adminandClaude Opus 5.5 fe4e0d9f1a Snap to the grid from the start in every graph tab (#391)
game-maker / gate (push) Successful in 4m12s
game-maker / suite (push) Successful in 15m55s
Laying out a graph by hand mostly means lining nodes up, so the
magnet was switched on in nearly every session. Every graph tab now
starts with it lit: Behavior, State machine, Shader, Particles,
Sound FX, Instrument, the song's Routing and the Routing tab.

- SnapToggle takes the state it starts in and lights its button to
  match. GRAPH_SNAPS_AT_FIRST sets it for the toggles and for
  GraphCanvas alike, so button and canvas cannot disagree.
- Curve and Vector Art are no graphs and still start without it.
- New hook __gm.graphSnapping(on?) reads every graph tab's magnet,
  or "mixed" where button and canvas differ, and switches them all.
- The e2e harness reads the magnets after each navigate() and then
  switches them off, as it already sets the zoom transition to 0.
  Most checks drag a node to an exact spot. e2e 45 does the same
  itself, because the editor comes up there through the sign-in.
- e2e 06 checks that all eight graph tabs started with the magnet on.
  The checks in 06, 26 and 65 that read it off now say they read
  what the harness left.

Tests:
- Unit snap-toggle: 4 tests, 1 new (lit at first, nothing asked of
  the target before a click).
- e2e 06 (melektaus-atx): 150 checks, 1 new. e2e 34: 134 checks.
- Gate (melektaus-atx, together with #390): 287 files, 4397 tests.
- Pictures looked at: none, the state comes from the hook.

adminandClaude Opus 5.5 25084f8576 Refactoring round 10: split SoundLibrary, fold sound duplicates (#85)
game-maker / gate (push) Successful in 4m3s
game-maker / suite (push) Successful in 14m52s
Refactoring round 10 covers everything since round 9 (808e1ee): 110
commits with about 47 000 new lines, nearly all of them sound, sound
FX, instruments, patterns and songs. Behaviour is unchanged.

Duplicate code (jscpd over src, 50 tokens, TypeScript only, measured
on 808e1ee and here alike: 47 clones / 426 lines before, 33 / 245
after; round 9 itself ended at 22 / 160 by this count):

- PreviewParams (new, editor/soundfx) is the header's parameter bar
  of the Sound FX and the Instrument tab: values, defaults, fields
  and the voices a moved field reaches. Both tabs had it line for
  line.
- fxWorklet: an Effect base runs the bit crusher, phaser, flanger,
  limiter, LFO and bus shifter, a Source base the pitch player and
  the Chip. Start is the one wait for a voice's first sample, which
  four processors wrote out each.
- nodes/shared has checkPort, detachedPort, fxParamsPort and
  letRingPort. The Play and Stop nodes of sounds, notes, patterns and
  songs spelled each port out, up to five times.
- parameterValues builds both Sound FX parameters and Instrument
  parameters, which differed in name and text only.
- SetLoopCommand sets the ruler loop of a pattern or a song. It
  replaces SetPatternLoopCommand and SetSongLoopCommand.
- addLink in music/routing is the one rule for a link that both the
  song routing and the Master routing keep.
- eqCurves works out each band and their sum for the EQ tab, which
  did that in its drawing code. It replaces eqCurveDb, which only a
  test called.
- Smaller ones: the eight neighbour directions of a tile cell, and
  drawFloatingBox for the shadowed box of Popup and FloatWindow.
- Left on purpose: Play pattern and Play song stay two parallel node
  definitions, and the smaller clones under ten lines stay.

Architecture:

- SoundLibrary.ts goes from 2897 to 2188 lines. What a stage of a
  sound FX becomes as Web Audio nodes, and how the knobs of a playing
  voice move, is now viewport/fxNodes.ts. None of it keeps state of
  the library.

