Song audio (/audio/{f}), the local-audio-path resolver (/api/audio-local-path),
and raw sloppak-member serving (/api/sloppak/{f}/file/{rel}) — plus the shared
_resolve_sloppak_local_file helper — move to lib/routers/media.py. Bodies verbatim
except @app->@router and the cache/static path seams (AUDIO_CACHE_DIR->
appstate.audio_cache_dir, STATIC_DIR->appstate.static_dir, SLOPPAK_CACHE_DIR->
appstate.sloppak_cache_dir — all already in the seam). No new slots.
The two test fixtures that redirect STATIC_DIR to a temp dir now also patch
appstate.static_dir (the moved routes read the seam, not server's global).
server.py: 2,638 -> 2,507 (-131).
Verified: pyflakes clean; route set identical (143), all unique-path (no
catch-all, no shadowing); full pytest 2395 passed (the audio-local-path +
sloppak-file-traversal cases). eslint 0. Boot smoke: /audio, /api/sloppak/{}/file

The 14 /api/enrichment/* routes — status, kick/cancel, per-song state, the
Match-Review queue (accept/reject/pick/search/rematch/refresh/states), and the
AcoustID fingerprint identify endpoints — plus the route-exclusive candidate

The library query surface (songs/albums/artists/stats/genres/tuning-names/
practice-suggestions), the provider list/art/sync endpoints, and collection CRUD
move to lib/routers/library.py. The registry itself — LibraryProviderRegistry,
LocalLibraryProvider, SmartCollectionProvider, the collection-provider lifecycle
(_sync/_unregister_collection_provider), and the shared query/collection helpers
(_library_filter_args, _split_csv, _sanitize_collection_rules, _safe_art_redirect_url,
the filter-key sets) — moves to lib/library_registry.py.
The PLUGIN CONTRACT is untouched: server.py still constructs the singleton
(LocalLibraryProvider needs meta_db), still exposes register_library_provider /
unregister_library_provider to plugins via plugin_context (with the per-plugin
ownership scoping in plugins/__init__.py), and injects the registry + local
provider into appstate. The router reads appstate.library_providers /
appstate.local_library_provider at call time; the provider classes are duck-typed
so no plugin imports a base class. Acyclic: library_registry imports
routers.art (for LocalLibraryProvider.get_art) + appstate, never server.
server.py: 3,692 -> 2,925 (-767).
Verified: pyflakes clean; ORDERED route table identical set (library block mounts
at one site — all exact/specific-path, no catch-all, no shadowing); full pytest
2397 passed (incl the plugin register/unregister + collection-as-provider tests).
eslint 0. Boot smoke: /api/library + providers list "local"; a created collection
surfaces as a `collection:N` provider through the seam; collection CRUD clean.

Upload/delete, the catalog-metadata write-back, user-meta, overrides, gap-fill,
and the per-song info payload (11 routes) move to lib/routers/song.py with their
exclusive helpers (the atomic upload commit + the song-IO lock, the upload caps,
the gap-fill proposal builders). Bodies verbatim except @app->@router and the
seam reads: meta_db->appstate.meta_db, art_override_paths->appstate.art_override_paths,
and the scan/ingest helpers that stay in server.py (the scan lifecycle owns them)
-> new appstate seam callables: kick_scan, invalidate_song_caches, stat_for_cache,
and scan_status() (a getter — the underlying dict is reassigned). The gap-fill
MBID/ISRC regexes are reached as enrichment.X; _MULTIPART_OVERHEAD_SLACK (shared
with the staying AcoustID-identify route) moves to lib/enrichment.py beside
_ACOUSTID_MAX_UPLOAD_BYTES.
ROUTE ORDER: song_router mounts AFTER art_router — get_song_info's catch-all
`/api/song/{filename:path}` would otherwise shadow `/api/song/{path}/art*`
(Starlette matches first-registered; the :path converter is greedy).
server.py: 4,478 -> 3,692 (-786).
Verified: pyflakes clean; ORDERED route table preserves the specific-before-catch-all
invariant; full pytest 2397 passed (incl the art/cover 304 + CAA-fetch tests that

