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): 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): 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 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.

* feat(diag): --debug ASIO routing diagnostics in static bundle

Gated on window.feedBackDesktop.audio.debugEnabled() (desktop --debug);
inert in the Docker sphere and normal desktop runs.

- [asio-diag] getCurrentDevice= full device object on outputType change
  (catches ASIO drivers reporting a non-'ASIO' type name)
- [asio-diag] renderer-bus: full feeder decision vector, change-gated
  (running/exclusive/stems/juceMode/elementSong/want/mode)
- [asio-diag] setSink: every sink flip with ctx state + rate

* 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).

* fix(audio): close loopback capture context on teardown (release tap worklet)

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.

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

* 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(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)!: 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).

* fix(audio): close loopback capture context on teardown (release tap worklet)

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.

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.

Transformer saved at ~/.local/share/feedback-editor/highway-h-lift.mjs.

* test(highway): pin the setNoteStateProvider assertion to hwState._noteStateProvider (CodeRabbit)

The [^}]* form matched an unqualified _noteStateProvider =, so a regression to
closure-level state could still pass. Require the hwState-qualified assignment.

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.

feat(v3): choose handedness in the instrument selector + onboarding (give lefties a break) (#793)
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.

fix(highway_3d): recover from WebGL context loss instead of crashing on alt-tab (#790)
Switching the active window / alt-tabbing away (most often on Windows) can
trigger a GPU context reset. The 3D highway's WebGL renderer had no
webglcontextlost handler, so a lost context was left to escalate into a
render-process crash -- matching the intermittent "randomly crashes when I
change windows" desktop reports.

The renderer now binds webglcontextlost/webglcontextrestored on its own WebGL
canvas (ren.domElement): the loss is preventDefault()'d so the browser keeps the
context restorable, draw() bails while the context is down so no GL work runs on
a dead context, and on restore the viewport is re-applied and rendering resumes
(Three re-uploads scene resources on the next frame). Listeners are removed in
teardown.

Root cause is a strong hypothesis -- the crash is intermittent and
unreproducible -- but the fix is low-risk and additive and closes a real gap:
there was no context-loss handling anywhere in the renderer.

plugins/highway_3d 3.31.2 -> 3.31.3. Tests:
tests/js/highway_3d_context_loss.test.js (source-contract, like the other
highway_* tests). The sibling keys_highway_3d / drum_highway_3d renderers share
the same gap -- follow-up in their repos.

fix(v3): recycle library grid cards on scroll instead of rebuilding the window (#742)
The virtualized v3 Songs grid rebuilt its entire visible window
(grid.innerHTML = _renderCardsRange(...) + a full wireCards pass) every
time it slid by one row. Each row-boundary crossing was therefore a heavy
synchronous frame — reparse ~60 cards, re-attach hundreds of listeners,
reflow — that stalled the main thread and buffered held-arrow key-repeats,
flushing them in a burst. Testers saw the library "go super fast for a
second then slow down," skipping "every so many scrolls," up or down, at
the same spots each time. It hitched scrolling back up over already-loaded
songs too, because the cost was DOM teardown, not fetching.

renderWindow() now reconciles the window in place: it reuses the card
nodes that stay on-screen and builds only the row that enters/leaves
(~6 nodes per slide instead of ~60). Nodes are keyed by absolute index
(data-idx) with a real-vs-skeleton + select-mode signature (data-sig) so
hole-fills after a page fetch and select-mode toggles still rebuild
exactly the nodes that changed. wireCards()'s existing data-wired guard
then wires only the freshly-built nodes, so per-slide listener churn drops
with it. Everything keyed off data-fn (favorites, ⋮ menu, right-click,
selection, accuracy badges, A–Z rail) is unaffected.

Follow-up to the stage-2 virtualized grid (#636 item 3). Frontend-only.

