Draining the queue via Soulseek was stalling: slow peers (~100KB/s) never finished a
full FLAC album within the fixed 10-min timeout, got cancelled at ~89%, and the
fall-through restarted from scratch on the next peer — while single-song folders named
like the album were also being tried.
- Stall detection: abandon a peer with no byte progress for ~90s (queued/dead) instead
of waiting the full timeout; a peer that IS progressing keeps its slot up to a 60-min
backstop, so a slow-but-working transfer can finish.
- Rank search candidates by peer: free upload slot, then speed, then shortest queue.
- Drop candidates with far fewer tracks than the release (single-song folders) up front,
so no download attempt is wasted on them.

With qualityCutoff=3 (want hi-res), a Soulseek-grabbed CD copy stays below cutoff and
is re-attempted for upgrade. Without a guard, when Qobuz is gated by pacing those
attempts would (a) re-search every owned album each monitor cycle and (b) re-download
a same-quality Soulseek copy that keep-if-better discards — pure churn.
Add an upgrade guard: a >= CD-lossless copy can only be improved by hi-res Qobuz, so
when Qobuz is gated, skip the job WITHOUT searching (pre-search skip); and as a safety
net, skip the download when the best-ranked candidate can't beat the existing copy.
Force jobs always proceed. Extracted the shared keep-existing path into a helper.

Two compounding causes of 'many downloads of one album from different sources' in
slskd: (1) the slskd client raised on timeout/error WITHOUT cancelling the transfer
it enqueued, so as the pipeline fell through to other peers each left a transfer
running; (2) the incomplete-download fall-through was uncapped, grinding through
every candidate of a popular album (~200 Soulseek peers), amplified now that Qobuz
pacing pushes most jobs to Soulseek.
- SlskdClient.download now cancels its enqueued transfers (DELETE) on any abandon.
- The download loop caps at _MAX_DOWNLOAD_ATTEMPTS (6) candidates.

Avoid re-triggering a USER_BLOCKED account by capping Qobuz to a human-looking
volume and cadence. A per-album gate (worker/lyra_worker/qobuz_gate.py) allows
Qobuz only within active hours, under today's cap (a warm-up ramp of a steady
cap), and past a randomized spacing since the last Qobuz download; the gap spreads
the day's budget across active hours with jitter. When the gate is closed the
pipeline drops Qobuz candidates so the job falls through to another source (and
monitored albums upgrade to Qobuz later); a Qobuz-only setup is never gated.
Config keys read live each loop; counters reset at the day boundary via the DB
clock. Tunable in Settings -> Qobuz -> Pacing (new /api/qobuz/pacing route).

Completeness/duration verification was applied only to the first candidate that
downloaded successfully; if that copy was incomplete or too short the whole job
failed, even when a later-ranked source had a complete copy (e.g. John Mayer 'The
Search for Everything' — Qobuz reliably fails one hi-res track, so it never fell
back to the deluxe edition or Soulseek).
Extract the checks into a pure _download_problem() and run it INSIDE the download
loop: a candidate that downloads but fails verification now falls through to the
next-ranked source, and the job only fails (needs_attention) when every candidate
is incomplete — reporting the last shortfall reason.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The completeness + duration guards used MusicBrainz's target.track_count /
total_duration_s, but MB picks an arbitrary releases[0] that is often a
deluxe/expanded edition with more tracks (and runtime) than the standard album a
source legitimately delivers. So complete standard-edition downloads were falsely
rejected — The Script 'No Sound Without Silence' (11 vs MB 12) as 'incomplete
download', Skillet 'Unleashed' (12 vs MB's 20-track deluxe) as 'too short'.
Now completeness is judged against the chosen source's own track count
(winner.track_count): a truncated download (fewer files than the source promised)
still fails, and the duration expectation is scaled to the delivered edition's
size. A separate 'implausibly small vs MB' guard (source has <= half MB's tracks)
still rejects a lone-track 'full album' video. Genuine partials (e.g. John Mayer,
a Qobuz track failing mid-download) still correctly fail.

