123-129: BPM sync effect may conflict with polling.This
$effecttracks both$transportStore.bpmand the localbpm(read in the comparison). The 30Hz polling on line 137 continuously overwritesbpmwithTransport.bpm, which re-triggers this effect each time.

131-151: Polling-based sync — consider documenting the trade-off.Two
setIntervaltimers (30Hz + 1Hz) are used to sync state fromTransportandAudioServiceinto Svelte reactive state.

In `@docs/design-docs/specs/77-global-transport-control.md`:
- Line 643: The "Completed: 2024-02-24" date is a typo; update the completion
date string to "Completed: 2026-02-24" in the docs entry so the record matches
the PR creation date (search for the literal "Completed: 2024-02-24" to locate
and replace it).
- Around line 580-591: The docs list TimeDisplay.svelte in the "Files to Create"
table but the implementation was folded into TransportPanel.svelte; update the
spec to either remove `src/lib/components/transport/TimeDisplay.svelte` from the
planned files or add a note that its time-display logic was inlined into
`TransportPanel.svelte` (and update the "Files Created" table accordingly) so
the tables match the actual code structure.
In `@ui/src/lib/canvas/shadertoy-draw.ts`:
- Around line 123-126: The iTimeDelta uniform currently computes delta as
(props.transportTime - props.lastTime), which mixes transport and local clocks
and yields 0 when transportTime falls back; change it to compute the difference
between the current transportTime and the previous transportTime supplied by the
renderer (or tracked separately). Update the uniforms provider for iTimeDelta in
shadertoy-draw.ts to accept a previousTransportTime/prevTransportTime (from the
renderer props or an internal prevTransportTime field) and return
(props.transportTime - props.prevTransportTime) (or 0 if prevTransportTime is
undefined), ensuring you do not reference lastTime for this calculation; keep
iTime and other uniforms unchanged.
In `@ui/src/lib/components/BottomToolbar.svelte`:
- Around line 180-182: The Trash2 icon in BottomToolbar.svelte currently uses
Tailwind class text-red-400 which violates the Zinc-only palette guideline;
update the icon's color class to a Zinc dark-theme color (e.g., replace
text-red-400 with the appropriate Zinc class used across the app) on the button
that calls handleDelete and ensure the destructive buttonClass styling remains
consistent with Zinc palette usage for the BottomToolbar component.
- Line 103: The module-level access to navigator when defining const isMac in
BottomToolbar.svelte will crash during SSR because navigator is undefined; fix
by guarding the access (e.g., compute isMac only if typeof navigator !==
"undefined") or move the detection into a client-only lifecycle (onMount) and
store the result in a reactive/local variable used by the component (referencing
isMac and BottomToolbar.svelte to locate the change).
- Line 34: The import line in BottomToolbar.svelte brings Play and Pause from
'@lucide/svelte/icons'; change it to import them from the main package
'@lucide/svelte' to match project conventions. Update the import that references
the named symbols Play and Pause so the module specifier is '@lucide/svelte'
(keep the symbol names unchanged) to consolidate icon imports across the
codebase.
In `@ui/src/lib/transport/StubTransport.ts`:
- Around line 15-43: The seconds getter and play() are problematic: change get
seconds() to use ts-pattern's match(...) on this._isPlaying (importing match
from 'ts-pattern') instead of an if, returning pausedAt when not playing and
(performance.now() - this.startTime)/1000 when playing; make play() idempotent
by returning early if this._isPlaying is true (do not reset this.startTime) and
only set startTime = performance.now() - this.pausedAt * 1000 and _isPlaying =
true when transitioning from stopped to playing; reference the getters and
fields seconds, get seconds(), play(), _isPlaying, pausedAt, and startTime when
applying the change.
In `@ui/src/lib/transport/ToneTransport.ts`:
- Around line 62-70: Replace the if/else in setDspEnabled with a ts-pattern
match on the enabled boolean: import match from 'ts-pattern' and call
match(enabled).with(true, () => ctx.resume()).with(false, () => (ctx as
AudioContext).suspend()).exhaustive(); keep using
this.tone.getContext().rawContext for ctx and await the returned promise from
ctx.resume()/ctx.suspend() so the behavior of setDspEnabled remains identical.
In `@ui/src/lib/transport/Transport.ts`:
- Around line 38-42: play() can re-enter upgrade() when called concurrently;
change play() to use a single in-flight upgrade promise (e.g., add an
upgradePromise property) so multiple play() calls await the same upgrade instead
of spawning multiple ToneTransport instances, and replace the current if-check
with ts-pattern match logic: when !this.upgraded && !this.upgradeDisabled set
this.upgradePromise ||= this.upgrade() and await it, then clear the promise and
proceed to return this.impl.play(); reference the play(), upgrade(), upgraded,
upgradeDisabled, and upgradePromise symbols when applying the change.
In `@ui/src/workers/rendering/hydraRenderer.ts`:
- Around line 104-105: Guard assignment to Hydra's synth time so undefined
transportTime doesn't overwrite timing: in hydraRenderer (where
this.hydra.synth.time is set from params.transportTime) check that
params.transportTime is a valid number (e.g., !== undefined/null and typeof ===
'number') before assigning; if it's not present, skip the assignment (or fall
back to an explicit safe default) so existing this.hydra.synth.time is not
poisoned.

iTimeDelta now mixes transport and local clocks, yielding 0 or skewed deltas.
When transportTime falls back to lastTime, the delta is always 0; when transport is active, lastTime is still local time so delta reflects clock skew. Please pass a previous transportTime/transportTimeDelta from the renderer (or track it separately) and compute iTimeDelta from that value.

