Inline comments:
In `@apps/frontend/package.json`:
- Line 83: The package "@types/html2canvas" is listed under dependencies but it
should be a development-only type package; edit package.json to remove
"@types/html2canvas" from the "dependencies" object and add the same entry (with
the same version "^0.5.35") to the "devDependencies" object so type definitions
are installed for development but not bundled into production.
In `@apps/frontend/src/renderer/components/timeline/BuildTimeline.tsx`:
- Around line 251-257: The layouts (calculateAllPhaseLayouts,
calculateAllSubtaskLayouts, calculateTimelineWidth, calculateTimelineHeight)
already include viewState.zoom, so remove the extra scaling applied in the
wrapper transform (the element that uses viewState.zoom to set a CSS/SVG scale)
so zoom is applied only once; update the wrapper transform to apply
pan/translate only (keep viewState.pan/offsets) and ensure all references to the
wrapper transform code paths (where phaseLayouts, subtask layouts, and timeline
width/height are used) no longer multiply by viewState.zoom to avoid
double-scaling.
- Around line 124-130: handleScrollChange currently only updates React state
(viewState) so UI controls that depend on the DOM scroll (pan buttons,
drag-to-pan, handleWheel) don't move the viewport; update
timelineRef.current.scrollLeft and timelineRef.current.scrollTop whenever
viewState.scrollX/scrollY are set. Specifically, in handleScrollChange and in
the other scroll setters referenced (the handlers at the other diffs and any
places that set viewState.scrollX/scrollY, e.g., the pan button handlers and
wheel/drag handlers), after computing the new scrollX/scrollY call something
like: if (timelineRef.current) { timelineRef.current.scrollLeft = scrollX;
timelineRef.current.scrollTop = scrollY; } while still calling setViewState, and
ensure this guard prevents null refs so you don’t attempt to write to the DOM
when timelineRef is not mounted; also update handleWheel’s focus-preserving
branch to sync the DOM scroll when it adjusts viewState.
- Around line 307-309: Remove the hardcoded English fallbacks from the JSX where
the i18n translator t(...) is used (e.g., the t('timeline.loading') expressions
in BuildTimeline.tsx and the similar occurrences around the other noted spots),
so instead of using `t('namespace:key') || 'Hardcoded English'` rely solely on
`t('timeline.loading')` (or the correct timeline keys) and add the corresponding
keys to the translation resources for English and French (update both language
files with namespace: timeline.loading, timeline.[otherKey] matching the UI
texts shown at the four locations). Ensure the components call only t(...) with
the correct namespace:section.key strings and that the translation JSONs contain
those keys for en and fr so missing-key fallbacks to English are eliminated.
In `@apps/frontend/src/renderer/components/timeline/DependencyConnector.tsx`:
- Around line 76-111: getDependencyColor and getDependencyAgentType duplicate
the same phase/subtask lookup logic; create a single helper (e.g.,
getDependencyTargetInfo or resolveDependencyTarget) that accepts a
TimelineDependency and returns the resolved agentType (and optionally the
phase/subtask id) so both getDependencyColor and getDependencyAgentType can call
it; update getDependencyColor to use the returned agentType to pick
DEPENDENCY_COLORS and update getDependencyAgentType to return the same agentType
(falling back to 'inactive') and remove the duplicated find(...) logic from both
functions.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineData.ts`:
- Around line 143-152: The returned object in useTimelineData currently sets
createdAt and updatedAt to new Date(), which is wrong; change useTimelineData to
use the plan's real timestamps (map ImplementationPlan.created_at -> createdAt
and created_at/updated_at -> updatedAt using new Date(plan.created_at) / new
Date(plan.updated_at) or handle null/undefined appropriately) so the returned
shape reflects actual plan times; also update the call site that consumes
useTimelineData (the invocation referenced in the PR) to ensure it passes the
ImplementationPlan (or its created_at/updated_at values) and handle any typing
adjustments for createdAt/updatedAt in consumers.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineExport.ts`:
- Around line 172-188: The second export call should be removed: capture and
reuse the result from exportAndDownloadImage instead of calling exportAsImage
again. Modify exportAndDownloadImage to return the exported image/canvas result
(or update its signature if needed), then replace the await exportAsImage(...)
call with the returned value (e.g., const canvas = await
exportAndDownloadImage(...)); keep the abort check using
exportRef.current.aborted and only call onExportSuccess with
canvas.filename/width/height when not aborted.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineLayout.ts`:
- Around line 203-217: The drag-distance accumulation is incorrect: instead of
adding the full distance-from-start on every mousemove, compute the current
movement from dragStartRef (deltaX/deltaY) and set dragDistanceRef.current to
that (or to Math.max(previous, current)) so small jitter doesn't rapidly exceed
DRAG_THRESHOLD; update the logic in the mousemove handlers (the code around
handleMouseDown / dragStartRef / dragDistanceRef / DRAG_THRESHOLD and the
similar blocks at the other mentioned locations) to use currentDistance =
Math.hypot(deltaX, deltaY) and assign or max-assign that value rather than
adding it.
In `@apps/frontend/src/renderer/components/timeline/PhaseSwimLane.tsx`:
- Around line 113-122: The JSX always sets role="button" causing non-interactive
elements to be announced as buttons; update the PhaseSwimLane component so the
role attribute is only present when the onClick prop exists (same condition used
for tabIndex and onKeyDown). Locate the element using the onClick={handleClick}
and handleClick/onClick props and change role="button" to a conditional
expression (e.g., role={onClick ? "button" : undefined}) so role, tabIndex and
the keyboard handler are consistently applied only for interactive instances.
- Line 75: The component PhaseSwimLane declares const { t } =
