* fix(playback): throttle legacy bridge-hit recording; emit loop-set for manual A/B
window.feedBack.getLoop() is a read surface plugins legitimately poll
(note_detect HUD ticked it at ~30 Hz), but every call recorded a
playback.loop-api bridge hit: compat-shim bookkeeping, a
playback:bridge-hit event, and a diagnostics snapshot rebuild +
stringify per call — real main-thread cost and a saturated hitCount in
the capability inspector, even with no song playing.
- _recordPlaybackBridge now throttles per bridgeId|surface (5 s window).
Bridge hits are a 'surface still in use' signal, not a call counter.
- setLoopEnd() (manual A/B buttons) now emits the same loop-set
transport event as setLoop(), so event-driven consumers no longer
need to poll getLoop() to see button-armed loops.

* feat(drums): capture velocities alongside times in unmapped-percussion reporting
Both drum converters opt-in out_unmapped capture (convert_drum_track_from_midi,
convert_drum_track_to_drumtab) gain an index-aligned `velocities` list next to
`times`, carrying each dropped note real dynamics — MIDI velocity verbatim; GP
velocity with the same 1-127 gate as mapped hits, falling back to the 100
import default. A hand-mapping UI (the editor unmapped-notes dialog) can then
restore mapped notes at their source dynamics instead of flattening to v:100
(editor-side consumer: feedBack-plugin-editor#111).
The GP path chronological sort now reorders times and velocities in LOCKSTEP
so multi-voice measures cannot silently reassign dynamics. Additive: callers
that ignore the new key are unaffected.
Tests: extended tests/test_midi_import_drums.py + tests/test_gp2rs_drums.py
(alignment, lockstep sort, out-of-range fallback) — 26 passing.

* docs(gp2rs): clarify velocity-default comment, mark dead-path fallback
- The mapped-GP velocity comment conflated GP's authoring default (95,
Velocities.default) with the drumtab render default (100,
DEFAULT_VELOCITY in lib/drums.py) used when `v` is omitted. Clarify
both defaults and that only the latter applies to omitted hits.
- Mark the `else: times.sort()` fallback in the unmapped-percussion
time/velocity sort as belt-and-suspenders — times and velocities are
always appended together under the same len<100 guard, so lengths
can't actually diverge.
No behavior change; comment-only maintainability nits from PR review.

* feat(library): sort and badge by personal difficulty rating
Adds sort=difficulty/difficulty-desc to the library API (correlated
subquery over song_user_meta.user_difficulty, unrated songs pushed to
the bottom either direction, same pattern as the existing mastery
sort) and surfaces the rating as a badge on library cards in both the
v2 grid/tree views and the v3 grid. The rating itself already existed
(song_user_meta) — this just makes it sortable and visible, so it's
no longer only readable in the per-song edit drawer.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
* fix(library): escape difficulty badge, wire tree view, add changelog+tests
- Wrap song.user_difficulty in esc() at both badge call sites
(static/app.js ~2082 and ~2283) for XSS-consistency with the
sibling tuning badge, which already uses esc().
- server.py: query_artists (the classic tree view's data source, used
by /api/library/artists) never batch-attached user_difficulty the
way query_page does for the grid, so the tree-view difficulty badge
added in 75673c3 was unreachable dead code (song.user_difficulty was
always undefined there). Now attaches it via the existing
user_meta_map() helper, same pattern as query_page.
- Add an [Unreleased] CHANGELOG.md entry for the difficulty sort +
badge feature, matching the repo's existing entry format.
- Add tests/test_library_filters.py::test_difficulty_sort_pushes_unrated_to_bottom
asserting unrated songs sort to the bottom in both sort=difficulty
and sort=difficulty-desc directions, and
::test_tree_view_songs_carry_user_difficulty covering the
query_artists fix above.

passes every song across up to 50 artists, which could push the
placeholder count past SQLite's older variable limit; query_page's
small pages are unaffected. (CodeRabbit: Stability & Availability)
- Rebuild static/tailwind.min.css: the ◆N difficulty badge introduced
bg-blue-900/30 + text-blue-300, which were never compiled into the
committed stylesheet, failing the tailwind-fresh CI gate.

* feat(keys_highway_3d): sharp-layout modes, lane-color opacity, octave lines
Add a Highway layout section to the settings with a rebuilt way to draw
sharps/flats and lanes on the 3D piano highway:
- Sharps & flats layout (keys3d_bg_sharpMode): floating (original raised
plane), flat (one plane, zero-overlap piano-shaped tiled lanes with the
naturals evened out), and realistic (one plane, bars sized like the
physical keys). All geometry lives in pure laneSpanFlat()/laneSpanReal()
helpers. Default: realistic.
- Lane color opacity (keys3d_bg_laneOpacity, 0-1): fades the pitch-class
lane tint; at 0 it is a dark floor with guide lines only at the key-block
boundaries (E-F and each octave), toward 1 full vivid colored lanes. The
strips, per-lane separators and block lines crossfade with the value.
Default: 0.
- Octave separators (keys3d_bg_octaveGaps, default on) and Octave line
contrast (keys3d_bg_octaveContrast, 0-1): the B->C octave line is a dark
layer scaled by lane opacity plus a bright layer scaled by its inverse,
so it auto-shifts dark->bright as the lanes fade.
Settings re-read on init() so they apply on the next chart build. All other
behavior (MIDI scoring, palettes, camera, themes, hit feedback) is unchanged.
Unit tests cover the new defaults, the sharp-mode setting, and the lane
geometry (tiling/evening for flat, uniform/overlap for realistic).

laneSpanFlat() trimmed a white key's edge for its neighboring black
key's lane even when that neighbor midi fell outside
range.activeLow..range.activeHigh — the neighbor's lane is never
drawn (see the activeLow/activeHigh skip around the lane-strip loop),
so the trim left a dark, unfilled sliver at the active-range boundary
with no sharp lane to fill it. Gate the trim on the neighbor being
in-range; callers that don't pass a range (e.g. the raw-tiling unit
tests) keep the prior unconditional-trim behavior.
Also add the CHANGELOG entry for this PR's feature set, following the
existing keys_highway_3d wording convention (no plugin-local
CHANGELOG exists; plugin.json was already bumped 0.1.2 -> 0.2.0 by

convert_midi_track_to_keys_wire builds its own inline tempo map and
divides by the raw midi.ticks_per_beat at two sites (the tempo-table
precompute and the tick_to_seconds closure). A malformed header with
division == 0 raised ZeroDivisionError, and an SMPTE division (which
mido returns as a NEGATIVE signed short) produced negative/garbage
note times.
Guard the divisor with `ticks_per_beat if ticks_per_beat > 0 else 480`
so both the zero and negative cases fall back to the SMF default. The
`> 0` form (not `or 480`) is required because a negative value is
truthy and would slip past `or`. Positive-division behavior is
unchanged.
Follow-up to #796, which fixed the same class of bug in the newer
convert_midi_tempo_map / _build_tick_to_seconds path.
Adds two focused tests: division == 0 no longer crashes and emits a
non-negative time, and a negative/SMPTE division yields sane
non-negative times.