Dead code (TS language service, references per export and member):

- soundRefIds, LFO_SHAPE_INDEX, TREMOLO_ROWS, VIBRATO_ROWS and
  REVERB_ROWS had no reader. The four routing node defs are
  registered without an unused exported name.
- soundFileOf and portTypeOf were called by tests only. The tests
  now ask findSound and portOf, which the editor uses. DRY moves
  from src into the one test that uses it.
- 51 values used only in their own file lose their `export`. Types
  and the node catalogues stay exported.
- Kept on purpose: neighboursOf is the cell by cell reading the
  indexed neighboursIn is checked against, and PitchShifter.latency
  is the test's one view of how late the shifter is.

Comments and docs:

- Seven comments told history ("no longer", "any more", "as
  before", "of before #354"). Nine comment blocks ran far past the
  line width. Proof that this changed no code: the bundle was md5
  identical, and the touched tests and e2e modules were identical
  after esbuild.
- README: sound FX, instrument, pattern, song and bus in the asset
  list, the pages Instruments, Patterns and Songs, 1919 checks.
- Wiki: see its own commit.

Tests:

  Gate (melektaus-atx)    274 files, 4236 tests, CHECK EXIT 0
  e2e 34, 64, 65          ALL PASSED, 180 checks
  Unit, touched areas     16 files, 804 tests

No check was added, the e2e sum stays at 1919. Counter-checks, each
put back by copy and compared with cmp:

- addLink without the loop rule: 2 tests fail, one per routing.
- eqCurves with the sum of the last band only: 1 test fails.
- Start in the worklet never waiting: e2e 34 fails in exactly the
  four checks that hang on a voice's first sample (Flanger, Tremolo,
  Chip, a pitched note planned ahead).

adminandClaude Opus 5.5 af2312a5e7 Play every tab's preview straight into the master (#368)
Since #351 the tabs played their asset along its links in the Master
routing, as the game does. A song linked into a reverb bus was heard
through that bus while it was edited. A preview should sound like the
asset itself, so the tabs leave the Master routing out again.

- The Sound, Sound FX, Instrument, Pattern and Song tab play into the
  master. The sound FX of the asset still applies, and so does the
  master's own volume and FX.
- Inside a song its own routing of tracks and sends still counts.
- The game is unchanged: Play nodes go along the routing as before.

Tests:
- e2e 34 (melektaus-atx): ALL PASSED, 96 checks. The routing check
  now holds the mix of the two buses as before, and the Sound tab on
  the master with the bus silent.
- Counter-probe e2e: the Sound tab along the routing again, the
  routing check red.
- Gate (melektaus-atx): CHECK EXIT 0, 274 files, 4230 tests.

adminandClaude Opus 5.5 0e73fd85b9 Route sounds, songs and buses in one Master routing graph (#351)
game-maker / gate (push) Successful in 4m20s
game-maker / suite (push) Failing after 15m17s
A project bus could only go into one other bus, and a sound, an
instrument, a pattern or a song into exactly one bus. A shared reverb
needs a sound to go there in part and on dry at the same time. Instead
of a list of sends on every asset, the project gets one routing graph
like the routing of a song (#350), one level up.

- Menu -> Master routing opens a tab with one graph per project. It has
  a node per sound, instrument, pattern, song and bus, named after its
  asset, and one Master. Embedded assets have none, their song routes
  them.
- The nodes follow the assets. Every edit settles the routing in the
  same undo step (KeepRoutingCommand), so an undone delete brings the
  links of its asset back. A new asset gets a node and a link to the
  master. What went only into a deleted bus goes to the master.
- New nodes start in three columns: what plays, the buses, and the
  master a row above, so no link into it runs behind a bus.
- Links are sends: -60 to +12 dB, and a Mode on links out of a bus or a
  song. Out of a sound, an instrument or a pattern a link always takes
  the sound after its volume and FX. Loops are refused.
- A node without a link is silent and says "Goes nowhere".
- The rows Bus and Into are gone. Play nodes with a picked bus still
  overrule the routing.
- A click on a node shows its asset in the inspector, the Master shows
  the master volume and sound FX. A double click opens the asset's tab.
- The graph lives in project.routing and is held to the assets when a
  project is read, but nothing is added there. The editor adds the
  nodes when it opens a project. An asset without a node plays on the
  master, so old projects sound as before without a migration.
- In the mix an asset with one link at 0 dB goes straight into that bus.
  A sound or instrument with more gets a bus of its own with the sends.
  A pattern or song sends from the master of its playing, which is
  where its Mode taps. Buses of the mix can have sends now too.

