# ID9 — r208 Implementation Report — AI Summary

**Date**: 2026-08-30 | **Source**: a803 (full, 11 KB)
**Branch**: `feat/id9-r208-integration` | **Commit**: `4d8fd92` | **Repo**: `avidtech6/vibecoder-standalone`
**Base**: `feat/id9-r207-mount @ aabe651` (r206 at `clean/baseline-plus-wdm @ 0746358`)

---

## TL;DR (5 bullets)

- **6 new files + 2 LoC diffs to host-boot.js shipped to `feat/id9-r208-integration @ 4d8fd92`**, pushed to origin. 1,028 LoC added. All 6 deliverables from the r208 plan are present, with all 3 operator decisions (Q1: 4 ops + presets, Q2: both VSIL + Dev, Q3: deploy after Playwright) implemented.
- **27/27 r208 tests pass + 24/24 r207 tests still pass = 51/51 combined**. 10 test sections cover: Gallery→Preview cascade, bridge failure handling, all 4 region ops (Q1), preset application (Q1), no-active-region, setBusy lifecycle, click count, preview:vsil with surface-targeting, no iframe / no postMessage, per-instance state.
- **Typecheck clean for all r207 + r208 files**. The full-project tsc shows pre-existing errors in `src/agent/{core,plan}.ts` (NOT part of r208 — present on `c8a8c6b` / `0746358` before this commit).
- **The r202 iframe is GONE**. The `replace-iframe-vsil.js` monkey-patches `mgr.addPanel` to detect and replace any panel content containing an iframe pointing to `vibescope.freshvibeapps.com` with a plain div that the r208 orchestrator populates with the 3 r207 mounts. Zero source-conflict risk vs a hardcoded edit.
- **All r206 + r207 invariants honored**: nested capability bag (`ctx.gallery.asset.bind`, `ctx.inspector.region.transform`), window-level bus (`ctx.bus.emit`), lazy-mount via `composition:host-mounted`, surface-targeting via `targetSurface`, READ-ONLY inspector (`InspectorHost.readOnly={true}` by default; only flips to `false` when EditBar is mounted), capabilities return `{ ok, reason }`, 8 of 33 r206 events consumed.

## What was implemented

### `GalleryPreviewBridge.ts` (123 LoC)
- Class with `onCardClick({ cardId, assetId, surface, source })` method
- Calls `ctx.gallery.asset.bind({ assetId, source })` which cascades to `ctx.inspector.vsil.asset.bind` via r206 stub
- `emitPreviewRequest({ assetId, surface, mode })` dispatches `preview:vsil` with `targetSurface: surface` (Q2 surface-targeting)
- Tracks `clickCount` + `lastClickedCard` for observability
- Exposed as `window.__fvcmsGalleryPreviewBridge`

### `CompositionHostMount.tsx` (141 LoC)
- Tabbed UI: 4 tabs (`preview` / `inspector` / `composition` / `edit`)
- 5-surface state machine UI: buttons for `main` / `working` / `draft` / `preview` / `origin`
- Mounts all 3 r207 hosts: `<PreviewHostVSIL>`, `<InspectorHost>`, `<CompositionGraphHost>`
- Mounts `<EditBar>` when `tab === 'edit'`
- `data-r208-host`, `data-surface`, `data-edit-mode`, `data-tab` attributes for Playwright

### `EditBar.tsx` (167 LoC)
- 4 transform buttons: `translate` / `scale` / `rotate` / `reset` (Q1)
- Preset list (auto-loaded from `ctx.inspector.region.list`)
- `setBusy(true/false)` lifecycle around each capability call
- `lastResult` displayed in a `data-edit-result` div (success/fail with reason)
- All writes go through `ctx.inspector.region.{transform,applyPreset}` (r206 capabilities, returning `CapabilityResult<{ region: VSILRegion }>`)

### `r208-integration.ts` (150 LoC)
- Boot orchestrator: `bootR208Integration()` is the idempotent entry point
- Sets `window.__fvcmsStudioContext` (r206 singleton) + `window.__fvcmsGalleryPreviewBridge` + `window.__fvcmsBootR208Integration`
- Renders the 3 hosts into `#fvcms-vsil-panel-mount` and the EditBar into `#fvcms-dev-panel-edit-bar-slot`
- Exposed on `window.__fvcmsBootR208Integration` for the host-boot Step 6.5 call
- Singleton pattern: `_booted` flag prevents double-init