* feat(midi): convert_midi_tempo_map — extract tempos, time signatures, beat grid
The keys/drums MIDI converters always built a tempo-aware tick->seconds
map internally (to bake note times) and then discarded it — and never
read time_signature meta at all — so every MIDI import landed with no
bars, no measures, and an implied 4/4 no matter what the file said.
New lib/midi_import.py helper convert_midi_tempo_map(midi_path,
track_index) extracts the grid a .mid actually carries:
- tempos: {time, bpm} per tempo event (deduped per tick, 120 default)
- time_signatures: {time, ts: [num, den]} — the song-timeline shape
- beats: one row per beat on the editor grid shape — numbered downbeats
with a den hint, measure:-1 interior beats; the beat unit follows the
active signature (6/8 = six eighth-note rows per bar)
Event scope mirrors _build_tick_to_seconds: SMF type 0/1 merge meta
from all tracks, type 2 reads ONLY the chosen track (independent
timelines — callers must never share one grid across type-2 tracks).
Mid-bar signature events (ill-formed but seen in the wild) apply at the
next bar boundary. All times compute from absolute ticks through the
cumulative tempo table and round once at emit — rounding error never
accumulates with song length. A bar-count safety valve guards malformed
files. Consumer: the editor's multitrack MIDI import (tempo-seed
dialog, feedBack-plugin-editor roadmap Phase 3).
Tests: tests/test_midi_tempo_map.py — 10 cases driving the REAL
function against real .mid files built with mido (no stubs): default
grid, tempo bends, 500-bar rounding-drift check, 4/4->3/4 and 6/8
signatures, mid-bar signature deferral, duplicate-tick last-wins,
type-2 meta isolation from a bogus sibling track, empty files, grid
coverage bounds. Full MIDI-adjacent suite green: 55 passed
(test_midi_tempo_map + test_midi_import + test_midi_import_drums +
test_gp2midi) under the project venv.

* fix(midi): make convert_midi_tempo_map robust — real division guard, symmetric tempo default, single-pass meta
- Push the ticks-per-beat fallback into _build_tick_to_seconds (the single
place ticks route through), guarding on `> 0` so a division==0 (malformed)
or negative SMPTE-division header no longer raises ZeroDivisionError or
walks the beat grid into negative times. Mirror the guard at the
convert_midi_tempo_map beat_ticks site. The local `or 480` was cosmetic
before — the closure still divided by the raw division.
- Seed tempos_out with a 120 BPM row at time 0 when the first set_tempo
lands after tick 0, symmetric with the (0, 4, 4) time-signature default,
so the sidecar matches the grid the head of the song actually used.
- Collapse the duplicated meta_source/note_source lists into one
source_tracks walked in a single pass (meta collection + end_tick).
- Fix a weak assert in test_mid_bar_signature_applies_at_the_next_boundary
(operator-precedence `(A and B) or C`) to assert den == 4 outright.
- Add tests: non-positive division (0 + negative SMPTE), first tempo after
start seeds 120@0, explicit SMF type-0 file, and the _TEMPO_MAP_MAX_BARS
safety valve.

`injectPlayerButton()` anchored the injected Tuner button with
`controls.querySelector('button:last-child')`, which can match a NESTED
button that is not a direct child of `#player-controls`. `insertBefore(btn,
nestedButton)` then throws `NotFoundError` (the reference node must be a
direct child); since injection runs from the tuner's `screen:changed`
handler, the throw propagated out of the player-screen transition and
stalled its render. The v3 path was already safe (plugin-control slot);
only the classic anchor was bad.
Use `:scope > button:last-of-type` (direct child only) with a
`parentNode === controls` guard before insertBefore, falling back to
appendChild. Bump plugins/tuner 1.3.3 → 1.3.4.
Test: tests/plugins/tuner/js/inject_player_button.test.js — extracts the
real function and runs it over a faithful DOM model whose insertBefore
enforces the direct-child invariant; the nested-last-button case reproduces
the throw on the old anchor and passes on the new one (5 tests).

The feedpak spec (§7.1) defines the lyrics_source vocabulary as {authored, transcribed, user}, but the reader only accepted the legacy {xml, notechart, whisperx, user} set and silently downgraded anything else to "xml". A spec-compliant writer (e.g. the stem_splitter plugin, which emits transcribed for WhisperX-produced lyrics) therefore lost its provenance badge.
Widen the allowed set to the union of the spec vocabulary and the legacy values so both validate, and alias the legacy whisperx engine name to the spec transcribed so existing packs normalise to the spec badge.

The v3 Settings "Save" button posts dlc_dir together with demucs_server_url,
default_arrangement and av_offset_ms in one request. POST /api/settings
validated dlc_dir first and early-returned "DLC directory not found" before it
ever processed demucs_server_url, so on a machine whose DLC path doesn't resolve
(fresh install, unplugged/network drive, a path carried over from another
machine) setting the Demucs server address silently failed — reported in
got-feedBack/feedBack-demucs-server#3 (macOS 07-05 nightly).
- server: a non-resolving dlc_dir is now recorded as a warning and skipped
rather than aborting the whole POST, so the co-submitted keys still persist.
The bad path is surfaced via a new additive `warnings` field and folded into
`message` so the settings status line still shows it.
- client (v3): the Demucs input now autosaves on blur/enter via a single-key
persistSetting POST, like every other v3 setting, so it never depends on the
coupled Save button.