@lucide/svelte documentation icon imports entry point
💡 Result:
For @lucide/svelte, the documentation describes two import entry points:
-
Package entry point (named exports):
<script> import { Skull } from "@lucide/svelte"; </script>
[1]
-
Icon entry point (deep imports, recommended for faster builds/dev performance):
<script> import CircleAlert from "@lucide/svelte/icons/circle-alert"; </script>
[1][2]
Icon filenames use kebab-case (e.g. more-vertical, circle-alert). [2]
Sources: [1] Lucide Svelte package guide, [2] shadcn-svelte changelog (updated icon import guidance).

Make play() idempotent and switch to ts-pattern.
Line 40 resets startTime even when already playing; repeated play() calls can jump time. Also, Line 16 uses an if in a TS file, which violates the ts-pattern guideline.

Guard against concurrent play() calls re-entering upgrade.
If play() is called twice before upgrade() completes, you can create multiple ToneTransport instances and reset state. Line 39 also uses if instead of ts-pattern.

TransportButton.svelte and constants.ts missing from both the "Files to Create" and "Files Created" tables.
TransportButton.svelteis described as a first-class UI component in the spec (line 345–347), referenced in the toolbar integration section (line 573), and noted in the "Files Modified" table at line 669 (BottomToolbar.sveltewas changed to use it). The AI summary also confirms it was created. Yet it appears in neither the "New Files" plan table (lines 580–591) nor the "Files Created" status table (lines 647–657).src/lib/transport/constants.tsis explicitly planned in the "New Files" table (it exportsDEFAULT_BPMandDEFAULT_PPQ), but is absent from the "Files Created" table.
Both omissions leave the spec inconsistent with the actual implementation.

@lucide/svelte icons import path correct entrypoint v0.561.0
💡 Result:
For @lucide/svelte v0.561.0, the correct icon entrypoints are:
<script>
// Named export (works)
import { Camera } from "@lucide/svelte";
// Preferred deep import (faster dev/build): kebab-case icon name, default export
import CircleAlert from "@lucide/svelte/icons/circle-alert";
</script>Deep imports always use @lucide/svelte/icons/<icon-name-in-kebab-case> (default export). [1] (Shadcn-Svelte shows the same deep-import pattern, e.g. @lucide/svelte/icons/check.) [2]
Sources: [1], [2]
Use @lucide/svelte import path for icons.
The import path @lucide/svelte/icons is not a valid named export source. Per the library documentation, icons should be imported either as named exports from @lucide/svelte or via deep imports from @lucide/svelte/icons/<icon-name>. Switch to the documented named export approach:

Use ts-pattern for paused state branching and replace red-400 with zinc palette colors.
The paused state currently uses {#if} + ternary logic with text-red-400, which violates the ts-pattern requirement for conditional logic and the zinc palette styling requirement.