useTranslation('tasks') but never uses it; either remove the unused import and
the useTranslation call (delete the useTranslation import and the const { t }
line) or preferably use t for the hardcoded aria-label on the swimlane element:
add a translation key (e.g., "phaseSwimLane.ariaLabel") to the appropriate i18n
namespace and replace the hardcoded aria-label string with
t('phaseSwimLane.ariaLabel'), ensuring the namespace passed to useTranslation
matches where you added the key.
In `@apps/frontend/src/renderer/components/timeline/SubtaskBlock.tsx`:
- Around line 210-215: The expanded detail panel inside SubtaskBlock is being
clipped because it stays inside the parent container that uses a fixed layout
height with overflow-hidden; update the expansion so the motion.div
(detailPanel) is removed from the parent's overflow context when expanded—e.g.,
render the detailPanel in a sibling container or portal (outside the element
applying layout.height/overflow-hidden) and adjust the animation to animate
height/opacity on that element; locate the detailPanel/motion.div usage in
SubtaskBlock and any other similar motion.div blocks at the noted ranges (around
lines where detailPanel is declared and the other two occurrences) and move
their rendering out of the fixed-height container or change the parent layout to
allow auto height while retaining the card's layout behavior.
- Around line 219-220: Replace all hardcoded user-facing strings in the
SubtaskBlock component (e.g., the "Description:" label, expanded panel labels,
aria-label values, and raw status values like "pending"/"failed") with
react-i18next translation keys using the namespace:section.key format via the
useTranslation hook (e.g., t('subtask.description')). For status values, map
internal status codes to translated labels (e.g., statusMap[status] =
t('subtask.status.pending')) before rendering and use these translated strings
in aria-labels and UI. Ensure every new key is added to the English and French
language files (minimum) with appropriate translations. Update all occurrences
noted (around the areas rendering description, expanded panel labels, status
displays, and aria-labels) so no JSX contains hardcoded text.
In `@apps/frontend/src/renderer/components/timeline/TimelineControls.tsx`:
- Around line 148-149: The JSX currently uses hardcoded English fallbacks for
user-facing strings in TimelineControls (e.g., title and aria-label on the zoom
buttons and the export button text); replace those inline literals with i18n
keys via the react-i18next translator (use the existing t function, e.g.,
t('timeline:controls.zoomIn') instead of fallback strings) for every control
referenced (TimelineControls component: zoom in/out, pan, export, etc. — see
uses of title/aria-label and export button text around the component and the
other affected lines 162-163, 179-180, 207-216, 240-241, 257-258, 276-277,
293-294), and add the corresponding keys to the English and French locale files
so the translations exist (namespace format namespace:section.key as per
guidelines).
In `@apps/frontend/src/renderer/components/timeline/utils/export-as-image.ts`:
- Around line 37-43: The code currently allows config.format === 'svg' but
always serializes PNG bytes (calls toBlob/toDataURL with 'image/png') so callers
get a .svg file with PNG content; update DEFAULT_EXPORT_OPTIONS and the exporter
in export-as-image.ts to either (A) remove/forbid 'svg' from
TimelineExportOptions or (B) implement a real SVG export path — if you choose
(A) validate config.format in the export function and if format === 'svg' either
throw a clear error or fallback to 'png' (and log/warn), and ensure the
serializer passes the correct MIME to toBlob/toDataURL (use 'image/png' or
'image/jpeg' as appropriate) and derive the filename extension from the actual
MIME/serialization result rather than from config.format; apply this fix at
every serialization site that calls toBlob/toDataURL so DEFAULT_EXPORT_OPTIONS,
the export routine(s) handling config.format, and any filename construction use
the real output format/mime consistently.
In `@apps/frontend/src/renderer/components/timeline/utils/timeline-layout.ts`:
- Around line 39-57: calculatePhaseLayout currently returns width/totalWidth as
0 and computes height ignoring config.phaseHeight; update calculatePhaseLayout
to (1) compute contentHeight = ((subtaskHeight + verticalPadding*2) * zoom) +
(Math.max(0, (subtasks.length - 1)) * subtaskSpacing * zoom) and then set height
= Math.max(config.phaseHeight * zoom, contentHeight), and (2) compute width as
the maximum content width of the phase (e.g., max of each subtask.width * zoom
or derived subtaskContentWidth) and totalWidth as the sum of all subtask widths
plus horizontal spacing (all scaled by zoom); use the existing symbols
calculatePhaseLayout, phaseHeight, subtaskHeight, subtaskSpacing, zoom,
phaseIndex, subtasks, verticalPadding, width, totalWidth, and height so
downstream calculatePhaseDependencyPath() / isPointInPhase() get correct
dimensions.
In `@apps/frontend/src/shared/i18n/locales/en/timeline.json`:
- Around line 1-61: Create a French locale file that mirrors every key in the
English "timeline" JSON (e.g., keys like "title", "description", "loading",
"controls.zoomIn", "phases.planning", "status.in_progress",
"export.buttonLabel", etc.) with accurate French translations; ensure the JSON
structure and keys exactly match the English file so react-i18next can resolve
namespace:timeline keys and update any UI usage of those keys (no new or missing
keys), and add translated values for all nested sections such as "controls",
"phases", "status", "time", "subtask", and "export".
- Around line 1-61: Register the missing "timeline" namespace and add French
translations: in the i18n module import enTimeline and frTimeline (e.g., import
enTimeline from './locales/en/timeline.json' and import frTimeline from
'./locales/fr/timeline.json'), add timeline: enTimeline to resources.en and
timeline: frTimeline to resources.fr, and include 'timeline' in the ns array so
useTranslation('timeline') resolves; also create the fr timeline JSON containing
French translations for every key present in the provided en timeline.json
(matching the same key structure).