* feat(keys_highway_3d): add note-colour palettes and selectable camera angles
Give the 3D keys highway player-facing view options and a tuned default
look, so the piano highway is readable out of the box and customisable
from the settings panel without touching code.
Note colours (settings -> Note colours, `keys3d_bg_palette`):
- Octaves (new default): each octave its own hue climbing the rainbow,
darker sharps, so pitch height reads at a glance on any note range.
- Rainbow: the original per-pitch table (colours unchanged).
- Vivid / Pastel: per-pitch variants.
- Emerald / Ice: single-hue two-tone (uniform naturals, darker sharps).
The pick drives the notes, key glow, lane guides and hit flames, live.
Camera (settings -> Camera angle, `keys3d_bg_camera`):
- Classic (the original low rig) / Elevated / Overhead (new default).
- Height, distance and tilt fine-tune sliders nudge the base vantage the
auto-pan/zoom follow-motion orbits; presets apply live.
The new defaults are opinionated for plug-and-play (octaves palette,
overhead camera, tilt -0.6); anyone who prefers the original look can
pick Rainbow + Classic. Settings changes are re-read on init() so they
apply on return from the settings screen, not only after a relaunch.
Scoring, hit-timing and MIDI handling are untouched -- these are purely
visual. Numeric FX keys clamp to declared ranges (FX_RANGES); the pure
colour/camera helpers are covered by unit tests (node --test).

* fix(keys_highway_3d): make Classic camera reproduce the original rig + drop per-frame camera alloc
Review follow-ups on the palettes/camera feature:
- "Classic" preset now reproduces the historical rig exactly. The tuned
plug-and-play downward aim (camTilt -0.6 x CAM_TILT_UNITS = -33) is baked
into CAM_PRESETS.overhead.lookY, and camTilt now defaults to 0 (neutral).
The default overhead look is byte-identical (effective lookY still -33),
but "pick Classic for the original look" is now actually true instead of
leaving a -33 down-tilt applied. settings.html tilt slider defaults to 0.
- _rig() writes into a hoisted reusable object instead of allocating a fresh
{y,z,lookY,lookZ} literal every frame, honoring the module's documented
"no per-frame allocations in draw()" discipline. Callers read it
synchronously and never retain it, so one shared instance is safe.
Tests updated for the neutral camTilt default; adds an invariant test that
the default overhead framing is unchanged and Classic + neutral tilt == the
historical LOOK_Y. Full JS suite green (1069 pass).

The cover picker only offered CAA covers from a song's MATCHED release, so an
unmatched song (the city-pop pile) got nothing but Current/Pack/Upload/URL. Add
a search box: GET /api/song/{fn}/art/cover-search?q= searches MusicBrainz
release-groups and returns each album's CAA front-250 thumb; the picker renders
them as pickable tiles (same apply→/art/url path; covers with no CAA art
self-hide). Pre-filled from the song's artist + album/title (romaji fallback), so
a blank-artist pack pre-fills "Junko Yagami …". Reuses the throttled _mb_http_get.
* feat(v3 library): click a "No match" badge to fix it — batch → popup handoff
Connects the two halves: the "No match" badge (the unmatched pile) now opens the
Fix-metadata popup for that song in one click, instead of right-click → menu.
The resting badge becomes interactive (pointer-events-auto + hover), carrying a
data-meta-fix hook; wireCards opens window.__fbFixMatch(playTarget) on click and
stops propagation so it doesn't also play the card. Batch tile states stay
non-interactive. Loop becomes: Unmatched filter → see the pile → click one →
fix it. tailwind.min.css regenerated for the badge's hover classes.
* feat(v3 library): show the author's romaji, not blank/native script (English base)
Two changes so an English-speaking base never sees a blank name or native script:
- Filename romaji fallback: a blank-artist CDLC pack ("Artist_Title_v1_p") shows
nothing useful (artist blank; title = the raw filename), and a match fills it
with kanji/kana. query_page + pack_fields now surface the author's own romaji
parsed from the filename ("Junko Yagami — BAY CITY") when the pack has no
artist of its own — display-only, keyset-safe (raw title stashed for the
cursor), a real pack artist or a user override still wins.
- Smart adopt: "Use these values" now KEEPS the readable romaji name + title the
card already shows and takes only album/year/genre (+ art via the pin) from the
match, so identifying a Japanese song gives "Junko Yagami — BAY CITY — FULL MOON"
with the right cover, never native script.
Tests: romaji fallback fires for a blank-artist CDLC pack (grid + pack_fields
agree) and is left alone when the pack has a real artist.
librosa.sequence.dtw's default step sizes permit pure horizontal/vertical
moves; on songs whose chroma is self-similar for long stretches the flat
cost surface let the path collapse (minutes of score onto one audio frame),
so auto-sync produced monotonic-but-garbage sync points and the per-bar
warp imported charts badly out of sync while reporting success.
Use the standard music-sync step pattern [[1,1],[1,2],[2,1]] (local tempo
ratio bounded to 0.5x-2x), falling back to unconstrained steps if the
global length ratio makes it infeasible.
Validated on the reported song (138 BPM tab, YouTube audio): coarse points
now track 1:1, refine holds slopes 0.77-1.04, warped downbeats hit onset
peaks at 3.3x background energy.

Switching the active window / alt-tabbing away (most often on Windows) can
trigger a GPU context reset. The 3D highway's WebGL renderer had no
webglcontextlost handler, so a lost context was left to escalate into a
render-process crash -- matching the intermittent "randomly crashes when I
change windows" desktop reports.
The renderer now binds webglcontextlost/webglcontextrestored on its own WebGL
canvas (ren.domElement): the loss is preventDefault()'d so the browser keeps the
context restorable, draw() bails while the context is down so no GL work runs on
a dead context, and on restore the viewport is re-applied and rendering resumes
(Three re-uploads scene resources on the next frame). Listeners are removed in
teardown.
Root cause is a strong hypothesis -- the crash is intermittent and
unreproducible -- but the fix is low-risk and additive and closes a real gap:
there was no context-loss handling anywhere in the renderer.
plugins/highway_3d 3.31.2 -> 3.31.3. Tests:
tests/js/highway_3d_context_loss.test.js (source-contract, like the other
highway_* tests). The sibling keys_highway_3d / drum_highway_3d renderers share
the same gap -- follow-up in their repos.

