f7b065d236 fix(plugins): restore window.esc for out-of-tree plugins
app.js exported `esc` as an implicit global back when it was a classic
script. a9fce29 made it an ES module and 14b4058 carved `esc` into
js/dom.js; the window re-export list was rebuilt without it.

Out-of-tree plugins load screen.js as a classic script and call `esc()`
bare, so nothing in-tree catches the break: no-undef, a call-graph scan
and a grep all pass while the plugin throws in the field. The MIDI
plugin builds its device list with esc() inside the same try block that
catches requestMIDIAccess() failures, so the ReferenceError surfaced to
testers as "MIDI Access denied esc is not defined" — access had actually
been granted.

Pin the whole plugin-facing global surface by name, mirroring
tests/test_plugin_context_contract.py. Verified both ways against a
running app: without the fix the spec fails with "missing or not
functions: esc".

perf(scan): skip full library re-stat when the tree is unchanged (#979)
Some checks are pending
ship-ci / ci (push) Waiting to run
* perf(scan): skip full library re-stat when the tree is unchanged

Startup scans globbed the whole DLC tree twice (*.feedpak, *.wem) and
stat()'d every file to detect changes — ~100k filesystem round trips on
a 50k-song library, and painful on a slow NTFS-3G FUSE mount (the "big
drive churns on every launch" report).

Adds/removes/renames of songs all bump the mtime of the containing
directory (verified on the target mount), so after a full pass we persist
{reldir: mtime_ns} for every library dir (scan_dir_signature.json, keyed
by DLC path). The next scan re-stats only those dirs — a handful vs 100k
ops — and skips the entire listing/stat pass when none changed.

Blind spot: a pack rewritten in place under the same name bumps the file
mtime but not its dir's. Rare for a song library, and the manual Refresh
(/api/rescan + /api/rescan/full) now passes force=True to always do the
full pass. force threads through kick_scan -> _scan_runner and coalesces
like the rescan-pending flag.

* fix(scan): track directory-form songs' own dir in the signature

CodeRabbit: _library_dirs recorded only each song's parent. For a
directory-form song (loose-song folder or directory sloppak bundle),
adding/removing/replacing a file INSIDE the folder bumps that folder's
own mtime, not its parent's — so the fast path would skip a rescan it
should run. Record the song's own dir when f.is_dir(). File-form
sloppaks (a single .feedpak zip) aren't dirs, so the flat file library
is unaffected.

fix(venue): fly in once per set, not before every song (#978)
Some checks are pending
ship-ci / ci (push) Waiting to run
Tester, mid-gig: "the second song in the gig started when the first one ended.
But it showed the flyover intro again."

The flyover is arriving at the venue, and you arrive once. #968 stopped it
replaying on an arrangement SWITCH (same filename), but a gig's song 2 is a
genuinely different file, so it took the full-teardown path and played the
arrival flyover again — the camera flew in from the back of the room before
every track of the set.

The play queue now answers isContinuation(): false for the first song of a set
(or a standalone play — an arrival), true for song 2..N. onSongLoaded carries
the room over to the new song's loop on a continuation, and only a real arrival
plays the intro.

Verified on the built AppImage: isContinuation goes false (song 1) -> true
(song 2) across an advance, and song 2 no longer flies in.

Also confirmed NOT a bug, same session: "didn't show the author for the second
song." The credits card shows on a queue advance whenever the song carries
authors — reproduced with a song that has them as the advanced-to track. The
tester's song 2 simply had no `authors:` metadata (most auto-converted feedpaks
don't). No code change.

Tests: isContinuation across start/advance/clear, and that onSongLoaded gates the
flyover on the continuation check. Both fail on pre-fix source. JS 1214/1214.

fix(playback): the song queue must survive a playSong wrapper that drops options (#977)
Some checks are pending
ship-ci / ci (push) Waiting to run
Tester: "Passports does not advance in the song queue."

The play queue tells playSong "don't clear the queue I'm driving" by passing
options.fromQueue. But window.playSong is wrapped by a CHAIN of plugins —
nam_tone, midi_amp, fretboard, invert_highway, tabview — and each wrapper
forwards only (filename, arrangement), silently dropping the options object. So
fromQueue never reached playSong: it cleared the queue the instant its first
song started, and a gig/album/playlist never advanced.

Reproduced on the real build via a queue.start + a hooked clear(): the queue
went inactive with 0 remaining immediately after start, and the clear stack ran
through nam_tone -> midi_amp -> invert_highway -> fretboard -> session.js.

Fixing six plugin wrappers is whack-a-mole and the next plugin re-breaks it.
Fix it at the source instead: the queue raises an out-of-band flag
(_consumeInternalPlay, one-shot) beside the wrapper chain, not through it, and
playSong's clear-guard honours it. options.fromQueue stays as the in-band path.
The flag is consumed on read so a later MANUAL play still abandons the queue.

Verified on the real build: the gig queue stays active after start and advances
on song:ended (Iron Maiden -> Blind Guardian), and a manual play still clears.

Tests drive the real clear-guard against the queue for: a dropped-options
wrapper (the bug), the one-shot manual-play-still-clears invariant, and the
in-band fromQueue path on its own. All 3 fail on the pre-fix source. JS 1211/1211.

fix(career): gig song selection — full-genre pool, working re-roll, and the venue pack loads (#976)
* fix(career): a gig's song pool is the whole genre, and re-roll varies it

Two tester reports, one root: the gig song pool was built from only two sets —
songs played ON THIS PASSPORT'S INSTRUMENT, and songs never played AT ALL
(`filename NOT IN song_stats`).

A song played on a DIFFERENT instrument's arrangement is in neither: it has a
stats row (so the "unplayed" filler skipped it), and its played bucket is that
other instrument's, not this passport's. It could never be gigged.

- "Metalcore says 137 songs only shows 1 in the gig list" — a library of
  metalcore all played on another instrument. Reproduced: a guitar passport with
  137 bass-played metalcore songs got a 404, zero songs. The "1" the tester saw
  was whatever handful happened to be on-instrument or truly unplayed.

- "Passport re-roll does not change songs" — a set drawn from that filler was the
  library's first N in table ORDER, every call. Re-roll re-proposes, so it
  returned the identical set. Reproduced: 3 proposals, byte-identical.

_unplayed_genre_songs -> _fill_genre_songs: the pool is now every library song of
the genre the set hasn't already picked (a stats row on some other instrument has
no bearing on whether a song can be in THIS gig), and it is shuffled so re-roll
actually re-rolls.

Both reproduced against the real propose logic before the fix and pinned as
regression tests (both fail on the pre-fix routes.py). Full career suite green.

* fix(career): load the gig's venue pack when the gig starts

Tester: "Venue doesn't load when starting song from passport. Loads standard
particles."

crowd.setManifest(venue) — the call that actually loads a venue's crowd/stage
pack — is reached ONLY through pushCrowdManifest, and pushCrowdManifest is
called ONLY from refresh(), the career tab's own reload. A gig navigates AWAY
from the career tab to the player, so refresh() never runs during it. startGig
set the venue override and nulled _appliedManifestVenue but never re-pushed, so
the venue visualization turned on (3D highway) while its pack never loaded — the
song played over the bare highway backdrop, or over whatever venue a previous
refresh() had left applied.

startGig now pushes the crowd manifest for the gig venue right after setting the
override, using the career state the booking screen already fetched.

This is a call-graph fact, not a guess (pushCrowdManifest has exactly one other
caller and startGig is not it), but it is fixed by static analysis — I could not
reproduce the user-visible symptom locally because this instance happened to have
a manifest already applied from a prior refresh. On-device confirmation on a real
passport gig is still owed.

Guard test: startGig must push the manifest after setting the override (fails on
the pre-fix source). Career suite green.

feat(career): extract the whole setlist before the gig starts (no more waiting between songs) (#971)
Some checks are pending
ship-ci / ci (push) Waiting to run
* feat(career): extract the whole setlist before the gig starts

A feedpak is a zip, and the first play of one pays for its extraction into
sloppak_cache. Inside a set that cost landed BETWEEN songs: the player finished
a number and then sat there waiting for the next one to unpack, mid-gig.

A setlist is a known list up front, so unpack it all while the poster is still on
screen. New POST /gigs/prepare walks the set through resolve_source_dir; the
poster's Play button shows "Preparing set…" while it runs.

Best-effort by design, at every level:
  - a corrupt pak in the set does not sink the prepare (it is reported in
    `failed`; the play itself surfaces the error exactly as it does outside a
    gig — slow beats blocked)
  - a host without the library resolvers degrades to a no-op rather than 500
  - a failed request just falls through to the old lazy extraction

Ordering matters and is pinned: the set is unpacked BEFORE the stage is borrowed
(venue/viz overwritten) and before the queue starts, so a proposal cancelled
while unpacking leaves nothing half-applied to unwind.

Tests unpack REAL zips rather than mocking the extractor: every song of the set
lands on disk before the first note, a re-prepare does not duplicate the unpack,
one bad pak still leaves the good one prepared, and no-library / empty-setlist
degrade cleanly. 18/18.

NB the other half of the gig report — the per-song results popup interrupting
the set (and worse, claimAutoExit'ing so the queue would not advance until it was
dismissed) — is fixed in the note_detect plugin repo, which is not part of this
checkout.

* fix(career): bound the prepare request; validate the setlist (PR #971 review)

Both CodeRabbit findings were right.

1. A HUNG PREPARE COULD BLOCK THE GIG FOREVER.

   `await fetch(...)` only rejects on a network ERROR. A server that accepts the
   connection and then never answers hangs indefinitely — and the gig would never
   start. That makes this optimisation the exact thing the PR promises it can
   never be: the reason you cannot play.

