# Test Report — Issues #7 & #8 Fix

**Date:** 2026-06-29
**Task:** Fix loadFromState race condition (#7) and Plugin Context stale closure (#8)

## Files Modified
- `frontend/src/App.tsx` — refs for PluginContext, loadFromState guard
- `frontend/src/crdt/YjsDocument.ts` — loadFromState guard against empty data clearing maps

## Test Results

### 1. TypeScript Type Check (`tsc --noEmit`)
```
$ npx tsc --noEmit
EXIT_CODE=0
```
**Result:** PASS — 0 errors

### 2. Vite Build
```
$ npx vite build
✓ 341 modules transformed.
✓ built in 8.04s
EXIT_CODE=0
```
**Result:** PASS — build successful

### 3. Grep Verification — useRef refs in App.tsx
```
182:  const elementsRef = useRef(elements);
184:  const layersRef = useRef(layers);
186:  const blocksRef = useRef(blocks);
188:  const groupsRef = useRef(groups);
190:  const bgConfigRef = useRef(bgConfig);
192:  const activeLayerIdRef = useRef(activeLayerId);
```
**Result:** PASS — all refs declared

### 4. Grep Verification — elementsRef.current in PluginContext
```
134:      getElements: () => elementsRef.current,
135:      getLayers: () => layersRef.current,
136:      getActiveLayerId: () => activeLayerIdRef.current,
```
**Result:** PASS — PluginContext getters use refs

### 5. Grep Verification — loadFromState guard checks non-empty data
```
App.tsx:286:        const hasContent = data.elements.length > 0 || data.layers.length > 0 || data.blocks.length > 0 || groups.length > 0 || bgConfigs.length > 0;
App.tsx:287:        if (collab.status === 'connected' && hasContent) {
YjsDocument.ts:127:      if (state.elements.length > 0) {
YjsDocument.ts:133:      if (state.layers.length > 0) {
YjsDocument.ts:139:      if (state.blocks.length > 0) {
YjsDocument.ts:145:      if (state.groups && state.groups.length > 0) {
YjsDocument.ts:151:      if (state.bgConfigs && state.bgConfigs.length > 0) {
```
**Result:** PASS — guards in both files

## Smoke Test
- App builds successfully with `vite build` (341 modules, 8.04s)
- No TypeScript errors
- No `any` type used
- No existing PluginContext fields removed

## Summary
All test criteria met. Both issues fixed.