Found:

- The check "the scheduler plans a looped bar" in e2e 34 wobbles. It
  failed in 2 of 5 runs here and in CI task 580 at 490fcba, before
  this change. HEAD passed it 2 of 2. Not fixed here.

Tests:

- Unit master-routing (new, 10), sound-library (2 new), buses
  rewritten onto the routing, 5 lists without the Bus row. 5 counter
  checks red.
- e2e 34 (melektaus-atx): ALL PASSED, 93 checks (3 new, 2 rewritten).
  Counter check with the Sound tab ignoring the routing: the routing
  check red.
- Gate (melektaus-atx): CHECK EXIT 0, 273 files, 4225 tests.

adminandClaude Opus 5.5 42a3759d9d Cut a sound into named clips, as a texture into frames (#357)
A sound could only be cut to one stretch, set on the asset itself. To
play two parts of one file, the file had to be imported twice. Now a
sound is always the whole file, and its clips are the stretches of it,
each with a name and a cut of its own.

- A clip is { id, name, props } on SoundAsset.clips. Its id shares the
  generator with asset ids, so a sound field holds a sound or a clip,
  as a texture field holds a texture or a frame.
- props are the cut: start, end, the fades and their curves, reverse.
  Volume, loop, sound FX and bus stay on the sound for all its clips.
  The cut rows left the sound's schema for CLIP_ROWS.
- findSound resolves either id. Play sound, the Sample of an
  instrument, a Reverb impulse, song items, the scheduler and the test
  sound of the Sound FX tab all go through it.
- Every sound field offers each sound followed by its clips, "Kick",
  "Kick / Clip 1". A clip that is gone reads as "<id>?".
- The Sound tab has a strip under the ruler with the clips as bands.
  A drag there makes a clip, a click picks one, beside the bands the
  sound. Only the picked clip has handles. Reverse, fades and curves
  in the header work on it and are greyed out without one.
- Whole file is gone from the header, as the user asked.
- Picking a clip is a selection of its own, like a frame. The
  inspector shows its name, its cut rows and Delete clip. Delete
  takes it away without asking, as with a frame. Ctrl+Z brings it
  back.
- Copies get fresh clip ids: Duplicate, Embed a copy, a song
  duplicated with its takes, and the copy a split or paste makes of
  an embedded take. An item on a clip plays the same clip of its copy.
- A double-click on a song item playing a clip opens its sound with
  the clip picked. The Sound row of an item on an embedded take
  offers the take and its clips, which no list shows.
- A new take stays the whole sound. Clips are made by hand, as the
  user decided.
- No migration in the code, as the user decided. The one project
  with cut sounds was changed over by hand.

Deviation from the issue: deleting a used clip does not warn. A frame
does not warn either, and the issue had promised "like a frame".

Tests:
- Unit sound-clips (new): 11 green, 7 counter-checks each red
- Unit sounds, embedded: adjusted to clips, green
- e2e 34 (melektaus-atx): ALL PASSED, 90 checks (3 new, 12 rewritten)
- Counter-check in the browser: clips left out of the sound fields,
  the picker check fails
- Gate (melektaus-atx): CHECK EXIT 0, 271 files, 4194 tests

adminandClaude Opus 5.5 25c1d02b06 Keep the audio thread free of ended voices and too many vocoders (#356)
game-maker / gate (push) Successful in 3m45s
game-maker / suite (push) Successful in 14m44s
A song that had been played a few times in a long session stuttered
at regular intervals until the page was reloaded. A quick run up the
keys of a sampled instrument made every sound drop out for a second
or two. Both came from work the audio thread should not have had.