* refactor(server): move the metadata-enrichment subsystem into lib/enrichment.py (R3)
MusicBrainz / Cover-Art-Archive / AcoustID transport, the match-scorer glue, and
the background enrichment worker (~930 lines, 61 defs) leave server.py as one
cohesive unit. Bodies are verbatim; the only changes are seam reads:
meta_db / config_dir / sloppak_cache_dir / art_cache_dir -> appstate.<slot>
_song_pack_art_exists / _art_override_paths (stay in server.py for the art +
delete routes) -> appstate.<callable> (new seam slots, injected by reference)
_env_flag -> env_compat.env_flag_compat (the existing identical helper)
_artist_title_from_filename -> imported from metadata_db (its home)
the User-Agent VERSION lookup: Path(__file__).parent ->
Path(__file__).resolve().parents[1] (lib/enrichment.py -> app root)
server.py drives the worker through the module (import enrichment; the routes +
scan lifecycle call enrichment.X). Tests that faked the network on `server`
(_mb_http_get, _enrich_network_enabled, _caa_http_get, ...) now patch the same
names on `enrichment` — the module attribute is resolved at call time, so one
setattr reaches both the routes and the worker's internal callers. Acyclic:
enrichment imports appstate/appconfig/dlc_paths/metadata_db/mb_match/
acoustid_match/sloppak/loosefolder, never server.

* test: reset enrichment worker state between tests (CodeRabbit)
lib/enrichment.py now owns the worker, and it stays imported for the whole
session while the `server` fixtures pop-and-reimport `server` — so the cancel
Event / status dict / caches would leak across tests, and a stale `_enrich_cancel`
could short-circuit a later direct `_background_enrich()`. An autouse conftest
fixture clears that process-global state before each test.

* test: tighten the enrichment-reset fixture (CodeRabbit)
Narrow the import guard to ImportError (not blind Exception, BLE001), and stop
clearing _caa_index_locks — it's guarded by _caa_index_locks_guard, so an
unlocked clear() would race a still-alive worker, and its per-release mutexes
carry no test state.

The merged-tuning-catalog route moves to lib/routers/tunings.py, verbatim except
@app->@router, CONFIG_DIR->appstate.config_dir, and the two seam substrates it
needed:
- lib/appconfig.py — the pure config.json reader `_load_config` (used by ~11
server sites + future config-reading routers). server.py re-imports it, so
those call sites and any `server._load_config` test reference are unchanged.
- appstate.tuning_providers — the TuningProviderRegistry instance injected by
reference (a stable object mutated in place via register()/unregister()), so
the router reads the same registry plugins populate through plugin_context.
The instance stays defined in server.py, so `server.tuning_providers` still
resolves — zero test retargets.
The tuning constants (DEFAULT_REFERENCE_PITCH, TUNING_PRESET_MIDIS,
freqs_to_midis) already live in lib/tunings.py and are imported directly.
server.py: 6,960 -> 6,917.

The three /api/diagnostics/* routes (export, preview, hardware) plus their
exclusive payload-cap helpers and the `_diag_*` normalisers. Bodies verbatim
except @app->@router, CONFIG_DIR->appstate.config_dir, _running_version()->
appstate.running_version() (a new seam slot; the impl stays in server.py where
the settings region also calls it), and the builtin-plugins lookup in
_diag_plugins_roots: Path(__file__).parent -> Path(__file__).resolve().parents[2]
(routers -> lib -> app root; plugins/ ships at the app root in every packaging
path).
The pure caps/normalisers (_diag_cap_console/_dict/_contributions,
_diag_coerce_bool, _diag_normalize_include, _DIAG_MAX_*) are re-exported from
server.py so the existing `server._diag_*` / `server._DIAG_*` tests keep
resolving — none of them monkeypatch these, so no test retargets.

