'unknown').
- file_ops.probe_audio_quality (generic import-time guard, all sources): add
WMA; detect ALAC from the real codec (an .m4a is AAC or ALAC).
- soulseek: drop the AAC-specific opt-in gate — AAC now follows the same
universal rule as every format.
- model.tier_score: documented as ONLY a same-format tiebreak + fallback order,
never cross-format priority (the list owns that); add opus/alac bases.
- UI: ranked-target editor offers all formats (FLAC/ALAC/WAV·AIFF lossless with
bit-depth+sample-rate; MP3/AAC/OGG/Opus/WMA lossy with min-bitrate).
- tests: AAC retargeted to the universal model; new coverage for
format_from_extension and matches_target across all formats.

- file_ops.probe_audio_quality: .aiff/.aif were opened with mutagen.wave.WAVE,
which can't parse AIFF — it raised, failed open, and let AIFF silently bypass
the quality filter. Route aiff/aif to mutagen.aiff.AIFF (still the 'wav'
lossless tier).
- test_hifi_preview_guard: _get_hls_manifest gained an expected_duration_s kwarg
and the start tier now comes from quality_tier_for_source (default profile ->
'hires'); accept the kwarg and pin the tier so the chain is deterministic.
- test_quarantine_management: quarantine_group_key intentionally no longer uses
source-specific ids/uri (they break cross-batch sibling matching); assert the
isrc -> normalized-name contract instead.

safe_move_file used shutil.move, which for a CROSS-filesystem move (downloads volume ->
library volume, common in Docker/NAS) copies the file to the FINAL path incrementally. A
media-server real-time watcher (Jellyfin) can catch that partial file mid-write and cache it
with null/incomplete metadata — tracks landing with no disc. Inconsistent because it only bites
cross-fs and races the scan tick; 're-add library' fixes it (rescan reads the now-complete file)
and the on-disk tags are fine — exactly the reported symptoms.
Fix: same-fs uses an atomic os.replace (also overwrites dst); cross-fs copies to a HIDDEN temp
sibling, fsyncs, then atomic os.replace into place (+ temp cleanup on failure). A watcher only
ever sees the COMPLETE file. EXDEV/EPERM/EACCES + the old string check route here, so detection
is strictly broader than before.
Tests: same-fs move, simulated EXDEV routes to the atomic path and leaves no partial temp, helper
completes+cleans, helper cleans temp + preserves source on failure. Existing replace-destination
test still green; 574 imports+relocate tests pass.
get_audio_quality_string now appends the FLAC sample rate so the Downloads
quality chip and library history read e.g. 'FLAC 24bit/96kHz' instead of just
'FLAC 24bit' — surfaces hi-res frequency (44.1/48/96/192kHz) at a glance.

Replaces the Soulseek-only bit-depth heuristic with a source-agnostic
quality system that works across all download sources.
## core/quality/model.py (new)
- AudioQuality dataclass: format, bitrate, sample_rate, bit_depth
- QualityTarget: one ranked entry in the user's priority list
- filter_and_rank(): source-neutral candidate ranking
- rank_candidate(): scores any AudioQuality against ranked_targets
- v2_qualities_to_ranked_targets(): migration helper
## core/download_plugins/types.py
- SearchResult gains sample_rate + bit_depth fields
- audio_quality property returns unified AudioQuality
- AlbumResult gets audio_quality aggregated from tracks
## core/soulseek_client.py
- Parses slskd attributes array (type 4=sample_rate, type 5=bit_depth)
- Real values instead of kbps heuristic
- filter_results_by_quality_preference() replaced by filter_and_rank()
## database/music_database.py
- Quality profile v3 with ranked_targets list
- Auto-migration v2 → v3 on load
- Presets (audiophile/balanced/space_saver) updated to v3
## core/imports/file_ops.py
- probe_audio_quality(): reads actual downloaded file via mutagen
returns AudioQuality with ground-truth values
## core/imports/guards.py
- check_quality_target(): replaces check_flac_bit_depth
checks all formats/sources against ranked_targets
- check_flac_bit_depth() kept as backwards-compat wrapper
## core/imports/pipeline.py
- Uses check_quality_target() instead of check_flac_bit_depth()
- Quality mismatch triggers _requeue_quarantined_task_for_retry('quality')
so next-best candidate is tried before failing (same as AcoustID)

Reported case (CAL): with lossy_copy.enabled=True,
lossy_copy.delete_original=True, and codec=mp3, every download left
both the original FLAC AND the converted MP3 in the target folder.
Users opting into a lossy-only library ended up dual-format on
every import.
Root cause: ``core/imports/file_ops.py:create_lossy_copy`` reads
``lossy_copy.codec`` and ``lossy_copy.bitrate`` from config but never
reads ``lossy_copy.delete_original``. The setting is only consulted
by the pre-move source-vanished check at
``core/imports/pipeline.py:651`` (so the pipeline knows to look for
a lossy variant when the FLAC has already moved on), but no code
path actually deletes the source after conversion.
Fix: after ffmpeg returns success and the QUALITY tag is written,
check ``lossy_copy.delete_original`` and ``os.remove`` the original
when enabled. Belt-and-suspenders:
- Same-path guard (``os.path.normpath(out_path) != os.path.normpath(final_path)``)
prevents accidentally wiping the just-converted file if a future
codec choice somehow resolves out_path to the source path.
- ``FileNotFoundError`` is treated as success (concurrent worker /
dedup cleanup got there first).
- Other ``OSError`` (permission denied, locked file) is logged but
doesn't propagate — the conversion already succeeded, the user just
has to clean up the original manually.
Failure paths skip the delete:
- ffmpeg returns non-zero → returns None, original stays
- lossy_copy.enabled=False → early return before conversion runs
- delete_original=False (default) → original stays
7 regression tests cover honored-when-enabled, kept-when-disabled,
default-keep, ffmpeg-failure-path, lossy-disabled-path, racing-delete,
and locked-file paths. Full pytest 1563 passed; ruff clean.
Note: this PR does NOT address the second bug CAL mentioned (track
re-downloaded despite already existing on disk). That symptom is
caused by stale album metadata on the user's existing files — the
library DB has the track tagged on a different album than the
metadata source reports — combined with wishlist.allow_duplicate_tracks
defaulting to True. Same class of issue partially addressed in PR
fix/watchlist-redownload-and-duplicate-detection but compilation-
album drift is the only currently-handled case. Tracking separately.
slskd appends "_<19-digit unix-nanosecond timestamp>" to a downloaded
filename when the destination already contains a same-named file
(concurrent downloads of the same track, partial-file retries after a
connection drop, cancelled-then-redownloaded files, the same track
surfacing in multiple synced playlists). The file-finder code already
recognized the suffix when matching a download to its source — but
after the canonical file moved into the library, the leftover
"_<timestamp>" siblings sat orphaned in the downloads folder forever.
Reported on Discord by Shdjfgatdif.
cleanup_slskd_dedup_siblings() runs at the end of each successful
import (3 safe_move_file sites in pipeline.py) and prunes any
remaining siblings that strip down to the canonical stem with the
same extension. Conservative match (>= 18 trailing digits) keeps
legitimate filenames like "Track 5" and "Album 1995" untouched. Per-
file unlink failures are swallowed so a single locked file doesn't
block the rest.
17 regression tests cover the suffix-strip primitive, orphan removal,
no-op cases, mismatched extensions, subdirectories, and partial-failure
recovery.