- Every worklet node of a voice listened on its port. Chrome never
  collects a port that is listened to, and through its listener not
  the voice either. Every node of the voice stayed on its bus and was
  worked on in every block. A way or stage on the worklet now closes
  its port once it ends or is stopped, and the processor closes its
  own side when it is told to stop.
- A voice without echoes now leaves its bus as soon as its sound and
  what its stages hold back are through. Before, only a voice with
  echoes did.
- At most 12 ways play through the pitch worklet at once. One more
  cuts the oldest in 10 ms, a note already let go before one still
  held. Each runs a phase vocoder, whose first block alone took
  2.7 ms of the 2.67 ms a block has on stein2.
- Play for the game ends everything the tabs play: the piece holding
  the transport and every key or preview (`stopPreviews`).
- Closing a Sound, Sound FX, Instrument, Pattern or Song tab stops
  what it plays of that asset (`AssetTabEditor.closed`).
- A preset in the Instrument tab plays nothing any more. With
  Audition on it is heard like any other change.
- Test hooks: `__gm.instrument.play`, `__gm.sound.playing`, and
  `vocoders` in the stats of the sound library.

Measured:
- A copy of the project, its Song 2 played for 12 s and stopped, six
  times (Chrome on stein2, CDP WebAudio): before, 746 nodes were left
  after the first time and 4469 after the sixth, the load at rest
  grew from 0.01 to 0.06. After, 7 nodes are left every time (the
  master and one bus) and the load at rest stays at 0.01 to 0.02.
- Pitch-player voices live in Chrome on melektaus-atx: 12 take 0.50
  of the audio thread, 16 take 0.71, 24 take 0.99. 30 struck 40 ms
  apart held it at 0.99 from the first second on.

Tests:
- Unit sound-library: 110 green (3 new), 4 counter-probes each red
- e2e 34 (melektaus-atx): ALL PASSED, 86 checks (3 new, 2 changed)
- e2e counter-probe with game start and preset undone: their 3
  checks red, and the old check of Play note in the game as well,
  which now counts on the preview being gone
- e2e counter-probe with tab close undone: exactly its check red. A
  first form of it held a key and stayed green, since the keys let go
  of a held key by themselves once the tab shows no asset
- Gate (melektaus-atx): 270 files, 4181 tests

adminandClaude Opus 5.5 23cb34f781 Keep a recorded take inside its song (#355)
A take used to land in the Assets panel as "Song – Take N", next to
every other sound of the project. Now a song can keep a sound, a
pattern or a sound FX to itself: an ordinary asset whose new field
`owner` names the song. Everything that finds an asset by its id
finds it, so playing, the tabs and the game need no change. Only
the places that list assets leave it out.

- `core/music/embedded.ts` holds the rules: which types can be
  embedded, `listedAssets`, the title "Song › Take 1", and the
  rows an embedded sound hides (Loop, Bus).
- One user per embedded asset. `SetSongCommand` settles the song
  after every edit: a place naming an asset an earlier place
  claimed, or one of another song, gets a copy, and what nothing
  names any more goes in the same undo step. The outcome is worked
  out once, so a redo brings back the same copies.
- A split, Ctrl+D and a paste get that for free. The clipboard
  keeps the embedded assets of the copied items, so a paste after a
  delete brings the take back.
- Deleting a song deletes what it keeps. Duplicating it copies
  that and points the copy at the copies. A duplicate of an
  embedded asset is a project asset.
- The item menu has Open, Make project asset and Embed a copy.
- An embedded item carries a bullet in front of its name. The
  first pick was a diamond, which the gate's font test refused:
  the UI font has no glyph for it.
- A take is "Take 1", 2, … numbered per song. With the song gone
  while it uploads, it becomes a project sound under a free name.
- Left out of: the Assets panel, every asset picker, the sound FX
  menu of a track, the test sound of the Sound FX tab and the
  naming of new assets. Delete on an embedded asset only says
  where it lives. A ping lights up its song.
- Loading drops an `owner` whose song is gone, the asset stays as
  a project asset. No migration: older projects have no owner.

