## CF11-006 — Execution History Panel UI ✅ COMPLETE

**Status:** Done  
**Completed:** 2026-02-18

### What was built

- `ExecutionHistoryPanel.tsx` — main panel component (registered in sidebar at order 8.8)
- `ExecutionHistoryPanel.module.scss` — panel styles using design tokens
- `hooks/useExecutionHistory.ts` — fetches paginated execution list with filters
- `hooks/useExecutionDetail.ts` — fetches single execution with full step data
- `components/ExecutionList/` — `ExecutionList.tsx`, `ExecutionItem.tsx`, SCSS
- `components/ExecutionFilters/` — `ExecutionFilters.tsx`, SCSS (status + date range)
- `components/ExecutionDetail/` — `ExecutionDetail.tsx`, `NodeStepList.tsx`, `NodeStepItem.tsx`, SCSS
- `tests/cloud/ExecutionHistoryPanel.test.ts` — 15 unit tests (formatDuration, formatRelativeTime, buildExecutionQuery)

### Key decisions

- `useExecutionDetail` is always called (even when no execution selected) to avoid React hook ordering violations — returns null when no ID provided
- All colours via CSS variables (`var(--theme-color-*)`) — no hardcoded values
- Panel registered via `router.setup.ts` at order 8.8

## CF11-007 — Canvas Execution Overlay ✅ COMPLETE

**Status:** Done  
**Completed:** 2026-02-18

### What was built

**React components** (`src/editor/src/views/CanvasOverlays/ExecutionOverlay/`):

| File | Purpose |
|------|---------|
| `ExecutionOverlay.tsx` | Main overlay — header, transform container, badge list, popup, timeline |
| `ExecutionNodeBadge.tsx` | Status badge rendered at each node's canvas-space position |
| `ExecutionDataPopup.tsx` | Floating popup showing input/output/error data for selected node |
| `ExecutionTimeline.tsx` | Fixed scrubber bar — Prev/Next buttons, range input, step dots |
| `index.ts` | Barrel exports |
| `*.module.scss` | SCSS for each component (design tokens only) |

**Integration:**

- `nodegrapheditor.html` — added `#execution-overlay-layer` div
- `nodegrapheditor.ts` — added `executionOverlayRoot` field, `renderExecutionOverlay()`, `updateExecutionOverlay()`, wired into `render()` and `setPanAndScale()`
- `ExecutionHistoryPanel.tsx` — added `handlePinToCanvas` callback that emits `execution:pinToCanvas` via `EventDispatcher.instance`

**Tests** (`tests/cloud/ExecutionOverlay.test.ts`):

- 20 unit tests covering: `overlay_formatDuration`, `statusIcon`, `buildNodeStepMap`, `badgePosition`, `popupPosition`
- Registered in `tests/cloud/index.ts`

### Architecture

```
ExecutionHistoryPanel
  └─ "Pin to Canvas" button
       └─ EventDispatcher.emit('execution:pinToCanvas', { execution })
            └─ ExecutionOverlay (React, mounted in #execution-overlay-layer)
                 ├─ Header bar (fixed) — workflow name, status, Unpin button
                 ├─ Transform container (canvas-space, follows pan/zoom)
                 │    ├─ ExecutionNodeBadge × N (one per node in step map)
                 │    └─ ExecutionDataPopup (shown when badge clicked)
                 └─ ExecutionTimeline (fixed) — scrubber, step dots, Prev/Next
```

### Key decisions

- Overlay uses same CSS transform pattern as `HighlightOverlay` — parent container gets `scale(zoom) translate(x, y)` so all children use raw canvas coordinates
- `buildNodeStepMap` uses last-write-wins for repeated nodeIds (a node can appear in multiple steps; we show its latest state up to `currentStepIndex`)
- `useEventListener` hook used for all EventDispatcher subscriptions (per `.clinerules`)
- `overlay_formatDuration` prefixed in tests to avoid name collision with CF11-006 test bundle

### Manual verification steps

1. `npm run dev` → open editor
2. Open Execution History panel (sidebar)
3. Click an execution to open detail view
4. Click "Pin to Canvas" button
5. Verify: header bar appears at top of canvas with workflow name + status
6. Verify: node badges appear at each node's position (colour-coded by status)
7. Verify: clicking a badge opens the data popup with input/output/error data
8. Verify: timeline scrubber at bottom — Prev/Next navigate through steps
9. Verify: badges update as you scrub through steps
10. Verify: "Unpin" button dismisses the overlay
11. Verify: pan/zoom updates badge positions correctly