* perf(harness): add 2D-highway frame-time measurement + capture the R3c gate (H0)
scripts/perf-baseline.mjs gains a `--song` mode: it wraps requestAnimationFrame
before any page script, TAGS the frames the highway actually painted (via
highway.addDrawHook), starts playback, and reports draw-frame p50/p95/p99 over
`--frames` seconds across `--runs` runs. Tagging is the point — ~half the rAF
callbacks are other cheap loops (~0.1 ms); averaging them in would hide a
renderer regression, so only draw frames are counted.
This is the metric the plan says gates the highway.js split (R3c) but the harness
never measured (it did server latency + boot + heap only, and the R0 numbers were
against an empty library). docs/perf-baseline.md now records the pre-lift baseline
on the Arcturus feedpak: p50 ~2.2 ms, p95 spread 2.7-3.2 ms across 3 runs. The
H-container lift (next) re-runs this on the same box and must stay within noise.
Maintainer/CI-only tooling; the existing no-`--song` run is unchanged.

The single largest handler in server.py — the 902-line /ws/highway/{filename}
chart streamer — plus its 3 exclusive helpers (_pick_smart_arrangement,
_sanitize_authors, _sanitized_song_offset). server.py: 9,008 -> 8,003 (-1,005,
the biggest single R3 cut).
Clean move despite the size: the handler's only server-module deps are the 4
path constants + 3 exclusive helpers + app + log. Everything else it uses is
either NESTED inside the handler (_evict_audio_cache, _fill_scale_degree,
_manifest_entries, _tone_names, _xml_rank, _send_keepalives) or imported from
the shared lib modules (song/audio/sloppak/drums/notation/dlc_paths/metadata_db).
- Path constants read through the appstate seam: added static_dir /
sloppak_cache_dir / audio_cache_dir slots (config_dir already there);
server.py configures them. Bodies otherwise verbatim (@app.websocket ->
@router.websocket, PATHS -> appstate.*, log -> module logger).
- sloppak_cache_dir IS setattr-patched, so the 3 test_highway_ws_* suites now
also `setattr(appstate, "sloppak_cache_dir", ...)` next to their existing
server patch. _sanitize_authors unit tests import it from routers.ws_highway
(it moved). No other test churn.
- Removed 23 now-dead imports from server.py (song/audio/drums/notation/
bisect/contextvars/structlog/WebSocket*/_arr_smart_sort_key) — diffed against
the origin/main unused-import baseline so only NEWLY-dead ones went.
owns_tmp (assigned, never read) moved verbatim — it's pre-existing dead on
origin/main too; left as-is to keep the move faithful.
Verified: route table identical to origin/main (143, paths/methods/order);
handler body verbatim spot-checked; pyflakes clean (server has no new
undefined/dead); pytest 2400 passed; packaging guard 53; eslint 0. Boot smoke:
the highway WS streams the full chart (song_info/beats/sections/notes/chords/

The keystone for the path-dependent routers (ws_highway, song, audio-local-path,
sloppak): the "where do the song files live + safe containment" layer leaves
server.py so a router can reach it.
- `_resolve_dlc_path` (pure — args only) moves verbatim.
- `_get_dlc_dir` reads the env-derived paths through the appstate seam
(appstate.dlc_dir/dlc_dir_env/config_dir) instead of module globals, so
lib/dlc_paths.py does no import-time IO.
- appstate gains `dlc_dir`/`dlc_dir_env` slots (config_dir already there);
server.py configures them. All three are env-derived, so a setenv+reimport
fixture reconfigures them for free — ZERO setattr retargeting.
- server.py RE-EXPORTS both (`from dlc_paths import _get_dlc_dir,
_resolve_dlc_path`), so its 24+16 call sites AND the tests that reach
`server._get_dlc_dir()` / `server._resolve_dlc_path()` directly
(test_dlc_junction, test_highway_ws_*) resolve unchanged — no test edits.
server.py: 9,085 -> 9,008.