Tests:
- Unit embedded (new): 13 green, 6 counter-checks each red
- Unit take, song, song-edit, asset-fx, asset-ref, serialize and
  neighbours: 116 green
- e2e 65 (melektaus-atx): ALL PASSED, 47 checks (1 new)
- Counter-check e2e 65 (asset panel unfiltered): exactly that
  check red
- Gate (melektaus-atx): CHECK EXIT 0, 269 files, 4167 tests

adminandClaude Opus 5.5 d349251a01 Put a sound in a room, a hall or a cave with a Reverb node (#328)
game-maker / gate (push) Successful in 4m0s
game-maker / suite (push) Failing after 13m51s
A sound FX had no space around it. The Reverb node folds the sound
with an impulse response: one it makes itself, or a sound asset as the
answer of a real space. It works on a voice and on a bus.

- Type: Room, Hall, Cave and Plate have fixed numbers. Custom shows
  Decay (up to 10 s), Damping and Pre-delay. Sound shows the pick of a
  sound asset and Pre-delay. The rows are derived ports, the sound pick
  an idle param, so they only appear for their type.
- The made impulse response is seeded noise per side, 60 dB down at
  Decay, through a low-pass closing from 20 kHz toward 500 Hz as far
  as Damping says. It is made once per rate, decay and damping, the
  last 16 are kept.
- A sound as impulse response: the sound FX compilers now get the
  project, so a node can turn a sound asset into its file. The build
  key holds that file, so a cut or swapped sound builds again. The
  instrument compiler does the same for a Reverb inside an instrument.
- The library loads that file with the voice, a sequence or before a
  bus builds its chain. A missing file leaves the reverb silent.
- Mix blends dry and reverb and is the only number that moves while
  the sound plays, as the issue said. The voice rings for pre-delay
  plus decay, or as long as its sound.
- The open point from #325 about sends on project buses is #351, not
  part of this.

Tests:
- Unit reverb (new) 4, soundfx 57 (4 new), sound-library 104 (2 new),
  green.
- Counter-checks, each turns one test red: the impulse file not loaded
  with the voice, the tail without the length of the sound.
- e2e 34 (melektaus-atx): ALL PASSED, 81 checks (1 new). Chrome
  offline: silent during the pre-delay, 35.9 dB fall over 0.6 s of a
  1 s decay (36 expected), the dry half at 0.25 for mix 0.5. A sound
  with one sample at 0.2 s gives the impulse back 0.25 s later and
  nowhere else.
- Gate (melektaus-atx) over the end of this series #318 to #328:
  CHECK EXIT 0, 267 files, 4134 tests.

adminandClaude Opus 5.5 3a52f2290f Mix sounds through buses and a master (#325)
game-maker / gate (push) Successful in 3m36s
game-maker / suite (push) Failing after 14m30s
Until now every sound went straight to the speakers. There was no
point where all of them came together, so nothing could turn the
music down against the effects, and a compressor or a shared echo
over everything had nowhere to sit. The bus technique of #346 was
there already, only the end of the chain was missing.