- Around line 568-572: The TransportStoreState interface is missing the
panelOpen field referenced elsewhere; update the interface (TransportStoreState)
in the spec so it includes panelOpen with the correct type (e.g., boolean) to
match what transport.store.ts persists (bpm, timeDisplayFormat, panelOpen), and
ensure any examples or tables in the document reflect this added property so the
spec is consistent with transport.store.ts.
In `@ui/src/lib/components/BottomToolbar.svelte`:
- Around line 188-239: The UI uses inline ternaries and {`#if`} blocks for OS and
state branching (isMac, isPlaying, isLeftSidebarOpen, $aiButtonState) — refactor
these into derived computations using ts-pattern's match(): create derived
stores (e.g., derivedIsMacLabel, derivedPlayIcon/state, derivedSidebarClass or a
single derived “by” object) that use match(isMac).with(...).run() /
match($aiButtonState).with(...).run() to compute the tooltip text, button
classes (aiButtonClass result), and loader vs sparkles rendering decision, then
replace the inline ternaries and {`#if` $aiButtonState.isLoading} blocks in
BottomToolbar.svelte to read from those derived values (referencing isMac,
isPlaying, isLeftSidebarOpen, $aiButtonState, aiButtonClass, onAiInsertOrEdit,
onBrowseObjects) so all branching logic lives in the derived match()
computations.
In `@ui/src/lib/components/FlowCanvasInner.svelte`:
- Around line 483-484: Move the eventBus.addEventListener registrations out of
onMount and into a Svelte $effect that registers each listener (e.g.,
eventBus.addEventListener('requestSaveSelectedAsPreset',
handleRequestSaveSelectedAsPreset) and
eventBus.addEventListener('quickAddConfirmed', handleQuickAddConfirmed')) and
returns a cleanup function that removes those same handlers; apply the same
$effect pattern to the other event listeners currently registered between the
handlers around lines 479–488 so registration happens reactively and removal
occurs when the effect is invalidated.
- Around line 621-630: Refactor handleRequestSaveSelectedAsPreset to use
ts-pattern's match(): import match from 'ts-pattern' and replace the nested ifs
with match(selectedNodeIds).when(length === 1, ids => match(nodes.find(n => n.id
=== ids[0])).with(P.where(n => !!n), node => { nodeToSaveAsPreset = node;
showSavePresetDialog = true }).otherwise(() => {})).otherwise(() => {}); i.e.,
perform a top-level match on selectedNodeIds to check length === 1, then a
nested match on the found node to ensure it exists before assigning
nodeToSaveAsPreset and toggling showSavePresetDialog.
In `@ui/src/lib/components/sidebar/PresetTreeView.svelte`:
- Around line 40-41: Refactor conditional logic to use ts-pattern's match() for
canSaveAsPreset instead of inline conditionals: derive canSaveAsPreset from
$selectedNodeInfo as now, then create match-derived values for the click handler
guard (used where the handler currently checks canSaveAsPreset at lines
~554-558) and for the button class string and tooltip text (used where
classes/tooltip are chosen at lines ~959-979). Replace the inline if/ternary
guards with match(canSaveAsPreset).with(true, ...).with(false, ...).exhaustive()
(or equivalent) so the button CSS class, tooltip message, and early-return guard
are produced from the same match-derived mapping; reference canSaveAsPreset, the
click handler function name, and the button class/tooltip variables when making
the changes.
In `@ui/src/lib/components/transport/TransportPanel.svelte`:
- Line 7: Remove the import of onMount and replace the onMount lifecycle block
with a Svelte 5 $effect block: move the polling/syncing logic currently inside
onMount (the interval creation, Transport state polling, volume sync, and any
initial calls) into a $effect(() => { ... }) callback and return a cleanup
function that clears the interval (e.g., return () =>
clearInterval(intervalId)); ensure references to any reactive props remain
accessible inside the $effect and that the new block uses the same identifiers
as the original (the previous onMount body, the intervalId variable, and any
Transport-related functions) so behavior is identical but Svelte 5 compatible.
- Around line 169-179: The play/pause button currently uses inline {`#if`} and
ternary logic; replace that with a ts-pattern match that derives the icon
component, title string, and click handler from the combined state of isPlaying
and isDspEnabled (similar to how timeDisplay is derived). Import match from
'ts-pattern', create a small derived object (e.g., const {Icon, title, onClick}
= match({isPlaying, isDspEnabled}).with(...).otherwise(...)) that returns
Pause/Play component refs, the title text ('Enable DSP first' when
!isDspEnabled, otherwise 'Pause' or 'Play'), and the appropriate handler
(handlePause or handlePlay), then update the button to use Icon, title, and
onClick and remove the inline {`#if`} and ternary title logic; reference symbols:
isPlaying, isDspEnabled, handlePause, handlePlay, Play, Pause, and timeDisplay
for consistency.
In `@ui/src/stores/transport.store.ts`:

pattern-match s.timeDisplayFormat (the TimeDisplayFormat union) and return the
next format explicitly (e.g., match('time').return('bars'),
match('bars').return('seconds'), match('seconds').return('time')); ensure the
returned state uses { ...s, timeDisplayFormat: <matched-next> } and keep the
function name toggleTimeDisplayFormat and the update call intact.
In `@ui/src/workers/rendering/fboRenderer.ts`:
- Around line 1351-1359: In defineWorkerGlobals update the globalThis 'time'
getter (and the other time-related getter around the block using transportTime)
to fall back to renderer.lastTime when renderer.transportTime is undefined so it
doesn't return 0 before the first sync; specifically change the getter logic to
return renderer.transportTime?.seconds ?? renderer.lastTime (or another existing
local time field) instead of 0, and apply the same fallback to the similar
getter in the following block (lines referencing transportTime and lastTime) so
both time getters use lastTime as the startup fallback.