   The request is now bounded by an AbortController (PREPARE_TIMEOUT_MS, generous
   because unpacking a setlist is real work — but a CEILING, not a wait). Past it
   we start the gig and let the first play extract lazily, as it always did. The
   Play button is restored in a `finally`, so a timeout cannot strand the poster
   on "Preparing set…" with Play disabled — which would have been the same bug
   wearing a different hat.

2. THE `songs` BODY WAS UNVALIDATED.

   A str is iterable: "abc" would have prepared three one-character "songs". And
   the endpoint unpacks zips, so an arbitrary caller could ask for unbounded work.
   Now list-only, string entries, blanks dropped, capped at MAX_GIG_SONGS.

Tests: the fetch is abortable and the button is re-enabled on EVERY path
including the abort; non-list bodies, non-string/blank entries, and an
oversized setlist. 50 career tests, JS 5/5, eslint clean.

* fix(career): path-traversal guard on prepare; a cap test that actually tests the cap

CodeRabbit again, and the first one is a real hole I put there.

1. PATH TRAVERSAL. sloppak.resolve_source_dir() does a bare `dlc_root / filename`
   with NO containment guard — so `../../x` walks straight out of the library, and
   my new endpoint handed it attacker-supplied filenames. Every filename now goes
   through _resolve_dlc_path first, the same check every other filename-bound
   handler applies. Pinned: `..`, backslash traversal, an absolute POSIX path and
   a Windows drive path are all refused, and nothing outside the library is
   unpacked.

2. THE CAP TEST WAS VACUOUS. It asserted `prepared == 0` against a fixture with no
   library — where the endpoint exits before extraction — so it passed whether or
   not MAX_GIG_SONGS existed. It now runs against a real library and asserts the
   endpoint CONSIDERED at most MAX_GIG_SONGS of the 82 it was handed. Verified to
   fail when the cap is removed.

   Same class of mistake as the notedetect gigBlock: a test that passes for the
   wrong reason. Worth saying out loud since it is twice in one day.

3. E702 — semicolon-joined statements in the new tests, split.

51 career tests; full suite green.

fix(highway): a SUPERSEDED renderer init is not a FAILED one (#970)
Starting a gig dropped the player onto the fallback 2D highway with no venue.

startGig() calls setViz('venue'), which installs the 3D renderer — whose init is
async — and then immediately starts its play queue. playSong() re-initialises
that same renderer a tick later. A renderer mints a fresh readyPromise per
init() and rejects the previous one with "superseded"; highway.js only checked
that the RENDERER OBJECT was unchanged, which it is. So it treated a healthy,
re-initialising renderer as a failed one, tore it down, and reverted to 2D:

    renderer async init failure: Error: superseded
    viz picker: reverted to default renderer (async-init-failure)

The guard now also checks the PROMISE identity: a rejection from an init cycle
the renderer has already moved on from is ignored. The renderer-identity guard
stays (a rejection for a renderer since REPLACED is also not ours), and a
genuine failure of the CURRENT cycle still reverts — both init() call sites go
through _setRenderer, which re-wires the handler every time, so the new cycle is
always watched.

Reproduced and fixed against the real build:

    before:  vizSelection=default  viz-picker=default  venue=inactive  viz:reverted
    after:   vizSelection=venue    viz-picker=venue    venue=ACTIVE    (no revert)

Also widens the paused-frame throttle's opt-out. The throttle fires whenever the
CHART CLOCK is stalled — not only on a pause, but through a count-in and the
credits/author overlay too. Its opt-out only asked "is a crowd video rolling",
but the venue scene animates on a clock of its own with no pack at all (backdrop
breathe, parallax, haze drift, warmth pulse — Math.sin(t) in the draw loop), so
that motion was still being throttled. It now claims frames for both sources; a
plain 3D highway with no venue reads motion mode 'off' and keeps the #654 GPU
saving.

HONEST CAVEAT on that second part: I could not get the throttle to fire in a
reproduction. A control run on the shipped code showed 100 draws/sec while
paused, not the ~10/sec a firing throttle would give — so the change is
defensible on its own terms (a stalled clock is genuinely not a static picture)
but it does NOT have a demonstrated symptom behind it. The viz fix above does.

Tests: the superseded guard, and that the throttle opt-out covers both motion
sources. All fail against the pre-fix source. eslint 0 errors; JS 1207/1207.

feat(song-info): publish the playable stem list so stems can preload (fixes the 698ms freeze) (#972)
* feat(song-info): publish the playable stem list, so stems can preload

The stems plugin could only learn its stem list from the highway's WS `ready`,
which arrives once the highway is already up. So it fetched, decoded, and then
handed every stem's PCM to its audio worklet — copying the WHOLE SONG — with the
player already on screen.

For a 4-minute 6-stem pack that is over half a GIGABYTE of memcpy, in one frame,
on the main thread. Measured on a real load: a 698 ms frame, right as the
song-credits card appeared, with the venue video visibly stopping. That is the
"the video pauses when the author appears" report.

GET /api/song/{f}?stems=1 now returns the same list — [{id, url, default}] plus
full_mix_url — so the plugin can start the whole load at `song:loading`, before
the highway (and the venue) is drawn, where a stalled frame costs nothing.
Nothing about the work changes; only WHEN.

Opt-in via the query param so the library's own metadata calls — the hot path —
pay nothing. Deliberately NOT stored in the metadata cache: that is a
fixed-column table, and widening it would mean a schema migration plus a stale
row for every song already scanned, to cache something that is a plain manifest
read on an already-unpacked pack.

The safety property: REST and the WS must publish the SAME list. If they
disagreed the plugin would preload a graph and then throw it away and rebuild —
strictly worse than not preloading. So both now resolve `default` through one
shared helper (stem_default_on, extracted from load_song), and a test rebuilds
the WS's payload from load_song and requires the REST helper to produce the
identical list, rather than pinning either against a snapshot.

Also pinned: the mixdown is lifted OUT of the stem list (spec 5.3 — `full` is
not a layer; listing it beside the instruments would play the whole song on top
of the stems) while staying reachable as full_mix_url, a single-`full` pack keeps
it as its only playable stem, and an unreadable pack yields an empty list rather
than failing the request. Full suite 2608 passed.

Consumed by feedBack-plugin-stems (preloadSong).

* fix(song-info): call load_song for the stem payload — do not reimplement it

CodeRabbit caught a real bug, and it would have hit most real libraries.

load_song() falls back to the DEPRECATED `original_audio:` key when a pack has no
reserved `full` stem — which is every pack written before feedpak 1.15.0. My
payload rebuilt the full-mix rule from extract_meta and returned None for those:
REST would say "no full mix" while the WS said there was one.

Worse than a wrong field: the plugin would preload a graph WITHOUT the pristine
mix and — because the stem signature still matched — never rebuild. Unity
playback would silently downgrade to the lossy stem recombination.

That is exactly the drift this PR claims to prevent, and my test had a hole: I
only covered packs that carry a `full` stem.

So stop reimplementing. The payload now calls load_song, whose LoadedSloppak
already carries the partitioned stems and the resolved full mix, and builds the
URLs exactly as ws_highway does. Drift is now impossible by construction rather
than by agreement. extract_meta is reverted to its original shape (it never
needed to change), and the shared stem_default_on helper stays as the one place
`default: off` is resolved.

Tests rewritten to compare against load_song — the WS's own function — for a
reserved-`full` pack, a LEGACY original_audio pack (the case that was broken), and
a single-`full` pack. Also documents the `?stems=1` contract in CHANGELOG.md.
Full suite green.

fix(venue/highway): flyover replay on arrangement switch, venue on Virtuoso, and the paused throttle starving the venue (#968)
* fix(venue): don't replay the flyover on an arrangement switch; keep the venue off other screens

Two bugs from a live career session.

1. CHANGING ARRANGEMENT REPLAYED THE ARRIVAL FLYOVER.

   changeArrangement() reloads the song through the normal load path, so
   highway.js re-emits `song:loaded` — same filename, new arrangement. The venue
   could not tell that from a fresh arrival, so it reset the machine and flew the
   camera in from the back of the room again, mid-set, every time the player
   switched lead -> rhythm. The player is already on stage.

   onSongLoaded now compares the filename. A repeat of the song already on stage
   keeps the video pipeline running and only re-syncs the mood: the performance
   restarts, so the loop follows the reset machine with a quiet crossfade, never
   the intro. A genuinely different song still gets the full teardown + flyover.

2. THE VENUE SHOWED UP ON THE VIRTUOSO HIGHWAY.

   The venue was gated purely on `isVenueViz()` — the selected visualization,
   which is a GLOBAL preference and says nothing about what is on screen.
   Virtuoso borrows the same highway_3d renderer for its practice charts, so with
   Venue selected it inherited the backdrop: the crowd and the stage behind a
   chromatic exercise.

   Selecting Venue is a preference for the PLAYER; it is not a licence to paint
   the venue over whatever else happens to be using the renderer. The venue is now
   gated on viz AND screen (`shouldBeActive`), and follows `screen:changed` — it
   tears down on leaving the player and rebuilds on return. Nothing else changes:
   stop() already unbinds the videos from the renderer, so deactivating is enough
   to clear the backdrop.

Tests: both decisions exposed as pure predicates and pinned — arrangement switch
vs new song (including the first load, and a malformed payload that must not
suppress the flyover forever), and the venue's screen scope. The existing syncViz
test encoded the OLD contract (activate regardless of screen), so it now states
the new one and additionally asserts the venue does NOT activate on virtuoso.

