34215fbd32 fix(static): request raw stereo audio for the loopback capture track
Chromium treats a getDisplayMedia audio track as a voice call by
default: echo cancellation, noise suppression, auto gain control and
mono downmix. Music through that pipeline is the tester-reported
"tin can" sound on ASIO/exclusive outputs.

Request the raw path explicitly (EC/NS/AGC off, stereo, 48 kHz) —
all constraints are best-effort so unsupported ones degrade silently
instead of failing the capture. The [asio-diag] loopback line now
dumps track.getSettings() so logs prove which processing actually
applied.

fix(plugins): make a module plugin actually re-evaluate on reload (#879) (#897)
A plugin reload silently did nothing for scriptType:"module" plugins. ES modules are
evaluated ONCE PER URL PER DOCUMENT, so re-inserting a <script type="module"> whose src
the module map has already seen fires `load` without re-running the body — and the loader
then recorded the reload as applied. A no-op that reported success.

THE ISSUE UNDERSTATES IT. #879 says "upgrades are fine — a new version yields a new URL".
That is true of screen.js and FALSE of the plugin. I drove a real browser through
install(1.0.0) -> upgrade(1.1.0) -> rollback(1.0.0), counting evaluations of src/main.js:

    ONE.

Not three, not two. The upgrade re-runs the one-line screen.js shim at its new ?v= URL;
the shim does `import './src/main.js'`; a relative specifier resolves against the base URL
WITH THE QUERY DROPPED; that is the same URL as before; the module map hands back the
already-evaluated v1.0.0 module. The plugin's own code never re-ran. Busting the entry
point cannot fix this, whatever token you hang off it.

So the token goes in the PATH: /api/plugins/<id>/g/<n>/screen.js. From there
'./src/main.js' resolves to /api/plugins/<id>/g/<n>/src/main.js — every relative import
inherits it, at every depth, for free. No import-specifier rewriting (which could never
see `import(expr)` anyway). Same browser drive after the fix: THREE evaluations.

Keyed on the plugin ID, not id@version: EVERY re-load of a module plugin needs a fresh
path, not just a rollback. First load keeps the stable ?v= URL, so the ETag/304 live-edit
caching the R0 rails depend on is untouched. Classic-script plugins are not affected and
never take a /g/ path.

━━━ A PATH REWRITE, NOT TWO MIRRORED ROUTES ━━━

Codex caught this, and it was right. The token shifts the BASE URL, so EVERYTHING the
module graph resolves relatively moves with it — not only imports.
`new URL('../assets/worklet.js', import.meta.url)` from /api/plugins/x/g/1/src/main.js
resolves to /api/plugins/x/g/1/assets/worklet.js. Mirroring only screen.js and src/ would
have fixed imports and 404'd every asset, worklet and wasm file the graph reaches — and
would have broken again the next time someone added a plugin route.

So the /g/<token> segment is STRIPPED BEFORE ROUTING. Every plugin route, present and
future, works under the prefix with no extra wiring. The token is opaque and never joined
into a filesystem path, so containment still rests entirely on the same safe_join.

Codex then caught a [P3] in that: eagerly re-encoding raw_path with latin-1 raises
UnicodeEncodeError on a valid plugin file like src/工具.js, 500ing a request the plain
route serves fine. raw_path is informational and Starlette routes on scope["path"], so the
mutation is simply gone — and leaving raw_path as the client sent it is more truthful for
logs anyway.

TESTS. tests/js/plugin_module_rollback.test.js (5) + 8 in test_plugin_src_route.py:
identical bytes under the prefix, the whole graph one and two levels deep, ASSETS (the
Codex [P2]), every plugin route, non-ASCII filenames (the [P3]), an opaque token, and
containment asserted as PARITY with the un-prefixed route rather than a guessed 404 —
`../screen.js` legitimately 200s on both, because the URL normalises before routing.
All bite-tested: reverting the fix fails the rollback tests, disabling the rewrite fails
the asset tests.

Two harnesses re-anchored on `script.src = _pluginScriptUrl(` — the URL literal they keyed
on now lives in the helper, further down the file, so their slice ran off the end.

refactor(app): carve the library out of app.js (R3a) (#896)
static/js/library.js (1,988) + static/js/library-state.js (29) — bodies VERBATIM.
app.js 6,313 -> 4,451.

THE BIGGEST SLICE OF THE CARVE: 145 declarations, ~1,900 lines, 30% of what was left.
The grid, the artist tree, the A-Z rail, filters, pagination, selection, favourites, the
scan banner, and the library-provider plumbing.

A LOW module: it imports only leaves (./dom.js, ./format.js, ./library-state.js,
./tuning-display.js — all four import nothing themselves) and needs ZERO host hooks. It
calls nothing in app.js. That is not luck; it is why this cluster was picked. Two entry
points that WOULD have dragged the playback core in were left behind in app.js:

  * syncLibrarySong     reaches showScreen/playSong
  * _handleLibArrowNav  Enter on a selected row plays the song

Both are one hop from the library, and app.js is the root, so it imports from both sides
for free. Pulling them in swallows playSong, showScreen and the whole remaining core — I
measured it: the closure jumps from 145 declarations to 189.

library-state.js holds exactly FIVE fields. An imported binding is read-only, and of the
library's outward bindings only these five are genuinely WRITTEN from outside — by
showScreen, deleteSongFromModal and syncLibrarySong, none of which can move in. The other
23 are read-only from outside, so they stay plain exports (ES live bindings mean app.js
still sees every reassignment).

━━━ THE EXPORT LIST NEARLY SHIPPED A DEAD A-Z RAIL ━━━

59 exports — and 43 of them CANNOT be found by a call-graph scan. They are referenced only
from app.js's TOP-LEVEL statements: the Object.assign(window, {...}) contract and the
scattered window.X = X lines, which live outside every function, so a closure walk over
declarations never sees them. Among them are the four handler names app.js composes AT
RUNTIME into onclick="" strings — filterTreeLetter, filterFavTreeLetter, goTreePage,
goFavTreePage — the library A-Z rail and its pagination. No static tool can see those at
all. Had I trusted the call-graph, the rail would have died silently on click with nothing
failing in CI.

━━━ AND MY OWN SCANNER LIED ━━━

The cycle-risk pass reported "(none)" for this carve. It was wrong, and it could not have
been right: a dangling `else if` bound to an inner `if` instead of the outer chain, so its
`imported` map was ALWAYS empty and the check reported clean no matter what. A guard that
cannot fail is worse than no guard. Fixed, and it then found the real edges — dom.js,
format.js, tuning-display.js, library-state.js. All four are leaves, so the carve is
genuinely acyclic; I just now know it instead of assuming it.

(The AST rewriter had its own trap: `MAP[name]` with an object literal and name ===
'constructor' hits Object.prototype.constructor — truthy — and it happily rewrote
`constructor(id)` into `L.function Object() { [native code] }(id)`. Every identifier in
the file is looked up, so the lookup must not see the prototype chain. It is a Map now.)

TESTS. legacy_shim_hits SPLIT (loadLibraryProviders + setLibraryProvider -> the module;
syncLibrarySong stayed in app.js). v3_library_refresh now reads app.js AND the module,
rather than being re-pinned to whichever file happens to hold the emit this week.

VERIFIED. A/B against origin/main in two browsers: the whole window contract, cards render,
grid/tree/sort/filter/clear round-trip — and, specifically, the A-Z rail: 28 onclick
handlers composed at runtime, identical on both, and a real .click() on a letter works.
IDENTICAL on all 33 + 7 probes, no new page errors.

refactor(app): give formatTime a home — a leaf format.js, one fewer host hook (R3a) (#895)
static/js/format.js (17). One function. Retires the formatTime hook: 12 -> 11.

WHY A MODULE FOR ONE FUNCTION. formatTime was a host hook — loops.js and
section-practice.js both reached back through the seam for it. It is ALSO, by pure
accident of who calls it, inside the dependency closure of the library carve that comes
next. Leaving it there would have made loops.js and section-practice.js import the
LIBRARY in order to format a timestamp — nonsense, and a cycle waiting to happen.

Same rule as the transport carve: a hook is a cycle you agreed to live with; an import is
a dependency you actually have. formatTime has a real owner. It just isn't app.js, and it
certainly isn't the library. Give it a home and both consumers import it directly.

A leaf on purpose. Anything else that turns out to be a shared pure formatter belongs
here too; nothing does yet (I checked — formatBadge, _safeImageUrl and _fetchJsonOrThrow
have no callers outside the library), so nothing else is here.

refactor(app): carve the playback transport out of app.js — and RETIRE 8 host hooks (R3a) (#894)
static/js/transport.js (377) — bodies VERBATIM. app.js 6,643 → 6,316.

THIS IS THE FIRST CARVE THAT SUBTRACTS HOOKS INSTEAD OF ADDING THEM.

Every carve before this one added host hooks: a module pulled out of app.js still had
to call back into it. But four modules were all reaching through the seam for the SAME
handful of names — _audioSeek, _audioTime, setPlayButtonState, _songEventPayload,
jucePlayer. Those names have an owner, and it isn't app.js. Give them one, and the
consumers import them directly:

    count-in.js           5 hooks -> 0     (host import deleted)
    juce-audio.js         4 hooks -> 0     (host import deleted)
    loops.js              6 hooks -> 4
    section-practice.js  10 hooks -> 7
    ----------------------------------------------------------
    configureHost()      20 hooks -> 12

A hook is a cycle you agreed to live with. An import is a dependency you actually have.
Prefer the import whenever the name has a real owner.

_audioSeekGen now stays PRIVATE. It has exactly one writer — _resetAudioSeekState(),
which moved with it — so readers get audioSeekGen() and nobody outside can desync it.
Strictly better than the hook it replaces, which handed out a getter and left the writer
behind in app.js.