Adds a one-click preset to the shared "Highway String Colors" picker,
next to the existing Okabe-Ito "Colorblind-friendly" preset. Contributed
by a deuteranopic player who found the Okabe-Ito set still hard to
separate: it retunes the six main strings and keeps that set's 7/8-string
colors. Applies to both the 2D and 3D highways via the shared picker,
which writes the slot->hex map the renderers already consume.
Additive frontend-only change to HWC_PRESETS in static/app.js; the picker
UI and both highways pick it up automatically (the preset list is
generated from HWC_PRESETS and applied by id). All 20 highway
string-color JS tests pass; app.js syntax-checks clean.

Adds Genre as a fifth Details field (edit / lock / revert / Yours-Pack
provenance), backed by the existing override store. To make it actually useful,
the genre FILTER and FACET now resolve the per-song override (effective genre =
override else scanned pack genre) — guarded so the common no-override case stays
on the plain indexed column — so a corrected/added genre is immediately
browsable. Genre stays a library-only overlay: it is NOT a write-to-file field
(split WRITE_FIELDS = the four file-safe fields from the five DETAIL_FIELDS), so
Write to file leaves the genre override in place and the copy says so. The
Match→Details bridge also carries a candidate's first genre.
Tests: effective-genre facet + filter, and that a value-less lock doesn't invent
an effective genre.

Connects the popup's two tabs. A match only improves the underlying canon+art;
by design it never silently re-titles the grid. This adds the explicit opt-in
path: each Match candidate (search or Identify-by-audio) gets a "Use these
values →" action that copies its title/artist/album/year into the Details tab
as pending (unsaved) inputs and lands you there for review — pinning the match
too so the art/canon follow. You then Save (overlay) or Write to file. Queue-
review candidates are unchanged (they still accept/pin on click).

* feat(library): "Write to file" in the Fix-metadata popup's Details tab
Completes the confirmed edit model: Save keeps edits as a reversible display
overlay (files untouched); "Write to file" bakes the shown title/artist/album/
year into the pack itself via the existing POST /api/song/{fn}/meta (writes the
manifest, re-stats, coalesces a rescan). On a real file write the now-redundant
override values are cleared (locks kept) and the tab re-renders, so the fields
read from the file as "Pack". Loose-folder / unwritable packs fall back to a
DB-only update and say so (may revert on a full rescan). Secondary button next
to Save; touches only the four file-safe fields, the rest of the pack verbatim.

* fix(library): mirror server year coercion in Write-to-file grid sync
update_song_meta coerces a non-numeric/empty year to "" before persisting,
but writeToFile optimistically set song.year to the raw typed text — so the
library card flashed e.g. "abcd" until the next natural refresh. Apply the
same integer coercion client-side so the in-memory song matches what was
written.

* feat(library): metadata override + lock store, enforced by enrichment (popup slices 1–2)
Backend foundation for the Fix-metadata popup. Not yet surfaced in the UI (the
display + 3-tab popup are the next slices); no PR until it's user-visible.
Slice 1 — the store:
- `song_field_override(filename, field, value, locked)` table: a reversible
DISPLAY overlay (never written to the pack), filename-keyed so it survives a
rescan (never purged by delete_missing) and is dropped only with the song.
- DB methods (partial upsert that drops empty+unlocked rows; batch map) +
`GET`/`PUT /api/song/{fn}/overrides` (field allowlist title/artist/album/
year/genre; clearing rides PUT since DELETE /api/song/{path} shadows sub-
routes; PUT demo-blocked).
Slice 2 — locks respected by enrichment:
- The auto-matcher composes a per-song `_compose_lock_filter` onto the global
apply-filter, so a match still applies IDENTITY (mbid/release → art) but never
re-canonicalizes a LOCKED display field.
- Gap-fill (write-to-file) skips locked album/year/genre — writing the matched
value would be exactly the clobber the lock exists to prevent.
- Review/manual picks bypass the filter (an explicit confirm overrides a lock).
Tests: store semantics + rescan-survival + API; the lock filter + reader; an
auto-match leaving a locked field un-canonicalized; gap-fill excluding locked
keys.

* feat(library): show per-song overrides in the grid (popup slice 3)
The grid now displays the user's per-song title/artist/album/year override
in place of the pack value ("grid shows only overrides") — a matched
MusicBrainz canon never silently re-titles a card; canon stays in the
Details drawer + art. Overlaid in Python over the visible window, keyset-safe
like the P4 artist-alias re-label: the seek still runs on the raw column, and
the one overridable keyset column (title) stashes its raw value for the cursor
so paging never skips/dupes. The private stash is dropped from the payload.

* feat(library): 3-tab Fix-metadata popup — Details / Cover art / Match (slice 4)
Turns the thin single-song fix-match modal into the Plex-style metadata
editor reached from a card's "Fix metadata…" menu:
- Details tab: type + lock the displayed title/artist/album/year. Values
ride the reversible override store (GET/PUT /api/song/{fn}/overrides); each
field sits on its pack value (Yours/Pack provenance + revert-to-pack), a lock
pins it against auto-match, and Save repaints the grid via library:changed
(slice-3 overlay). This is the real tool for the blank-artist city-pop pile
MusicBrainz can't surface — you just type the right title.
- Cover art tab: hands off to the shared image picker (its own modal); the
pick refreshes the thumbnail everywhere.
- Match tab: the existing MusicBrainz search + candidate/pick flow, refactored
into shared body/footer helpers (the queue-review flow is untouched).
Backend: GET /overrides now also returns the pack baseline so the Details tab
can pre-fill + show provenance. tailwind.min.css regenerated (build-tailwind.sh)
for the popup's new utility classes.
Identify-by-audio (AcoustID) is deferred: it lives in unmerged PR #759, off
main — the Match tab gains the button once #759 lands and this branch rebases.