Localize the detail labels and accessible name.
The expanded panel and aria-label still hardcode English text, including raw status values like pending and failed, so this component will not follow the active locale.
As per coding guidelines, "All user-facing text must use i18n translation keys from react-i18next with format namespace:section.key. Never use hardcoded strings in JSX/TSX. Update all language files (minimum: English and French) when adding new text."

Drop the hardcoded control fallbacks.
Tooltips, aria-labels, and the export button text still embed English strings, so localized builds will quietly fall back to English instead of failing through the locale files.

Don't expose svg until the exporter can actually produce SVG bytes.
This path always serializes PNG data (toBlob(..., 'image/png') / toDataURL('image/png')) and then derives the filename extension from config.format. Passing svg therefore gives callers a .svg file that still contains PNG content.
Also applies to: 67-70, 175-183

Missing French translation file.
Per coding guidelines, all user-facing text must have translations for minimum English and French. A corresponding apps/frontend/src/shared/i18n/locales/fr/timeline.json file is required.

Create a French locale file that mirrors every key in the English "timeline"

"phases.planning", "status.in_progress", "export.buttonLabel", etc.) with

any UI usage of those keys (no new or missing keys), and add translated values
for all nested sections such as "controls", "phases", "status", "time",
"subtask", and "export".

Missing i18n namespace registration and French translation — timeline features will fail at runtime.
The timeline namespace is not registered in apps/frontend/src/shared/i18n/index.ts. Any component using useTranslation('timeline') will fail to resolve these keys. Additionally, the French translation file is missing.
Required changes in apps/frontend/src/shared/i18n/index.ts:
- Import:
import enTimeline from './locales/en/timeline.json';andimport frTimeline from './locales/fr/timeline.json'; - Add
timeline: enTimelinetoresources.enandtimeline: frTimelinetoresources.fr - Add
'timeline'to thensarray
Create apps/frontend/src/shared/i18n/locales/fr/timeline.json with French translations for all keys.

To fix the problem, remove the unused variable declaration so that all locally declared variables are actually used. This avoids unnecessary computation and clears the static analysis warning without altering behavior.
Concretely, in apps/frontend/src/renderer/components/timeline/utils/timeline-layout.ts, within calculateBezierPath, remove the dy computation on line 331. The rest of the function remains unchanged. No new imports or definitions are required, and no external behavior will change because dy was never read.

