+# Build and Fix
+
+Incrementally fix TypeScript and build errors:
+
+1. Run `pnpm typecheck` or `pnpm build` (this repo uses pnpm + Turbo + Vite)
+
+2. Parse error output:
+   - Group by file
+   - Sort by severity
+
+3. For each error:
+   - Show 5 lines of context
+   - Explain the issue
+   - Apply a minimal fix
+   - Re-run the failing command
+
+4. Stop if:
+   - The fix introduces new errors
+   - The same error persists after 3 attempts
+   - The user asks to pause
+
+5. Show summary of fixed / remaining / new errors
+
+Fix one error at a time. Do not refactor. Invoke **build-error-resolver** when useful.