The biggest router yet — 12 playlist routes + custom covers — and the first that
needs the config-path seam. server.py: 9,302 -> 9,085 (-217).
Three causally-linked pieces, all required for playlists:
- `config_dir` joins the appstate seam (the plan always put the path constants
there; deferred in S3, needed now). It's env-derived, so the ~49
pop-and-reimport fixtures reconfigure it for free — ZERO setattr retargeting.
STATIC_DIR/SLOPPAK_CACHE_DIR (patched via setattr) stay in server.py until a
router that reads them is extracted, and get retargeted then.
- `_clean_str` (pure request-field sanitizer, 14 callers) -> lib/reqfields.py;
server.py imports it back. Unblocks wanted/saved/collections/profile/... later.
- routers/playlists.py: bodies verbatim, `@app`->`@router`, `meta_db`->
`appstate.meta_db`, `CONFIG_DIR`->`appstate.config_dir`, `_clean_str` from
reqfields, `_ART_CACHE_HEADERS` as a local const (art keeps server.py's).
The two exclusive cover helpers (_playlist_cover_path/_url) move with it.
include_router at the original site; full 143-route table identical to
origin/main. One test retarget: test_playlists_api called
`server._playlist_cover_path` directly -> now imports it from routers.playlists
(reads appstate.config_dir, which the `server` fixture configures).
Verified: pyflakes clean; route table identical; pytest 2401 passed (28 in
playlists+collections+appstate); packaging guard 51 (auto-picked up reqfields);
eslint 0; boot smoke drives create/rename/add-song/cover-upload/serve/delete —

The packaged desktop app died at startup:
File ".../Resources/slopsmith/server.py", line 71, in <module>
import appstate
ModuleNotFoundError: No module named 'appstate'
feedback-desktop's scripts/bundle-slopsmith.sh copies a HARDCODED list of core
files into the bundle -- server.py, VERSION, lib/, data/, static/,
plugins/__init__.py. The root-level appstate.py (#833) and routers/ (#834)
shipped fine in Docker, passed every test, and were silently dropped from the
packaged app.
Both now live under lib/, the one core directory every packaging path already
copies wholesale -- Dockerfile `COPY lib/`, docker-compose.yml, and the desktop
bundler's `cp -r lib` -- and that all three put on sys.path (on Windows via the
embeddable-Python ._pth, where PYTHONPATH is ignored: build-windows.sh writes
`../slopsmith` and `../slopsmith/lib`). No feedback-desktop change and no new
release are needed for this to take effect.
lib/ is also the CORRECT home under Principle V, and always was once the design
settled: with the injection seam, appstate.py constructs nothing and does no
import-time IO, and a route module only builds an APIRouter. The premise that
forced root placement -- "appstate opens sqlite at import" -- stopped being true
when configure() replaced ownership. The Dockerfile / .dockerignore /
docker-compose.yml entries added for the root layout are reverted; nothing else
in core changes (git mv, so --follow survives).
tests/test_packaging.py is the guard: it walks server.py's module-level imports,
keeps the ones resolving inside this repo, and fails if any lives outside a
directory the packagers copy -- with the ModuleNotFoundError spelled out. So the
next root-level core module can't ship broken. Negative-checked: restoring
appstate.py to the root fails it; the message names the file and the four
packaging files a root module would have to teach.
(It also has to skip `origin in {"built-in","frozen"}` -- on 3.14 the frozen
stdlib reports origin="frozen", and Path("frozen").resolve() lands inside the
repo, which flagged `os` and `stat` as first-party.)
Verified: the bundler's copy replicated exactly into a temp dir and booted with
PYTHONPATH=<bundle>:<bundle>/lib -- `import server`, `import appstate`,
`import routers.audio_effects` all resolve, appstate.meta_db is server.meta_db,
143 routes. The same simulation against origin/main reproduces the production
ModuleNotFoundError. pytest 2398 passed (2348 + 50 new); route table still
identical to origin/main (paths, methods, order); docker build context reaches
lib/appstate.py and lib/routers/ with no __pycache__; native uvicorn boot smoke
serves /api/version, /api/library, the moved audio-effects router, and all three
migrated plugins' src/ graphs; eslint 0 errors.