Inline comments:
In `@apps/frontend/src/renderer/components/timeline/BuildTimeline.tsx`:
- Around line 362-371: The interactive timeline container is not
keyboard-accessible; make it focusable and handle arrow-key panning by adding
tabIndex={0} to the div (where containerRef is used) and wiring an onKeyDown
handler (e.g., handleKeyDown) that maps ArrowLeft/ArrowRight (and optionally
ArrowUp/ArrowDown / PageUp/PageDown) to the same pan logic used by
handleMouseMove/handleMouseDown or to the existing pan/scroll state updater
(reuse whatever function updates offset/translate in this component); also add
an accessible label/role or aria-label to the container so keyboard users can
discover it. Ensure handleKeyDown calls the same internal pan function (or
dispatch) so behavior matches mouse drag and that focus styling is preserved.
- Around line 228-229: Remove the stray debug console.log in the
handlePhaseClick callback inside BuildTimeline.tsx: delete the line
`console.log('[BuildTimeline] Phase clicked:', \`phase-${phase.phase}\`,
phase.name);` and, if needed, replace it with the application's
logging/telemetry utility (or nothing) so production code contains no console
debugging; ensure the change is made in the handlePhaseClick useCallback
implementation and that behavior and dependencies remain unchanged.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineData.ts`:
- Around line 77-87: The current code assigns executionProgress.phase to every
TimelinePhase via progress.status; change this so only the active swimlane (when
isCurrentPhase is true) gets executionProgress.phase. In the block that builds
the PhaseProgressData (progress), set status = isCurrentPhase ?
executionProgress?.phase : (completedSubtasks === totalSubtasks ? 'completed' :
'pending') and keep currentSubtaskId = isCurrentPhase ?
executionProgress?.currentSubtask : undefined; leave progress percentage,
completedCount and totalCount as-is. Update references to isCurrentPhase,
executionProgress, phase.type, currentSubtaskId, completedSubtasks and
totalSubtasks accordingly.
- Around line 166-180: The loadData function in useTimelineData must ignore
stale async responses: add a request token (e.g., a ref or incrementing
requestId stored in the hook) before calling
window.electronAPI.getImplementationPlan(taskId), capture that token in the
async response handler and verify it still matches the latest token before
calling setImplementationPlan, setError or setIsLoading; alternatively use an
AbortController tied to the current request and abort previous calls when taskId
changes. Ensure you reference and update the token when loadData runs and check
it right after awaiting getImplementationPlan (for the success and error paths)
so only the most recent taskId's response mutates state.
- Around line 173-178: The hook useTimelineData should return i18n error keys
instead of hardcoded English messages: replace thrown Error and setError calls
that currently use planResult.error || 'Failed to load implementation plan' and
'Failed to load timeline data' with standardized error keys (e.g.,
'timeline:errors.loadPlan' or 'timeline:errors.loadData') or propagate
planResult.error as a key when appropriate; update the setError usage in
useTimelineData to set the key string, and update BuildTimeline.tsx to call
t(error) when rendering; also add the new translation entries to the timeline
namespace for English and French to match the keys.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineExport.ts`:
- Around line 267-272: The clipboard export success currently calls
onExportSuccess with width: 0 and height: 0; update the clipboard export flow in
useTimelineExport (the function handling clipboard exports / the
exportToClipboard branch) to compute the actual exported image dimensions (e.g.,
from the generated canvas or image element used for the clipboard copy) and pass
those real width and height values along with the filename (still using
t('export.clipboardFilename', ...)) into onExportSuccess so consumers receive