THE SCAN HAD A HOLE, AND IT BIT. Picking the carve by dependency closure over app.js's
own top-level decls said this cluster was downward-closed. It wasn't:
_currentPlaybackSnapshot reads loopA/loopB — which live in ./js/loops.js, and loops.js
imports transport. The scan saw nothing, because loopA STOPPED BEING an app.js decl the
moment loops.js was carved out. Any dependency scan of a partly-carved monolith has to
resolve the imports too, or it will confidently hand you a cycle. Added that pass; it
found exactly one back-edge, and _currentPlaybackSnapshot stays in app.js (as does
restartCurrentSong, which calls _cancelCountIn). app.js is the root — it imports both
sides for free.

TESTS. Four harnesses retargeted (play_button_reroute_guard, song_event_payload,
song_seek -> transport.js; playback_app_adapter SPLIT, since
_installPlaybackTransportAdapter stayed behind).

The two CENSUS tests — "≥8 song:* emit sites", "every seek callsite passes a reason" —
now scan app.js AND every static/js/*.js, not one file. Pointed at a single file, their
count silently shrinks as code leaves, which reads as "someone deleted an emit" or, worse,
passes while genuinely missing sites. Both bite-tested: stripping a _songEventPayload()
from an emit and adding a reason-less _audioSeek() each fail the suite.

VERIFIED. A/B against origin/main, real song, real playback: song:play payload is exactly
{audioT, chartT, perfNow, time}; song:seek carries reason "seek-by" with finite from/to;
all five song:* events fire; seekBy advances the clock; restartCurrentSong returns to zero;
the play button's aria-pressed tracks state. IDENTICAL on all 21 probes, zero page errors.

refactor(app): carve the JUCE/desktop audio shims out of app.js (R3a) (#893)
* refactor(app): carve resume-session out of app.js (R3a)

static/js/resume-session.js (157) — the snapshot taken when you leave a song and the
pill that offers it back. Bodies VERBATIM. app.js 7,727 → 7,601.
Fifth slice out of the strongly-connected core. ONE hook (playSong) + a
currentFilename getter.

S.pendingResume JOINS THE CONTAINER — on demand, exactly as intended. app.js WRITES
it (playSong({ resume }) arms it; the song:ready listener consumes it) while this
module reads it, so it cannot be a plain export: an imported binding is read-only.
Same reason isPlaying is there. The container grows one field per carve that needs
it, never speculatively.

THE CONTRACT TEST CAUGHT THE MISSING HOOK, again on a path nothing executes:
"playSong is read by a module but never wired by app.js — it would throw at runtime".
Second time it has caught a real wiring gap the moment it appeared.

A REAL TRAP, worth remembering: I first did the S.pendingResume rewrite by feeding
acorn's identifier RANGES from node into python, and it corrupted the file
(`_pS.pendingResume null;`). **Acorn's offsets are UTF-16 code units; Python's string
indices are code points.** static/app.js contains emoji, so every offset past one
drifts. Do an AST-driven rewrite in the SAME language that produced the offsets.
`node --check` caught it; a silent version of that bug is very easy to imagine.

VERIFIED. A/B against origin/main in two browsers, real song: the window API
(resumeLastSession / _snapshotResumeSession / _readResumeSession /
_clearResumeSession), snapshot, read-back, and clear — IDENTICAL, zero page errors.
HONEST LIMIT: my probe never got the snapshot to actually PERSIST (there is a guard
beyond the 3s minimum position that a scripted playSong does not satisfy), so that
path is verified only as identical-to-main, not as observed-working. The real
coverage is tests/browser/resume-session.spec.ts, which drives the flow properly.

Zero harnesses broke. pytest 2396, node 1040/1040, ESLint 0 (no-cycle clean),

* refactor(app): carve the JUCE/desktop audio shims out of app.js (R3a)

static/js/juce-audio.js (994) — bodies VERBATIM. app.js 7,603 → 6,643.
THE LARGEST SINGLE SLICE of the whole carve phase: 960 lines, ~13% of what was left.

Three self-installing IIFEs:
  _installJuceEngineRoutingWatcher (444)  routes a song to the JUCE engine or HTML5 as
                                          the desktop output enters/leaves exclusive/ASIO
  _installRendererBusFeeder        (337)  feeds the highway renderer bus from whichever
                                          transport is actually running
  _installJuceAudioElementShim     (156)  patches audio.play/pause so the rest of the app
                                          keeps talking to the <audio> element while JUCE
                                          owns the transport

They EXPORT NOTHING — all three publish through `window.*` (_juceMode,
_reevaluateJuceRouting, _reevaluateRendererBus, …). So app.js needs only a
side-effect import plus the one binding it actually uses
(_resetJuceAudioShimChain, which the shim IIFE assigns).

THE ORDERING QUESTION, CHECKED RATHER THAN ASSUMED. Importing this module runs the
IIFEs EARLIER than before: imports evaluate ahead of app.js's body, and therefore
ahead of configureHost(). A hook read at IIFE-execution time would THROW. So I walked
the AST at IIFE-body depth to see what they actually touch when they run: nothing but
listener registration, and `audio.play`/`audio.pause` patching — and `audio` is itself
an imported module now. Verified in the browser: both are patched on the carved build
exactly as on main, which proves the shim installs correctly at its new, earlier point.
(Had I got this wrong, host.js throws loudly rather than silently misbehaving — which
is the whole reason it has no no-op defaults.)

VERIFIED. A/B against origin/main in two browsers: the entire window.* surface the
IIFEs publish (_juceMode, _juceOutputIsExclusive, _reevaluateJuceRouting,
_reevaluateRendererBus, _clearJuceRerouteMemo), audio.play/pause patched, a real song
loading and togglePlay driving the public mirror — IDENTICAL, zero page errors.

Harnesses: juce_engine_reroute (19 tests) + renderer_bus_feeder (13) slice the IIFEs by
signature — retargeted, and each sandbox gains a `host` object routed at its EXISTING
stubs so every assertion holds unchanged. test_plugin_runtime_idempotence is SPLIT: 3 of
its 4 source-asserts stayed in app.js, the sm.emit('song:resume') one moved.

refactor(app): carve the player controls out of app.js (R3a) (#891)
static/js/player-controls.js (229) — the speed + mastery sliders and the four
playback-preference reads (autoplay-exit, up-next, countdown-before-song,
confirm-exit). Bodies VERBATIM. app.js 7,914 → 7,727.

The fourth slice out of the strongly-connected core, and by far the easiest: ONE
hook (handleSliderInput) and NO shared mutable state. The three groups are the same
surface — the controls under the highway — and the preference reads are the
one-line localStorage lookups half of app.js consults before deciding whether to
auto-start, show the Up Next pill, run a count-in, or confirm on exit. They travel
with the controls that set them.

Zero missed members on the first build (the no-undef pass was clean), which is the
first time that has happened in this phase.

TWO HARNESSES ARE SPLIT, and both taught something:

  * speed_reset spans BOTH files — playSong (app.js) resets the speed controls
    (module). Its presence GUARDS still read `src.includes('function setSpeed')`
    against app.js, so once the code moved they silently evaluated FALSE and the
    helpers were quietly dropped from the sandbox. A guard that disables itself is
    worse than no guard. Repointed at the file the code actually lives in.

  * Its `host.handleSliderInput` stub had to route at the sandbox's EXISTING spy,
    not a fresh `() => {}`. The test asserts the slider was actually refreshed
    (`deepEqual(__sliderInputs, ['speed-slider'])`); a fresh stub swallows the call
    and the assertion passes VACUOUSLY. Same failure mode as a no-op host default —
    the thing this whole seam design exists to prevent.

  * autoplay_exit is split too: _autoplayExitEnabled moved, but the auto-exit
    machinery around it (_clearAutoExit, holdAutoExit, _resolvePlayerOrigin) stayed.

VERIFIED. A/B against origin/main in two browsers, real song: setSpeed(0.75) ->
playbackRate 0.75; applySpeedPreset(100) -> 1; the speed slider; setMastery;
setAutoplayExit / setCountdownBeforeSong / setShowUpNext — IDENTICAL, zero page errors.

refactor(app): carve count-in (and the song-credits overlay) out of app.js (R3a) (#890)
static/js/count-in.js (389) — bodies VERBATIM. app.js 8,223 → 7,913.
The third slice out of the strongly-connected core, and the first that WRITES
shared state rather than only reading it. #889's container is what makes it possible.

  imports: loops (setLoop/loopA/loopB — a count-in inside an A-B loop must begin at
           A), audio-el, player-state, host
  hooks  : _audioSeek, setPlayButtonState, _songEventPayload, togglePlay + a
           jucePlayer getter
  Nothing imports count-in back — app.js and section-practice both reach it through
  the seam — so the graph stays acyclic.

app.js's autoplay path used to reach IN and set this module's credits timers itself
(_creditsTimer, _creditsHideOnPlay) and read _countingIn. It cannot now, and should
not have to, so the module exports the OPERATIONS instead — armCreditsHideOnPlay(),
scheduleCreditsHide(), holdCreditsThen(start), isCountingIn() — and owns its own
timer invariants. Third time this has happened (section-practice's resetSelection,
loops' state) and each time the constraint produced better code than was there
before: the module keeps its own promises instead of trusting a caller 6,000 lines
away to zero the right fields.

THE no-undef GATE FOUND FIVE MISSED MEMBERS, one at a time: showSongCreditsOverlay
and startSongCountIn (my name regex matched startCountIn, not startSongCountIn),
then _creditLineLabel, _CREDITS_MAX_MS, and _CREDIT_ROLE_VERBS. A call-graph closure
does not see a const table; only the undefined-symbol pass does.