The first route module through the appstate seam (#833). Picked BY MEASUREMENT,
not by the plan's guess: a transitive dep-closure scan over every route group
ranked audio-effects at 0 monkeypatch.setattr targets and exactly one exclusive
helper. (The same scan disproved the plan's assumption that artists/aliases was
free -- api_artist_links reaches _mb_http_get and _enrich_network_enabled, both
setattr targets.)
Bodies are verbatim. The only edits are mechanical:
@app.get(...) -> @router.get(...)
audio_effect_mappings.x -> appstate.audio_effect_mappings.x
The singleton read must stay a module attribute resolved at call time, so a
re-imported server re-publishes a fresh DB into the seam and monkeypatch reaches
this module. `routers/` never imports `server`: server -> routers -> appstate.
`app.include_router(...)` sits exactly where the routes used to be defined --
FastAPI matches in registration order, so the mount site preserves it. Verified
by diffing the FULL route table against origin/main: 143 routes, identical
paths, methods AND order.
server.py: 9,445 -> 9,386 lines. `fastapi.Query` went dead with the move and was
removed (the other four unused imports are pre-existing on main).
Packaging: COPY routers/ /app/routers/ plus `!routers/` + `!routers/**` in
.dockerignore (that file opens with a blanket `*`). Verified against the real
docker daemon: routers/ reaches the build context, __pycache__ does not.

* feat(server): add appstate.py, the router seam (R3)
Routes moving out of server.py need `meta_db` and friends, but must not
`import server` -- that goes circular the moment server imports them back.
server.py keeps CONSTRUCTING its singletons and now injects them once via
`appstate.configure(...)`; routers read them back as module attributes at call
time (`import appstate; appstate.meta_db`). The Python analogue of the frontend
refactor's `configureX({...})` seams and of the plugin `setup(app, context)`
contract: dependencies flow one way, server -> routers -> appstate.
Two properties are load-bearing, both pinned by tests/test_appstate.py:
1. `import appstate` constructs nothing and touches no disk. This is why the
~49 test fixtures that `sys.modules.pop("server")` + re-import (to rebuild
meta_db under a patched CONFIG_DIR) keep working UNTOUCHED. A singleton
owned by appstate would survive that pop and go stale -- verified.
2. Reads must be late-bound. `from appstate import meta_db` freezes the binding
and defeats both a later configure() and monkeypatch.setattr -- the same
read-only-binding trap as ES imports.
configure() raises on an unknown slot instead of silently creating a global
nothing reads, and the suite asserts server ACTUALLY calls it. Negative-checked:
dropping the configure() call fails exactly the two wiring tests while the other
five stay green -- those five are the false-green a seam test must not be.
The new suite imports server through an `isolated_server` fixture that patches
CONFIG_DIR to tmp_path and closes both DB connections on teardown. An unguarded
`import server` constructs MetadataDB + AudioEffectsMappingDB under the real
`~/.local/share/feedback` (reproduced: running the file alone created
web_library.db + audio_effects.db there). The full suite now leaves the real
config dir untouched.
Packaging: `COPY appstate.py /app/` plus a .dockerignore allowlist entry. That
file opens with a blanket `*` exclusion, so root-level Python must be re-allowed
explicitly -- without it the image build fails on the COPY. Verified against the
real docker daemon (build context reaches /app/appstate.py). docker-compose.yml
gains the dev bind-mount; docker-compose.nas.yml runs the baked image, so the
COPY covers it. `routers/` will need the same two entries when it lands.
Verified: pyflakes clean; pytest 2348 passed (2341 + 7 new); eslint 0 errors;
boot smoke serves /api/version, /api/library, /api/audio-effects/mappings, and
all three migrated plugins' src/ graphs, with `appstate.meta_db is server.meta_db`
asserted against the live import.

* test(appstate): address CodeRabbit — restore slots on teardown, really re-import
Two real findings on #833, both fixed:
(1) `isolated_server` closed server's DB connections but left `appstate.meta_db`
and `appstate.audio_effect_mappings` published and pointing at the closed
handles -- a live-looking, dead singleton for any later test. Teardown now
snapshots and restores both slots.
(2) `test_reimporting_server_republishes_the_fresh_singletons` never performed a
second import: it only re-asserted what `test_server_wires_the_seam` already
covers, so it could not detect the very staleness it names. (I introduced
that regression while fixing Codex's CONFIG_DIR isolation finding.) It now
pops `server`, re-imports under a SECOND CONFIG_DIR, and asserts the seam
republishes -- `second_server.meta_db is not first_db` and
`appstate.meta_db is second_server.meta_db`.
Negative-checked both directions: simulating an appstate-OWNED singleton
(configure() only-first-wins) now fails the re-import test, and dropping
server's configure() call still fails exactly the two wiring tests.
NB CodeRabbit's committable suggestion inserted the snapshot above the
fixture docstring, which would have demoted it from __doc__; written by hand
instead.
pytest 2348 passed; the full suite leaves the real ~/.local/share/feedback
untouched.