correct dimensions.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineLayout.ts`:
- Around line 164-198: The wheel handler (handleWheel) and the related
drag/mouse handlers update viewState using the object form
setViewState({...viewState,...}) which can cause lost updates under rapid
events; change these to the functional updater form setViewState(prev =>
({...prev, zoom: newZoom, scrollX: ..., scrollY: ...})) so each update composes
from the latest state. Apply the same change to the drag/mousemove handler(s)
that modify viewState (e.g., your drag handler/handleMouseMove) and to
handleMouseUp so they all use setViewState(prev => ...) and compute
newZoom/newScroll from prev.zoom/prev.scrollX/prev.scrollY (use
calculateScrollAfterZoom with those prev values).
In `@apps/frontend/src/renderer/components/timeline/PhaseSwimLane.tsx`:
- Around line 216-218: Replace the hardcoded fallback string 'unknown' in the
PhaseSwimLane component (where it renders {phase.agentType || 'unknown'}) with a
translated string: add a "phases.unknown" key to the timeline.json locale files
(both en and fr) and use the i18n translator (e.g., the t function from
useTranslation) in PhaseSwimLane to render t('timeline.phases.unknown') when
phase.agentType is falsy; ensure the component imports/uses the existing
translation hook (useTranslation or equivalent) and reference phase.agentType ||
t('timeline.phases.unknown') so the UI is localized.
In `@apps/frontend/src/renderer/components/timeline/SubtaskBlock.tsx`:
- Around line 228-231: Replace the array index key with the file path string for
the mapped list items in SubtaskBlock: use the unique file identifier (the
`file` variable) as the React key in the `subtask.filesToCreate.map(...)` render
and make the identical change for `subtask.filesToModify.map(...)` to ensure
stable reconciliation when list order changes.
- Around line 154-158: The nested ternary that computes timeColorClass in
SubtaskBlock.tsx increases cognitive load; extract it into a small helper or
lookup (e.g., getTimeColorClass or TIME_COLOR_MAP) that takes timeVariance and
returns the class string, then replace the inline ternary with a call to that
helper; ensure you export or place the helper near the component so tests and
other components can reuse it if needed and keep the existing class values
('text-destructive', 'text-green-600 dark:text-green-400',
'text-muted-foreground') unchanged.
In `@apps/frontend/src/renderer/components/timeline/TimelineControls.tsx`:
- Around line 129-136: The export filter is missing class names on the control
containers, so add the export-ignore classes to the relevant JSX: in
TimelineControls (the motion.div that renders Zoom controls when
showZoomControls is true) include the "zoom-controls" class; add
"export-controls" to the container that renders the export button/component (the
export button wrapper) and add "pan-controls" to the Pan controls container (the
motion.div or wrapper that renders pan buttons). This ensures export-as-image's
ignoreElements (zoom-controls, pan-controls, cursor-hint, export-controls) will
correctly exclude these UI elements.
In `@apps/frontend/src/renderer/components/timeline/utils/export-as-image.ts`:
- Around line 221-225: Replace the DOM removal call that uses
document.body.removeChild(link) with the modern element.remove() API: locate the
code that appends and clicks the download anchor (the variable named link in
export-as-image.ts where you call document.body.appendChild(link); link.click();
document.body.removeChild(link);) and change the final call to link.remove() so
the element removes itself without needing the parent reference.
In `@guides/VISUAL-BUILD-TIMELINE.md`:
- Around line 62-77: The fenced code block showing the component structure in
VISUAL-BUILD-TIMELINE.md lacks a language specifier; edit the fence around the
timeline/ tree (the block that lists BuildTimeline.tsx, PhaseSwimLane.tsx,
SubtaskBlock.tsx, etc.) to add a language token such as "text" or "plaintext"
(e.g., change ``` to ```text) so Markdown processors render it consistently and
improve accessibility.