The worker MB resolver picked release groups on (title_ratio, is_album)
and never scored the artist — even though resolve() knows the followed
artist. For a generic title, same-titled release groups by *different*
artists tie on title, and the is_album tiebreak (added in 06e7f91 for
Off the Wall) then actively preferred a foreign Album over the correct
release. Concretely, following Lake Street Dive's "Fun Machine" EP
resolved to an unrelated band "Bastards of Melody"'s same-titled Album,
which then propagated as the downloaded/imported artist.
Make credited-artist similarity the primary sort key, above title and
above is_album. It's a soft signal, never a hard filter, so credited-
name variations (feat., punctuation) still resolve; is_album now only
breaks ties within the same artist+title, preserving the Off the Wall
fix. Verified live: resolve("Lake Street Dive", "Fun Machine") now
returns the 6-track LSD EP.

MusicBrainz search returns release-groups tied on title similarity in an
arbitrary order; `max(groups, key=_ratio)` kept the first, so Michael
Jackson's "Off the Wall" resolved to the 2-track *single* release-group
(Off the Wall / Get on the Floor) instead of the 10-track album. Because
plan_track_names labels files purely by position, that short tracklist got
mapped onto the full album — track 2 became "Get on the Floor" instead of
"Rock with You", and the real "Off the Wall"/"Get on the Floor" files kept
their streamrip names, yielding duplicate titles.
Extract selection into a pure `_best_release_group()` that breaks title-
similarity ties toward primary-type == "Album". Similarity still dominates;
album preference only settles ties. Live-verified: Off the Wall now resolves
to the 10-track album with track 2 = "Rock With You".

A track beyond the MusicBrainz tracklist (a Qobuz bonus track) kept streamrip's
raw name (e.g. "13. John Mayer - St. Patrick's Day (Album Version).flac") while
the main tracklist got clean "## Title" names. plan_track_names now canonicalizes
such extras: strip the leading track-number prefix and a leading "<artist> - ",
yielding "13 St. Patrick's Day (Album Version).flac". Requires an explicit
delimiter after the number so titles like "99 Luftballons" are left alone; with
no tracklist resolved at all the on-disk stem is still kept.

Soulseek's slskd search polls up to ~2 min; searching adapters sequentially
added that on top of Qobuz's instant search. Run the per-adapter searches
concurrently via a ThreadPoolExecutor so total match time is the slowest
single source, not their sum. Only Qobuz drives streamrip's shared asyncio
loop and there's one Qobuz adapter, so no two threads use that loop at once.
Results collected in adapter order (map preserves order) for deterministic
candidate ordering; per-adapter failures still swallowed (down source = no
candidates).

streamrip reports progress only per concurrent track, so Job.downloadProgress
came solely from the file-count poller — 0% until every track landed, then a
jump to 100%. Patch streamrip.media.track.get_progress_callback to aggregate
per-track byte deltas over an estimated album total (avg started-track size ×
len(album.tracks)) into one smooth, generally-climbing 0..1 fraction routed
through the pipeline's on_progress. Capped at 0.99; the pipeline sets 1.0 on
completion. No signature changes — track count read from the resolved album.

ListenBrainz surfaces producers/session players/band members (Max Martin,

they showed as bare rows with an empty page. _derive_albums now drops a
surfaced artist (deletes their pending suggestion) when their MB discography

empty discographies and soundtrack/production-only credits, while keeping real

Discovery seeded only from followed artists. Now it also seeds from artists
you own albums by (LibraryItem.artistMbid, captured since the MBID own-state
work) but don't follow — so your library shapes suggestions, not just your
follows.
- New DiscoverySeed throttle table (migration add_discovery_seed) mirroring
WatchedArtist.lastDiscoveredAt, so each library-derived seed is swept once
per interval (WatchedArtist seeds keep their own throttle).
- _seed_artists merges both seed sources least-recently-swept first, capped at
chunk_size; run_discovery stamps the right throttle per seed and evicts
contributions from seeds that are neither followed nor owned.
- Artists you already have (followed OR owned) are excluded from the suggestion
candidates — discovery surfaces only genuinely new artists.
- discover.seedFromLibrary config (default true) + a Discovery settings toggle.
NOTE: existing LibraryItem rows have null artistMbid (populated on new
import/scan), so a re-scan is needed before old albums seed discovery.