Includes a guard test: with Venue selected AND on the player, the venue IS
active — without it, every "not active" assertion could pass vacuously.

All 8 new/updated assertions fail against the pre-fix source. eslint clean;
JS 1199/1199; pytest 2597 passed.

* fix(highway): the paused-frame throttle was throttling the whole venue

Pausing the song dropped the venue, the crowd and the stage to ~10 fps —
"everything around the highway drops fps by a lot".

draw() caps paused frames to one per _PAUSED_FRAME_INTERVAL_MS (100ms), on an
assumption stated plainly in highway-constants.js: a heavy WebGL renderer "does
a full render every frame even while paused. That is pure waste." That was true
when a paused chart was a still picture.

The venue broke the assumption. Its video backdrop keeps playing and its crowd
reacts on a clock of their own, and BOTH are drawn into the same canvas as the
notes — so a throttle aimed at static notes throttled the entire room. The
scene only got a texture upload 10 times a second while the transport sat
paused.

Renderers can now declare that their picture is not static while the chart
clock is stopped: an optional needsContinuousFrames(). The throttle is skipped
only when it returns exactly true, and the probe fails closed — a renderer that
doesn't implement it, or one that throws, keeps the throttle unchanged. So the
GPU saving that motivated #654 survives everywhere it was actually valid.

highway_3d implements it and claims continuous frames ONLY while a crowd video
is genuinely rolling (bound, unpaused, not ended, readyState >= 2). With no
venue pack — the common case — the paused scene really is static, so it keeps
the throttle and the GPU still idles.

Tests extend tests/js/highway_pause_throttle.test.js, which guards this code
path source-level (the draw loop owns the rAF + WebGL lifecycle and is
deliberately not reproduced in a vm — see the file header). The new guards pin
that the capability GATES the early return rather than merely being called near
it, that the probe fails closed on absent/non-function/throwing/truthy-but-not-
true, and that the 3D renderer keys off the real video elements and can still
return false. All 3 fail against the pre-fix source.

perf(paths): resolve the library root once, not on every path check (#966)
`Path.resolve()` is a filesystem call — it lstats every component of the path.
`_resolve_dlc_path` and `safe_join` both re-resolved their ROOT on every single
call, and those run once per song, per art fetch, per scanned row.

Found while profiling a 2-fps report: on a real 50,944-song library the server
was issuing ~23,500 stat/lstat calls per second, re-walking the same three
parent directories over and over, and burning ~50% of a core doing it. It is
worst exactly where big libraries live — the library was on an NTFS-3G (FUSE)
mount, where every stat is a userspace round trip through mount.ntfs-3g (itself
visible in top). The cost was the constant re-resolution, not the work.

A root is fixed for the life of the process, so resolve it once
(safepath.resolved_root, lru_cache). Measured, 5,000 lookups against a real
library path:

    before:  15,264 stat syscalls   (54.2 ms)
    after:       277 stat syscalls   ( 0.8 ms)     55x fewer

Containment is unchanged, which is the part that matters:
  - safe_join still resolves the CANDIDATE on every call — following its
    symlinks IS the zip-slip / traversal defence, so it is never cached. Only
    the server-owned root is.
  - _resolve_dlc_path keeps its lexical containment check (deliberately does not
    follow symlinks, so junction-mounted libraries keep working).

Tradeoff, documented on resolved_root: if a root's symlink is re-pointed at a
NEW target while the server runs, the old target stays in effect until restart.
Fine for a library path fixed at startup; the cache is keyed on the Path, so
switching library dir is a different key.

Tests: root resolved once across 500 lookups (the regression), a different root
is a different entry, and the containment contract re-pinned — traversal,
Windows drive-absolute, backslash, NUL, empty, and a symlink escaping the root
must still be refused. Full suite green.

gained-only merged like drill nodes) turns an earned badge gold when the
passport's genre — or its genre family — has a verified improv artifact.
Gold never substitutes for the badge bar: gold-without-bronze stays
in_progress.

* feat(career): Gold tier frontend — relay, ceremony, slam, gold ink everywhere

The drill-state relay now carries virtuoso's goldImprov map; a badge that
comes back gold gets its own ceremony + notification (tier-suffixed seen
ids — the bronze moment stays seen under its legacy id, a gold slam marks
both), a gold stamp slam in the book, gold ink on the shelf-cover mini
stamp, and the real gold foil chip. The bronze page's dashed 'Gold rung
coming' preview becomes a live invitation to jam the style in Virtuoso.

* fix(career): gold review fixes — family-space style matching, intake guards, rail counter

The review's showstopper: virtuoso mints goldImprov under raw
STYLE_PALETTES ids ('punk', 'djent', 'disco'), which are mostly NOT
family keys — the tier check now matches in family space (artifact style
and passport genre bucket through the same _genre_family keyword match),
so a 'punk' gold reaches a 'punk rock' passport. Also: non-dict
goldImprov 400s loudly instead of silently dropping; evidence-free
artifacts (no verifier) never mint; goldImprov gets the same pre-merge
size bound byNode has (junk under the cap could otherwise persist
forever and wedge every later relay at the post-merge check); the
instrument-rail badge counter counts gold (earning gold no longer made a
badge vanish from the rail); first-artifact-wins is now asserted against
the persisted snapshot instead of vacuously.

fix: remote transcription posts to /transcribe, not /align (stem-splitter#17) (#959)
Some checks are pending
ship-ci / ci (push) Waiting to run
* fix: remote transcription posts to /transcribe, not /align (stem-splitter#17)

transcribe_vocals_remote() POSTed the vocal stem to /align. That endpoint is FORCED ALIGNMENT —
"here are the lyrics, tell me when each word is sung" — and its `text` field is required. We have
no lyrics; transcribing them is the entire point. So the server rejected every request with a 422
from FastAPI's validation layer, before its handler ever ran, and remote transcription has never
worked for anyone.

It now posts to /transcribe (added in feedBack-demucs-server#14), which takes only the audio.

`language` moves from the query string to the FORM BODY, where the server actually reads it
(Form("")). As a query param it was silently ignored, so an explicit hint did nothing and
Whisper's auto-detection quietly decided instead — loading the wrong wav2vec2 aligner. It
"worked", it was just wrong, which is the failure mode that hides for months.

Error bodies are no longer cut at 300 chars. The body IS the diagnosis: a 422's JSON names the
field it rejected, a 500's traceback answers on its LAST line. Both got decapitated — which is
part of why this stayed invisible for so long. The message explaining the bug was inside the part
that got cut.

Nothing caught any of this because every test of this module tested the MAPPER, fed a hand-written
dict. The mapper was always fine. The request was never exercised, and the request was the bug.
tests/test_lyrics_transcribe_remote.py now pins it: the endpoint, the form field, the multipart
upload, the bearer token, an instrumental returning no lyrics rather than an error, and a 404
saying the server is too old. Verified they FAIL against /align + params.

* fix: make the error-body cap an actual bound; correct the docstring's endpoint

- _err_body() appended the truncation marker AFTER slicing to _MAX_ERR_BODY, so the result could
  exceed the cap it exists to enforce (4014 chars for a 4000 bound). A cap that is only a
  suggestion surprises exactly the callers who trust it — a log line, a job record persisted to
  disk and re-read on every load. The marker now fits inside the bound.

  It also stripped after measuring, so a short JSON body followed by kilobytes of trailing
  whitespace got truncated: real content cut to make room for blanks. Strip first, then measure.

- The public docstring still advertised /align — the exact contract this PR exists to change, in
  the one place a reader would look for it. It now says what the function does and why, and that
  an older server answers 404.

Signed-off-by: topkoa <topkoa@gmail.com>

* fix: keep the exception line when truncating — the tail is the answer

_err_body() kept only the HEAD of an over-long body. On a traceback the last line is the
diagnosis, and the docstring said exactly that while the code threw it away: a 4000-char window
holding "Traceback (most recent call last)" and none of the exception is a window onto nothing.
Same mistake as the 300-char cap it replaced, one level up — cutting off precisely the part the
function exists to preserve.

Head AND tail now, both inside the bound: two thirds head (what was being attempted), one third
tail (what actually went wrong), with the marker between them. Verified the test FAILS against
head-only truncation.

Found by Copilot on #959.

Signed-off-by: topkoa <topkoa@gmail.com>

* fix: every failure out of transcribe_vocals_remote() is a RuntimeError; 404 says why

The docstring promised one failure mode — RuntimeError — and the caller (_maybe_transcribe_lyrics)
catches exactly that so one song's failed lyrics don't take down the batch around it. But a DNS
failure, a timeout, a reset connection or an unreadable stem escaped as requests.RequestException
or OSError, walked straight past that handler, and turned "this song's lyrics failed" into "the
whole batch died".

A 404 now explains itself. Bare "404" sends someone hunting for a typo in their server URL; the
real answer is that their server predates /transcribe, and we are the only ones in a position to
know that.

feat(career): gigs backend — propose a setlist, log the completed set (#954)
* feat(career): gigs backend — propose a setlist, log the completed set

Career v3, WS3 (backend half). A gig is career's verb:

- POST /gigs/propose {instrument, genre, size}: setlist from the
  passport's own stubs — qualifying songs (per the genre's badge bar,
  family-aware) shuffled for a free re-roll, topped with the
  highest-accuracy near-bar songs as stakes, and filled from UNPLAYED
  genre songs when the passport is young (the first gig is how stubs
  start). Names the highest venue the current stars can book.
- POST /gigs: logs a COMPLETED set only (abandoned sets never log — no
  fail state). Per-song accuracy = MAX(last_accuracy) from song_stats,
  freshly written by the set's own plays; encore = avg ≥ the data-driven
  bar (passports.json gig.encore_accuracy, 0.75). Appends to the career
  state file (same atomic _save_json pattern).
- Passports view: per-passport gigs (newest first, capped 20) and
  per-instrument gig_count — the profile wall's gig line lights up.