(ChevronRight, ChevronDown, Library, LibraryBig, Folder, FolderOpen, FolderPlus,

- Around line 590-601: The "New Files" table in the design doc is missing the
TransportButton component entry; update the table by adding a row for
src/lib/components/transport/TransportButton.svelte and a short purpose like
"Play/Stop transport button (UI control)" so the new file is documented
alongside the other transport components; edit the table near the existing
transport component rows to include this filename and purpose.
- Line 653: Update the date string "Completed: 2024-02-24" to the correct year
"Completed: 2026-02-24" in the document (search for the exact text "Completed:
2024-02-24" and replace it with "Completed: 2026-02-24") so the completion
timestamp in the specs/77-global-transport-control.md file reflects the correct
year.
- Around line 657-667: The file table in specs/77-global-transport-control.md is
missing entries for constants.ts and TransportButton.svelte; update the markdown
table of "Files Created" to include rows for `src/lib/transport/constants.ts`
(describe purpose, e.g., shared transport constants) and
`src/lib/components/transport/TransportButton.svelte` (describe purpose, e.g.,
transport control button component) so the documentation lists all created files
consistently with the codebase.
In `@ui/src/lib/components/BottomToolbar.svelte`:
- Around line 31-34: The Play and Pause icons are imported from the deep path
'@lucide/svelte/icons'—change the import to use the package entrypoint by
importing Play and Pause from '@lucide/svelte' instead; update the import line
that currently references Play and Pause so it imports those symbols from
'@lucide/svelte' in BottomToolbar.svelte.
- Around line 178-182: The delete icon uses Tailwind's text-red-400 which
violates the Zinc-only styling rule; update the class on the Trash2 icon (within
BottomToolbar.svelte, inside Tooltip.Trigger/button using buttonClass and
handleDelete) to a Zinc palette color (for example text-zinc-400 or the
project’s designated zinc variant for dark theme) so the icon adheres to the
Zinc-only styling guideline.
- Line 103: The module-level use of navigator in the BottomToolbar.svelte file
(const isMac = /Mac|iPhone|iPad|iPod/.test(navigator.userAgent)) will crash
under SSR; change it to only access navigator at runtime by guarding with a
typeof check or by initializing isMac inside a client-only lifecycle hook (e.g.,
onMount) so navigator.userAgent is read only when window/navigator exist; update
the reference to isMac accordingly so it defaults safely (false or null) during
SSR and is populated on mount.
In `@ui/src/lib/components/ObjectPreviewLayout.svelte`:
- Line 2: The import line is using the non-standard entrypoint
'@lucide/svelte/icons'; update the import to use the project-standard
'@lucide/svelte' package entrypoint and keep the same named icons (Code, Pin,
PinOff, Play, X, Terminal) so the rest of ObjectPreviewLayout.svelte continues
to reference those symbols unchanged.
In `@ui/src/lib/components/transport/TransportPanel.svelte`:
- Around line 236-237: Replace red palette usage in icon class bindings with
zinc variants: wherever the icon class toggles on isMuted or volume === 0 (refer
to the class attribute using isMuted and volume) and where DSP off state is
shown (refer to dspEnabled/dsp toggle class around lines later), change
"text-red-400" (or any "text-red-*" value) to the appropriate zinc variant
(e.g., "text-zinc-400" or "text-zinc-500") so muted and DSP-off icons use the
Zinc palette consistent with dark-theme Tailwind guidelines.
In `@ui/src/workers/rendering/hydraRenderer.ts`:
- Around line 104-105: Guard assignment to Hydra synth time by validating
params.transportTime before setting this.hydra.synth.time: in hydraRenderer.ts
locate where this.hydra.synth.time = params.transportTime is used and change to
check that params && typeof params.transportTime === "number" &&
isFinite(params.transportTime) (or otherwise not null/undefined) and only then
assign; otherwise leave this.hydra.synth.time unchanged or set a safe default to
avoid assigning invalid values.

TransportStoreState pseudocode is missing the panelOpen field.
The "Files Created" table at line 664 documents that transport.store.ts persists bpm, timeDisplayFormat, **panelOpen** to localStorage, but the TransportStoreState interface definition here only declares bpm and timeDisplayFormat. The spec is internally inconsistent.

bpm: number;
timeDisplayFormat: "seconds" | "bars";

Convert event listener registration to $effect.
These event listeners are currently registered in onMount. Per Svelte 5 guidance, move event listener registration and cleanup to $effect:
- eventBus.addEventListener('requestSaveSelectedAsPreset', handleRequestSaveSelectedAsPreset);
- eventBus.addEventListener('quickAddConfirmed', handleQuickAddConfirmed);+ $effect(() => {
+ eventBus.addEventListener('requestSaveSelectedAsPreset', handleRequestSaveSelectedAsPreset);

+ return () => {

+ };
+ });Note: This pattern applies to all event listeners registered at lines 479–488, not just these two.

The component uses onMount for polling Transport state and syncing volume. Per Svelte 5 guidance, use $effect instead—the cleanup logic (returning a function to clear intervals) translates directly.
Remove the import { onMount } from 'svelte'; statement and convert the onMount hook to $effect:
♻️ Suggested change
-import { onMount } from 'svelte';- onMount(() => {
- // Poll transport state at 30fps for UI
- const interval = setInterval(() => {
- isPlaying = Transport.isPlaying;
- seconds = Transport.seconds;
- beat = Transport.beat;
- bpm = Transport.bpm;
- }, 1000 / 30);
-
- // Sync volume from AudioService
- const volumeInterval = setInterval(() => {
- if (!isMuted) {
- volume = audioService.outVolume;
- }
- }, 1000);
-
- return () => {
- clearInterval(interval);
- clearInterval(volumeInterval);
- };
- });
+ $effect(() => {
+ const interval = setInterval(() => {
+ isPlaying = Transport.isPlaying;
+ seconds = Transport.seconds;
+ beat = Transport.beat;
+ bpm = Transport.bpm;
+ }, 1000 / 30);

In `@ui/src/lib/components/transport/TransportPanel.svelte` at line 7, Remove the
import of onMount and replace the onMount lifecycle block with a Svelte 5
$effect block: move the polling/syncing logic currently inside onMount (the
interval creation, Transport state polling, volume sync, and any initial calls)
into a $effect(() => { ... }) callback and return a cleanup function that clears
the interval (e.g., return () => clearInterval(intervalId)); ensure references
to any reactive props remain accessible inside the $effect and that the new
block uses the same identifiers as the original (the previous onMount body, the
intervalId variable, and any Transport-related functions) so behavior is
identical but Svelte 5 compatible.