- Bus asset (Audio): Volume, Sound FX and Into. Into is empty for
  the master and never offers the bus itself nor a bus that already
  goes into it. The list is worked out when the menu opens, so a
  change made meanwhile counts. A loop that is in a project anyway
  sends the buses on it into the master.
- The master is no asset. Its volume and sound FX are two new rows
  under Master in Project settings, one undo step each. A project
  written before has 1 and none, which is how it sounded.
- Sound, instrument, pattern and song have a row Bus, empty for the
  master. Play sound, Play note, Play pattern and Play song have an
  input bus: From the asset, Master or a bus. Inside a song or a
  pattern only the bus of the song or pattern counts.
- Set bus volume (bus, volume, time, easing) and Bus volume. An
  empty bus is the master. The volume set holds for the whole run,
  across scenes, over that of the asset. GameRun resets it at start
  and end. Set sound FX parameters without a voice now reaches the
  sound FX of the bus picked in its new bus input.
- SoundLibrary: the master is the bus "mix", each bus "mix:<id>".
  Every bus, the playing masters of #346 included, ends there, and
  only the master is heard. setMix sets them up once a context
  exists, so an editor nobody listened to opens no audio device. The
  same mix again changes nothing, which lets the editor hand it over
  on every change of the project.
- The tabs play as the game does: Sound, Sound FX, Instrument,
  Pattern and Song tab through the bus of their asset and the master.
- Pause game does nothing to the buses (the user's answer 4b). A
  game that wants quiet in its pause menu sets a bus volume itself.
- Streaming long music files is #349, split off as asked.

Finding on the way: the Into menu first worked from a list made when
the inspector row was built. After another bus was sent into the
open one, e2e 34 saw it still offered. It is now asked on open.

The SoundLibrary tests expected voices to end at the destination.
They now end in the master, which adds its input, level and pan to
every wiring and two gains to every list. Those expectations are
updated, nothing else in them changed.

Tests:
- Unit buses (new): 15 green. Ten counter-checks, each red on its
  own: loop check, bus picked, reset at run start, bus of Set sound
  FX parameters, master volume in the settings, and in SoundLibrary
  default into the master, voices into the master, run volume over
  the mix, no context before a play, a playing on its bus.
- Unit sound-library: 90 green (5 new). Node catalog: 416 green
  (9 new cases).
- e2e 34 (melektaus-atx): ALL PASSED, 75 checks (3 new). The voice
  of the Sound tab was heard on mix:<bus>, that bus into the other,
  that one at 0.5 into the master. Master volume 0.6 via the dialog,
  undo back to 1.
- Gate (melektaus-atx): CHECK EXIT 0, 262 files, 4072 tests.

adminandClaude Opus 5.5 f1f4a57589 Cut a sound to a stretch of its file in its own Sound tab (#343)
game-maker / gate (push) Successful in 3m32s
game-maker / suite (push) Failing after 18m20s
A sound asset now opens in a tab that shows its file as a waveform.
Two handles set where the sound starts and ends in the file, and that
stretch is the sample: Play sound, a song item and an instrument's
Sample all play it and nothing else. The file itself is never changed.

- The asset has three new rows: Start (s), End (s) and Edge fade (ms).
  End 0 is the end of the file, the fade is 10 ms by default. Older
  assets have no values and play the whole file as before.
- Every way of playing asks playedSoundOf() for a name instead of the
  file: the file, or <file>#<start>~<end>~<fade> for a cut.
- SoundLibrary makes the cut from the decoded file the first time that
  name plays and ramps each edge inside the file over the fade. Length
  and peaks of a cut are read from the file without a copy.
- Cut buffers can be made again at any time, so the library lets the
  oldest go past 64 Mi samples. A voice holds its buffers itself.
- The tab draws min/max per pixel from 256-sample block peaks, and the
  samples as a line when zoomed in far. Wheel zooms, the middle button
  pans, as in the music tabs. Wave, cut and ruler sit under a mask,
  so a handle panned out of view does not draw over the panels beside.
- Dragging a handle moves that edge, dragging elsewhere spans a new
  stretch. One drag is one undo step for both edges. Whole file puts
  the handles back, Play or Space plays the stretch with a playhead.
- The inspector preview and the Sound FX preview play the cut too, and
  the song lanes draw and repeat it.