Own-state ("in library") relied on an exact artist-NAME match, so an owned
album whose name differed from the MB canonical (punctuation/locale/feat.)
showed as not-owned even when followed. Capture the MusicBrainz artist MBID
on LibraryItem and prefer it for matching.
- New LibraryItem.artistMbid (migration add_library_artist_mbid). Populated at
import (pipeline) + scan, both of which already hold the resolved target;
the pipeline also now stores rgMbid (it previously didn't). COALESCE on
conflict backfills MBIDs on re-scan without clobbering.
- /api/artists "in library, not followed" matches by artistMbid first, name
case-insensitively as fallback (rows predating the column). Library route
prefers the item's own artistMbid over the release join.
Last.fm/discover own-state still use name-match (they work) — a smaller

The verify step checked track COUNT but not playtime, so a truncated file or
a short preview substituted for a real track could import as "complete". Add
a total-duration check: sum the staged audio's playtime (mutagen) and fail
the job when it falls below 85% of MusicBrainz's expected total
(target.total_duration_s, already resolved). Generous tolerance so
edition/encoding differences don't false-positive; bonus tracks (over-long)
always pass.
The duration reader is injected (measure_duration param, default the real
mutagen-based reader) so the fail/pass paths are unit-tested; it returns None
for the offline fakes (no real audio), skipping the check exactly like the
staged-count guard. worker 233 tests.

_record_contributions now normalizes each source's top-N to [0,1] by its own
top score before summing across sources. ListenBrainz co-occurrence counts
(thousands) no longer drown Last.fm's 0–1 match scores, so a small-scale
source contributes real ranking signal instead of only adding candidates.
Discovery score assertions updated to the normalized scale (single-candidate
fakes normalize to 1.0); added a cross-source test showing a small-scale
source's candidate ranks equal to a large-scale one. min_score is now on the
[0, n_sources] scale (default 0.0 → unaffected). worker 231 tests.

Add Request.force (migration add_request_force): the pipeline's intake now
skips the "already in library" dedupe for a forced job, so an owned album is
re-downloaded. The import step still keeps the new copy only when it's higher
quality, so a forced upgrade can never downgrade what's on disk.
- Worker: _is_force_job → dedupe bypassed when Request.force.
- POST /api/library/[id]/upgrade finds the matching MonitoredRelease and
enqueues a force request (guards against stacking on an in-flight job).
- Library route exposes monitoredReleaseId; the album modal shows a
"Replace / upgrade" button when a release exists.
Worker + web tests added (pipeline force re-acquire; upgrade route).

Add MonitoredRelease.ignored (migration add_release_ignored). The monitor's
enqueue_due skips ignored releases, and they drop off the Wanted list —
independent of `monitored`, so auto-monitor-future can't silently re-grab
an album the user chose to ignore.
- Worker enqueue_due: AND NOT mr.ignored.
- /api/releases/[id] PATCH now accepts `ignored`; /api/wanted filters it out;
artist detail exposes `ignored`.
- UI: Ignore button on Wanted rows; discography shows an "Ignored" badge with
an Ignore/Un-ignore toggle (monitor + search disabled while ignored).

The library scan silently skipped album folders with no MusicBrainz match
(or an unreadable file). Persist them so they're visible and fixable.
- New UnmatchedAlbum model (migration add_unmatched_album), keyed by path.
- scan_chunk records a skipped album as unmatched (reason "no MusicBrainz
match" or "unreadable: <err>"), clears the row when an album later
resolves, and prunes stale rows (a prior scan's, or a removed folder)
when a scan completes.
- GET /api/library/unmatched lists them; DELETE ?id= dismisses one.

Completeness only compared the adapter's self-reported track_count to expected,
so a silently-skipped track (0-byte placeholder — see the Qobuz 24K Magic bug)
imported as a "complete" album. Now the verify also counts the NON-EMPTY audio
actually staged and fails "incomplete download" when fewer than expected are
present (guarded with `staged and ...` so fake adapters that stage nothing keep
using the count path). A real broken download now goes needs_attention (or falls
through to another source) instead of importing a dead track.
Full per-track duration matching against MB recording lengths (the rest of #16)
remains a larger follow-up. worker 224 tests / 7-skip.

docker-compose only health-checked db. Add:

- worker: a background daemon thread touches /tmp/worker.alive every ~15s
(independent of the main loop, so it stays fresh through a long download) +
a compose healthcheck on the file's mtime (unhealthy if >90s stale).
Now `docker compose ps` reports real health for all services.