### `replace-iframe-vsil.js` (76 LoC)
- `patchOpenVsilPanel()` exports a function that monkey-patches `mgr.addPanel`
- Detects panels whose content includes an iframe pointing to `vibescope.freshvibeapps.com`
- Replaces the iframe with a plain div `#fvcms-vsil-panel-mount`
- One-shot: only patches the first matching call, passes subsequent calls through unmodified

### `__tests__/r208-integration.test.ts` (371 LoC)
- 10 test sections, 27 assertions, 27/27 pass
- Plain-Node test runner pattern (per `src/cms/app-fragments/ai-agent/v02.test.js`)
- Run with: `npx tsx src/host/integration/__tests__/r208-integration.test.ts`

### `src/host/host-boot.js` (2 LoC diffs)
- **Diff 1**: Lines 803-838 (`openVsilPanel`) — replaced iframe creation with `wrap.id = 'fvcms-vsil-panel-mount'` + `wrap.style.cssText = 'width:100%;height:100%;background:#0e0e16;overflow:auto;'` + added `if (typeof window.__fvcmsBootR208Integration === 'function') window.__fvcmsBootR208Integration();` after `mgr.addPanel(...)`
- **Diff 2**: New `// 6.5. r208: Bind the 3 r207 mounts to the operator flow` step comment (no code, just a marker)

## What was NOT done (per scope)

- ❌ No `pact/` edits
- ❌ No `<iframe>` in any r208 file (Test 9 verifies; the iframe was REMOVED from host-boot.js)
- ❌ No `postMessage` in any r208 file (Test 9 verifies)
- ❌ No new event types
- ❌ No new capability types
- ❌ No InspectorCard migration in freshvibestudio (a788) — requires cross-repo package alias, deferred
- ❌ No Playwright smoke in this session — operator decided "deploy after Playwright" (Q3), so Playwright is the gate
- ❌ No VPS deploy — deferred to after Playwright

## What's at risk

1. **Playwright smoke gate** — the full interaction loop has 5+ steps. Playwright must exercise all of them before VPS deploy. The 10 r208 unit tests cover the bus events + state transitions, but the live 3-mount mount/unmount cycle needs a browser smoke.
2. **Dev Panel Inspector tab** — the actual Dev Panel has 4 sub-tiles (scene/inspector/composer/timeline) per r202. r208 only handles the inspector tile; the other 3 are r202 stubs. Operator may want to fill those in next.
3. **OS Header surface pills** — the pills dispatch `surface:activated`, but r208 mounts at Step 6.5 (before pills are interactive). The 5-surface state machine UI in `CompositionHostMount` is rendered, but doesn't actually dispatch the event. **This is a known gap** — the host's existing pills do the dispatch, but the in-panel state machine is read-only display.

## How to verify (operator)

```bash
# 1. Check the commit on origin
GIT_SSL_NO_VERIFY=1 git -C /workspace/vibecoder-standalone ls-remote origin feat/id9-r208-integration
# Expected: 4d8fd92 r208: end-to-end integration of r207 mounts into operator flow

# 2. Run the tests (in the r208 worktree)
cd /workspace/vibecoder-standalone-r208
npx tsx src/host/integration/__tests__/r208-integration.test.ts
# Expected: 27 passed, 0 failed

# 3. Run the r207 tests (regression)
npx tsx src/host/mounts/__tests__/mounts.test.ts
# Expected: 24 passed, 0 failed

# 4. Typecheck just the r208 files
npx tsc --noEmit 2>&1 | grep "src/host/integration/"
# Expected: no output (clean)
```

## 3 open questions (all decided by operator before this commit)

1. **Q1 (Edit scope)**: ✅ all 4 region ops (translate/scale/rotate/reset) + presets
2. **Q2 (EditBar placement)**: ✅ both VSIL panel + Dev Panel slot
3. **Q3 (VPS deploy timing)**: ✅ after Playwright smoke passes
