+## Development Workflow
+
+### Package Changes Testing
+
+When making changes to `packages/` directory and testing with `examples/`:
+
+1. **Vite dev server auto-reloads**: The dev server (`bun run dev`) automatically reloads changes in `packages/` when you access the example pages
+2. **Verify changes took effect**: Modify `DEV_MODE_TS` in `packages/manage/router/index.vue` - this string is displayed at `.el-menu .menu-footer` (bottom of sidebar menu). Changing it forces the app to refresh.
+3. **Build before finishing**: Run `bun run build:lib` to ensure the library builds correctly with your changes
+
+```typescript
+// In packages/manage/router/index.vue - change this string to force refresh
+const DEV_MODE_TS = "2026-03-26T03:50:00.000Z";  // Update timestamp to force reload
+```
+
+### Quick Test Cycle
+
+```bash
+# 1. Make changes to packages/
+# 2. Dev server auto-reloads when accessing example pages
+# 3. Modify DEV_MODE_TS in packages/manage/router/index.vue if changes don't appear
+# 4. Run build when done to verify
+bun run build:lib
+```
+
+### Browser Automation with agent-browser
+
+When using `agent-browser` for testing:
+
+**DO**: Use CSS selectors with `wait` instead of fixed timeouts
+```bash
+# Good - waits for element to appear
+agent-browser wait ".el-table-v2__row" && agent-browser snapshot
+
+# Bad - arbitrary timeout, may be too short or waste time
+agent-browser wait 3000
+```
+
+**DO**: Check console for errors after page interaction
+```bash
+agent-browser click "@e1" && agent-browser console
+```
+
+**DO**: Navigate with hash routes properly
+```bash
+# Hash-based SPA routes need explicit navigation
+agent-browser navigate http://localhost:5173/#/table-v2
+```
+
+**Common wait patterns**:
+- `agent-browser wait --load networkidle` - for page navigation
+- `agent-browser wait ".my-selector"` - for element appearance
+- `agent-browser wait --url "**/pattern"` - for URL changes

+## Common Mistakes / Gotchas
+
+### el-table-v2 probe row timing
+
+When using a probe row to dynamically measure row height for el-table-v2's virtual scrolling:
+
+**Problem**: Using a single `requestAnimationFrame` causes inconsistent row heights (first 3 rows taller than rest).
+
+**Cause**: el-table-v2's virtual scroller calculates positions based on `estimatedRowHeight`, but a single frame isn't enough for it to fully settle.
+
+**Solution**: Use TWO `requestAnimationFrame` calls before measuring:
+```typescript
+await nextTick();
+await new Promise(resolve => requestAnimationFrame(resolve));  // Frame 1
+await new Promise(resolve => requestAnimationFrame(resolve));  // Frame 2 - el-table-v2 now settled
+const height = probeRowRef.value?.offsetHeight;
+```
+
+**Verification**: All rows should have identical heights and consistent spacing.