Return translatable error keys instead of hardcoded English strings.
Lines 174 and 178 embed user-facing error strings that get rendered directly in the timeline UI without translation. The component renders these at {error} without applying the t() function, leaving localized users seeing English messages.
Return an error code/key from the hook and translate it in the component where it's rendered (BuildTimeline.tsx). Follow the pattern used for the error label: translate the message in the component using t() with the appropriate i18n key from the timeline namespace.
As per coding guidelines: "All user-facing text must use i18n translation keys from react-i18next with format namespace:section.key. Never use hardcoded strings in JSX/TSX. Update all language files (minimum: English and French) when adding new text."

Hit-testing applies zoom twice.
calculatePhaseLayout() / calculateSubtaskLayout() already return zoomed coordinates and dimensions, but these helpers pass them through timelineToScreen() and multiply width/height by zoom again. At any zoom other than 1, the clickable bounds drift away from the rendered blocks.

In general, to fix an "unused variable/function" issue, either remove the unused element or start using it meaningfully. Here, the best fix without changing existing functionality is to remove the updateViewState callback because it's not used anywhere and its logic is redundant with the useEffect that already calls onViewStateChange on every viewState change.
Concretely, in apps/frontend/src/renderer/components/timeline/hooks/useTimelineLayout.ts, delete the entire updateViewState definition block (the JSDoc comment and the const updateViewState = useCallback(...) hook) around lines 85–95. No other code changes are needed, as there are no references to updateViewState, and we are not altering any other behavior.