AND A REAL TRAP: I computed _CREDIT_ROLE_VERBS's span against the ALREADY-MODIFIED
app.js and applied it to the clean one — the line numbers had drifted, so the slice
would have cut somewhere else entirely. Recomputed every span from the clean file
with acorn. Never carry line numbers across an edit.

VERIFIED. A/B against origin/main in two browsers with a real song: playback state,
the public feedBack.isPlaying mirror, audio position, cancel-count-in — IDENTICAL,
zero page errors. Unit coverage moved with the code: loop_restart's count-in
cancellation-token test and the 5 song_credits_overlay tests now read count-in.js;
loop_restart's sandbox gains a `host` object routed at its EXISTING stubs, so every
assertion is unchanged.

HONEST LIMIT: I could not make the count-in OVERLAY actually render headlessly —
its autoplay path needs a fresh-load _pendingAutostart that a scripted playSong()
never arms. Behaviour is identical to main on every probe and the unit tests cover
the logic, but the on-screen 1-2-3-4 and the credits card want a human look.

refactor(app): lift the shared player state onto a container (R3a) (#889)
static/js/player-state.js — one exported object, two fields. app.js's 70 reference
sites rewritten. Provably a no-op; nothing shrinks.

WHY NOW. Every slice carved out of app.js so far only ever READ the state it shared
(loopA/loopB, _audioSeekGen, currentFilename), so a read-only getter hook was enough
and no container was needed — twice I checked and twice I got away with it. That
runs out at count-in: it genuinely WRITES `isPlaying` (it starts and stops playback,
4 sites) and `lastAudioTime` (2). `import { isPlaying }` then `isPlaying = true`
THROWS — an imported binding cannot be assigned to. So the state has to live on an
object: `S.isPlaying = true` is a property write, and works from any module holding
the same S. Same shape stems, studio, and editor all converged on.

DELIBERATELY SMALL. app.js has ~104 top-level `let` scalars; lifting all of them is
a ~977-site rewrite for no benefit, because most are private to one cluster and
travel with it. Only what a carved module must WRITE goes here. Add on demand.

THE REWRITE IS AST-DRIVEN, NOT TEXTUAL — and that is not fussiness. Of 100 textual
occurrences of these two names, only 70 resolve to the module binding:
  * 22 are member accesses (`someObj.isPlaying`, `window.feedBack.isPlaying`)
  * 4 are the LOCAL PARAMETER of `function setPlayButtonState(isPlaying)` — a blind
    replace yields `function setPlayButtonState(S.isPlaying)`
  * 1 is an object key
  * 2 are shorthand properties `{ isPlaying }`, which must become
    `{ isPlaying: S.isPlaying }` — and acorn gives a shorthand's key and value the
    SAME range, so rewriting both produced `isPlaying: S.isPlaying: S.isPlaying`
    until I deduped by range
A find-and-replace corrupts all 29. The rewrite walks the AST, skips shadows, member
properties and keys, and replaces identifier RANGES.

`window.feedBack.isPlaying` — the PUBLIC mirror — is a different thing and is
untouched. Two test sandboxes stub it; those were left alone deliberately.

VERIFIED WITH REAL PLAYBACK. A/B against origin/main in two browsers, real song:
togglePlay -> the public mirror goes true -> false -> true across two toggles, the
audio element's paused state follows, seekBy works — IDENTICAL, zero page errors.

Harnesses: 8 vm-sandbox suites slice playback code out of app.js and now see
S.isPlaying — juce_engine_reroute, loop_restart, play_button_reroute_guard,
playback_app_adapter, song_restart, song_seek, speed_reset, and the python
idempotence source-assert. Each gets the same container in its sandbox; every
assertion is unchanged.

refactor(app): carve the A–B loop out of app.js (R3a) (#888)
static/js/loops.js (261) — bodies VERBATIM. app.js 8,421 → 8,224.
The second slice out of the strongly-connected core.

It OWNS the loop state — loopA, loopB, _loopMutationGen. Nothing outside writes
them: restartCurrentSong() looked like it did, but it declares its own local `let
loopA/loopB` shadows, so the module-level bindings only ever change in setLoop /
setLoopStart / setLoopEnd / clearLoop. All four move here. No state container.

DIRECTION IS THE WHOLE DESIGN. loops and section-practice are mutually dependent —
the SCC in miniature. clearLoop() must drop section-practice's selection, and
practiceSection() must call setLoop(). Both edges cannot be imports or no-cycle
(rightly) rejects it. So:

    section-practice  ->  reaches loops through the HOST SEAM (host.setLoop, …)
    loops             ->  imports section-practice DIRECTLY

section-practice is the higher-level feature — a consumer of loops, not the reverse
— so it is the one that takes the indirection. app.js hands the loop module's
exports across into the seam for it. Graph stays acyclic; no-cycle passes.

THE CONTRACT TEST EARNED ITS KEEP IMMEDIATELY. It failed on the first build with
"these hooks are wired by app.js but no module reads them: playSong". My dependency
scan had counted a mention of playSong() inside a COMMENT in loops.js as a real
call. Wired but unused is precisely the "fossil of a rename" case the test exists
for — and it caught it on a path no test executes.

VERIFIED BY DRIVING BOTH SIDES OF THE SEAM. A/B against origin/main in two browsers,
real song loaded:
  * setLoop(5,12) -> true; getLoop() -> 5,12 — IDENTICAL
  * clearLoop() (loops -> section-practice, a direct import) -> getLoop() ->
    null,null — IDENTICAL
  * onPhraseNext() (section-practice -> loops, ACROSS THE SEAM) -> ok — IDENTICAL
  * loadSavedLoop / saveCurrentLoop / deleteSelectedLoop on window — IDENTICAL
  * zero page errors either side. An unwired hook throws, so a live app is itself
    proof the seam is wired.

Harness: loop_api extracts the loop helpers by signature — retargeted to loops.js,
`export` stripped for the vm sandbox, and the sandbox's existing _audioSeek /
_audioTime / formatTime spies are now routed through a `host` object so every
assertion holds unchanged, just through the indirection the real code uses. It is
SPLIT: one test still reads app.js for the window.feedBack API surface, which stayed.

refactor(app): the host seam + carve section practice out of app.js (R3a) (#887)
static/js/host.js (99) + static/js/section-practice.js (1,214).
app.js 9,461 → 8,409.

THE FIRST SLICE OUT OF THE STRONGLY-CONNECTED CORE. What is left in app.js is not
a tree, it is a cycle: seeding a dependency closure from section-practice, from
loops, from count-in, or from the JUCE seek shim all return the SAME 178-function
set, and setLoop() and practiceSection() call each other directly. No closure-based
carve can cut it at any seed. So it is cut BY NAME, and the calls back into app.js
go through a host seam.

  61 functions + its own 24 _sectionPractice*/_sectionParents* scalars (read nowhere
  else) move out. 11 hooks come back in. 4 of those are read-only GETTERS —
  loopA/loopB/_audioSeekGen/_loopMutationGen are only ever READ here, never written,
  so app.js keeps owning them and NO state container is needed (a 977-site lift
  avoided).

app.js used to reach IN and reset the module's state by hand (clearLoop() zeroed the
selection; changeArrangement() invalidated the parent count). It cannot now — an
imported binding is read-only — so those are exported as resetSelection() and
invalidateParentCount(). Strictly better: the module owns its own invariants instead
of trusting two callers on the far side of the file to zero the right three fields.

═══ THE SILENT-NO-OP PROBLEM, SOLVED ═══
The obvious host seam is an object of no-op defaults. That is a TRAP and we walked
into it once: the plugin loader's seam defaulted populateVizPicker to `() => {}`, so
a dropped wiring line would have left the viz picker quietly not refreshing with NO
test, boot check, or bot noticing. Two layers stop it here:

  1. RUNTIME — host.js is a Proxy with NO defaults and NO stubs. Reading an unwired
     hook THROWS. An unwired hook cannot degrade into a no-op because there is
     nothing to degrade INTO. configureHost() also rejects a non-function at WIRE
     time, and refuses to run twice.

  2. STATIC — tests/js/host_contract.test.js asserts the hooks the modules USE are
     exactly the hooks app.js WIRES. This is the layer that matters: a runtime throw
     only fires if the broken path executes, and the whole danger of a seam is the
     paths that never run in a smoke test. VERIFIED TO BITE in all three drift
     directions: drop a hook from configureHost -> fails; rename host.setLoop in the
     module -> fails; wire a hook nobody uses -> fails.

Writing that guard took three tries and each failure is instructive: (a) the
configureHost regex anchored `});` at column 0, ran past the indented close, and
swallowed app.js's 66-name window contract — 77 "hooks"; (b) an import-stripping
regex with `[\s\S]*?` ate 14,000 characters INCLUDING the drift the bite test was
meant to catch — a guard with a hole is worse than no guard, because you trust it;
(c) `host.js'` in the import path backtracked from `js` to a "hook" called `j`.
The bite tests are what surfaced all three.

CODEX FOUND A REAL RACE [P2]. configureHost() was inside the async boot function,
after several awaits — but the window handlers (onPhraseNext, …) go live during
app.js's SYNCHRONOUS module evaluation. A user clicking one in that window would hit
"[host] … was read before configureHost() ran". It is now a bare top-level statement
sitting immediately before the window contract, so the seam is always wired before a
handler can be reached. Verified live: invoking a handler 1.2s in — well before the
boot awaits settle — works.

VERIFIED. A/B against origin/main in two browsers with a REAL song loaded: popover
toggle, practice-mode change, phrase-next, and clearLoop (all of which cross the seam
— setLoop/clearLoop/_audioTime/loopA/loopB) — IDENTICAL, zero page errors. Since an
unwired hook throws, a live app is itself proof the seam is wired.