Bruno Mars "24K Magic" track 1 repeatedly downloaded as a 0-byte file. The
worker log showed the real cause: streamrip's track download hit
HTTPException("got more than 100 headers") — Qobuz's CDN returns >100 response
headers for some tracks and Python's http.client rejects them at the default
_MAXHEADERS=100, so streamrip skips the track and leaves an empty placeholder.
- Raise http.client._MAXHEADERS to 1000 on import of the Qobuz adapter, so those
responses parse and the track downloads.
- _count_staged_audio now skips 0-byte files (a failed-track placeholder is not a
real track) — improves the download-progress estimate and stops counting dead
tracks. (A verify-level "reject 0-byte tracks" safety net is a follow-up under
#16 per-track duration matching — it needs the pipeline fakes to write real
files, deferred to avoid disproportionate churn here.)

Live-testing #9 surfaced a pre-existing gap: one truncated file mutagen chokes
on ("file said 4 bytes, read 0 bytes") raised out of _process_album and aborted
the entire library scan (worklist abandoned). Now scan_chunk catches a per-album
error, rolls back, logs it, counts it as skipped, marks the item done, and
continues — so a single bad file can't block the rest of the library.
worker tests: new case asserts a corrupt album is skipped while a good one still
imports (and captures its on-disk trackNames).

The Library modal showed MusicBrainz's canonical tracklist, hiding incomplete
downloads / edition or track-order mismatches, and showed nothing for albums
without an rgMbid. Now it shows the REAL files on disk.
- LibraryItem gains trackNames String[] (migration add_library_track_names):
the album's on-disk "## Title.ext" audio filenames.
- Captured at import (pipeline._import lists the final album folder) and at scan
(scan._record_owned now also refreshes trackNames on re-scan via ON CONFLICT
DO UPDATE + xmax=0 to preserve the newly-imported flag). New shared
library.list_audio_files() helper.
- /api/library exposes trackNames; the AlbumModal prefers on-disk tracks when
present (parsed "## Title" → position/title, zero network, labeled "On disk ·
N tracks"), falling back to the MusicBrainz listing otherwise. Items imported
before this column show the MB fallback until re-scanned.

A worker crash/restart mid-pipeline left its job stuck in matching/matched/
downloading/tagging with no auto-recovery — only the manual Retry (needs_attention
only) could rescue it. Now on startup the worker resets any such orphaned job
back to 'requested' so it gets re-claimed.
Safe at startup: this fresh worker owns none of those jobs, staging is already
cleared (clear_staging_root runs first), and the pipeline redoes intake→import
idempotently with an atomic import. Terminal jobs (imported/needs_attention) are
left untouched; claimedAt/error/downloadProgress are reset. Logged on startup.

The Floor bar used a file-count poller that jumps 0→~99% for small/fast albums
(streamrip reports only 0/1). But yt-dlp and slskd already emit real byte-level
progress via the on_progress callback the pipeline was discarding
(lambda _pct: None).
- Thread a throttled on_progress → Job.downloadProgress (write on a >=1% move or
every 0.5s; clamped 0..1; write failures swallowed). Called synchronously from
adapter.download on the pipeline thread, so it reuses the main conn safely.
- The file-count poller stays as the FALLBACK: it skips writing while a
`reports` flag is set (an adapter is driving real progress), and the flag is
cleared per attempt so a fall-through to streamrip still gets the estimate.
- Smooth bars for YouTube + Soulseek now; Qobuz/streamrip keeps the file-count
estimate until its per-track callback is hooked later.

The worker's MB browser (discography + artist search, used by monitor sweeps,
library scans, and Last.fm discovery) re-fetched every time. Route it through
the same ApiCache table + logical keys the web app uses, so a discography one
process fetched warms the other, and repeat lookups stop hitting MB.
- apicache.py cached_api(): read-through, serve-stale-on-outage, never caches
null, best-effort (a cache-DB error degrades to a live fetch, never breaks
scan/sweep/discovery). Its own DEDICATED autocommit connection so it can't
commit the worker's in-flight transaction, and autocommit avoids freezing
Postgres now() (which would break TTL math).
- CachingMbBrowser decorates MusicBrainzBrowser, serializing to the SAME
camelCase JSON shape the web writes (round-trip tested). registry.build_browser
wraps it when a DSN is present; the Last.fm source's browser rides it too.
- Hourly prune drops ApiCache rows > 90d so the table stays bounded.