Tests: tests/js/v3_songs_window_recycle.test.js — window stays [start,end)
contiguous and in-window node identity is reused across a down-then-up
scroll; select-mode toggle and a rail-seek jump rebuild correctly.

settings: add host instrument profiles (#753)
* settings: add host instrument profiles

Signed-off-by: ChrisBeWithYou <christian.a.cowan@gmail.com>

* settings: add instrument pathway selection

Signed-off-by: ChrisBeWithYou <christian.a.cowan@gmail.com>

* fix(settings): profile-aware saves/resets/switch, provider tunings, bass-5

Five regressions from the instrument-profiles rework:

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

* fix(settings): partial-merge instrument_profiles; clamp tuning on string-count switch

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

fix(plugins): don't treat transient absence from /api/plugins as uninstall (#741)
* fix(plugins): don't treat transient absence from /api/plugins as uninstall

The backend clears its plugin registry at the start of load_plugins()
and repopulates it incrementally while HTTP stays up, so every backend
restart (desktop: Audio Quality soundfont switch, LAN toggle, update
restart) serves a window of partial — even empty — /api/plugins
responses. loadPlugins() treated absence from the current response as
an uninstall, with three destructive consequences for still-loaded
plugins:

1. Their settings-panel and screen DOM were wiped while their
   _loadedPluginScripts entry survived, so the NEXT refetch failed the
   DOM-existence check and re-evaluated the plugin's screen.js
   mid-session. For the desktop audio_engine plugin that re-ran init()
   against the surviving native audio chain and exactly duplicated
   every VST/NAM/IR stage (the alpha testers' "chain duplicates after
   leaving the Audio menu" / blown-out gain reports).
2. _reconcilePluginStyles dropped their stylesheet, leaving them
   visible but unstyled until they reappeared.
3. The stale-contribution sweep unmounted their UI contributions and
   unregistered their capability participant with no re-registration
   path (plugin scripts don't re-run thanks to the loadedScripts
   guard).

Absence is now a non-signal everywhere in loadPlugins: the DOM wipe and
style reconcile are scoped to plugins the response actually names, and
the absence sweep is removed. Present plugins still fully re-sync via
_registerLegacyPluginUiContributions each round; failed plugins are
present in the response and still cleaned up; nav is rebuilt from the
response so genuinely uninstalled plugins drop out of it, and their
(un-unloadable) already-evaluated scripts keep their DOM until reload.

deletes; pin the new invariant instead (no absence sweep + respondedIds
scoping on the DOM/style reconcilers).

fix(tests): re-green the JS suite — 18 stale source-shape tests + 1 real seek-reason violation (#740)
main's JS suite has been red since the recent v3-library and player
refactors landed. 17 of 18 failures were test harnesses/regexes that
went stale behind real, intentional code changes; one was a genuine
contract violation in the code.

Code fix:
- session-resume seek passed 'resume' as its _audioSeek reason; the
  documented contract (enforced by song_seek.test.js) requires
  multi-word kebab-case. Renamed to 'session-resume' — no consumer
  string-matches specific reasons, so this is rename-safe.

Test updates (each pins the CURRENT contract):
- highway_colors_facade: inject HWC_PRESETS + applyHighwayStringPreset
  (new preset feature); lock presets/applyPreset into the surface test
- loop_api: stub _updateEditRegionBtn (new edit-region UI hook)
- song_close: sandbox gets window.feedBack.playQueue; assert a real
  close abandons the queue (the new queue-aware behavior)
- v3_keep_practicing: the shelf moved from client-side /api/stats/recent
  dedupe+gating to the server-side practice-suggestions recommender —
  tests now pin that (fetch, arrangement-aware card click, Promise.all)
- v3_songs_tuning: card row variable renamed song → shown (grouped cards)
- live_guitar_tone_source: accept literal ’ where &rsquo; drifted in copy
- legacy_shim_hits: normalize CRLF before fixed-width region() slicing
  (Windows-only failure; char windows shrank by one char per line)

Suite: 987/987 locally (Windows), previously 968/987 (and 18 red on CI).

Fix 3D drum/keys highways not resizing on fullscreen under splitscreen (#723)
The guitar/bass highway_3d renderer self-detects panel-canvas size changes
in its draw() loop and re-runs applySize() every frame, because the
splitscreen host overrides hw.resize and never calls renderer.resize().
The drum and keys highways lacked that fallback — they only re-framed when
the host explicitly called resize(w, h) — so their panels stayed framed for
the pre-fullscreen size while the guitar/bass panels adapted. Symptom: a
too-small, off-center highway in the drum/keys panels after maximizing a
split-screen session.