Harnesses: section_practice_dismiss retargeted; loop_api's clearLoop sandbox gains a
resetSelection SPY (not a stub) and ASSERTS it fires — the guarantee is still tested,
just through the seam.

refactor(app): give the <audio> element a module of its own (R3a) (#886)
static/js/audio-el.js — one exported const. app.js's diff is 5 lines.
This is a HINGE, not a carve: nothing shrinks, but almost everything left in
app.js is blocked behind it.

WHY. `audio` is `document.getElementById('audio')` with 162 references in app.js
and 173 outside any one cluster. Every remaining cluster measured — settings,
app-updates, count-in (208 fns), exit-confirm (212), library-render (220) — lists
`audio` among its inbound symbols, because they all touch playback and playback
reaches for the element directly. A module that needs it cannot import app.js to
get it (that closes a cycle and fails import-x/no-cycle), so today the only way to
carve any of them would be a host seam — the exact thing #878 had to build and
#880 had to tear out.

WHY IT'S SAFE. `audio` is a `const` and is NEVER reassigned anywhere in core, so a
read-only import binding is exactly right and no state container is needed. The
162 call sites are untouched — the binding keeps its name, it is just imported
instead of declared. (Contrast the reassigned scalars — isPlaying, _avOffsetMs —
which CANNOT be shared this way: an imported binding cannot be written to. Those
still need containers, and that is the next problem, not this one.)

TIMING. app.js is <script type="module">, so it evaluates after the HTML is parsed
and its imports evaluate just before its body — the same moment app.js used to run
this exact lookup. If the element had not been in the document, `audio` would be
null and app.js's top-level `audio.addEventListener(...)` calls would throw and
kill the module. They don't.

VERIFIED WITH REAL PLAYBACK, not a boot check. A/B against origin/main in two
browsers: app alive with zero page errors (which is itself the proof the import
resolved), #audio is an AUDIO element, togglePlay/seekBy live, and playSong() on a
real library song sets audio.src and the element reports a duration — IDENTICAL on
both sides.

refactor(app): carve settings backup + plugin updates out of app.js (R3a) (#885)
Two leaves, one PR. app.js 9,651 → 9,457.

static/js/settings-io.js (155) — exportSettings + importSettings, the Settings
backup bundle. Imports nothing. The two-phase rationale comment (server first and
atomic; then a best-effort localStorage merge) is the contract and moved with the
code.

plugin-updates → INTO static/js/plugin-loader.js, not a module of its own.
checkPluginUpdates + updatePlugin are plugin MANAGEMENT; they belong with the code
that loads plugins. A new file for 50 lines would have been a file for its own
sake.

All four are inline handlers on the Settings screen and already in app.js's window
contract, so app.js re-exposes the imported bindings unchanged.

VERIFIED BY DRIVING BOTH FLOWS. A/B against origin/main in two browsers:
  * checkPluginUpdates() -> hits the API and settles the button back to
    "Check for Updates" — IDENTICAL
  * exportSettings() -> POSTs /api/settings/export and writes
    "Exported feedBack-settings…" to #backup-status — IDENTICAL (fetch intercepted
    so the assertion is on the real call, not a stub)
  * all four resolve on window — IDENTICAL
  * zero console/page errors either side

Zero harnesses broke. pytest 2396, node 1038/1038, ESLint 0, tailwind clean, Codex 0.

refactor(app): carve the tuning-display helpers out of app.js (R3a) (#884)
static/js/tuning-display.js (228 lines) — bodies VERBATIM. app.js 9,838 → 9,650.
A LEAF: imports nothing.

Tuning NAME resolution (Drop D / Eb Standard / raw-offset fallback), bass
detection, effective string count, and the target FREQUENCIES + note names the
tuner checks against. Pure functions over a small MIDI/note-name table; the 3
_TUNING_* tables are read nowhere else and move in.

NOT A SLICE — a node-level extract. The span 2309-2535 INTERLEAVES the functions
with the `window.*` / `window.feedBack.*` assignments that publish them, and one
of those is `window.feedBack = window.feedBack || {}` — the BUS BOOTSTRAP, not
tuning code at all. Every ExpressionStatement stays exactly where it was; only the
16 functions and 3 tables move. app.js re-exposes the imported bindings from the
same lines, so the public surface and its ordering are untouched (constitution II
names window.feedBack).

  app.js -> { plugin-loader, viz, diagnostics-export, dom, highway-colors,
              tuning-display }

HARNESSES — 4 broke, and 3 of them broke in the SAME informative way: they sliced
app.js from `function isBassArrangement(` UP TO the marker
`window.feedBack.parseRawTuningOffsets = parseRawTuningOffsets;` — an end-marker
that (correctly) stayed behind in app.js. The module is now nothing BUT the tuning
helpers, so there is no block to slice: they read it whole and strip `export ` so
the vm sandbox still evaluates it as a script.
  tuner_auto_open is SPLIT — its autoplay-gate test still reads app.js, so it keeps
  APP_JS and gains TUNING_JS. Retargeting its path wholesale (my first attempt)
  silently pointed the autoplay test at the wrong file.

VERIFIED BY DRIVING THE CONTRACT. A/B against origin/main in two browsers, through
the real window surface: displayTuningName -> "E Standard" / "Drop D" /
"Eb Standard", parseRawTuningOffsets('-2,0,0,0,0,0') -> [-2,0,0,0,0,0],
isBassArrangement, effectiveStringCount, displayTuningTargets, and
window.feedBack.displayTuningName / .songTuningContext — IDENTICAL on both, zero
console/page errors either side.

refactor(app): carve the highway string-colours out of app.js (R3a) (#883)
static/js/highway-colors.js (601 lines) — bodies VERBATIM.
app.js 10,415 → 9,837. Under 10k.

DECOMPOSED, not sliced. The "settings" blob measured 47 fns / 19 inbound and was
not carvable as-is. Seeding the closure from a FUNCTION (initHighwayColors) found
only 18 fns and left 4 HWC_* constants used outside it — i.e. the seed was wrong,
not the cluster. Re-seeding from the STATE (every function touching HWC_*/`_hwc*`)
found the true cluster: 45 top-level nodes, lines 2751-3331, CONTIGUOUS, with ZERO
foreign nodes inside the span.

  INBOUND: 0.  EXPORTS: 2 (initHighwayColors, hwcInitSettingsUI).

The other 43 symbols — the HWC_* tables, the 12 presets, the theme store, the
share codec, the picker handlers, the window.feedBack.highwayColors facade — are
used nowhere else in core and stay private. No inline on*= handlers here (the
Settings buttons are wired by addEventListener inside hwcInitSettingsUI), so
nothing needed re-exposing on window. The three bus listeners register inside
initHighwayColors, which app.js calls — not at module top level — so no ordering
change.

THE no-undef GATE EARNED ITS KEEP. My closure said INBOUND=0; the module actually
uses `uiPrompt` (the "name this theme" prompt). It was missed because uiPrompt is
no longer an app.js DECLARATION — it's an IMPORT BINDING (from #882's dom.js), and
I was collecting declarations only. `no-undef` with typeof:true caught it.
  => Lesson for the next carve: seed `tops` from ImportDeclaration bindings too.
  => And it VALIDATES carving dom.js early: this module just imports uiPrompt from
     it. Had dom.js still been stranded in app.js, this carve would have needed a
     host seam.

  app.js -> { plugin-loader, viz, diagnostics-export, dom, highway-colors }
  plugin-loader -> viz
  highway-colors -> dom
  viz, diagnostics-export, dom -> (leaves)

VERIFIED BY DRIVING THE FACADE. A/B against origin/main in two browsers:
window.feedBack.highwayColors installed, identical method surface, 12 presets,
identical default slot colours, and a share-code encode→decode round-trip
returning #112233 — IDENTICAL on both, zero console/page errors either side.

Harnesses: highway_colors_facade + highway_string_colors retargeted (both
brace-extract blocks out of the source by signature).

refactor(app): carve the DOM/modal primitives out of app.js (R3a) (#882)
static/js/dom.js (203 lines) — esc, _escAttr, _isElementVisible, _trapFocusInModal,
_confirmDialog, uiPrompt. Bodies VERBATIM. app.js 10,593 → 10,414.

A GATHER, not a slice — the six lived in six different places (108, 635, 659,
2617, 2623, 8892). They belong together because they are the BOTTOM of the UI
stack: `esc` alone has 25 call sites and `_escAttr` 23, and every later carve that
renders HTML will need them.

That is the actual point of doing this one now. Give them a home and the next
carve imports them; leave them in app.js and the next carve that renders HTML has
to invent a host seam to reach back into app.js — exactly the trap the
plugin-loader carve had to work around until the viz layer became a module. This
is the cheapest possible way to stop that recurring.

  app.js -> { plugin-loader, viz, diagnostics-export, dom }
  plugin-loader -> viz
  viz, diagnostics-export, dom -> (nothing)

Zero imports. Six exports (every one is used outside the cluster).

VERIFIED BY DRIVING THE MODALS, not just booting — they are interactive, so a
green suite says little. A/B against origin/main in two browsers:
  * window.uiPrompt / _confirmDialog / _trapFocusInModal all resolve
  * uiPrompt() mounts its modal, accepts typed input, and resolves with the typed
    value ('typed') — IDENTICAL on both
  * _confirmDialog() mounts and resolves true on confirm — IDENTICAL
  * zero console/page errors either side

refactor(app): carve the diagnostics-bundle export out of app.js (R3a) (#881)
static/js/diagnostics-export.js (280 lines) — bodies VERBATIM.
app.js 10,858 → 10,592.