179, The play/pause button currently uses inline {`#if`} and ternary logic;
replace that with a ts-pattern match that derives the icon component, title
string, and click handler from the combined state of isPlaying and isDspEnabled
(similar to how timeDisplay is derived). Import match from 'ts-pattern', create
a small derived object (e.g., const {Icon, title, onClick} = match({isPlaying,
isDspEnabled}).with(...).otherwise(...)) that returns Pause/Play component refs,
the title text ('Enable DSP first' when !isDspEnabled, otherwise 'Pause' or
'Play'), and the appropriate handler (handlePause or handlePlay), then update
the button to use Icon, title, and onClick and remove the inline {`#if`} and
ternary title logic; reference symbols: isPlaying, isDspEnabled, handlePause,
handlePlay, Play, Pause, and timeDisplay for consistency.

Use ts-pattern to cycle through timeDisplayFormat.
The code branches based on the union type TimeDisplayFormat ('seconds' | 'bars' | 'time') to determine the next state. Per project guidelines, this state-based branching on union types must use ts-pattern instead of implicit iteration.

Fallback to local time before transport sync to avoid frozen time.
Right now the global time getter returns 0 until the first sync; using lastTime avoids a visible freeze on startup.

- Around line 459-465: In togglePlayPause, replace the if/else branch that
checks Transport.isPlaying with a ts-pattern match on Transport.isPlaying
(importing match from 'ts-pattern') and handle the play side as an async call to
avoid unhandled rejections by using void Transport.play() (or awaiting it if
togglePlayPause becomes async); keep the pause branch as Transport.pause() and
ensure togglePlayPause still exposes the same signature and behavior.
In `@ui/src/lib/components/transport/TransportPanel.svelte`:
- Around line 260-263: Muted volume icon currently uses text-red-400; update the
class expression in TransportPanel.svelte's svelte:component (this={volumeIcon})
so the conditional uses a Zinc tone (e.g., replace 'text-red-400' with
'text-zinc-400' or another appropriate Zinc shade) when isMuted || volume === 0;
ensure the rest of the class string remains unchanged so the dark-theme Zinc
palette is used consistently.
- Around line 58-64: Refactor the volumeIcon computed value to use ts-pattern's
match instead of the if chain: inside the const volumeIcon = $derived.by(() => {
... }) replace the sequence of ifs with a match that first checks isMuted (or
uses a guard) to return VolumeX when muted or volume === 0, then pattern-matches
volume ranges (.with(v => v < 0.33, () => Volume), .with(v => v < 0.66, () =>
Volume1)) and a .otherwise(() => Volume2); also add an import for match from
'ts-pattern' and ensure the $derived.by callback still references isMuted and
volume so reactivity is preserved.
In `@ui/src/lib/js-runner/JSRunner.ts`:
- Around line 273-305: The scheduler can be re-armed while a tick is mid-flight
because stopSchedulerTickLoop only deletes the frameId; add a per-node running
token (e.g., a Map<string, boolean> or a Set<string>) and use it in
startSchedulerTickLoop/stopSchedulerTickLoop and inside the tick closure: set
the token to true when starting (in startSchedulerTickLoop), set it to false
immediately in stopSchedulerTickLoop before cancelAnimationFrame and deleting
the frameId, and in the tick callback check the token for nodeId before calling
requestAnimationFrame so a stopped node will not reschedule itself; update uses
of schedulerTickLoops, startSchedulerTickLoop, stopSchedulerTickLoop, and the
tick closure to reference this token for safe cleanup.
- Around line 261-266: Refactor getScheduler to replace the manual if-check on
schedulerMap with a ts-pattern match: pattern-match
this.schedulerMap.get(nodeId) (or this.schedulerMap.has(nodeId)) to handle the
present/absent cases and return the existing PollingClockScheduler or set and
return a new PollingClockScheduler via this.schedulerMap.set(nodeId, new
PollingClockScheduler()); do the same refactor for getMessageContext so both
methods use ts-pattern matching instead of an if guard; reference the
schedulerMap, getScheduler, getMessageContext, and PollingClockScheduler
identifiers when making the change.
In `@ui/src/lib/services/KeyboardShortcutManager.ts`:
- Around line 213-219: The spacebar handler in KeyboardShortcutManager currently
only checks isTypingContext and always calls event.preventDefault(), which
blocks activation of focused interactive elements; update the logic (e.g., in
the keydown handler / handleKeydown) to detect interactive focused elements by
checking document.activeElement for tagName in
['BUTTON','A','INPUT','SELECT','TEXTAREA'], presence of href on anchors,
contentEditable, or roles like role="button" and skip preventDefault when focus
is on such controls; then refactor the conditional to use ts-pattern to match on
the pressed key (' ') and the computed "isInteractiveFocus || isTypingContext"
boolean so you only call event.preventDefault() and
this.actions.togglePlayPause() when the spacebar is pressed and focus is not on
an interactive control (use this.actions.togglePlayPause() as before).
In `@ui/src/lib/transport/ClockScheduler.ts`:
- Around line 170-177: The code branches on union types using raw
typeof/Array.isArray checks (in PollingClockScheduler methods including onBeat
and the code paths around beats/time handling) which violates the guideline to
use ts-pattern; replace those conditional branches with ts-pattern's match
calls: for onBeat (convert the typeof beat === 'number' ? [beat] : beat logic)
use match(beat).with(Number, b => [b]).with(Array, b => b).with('*', () =>
['*']).run(); likewise replace the beats === '*' / Array.isArray(beats) checks
and the typeof time === 'string' ? parseBarBeatSixteenth(...) : time branch by
using match(time).with(String, s => parseBarBeatSixteenth(...)).with(Number, n
=> n).run(); update imports to include match from 'ts-pattern' and adjust
PollingClockScheduler methods accordingly.
- Around line 188-200: The issue: every() seeds lastFired as 0 causing immediate
callback if transport already past first interval; fix by adding an optional
parameter (e.g., currentTimeSeconds?: number) to every(interval: string,
callback: () => void, currentTimeSeconds?: number) and use that value to
initialize lastFired (use currentTimeSeconds ?? 0) when inserting into
repeatCallbacks; update callers such as createWorkerClock to pass
renderer.transportTime?.seconds ?? 0 so newly-registered entries are seeded to
current transport time and won't fire immediately.
- Around line 59-69: ClockWithScheduler type omits the public ticks property
used by createClockWithScheduler and manually added in
FBORenderer.createWorkerClock; update the ClockWithScheduler type to include a
readonly ticks: number (or a getter signature matching the spec) so objects
returned by createClockWithScheduler expose ticks consistently, and then remove
the ad-hoc addition in FBORenderer.createWorkerClock or keep it but ensure it
matches the typed signature; refer to ClockWithScheduler,
createClockWithScheduler, FBORenderer.createWorkerClock, and the ticks getter
when making the change.
- Around line 83-92: parseBarBeatSixteenth currently maps notation parts with
Number and lets NaN propagate; validate the parsed parts and bpm and fail fast
with a clear error instead of silently returning NaN: after computing parts (the
array assigned to variable parts and the derived bars, beats, sixteenths), check
Number.isFinite on each numeric part and on bpm/beatsPerSecond, and if any are
invalid throw a descriptive Error (including the bad notation and which
component failed) so callers can surface diagnostics instead of scheduling
silently breaking; keep the same return behavior for valid inputs.
In `@ui/src/workers/rendering/fboRenderer.ts`:
- Around line 862-868: The clockState used before transport sync defaults time
and beat to 0 which triggers spurious beat-0 callbacks; update the clockState
construction (the object passed into clockScheduler.tick in fboRenderer.ts) to
use this.transportTime?.seconds ?? this.lastTime for time and
this.transportTime?.beat ?? this.lastBeat (or explicitly use -1 for beat to
match lastBeat's initial value) so the pre-sync tick matches the renderer's
fallback logic and avoids firing beat callbacks prematurely.