Port highway_3d's per-frame drift check into both draw() loops: re-apply on
backing-store change (canvas.width/height) AND on CSS-box drift
(clientWidth/clientHeight vs the last applied logical size, throttled to
every 10th frame). Track _lastHwW/_lastHwH + _appliedW/_appliedH per
instance and reset them in destroy() so a reused instance re-frames on the
next song.

plugins/drum_highway_3d -> 0.3.1, plugins/keys_highway_3d -> 0.1.1.
Tests: tests/js/drum_keys_highway_3d_resize_reframe.test.js.

Fix v3 Songs A–Z rail: reliable taps, precise drag, hittable size (#653)
* Fix v3 Songs A–Z rail: reliable taps, precise drag, hittable size

Follow-up to #634. Three rail bugs reported on macOS + Windows (0.3.0,
2026-06-29 — =Scr4tch=, MajorMokoto):

- Taps often did nothing ("clicked O, nothing happened"). pointerdown
  calls setPointerCapture, after which the browser retargets the
  follow-up click to the rail container, so the click handler's
  closest('.v3-azrail-letter') resolved null and a plain tap (no
  pointermove) had no other path. Drive the jump from pointerdown
  itself; reduce the click handler to keyboard activation only
  (e.detail === 0, Enter/Space).

- A drag landed short of the release ("where you release isn't where
  you get sent"). Every letter crossed fired jumpToLetter with
  behavior:'smooth'; stacked smooth-scroll animations over the
  virtualized grid lagged and settled imprecisely. jumpToLetter now
  takes a smooth flag and scrolls instantly ('auto') while scrubbing,
  animating only discrete taps/keyboard jumps, so the grid tracks the
  finger and the release lands on the let-go letter.

- The rail was too small at 1440p and didn't scale. Letters were a
  fixed .62rem glued at right:2px (~13px-tall target). They now scale
  with the viewport (clamp(.72rem, 1.4vh, 1.05rem)), sit off the edge

Fix v3 Songs List View favorite heart staying dim until re-search (#654)
Favoriting from the tree / "List View" flipped the glyph ♡→♥ but the
heart stayed grey until a re-search — reported macOS+Windows, open since
0.3.0 / 2026-06-25.

One shared wireCards() [data-fav] handler serves both the grid card and
the List-View row, but they render with different idle colours (grid
text-white, List View text-fb-textDim) and the handler only ever removed
the grid's text-white. So in List View text-fb-textDim lingered next to
the freshly-added text-fb-accent and won by CSS source order — the glyph
changed but the colour didn't, until a re-search re-rendered the row.

Each heart now declares its idle colour via a data-fav-idle attribute;
the handler swaps exactly that class (so only one colour class is ever
present) and writes the new state back onto the in-memory song model so a
re-render / virtualized-grid recycle agrees instead of reverting.

Tests: tests/js/v3_favorites_toggle.test.js. Full JS suite 810 tests; the
13 pre-existing unrelated failures are unchanged.

feat(v3): host theme read surface — window.feedBack.theme + always-present --fbv-* tokens (#646)
First slice of the host theme contract (#644): give plugins a host-owned way to
read the active theme + its device affordances, so a feature renders correctly
under any theme instead of binding to whichever one the dev saw.

theme-core.js previously only APPLIED themes and emitted --fbv-* vars only while
a theme was equipped (nothing to read in the default state), with no read API.
Now, all additive + feature-detected:

- Always-present default `fb` palette as `--fbv-*` on :root (the un-themed look
  is unchanged — fb-* utilities still use their compiled defaults; this only
  hands plugins a stable host token to read + derive surfaces from). Adds two
  keystone ROLES the palette lacked: `on-accent` (legible fg on the accent fill)
  and `focus-ring`.
- window.feedBack.theme.get() -> {id, isThemed, tokens}; .capabilities() ->
  {glow, gradients, motion} (the device-affordance signal; recolor-only themes
  report defaults, a theme may opt out via `capabilities` in its payload, motion
  is reduced-motion-gated); .prefersReducedMotion().
- Normalized `theme:changed` event from the single apply() chokepoint.