Chosen BY MEASUREMENT, not by eye. Ran the transitive closure over four candidate
clusters and took the one with the smallest interface:

  diagnostics       7 fns   235 lines  span 4110-4378  imports 1  exports 2
  shortcuts-modal   5 fns   235 lines  span  104-9897  imports 4  exports 5
  settings+updates 47 fns  1012 lines  span 1409-7636  imports 19 exports 30
  library-render  220 fns  4064 lines  span   20-10536 imports 126 exports 117

diagnostics is contiguous and nearly closed; its one inbound symbol
(_DIAG_FILE_LABELS) lives inside the region and is read only by _renderDiagPreview,
so it moves in and the module ends up a LEAF — imports nothing.

  app.js -> { plugin-loader, viz, diagnostics-export }
  plugin-loader -> viz
  viz, diagnostics-export -> (nothing)

Exports exactly 2: previewDiagnostics + exportDiagnostics, both already in app.js's
window contract (they're inline handlers in the Settings screen) — so app.js keeps
re-exposing them, now as imported bindings. The preview renderer, the file-label
table, and the byte/HTML formatters are used NOWHERE else in core and stay private.

VERIFIED BY DRIVING IT, not just booting. Zero harnesses broke — because the
diagnostics export flow had NO source-level test at all, which is exactly why a
green suite proves nothing here. So the flow was exercised for real: A/B against
origin/main in two browsers, window.previewDiagnostics() invoked, the preview
container rendered identical content on both, both entry points resolve on window,
zero console/page errors either side.

pytest 2396, node 1038/1038, ESLint 0, tailwind-fresh clean, Codex 0.

NOTE for the next carve: library-render is NOT a cluster — 220 functions and 126
inbound symbols is most of app.js entangled together. It cannot be carved as a
unit; it needs decomposing from the inside first.

refactor(app): carve the viz layer out of app.js — and delete the loader seam (R3a) (#880)
static/js/viz.js (770 lines) — the viz picker, renderer selection, Auto-match,
the WebGL2 probe, the 3D-promotion nag, the notation hints. Bodies VERBATIM.
app.js 11,603 → 10,857.

THE SEAM IS GONE. #878's plugin-loader needed configurePluginLoader({
populateVizPicker }) purely because _populateVizPicker lived in app.js and
importing app.js would have closed a cycle. viz.js is a LEAF — it imports NOTHING
— so plugin-loader now imports _populateVizPicker straight from it. The _host
object, the configure function, its loud-default guard, and the wiring line in
app.js are all deleted. The second carve simplifies the first.

  app.js -> { plugin-loader, viz }
  plugin-loader -> viz
  viz -> (nothing)

NOT A PURE MOVE — one listener block had to be SPLIT. app.js had a single
top-level `if (window.feedBack) { … }` registering four handlers, and only two
were viz. song:loaded / arrangement:changed / song:ready (the mastery slider)
stay in app.js and now call the imported _autoMatchViz / _maybeShowNotationViewHint.
The viz:reverted handler MOVES, because it REASSIGNS _cancelPendingAutoLabel and
an imported binding is read-only — `_cancelPendingAutoLabel = null` would throw if
the listener stayed behind while the state moved.

ORDER CHECKED, NOT ASSUMED: viz.js's song:ready listener now registers BEFORE
app.js's own (imports evaluate first). Safe — _pendingPromotionNag is only ever
set inside _populateVizPicker, which runs at boot/plugin-refresh, never from
inside the other song:ready handler, so the two are independent.

VERIFIED — the listeners are the risk here, so they were DRIVEN, not just booted.
A/B against origin/main in two browsers:
  * viz picker: 6 options (auto|default|venue|drum_highway_3d|keys_highway_3d|
    highway_3d), selected highway_3d, Auto label — IDENTICAL. This alone proves
    plugin-loader's direct import of viz.js works.
  * emit('viz:reverted') -> picker resets to default, localStorage resets to
    default, the warning logs — IDENTICAL. The MOVED listener fires.
  * emit('song:ready') -> mastery slider enables, no throw — IDENTICAL. The SPLIT
    listener still does both halves.
  * plugin screens, module injections, 37 capability participants — IDENTICAL.
  * zero console/page errors on both.

pytest 2396, node 1038/1038, ESLint 0, tailwind-fresh clean. no-cycle re-bitten on
the 3-module graph (viz -> plugin-loader fails).

Codex preflight raised a [P2] claiming viz.js's top-level bus guards would be
false because "app.js only creates the event bus later" — FALSE POSITIVE. app.js
does not create the bus; capabilities.js does, from its own <script type="module">
at index.html:122, and module scripts execute in document order, so the bus exists
long before app.js's import graph evaluates. Instrumented the setter: by viz.js's
turn `window.feedBack.on` is already a function, and the viz:reverted listener is
provably attached (firing it resets the picker). The ordering is also enforced by
test_app_shell_loads_capability_registry_before_app_runtime.

Harnesses: 5 tests retargeted to viz.js across legacy_shim_hits, venue_scene_3d,
venue_viz (each SPLIT — their non-viz tests still read app.js).

feat(audio): loopback feeder mode + static no-cache — all app audio under exclusive/ASIO (#877)
* feat(audio): route feedpak full-mix natively under exclusive output

Song playback runs through the renderer, which WASAPI-exclusive (and
ASIO) output silences. Route single-mix feedpaks (stem-less
original_audio packs AND single-stem packs) onto the engine's backing
transport when the output device type is exclusive-style, and migrate
back to HTML5 when it isn't. Extends /api/audio-local-path to resolve
/api/sloppak/.../file/... URLs via the same containment guards as
serve_sloppak_file. Multi-stem packs stay on the WebAudio path
(Phase 2). Includes [feedpak-route] transition-gated diagnostics
logging.

* feat(audio): renderer-bus feeder — mix renderer song audio into engine output (Phase 2)

Under exclusive-style output the native backing transport (Phase 1, #824)
carries loose /audio/ songs and feedpak full-mixes, but not the stems
plugin's multi-stem WebAudio graph or tracks JUCE rejected. The feeder taps
the renderer-side master with an AudioWorklet, re-points the owning
AudioContext at a null sink so it keeps rendering without a device, and
pushes ~10 ms chunks over IPC into the desktop engine's renderer bus
(feedBack-desktop#90 follow-up). Inert in the Docker sphere and in shared
mode. Validated by the fix12 tester spike: null-sink rendering works,
clocks hold, no overflow.

default WASAPI device under ASIO output. Also confirmed: the element
capture path poisons itself when highway_3d already owns #audio's

- New preferred mode 'loopback': one getDisplayMedia frame-audio capture
  (desktop main answers with the app's own frame) covers song, previews,
  and UI sounds for the whole exclusive session — engages even with no
  song loaded. Local playback silenced via suppressLocalAudioPlayback,
  page-mute IPC fallback otherwise.
- Sticky fallback to the existing stems/element surface modes when
  capture is unavailable (old desktop main, denied, Docker sphere).
- Element capture: assign module state only after the whole chain
  succeeds; close the context on failure — collision now retries clean.
- Failed engage now disables the bus and tears down loopback (no more
  bus-enabled-with-no-producer stranding).
- Tests: 12 (5 new — loopback engage/preference/mute-fallback/sticky

The loopback context was reused across engages (_lbCtx || new), but teardown
only stopped the stream + deactivated the tap — never closing the context or
detaching the worklet node. Each exclusive<->shared switch orphaned a live
tap worklet on the long-lived context. Use a fresh context per session and
close it on disengage. Adds a test asserting the context is closed on teardown.

* feat(diag): install-time + uncaught-error diagnostics for the reroute chain

2026-07-11 tester log showed the routing watcher and renderer-bus feeder
never installed (zero [feedpak-route]/[renderer-bus] lines) plus an
uncaught SyntaxError with no source location — nothing in the log said
why. New:

- global error/unhandledrejection tap logging message + filename:line:col
  (error events carry the location even for parse errors in other scripts)
- explicit install / NOT-installed lines for watcher and feeder (incl.
  loopback capability probe)
- DOMException detail (name/message/stack head) in the feeder retry warn
  — the console-message forward stringified it to [object DOMException]

* fix(static): force conditional revalidation on /static (Cache-Control: no-cache)

Without Cache-Control Chromium's heuristic freshness (10% of file age)
serves /static/app.js from disk cache for hours-to-days without
revalidating. Desktop consequence: a new build's window ran the previous
build's app.js — the 2026-07-11 ASIO investigation traced 'routing
watcher never installed' + a stems module-plugin SyntaxError to exactly
this (stale loader predating scriptType support). no-cache keeps caching
but revalidates via ETag — unchanged files still cost only a 304.

* fix(diag): gate install-time + uncaught-error [asio-diag] lines on --debug

The error tap and install lines from the previous diag commit were
unconditional. Now: error/rejection taps check _asioDiagEnabled() at
event time; install lines log deferred once the async debugEnabled()
resolves true. The NOT-installed anomaly lines stay bridge-gated
(window.feedBackDesktop present) instead — a broken bridge can't deliver
the debug flag, they fire at most once, and only in the broken state
they exist to witness. Docker sphere: fully silent.

refactor(app): carve the plugin loader out of app.js into static/js/ (R3a) (#878)
The first carve, and deliberately the riskiest: app.js IS the plugin loader (the
R0 host rails), so it goes first while the module graph is still one edge deep.

static/js/plugin-loader.js (829 lines) — bodies VERBATIM. app.js 12,217 → 11,439.
Core's first `static/js/` module, exactly as constitution II anticipates.

CLOSURE (measured with acorn, not regex — brace-matching stripped source drifted):
the block at app.js:11246-12031 is contiguous and self-contained. It needs only
TWO things from the rest of app.js, and exports only TWO:
  exports: loadPlugins (the window contract), bootstrapPluginsAndUi (boot)
  inbound: window.showScreen — already the public host contract (constitution II),
           so it is called through `window`, not re-coupled as an import
           _populateVizPicker — injected via configurePluginLoader()

WHY A SEAM, NOT AN IMPORT. plugin-loader must not import app.js: app.js imports
it, so that would close a cycle. I checked whether _populateVizPicker could just
move into the module instead (which would delete the seam entirely) — it drags 9
further symbols (_canRun3D, _autoMatchViz, _showPromotionNag, …), i.e. a whole
viz cluster. That is its own carve, so the seam stays.