* feat(career): practice invitations — closest stamps + bring-these-up

Career v3, WS1. The passport now points at the practice that pays:

- Stubs carry next_star_at (the same primitive _stars() uses) and each
  passport exposes `nearest`: the top 3 non-qualifying songs by distance
  to their next star, in the worklist order.
- "Closest stamps" strip above the shelf: the in-progress graded
  passports nearest to minting, each row naming the ask — N more songs
  (with the nearest title + best %) or the blocking Virtuoso drill.
  Rows open the passport.
- "Bring these up" list on the stubs page of in-progress passports;
  earned pages stay memorabilia (no homework on a won badge).
- Invitation-voiced throughout: no meters, no completion pressure.

feat(career): genre families — sub-genres inherit the family drill (#951)
The enrichment fallback made the passport rack real (hundreds of MB
sub-genres) but only the five exact umbrella keys carried Virtuoso
drills. Genres now resolve to a family by keyword substring (MB's
vocabulary is open — 'metalcore' must hit metal without an alias),
first-match-wins in list order ('blues rock' → blues), and inherit the
family's requirement from the same genres map. Exact entries still win;
per-instrument scoping unchanged; unmatched genres stay songs-only.

Data: families for metal (incl. djent/grindcore/thrash/doom), blues,
jazz (bebop/swing/bossa), funk (disco), rock (punk/grunge/shoegaze).

fix(sloppak): the full mix is a stem — drop the invented original_audio key (#946)
Some checks failed
ship-ci / ci (push) Waiting to run
Nightly / build-docker (push) Has been cancelled
* fix(sloppak): the full mix is a stem — drop the invented `original_audio` key (#933)

Core read, served, and depended on `original_audio:` — a top-level manifest key
this repo invented in #583 that the feedpak spec never defined. The format
already had a home for the pre-separation mixdown: it is a stem. feedpak 1.15.0
(feedpak-spec#53) RESERVES the id `full` for it, so read it from there.

The key existed to work around a bug in our own reader. The packer's comment
said so plainly: "we must NOT list the full mix as a playable stem — the player
sums every entry in `stems` and does not gate playback on `default`, so a listed
full mix plays on top of the stems". Faced with a reader that would double the
song, the packer put the mixdown outside `stems` and invented a key to point at
it. The fix belongs in the reader, and that is what this is.

load_song() now partitions the stem list: `full` comes out as
LoadedSloppak.full_mix, the instruments stay in .stems. Nothing that sums stems
or draws one fader per stem can see the mixdown, so retaining it is safe — which
is what lets the packer put it where the format says it goes.

- ws_highway: `song_info` gains full_mix_url / has_full_mix. The old
  original_audio_url / has_original_audio remain as deprecated aliases for one
  release so an older stems plugin keeps working (#945).
- `stems` on the wire, and stem_ids / stem_count in the library index, are now
  INSTRUMENT stems only — a separated pack that retains its mixdown no longer
  advertises a bogus "full" chip or an inflated stem count.
- enrichment: fingerprint against the mixdown wherever it lives. This widens
  coverage — _song_audio_file() previously returned None for any pack without
  the invented key, so fingerprinting silently did nothing for nearly every pack.
- sloppak: `original_audio:` is still READ as a deprecated fallback, because
  every pack in the wild carries it and would otherwise lose its pristine mix.
  tools/migrate_full_mix_stem.py rewrites those packs into the spec shape
  (original/full.ogg -> stems/full.ogg, add the `full` stem at default:off, drop
  the key); the fallback and the aliases die with #945.

The spec gate keeps the debt honest: the grandfather entry now tracks #945, and
the gate fails if it goes stale.

Verified: spec gate OK (4/4, incl. ingesting the spec's new example pack that
retains `full`); 2493 python tests, 995 js tests; migrator round-tripped over
real packs from the library and the results pass the spec's reference validator.

* fix(migrate): discover directory-form packs instead of silently skipping them

iter_packs() searched only files, so a directory-form pack (`song.sloppak/`, the
authoring shape) was walked INTO and never yielded — silently missed by a run
that's meant to be exhaustive. Discover suffix-named directories too (yielded
whole, not descended into), and route packs through migrate_pack/verify_pack.

Directory packs are REPORTED as `dir-form-unsupported`, not rewritten in place:
a single-file pack is replaced atomically (a fully-built temp archive swapped in
with one os.replace), but a populated directory can't be swapped that way, so an
interrupted in-place rewrite could leave an authoring pack half-migrated. The
status is a problem status, so it counts against the run's exit code and shows
in the summary — the operator re-packs or migrates it as a `.feedpak` instead of
it vanishing from the report. Addresses a CodeRabbit review finding.

Signed-off-by: Kris Anderson <topkoa@gmail.com>

* fix(migrate): verify requires an explicit `off` on a retained full mix

verify_zip accepted any non-truthy `default` on a multi-stem `full` (missing,
empty, boolean, `false`/`no`/`0`, malformed) as "ok". But core defaults an ABSENT
`default` to True — ON (lib/sloppak.py: `s.get("default", True)`) — and treats an
empty/unrecognized string as ON too, so a migrated-shape pack whose `full` stem
has a missing or blank default beside instrument stems would actually play the
mixdown on open and double the song. verify was certifying that as safe.

Require an explicit normalized `off` beside instrument stems: `on`-ish values are
reported `full-stem-default-on` (actively plays), everything that is not a
normalized `off` is reported `full-stem-default-not-off`. The migrator already
writes the literal `off`, so its own output is unaffected; this also certifies
the pack is in the tool's canonical, most-portable shape. The len>1 gate is kept,
so a sole `full` stem (which IS the audio) is not policed.

Adds parametrized coverage for missing / empty / boolean / off-ish / malformed
defaults, and a sole-full-stem case. Addresses a CodeRabbit review finding.

fix(sloppak): bound the unpack cache; add read_member_bytes() so callers stop unpacking whole songs (#950)
* fix(sloppak): bound the unpack cache, and add a way to read a song without unpacking it

A tester's sloppak_cache reached 60 GB from an 1800-song library — his entire
library, unpacked, none of it played. Stems are already-compressed audio, so an
unpacked pack is ~1.1x its zip: the cache is a second, DECOMPRESSED copy of every
song it touches. It had no size cap, no LRU, and no cleanup of any kind — not even
when the song itself was deleted.

Two halves:

1. resolve_source_dir() now evicts least-recently-used songs to stay under a cap
   (FEEDBACK_SLOPPAK_CACHE_MAX_MB, default 4 GB ≈ 130 songs of recency; 0 disables).
   The sweep runs on unpack — the only moment the cache grows — so it can't drift.
   An evicted song is dropped from _source_cache too: get_cached_source_dir() is
   the only thing media.py consults before falling back, so a stale path there
   would 404 every stem for the rest of the process instead of re-unpacking.
   get_cached_source_dir() now also verifies the dir still exists, which makes
   "just delete sloppak_cache/ to reclaim disk" safe advice.

2. read_member_bytes() reads ONE file out of a pack without unpacking it — the
   same trick read_cover_bytes() uses so the library grid doesn't explode every
   pack to show a cover. Unpacking a whole song to read a few KB of JSON is ~45x
   write amplification; doing it in a loop over the library is what produced the
   60 GB. rig_builder's library-wide tone batch is the caller that did exactly
   that (fixed separately); this gives it, and everyone else, the right primitive.

Eviction is concurrency-safe: unpacks run 2-at-a-time, so a dir being written is
marked in-flight and the sweep skips it — checked and rmtree'd under one hold of
the guard, and the marker is released even if the unpack raises (a leaked marker
would make that dir permanently un-evictable).

read_member_bytes normalizes both the requested path AND the archive's stored
member names through safe_join, taking the last match — so './arrangements/x.json',
backslash members from Windows tooling, and duplicate members that normalize to
the same path all read back exactly as unpack-then-read did. Zip-slip is rejected
before anything is opened.

Tests: tests/test_sloppak_unpack_cache.py. All bite-tested (reverted each fix,
watched it fail) — including one that was passing vacuously: a freshly-unpacked
dir is the most-recently-used, so the LRU never reaches it and the in-flight race
test proved nothing until the packs were sized to force the sweep that far.

feat(library): effective genre falls back to MusicBrainz enrichment (#949)
* feat(library): effective genre falls back to MusicBrainz enrichment

Converted packs rarely carry a genres manifest key — on Byron's real
library 1188/1190 songs had no genre, starving the genre facet and the
career passport rack (2 usable genres) while song_enrichment already
held MB genres for 636 matched songs.

The effective-genre expression now resolves: per-song override → pack
genre → json_extract(enrichment.genres, '$[0]') for MATCHED rows only
(review/failed candidates could carry the wrong recording's genres).
Same fast-path gating as before: the plain indexed column is used
unless overrides or enrichment genres actually exist; stand-in DBs
without the table degrade via the OperationalError guard. Career
passports pick this up automatically through _effective_genre_expr().

Career v2, WS3. Bronze in blues/rock/metal/funk/jazz now also asks for
the genre's signature Virtuoso drill, data-driven in passports.json:
blues_shuffle, rock_power_backbeat, melodic_metal_gallop,
sixteenth_pocket, vl_shells — with career-side display labels the
passport page renders instead of raw node ids.