Outside diff comments:
In `@docs/design-docs/specs/77-global-transport-control.md`:
- Around line 297-303: The JSRunner clock example defines a stale property key
"progress" that was renamed to "phase"; update the clock object so the property
key matches the Transport field (replace progress with phase) in the
JSRunner/clock pseudocode (symbols: clock, Transport.phase) and keep the same
value/comment "(ticks % PPQ) / PPQ".
---
Duplicate comments:
In `@docs/design-docs/specs/77-global-transport-control.md`:
- Around line 568-572: The TransportStoreState interface is missing the
panelOpen property referenced elsewhere; update the TransportStoreState
interface (in this spec) to include panelOpen: boolean so it matches the
persisted state in transport.store.ts and the "Files Created" table, ensuring
consumers of TransportStoreState and any serialization/rehydration logic
expecting panelOpen remain consistent.
- Around line 590-601: The spec's summary tables are inconsistent:
TransportButton.svelte is missing from both the "Files to Create" and "Files
Created" tables and src/lib/transport/constants.ts appears in the "Files to
Create" table but not in the "Files Created" table; update the markdown tables
so TransportButton.svelte is listed in both the planned and created file tables
and add src/lib/transport/constants.ts to the "Files Created" table (ensure the
table rows match the names used elsewhere like TransportButton.svelte and
constants.ts for consistency).
- Line 653: Update the erroneous completion date string "Completed: 2024-02-24"
to the correct year by changing it to "Completed: 2026-02-24" wherever that
exact line appears (the completion metadata line in
specs/77-global-transport-control.md). Ensure the date format remains YYYY-MM-DD
and run a quick search for any other occurrences of "Completed: 2024-" to
correct them as well.
In `@ui/src/lib/components/FlowCanvasInner.svelte`:
- Around line 629-638: Refactor handleRequestSaveSelectedAsPreset to use
ts-pattern instead of nested ifs: import and use match from "ts-pattern" and
match on selectedNodeIds to check for a single-element array, then within that
branch use match or a guard to find the node by id from nodes; if found, set
nodeToSaveAsPreset and showSavePresetDialog. Replace the current
selectedNodeIds.length === 1 and nodes.find(...) nested checks with a single
ts-pattern match flow that handles the single-id case and the node existence
case using patterns/when guards.
- Around line 487-492: The listener registrations for eventBus
(eventBus.addEventListener calls that register handleNodeReplace,
handleVfsPathRenamed, handleInsertVfsFile, handleInsertPreset,
handleRequestSaveSelectedAsPreset, handleQuickAddConfirmed) are currently done
in onMount; move them into a Svelte $effect block so they run/react with
component lifecycle, and register corresponding cleanup by removing those
listeners (eventBus.removeEventListener) when the effect is disposed; ensure you
remove the same handler function references (handleNodeReplace,
handleVfsPathRenamed, handleInsertVfsFile, handleInsertPreset,
handleRequestSaveSelectedAsPreset, handleQuickAddConfirmed) and delete the
onMount import/usages if no longer needed.
In `@ui/src/lib/components/transport/TransportPanel.svelte`:
- Around line 286-289: The DSP toggle in TransportPanel.svelte uses red Tailwind
classes — replace the conditional branch that applies 'bg-red-900/50
text-red-400 hover:bg-red-900/70' when isDspEnabled is false with Zinc palette
equivalents (e.g., darker zinc background and zinc-400/300 text/hover variants)
so the component adheres to the "Use Zinc palette with dark theme" rule; locate
the class string in the TransportPanel.svelte component where the isDspEnabled
conditional is used and swap the red classes for appropriate zinc classes while
preserving the same semantic contrast and hover behavior.
- Around line 169-189: Replace the inline Svelte {`#if`} branching for play/pause
UI with values derived via ts-pattern: in the component script use ts-pattern's
match on the boolean isPlaying (and isDspEnabled where label differs) to compute
three derived symbols—playIcon (either the Play or Pause component reference),
playLabel (string for tooltip content), and playAction (either handlePlay or