THE SEAM'S DEFAULT IS LOUD, ON PURPOSE. A no-op stub is the classic silent
failure for this pattern (see the editor's setHostHooks trap, hit twice): drop the
wiring call and the loader keeps working while the viz picker quietly stops
refreshing — no test, no boot check says a word. The default now console.errors,
so the smoke harness catches it. VERIFIED BY BITE TEST: removing
configurePluginLoader() from app.js surfaces
"[plugin-loader] host seam not configured" at boot. The seam IS exercised on the
plugin-startup path, so an unwired hook cannot pass silently.

no-cycle is now LIVE on core's own graph for the first time. eslint.config.js
gains `static/app.js` + `static/js/**` to the module block — app.js now `import`s,
so parsing it as a script would be a syntax error. VERIFIED BY BITE TEST: making
plugin-loader import app.js back fails with "Dependency cycle detected".

HARNESSES (the R3a note said budget one conversion per carve — it was five):
retargeted capability_inspector_nav, plugin_hydration_wipe,
plugin_loader_script_type, plugin_style_injection, legacy_shim_hits (SPLIT — one
test needs the loader, one still needs app.js) + test_plugin_runtime_idempotence.
legacy_shim_hits was missed by a symbol-name grep because it greps for a code
STRING; only the failing run found it. test_capability_events' NEGATIVE asserts
now span app.js + the loader — carving code out of app.js would otherwise make
them vacuous instead of failing.

VERIFIED: A/B against origin/main in two browsers — mounted plugin screens, 14
loaded plugin scripts, the 3 module plugins injected as <script type="module">,
37 capability participants, 14 shims, window.loadPlugins: IDENTICAL, zero
console/page errors on both. /static/js/plugin-loader.js serves 200; R0 rails
intact (src/main.js 200, conditional GET 304, script_type passthrough).
pytest 2396, node 1032/1032, ESLint 0, Codex 0.

Codex preflight caught a REAL [P1] first pass: static/js/plugin-loader.js was
untracked, so a checkout would have served an app.js importing a nonexistent
module — a failed static import kills the whole module and every window handler
with it. Now tracked.

refactor(ui): load app.js as an ES module (R3a) (#876)
One attribute. #871/#872/#874/#875 exist to make this line safe.

app.js's 385 top-level `function` declarations stop being implicit `window`
properties: 87 stay reachable via the explicit contract (#874's Object.assign
block + the 47 pre-existing `window.X = X` assignments), and 298 become
module-private. Verified NO unexposed name is read from outside app.js.

Strict mode (modules are always strict) checked ahead of the flip: app.js parses
clean as `sourceType: module` (no octal, dup params, `with`), and has no implicit
globals, no `eval`/`new Function`, no top-level `this`. `registerShortcut` is
called bare at 15 top-level sites but is assigned at `window.registerShortcut`
(app.js:10387) before its first call (10648), and a bare identifier in a module
still resolves through the global object — verified `typeof
window.registerShortcut === 'function'` in the browser.

HARD GATE — app.js IS the plugin loader:
  - /api/plugins script_type passthrough: editor/stems/studio = "module"
  - /api/plugins/stems/src/main.js -> 200; conditional GET -> 304 (live-edit ETag)
  - deep graph: stems/src/transport.js, editor/src/state.js -> 200
  - window.loadPlugins present; 5 plugin screens mount; the 3 migrated plugins
    injected as <script type="module">
  - 37 capability participants, 14 compatibility shims, bus + capabilities v1

Every one of the shell's 336 inline handlers resolves on window under module
scope, and the A-Z rail / pagination execute 6/6 with no ReferenceError. A/B
against origin/main: the ONLY unresolvable handler is `editorToggleStemMixer`,
which is equally broken on main (a dead handler in the editor plugin — not
defined anywhere in its source; pre-existing, flagged separately).

Codex preflight raised a [P1] claiming restartCurrentSong / requestExitSong /
editRegionInEditor / returnToEditorFromHighway would ReferenceError — FALSE
POSITIVE. It scanned only #874's new Object.assign block and missed app.js's 47
scattered `window.X = X` assignments; all four are at app.js:7086/7204/8492/8511
and all four resolve as `function` in the browser with app.js loaded as a module.

pytest 2396, node 1032/1032, ESLint 0 errors, tailwind-fresh clean.

refactor(ui): load the capabilities as ES modules (R3a) (#875)
Some checks are pending
ship-ci / ci (push) Waiting to run
The 12 capability <script> tags become type="module". No JS changes — the
capability scripts already self-register on the window.feedBack bus,
version-negotiate (`capabilities.version !== 1` → bail), and self-guard for
idempotency. They never import or call app.js; it is pure pub/sub.

Verified they export nothing by name: no top-level declaration in
capabilities.js or capabilities/*.js is read by any other script, so losing
global scope costs nothing.

This is the first REAL exercise of the ordering fix from #872. A module defers to
after HTML parse, so the capabilities now execute AFTER the document is parsed —
while app.js still calls `window.feedBack.on(...)` at its top level. That only
works because #872 put every classic script into the same deferred queue, where
document order IS execution order: capabilities.js (line 122) still runs before
app.js (line 1237). Had app.js stayed a plain classic script it would have run
during parse, hit a bare `{}`, and died on `.on is not a function`.

A/B against origin/main, 11 probes — capabilities.version, registered
participants (37), compatibility shims (14), the bus, workingTuning, theme,
setViz/showScreen/playSong, mounted plugin screens: IDENTICAL, zero console/page
errors on both. 12 module tags served and executed; pytest 2396, node 1032/1032,
ESLint 0, Codex 0.

refactor(app): make app.js's window contract explicit — 66 names (R3a) (#874)
app.js is a classic script, so each of its 385 top-level `function foo()` decls
is implicitly a property of `window`. As an ES module it will not be — module
scope is not global scope — and every name reached from outside this file would
silently vanish. This adds the explicit `window.*` assignments BEFORE the flip.

Provably a NO-OP: all 66 are top-level function declarations, so while app.js is
still a classic script `Object.assign(window, {...})` only re-assigns what
`window` already has. That is what makes it safe to land on its own, ahead of
the flip that needs it.

The consumers are wider than the inline handlers in index.html:
  - inline on*= handlers in static/v3/index.html
  - on*= handlers app.js BUILDS inside template literals (goFavPage,
    updatePlugin, hideScanBanner, ...) — they resolve against window at CLICK
    time, but live in a JS string, so scanning the HTML alone never finds them
  - static/v3/*.js (showScreen alone has 17 consumers), capabilities
  - feedback-desktop and the external plugin repos — easy to miss, they live in
    other repos and no core test covers them
  - capabilities/visualization.js reads window.setViz behind a `typeof` guard,
    so losing it DEGRADES IN SILENCE rather than throwing

Constitution II names window.playSong / window.showScreen / window.feedBack as
the public extension contract, so this is an obligation, not a convenience.

FOUR names are invisible to every static tool. app.js:2156-2157 picks the
handler NAME at runtime —
    const letterFn = favoritesOnly ? 'filterFavTreeLetter' : 'filterTreeLetter';
— and interpolates it into `onclick="${letterFn}('A')"`. The names exist only
inside string literals, so ESLint, no-undef, and any grep for `onclick="fn` all
miss them. They are the library A-Z rail and its pagination: drop one and those
buttons throw at click time and nowhere else.

New tests/js/window_contract.test.js scrapes the HTML's handlers AND app.js's
template-literal handlers, and pins the 4 runtime-composed names by hand.
Verified to BITE: dropping showScreen, goTreePage, or setViz each fails it with
the right message.

On-device: 28 A-Z rail buttons render with their real onclick sources
(filterTreeLetter('A'), ...) and 8/8 execute with no ReferenceError; all 66
names resolve on window in the browser.

refactor(ui): defer every classic script, keep boot() on DOMContentLoaded (R3a) (#872)
Puts every external `<script>` in the v3 shell into the deferred queue, and
keeps each script's boot() firing at DOMContentLoaded exactly as it does today.
Behaviourally a no-op; it is what makes the ES-module flips safe.

WHY. `type="module"` defers execution to after HTML parse. Classic-`defer` and
module scripts share ONE "execute after parsing" list and run in DOCUMENT ORDER,
but a plain classic script runs DURING parse — ahead of all of them. So the
moment capabilities.js becomes a module while app.js is still plain, app.js runs
FIRST, and its 11 top-level `window.feedBack.on(...)` calls (app.js:6245-6722)
hit a bare `{}` — `_ensureFeedBackEventBus()` (capabilities.js:33), which
attaches .on/.emit/.off, would not have run yet. TypeError, app.js dies
mid-parse. Deferring everything now keeps document order == execution order
through the rest of the migration.

THE CATCH (Codex preflight caught this — a real ordering change). 22 scripts
guard their boot with `if (document.readyState === 'loading')`. A deferred
script runs at readyState 'interactive', so that test is FALSE and the else-branch
fires boot() immediately, at the script's position in document order — instead of
at DOMContentLoaded, after every script has evaluated.

That matters far more than one call site: a scan of the shell's scripts found
**43 forward references** where a script's boot() reads a global that a LATER
script defines (shell.js -> profile.js's window.v3Onboarding, songs.js ->
settings.js's window._confirmDialog, badges.js -> songs.js's
window.displayTuningName, ...). Every one of them resolves today only because
all boots happen at DOMContentLoaded. So the guards now treat 'interactive' as
not-ready (`!== 'complete'`), restoring that exactly.