* fix(library): wire "Identify by audio" in the tabbed popup's Match tab
The AcoustID Identify button (#759) merged in referencing an out-of-scope
`panel` in the wiring — a leftover from the pre-popup fix-match modal that my
tab refactor renamed to `root`. Under strict mode that threw, so the handler
never attached and the button did nothing. Scope it to `root` (the tab body),
which is where the search-results area it renders into lives.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(library): make "Identify by audio" outcomes unmistakable
An empty AcoustID result read the same as a broken button. Each state now says
plainly which outcome it is — ✓ fingerprinted-but-no-match vs no-audio vs off vs
unavailable — and, in the popup, points at the manual fallback (Search, or set
the album in Details + cover in Cover art by hand). A ✓ marks the states that
actually ran, so "worked, found nothing" no longer looks like a failure.

* feat(v3 library): persistent "no match" badge + Unmatched quick filter
The Refresh-Metadata batch (#764) shows a transient per-tile "no match" only
while a pass runs, so the unmatched pile goes quiet at rest. Two additions make
it visible + reachable:
- Persistent per-card "No match" badge: query_page now marks each row
`unmatched` (a cheap failed-set membership like favs/estd), and enrichBadge
paints a subtle resting marker for those cards — tracked in a `_unmatched` set
so a batch tile clearing falls back to it instead of wiping it. A live batch
tile still wins while a pass runs.
- "Unmatched" toolbar toggle (local-only): one click applies the same filter as
the drawer's Match → Unmatched (match_state='failed'), so the no-match pile is
a click away right after a batch. Re-queries + reflects active state.
Test: query_page flags a failed row + the match=unmatched filter returns it.

* fix(v3 library): repaint persistent no-match badge after metadata tile-clear
_clearMetaTiles removed every .v3-meta-tile node — including the new
persistent 'No match' resting badge, which derives from _unmatched rather
than _metaTile. A metadata rescan's tile-clear therefore dropped the badge
until the next scroll re-rendered the card. Repaint it from _unmatched.

* feat(gp_autosync): piecewise time-warp helpers + refine_sync onset pass
auto_sync computes per-bar sync points but consumers only ever applied the
scalar bar-1 audio_offset, so any tempo drift between the recording and the
tab's authored tempo accumulated over the song. Add the librosa-free helpers
needed to apply the full piecewise mapping:
- bar_start_times(gp_path): per-bar score times sharing auto_sync's axis
(GPIF bar-resolution map, GP3/4/5 per-tick integration)
- build_warp_anchors(points, bar_starts): monotonic (score, audio) anchors
- warp_time(t, anchors): piecewise-linear map with edge-slope extrapolation
- warp_song_times(song, warp): retime a lib.song.Song in place (notes,
sustains, chords, beats, sections, anchors, handshapes, phrase levels,
tone changes, tempo overrides)
- gp_has_expandable_repeats(gp_path): detects GP3/4/5 repeat/volta/direction
markup whose playback expansion auto_sync's as-written points cannot map
Also implement refine_sync() — the editor's refine-sync endpoint has imported
it since the snapshot but it never existed in lib, so the Refine button 500'd.
It densifies the DTW points to every Nth bar and re-times each with a local
onset phase sweep (radius clamped under half a beat to avoid one-beat locks,
short scoring grid + median residual snap against the first beats). Synthetic
click-track validation: ~13ms mean / ~40ms max error from ±180ms coarse input
across 117-123 BPM recordings of a 120 BPM tab.

* feat(enrichment): loose MusicBrainz search fallback (find aliased artists)
The MB text search used a strict field-phrase query
(`recording:"<title>" AND artist:"<artist>"`). A field phrase only matches
MusicBrainz's *primary* artist/title — it never searches ALIASES — so a
recording stored under a non-Latin primary name (大橋純子) whose romanized
form ("Junko Ohashi") is only an alias returns ZERO results, even though MB
has it. Whole swaths of a community library (e.g. romanized J-pop / city-pop
charts) were unsearchable.
- `build_recording_query(..., loose=True)` drops the field scoping + phrases
for plain AND-ed term groups (`(telephone number) AND (junko ohashi)`),
which searches the whole document incl. aliases.
- `_mb_search_recordings` runs the strict query first (unchanged, high
precision) and only on an EMPTY result retries once with the loose query —
so mainstream matches are untouched and the extra throttled request is spent
only on a miss. Results are re-scored by rank_candidates, so recall goes up
without lowering match quality (auto-accept still needs the per-field floors).
Verified live: "Junko Ohashi / Telephone Number" and "Anri / Windy Summer"
(both 0 under the strict query) now surface the real records; "AC/DC /
Highway to Hell" still hits strict at score 1.0 with no loose retry.
Follow-up (separate): alias-aware SCORING so these can auto-confirm, not just
appear as manual candidates.

* feat(enrichment): alias-aware scoring (auto-confirm non-Latin-primary artists)
Builds on the loose-search fallback: that surfaces a recording stored under a
Japanese primary name (大橋純子) via its romanized alias, but the SCORER still
compared the reference ("Junko Ohashi") against the primary only → artist
similarity 0 → below the auto floor, so it could only ever be a manual
candidate, never an auto-fill.
- mb_match: `cand_artist_sim` takes the best similarity over the candidate's
primary name AND its `artist_aliases`; score_candidate + classify use it.
- server: `_mb_artist_aliases(id)` fetches an artist's aliases (one throttled
lookup, process-cached — a one-artist discography costs ONE request) and
`_alias_enrich` attaches them ONLY to promising near-misses (title agrees,
primary artist doesn't) so a normal pass spends zero extra requests. Wired
into both the auto-matcher (_enrich_one) and the manual search proxy.
Verified live: "Junko Ohashi / Telephone Number" → 大橋純子 candidate goes from
score 0.5 (loose-only) to 1.0 (auto-confirmable), ranked #1; "AC/DC / Highway
to Hell" unchanged at 1.0 with no alias lookup.
Stacks on #771 (feat/mb-loose-search-fallback).

* fix(enrichment): keep live exclusion in the loose search fallback
The loose fallback dropped the strict path's -secondarytype:Live filter, so a
studio chart whose strict query missed could fall back to — and, since
score_candidate doesn't penalize live takes, auto-confirm — a live-only
recording. Apply the same live gate to the loose query (skipped only when the
source title is itself a live take).