In `@apps/frontend/src/renderer/components/timeline/BuildTimeline.tsx`:
- Around line 166-171: In handleWheel replace the object-spread update that
reads the stale viewState with a functional updater: call setViewState(prev =>
({ ...prev, zoom: newZoom, scrollX: newScroll.scrollX, scrollY:
newScroll.scrollY })), ensuring delta/focusX/focusY calculations remain before
this call; then remove viewState from the handleWheel dependency array so the
callback doesn't close over a stale value. This change targets the handleWheel
callback and the setViewState invocation to prevent lost updates during rapid
wheel events.
- Around line 205-210: In handleMouseMove replace the direct object-spread call
to setViewState with the functional updater form so you base the new state on
the latest previous state (e.g., setViewState(prev => ({ ...prev, scrollX:
dragStartRef.current.scrollX + deltaX, scrollY: dragStartRef.current.scrollY +
deltaY }))); also remove viewState from the dependency array of the useCallback
for handleMouseMove since the functional updater no longer relies on that
external variable. This prevents lost updates during rapid mouse movements and
keeps dragStartRef/current deltas intact.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineData.ts`:
- Line 14: Remove the unused SubtaskStatus import from the import list in
useTimelineData.ts: locate the import statement that includes "SubtaskStatus"
(alongside other imports) and delete only "SubtaskStatus" so the file no longer
imports an unused type; ensure the comma/spacing in the import list is adjusted
correctly so the remaining imports remain valid.
- Around line 82-84: The nested ternary used to compute status in
useTimelineData.ts is hard to read; extract the logic into a small helper (e.g.,
getStatus or computePhaseStatus) that takes isCurrentPhase,
executionProgress?.phase, completedSubtasks, and totalSubtasks and returns
'idle' | 'complete' | the current phase; replace the inline ternary with a call
to that helper to improve readability and testability while keeping the exact
decision logic intact.
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineExport.ts`:
- Around line 111-165: The export functions lack an early-exit guard to prevent
concurrent runs; add a check at the start of exportAndDownload (and mirror it in
exportToDataUrl and copyToClipboard) that returns immediately if isExporting is
true or exportRef.current is non-null (indicating an in-progress export) to
avoid overlapping exports, then only proceed to set exportRef.current = {
aborted: false } and setIsExporting(true) when the guard passes; ensure the
guard uses the same state variables used elsewhere (isExporting and exportRef)
and keeps the existing try/catch/finally behavior so cleanup still clears
exportRef and sets setIsExporting(false).
In `@apps/frontend/src/renderer/components/timeline/hooks/useTimelineLayout.ts`:
- Around line 61-301: Replace the duplicated wheel-zoom, drag-to-pan, and scroll
logic in BuildTimeline.tsx by importing and using the existing hook
useTimelineLayout: instantiate it with the timeline config, a ref to the
scroll/visual container (containerRef), and onViewStateChange/initialZoom as
needed; then forward returned handlers and values (handleWheel, handleMouseDown,
handleMouseMove, handleMouseUp, transformStyle, cursorStyle, viewState,
zoomIn/zoomOut/setZoom/pan/scrollTo) to the DOM elements and controls, and
remove the duplicated implementations in BuildTimeline so all behavior is driven
by useTimelineLayout (ensuring containerRef is attached to the same element
previously handling wheel/drag events).
- Around line 88-94: Remove the unused helper updateViewState from the hook:
delete the entire useCallback block named updateViewState and its dependency on
onViewStateChange, and replace any intended callers (none exist) by using
setViewState directly or calling onViewStateChange where needed; ensure there
are no remaining references to updateViewState in that module and keep the
existing setViewState((prev) => { const newState = { ...prev, ...updates };
onViewStateChange?.(newState); return newState; }) logic inline where necessary.
In `@apps/frontend/src/renderer/components/timeline/SubtaskBlock.tsx`:
- Around line 106-116: The inline status-based color selection logic inside the
SubtaskBlock component increases cognitive complexity; extract that logic into a
small helper (e.g., getSubtaskColors or selectColorsForSubtask) and replace the
inline conditional block (the code that currently computes colors based on
subtask.status around the SubtaskBlock function) with a single call to that
helper, passing subtask.status, agentType, and colors (DEFAULT_TIMELINE_COLORS)
as needed; ensure the helper returns the same color set used in the JSX so you
only change where colors are computed and keep rendering intact.
In `@apps/frontend/src/renderer/components/timeline/utils/export-as-image.ts`:
- Around line 326-333: The isClipboardAvailable function uses window which
limits environments; replace checks referencing window with globalThis for
broader compatibility (also guard that globalThis is defined where used). In the
function isClipboardAvailable, change the existence check from 'ClipboardItem'
in window to checking globalThis (e.g., 'ClipboardItem' in globalThis) and
ensure the top-level typeof globalThis !== 'undefined' is used alongside the
existing navigator and navigator.clipboard/write checks so the function works in
SSR/workers/Electron.
- Around line 341-344: The getOptimalScale function uses window.devicePixelRatio
which can break in non-browser or worker contexts; replace the window reference
with a safe globalThis lookup (e.g., const dpr = (typeof globalThis !==
"undefined" && globalThis.devicePixelRatio) ? globalThis.devicePixelRatio : 1)
inside getOptimalScale so it falls back to 1 when devicePixelRatio is
unavailable and preserves the existing Math.min(Math.ceil(dpr), maxScale)
behavior.

Use functional setViewState updater in handleWheel to prevent lost updates.
The handleWheel callback captures viewState from render time and uses object spread. During rapid wheel events, React batches updates, so later events may overwrite earlier ones instead of composing from the latest state.
🔧 Proposed fix
- setViewState({
- ...viewState,
- zoom: newZoom,
- scrollX: newScroll.scrollX,
- scrollY: newScroll.scrollY,
- });
+ setViewState((prev) => {
+ const newZoom = clampZoom(prev.zoom + delta * 0.1, config);
+ const newScroll = calculateScrollAfterZoom(
+ prev.scrollX,
+ prev.scrollY,
+ prev.zoom,
+ newZoom,
+ focusX,
+ focusY
+ );
+ return {
+ ...prev,
+ zoom: newZoom,
+ scrollX: newScroll.scrollX,
+ scrollY: newScroll.scrollY,
+ };
+ });Note: This requires moving delta, focusX, focusY calculations before the setViewState call (they're already there), and removing viewState from the dependency array since it won't be used in the callback body.