The apply side stays on window.v3Theme; the read surface is attached defensively
so it survives the feedBack bus being (re)built by capabilities.js regardless of
load order. Verified via a headless render (apply/unequip intact, defaults
present + restored, capability opt-out honored, event payload correct) +
tests/js/v3_theme_read_api.test.js. See docs/host-theme-contract.md.

fix(tuner): remove unused settings + fix sidebar panel position (#661)
Removes the Floating Button and Tuning Visibility settings sections and finishes retiring their still-live config: drops the disabledTunings menu filter and showFloatingButton gate from screen.js/ui.js and their persistence in routes.py (retired keys are stripped on write). Repositions the tuner panel opened from the v3 sidebar Plugins popover to anchor beside it via the host's stable plugin-control slot API (falling back to the popover id), clamped to the viewport so it can't open off-screen, and re-anchored on resize. Updates tuner config tests to the retired-key behavior; plugins/tuner 1.3.2 -> 1.3.3.

59aa70ce5a perf: remove throttled-trace residuals — program churn, per-frame rect, HUD clock
A 4x-CPU-throttled retrace (the honest weak-hardware proxy) surfaced
three residual per-frame costs; stack attribution pinned each:

- getParameters/getProgramCacheKey (~4% of main thread): every pooled
  label sprite map swap set material.needsUpdate, bumping
  material.version and forcing full program re-resolution next render.
  Swapping between two non-null cached textures never changes the
  compiled program (USE_MAP define unchanged) — new _setLabelMap()
  helper only flags needsUpdate on a null<->texture transition, used at
  all 7 swap sites.
- getBoundingClientRect (~1.2%): the 3D highway's per-frame canvas-size
  self-check forced a layout read every frame. The CSS-box drift read
  now runs every 10th frame (or when the wrap isn't pinned); the
  backing-store comparison stays per-frame with cheap property reads
  and forces an immediate box read + applySize when it fires.
- set textContent: the core 60 Hz HUD clock rewrote hud-time (and
  getElementById'd it) every tick for a display that changes 1/s — now
  write-on-change with a cached element ref.

(The remaining textContent writer in the trace is notedetect's
badges.js — external repo, to be filed there.)

tests/js: resize-reframe shape test updated for the hoisted _bsChanged
gate, incl. an assertion that the throttle can never delay the
backing-store path.

77547af110 perf: allocation/scan hardening for weaker hardware
Static-analysis follow-ups to the trace-backed fixes; each is cheap
insurance on machines where the profiled headroom doesn't exist.

- highway.js: _makeBundle now mutates one persistent per-instance
  object instead of allocating a fresh ~35-field bundle every rAF
  frame (xN under splitscreen). Object identity is stable and
  meaningless; array fields still swap reference on chart changes,
  which field-identity caches rely on. Contract documented in both
  CLAUDE.mds.
- highway.js: new bsearchTime (lower-bound on .time) windows the
  default 2D renderer's beat-line scan (was O(all beats) per frame);
  bundle.lowerBoundT / bundle.lowerBoundTime expose the searches to
  custom viz so they stop reimplementing visible-window culling.
- highway_3d: localStorage 'h3d_full_sus' polled at ~1 Hz instead of
  every frame (synchronous storage read on the hot path).
- highway_3d: drawLyrics caches the measureText row layout keyed on
  (lyrics ref, line index, shown count, font size, width) — per-frame
  work is now just drawing over cached widths.
- tests/js: bundle source-shape assertions widened to accept the
  assignment form ([:=]) alongside the old object-literal form.

fix(tuner): mic-verify stamps the tuning it actually checked + on-device test plan (#684)
Working-tuning follow-ups:

- Mic-verify used _state.currentSongOffsets for the 'verified' stamp, but for a
  MANUALLY-selected tuning (tuner opened off a song) that's a stale/different
  song's tuning — so verify could mark the WRONG tuning verified. It now derives
  the verified offsets from the tuning actually being checked (its target freqs;
  the player's reference pitch cancels in the ratio), so 'verified' always
  attaches to the tuning the player confirmed. Explicit offsets still win.

- Adds docs/working-tuning-on-device-tests.md: the checklist for the parts that
  can't be covered headlessly — the auto-open/gate flow, both-directions prompts,
  mic-verify detection, and the tuner-mic-vs-note_detect ASIO/exclusive-mode
  contention flagged in the design charrette.