handlePause function) — then update the button and tooltip to use
onclick={playAction}, render {playIcon} inside the button, and use {playLabel}
(or a conditional derived via ts-pattern that includes the "Enable DSP first"
message when !isDspEnabled) in Tooltip.Content; ensure you import match from
'ts-pattern' and remove the {`#if`} blocks referencing isPlaying/isDspEnabled in
the markup.
- Around line 143-163: The component uses onMount to start polling intervals;
replace that with a Svelte 5 $effect block so the timers run reactively and
cleanup correctly. Inside $effect(() => { ... }) create the two intervals that
update isPlaying, seconds, beat, bpm from Transport and volume from audioService
(respecting isMuted), store them in local consts (e.g., transportInterval,
volumeInterval), and return a cleanup function that calls clearInterval on both;
remove the onMount import/usages and ensure you reference Transport,
audioService, isPlaying, seconds, beat, bpm, isMuted, and volume exactly as in
the diff so the new $effect mirrors the previous logic.
In `@ui/src/lib/transport/StubTransport.ts`:
- Around line 15-43: Replace the plain if in the seconds getter with a
ts-pattern match on this._isPlaying (use match(this._isPlaying).with(true, () =>
...) / .with(false, () => ...)) so conditional logic follows the guideline; and
make play() idempotent by returning early when this._isPlaying is already true
(do not reset startTime or pausedAt on repeated calls). Update the seconds
getter to compute running time only when matched true and return pausedAt when
matched false, and ensure play() only sets startTime and this._isPlaying when
transitioning from stopped to playing.
In `@ui/src/lib/transport/ToneTransport.ts`:
- Around line 62-70: The if/else in setDspEnabled should be replaced with a
ts-pattern match on the boolean `enabled`; import `match` from 'ts-pattern' and
use `await match(enabled).with(true, async () => { await ctx.resume();
}).with(false, async () => { await (ctx as AudioContext).suspend();
}).exhaustive()` (referencing the `setDspEnabled` method and the
`ctx`/`this.tone.getContext().rawContext` variables) so the branch conforms to
the ts-pattern guideline and still awaits resume/suspend appropriately.
In `@ui/src/lib/transport/Transport.ts`:
- Around line 41-44: The play() method can race and call upgrade() concurrently;
replace the simple if-check with a guarded upgrade lock and ts-pattern matching:
add a private field (e.g., upgradePromise: Promise<void> | null) to Transport,
use ts-pattern to match the tri-state ({ upgraded, upgradeDisabled,
upgradePromise }) and if not upgraded and not disabled and no in-flight upgrade,
set upgradePromise = upgrade() and await it (other concurrent play() callers
should await the same upgradePromise), finally clear upgradePromise after
completion; reference play(), upgrade(), upgraded, upgradeDisabled, and the new
upgradePromise field when implementing.
In `@ui/src/workers/rendering/fboRenderer.ts`:
- Around line 1363-1372: The getter for globalThis.time in defineWorkerGlobals
uses "renderer.transportTime?.seconds ?? 0", causing time to freeze at 0 before
first sync; change the fallback to a locally-elapsed time instead of 0. Update
the getter on globalThis.time (inside defineWorkerGlobals) to return
renderer.transportTime?.seconds ?? ((performance.now()/1000) -
renderer.startTimestamp) or similar local-clock value (create
renderer.startTimestamp when the worker starts if it doesn't exist) so time
advances locally until transportTime is available.
- Around line 1383-1411: createWorkerClock's getters (time, ticks, beat, phase,
bpm) currently default straight to 0/120 using "??" on renderer.transportTime,
which causes them to report 0 before sync; update each getter to prefer a
locally-available fallback before the hard default, e.g. replace
renderer.transportTime?.seconds ?? 0 with renderer.transportTime?.seconds ??
renderer.localTransportTime?.seconds ?? 0 (and similarly for ticks/beat/phase,
and bpm using ?? renderer.localTransportTime?.bpm ?? 120) so the clock uses the
local cached values when transportTime is not yet synced; keep the scheduler
bindings (clockScheduler.onBeat/schedule/every/cancel/cancelAll) unchanged.