Tests:
- Unit: sounds 20, wave-view 8 (new), sound-library 68, plus 258 in
  the touched areas (instrument, song, pattern, inspector, tabs)
- e2e 34 on melektaus-atx: ALL PASSED, 57 checks (7 new)

adminandClaude Opus 5.5 c7e9769f90 Change the sound FX parameters of a sound while it plays #315
game-maker / gate (push) Successful in 3m14s
game-maker / suite (push) Successful in 15m39s
Until now a value handed to a sound FX counted from the start of the
voice only. An engine whose pitch follows the speed, or a loop that
gets quieter, could not be built. Every play of Play sound now gives
out the number of its voice, and a new node lets the knobs of that one
voice glide to new values while it plays.

- Play sound has a new output voice: the number of this one play, or 0
  where nothing was played. Kept in a Number variable it reaches the
  voice from another event. Two plays of one sound are two voices.
- New action node Set sound FX parameters (exec, voice, fx params).
  It reaches exactly the voice it is given, a detached one too. A
  voice that has ended, or voice 0, is not reached.
- AudioSink.play returns the voice number and takes the plan and the
  values (FxVoice) instead of a finished chain. AudioSink.tune takes a
  voice number and new values. A name the voice's FX does not have is
  left out, one not given keeps its value.
- SoundLibrary hands out the number at once, before the bytes are
  there, and never twice. A voice still waiting for its bytes starts
  with the values handed in meanwhile.
- Every knob of a voice moves with setTargetAtTime (30 ms time
  constant). A knob whose value did not change is not sent again, so a
  tune every frame costs next to nothing.
- A pitch on a playing voice glides by playbackRate. A new WSOLA copy
  in the middle of a sound is not worked out, so the voice gets shorter
  or longer while it is moved. On a loop that is not heard.
- fxChainOf now gives a chain whose shape depends on the plan alone.
  A stage fed by a parameter stays at 0 dB, and a Mix fed by a
  parameter keeps both ways. A typed-in 0 or Mix at 0/1 is still left
  out by the compiler.
- Every way of a voice has a source of its own, also at the same
  pitch, so each can glide on its own. The pitched copy is shared.
- The tab keeps the numbers of what it plays, so moving a parameter
  field is heard at once.
- Test hook __gm.sound.levels(file) reads the knobs of every voice of
  a file, oldest first, and stats() counts the voices tuned.

Tests:
- soundfx.test.ts: 29 tests (+2 for the node in a running world: the
  voice of the first of two plays of one sound, and a play that played
  nothing)
- sound-library.test.ts: 15 tests (+3: glide, reach by number,
  pending voice)
- node-catalog.test.ts: 370 tests (+2, Play sound checks its voice)
- sounds + keep-on-scene-load: 31 tests, unchanged
- Counter-test: a tune that reaches every voice of the same file makes
  the reach test fail.
- e2e 34 (melektaus-atx): ALL PASSED - 30 checks (+1). In Chrome two
  looping voices of one sound start at depth 7. The one whose number
  sits in a variable glides to 0.7938 (2^(-4/12) = 0.7937), the other
  stays at 1. Both gains stay at 0.5012.
- The gate ran before voices got a number (CHECK EXIT 0, 241 files,
  3658 tests), not after.

adminandClaude Opus 5.5 183f356c99 Let a game hand values to the parameters of a sound FX #311
game-maker / gate (push) Successful in 3m10s
game-maker / suite (push) Failing after 14m15s
A sound FX played the same every time: its numbers were settings of
the nodes. Now the Input declares parameters with a default, every
number of Gain, Pitch and EQ is an input they can feed, and a Play
sound hands in values for them.