Every real Guitar Pro 6 (.gpx) file failed to import with
"GPX BCFS sector pointer out of range (malformed file)".
A real .gpx's BCFZ-declared decompressed size isn't 0x1000-aligned, so
its last (small) container file lands in a partial trailing sector.
_parse_bcfs raised whenever a sector read would run past the buffer
end, rejecting the whole container before score.gpif could be extracted
-- so no GP6 file could be charted in the song editor. (GP7/GP8 .gp
files take the ZIP path, not BCFS, which is why this wasn't caught
earlier.)
Clamp the final sector read to the buffer end (the per-file size field
trims the padding anyway), matching canonical GPX readers (alphaTab /
PyGuitarPro). A sector whose start is past the end still raises, so the
malformed-file guard is preserved.
Verified against two real GP6 files -- both now unpack to valid GPIF
with all tracks. Adds the previously-missing positive BCFS round-trip
coverage: partial-final-sector, multi-file, sector-aligned baseline,
and the preserved out-of-range guard.

The virtualized v3 Songs grid rebuilt its entire visible window
(grid.innerHTML = _renderCardsRange(...) + a full wireCards pass) every
time it slid by one row. Each row-boundary crossing was therefore a heavy
synchronous frame — reparse ~60 cards, re-attach hundreds of listeners,
reflow — that stalled the main thread and buffered held-arrow key-repeats,
flushing them in a burst. Testers saw the library "go super fast for a
second then slow down," skipping "every so many scrolls," up or down, at
the same spots each time. It hitched scrolling back up over already-loaded
songs too, because the cost was DOM teardown, not fetching.
renderWindow() now reconciles the window in place: it reuses the card
nodes that stay on-screen and builds only the row that enters/leaves
(~6 nodes per slide instead of ~60). Nodes are keyed by absolute index
(data-idx) with a real-vs-skeleton + select-mode signature (data-sig) so
hole-fills after a page fetch and select-mode toggles still rebuild
exactly the nodes that changed. wireCards()'s existing data-wired guard
then wires only the freshly-built nodes, so per-slide listener churn drops
with it. Everything keyed off data-fn (favorites, ⋮ menu, right-click,
selection, accuracy badges, A–Z rail) is unaffected.
Follow-up to the stage-2 virtualized grid (#636 item 3). Frontend-only.
Tests: tests/js/v3_songs_window_recycle.test.js — window stays [start,end)
contiguous and in-window node identity is reused across a down-then-up
scroll; select-mode toggle and a rail-seek jump rebuild correctly.

Adds a media-server-style "Refresh Metadata" control to the Songs toolbar
(beside "⟳ Refresh") — the metadata counterpart to a file scan.
- Re-matches the songs currently SHOWN (the visible grid window) against
MusicBrainz: a per-view refresh that's visible even on an already-matched
library. The button doubles as Stop while a pass runs; a batch progress bar
+ per-tile queued→working→done badges show what's happening. User-pinned
`manual` matches are never re-matched.
- Backend: POST /api/enrichment/{cancel,states,rematch}; /status gains
total/matched/current/cancelling; a cooperative cancel Event is checked
between songs in the match + art phases so Stop halts without waiting for
the whole queue. `states` is read-only (open); `cancel`/`rematch` are
demo-blocked.
- Matcher: when a pack's `artist` field is blank (common in community
charts), derive artist/title from the CDLC `Artist_Song-Title` filename
convention as a SEARCH SEED so text matching can identify it — the displayed
values still come only from the confirmed MusicBrainz match, nothing
estimated is shown as author-set. Rescues blank-artist packs that otherwise
always failed.
Tests: enrichment_states_for, the three new routes, cancel-halts-a-pass,
kick-clears-stale-cancel, filename parse, blank-artist seeding, and
present-artist-not-overridden.

* feat(enrichment): AcoustID audio-fingerprint identification (opt-in)
Text search can only guess the version; the definitive fix is content-based —
fingerprint the actual audio with Chromaprint (fpcalc) and look it up on
AcoustID, which maps the fingerprint to the EXACT MusicBrainz recording (the
approach Lidarr uses). Sidesteps the studio-vs-live ambiguity entirely.
- lib/acoustid_match.py: pure response parsing + config gating (unit-tested);
normalizes AcoustID hits into the same candidate shape as mb_match so the
review UI + editor Match popup render fingerprint and text hits identically.
- server.py: _fpcalc (Chromaprint subprocess), _acoustid_lookup (throttled,
offline-guarded HTTP), _identify_by_fingerprint (also available to the
library-enrichment pipeline), and POST /api/enrichment/identify (upload the
master audio → candidates).
- Fully OPT-IN and graceful: absent the fpcalc binary or an ACOUSTID_API_KEY
the whole path is a no-op / 503 and the text matcher runs unchanged.
Requires (both optional): the `fpcalc` (Chromaprint) binary on PATH/$FPCALC,
and a free AcoustID application key in $ACOUSTID_API_KEY. Pure parsing/gating
is unit-tested; the fpcalc + live-lookup path needs those two to exercise.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(enrichment): make AcoustID self-serve — opt-in toggle + API key in settings
Fingerprinting was env-var only (ACOUSTID_API_KEY), so only an operator could
enable it. Add two core settings so a user can turn it on themselves:
- acoustid_enabled (bool, default OFF — opt-in)
- acoustid_api_key (string, ≤128 chars, trimmed; env var stays a fallback)
_acoustid_available()/_acoustid_lookup() now resolve (enabled, key) from
settings via _acoustid_settings(). /api/enrichment/identify distinguishes
"not set up" (412 needs_setup — the UI nudges the user to enable it) from
"set up but fpcalc/network missing" (503) so the client never fakes a match.
Verified: default off; POST round-trips + trims; 412 vs 503 gating; bad
types/over-length rejected. acoustid_match unit tests green (8/8).
* fix(enrichment): POST the AcoustID lookup instead of GET
A Chromaprint fingerprint is multi-KB (a 3.5-min track ≈ 3.5k chars), so
sending it as a GET query param overflows the request URL for longer songs and
fails spuriously. AcoustID accepts the same params form-encoded — POST them.
* fix(acoustid): space-separate the lookup `meta` (was silently dropping metadata)
The meta value was `+`-joined ("recordings+releasegroups+compress"). Sent over
the wire the literal `+` percent-encodes to %2B, which AcoustID does NOT split
into flags — so every hit came back with an empty `recordings` array and the
parser produced zero candidates (a fingerprint match that resolved to nothing).
AcoustID wants the flags space-separated. Verified against real fingerprints:
`+`-joined → 0 recordings; space-joined → 28, resolving Highway to Hell and
Living After Midnight to their canonical studio albums as the top hit.
* feat(acoustid): resolve the canonical original album + year from the fingerprint
AcoustID hits resolved the right recording but a weak album/blank year: the
album picker took the first studio-typed group (a later comp/soundtrack typed
"Album" could win) and the year took an arbitrary release (often a reissue).
Request the `releases` meta (which carries per-release dates) and use them to
(1) pick the EARLIEST original studio album among the groups and (2) fill the
year from that album's earliest release. Verified against real fingerprints:
Smoke on the Water → Machine Head (1972) not a later comp; Highway to Hell →
1979; Living After Midnight → British Steel (1980). +2 unit tests.
* feat(acoustid): per-song "Identify by audio" for the library metadata tooling
Add POST /api/enrichment/identify/{filename} — fingerprints an EXISTING library
song's own master audio (resolves the sloppak's original_audio or a loose
folder's audio), the library counterpart to the upload-based /identify used by
the editor. Wire an "Identify by audio" action into the match-review / Fix-match
modal: it renders fingerprint hits in the same candidate list and pins the pick
via the existing /review/{f}/pick. Shared _acoustid_gate() (412 needs_setup /
503) for both endpoints; 404 when a pack has no full mix. Both identify routes
added to the demo-mode block list (they spend fpcalc + the AcoustID budget) —
fixes a pre-existing miss on the upload route.
* fix(acoustid): regenerate stale tailwind CSS + cap identify upload
- static/tailwind.min.css was stale vs a fresh rebuild (ci/tailwind-fresh red);
regenerated with the pinned tailwindcss@3.4.19 (byte-stable).
- /api/enrichment/identify read the whole multipart upload into memory before
writing it; stream it to the temp file with a 256 MB cap (413 over) so an
oversized upload can't balloon RAM. fpcalc reads from the temp file anyway.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* feat(acoustid): pre-parse upload guard + settings UI to enable it
- /api/enrichment/identify is now async: a pre-parse Content-Length check +
request.form(max_part_size=…) reject an oversized body BEFORE Starlette spools
the multipart to temp disk (mirrors the song-upload endpoint), and the blocking
fpcalc subprocess + AcoustID HTTP run off the event loop via run_in_executor.
- The v3 Metadata-matching settings card gains an 'Identify by audio' opt-in
toggle (acoustid_enabled, default OFF) + an AcoustID key input
(acoustid_api_key), wired in match-review.js — so the advertised feature is
reachable from the UI instead of only via a manual settings POST. Reuses
existing classes only; committed tailwind.min.css stays fresh.