Codex's specific finding (first-run onboarding silently skipped) did NOT
reproduce — shell.js's boot() awaits /api/profile, and that yield lets the
remaining deferred scripts run first. But the race it described is real, the
guard is silent when it fails (`&& window.v3Onboarding`), and the other 42
forward refs have no such await protecting them. Fixed at the root rather than
at the one site.

VERIFIED. A/B against origin/main on a fresh profile, 13 probes (onboarding
overlay, v3Onboarding/v3Songs/v3Profile/fbNotify/v3Badges/uiPrompt/showScreen,
bus, capabilities.version, createHighway, plugin scripts, mounted screens):
IDENTICAL, zero console/page errors on both. pytest 2396, node 1028/1028,
ESLint 0 errors, Codex 0.

New guard: test_every_external_script_defers_so_document_order_is_execution_order
fails if any external tag is plain classic — verified to fail on a single
reverted tag, so it actually bites.

refactor(ui)!: remove the classic v2 shell — v3 is the only UI (R3a) (#871)
* refactor(ui)!: remove the classic v2 shell — v3 is the only UI (R3a)

Deletes `static/index.html`, the `/v2` route, and the `FEEDBACK_UI` v2/legacy
opt-out. `/` and `/v3` both serve `static/v3/index.html`, which has been the
default since 0.3.0.

This is step 0 of the core-frontend ES-module migration (R3a). Both shells load
the same `static/app.js`, so every later step of that migration — exposing the
window contract, the `defer` ordering fix, the `type="module"` flips — would
otherwise have to be made and verified twice. Removing the fallback now halves
that surface before any of it is touched.

Incidentally fixes a latent bug in `index()`: its guard read
`if getenv_compat("FEEDBACK_UI") or getenv_compat("FEEDBACK_UI") in ("v2", "legacy")`,
whose left operand is truthy for *any* non-empty value — so `FEEDBACK_UI=v3`
actually served the **v2** shell.

- `static/tailwind.min.css` regenerated: the content globs scanned the deleted
  file, so v2-only utility classes are now purged (CI's tailwind-fresh job
  rebuilds and diffs it).
- Constitution amended to 1.3.0 — Principle II's frontend file list now names
  `static/v3/index.html`.
- Tests: 4 suites read the v2 shell (3 via a constructed `path.join` that a
  literal grep misses). Their v2 halves are paired duplicates of v3 tests that
  stay, so they are dropped; `alpha_warning_banner` and the capability-registry
  script-order test retarget to `static/v3/index.html`.

BREAKING CHANGE: `FEEDBACK_UI=v2` / `=legacy` and the `/v2` route are gone.
Unset the variable and use `/`. No chart, settings, or plugin data changes, and
no plugin API changes — v3 reuses the same engine.

* docs: drop the stale '/ is v2' plugin-verification guidance (CodeRabbit)

The v3-only rewrite updated the intro paragraphs but left three lines that
still instructed plugin authors to verify in 'both / (v2) and /v3' — now the
same shell. Historical 'in v2 it was X' contrasts are kept: they still orient
authors whose plugins also ship to users on older cores.

feat(audio): loopback feeder mode — all app audio under exclusive/ASIO (#865)
* feat(audio): loopback feeder mode — all app audio under exclusive/ASIO

Tester-confirmed (2026-07-11 log): song previews and other
plugin-private audio bypass the per-surface feeder taps and leak to the
default WASAPI device under ASIO output. Also confirmed: the element
capture path poisons itself when highway_3d already owns #audio's
one-shot MediaElementSource (InvalidStateError with _elCtx assigned
pre-throw → TypeError every later tick).

- New preferred mode 'loopback': one getDisplayMedia frame-audio capture
  (desktop main answers with the app's own frame) covers song, previews,
  and UI sounds for the whole exclusive session — engages even with no
  song loaded. Local playback silenced via suppressLocalAudioPlayback,
  page-mute IPC fallback otherwise.
- Sticky fallback to the existing stems/element surface modes when
  capture is unavailable (old desktop main, denied, Docker sphere).
- Element capture: assign module state only after the whole chain
  succeeds; close the context on failure — collision now retries clean.
- Failed engage now disables the bus and tears down loopback (no more
  bus-enabled-with-no-producer stranding).
- Tests: 12 (5 new — loopback engage/preference/mute-fallback/sticky
  fallback, collision retry).

refactor(highway): lift 79 per-instance closure vars into hwState (R3c H lift) (#849)
* refactor(highway): lift 79 per-instance closure vars into `hwState` (R3c H lift)

Collapses createHighway()'s 79 mutable closure `let`s into one per-instance
`hwState` object. Scope-resolved rewrite via acorn + eslint-scope: 1059 edits
(1057 references + 79 defs - the deleted `let canvas, ctx, ws`), with the four
names shadowed in inner scopes (chartTime/ctx/notes/chordTemplates) resolved
correctly so only closure-bound refs move. Enables the later module split:
extracted renderer/ws modules close over `hwState` as a factory arg, so
multi-panel plugins (highway_3d, note_detect, splitscreen) don't share one
highway's state.

Container is `hwState`, NOT `H` — `H` is already canvas height (70 uses). The
frame-time gate caught that collision instantly (0 draws, `H._drawHooks is not
iterable` in the shared draw-hook path).

PERF (the whole risk): identical to the pre-lift baseline. Draw p50 2.1-2.2 ms,
p95 2.7-3.0 ms (pre-lift 2.7-3.2), measured on the Arcturus feedpak, headless.
Each closure-slot read became a `hwState.<slot>` monomorphic property load; the
hot loop pays nothing. On-device: Byron confirmed the 2D highway plays smoothly.

Tests: the ~30 highway JS suites brace-extract functions/patterns from the
source; their state references + the monotonic-clock vm sandbox now use
`hwState.<slot>` (the const _CHART_MAX_INTERP_MS etc. stay top-level, not
lifted). node --test: 1030/1030 green. Two self-inflicted over-replacements
caught and reverted (`_lefty` is a prefix of the 3D-local `_leftyCached`;
`STRING_COLORS` a suffix of `DEFAULT_STRING_COLORS`) — substring replaces on the
brace-extract regexes need word care.

feat(audio): route feedpak full-mix natively under exclusive output (#824)
Song playback runs through the renderer, which WASAPI-exclusive (and
ASIO) output silences. Route single-mix feedpaks (stem-less
original_audio packs AND single-stem packs) onto the engine's backing
transport when the output device type is exclusive-style, and migrate
back to HTML5 when it isn't. Extends /api/audio-local-path to resolve
/api/sloppak/.../file/... URLs via the same containment guards as
serve_sloppak_file. Multi-stem packs stay on the WebAudio path
(Phase 2). Includes [feedpak-route] transition-gated diagnostics
logging.

fix(audio-effects): accept pre-rebrand chain plan schema as alias (#816)
* 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.

The rebrand renamed PLAN_SCHEMA to 'feedBack.audio_effects.chain_plan.v1'
but shipped plugin bundles (rig_builder <= 2.9.x) still send the
slopsmith-era id, so _validatePlan rejected every plan and providers fell
back to their heavyweight legacy load paths (full chain rebuild per poll
cycle — audible as continuous distortion during songs). Accept the old id
as an explicit alias.

feat(library): sort and badge by personal difficulty rating (#810)
* feat(library): sort and badge by personal difficulty rating

Adds sort=difficulty/difficulty-desc to the library API (correlated
subquery over song_user_meta.user_difficulty, unrated songs pushed to
the bottom either direction, same pattern as the existing mastery
sort) and surfaces the rating as a badge on library cards in both the
v2 grid/tree views and the v3 grid. The rating itself already existed
(song_user_meta) — this just makes it sortable and visible, so it's
no longer only readable in the per-song edit drawer.

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

* fix(library): escape difficulty badge, wire tree view, add changelog+tests

- Wrap song.user_difficulty in esc() at both badge call sites
  (static/app.js ~2082 and ~2283) for XSS-consistency with the
  sibling tuning badge, which already uses esc().
- server.py: query_artists (the classic tree view's data source, used
  by /api/library/artists) never batch-attached user_difficulty the
  way query_page does for the grid, so the tree-view difficulty badge
  added in 75673c3 was unreachable dead code (song.user_difficulty was
  always undefined there). Now attaches it via the existing
  user_meta_map() helper, same pattern as query_page.
- Add an [Unreleased] CHANGELOG.md entry for the difficulty sort +
  badge feature, matching the repo's existing entry format.
- Add tests/test_library_filters.py::test_difficulty_sort_pushes_unrated_to_bottom
  asserting unrated songs sort to the bottom in both sort=difficulty
  and sort=difficulty-desc directions, and
  ::test_tree_view_songs_carry_user_difficulty covering the
  query_artists fix above.

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.

92e78be62d Fix v3 library Filters drawer crash on saved prefs; rename Stems label
applySavedPrefs() rebuilt state.filters without the `genre` key, so with
saved prefs restored from localStorage state.filters.genre was undefined.
Clicking Filters ran renderDrawer(), which indexes f.genre.includes(g)
whenever the library has >=1 genre -> TypeError, renderDrawer aborts, and
openDrawer never removes translate-x-full. The drawer stayed off-screen so
the menu appeared dead. Only triggered for users with saved prefs AND a
non-empty genre list, matching the intermittent report.

Carry genre: [] alongside the other session-only facets (mastery, match),
mirroring the default and clear-all shapes which already include it.

Also rename the visible "Stems (sloppak)" drawer label to "Stems (feedpak)"
to match the public format name used elsewhere in the UI.

fix(settings): don't let a stale DLC path block saving the Demucs server address (#795)
Some checks are pending
ship-ci / ci (push) Waiting to run
The v3 Settings "Save" button posts dlc_dir together with demucs_server_url,
default_arrangement and av_offset_ms in one request. POST /api/settings
validated dlc_dir first and early-returned "DLC directory not found" before it
ever processed demucs_server_url, so on a machine whose DLC path doesn't resolve
(fresh install, unplugged/network drive, a path carried over from another
machine) setting the Demucs server address silently failed — reported in
got-feedBack/feedBack-demucs-server#3 (macOS 07-05 nightly).