Move-only, same shape as the MetadataDB extraction. The core-owned song/tone ->
audio-effect-provider routing index leaves server.py for a flat lib/ module.
The class body is byte-identical; server.py reconstructs exactly from
origin/main minus the cut range plus the import-back and the call site.
server.py: 9,705 -> 9,433 lines.
The only non-verbatim change is the constructor seam: `__init__` takes
`config_dir` instead of reading the module-level CONFIG_DIR, so the module does
no IO at import (Principle V). The `audio_effect_mappings` singleton stays in
server.py -- no route, no test, and none of the `monkeypatch.setattr(server, ...)`
targets move. No import went dead.
Verified: pyflakes clean on the new module; no new undefined name in server.py;
pytest 2341 passed; eslint 0 errors; boot smoke drives the extracted DB
end-to-end (POST a mapping -> GET reads it back -> audio_effects.db lands in
CONFIG_DIR, proving the config_dir seam) and all three migrated plugins still
serve their src/ module graphs.

Move-only. The library metadata cache -- the `MetadataDB` class (4,018 lines)
plus the query helpers it owns (keyset paging cursors, the tuning grouping key,
smart-arrangement naming, tag normalisation, the startup DB-restore swap) --
moves out of server.py into a flat `lib/` module. Every moved block is
byte-identical to its server.py original; server.py is exactly origin/main
minus the six cut ranges, minus the now-dead `import contextlib`, plus the
import-back block and the constructor call site.
server.py: 14,037 -> 9,705 lines.
The one non-verbatim change is the seam that lets the class leave server.py:
`MetadataDB.__init__` now takes `config_dir` explicitly instead of reading the
module-level CONFIG_DIR, so `lib/metadata_db.py` does no IO at import
(Principle V). The `meta_db` singleton stays in server.py, so `server.meta_db`
(282 refs) and `server.app` (67 refs) resolve unchanged and no route moves.
None of the 114 `monkeypatch.setattr(server, ...)` targets moved.
Logging still goes through the `feedBack.server` logger, so log filters and
caplog assertions resolve to the same logger object.
`tests/test_settings_export_library_db.py` imports `_apply_pending_db_restore`
from metadata_db (the test moves with its subject); no other test changed.
Verified: pyflakes clean on the new module (zero undefined names, zero unused
imports) and no new undefined name in server.py; pytest 2341 passed;
node --test 1030 passed; eslint 0 errors; uvicorn boot smoke serves
/api/version, /api/library, and all three migrated plugins' src/ module graphs
(stems, studio, editor -> 200).

* 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.

* 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.

* fix(library): chunk user_meta_map + rebuild stale tailwind css
Address review-bot findings on the difficulty sort/badge:
- user_meta_map now chunks filenames into 400-row batches (like
overrides_map) before the IN (...) query. query_artists (tree view)
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.

* 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).

* feat(v3): add a handedness (left-handed) choice to the instrument selector + onboarding
Left-handed players could already mirror the highway, but only via a buried
Settings toggle they had to find AFTER setup -- so a lefty went through the tour,
the tuner and calibration all right-handed first (community callout).
Add a "Handedness: Right / Left" row to the v3 instrument badge popover, alongside
Instrument / Strings / Tuning (all player-orientation choices). It writes the same
lefty preference -- highway.setLefty when a live highway exists (flips it
immediately + persists), else the 'lefty' localStorage key the highway reads on
init -- and keeps the Settings "Left-handed" checkbox in sync. The first-run
tour's "Choose your instrument" step, which runs before the tuner/audio-
calibration steps, now calls it out so lefties flip it up front.
Frontend-only, additive. Full core JS suite green (938). Tests:

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.

* 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.

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.

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.

