r213 VSIL Editor — AI Summary

Status: ✅ All green · 36/36 r213 unit · 31/31 r213 Playwright · 0 regressions

Branch: feat/id9-r213-vsil-editor @ 3d51f99 (pushed to origin)

Base: feat/id9-r212-chrome-consolidation @ 71e6b43

TL;DR

• r213 replaces the r212 timeline tile placeholder with a world-class VSIL Editor — 8 React components, 1,873 LoC.
• All 8 components integrate with r206 StudioContext, r207 mounts (PreviewHostVSIL/InspectorHost/CompositionGraphHost), and r208 EditBar.
• 216/216 total tests pass: 141 unit + 75 Playwright.
• 0 iframes, 0 postMessage in r213 source.
• a788 READ-ONLY invariant preserved via Lock/Edit toggle.

The 8 components

1. ToolStrip (148 LoC) — 6 tools (move/crop/brush/text/shape/transform)

2. LayersPanel (275 LoC) — 4 layers, eye/lock/up/down

3. Canvas (225 LoC) — 16:9 viewport, zoom 25-400%, surface/asset tags

4. Inspector (323 LoC) — properties + transforms + metadata, READ-ONLY by default

5. Timeline (313 LoC) — 5 states, 8 keyframes, 4 transitions, play/pause/scrub

6. PresetBrowser (207 LoC) — 12 presets (4 scenes, 3 compositions, 5 templates)

7. Composer (176 LoC) — 5-node graph, 5 edges

8. VSILEditor (206 LoC) — shell that composes them all + Lock/Edit toggle

What this means

The operator opens the SideChrome (via the workspace icon), clicks the timeline tile, then clicks Edit. The world-class VSIL Editor mounts. The Editor has 8 components arranged in a 2D grid: tool strip on top, layers on the left, canvas in the center, inspector on the right, presets + timeline + composer on the bottom. The Inspector is read-only by default (a788) and the operator can click Lock → Edit to enable writes. The r207 mounts still render (in the corresponding SideChrome tiles) and the r208 EditBar still works for the non-timeline tiles.

The 3 critical r213 details

1. Lock → Edit toggle (a788): r212's Lock/Edit toggle is preserved. Lock mode shows a hint; Edit mode mounts the Editor with initialReadOnly={false}.

2. r207 mount preservation via hidden mount-hosts: The PreviewHostVSIL/InspectorHost/CompositionGraphHost mounts are preserved (per spec) and pick up r206 bus events via hidden mount-host containers in the Canvas/Composer.

3. r206 context bug fix: Stub factories now get a forward-ref { state, getCtx } bag so ensureHostMounted can find ctx.bus (the r208-era { state } as any cast left ctx.bus undefined and crashed the lazy-mount flow).

Test results

• 24/24 r207 unit + 27/27 r208 unit + 27/27 r210 unit + 27/27 r212 unit + 36/36 r213 unit = 141/141 unit
• 31/31 r213 Playwright + 44/44 r212 Playwright = 75/75 Playwright
• Total: 216/216

What's next

1. Operator review of the r213 Editor in the dev server (port 5280)

2. Operator decision on merge (r212 + r213 = full ID9 chrome + Editor)

3. VSIL Editor polish based on operator feedback

4. Production deploy — npm run build + scp to 185.249.73.178?

Open questions

1. Merge r213 to main now, or wait for r214 polish?

2. Production deploy — npm run build + scp to 185.249.73.178?

3. VSIL Editor polish — keyboard shortcuts? drag-to-zoom? additional tools?

4. Canvas ↔ Preset wiring — should the Editor wire a real VSIL scene to the Canvas, or keep the "no scene bound" empty state?