* fix(enrichment): rank the canonical studio take over live/comp versions
A flat MusicBrainz /recording text search ties every take of a song at the
same score, so "AC/DC — Highway to Hell" returns a wall of live bootlegs and
compilations with the 1979 studio version buried (or below the fetch limit).
- build_recording_query: drop live-ONLY recordings (`-secondarytype:Live`).
Compilations are deliberately kept — they REUSE the studio recording, so
filtering them cuts the very recording we want (verified against MB).
- _best_release / parse_recording_doc: pick the canonical studio album
(primary Album, no Live/Compilation/Remix/... secondary type) for the
displayed album/year, and expose a `studio` flag.
- rank_candidates: since the combined score caps at 1.0 (perfect text match
ties), break ties on the studio flag and — when the caller knows the audio
length — on duration proximity, so the studio take wins over live/extended
cuts. The studio distinction is intentionally NOT scored (a live take is
still the right SONG), only re-ordered.
- /api/enrichment/search: accept an optional `duration` param so a caller that
has the audio but no library row (the editor's create modal) can pass the
master-track length for the duration tiebreak.
Verified end-to-end against live MusicBrainz: AC/DC "Highway to Hell" now
returns the 1979 studio recording at #1 with the correct album + year.

* fix(enrichment): official releases outrank unofficial studio albums
_best_release sorted (clean, status_ok, date), so an UNofficial bootleg Album
outranked an official Single/EP/comp — regressing canonical album/year and
seeding cover-art from a bootleg for single-only songs. Order status_ok before
clean: official first, then prefer a clean studio album among the official
releases (still surfaces the studio album over an official live/comp album).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
* fix(enrichment): keep live recordings for genuinely-live charts
build_recording_query unconditionally added -secondarytype:Live, but denoise()
strips a '(Live at …)' qualifier from the query — so a chart that IS a live take
had its only correct recording filtered out (both background enrichment and
manual search). Skip the live filter when the source title carries a
parenthetical live marker; a bare title word ('Live and Let Die') still filters.

* fix(enrichment): drop the studio tiebreak when the chart is a live take
Follow-through on keeping live recordings for live charts: rank_candidates still
ranked the studio take ahead of a tied live one, so a live chart would auto-match
the studio recording. Skip the studio tiebreak when the source title has a live
marker — duration proximity + score then pick the right live version.

* fix(settings): profile-aware saves/resets/switch, provider tunings, bass-5
Five regressions from the instrument-profiles rework:
1. save_settings canonicalized profiles on EVERY save -> empty/unrelated POST
froze default profiles into config.json (broke
test_empty_post_preserves_all_existing_keys). Gate on the save touching
instrument settings; GET already virtualizes profiles.
2. pathway is profile-mirrored, so the Gameplay reset (flat-key delete) was a
no-op. reset_settings now resets pathway inside the persisted profiles too.
3. Per-profile tuning validation rejected provider/custom tunings (tuner
plugin, /api/tunings). _valid_tuning_for_key now accepts a name unknown to
every built-in table while still rejecting a built-in misapplied to the
wrong key.
4. First-migration overwrote an explicit active_instrument_profile with the
legacy-inferred one, so a fresh-config switch to 'bass' was lost. Use
setdefault so an explicit request wins.
5. Pre-existing test_instrument_fields_persist used bass-5 + 'Drop D' (a
4-string tuning). Updated to the valid 'Drop A'.