Nitpick comments:
In `@ui/src/workers/rendering/fboRenderer.ts`:
- Around line 84-91: The inline 6-field transport state type used by the
transportTime property and the setTransportTime parameter should be replaced
with a single shared named type (e.g., TransportState) to avoid duplication;
update the declaration of the transportTime field and the signature of
setTransportTime to reference the existing TransportState type exported by the
transport layer (or create and export TransportState if missing), ensuring the
shape (seconds, ticks, bpm, isPlaying, beat, phase) is represented by that type
so both transportTime and setTransportTime remain in sync.

Use ts-pattern for the play/pause branch (and avoid unhandled async play).

The if guard at line 262 violates the rule requiring ts-pattern for all conditional logic in TypeScript files. Refactor to match-based pattern.

Stop the scheduler RAF loop without re-arming after destroy.
stopSchedulerTickLoop() can run while a tick is executing. The tick then schedules another frame after the map entry is deleted, so the loop can continue and leak. Add a per-node running token/flag so a tick won’t reschedule once stopped.

ClockWithScheduler is missing ticks, creating an inconsistency with createWorkerClock.
createClockWithScheduler produces an object typed as ClockWithScheduler which omits ticks, yet FBORenderer.createWorkerClock() manually adds a ticks getter. Any code using the shared factory will silently lack ticks. If ticks is part of the public clock surface (the spec at line 299 includes it), it should be in both the type and the factory.

ClockWithScheduler type omits the public ticks property used by
createClockWithScheduler and manually added in FBORenderer.createWorkerClock;
update the ClockWithScheduler type to include a readonly ticks: number (or a
getter signature matching the spec) so objects returned by
createClockWithScheduler expose ticks consistently, and then remove the ad-hoc
addition in FBORenderer.createWorkerClock or keep it but ensure it matches the
typed signature; refer to ClockWithScheduler, createClockWithScheduler,

parseBarBeatSixteenth silently returns NaN for invalid notation.
If notation doesn't contain colons (e.g., a user typo like "1bar") Number("1bar") produces NaN, which propagates through all arithmetic and causes scheduled callbacks to never fire with no diagnostic message.

parseBarBeatSixteenth currently maps notation parts with Number and lets NaN
propagate; validate the parsed parts and bpm and fail fast with a clear error
instead of silently returning NaN: after computing parts (the array assigned to
variable parts and the derived bars, beats, sixteenths), check Number.isFinite
on each numeric part and on bpm/beatsPerSecond, and if any are invalid throw a
descriptive Error (including the bad notation and which component failed) so
callers can surface diagnostics instead of scheduling silently breaking; keep
the same return behavior for valid inputs.

every() fires immediately when the transport is already past the first interval.
lastFired is initialized to 0, so on the very first tick() after registration the check clock.time >= 0 + interval fires the callback immediately if the transport is already running. A user adding a node mid-session would see an unexpected immediate invocation.
🐛 Proposed fix — initialize `lastFired` to current transport time
Pass the current time as an optional parameter so lastFired is seeded correctly:
- every(interval: string, callback: () => void): string {
+ every(interval: string, callback: () => void, startTime = 0): string {
const id = generateId();
const intervalSecs = parseBarBeatSixteenth(interval, this.currentBpm);

- lastFired: 0,

});Callers that know the current transport time (e.g., createWorkerClock) can pass renderer.transportTime?.seconds ?? 0.

clockState defaults time and beat to 0, causing spurious beat-0 callbacks on startup.
Before the first syncTransportTime message arrives, the scheduler is ticked with time=0 and beat=0. Because lastBeat is initialized to -1, the beat-change guard (clock.beat !== this.lastBeat) is immediately satisfied, firing all beat-0 callbacks on the very first frame—before playback has actually started.
The render path already correctly uses ?? this.lastTime as a fallback (line 961); the clockState should match.
🐛 Proposed fix
const clockState: ClockState = {
- time: this.transportTime?.seconds ?? 0,
- beat: this.transportTime?.beat ?? 0,
+ time: this.transportTime?.seconds ?? this.lastTime,
+ beat: this.transportTime?.beat ?? -1,
bpm: this.transportTime?.bpm ?? 120
};Using beat: -1 as the fallback (matching lastBeat's initial value) prevents the spurious beat-0 callback during the pre-sync period.