- virtuoso_nodes becomes {instrument: [node_ids]} so a keys passport
  never demands a guitar drill; a flat list keeps meaning guitar
  (virtuoso's content is guitar-first).
- _node_cleared also accepts keysCleared (a top-tier clean pass in one
  key — virtuoso's FIRST gained-only artifact). The depth rungs
  additionally require a maxed speed tier, too high a bar for Bronze.
- Genres without a curated entry stay songs-only.

feat(career): hours-per-genre odometer — honest wall-clock play time (#942)
Career v2, WS2. Nothing measured play time before (the achievements
plugin's final-position shortcut double-counts loops and mis-reads
seeks). Now:

- stats-recorder.js accrues WALL-CLOCK seconds across song:play/resume ↔
  pause/stop/ended spans (single spans clamp at 2h against suspend
  inflation) and piggybacks them as `seconds` on the POSTs it already
  sends; failed POSTs restore the accumulator; a session reset flushes
  first so time can't re-attribute to the next song/arrangement.
- POST /api/stats accepts optional `seconds` (finite, 0 < s ≤ 6h) on the
  scored and position branches, plus a new seconds-only branch for
  unscored plays that ran to the natural end — banks time WITHOUT
  touching the resume position (song:ended must not overwrite Continue)
  and still counts as playing today for the streak.
- song_stats gains additive idempotent `seconds_total`; record_session/
  touch_position accrue, new add_play_seconds() for the seconds-only
  path; the legacy-encoding stats merge sums seconds across duplicates.
- Passports surface it: "14.2 h in Blues" under the badge stamp and on
  the shelf cover sub-line — a true fact that only grows, never a
  target or a meter (Stage 5 post-cap, per the career design).

Tests: seconds accrual/validation/seconds-only branch (stats API),
per-instrument-and-genre summing (career), fmtHours formatting (vm).
Full suites: pytest 2480, JS 1165.

feat(career): passport backend — genre badges computed from stars (#935)
The badge-journey layer on top of career stars (Christian's career-mode
v2 design, composed with the shipped venue system). Badges are computed
on read from song_stats × the library's effective genre — never stored:
Bronze = N genre songs at min_stars (data-driven in passports.json,
default 5 songs at 2★) plus any configured virtuoso drill nodes.

New endpoints under /api/plugins/career/:
- GET  /passports        passport walls per instrument: badges, ticket
                         stubs (qualifying songs), library genres, drills
- POST /passports/commit instrument commitment (idempotent wax seal)
- POST /passports/open   open a genre passport (implies commitment)
- POST /drill-state      intake for the relayed virtuoso.progress
                         snapshot (career's frontend listens on the bus)

Instrument attribution reuses progression.instrument_for_arrangement via
the song_stats arrangement index; the genre column goes through the
host's override-aware effective-genre SQL. Non-graded instruments (bass,
drums) render shown-not-judged — repertoire, never a false badge denial.

Persisted state (commitments, opened passports, drill snapshot) lives
under CONFIG_DIR/career/ and rides the settings export bundle via
settings.server_files; a minimal settings.html documents it.

0158286d06 ci: flow-aware manifest discovery — a name list missed real readers
Review found lib/routers/chart.py binding `m = load_manifest(p) or {}` and
reading eight manifest keys through it. `m` was not in MANIFEST_VARS and
`m.get` did not match the readers-complete regex, so the module was
invisible to BOTH halves of the gate — unlisted and unscanned. Same for
lib/routers/song.py (binds `manifest` from load_manifest for enrichment
gap-fill). Both are now in READERS.

The structural fix, not the name-list patch: keys_touched() now discovers
receivers flow-aware — any local assigned from load_manifest(...) is a
manifest dict, whatever it is called. MANIFEST_VARS remains only as the
fallback for manifests that arrive as function parameters (ws_highway).
A plain `m = {}` is not a receiver; test pins that.

readers-complete now reuses keys_touched() itself instead of a parallel
KEY_OPS regex — the two detectors diverged once already (that is exactly
how chart.py slipped through), so now there is one detector and one truth.

check_reverse() gets a 300s subprocess timeout: the validator executes at a
pinned SHA, but a pathological pack or validator bug should fail the job,
not hang the runner to the Actions-level timeout.

Tests: flow-aware receiver under an arbitrary name (read + write), and the
negative — a plain dict named `m` stays out of the scan. 17 pass.

b54b65d35c test: give the spec gate its own regression suite
Self-review finding: the gate is what keeps the app from drifting off the
feedpak spec, but the gate itself had zero pytest coverage — a refactor
could quietly weaken keys_touched or the allowlist logic and nothing would
notice. The protector needs protecting.

tests/test_spec_gate.py pins the load-bearing behaviours:

- read/write classification: get() reads; subscript Store and setdefault()
  write (the two forms that were blind spots in review); the
  load_manifest-wrapped get; unrelated dicts and non-literal keys ignored.
- exceptions file: duplicate keys and issue-less entries rejected.
- the closed allowlist: growth fails, shrink and steady state pass,
  bootstrap skips.
- live-tree checks, same as CI: READERS matches the codebase, and the only
  non-spec key core touches is the grandfathered original_audio.

Also fixes stale "Layer 2/3" docstrings on check_forward/check_reverse
(they are layers 3/4 since allowlist-closed landed) — the same
docs-lag-the-code class this PR's review kept catching; now the numbering
is asserted by the printed [n/4] headers next to them.

* feat(career): career plugin — stars from song_stats, venue tiers, pack downloads (career mode PR2)

Bundled plugin: per-song stars from best_accuracy (60/75/85% → 1/2/3★),
cumulative stars unlock bar → club → arena (data-driven venues.json).
Venue packs (UE-rendered crowd loops) download on demand to
CONFIG_DIR/plugin_uploads/career/ on a background thread with sha256 +
zip-slip validation, served via FileResponse. Career screen (promoted
sidebar entry) shows progress and pushes the active venue's manifest

either side is absent. Pack URLs land in venues.json in PR3.

superseded.

- Pack manifests may ship an intro block (flyover video + ambience mp3);

feat(venue): reactive crowd video layer behind the 3D highway (career mode 1/3) (#905)
* feat(venue): reactive crowd video layer behind the 3D highway (career mode PR1)

Two crossfading video backdrop planes in the highway_3d venue background
style, driven by a new venue-crowd.js state machine that maps
v3:live-performance-state to crowd states (bored/neutral/engaged/ecstatic)
with 3s stability + 8s dwell hysteresis, plus one-shot reaction stingers
on streak milestones and end-of-song accuracy. Inert without a venue pack
manifest (career plugin, PR2) or the feedBack-venue-crowd-dev flag — the
static bg plate behaves exactly as before.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): retry renderer binding + preserve mid-stinger transitions

Codex preflight P2s: (1) videos created before highway_3d registered its
globals never reached the backdrop planes — binding is now idempotent and
retried from start/perf-event/re-activation paths; (2) a crowd-state
switch committing while a stinger played was dropped because the machine
had already advanced — it is now deferred and played when the stinger ends.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): per-video load tokens + unbind renderer on stop

Codex preflight round 2: (1) the global load token let a stinger cancel a
committed loop load on the other layer — tokens are now per-element, and a
stinger preempting an in-flight loop on its own layer requeues that loop
for when the stinger ends; (2) setManifest(null)/deactivate left the last
crowd frame bound and visible over the static plate — stop() now unbinds
both layers from the renderer and zeroes the mix.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): flush deferred loop on stinger failure, source accuracy from perf events

Codex preflight round 3: (1) a failed/timed-out stinger left a deferred
loop switch queued forever; the failure path now flushes it. (2)
stats:recorded only carries {filename, arrangement}, so the end-of-song
reaction now uses the accuracyPct from the song's last
v3:live-performance-state event (a real percentage) instead of a field
that never existed.

* fix(venue-crowd): requeue mid-crossfade loops preempted by stingers; hard-stop on manifest swap

Codex preflight round 4: (1) idleLayer() still points at the fading-in
layer during a crossfade, so a stinger firing mid-fade overwrote the new
loop with nothing requeued — the fading loop is now tracked and requeued
like an in-flight load; (2) swapping venue packs while active now goes
through stop() so _stopGen invalidates the old manifest's in-flight loads.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): generation-gate stinger handlers; recrop on video size change

Codex preflight round 5: (1) an ended/timeout handler orphaned by stop()
could fire into a later stinger's lifecycle on the reused element — handlers
now detach unconditionally and carry a generation token; (2) the renderer
only re-applied cover-crop on camera aspect changes, so a src swap with a
different intrinsic size kept stale repeat/offset — it now recrops when
videoWidth/Height change.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): bail loop-fade completion when a stinger preempted the layer

Codex preflight round 6: the loop crossfade's completion callback could
still run between a stinger's start and its canplaythrough, promoting the
stinger's layer to active and pausing the real loop — it now bails when
the fading loop was preempted.

* fix(venue-crowd): keep rear video layer opaque during crossfades

Two half-transparent layers let the static bg plate bleed through (~25%
at mid-fade) — visible as a flash of the old still image on every state
transition. The crossfade is now always the front layer fading over an
opaque rear layer.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): reset active layer with mix on stop

Codex preflight: stop() zeroed the mix but left _activeLayer at 1, so a
restart flashed layer 0's stale frame until the new loop loaded.

* fix(venue-crowd): reset crowd mood to neutral on song load

Codex preflight: a song ending in ecstatic/bored left the next song's
crowd stuck in that mood until the hysteresis window passed.