.env.example shipped a valid, PUBLIC base64 key — if a user didn't replace it,
every credential got encrypted with a publicly-known key and everything still
"worked," so the footgun was silent.
- .env.example now ships an obvious placeholder (CHANGE_ME_generate_with_...)
with a "you MUST replace this" note and the openssl hint.
- web + worker validate LYRA_SECRET_KEY at startup: missing / placeholder /
wrong-length ⇒ loud FATAL banner and refuse to start (web via the Next.js
instrumentation hook, worker via _require_secret_key before touching the DB).
The old public example key ⇒ a loud WARNING but not fatal, since an existing
install may have encrypted its creds under it (rotating needs re-entry).
- Validation lives in an edge-safe web/src/lib/secret-key.ts (no node:crypto)
so the instrumentation hook bundles for both runtimes; crypto.ts re-exports.

SlskdClient enqueued the transfer and polled to Completed but never moved any
files into `dest` — slskd saves them to its OWN downloads dir, so staging stayed
empty and every Soulseek job failed "incomplete download". Qobuz/YouTube write
straight into staging and were unaffected.
- SlskdClient._retrieve() moves the finished files out of slskd's downloads dir
into staging after completion, matching tolerantly by basename and preferring
a parent-folder + size match (slskd's on-disk layout varies by version).
- download() returns the moved count as track_count so the pipeline's
completeness check reflects what actually landed; raises loudly if nothing was
found (misconfigured/unmounted downloads dir).
- Downloads dir resolves slskd.downloadsDir Config > SLSKD_DOWNLOADS_ROOT env >
/slskd-downloads default; docker-compose mounts ${SLSKD_DOWNLOADS_DIR} there.
- .env.example documents SLSKD_DOWNLOADS_DIR; retrieval unit-tested offline.
slskd runs as an external daemon, so the shared dir must be a host path both
slskd and the worker mount — set once Lyra runs on the slskd host. Not yet
verified live end-to-end (no slskd access from this VM).

Each search/download called asyncio.run, creating and closing a fresh event loop.
streamrip's module-global download-concurrency Semaphore binds to the loop on first

Adds LastfmSource, resolving Last.fm's often-empty artist mbid via the
injected MB browser (name->mbid cached) so every emitted SimilarArtist.mbid
is a real MusicBrainz artist MBID. Registered in build_similarity_sources,
gated on lastfm.api_key so the ListenBrainz-only path is unchanged when
unset.
Two row-leak bugs found in whole-branch review:
- discovery.run_discovery now prunes DiscoverySeedContribution rows whose
seedMbid is no longer a WatchedArtist (unfollow/removal has no FK cascade)
and recomputes the touched candidates' scores this sweep, instead of
letting a dead seed's contribution inflate the aggregate forever.
- maybe_run_scan's exception handler around scan_chunk now calls
clear_worklist and clears scan.id, matching the drain path. Previously
an exception mid-chunk left the already-done rows plus the remaining
worklist for that scan_id orphaned forever, since the next scan mints a
fresh uuid. Also clear scan.id in the build_worklist failure handler for
consistency.

Replace scan_chunk's O(N^2) tree re-walk-and-skip-to-cursor with a
persisted ScanWorkItem worklist: build_worklist walks the tree once at
scan start and inserts one row per album (idempotent via ON CONFLICT),
scan_chunk pops up to `limit` not-done rows by indexed cursor and marks
them done, and clear_worklist drops the scan's rows once drained.
scan_library is reimplemented on top of the worklist (one-shot scan_id,
drain, clear) with an unchanged signature/behavior. main.py's
maybe_run_scan now drives a generated scan.id through Config
(scan.id/scan.inProgress/scan.progress/scan.result) instead of a
scan.cursor string, so a mid-scan library change no longer risks

Reconciled the pre-existing test_config_from_config_parses_and_defaults
test in test_discovery.py, which referenced max_seeds/maxSeeds and would
otherwise have broken.
Adds a crash-recovery preamble that restores `final` from `.old` when a
prior swap was interrupted after rename(final, old) but before
rename(tmp, final), and always drops stale `.old`/`.importing` orphans.
Also guards the swap: if nothing new was staged into tmp (empty/missing
staging) and `final` already exists, leave it untouched instead of
swapping in an empty copy. This is required beyond the literal preamble
because the pre-existing swap logic unconditionally replaced `final`
with `tmp` regardless of whether anything was actually imported, which
would otherwise destroy a just-recovered (or any existing) copy whenever
staging is empty.