- Input declares number parameters in the inspector, each with a
  Default (DeclaredPort.default, SetPortDefaultCommand). They are
  outputs of the Input. Input and Output count as terminals now, one
  of each per graph.
- Gain, Pitch and EQ take their numbers at inputs under the keys the
  settings had, so saved graphs sound as before without a migration.
  Each value is held to its range however it arrives.
- The compiler gives an FxPlan with the parameters still open.
  fxChainOf fills them in when a voice starts. The player still only
  sees an FxChain.
- New behavior node Sound FX parameters: names an FX and picks its
  parameters like a Variables node picks variables. Each picked one is
  a number input that starts at the FX's default. Its output has the
  new port type fxparams, which only fits Play sound's fx params.
- Play sound warns when the parameters name another FX than the one
  it plays. Names the FX does not know are left out.
- Renaming a parameter at the Input renames it in every Sound FX
  parameters node naming that FX, edges and values included.
- The Sound FX tab has a number field per parameter in its header.
  Play uses those values, they are never written into the asset.
- A value counts from the start of a voice. Changing a playing voice
  is #315, a Mix node is #316.

Tests:
- soundfx.test.ts 22 (+11): parameters in the plan, held values, a
  0-by-default stage, EQ band, save with defaults, wrong port types,
  default command with undo, Sound FX parameters into Play sound,
  defaults of picked ones, node problems, mismatch, rename with undo
- node-catalog 368 (+3): Play sound fx params, Sound FX parameters
- e2e 34: ALL PASSED - 28 checks (+2: header field plays depth 5,
  a Sound FX parameters node gives the game's voice depth 7)
- Gate on melektaus-atx: typecheck, lint, prettier clean, 240 test
  files, 3636 tests green
- Counter-check: with fxChainOf ignoring the values and the rename
  not followed, 5 of the new tests fail.
- Browser probe: header fields, inspector Default and the picked
  parameter looked at in two screenshots.

adminandClaude Opus 5.5 de14f0f9e2 Play a sound through a graph of gain, pitch and EQ effects #311
A sound could only be played as it was uploaded. A Sound FX asset is
a node graph like a shader: Input, effects, Output. Play sound has a
new input fx that sends the voice through it.

- New asset type soundfx ("Sound FX"), not placeable, with a graph
  and its own tab. The heading in the asset panel is "Sound effects",
  so it does not take the click meant for the + menu entry.
- Nodes in core/soundfx/nodes.ts, category sound, port type audio
  that only fits audio: Input, Output, Gain (dB), Pitch (semitones),
  EQ (80 Hz and 12 kHz shelves, peaks at 250 Hz, 1 kHz and 4 kHz).
- compileSoundFx walks back from the Output with the shared graph
  emitter. An input takes one edge, so the result is one line: a
  pitch and a list of gain and filter stages. A node without input
  or a graph without Output reports a problem on the node.
- Pitch is the playback rate of the source. It applies to the whole
  sound and also changes its length, the node description says so.
- The BehaviorSystem resolves fx and hands the line to the AudioSink.
  An fx that is missing or does not compile plays the sound dry.
- SoundLibrary wires source, stages, volume, destination in that
  order. stats().last now also names pitch and stage count.
- The tab header picks one of the project's sounds and plays it
  through the graph as it stands. Stop there ends only its own voice.

Tests:
- soundfx.test.ts (new, 11), sound-library (9, +2 for the wiring),
  node-catalog (+1 for fx), graph and asset-groups adjusted
- e2e 34: ALL PASSED - 26 checks (+5: + menu opens the tab, palette,
  2 effects, tab Play and game Play through the FX at -12 st)
- Gate on melektaus-atx: typecheck, lint, prettier clean, 239 of 240
  test files green. The red one was sound-library (its fake
  AudioContext had no playbackRate), fixed afterwards, gate not
  re-run in full.
- Counter-check: without the audio rule in portsCompatible the port
  test fails.