* fix(venue-crowd): cancel in-flight fade when a stinger preempts it

Codex preflight: the orphaned ramp kept pushing the mix toward the layer
whose src the stinger had just replaced.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): don't let null accuracy resets wipe the end-of-song value

Codex preflight: Number(null) is 0, so idle HUD resets overwrote
_lastAccuracyPct before stats:recorded consumed it, suppressing the
end-of-song stinger.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): abort stale stinger state on song load

Codex preflight: a stinger straddling a song change could fade back into
the previous song's layer or flush its pending loop.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* fix(venue-crowd): always detach load listeners, gate only the callback

Codex preflight: superseded loads left canplaythrough/error listeners
attached to the persistent video elements — unbounded growth over a
session.

* feat(venue-crowd): flyover intro with crowd-ambience ducking

On song:loaded, an optional pack intro plays once: a camera flyover video
(idle layer, one-shot) with bar-crowd ambience audio that ducks out on
song:play, near the flyover's landing, or at handoff — whichever first.
Machine commits and stingers defer during the intro; stop()/song-change
abort it. Packs without an intro behave as before.

ffc52f13ce Harden freqs_to_midis against NaN/Inf; badges read exact tuningMidis
Follow-ups to #829 (CodeRabbit's review nit + the consumer adoption the PR

- freqs_to_midis: reject non-finite frequencies (NaN/Infinity) — a provider
  handing one through would otherwise raise inside int(round(...)) and 500
  GET /api/tunings. Tests cover nan/inf/-inf alongside the existing garbage
  cases.

- v3 instrument badge: TUNING_NOTE now prefers the exact integer midis the
  server serves (tuningMidis) over reconstructing the note from the lowest
  string's frequency via log2 against a hardcoded 440 — which can land a
  semitone off at non-440 reference pitches. Frequency path kept as the
  fallback for older cached responses.

fix(nav): nobody may monkey-patch window.showScreen — add screen:changing, make the shell listen (#924) (#925)
Some checks are pending
ship-ci / ci (push) Waiting to run
* fix(nav): the library sometimes showed the legacy screen — map 'home' inside showScreen

Testers: "randomly, when moving to the library from another menu option, the library shows the
old interface — never when a song ends."

━━━ WHAT WAS ACTUALLY HAPPENING ━━━

#home is the PRE-V3 library screen. The v3 shell replaced it with #v3-songs, and the mapping DID
exist — but only inside WRAPPERS on window.showScreen, and only for callers that go through
`window`. THREE independent parties monkey-patch it, each capturing whatever happens to be there
at the time:

    app.js publishes the raw function
      -> shell.js wraps it, adding the home -> v3-songs mapping
      -> the stems plugin wraps it AGAIN (src/main.js:1029), capturing the current value

Plugins load ASYNCHRONOUSLY. The chain links up in whatever order the race settles, and any
capture taken before shell.js installs — or any re-assignment after it — silently drops the
mapping. Hence "randomly".

AND THE INTERNAL CALLERS NEVER TOUCHED window.showScreen AT ALL. closeCurrentSong and the
Esc-from-settings shortcut call the IMPORTED showScreen, which no wrapper ever sees. Reproduced
in a browser: the unwrapped function with 'home' lands on the dead legacy screen EVERY time.

"Never when a song ends" is the tell, and it is what identified the mechanism: closeCurrentSong
resolves its target through _resolvePlayerOrigin(), which ALREADY applies this mapping. That one
path was fine — which is exactly why the bug looked random rather than total.

PRE-EXISTING, not a regression from the module carve: the onclick="showScreen('home')" links and
the wrapper-only mapping both date to 2026-06-22.

━━━ THE FIX ━━━

The guard lives inside showScreen now: ONE place, in the function every caller routes through,
instead of a chain of monkey-patches that must each remember. Wrapper order stops mattering, and
the module-internal callers are covered for the first time.

Verified in a browser: the raw, unwrapped showScreen('home') — which reproduced as #home — now
lands on #v3-songs, and cannot be undone by any wrapper order.

━━━ AND A [P1] I INTRODUCED, WHICH CODEX CAUGHT ━━━

My first cut mapped BOTH 'home' and 'v3-home', copied straight from _resolvePlayerOrigin.

That is correct THERE and wrong HERE. _resolvePlayerOrigin computes where to RETURN TO after a
song, and landing on the Songs list from the dashboard is the right behaviour. But #v3-home is
the v3 DASHBOARD — a real screen that the shell's Home nav, the onboarding tour and the dashboard
re-render listener all target. Redirecting it would have made Home unreachable.

A LEGACY ALIAS IS NOT THE SAME THING AS A RETURN TARGET. Only 'home' is mapped now, and a test
pins that: re-adding 'v3-home' to the guard fails it.

4 tests, bite-tested both ways.

* fix(nav): nobody may monkey-patch window.showScreen — add screen:changing, make the shell listen (#924)

window.showScreen was wrapped by THREE independent parties, each capturing whatever happened to be
there at the time:

    app.js publishes the raw function
      -> static/v3/shell.js wrapped it (to call syncActive, and to map home -> v3-songs)
      -> the stems plugin wrapped it AGAIN (to tear down on leaving the player)

Plugins load ASYNCHRONOUSLY, so the chain linked up in whatever order the race settled. A capture
taken before shell.js installed silently dropped the mapping it carried — and the library opened on
the dead legacy #home screen. Testers saw that as "randomly, the library shows the old interface"
(#923).

#923 fixed the symptom by moving the mapping inside showScreen. This removes the CAUSE: neither
wrapper ever needed to be one.

━━━ TWO EVENTS, AND THE DISTINCTION IS THE WHOLE POINT ━━━

    screen:changing  emitted BEFORE anything happens. "I am leaving `from`." Teardown/cancel here.
    screen:changed   emitted after the DOM and data settle. "I am on `id`." Now carries `from`.

screen:changing is new, and it exists because Codex caught me collapsing the two. The stems plugin
tore down its audio graph BEFORE showScreen did anything; screen:changed fires at the very END,
after core awaits library and provider loads — so moving the plugin onto it would have delayed
teardown behind a slow fetch, or skipped it entirely if that fetch threw, and stems would keep
playing on a non-player screen. A test pins the ordering: screen:changing must precede the first
await.

shell.js is a plain screen:changed listener now, like app.js, audio-mixer.js and tour-engine.js
already were. window.showScreen is an unwrapped function again, and tests/js/
no_showscreen_monkeypatch.test.js fails CI if anything in static/ ever assigns to it again — so the
hazard is structurally impossible rather than merely avoided.

━━━ AND A FALLBACK THAT COULD NEVER FIRE ━━━

My retry-if-the-bus-is-late path listened for `slopsmith:capabilities:ready`. Core dispatches
`feedBack:capabilities:ready` (capabilities.js:1536) — the slopsmith: name is the PRE-DMCA event
and nothing has emitted it since the rename. Codex caught it. A guard that cannot fire is worse
than no guard: it reads as protection and is decoration.

(The same dead-event bug turned out to be sitting in THREE of the stems plugin's fallbacks, where
it has silently disabled its lifecycle wiring whenever the bus was late. Fixed in
feedback-plugin-stems#38.)

VERIFIED. A/B against origin/main: the nav highlight and topbar title follow IDENTICALLY with
shell.js as a listener; screen:changing -> screen:changed fire in order with the right {id, from};
window.showScreen is unwrapped; and showScreen('home') still lands on v3-songs.

refactor(app): carve the song session out of app.js — playSong, showScreen, closeCurrentSong (R3d) (#921)
36 declarations + the 4 autoplay/auto-exit gate statements. 359 lines.
app.js 3,772 -> 3,242. Bodies VERBATIM.

━━━ THIS WAS "THE UNCUTTABLE HEART", AND IT IS 359 LINES ━━━

At the start of this epic, seeding a dependency closure from count-in, from loops, from
section-practice, or from the JUCE seek shim all returned the SAME 178-function, 3,360-line set.
playSong and showScreen called each other; everything called them; nothing could be cut anywhere.
The conclusion — correct at the time — was that NO closure-based carve could touch it at any
seed, and the answer was a host seam.

That was true THEN. Every slice taken out since (transport, loops, count-in, section-practice,
the library, the edit modal, settings) removed edges, and the strongly-connected component
DISSOLVED. This closure is 36 declarations with an interface width of FOUR.

The lesson is not that the seam was wrong — the seam is what MADE this possible, by letting the
carves proceed against a cyclic core instead of stalling on it. The lesson is to RE-MEASURE. An
SCC is a fact about a graph at a moment, not a property of the code.

━━━ THE BUG NO SCAN COULD SEE, AND THE A/B DID ━━━

First cut passed every gate — no-undef clean, no-cycle clean, 1045/1045, pytest green — and
THREW IN THE BROWSER: "Assignment to constant variable."

window.feedBack.holdAutoplay / holdAutoExit and their two event handlers are TOP-LEVEL
STATEMENTS, not declarations. They WRITE this cluster's state (_autoplayHeld, _autoExitTimer, …),
and an imported binding is READ-ONLY — so left behind in app.js, every one threw the instant the
module existed.

A dependency scan that walks DECLARATIONS cannot see them. Mine didn't. This is the same blind
spot that nearly shipped a dead library A-Z rail (#896): app.js keeps its public API in top-level
statements, and a call-graph is blind to every one of them.

The extractor now finds them by construction — any top-level statement that WRITES a moved
binding comes with the carve — and the gate statements live beside the machinery they drive,
which is where they belonged anyway.