* fix(settings): partial-merge instrument_profiles; clamp tuning on string-count switch
Two partial-update follow-ups:
- save_settings normalized a POSTed instrument_profiles by FILLING every omitted
profile with defaults and replacing wholesale, so a one-profile update reset
the others. Validate each PROVIDED profile individually and merge the partial
over the persisted set inside the lock — /api/settings is partial-merge.
- the string-count picker posted only string_count, so the backend silently
reset a now-invalid tuning to Standard while the UI kept the old value
(settings/tuner desync). Clamp + post the valid tuning too, mirroring the
instrument-switch path.

* fix(library): serve art/load songs mounted through a library junction
A song library mounted through a directory JUNCTION/symlink subfolder (a
library shared across app installs; the desktop app's own mounts) had broken
album art and couldn't load: the scanner's rglob follows the junction and
indexes the songs, but _resolve_dlc_path (via safe_join's .resolve()) followed
the junction to its real target, saw it outside DLC_DIR, and rejected every
song reached through it → 403 on /art, 404 on /art/candidates, broken covers.
- _resolve_dlc_path now uses LEXICAL containment (os.path.normpath, no symlink
following) so an in-library junction is allowed, while `..` traversal and
absolute paths are still rejected (the traversal tests pin this).
- safe_join is left STRICT (.resolve()-based) — it is the zip-slip / plugin-
asset / avatar guard, where following a symlink out IS the defense — but
gains an explicit NUL guard (on Python 3.13/Windows resolve() no longer
raises on an embedded NUL, so the byte was leaking through; strictly-more-
rejection, no effect on the zip-slip contract).
Tests: test_dlc_junction (junction allowed; `..`/absolute/NUL rejected; the
safe_join-stays-strict contrast). Existing traversal/safepath/art-candidates
suites stay green.

* fix(library): reject Windows drive-letter paths in _resolve_dlc_path
The new test_absolute_path_rejected pins 'C:/Windows/system32/x' → None, but on
POSIX a drive-letter path isn't absolute, so Path(dlc)/'C:/…' becomes the
contained relative dir '<dlc>/C:/…' and slipped through the lexical containment
check (red on the Linux CI). Not an escape, but the traversal contract should
hold cross-platform (a shared library is reached from either OS). Reject a path
that is absolute or drive-qualified in either POSIX or Windows semantics before
the containment check. Legitimate relative/junction paths are unaffected.

Two commits (delete beethoven-ode_to_joy, re-add The Adicts' Ode to Joy) never
updated _BUILTIN_STARTER_SOURCES: it still listed the deleted pack and omitted
the added one. The listed-but-missing file made the all-present gate never fire,
so NO starter content seeded on first run — and the on-disk-but-unlisted pack
would bundle as dead weight. Both starter-seed guard tests were red on main,
reddening ci/test on every core PR. Sync the manifest to disk.

The previously pinned BtbN autobuild release (2026-06-19) was pruned
upstream, so the release build's curl download 404'd (exit 22).

Add two more public-domain starter songs alongside Für Elise, wired into
_BUILTIN_STARTER_SOURCES so they seed into DLC_DIR/starter/ on first run:
- The Star-Spangled Banner (lead) — John Stafford Smith; cleaned the "Unknown"
artist / placeholder album, author "Fee[dB]ack".
- Ode to Joy (lead/rhythm/bass + drums) — Beethoven. Replaces the raw
"Ode to Joy (VST Cover)_The Adicts.feedpak" that was committed to main but
never added to the seed list (so it bundled 23 MB of dead weight and never
appeared). Fixed metadata (artist Beethoven, year 1824, author "Fee[dB]ack"),
and repointed the stem from the 22 MB editor WAV to the byte-identical-render
full.ogg (both exactly 85.324 s), shrinking the pack 23.8 MB -> 1.7 MB.
Add guard tests asserting every _BUILTIN_STARTER_SOURCES entry has its file
committed and that a seed run lands them all — this catches exactly the
listed-but-missing (or committed-but-unlisted) mismatch that left Ode to Joy
un-seeded.

Ship a public-domain Für Elise (keys) feedpak as starter content so a fresh
install isn't an empty library. server._seed_builtin_starter_content() copies
bundled packs into DLC_DIR/starter/ exactly once, guarded by a marker in
CONFIG_DIR — unlike the always-reseeding diagnostic seed, a user who deletes
the starter song does not get it back. `starter/` is deliberately outside the
diagnostics/tutorials library carve-out so the song surfaces as a normal
library entry.
Extract the shared symlink-safe, mtime-aware copy loop into
_copy_builtin_packs() and route both the diagnostic and starter seeds through
it (diagnostic behavior unchanged; existing tests green).

* fix(plugins): don't treat transient absence from /api/plugins as uninstall
The backend clears its plugin registry at the start of load_plugins()
and repopulates it incrementally while HTTP stays up, so every backend
restart (desktop: Audio Quality soundfont switch, LAN toggle, update
restart) serves a window of partial — even empty — /api/plugins
responses. loadPlugins() treated absence from the current response as
an uninstall, with three destructive consequences for still-loaded
plugins:
1. Their settings-panel and screen DOM were wiped while their
_loadedPluginScripts entry survived, so the NEXT refetch failed the
DOM-existence check and re-evaluated the plugin's screen.js
mid-session. For the desktop audio_engine plugin that re-ran init()
against the surviving native audio chain and exactly duplicated
every VST/NAM/IR stage (the alpha testers' "chain duplicates after
leaving the Audio menu" / blown-out gain reports).
2. _reconcilePluginStyles dropped their stylesheet, leaving them
visible but unstyled until they reappeared.
3. The stale-contribution sweep unmounted their UI contributions and
unregistered their capability participant with no re-registration
path (plugin scripts don't re-run thanks to the loadedScripts
guard).
Absence is now a non-signal everywhere in loadPlugins: the DOM wipe and
style reconcile are scoped to plugins the response actually names, and
the absence sweep is removed. Present plugins still fully re-sync via
_registerLegacyPluginUiContributions each round; failed plugins are
present in the response and still cleaned up; nav is rebuilt from the
response so genuinely uninstalled plugins drop out of it, and their
(un-unloadable) already-evaluated scripts keep their DOM until reload.

* test: update idempotence contract to the absence-is-not-uninstall invariant
The removed-plugin sweep contract pinned the old behavior this branch
deletes; pin the new invariant instead (no absence sweep + respondedIds
scoping on the DOM/style reconcilers).