- server: a non-resolving dlc_dir is now recorded as a warning and skipped
  rather than aborting the whole POST, so the co-submitted keys still persist.
  The bad path is surfaced via a new additive `warnings` field and folded into
  `message` so the settings status line still shows it.
- client (v3): the Demucs input now autosaves on blur/enter via a single-key
  persistSetting POST, like every other v3 setting, so it never depends on the
  coupled Save button.
- tests: cover the decoupling and the unchanged happy path.

perf(highway): draw the held-sustain glow without ctx.shadowBlur (#729)
shadowBlur cost scales with the blurred device-pixel area. The lit-sustain
trail can span half the canvas, the canvas is DPR-scaled (4x pixels on a
2x Mac), and the blur ran on every frame exactly while a sustain is HELD
— i.e. at the moment the player most notices a hitch. Sustain-heavy songs
(e.g. fingerpicked acoustic charts) hit this constantly.

Replace the blur with three inflated low-alpha fills of the same trail
quad: reads as the same soft shimmering glow (the shimmer LUT still
drives per-frame flicker, feedBack#254 intent preserved) at a flat,
area-independent cost. Also drops the now-dead shadowBlur reset in the
crackle pass; no shadowBlur uses remain in highway.js.

Some checks are pending
ship-ci / ci (push) Waiting to run
* 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:
tests/js/badges_handedness.test.js.

them as pickable tiles (same apply→/art/url path; covers with no CAA art
self-hide). Pre-filled from the song's artist + album/title (romaji fallback), so

feat(v3 library): batch→popup handoff + English-base romaji (metadata-curation capstone) (#782)
* feat(v3 library): click a "No match" badge to fix it — batch → popup handoff

Connects the two halves: the "No match" badge (the unmatched pile) now opens the
Fix-metadata popup for that song in one click, instead of right-click → menu.
The resting badge becomes interactive (pointer-events-auto + hover), carrying a
data-meta-fix hook; wireCards opens window.__fbFixMatch(playTarget) on click and
stops propagation so it doesn't also play the card. Batch tile states stay
non-interactive. Loop becomes: Unmatched filter → see the pile → click one →
fix it. tailwind.min.css regenerated for the badge's hover classes.

* feat(v3 library): show the author's romaji, not blank/native script (English base)

Two changes so an English-speaking base never sees a blank name or native script:

- Filename romaji fallback: a blank-artist CDLC pack ("Artist_Title_v1_p") shows
  nothing useful (artist blank; title = the raw filename), and a match fills it
  with kanji/kana. query_page + pack_fields now surface the author's own romaji
  parsed from the filename ("Junko Yagami — BAY CITY") when the pack has no
  artist of its own — display-only, keyset-safe (raw title stashed for the
  cursor), a real pack artist or a user override still wins.
- Smart adopt: "Use these values" now KEEPS the readable romaji name + title the
  card already shows and takes only album/year/genre (+ art via the pin) from the
  match, so identifying a Japanese song gives "Junko Yagami — BAY CITY — FULL MOON"
  with the right cover, never native script.

Tests: romaji fallback fires for a blank-artist CDLC pack (grid + pack_fields
agree) and is left alone when the pack has a real artist.

feat(highway): add "Colorblind (deuteranope)" string-color preset (#788)
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(v3 library): genre field in the Fix-metadata popup Details tab (#780)
Adds Genre as a fifth Details field (edit / lock / revert / Yours-Pack
provenance), backed by the existing override store. To make it actually useful,
the genre FILTER and FACET now resolve the per-song override (effective genre =
override else scanned pack genre) — guarded so the common no-override case stays
on the plain indexed column — so a corrected/added genre is immediately
browsable. Genre stays a library-only overlay: it is NOT a write-to-file field
(split WRITE_FIELDS = the four file-safe fields from the five DETAIL_FIELDS), so
Write to file leaves the genre override in place and the copy says so. The
Match→Details bridge also carries a candidate's first genre.

Tests: effective-genre facet + filter, and that a value-less lock doesn't invent
an effective genre.

feat(library): Match→Details "use these values" bridge (#779)
Connects the popup's two tabs. A match only improves the underlying canon+art;
by design it never silently re-titles the grid. This adds the explicit opt-in
path: each Match candidate (search or Identify-by-audio) gets a "Use these
values →" action that copies its title/artist/album/year into the Details tab
as pending (unsaved) inputs and lands you there for review — pinning the match
too so the art/canon follow. You then Save (overlay) or Write to file. Queue-
review candidates are unchanged (they still accept/pin on click).

feat(v3 library): "Write to file" in the Fix-metadata popup (#778)
* feat(library): "Write to file" in the Fix-metadata popup's Details tab

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

same integer coercion client-side so the in-memory song matches what was

feat(v3 library): "Fix metadata" popup — per-song override + lock, cover picker, MusicBrainz + AcoustID (#777)
* feat(library): metadata override + lock store, enforced by enrichment (popup slices 1–2)

Backend foundation for the Fix-metadata popup. Not yet surfaced in the UI (the
display + 3-tab popup are the next slices); no PR until it's user-visible.

Slice 1 — the store:
- `song_field_override(filename, field, value, locked)` table: a reversible
  DISPLAY overlay (never written to the pack), filename-keyed so it survives a
  rescan (never purged by delete_missing) and is dropped only with the song.
- DB methods (partial upsert that drops empty+unlocked rows; batch map) +
  `GET`/`PUT /api/song/{fn}/overrides` (field allowlist title/artist/album/
  year/genre; clearing rides PUT since DELETE /api/song/{path} shadows sub-
  routes; PUT demo-blocked).

Slice 2 — locks respected by enrichment:
- The auto-matcher composes a per-song `_compose_lock_filter` onto the global
  apply-filter, so a match still applies IDENTITY (mbid/release → art) but never
  re-canonicalizes a LOCKED display field.
- Gap-fill (write-to-file) skips locked album/year/genre — writing the matched
  value would be exactly the clobber the lock exists to prevent.
- Review/manual picks bypass the filter (an explicit confirm overrides a lock).

Tests: store semantics + rescan-survival + API; the lock filter + reader; an
auto-match leaving a locked field un-canonicalized; gap-fill excluding locked
keys.

* feat(library): show per-song overrides in the grid (popup slice 3)

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

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* feat(library): 3-tab Fix-metadata popup — Details / Cover art / Match (slice 4)

Turns the thin single-song fix-match modal into the Plex-style metadata
editor reached from a card's "Fix metadata…" menu:

- Details tab: type + lock the displayed title/artist/album/year. Values
  ride the reversible override store (GET/PUT /api/song/{fn}/overrides); each
  field sits on its pack value (Yours/Pack provenance + revert-to-pack), a lock
  pins it against auto-match, and Save repaints the grid via library:changed
  (slice-3 overlay). This is the real tool for the blank-artist city-pop pile
  MusicBrainz can't surface — you just type the right title.
- Cover art tab: hands off to the shared image picker (its own modal); the
  pick refreshes the thumbnail everywhere.
- Match tab: the existing MusicBrainz search + candidate/pick flow, refactored
  into shared body/footer helpers (the queue-review flow is untouched).

Backend: GET /overrides now also returns the pack baseline so the Details tab
can pre-fill + show provenance. tailwind.min.css regenerated (build-tailwind.sh)
for the popup's new utility classes.

Identify-by-audio (AcoustID) is deferred: it lives in unmerged PR #759, off
main — the Match tab gains the button once #759 lands and this branch rebases.

* fix(library): wire "Identify by audio" in the tabbed popup's Match tab

The AcoustID Identify button (#759) merged in referencing an out-of-scope
`panel` in the wiring — a leftover from the pre-popup fix-match modal that my
tab refactor renamed to `root`. Under strict mode that threw, so the handler
never attached and the button did nothing. Scope it to `root` (the tab body),
which is where the search-results area it renders into lives.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

* fix(library): make "Identify by audio" outcomes unmistakable

An empty AcoustID result read the same as a broken button. Each state now says
plainly which outcome it is — ✓ fingerprinted-but-no-match vs no-audio vs off vs
unavailable — and, in the popup, points at the manual fallback (Search, or set
the album in Details + cover in Cover art by hand). A ✓ marks the states that
actually ran, so "worked, found nothing" no longer looks like a failure.

feat(v3 library): persistent "no match" badge + Unmatched quick filter (#781)
* feat(v3 library): persistent "no match" badge + Unmatched quick filter

The Refresh-Metadata batch (#764) shows a transient per-tile "no match" only
while a pass runs, so the unmatched pile goes quiet at rest. Two additions make
it visible + reachable:

- Persistent per-card "No match" badge: query_page now marks each row
  `unmatched` (a cheap failed-set membership like favs/estd), and enrichBadge
  paints a subtle resting marker for those cards — tracked in a `_unmatched` set
  so a batch tile clearing falls back to it instead of wiping it. A live batch
  tile still wins while a pass runs.
- "Unmatched" toolbar toggle (local-only): one click applies the same filter as
  the drawer's Match → Unmatched (match_state='failed'), so the no-match pile is
  a click away right after a batch. Re-queries + reflects active state.

Test: query_page flags a failed row + the match=unmatched filter returns it.

* fix(v3 library): repaint persistent no-match badge after metadata tile-clear

_clearMetaTiles removed every .v3-meta-tile node — including the new

than _metaTile. A metadata rescan's tile-clear therefore dropped the badge
until the next scroll re-rendered the card. Repaint it from _unmatched.

* feat(gp_autosync): piecewise time-warp helpers + refine_sync onset pass

auto_sync computes per-bar sync points but consumers only ever applied the

- 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.