Test: mic-verify with no explicit offsets / no song context derives the correct
offsets (Drop-D). 55 tuner tests green.

feat(tuner): mic-verify — promote working tuning assumed→verified via a per-string check (working-tuning PR 9b) (#670)
* feat(tuner): mic-verify — promote the working tuning assumed→verified via a per-string check (working-tuning PR 9b)

Adds the choreographed per-string mic verification the design reserved for
'verified' provenance (audio-engine's honesty rule — nothing else may claim it):
the player plays each string, and once every one reads in tune (±6 cents) and
holds stable for 8 frames, the tuner stamps the working tuning
provenance:'verified' + verifiedStrings via workingTuning.set.

- screen.js: a pure verify state machine (verifyStart/verifyFeed/verifyCancel/
  verifyState, exposed on the tuner API) + the set-verified writer; cancels on close.
- ui.js: updateUI feeds each processed frame (matched string + cents) into the
  session; a "Verify tuning" button + per-string progress + status, shown for a
  selected (non-free) tuning.

Pairs with the 9a lifecycle: a 'verified' decays back to 'assumed' on the next
song load, so mic-verify is a per-session confidence boost, never a sticky claim.

Tests: tests/js/tuner_auto_open.test.js +4 (all-strings->verified, out-of-tune
never completes, streak resets on drift, API exposed / only it claims verified) —
33/33. The state machine is headless-verified with synthetic frames; the real
per-string mic detection + the button flow need an on-device pass.

* fix(tuner): mic-verify writes the confirmed tuning + no clobber + stricter streak (PR #670 review)

Review fixes for mic-verify (working-tuning PR 9b):

- 'verified' could attach to STALE offsets: _publishVerified stamped provenance
  without writing offsets, so the slot's pre-tuning offsets got marked verified.
  verifyStart(targets, offsets) now captures the confirmed tuning's offsets, and
  _publishVerified writes offsets + stringCount + instrument + referencePitch +
  verifiedStrings ATOMICALLY with provenance:'verified' into the selected slot
  (and refuses to stamp verified with no concrete offsets).
- The assumed publish-on-clear immediately clobbered a just-earned 'verified':
  disable() now skips it when a mic-verify wrote verified this session
  (_verifiedPublished).
- The per-string streak could accumulate across silence / wrong-string frames.
  verifyFeed now requires CONSECUTIVE in-tune frames: the one confirmed string
  advances, every other unfinished string resets each frame.
- A mid-verify tuning change (song switch) left stale captured offsets; verify is
  now cancelled in _syncCurrentTuning when the song tuning changes.

Tests: verify writes the confirmed offsets (not stale); source-guard for the
no-clobber path. 47 tuner + 77 tuner/capability tests green. Codex-reviewed.

feat(tuner): gate playback until you've tuned — hold autoplay + no-trap Skip/Back/Esc (working-tuning PR 4) (#666)
* feat(tuner): gate playback until you've tuned — hold autoplay + no-trap Skip/Back/Esc (working-tuning PR 4)

When the opt-in auto-open fires because a song needs a different tuning, playback
now WAITS behind the tuner instead of starting underneath it — the "tune before
you play" model. Built on a new generic core hook window.feedBack.holdAutoplay()
(mirrors holdAutoExit): the tuner claims the hold synchronously on song:loading
(beating the song:ready autostart) and releases it — or a 12s fail-open backstop
does — so a wedged plugin can never strand a song. Generation-guarded; manual
Play always wins.

No one-way trap:
- Skip = "I've tuned" -> plays and records the song's tuning as the instrument's
  current working tuning (the explicit write-point PR 3 left as 'assumed').
- Back to library / Esc -> leave the song, record nothing (reuses requestExitSong;
  Esc is the existing player shortcut).
- The in-panel x is dropped for an auto-open — Skip/Back/Esc are the dismiss
  surface. This also keeps the write honest: Skip is the only on-player dismiss
  that records, so leaving never falsely records a tuning.

Stacked on #660 (working-tuning PR 3). Core app.js gains only the generic hook
(a test asserts it never references the tuner's internals); shell-agnostic.