Consider adding early exit guard for concurrent exports.
The hook correctly tracks isExporting state, but based on BuildTimeline.tsx (line 122-128), the handleExport callback doesn't check this state before invoking exportAndDownload. If the UI button's disabled state briefly desyncs (e.g., during rapid clicks before React re-renders), concurrent exports could be triggered.
🛡️ Suggested defensive guard
const exportAndDownload = useCallback(
async (element: HTMLElement) => {
if (!enabled) {
throw new Error('Export functionality is disabled');
}
+ // Prevent concurrent exports
+ if (isExporting) {
+ return;
+ }
+
// Reset state
setIsExporting(true);Apply the same pattern to exportToDataUrl and copyToClipboard.

🧹 Nitpick | 🔵 Trivial
Consider using this hook in BuildTimeline.tsx to reduce code duplication.
BuildTimeline.tsx reimplements the same wheel-zoom, drag-to-pan, and scroll handling logic that this hook provides (see context snippets 1-4 in the relevant code snippets). The hook supports both left and middle mouse button drag with proper threshold handling, while BuildTimeline only supports middle mouse button without threshold protection.
Using useTimelineLayout in BuildTimeline would:
- Consolidate zoom/pan logic in one place
- Add left-mouse drag support
- Add click-vs-drag threshold protection
- Improve maintainability

remove the duplicated implementations in BuildTimeline so all behavior is driven

Remove unused updateViewState helper.
The updateViewState function is defined but never called within the hook, as confirmed by static analysis.
🧹 Proposed fix

- const updateViewState = useCallback((updates: Partial<TimelineViewState>) => {
- setViewState((prev) => {

Consider extracting status-based color selection to reduce cognitive complexity.
SonarCloud flags cognitive complexity of 20 (threshold 15). The component is well-structured with extracted helpers, but the inline color selection logic (lines 127-135) combined with the extensive JSX contributes to complexity. Consider extracting the color scheme selection:
♻️ Optional refactor to reduce complexity
+/**
+ * Get color scheme based on agent type and subtask status
+ */
+function getColorScheme(
+ colors: TimelineColorScheme,
+ colorKey: keyof TimelineColorScheme,
+ status: 'pending' | 'in_progress' | 'completed' | 'failed'
+): TimelineColorScheme[keyof TimelineColorScheme] {
+ if (status === 'failed') return colors.error;
+ if (status === 'pending') return colors.inactive;
+ return colors[colorKey];
+}
+
export const SubtaskBlock = memo(function SubtaskBlock({
// ...props
}: SubtaskBlockProps) {
// ...
const colorKey = getAgentColorKey(agentType);
const subtaskStatus = getSubtaskStatus(subtask);
const isCurrent = subtask.id === currentSubtaskId;
- // Select color scheme based on status
- let colorScheme = colors[colorKey];
- if (subtaskStatus === 'failed') {
- colorScheme = colors.error;
- } else if (subtaskStatus === 'completed') {
- colorScheme = colors[colorKey]; // Use agent color for completed
- } else if (subtaskStatus === 'pending') {
- colorScheme = colors.inactive;
- }

106 - 116, The inline status-based color selection logic inside the SubtaskBlock
component increases cognitive complexity; extract that logic into a small helper
(e.g., getSubtaskColors or selectColorsForSubtask) and replace the inline
conditional block (the code that currently computes colors based on
subtask.status around the SubtaskBlock function) with a single call to that
helper, passing subtask.status, agentType, and colors (DEFAULT_TIMELINE_COLORS)
as needed; ensure the helper returns the same color set used in the JSX so you
only change where colors are computed and keep rendering intact.

SonarCloud suggests preferring globalThis over window. While window works in Electron/browser contexts, globalThis is more portable for potential SSR or worker contexts.