━━━ ZERO OUTSIDE WRITES, BY MOVING THE BOUNDARY RATHER THAN BUILDING MACHINERY ━━━

The autoplay scalars and the wake-lock state were written from outside the cluster, which would
have forced a setter or a state container. But the writers — _releaseAutoplay, _acquireWakeLock —
plainly belong here. Pulling them in left ZERO outside writes, so every export is a plain import.
Same move as settings (#920): measure the writers before you reach for a container.

VERIFIED. A/B against origin/main in two browsers, IDENTICAL, zero page errors — including the
autoplay gate driven end to end: a plugin HOLDS autoplay, the song loads but does not start, the
RELEASE fires it, and a stale release is a no-op. That is the exact machinery that was throwing.

refactor(app): carve settings into static/js/settings.js (R3d) (#920)
22 declarations, 446 lines. app.js 4,218 -> 3,772. Bodies VERBATIM.

Settings load/save, the AV-offset nudge, the default-arrangement pin, the instrument pathway,
and the app-update channel.

━━━ INTERFACE WIDTH 1, AND IT GOT THERE BY DRAWING THE BOUNDARY IN THE RIGHT PLACE ━━━

app.js calls loadSettings() and nothing else.

The first cut was NOT clean: _defaultArrangement was written from OUTSIDE the cluster, and an
imported binding is READ-ONLY, so that one write would have forced a setter or a state
container — as it did for the player (player-state.js) and the library (library-state.js).

But the writers were saveSettings and pinCurrentArrangementDefault, which ARE settings
functions. Widening the slice to include them left ZERO outside writes. Every export is now a
plain read-only import and no container is needed.

Worth naming, because I reached for a container twice before: the fix for "this binding is
written from outside" is sometimes a container, and sometimes it just means the boundary is in
the wrong place. Measure the writers before you build machinery.

━━━ handleSliderInput STAYS A HOST HOOK, DELIBERATELY ━━━

It lives in settings now (it is a settings control), but player-controls.js must NOT import it:
this module already imports player-controls (_applyMastery, _autoplayExitEnabled, …), so a
direct back-import would close a cycle. player-controls keeps reading it through the host seam,
and app.js — the root, which imports both — wires it. That is exactly what the seam is for, and
the contract test proves the wiring survived.

VERIFIED. A/B against origin/main in two browsers: the window contract, the settings screen
rendering, the AV-offset and default-arrangement controls present, and a real `input` event
dispatched on a slider — which is the path that goes through the host seam. IDENTICAL, zero

refactor(app): carve the edit-song modal into static/js/edit-modal.js (R3d) (#919)
4 functions, 234 lines. app.js 4,452 -> 4,218. Bodies VERBATIM.

INTERFACE WIDTH ZERO — nothing in app.js calls into this cluster. app.js needs only the names
on the window contract, so the markup's onclick= handlers resolve. That is what makes it the
cleanest slice left.

AND IT ONLY BECAME CLEAN BECAUSE THE LIBRARY CAME OUT FIRST (#896). Every dependency the modal
has is a module now: it reads six bindings out of ./library.js (loadLibrary, loadFavorites,
loadTreeView, _removeLibCardsForFilename, libView, _lastLibSelected) plus dom.js and the L
container. Before that carve, extracting this would have dragged the whole library with it.

Checked, and it matters: the modal never WRITES any of those six. An imported binding is
READ-ONLY, so a single write would have forced a setter or a state container. Every use is a
read, so plain imports suffice.

Acyclic: edit-modal -> { dom, library-state, library }, and library imports none of them back.

VERIFIED. A/B against origin/main in two browsers: the window contract, the modal actually
OPENING off a real library row, its title and year fields rendering, and the data-edit-save
wiring (rather than an inline onclick embedding the filename — the fix this cluster's harness
exists to guard). IDENTICAL, no new page errors.

fix(tailwind): stop the dev server rewriting a tracked file (#911) (#918)
The runtime stylesheet moves to CONFIG_DIR. static/tailwind.min.css is never written again.

━━━ TWO DIFFERENT THINGS WERE SHARING ONE PATH ━━━

    static/tailwind.min.css   a BUILD ARTEFACT. Committed, image-baked, generated by scanning
                              the in-tree plugins only. CI's tailwind-fresh check verifies it.
    the RUNTIME sheet         PER-INSTALL STATE. Additionally scans whatever the user installed
                              into FEEDBACK_PLUGINS_DIR, so it differs machine to machine.

Writing the second over the first meant that MERELY RUNNING THE DEV SERVER from a git checkout
silently modified a tracked file. `git add -A` then swept a 100KB reshuffle of minified CSS
into the commit and ci/tailwind-fresh went red with a diff that explains nothing — on a PR
whose real change touched no Tailwind classes at all. It also wrote app state into the app
directory, which is read-only in some deploys.

A new route serves the runtime sheet when there is one and falls back to the committed one
otherwise. It is registered BEFORE the /static mount, which would otherwise swallow the path.

━━━ A PERSISTED SHEET MUST NOT OUTLIVE ITS REASON (Codex [P2] x2) ━━━

1. THE USER REMOVES THEIR PLUGINS. Startup only rebuilds when user plugins exist, so nothing
   would ever overwrite the stale sheet — and it still carries classes for plugins that are
   gone. With no user plugins the COMMITTED sheet is complete by definition. Guarded.

2. THE APP IS UPGRADED, and my first guard for this was WRONG. I compared mtimes. Codex: that
   is not a freshness signal across install methods — archives and container images routinely
   PRESERVE SOURCE MTIMES, so a just-shipped stylesheet can carry an OLDER timestamp than a
   runtime sheet a user built days ago. The mtime check then calls the stale one FRESH and it
   masks the new core CSS indefinitely — permanently, if no Tailwind toolchain is present to
   trigger a rebuild.

   Freshness is decided by CONTENT now. Each runtime build stamps a sidecar with the sha256 of
   the committed sheet it was made from. Core ships new CSS -> that file changes -> the hash
   changes -> the runtime sheet is correctly judged stale. Timestamps only gesture at the
   question that hashing answers.

Falling back to the committed sheet is always safe: at worst it lacks a just-installed plugin's
classes for the seconds until the async rebuild lands.

VERIFIED END TO END. Ran the real dev server with 3 plugins installed: it rebuilt Tailwind over
them (123,291 bytes), wrote the sheet + sidecar to CONFIG_DIR, still served /static/
tailwind.min.css at 200 — and `git diff` on the tracked file came back CLEAN.

8 tests. Bite-tested: reverting to the shared path fails 3, dropping the staleness guards fails
2 more.

Closes #911

refactor(highway): carve the 2D drawing layer into highway-draw.js (R3c) (#917)
18 functions, 1,245 lines. highway.js 3,972 -> 2,727 (-31%). The biggest R3c slice: notes,
sustains, chords, strum groups, unison bends and lyrics — everything the default renderer
paints each frame.

━━━ MUTABILITY, NOT LOCATION, DECIDES WHERE A THING BELONGS ━━━

Three per-instance caches came out with this slice, and they are why it needed care:

    _frameMismatchWarned   a warn-once Set of chord ids     (feedBack#88)
    _chordRenderInfo       a WeakMap of chord -> chain info
    _lyricMeasureCache     Map<fontSize, Map<text, width>>

All three are MUTATED. Left at module scope they would be SHARED ACROSS PANELS — one
highway's lyric widths and chord chains stomping another's, silently, with nothing throwing.
createHighway() is a factory (the constitution publishes window.createHighway so a plugin can
build a second highway), so they are lifted onto hwState, which is exactly what hwState is for.

The shimmer LUT went the OTHER way — to MODULE scope in highway-geometry.js. It is a
deterministic xorshift table, byte-for-byte identical for every instance, so sharing it is not
merely safe but BETTER: built once for the page rather than once per panel.

Same slice, opposite directions, decided entirely by whether the thing mutates.

━━━ MY SCRIPT WAS WRONG TWICE. THE GATES CAUGHT BOTH. ━━━

1. HAND-LISTED THE MOVE SET. I listed 10 functions and missed six that drawChords needs
   (_ensureChordRenderCache, bsearchChords, getChordTemplateInfo, _computeChordBox,
   _updateFretLinePreview, _drawFretLineChordPreview). The no-undef gate named every one. The
   set is now DERIVED from the dependency closure — 18, not 10.

2. JUDGED PURITY TOO EARLY, and this one is subtle. I classified _computeChordBox as pure
   because its ORIGINAL body never mentions hwState. Then the call-site rewriter injected
   `fretX(hwState, …)` INTO it — fretX takes hwState now (#916) — leaving a function that
   references an hwState it was never given. Purity has to be judged from the body AS IT WILL
   BE, so the classifier iterates to a fixed point: a function needs hwState if it mentions it,
   OR calls anything that now takes it. That moved _computeChordBox to the stateful side.

VERIFIED. A/B against origin/main: IDENTICAL, zero page errors. The PLUGIN BUNDLE contract is
byte-identical (b.fretX arity 3, b.getNoteState arity 2, both stable references, both correct
under the old calling convention). PERF GATE PASSES AT 1.92ms against its 12ms budget — and
this is the slice that could really have cost something: the ENTIRE per-frame drawing path is
now cross-module. It costs nothing measurable.

TESTS. highway_teaching_marks follows strumGroupBuckets to the new module. The two source-shape
harnesses now read highway.js AND every static/js/highway-*.js, rather than being re-pinned at
whichever file currently holds a function — re-pinning breaks again next time, and a shape
assertion that silently stops finding its target is indistinguishable from one that passes.

refactor(highway): carve the STATEFUL primitives, threading hwState explicitly (R3c) (#916)
fretX, fillTextReadable, _noteState, _paintGemGlow -> static/js/highway-state-primitives.js.
50 call sites rewritten. highway.js 4,105 -> 3,965.