Needs a desktop smoke-test that the tuner mic doesn't contend with note_detect's
scoring input under ASIO/exclusive mode (per the design charrette).

* fix(tuner): backstop can't cut off tuning + gate race/token hardening (PR #666 review)

Review fixes for the autoplay gate:

- The 12s fail-open backstop could start playback UNDER a legitimately-open tuner
  (a slow / mic-verify retune > 12s). holdAutoplay()'s release now carries a
  .settle() that cancels the backstop; the tuner calls it once the tuner is
  confirmed open (_gateClaimed), so the hold becomes deliberate and only a
  dismiss / song switch releases it. (Fail-open still covers "claimed but wedged
  before deciding".)
- The async song:ready handler could release a NEWER song's gate after its await
  (global _gateClaimed, no guard). It now snapshots _autoOpenGeneration and bails
  if a newer song took over.
- holdAutoplay guarded by song generation, not per-hold — a stale release from an
  earlier hold could clear a later one. Each hold now mints a unique token that
  release()/settle() must match.

Tests: source-level assertions for the token, settle(), the settle-on-open call,
and the song:ready gen-guard. 45 tuner+speed tests green. Codex-reviewed.

feat(core): working-tuning lifecycle — launch default, verified decay, idempotent re-injection + tests (working-tuning PR 9a) (#669)
Hardens the host workingTuning capability (PR 1) with the "polish & safety"
lifecycle:

- Idempotent re-injection: a second load of the module no longer replaces the live
  state with a fresh (empty) one — it early-returns once registered.
- Opt-in "launch tuning" default (setLaunchDefault/getLaunchDefault/clearLaunchDefault):
  a per-instrument, localStorage-backed seed the player can opt into ("start me in
  THIS tuning on app open"). Boot seeds from it when set, else /api/settings as before.
  Off by default — a SEED only; the live tuning still resets on restart.
- Verified decay: on song:loading the current instrument's 'verified' provenance
  decays to 'assumed' (offsets kept) — a per-string mic check is only trustworthy for
  the context it was done in, so a stale 'verified' can never suppress a needed prompt.

Adds a state-machine smoke suite (tests/js/working_tuning_capability.test.js, 12/12):
defaults, per-instrument isolation, both-directions, verified-invalidation-on-retune,
decay-on-song-load, resetToDefault, launch-default set/seed/clear, idempotent
re-injection, the change event.

The opt-in UI + the mic-verify writer land with the tuner (PR 9b).

feat(v3): flag library songs by working-tuning match (working-tuning PR 6) (#668)
* feat(v3): flag library songs by working-tuning match (working-tuning PR 6)

Each song's tuning chip in the v3 library grid is now coloured by whether your
CURRENT working tuning covers it: green = play it now, amber = needs a retune
(with a matching tooltip). Uses the tuner plugin's coverageReport (async), so it
runs as a post-paint decoration pass — chips render instantly, then colour a tick
later; a token cancels a superseded pass so scrolling stays snappy. Re-flags on
working-tuning-changed (retune / instrument swap / reset), no re-fetch.

Fully feature-detected: without the tuner coverage API + the host workingTuning
state, the chips render exactly as before. v3-only, single file (static/v3/songs.js).

* fix(tuner/library): correct bass matching + memoize player tuning (PR #668 review)

Review fixes for working-tuning PR 6 (library tuning-match chips):

- Bass songs were scored against the guitar tuning. The chip passed no arrangement
  to coverageReport, so isBassArrangement fell back to guitar — a 4-string bass
  drop-D read as guitar could FALSE-MATCH a drop-D guitar player (green). songCard
  now flags a bass-only song (every arrangement name matches /\bbass\b/) with
  data-tuning-bass, and decorateTuningChips passes arrangement 'Bass'/'Lead' so
  coverage uses the right base pitches. Mixed guitar+bass songs → guitar (the
  song-level tuning is the guitar one); least-wrong given one tuning per song.

- Per-chip /api/settings fetch storm. coverageReport()→_playerTuning() fetched
  /api/settings once per visible chip per grid paint (~60). _playerTuning is now
  memoized (the player's tuning is song-independent) so all callers share one read;
  invalidated on instrument:changed / working-tuning-changed, with a 3s TTL so a
  settings write that doesn't emit an event still heals. A transient fetch failure
  is NOT cached (next read retries) — else one hiccup would freeze coverage.