Crossing-arrows toggle next to Play all / Play album on the playlist
detail page. When on, playQueue.start Fisher-Yates-shuffles the queue
once at start — on a copy, so the stored playlist order is untouched —
swapping per-slot album arrangements in lockstep so each slot keeps its
pinned arrangement (#685 contract preserved). Prev-less queue semantics
are unchanged: auto-advance simply walks the shuffled order.
Preference is global, persisted as localStorage v3PlaylistShuffle.

write_song_metadata dispatched zip-form packages on `suffix == ".sloppak"`
only, while core reads both suffixes everywhere else (sloppak.SONG_EXTS,
.feedpak being the current write extension). Editing a zip-form .feedpak's
title/artist/album/year therefore silently fell back to a DB-only update,
which looked fine until the next full library rescan re-derived metadata
from the file and reverted the edit — the exact failure this module exists
to prevent. Directory-form packages were unaffected (manifest-presence
dispatch, not suffix).
Gate on SONG_EXTS, add TestWriteSongMetadata regression coverage (both zip
suffixes, mixed-case suffix, directory form, unknown-suffix fallback), and
correct the stale scan_worker comment claiming .sloppak-suffix-only
detection (the code already accepts both via is_sloppak).

The guitar/bass highway_3d renderer self-detects panel-canvas size changes
in its draw() loop and re-runs applySize() every frame, because the
splitscreen host overrides hw.resize and never calls renderer.resize().
The drum and keys highways lacked that fallback — they only re-framed when
the host explicitly called resize(w, h) — so their panels stayed framed for
the pre-fullscreen size while the guitar/bass panels adapted. Symptom: a
too-small, off-center highway in the drum/keys panels after maximizing a
split-screen session.
Port highway_3d's per-frame drift check into both draw() loops: re-apply on
backing-store change (canvas.width/height) AND on CSS-box drift
(clientWidth/clientHeight vs the last applied logical size, throttled to
every 10th frame). Track _lastHwW/_lastHwH + _appliedW/_appliedH per
instance and reset them in destroy() so a reused instance re-frames on the
next song.
plugins/drum_highway_3d -> 0.3.1, plugins/keys_highway_3d -> 0.1.1.
Tests: tests/js/drum_keys_highway_3d_resize_reframe.test.js.

* Fix v3 Songs A–Z rail: reliable taps, precise drag, hittable size
Follow-up to #634. Three rail bugs reported on macOS + Windows (0.3.0,
2026-06-29 — =Scr4tch=, MajorMokoto):
- Taps often did nothing ("clicked O, nothing happened"). pointerdown
calls setPointerCapture, after which the browser retargets the
follow-up click to the rail container, so the click handler's
closest('.v3-azrail-letter') resolved null and a plain tap (no
pointermove) had no other path. Drive the jump from pointerdown
itself; reduce the click handler to keyboard activation only
(e.detail === 0, Enter/Space).
- A drag landed short of the release ("where you release isn't where
you get sent"). Every letter crossed fired jumpToLetter with
behavior:'smooth'; stacked smooth-scroll animations over the
virtualized grid lagged and settled imprecisely. jumpToLetter now
takes a smooth flag and scrolls instantly ('auto') while scrubbing,
animating only discrete taps/keyboard jumps, so the grid tracks the
finger and the release lands on the let-go letter.
- The rail was too small at 1440p and didn't scale. Letters were a
fixed .62rem glued at right:2px (~13px-tall target). They now scale
with the viewport (clamp(.72rem, 1.4vh, 1.05rem)), sit off the edge
with taller/wider equal-width hit targets and a hover/active
highlight so the scrub target is visible.
Keyboard arrow-nav and present-letter gating are unchanged. Tests:
tests/js/v3_az_rail.test.js gains pointerdown-seek, keyboard-only click
guard, and instant-vs-smooth assertions (809 JS tests; the 13
pre-existing unrelated failures are unchanged).

* fix(v3): ignore non-primary buttons on A–Z rail pointerdown (PR #653 review)
Right- or middle-clicking the A–Z rail (or a secondary multi-touch
pointer) no longer triggers a seek; only the primary tap/drag scrubs.