The first slice that changes signatures. Each of these four gains hwState as an explicit
FIRST PARAMETER.

━━━ hwState IS A PARAMETER, NOT AN IMPORT ━━━

createHighway() is a FACTORY. The constitution publishes window.createHighway so a plugin can
build a SECOND highway for its own panel, and highway.js says so itself. Import hwState as a
module singleton and two panels silently share one clock, one render scale, one string
palette — each driving the other. Nothing throws. The picture is just wrong, in a way no test
would catch.

(The exact opposite of the app.js carve, where player-state.js and library-state.js ARE
module singletons — correctly, because there is exactly one app. Same epic, same language,
opposite answer, decided entirely by whether the thing is a factory.)

━━━ THE PLUGIN BUNDLE NEARLY BROKE, SILENTLY ━━━

The renderer bundle hands two of these STRAIGHT TO PLUGINS:

    b.fretX = fretX;
    b.getNoteState = _noteState;   // stable reference

highway_3d calls both EVERY FRAME, with the old arity. Handing out the new 3-arg versions
would have passed `note` where hwState belongs — no throw, no error, just wrong geometry and
wrong judgment state INSIDE A PLUGIN, which no core test would ever see. Green CI, broken 3D
highway.

So hwState is bound ONCE per instance, in the factory, and the bundle hands out those views.
A per-frame arrow would have fixed the arity and reintroduced exactly the per-frame allocation
the bundle's stable-reference contract (feedBack#254) exists to prevent. b.project needs none
of this — project() is pure and its arity never changed.

VERIFIED IN A BROWSER, against the real bundle, on both builds:

    fretX arity                      3    3     (NOT 4 — the bound view preserves it)
    getNoteState arity               2    2
    fretX(5,1,800) in 0..800      True True
    getNoteState null w/o provider True True
    getNoteState honours provider  True True
    fretX is a stable reference    True True

IDENTICAL. Without the bound views fretX would have reported arity 4 and computed garbage.

Also caught on the way: my generated module imported STRING_BRIGHT_FALLBACK, a name
highway-constants.js does not export. ESLint does not flag that — but importing a name a
module does not export is a runtime SyntaxError that kills the WHOLE module. These four need
no constants at all; the import is gone.

TESTS. highway_note_state pins the signature AND the stable-reference contract — it caught the
bundle break. Retargeted at the module and the new arity; both contracts still asserted, and
the "no fresh arrow per frame" rule is now asserted explicitly rather than implied by
`getNoteState: _noteState`.

PERF GATE PASSES AT 1.94ms against its 12ms budget — fretX and _noteState are now CROSS-MODULE
calls, per note, per frame. It costs nothing measurable.

refactor(highway): carve the PURE geometry primitives into highway-geometry.js (R3c) (#915)
6 functions, 53 lines. highway.js 4,158 -> 4,105. NOT ONE CALL SITE CHANGES.

project, roundRect, bnvNormalizedPoints, teachingFingerLabel, teachingDegreeLabel,
chordHarmonyLabels — the shared primitives every drawing function leans on.

━━━ PURITY IS THE WHOLE POINT OF THIS SLICE ━━━

Every one of these is a pure function of its arguments. None touches hwState. None closes over
the canvas context — roundRect() already took `ctx` explicitly, and the rest need nothing but
numbers. project() reads only the module-level constants from #914.

That matters because createHighway() is a FACTORY: a plugin can build a second highway for its
own panel, so anything holding per-instance state must be PASSED hwState rather than importing
it, or two panels silently share one clock and palette. These six hold no state at all, so
they move VERBATIM — the module boundary is invisible to every caller.

The asserts are mechanical and in the extractor: it REFUSES to move a function whose body
mentions hwState, or that references `ctx` without taking it as a parameter. Purity is
checked, not assumed.

━━━ WHAT IS DELIBERATELY LEFT BEHIND ━━━

The four primitives that DO need hwState — fretX, fillTextReadable, _noteState, _paintGemGlow
— stay in the factory for now. They need an explicit hwState parameter threaded through 53
call sites, which is a real behavioural change and belongs in its own commit rather than
smuggled in beside a provably-identical move. Separating the provable from the risky is the
whole discipline of this epic.

TESTS. Three harnesses brace-match these functions out of the source and run them in a
sandbox; they now read static/js/highway-geometry.js. `export function x` still contains
`function x`, so the extractor needed no change — only the path.

VERIFIED. A/B against origin/main: 15 probes IDENTICAL, zero page errors. PERF GATE PASSES AT
1.91ms against its 12ms budget — and this is the one that could plausibly have cost something:
project() runs for every visible note on every frame and is now a CROSS-MODULE call. It costs
nothing measurable. That is the answer #910 was built to give.

refactor(highway): carve the constants into static/js/highway-constants.js (R3c) (#914)
29 constants, 190 lines. highway.js 4,267 -> 4,158. The first real slice, and the one that
every later one imports.

━━━ WHY ONLY THE CONSTANTS MAY LIVE AT MODULE SCOPE ━━━

createHighway() is a FACTORY, not a singleton. The constitution publishes
window.createHighway precisely so a plugin can build a SECOND highway for its own panel, and
highway.js already says so at the top of the closure:

    // R3c: per-instance mutable state in one object, so extracted renderer/ws
    // modules can close over it as a factory arg without cross-panel sharing.

So hwState — all 79 mutable properties — must NEVER become a module-level singleton: two
highways would silently share it, and one panel would drive the other's clock, scale and
colour tables. Extracted functions will take it as an ARGUMENT.

That is the OPPOSITE of the app.js carve, where a single state container (player-state.js,
library-state.js) was exactly right, because there is exactly one app. Same epic, same
language, opposite answer — because one is a singleton and the other is a factory.

These 29 are pure literals: numbers, strings and colour tables, never reassigned, never
mutated. Sharing them across instances is not merely safe, it is what you want — one copy of
the shimmer LUT bounds and the string palettes rather than one per panel. Anything with a
runtime dependency (document, window, performance, localStorage) stays in the factory;
checked, and none of these has one.

ESLint now knows static/highway.js is a module. It could not have known before this commit:
the flip (#913) changed the SCRIPT TAG, but the file had no import/export yet, so it still
parsed as a script and lint stayed green. The first `import` is what makes the config wrong.

TESTS. Four source-shape harnesses asserted `const _AUTO_SCALE_MIN = …` etc. lived in
highway.js. They now read highway.js AND every static/js/highway-*.js — deliberately, rather
than being re-pinned at whichever file currently holds a constant. Re-pinning just breaks
again on the next carve, and a source-shape assertion that silently stops finding its target
is indistinguishable from one that passes. Bite-tested: renaming two constants away fails
them.

VERIFIED. A/B against origin/main: 15 probes IDENTICAL, zero page errors. AND THE PERF GATE
PASSES AT 1.97ms against its 12ms budget — which is the point of having built it (#910)
first: these constants moved from closure scope to module scope, and V8 does not treat those
identically. It does here. Now I know rather than hope.

refactor(highway): make the highway global explicit before the module flip (R3c) (#912)
73 bare `highway.x` references -> `window.highway.x`, across app.js and 10 other files.
Provably a NO-OP today. It is the precondition for flipping highway.js to a module.

━━━ WHY THIS HAS TO LAND FIRST ━━━

highway.js is a CLASSIC script. Its top-level `const highway = createHighway()` therefore
creates a GLOBAL LEXICAL BINDING — visible as a bare name to every other classic script AND
to every ES module. 73 call sites quietly rely on that.

The moment highway.js becomes a module, that binding is gone. `const` in a module is
module-scoped, not global. Every one of those 73 sites becomes a ReferenceError, and the
flip is impossible until they say what they mean.

`window.highway = highway` is already set, to the same object, on the same line. So this is
an identity rewrite — verified in the browser below.

━━━ THE REWRITE BIT ME THREE TIMES. REGEX IS NOT ENOUGH FOR THIS. ━━━

1. A SHADOWED LOCAL. capabilities/note-detection.js does `const highway = window.highway`.
   Its 9 bare uses are LOCAL and already correct; a blind rewrite would have emitted
   `const window.highway = window.highway`. Excluded.

2. HALF-CONVERTED GUARDS — the dangerous one. Six sites read
   `typeof highway !== 'undefined' && highway && typeof highway.setTime === 'function'`.
   The regex converted the CONSEQUENT and left the TEST, which is WORSE than not touching
   them: after the flip `typeof highway` is 'undefined', so each guard is PERMANENTLY FALSE
   and the code behind it silently never runs. transport.js's was the seek->setTime sync:
   the chart clock would have quietly desynced after every seek, with nothing failing.
   All six now test window.highway.

3. TWO MORE BARE REFERENCES, found by Codex [P2] and confirmed by an AST scan: app.js:3114
   and :3176 use `highway && typeof window.highway.getSections === 'function'`. My grep
   searched for `typeof highway`, not `highway &&`. After the flip these throw, the catch
   swallows it, and the editor silently falls back to a ±4s edit window and arrangement 0.

Regex missed a shadow, a half-conversion, and two bare reads. The final check is an
AST pass that resolves scopes and reports every `highway` identifier not bound locally.
It now reports ZERO.

VERIFIED. A/B against origin/main in two browsers, 15 probes, IDENTICAL, zero page errors:
window.highway is the same object as the bare global, the whole API surface resolves, a real
song plays, the chart clock advances, getPerf().drawMs > 0 — and `seek syncs chart` passes,
which is the exact guard I nearly broke in (2).