Tests: player tuning shared across songs (one fetch); transient-failure retry
(fails without the fix). The prior #680 dedup test updated for the memoized behavior.

Tuner: passive "different tuning" badge cue naming the retune (issue E, stage 2.5/3) (#657)
* Tuner: passive "different tuning" badge cue that names the retune

Building on the coverage check: when you enter a song your current
instrument doesn't cover, the topbar tuner badge gets an amber ring + a
tooltip naming the change (e.g. "retune B->A", or "the reference pitch"
for an A440 vs A432 mismatch). Advisory only -- it never auto-opens the
panel; recomputed on song:ready, cleared on song-load / leaving the
player.

Refactors the coverage check into a structured report
(window._tunerAutoOpen.coverageReport -> { covered, retune:[{from,to}],
reference, cantCover }); the boolean gate now wraps it. The cue is
CSS-free (inline ring + native tooltip, no Tailwind rebuild) and no-ops
when the tuner plugin is absent.

Touches static/v3/badges.js (cue) + plugins/tuner/screen.js (report).
v3-only. Stacked on #656 (issue E stage 2.5/3). The splitscreen-suppress
and no-usable-input guards move to E2 (the playback gate).

Tests: tests/js/tuner_auto_open.test.js (report names the strings,
reference mismatch, badge wiring).

* feat(tuner): read/write the live per-instrument working tuning — both-directions retune prompt (working-tuning PR 3) (#660)

The §4 coverage check compared each song against the player's fixed
instrument-profile tuning, so the tuner only ever prompted *away* from a "home"
tuning (E -> Drop C#) and stayed silent coming back (Drop C# -> E), even though
the player had physically retuned.

_playerTuning() now reads the host's live per-instrument working tuning
(window.feedBack.workingTuning, keyed by the selected instrument from
/api/settings) instead of re-deriving from the static settings tuning, so
coverage is measured against what the instrument is ACTUALLY in and prompts both
directions. On clearing an auto-opened tuner, _publishWorkingTuning() writes that
song's tuning as the instrument's live working tuning ('assumed' — PR 4's
explicit "I tuned / Skip" refines the write-point), so the next song is judged
against where the player now is.

Per-instrument (guitar vs bass tracked separately). Feature-detected: falls back
to the static /api/settings tuning when the working-tuning capability is absent,
so the 27 existing coverage tests are unchanged. Builds on PR 1 (host
workingTuning) + PR 2 (instrument->chart routing).

Tests: tests/js/tuner_auto_open.test.js — +2 (both-directions coverage via a live
Drop-D working tuning; publish-on-clear targets the right instrument slot); 29
pass total.

* fix(tuner): transactional open + fail-closed auto-open config (tuner-E #655 review) (#681)

Two review fixes for the auto-open opt-in+persist stage:

- enable() wasn't transactional. The panel (with the ×/Skip buttons) is shown
  before `await _tunerAudio.start()`, and `_state.enabled` was only set after it.
  A ×/Skip dismiss during that await hit disable() with wasEnabled=false, then
  enable() completed and flipped enabled on — an enabled-but-hidden zombie. Guard
  the open with an `_openGen` token bumped on every enable()/disable(); after the
  audio-start await, bail if superseded instead of enabling. Closes #675.

- Config wasn't fail-closed. routes.py normalized the opt-in with
  bool(data.get("autoOpenOnTuningChange", False)), so "false"/"0"/junk coerced to
  True. Accept only a real JSON boolean. Closes #676.

Tests: tuner_auto_open.test.js (dismiss-mid-open stays disabled — fails without
the token guard), test_config.py (auto-open default-false + fail-closed on
non-bool). 34 JS + 24 config tests green.

* fix(tuner): coverage stays conservative when the instrument is unknown (tuner-E #656 review) (#682)

_playerTuning() is documented as conservative ("missing data → not covered → still
prompt"), but when /api/settings carried no instrument identity (a fresh profile:
_default_settings() omits instrument/string_count/tuning) it invented guitar/6/440/
standard, so an unconfigured player was treated as 6-string E-standard and coverage
suppressed the auto-open (and badge cue) for matching songs. The post-#660 rewrite
only returned null when the whole fetch failed (!s), not when settings existed but
lacked an instrument.