Favoriting from the tree / "List View" flipped the glyph ♡→♥ but the
heart stayed grey until a re-search — reported macOS+Windows, open since
0.3.0 / 2026-06-25.
One shared wireCards() [data-fav] handler serves both the grid card and
the List-View row, but they render with different idle colours (grid
text-white, List View text-fb-textDim) and the handler only ever removed
the grid's text-white. So in List View text-fb-textDim lingered next to
the freshly-added text-fb-accent and won by CSS source order — the glyph
changed but the colour didn't, until a re-search re-rendered the row.
Each heart now declares its idle colour via a data-fav-idle attribute;
the handler swaps exactly that class (so only one colour class is ever
present) and writes the new state back onto the in-memory song model so a
re-render / virtualized-grid recycle agrees instead of reverting.
Tests: tests/js/v3_favorites_toggle.test.js. Full JS suite 810 tests; the
13 pre-existing unrelated failures are unchanged.

First slice of the host theme contract (#644): give plugins a host-owned way to
read the active theme + its device affordances, so a feature renders correctly
under any theme instead of binding to whichever one the dev saw.
theme-core.js previously only APPLIED themes and emitted --fbv-* vars only while
a theme was equipped (nothing to read in the default state), with no read API.
Now, all additive + feature-detected:
- Always-present default `fb` palette as `--fbv-*` on :root (the un-themed look
is unchanged — fb-* utilities still use their compiled defaults; this only
hands plugins a stable host token to read + derive surfaces from). Adds two
keystone ROLES the palette lacked: `on-accent` (legible fg on the accent fill)
and `focus-ring`.
- window.feedBack.theme.get() -> {id, isThemed, tokens}; .capabilities() ->
{glow, gradients, motion} (the device-affordance signal; recolor-only themes
report defaults, a theme may opt out via `capabilities` in its payload, motion
is reduced-motion-gated); .prefersReducedMotion().
- Normalized `theme:changed` event from the single apply() chokepoint.
The apply side stays on window.v3Theme; the read surface is attached defensively
so it survives the feedBack bus being (re)built by capabilities.js regardless of
load order. Verified via a headless render (apply/unequip intact, defaults
present + restored, capability opt-out honored, event payload correct) +
tests/js/v3_theme_read_api.test.js. See docs/host-theme-contract.md.

Removes the Floating Button and Tuning Visibility settings sections and finishes retiring their still-live config: drops the disabledTunings menu filter and showFloatingButton gate from screen.js/ui.js and their persistence in routes.py (retired keys are stripped on write). Repositions the tuner panel opened from the v3 sidebar Plugins popover to anchor beside it via the host's stable plugin-control slot API (falling back to the popover id), clamped to the viewport so it can't open off-screen, and re-anchored on resize. Updates tuner config tests to the retired-key behavior; plugins/tuner 1.3.2 -> 1.3.3.

* fix: correctly import and notate multi-staff (piano/keys) tracks from GP8

* fix(gp-import): fold all grand-staff staves, per-stave tuning, playable hand-splits
Addresses review on #692 (topkoa):
- split_hands: only use the middle-C boundary when both resulting hands are
within HAND_SPLIT_SPAN_SEMITONES, else fall back to the largest-gap
heuristic — a hard middle-C split otherwise put a 19-semitone (unplayable)
span in one hand for bass-under-treble voicings (e.g. E2+B3 under an Em7
shape).
- Treat any multi-stave (grand-staff) track as keys end-to-end, so the
stave-0 and folded stave-1+ notes share one encoding and note_count (which
sums every stave column) matches what actually imports — closing the
phantom-count case for grand-staff instruments the name/program heuristics
miss (harp, celesta, marimba).
- Fold *every* extra stave (stave_columns[1:]), not just stave 1.
- Per-staff tuning fall-back to the track-level Tuning property so an untuned
staff never yields an empty pitch list (silent note loss); via a shared
_parse_tuning helper.
- Extract _collect_column_notes / _merge_lh_notes so the GPX LH/RH pair merge
and the GP8 grand-staff fold share one implementation and can't drift in
tie/timing/dedup handling.
- Rebuild filtered_to_raw from the already-computed stave_columns (one source
of truth for the counting rule) and drop the dead num_raw_tracks/raw_tracks.
Tests: grand-staff fold + bar-column offset (test_gp2notation.py); both
middle-C split cases (test_notation_lift.py). CHANGELOG updated.