Now return null unless there's a confident identity — any of instrument/string_count/
tuning in settings, or live working-tuning offsets. A configured standard guitar still
covers a standard song (no regression). Closes #677.

Tests: tuner_auto_open.test.js — empty-settings → not covered (fails without the fix);
configured standard guitar → still covered.

* fix(tuner): badge coverage cue staleness + unknown-as-warning + dedupe (tuner-E #657 review) (#683)

Three review fixes for the passive "different tuning" badge cue stage:

- Stale async cue (#678): _refreshCoverageCue awaited coverageReport then wrote the
  DOM unconditionally, so a slow /api/settings fetch could restore the previous
  song's amber ring after song:loading / leaving the player. Add a monotonic token
  bumped on every refresh and both clear paths; apply the awaited report only if the
  token still matches.

- "Unknown" rendered as "needs retune" (#679): the plugin returns a conservative
  all-false report on a fetch hiccup; the cue painted that as an amber "retune the
  reference pitch" ring. Collapse a no-signal report (not covered, no reference /
  retune / cantCover) to null (no cue) via _meaningfulReport(). A genuine not-covered
  report always carries reference / retune / cantCover, so real cues are preserved.

- Duplicate /api/settings fetch (#680): the auto-open gate and the badge cue both
  call coverageReport() per song:ready. Cache the coverage promise per song (keyed by
  session + tuning + centOffset) so they share one fetch; invalidate on song:loading,
  instrument:changed, and working-tuning-changed so it can't go stale within a song.

Tests: tuner_auto_open.test.js — concurrent reports share one fetch, a new song
refetches (fails without the cache). 34 JS tests green. Codex-reviewed.

Tuner auto-open: instrument-coverage check (issue E, stage 2/3) (#656)
With the opt-in auto-open on, only prompt when the player's current
physical tuning doesn't already cover the song. FeedBack is tune-to-song
(the highway draws tab in the song's tuning), so the check aligns the
song's open-string tuning string-for-string against the player's
instrument:

- An 8-string F# player gets no prompt for a 6-/7-string standard song
  (its top strings already match those tunings).
- A song needing an open string the player lacks (e.g. a Drop-A
  7-string's low A on an F# 8-string) still prompts.
- A whole-instrument reference difference (A440 vs A432, or an
  octave-down centOffset, previously ignored) also prompts.

Reads the player's instrument from core /api/settings (the v3 instrument
selector, a stable physical reference); conservative fallback (prompt)
when undeclared or unavailable, so a real retune is never silently
skipped. v3-only. All in plugins/tuner/screen.js; no core changes.

Stacked on #655. Follow-up E1.6: a passive badge cue that names the
strings to retune, plus splitscreen / no-usable-input guards.

Fix tuner auto-open flash: opt-in + persist (issue E, stage 1/3) (#655)
The tuner self-closes on song:play; autoplay fires it right after a song
switch, so an auto-opened tuner flashed shut ~1s later. An arrangement
switch (which never arms autoplay) instead persisted — the opposite
tester reports, and not the mic.

- New opt-in setting autoOpenOnTuningChange (tuner Settings, default OFF)
- An auto-opened tuner persists: it ignores the autoplay song:play, stray
  outside-clicks, and same-screen re-emits, closing only via the new
  in-panel x / Skip buttons or leaving the song. A manual open keeps the
  classic click-away / play-to-close behaviour.
- Adds the panel's first in-box close (x + contextual Skip).
- All in the tuner plugin; no core app.js changes.

Default (opt-in vs opt-out) is teed up for Byron to flip one boolean.
Staged follow-ups: E1.5 = instrument-coverage smart prompting + badge
cue; E2 = holdAutoplay gate.

Tests: tests/js/tuner_auto_open.test.js (opt-in gate, persist mode,
play/click-proofing).

095d718b85 Address review: Reset on All restores defaults verbatim
The Reset handler forced base.enabled = true after copying _ASPECT_DEFAULTS
(where enabled is false) — a leftover from when enabled controlled panel
visibility. Visibility is now independent (Shift+A / ×), so drop the override
and let Reset restore the defaults exactly.
