+# AEG-X-002 — Frontend Typecheck Emit Remediation
+
+- **WBS / Requirement:** AEG-X-002 / REQ-PLAT-TOOL
+- **Classification:** behavior-preserving frontend toolchain refactoring
+- **Selected on:** 2026-08-08
+
+## Source / Assumption / Unknown / Decision Required
+
+- **Source:** `frontend/package.json`, `frontend/tsconfig.json`, and the tracked `*.vue.js` changes produced by the current build command.
+- **Assumption:** Vite, not TypeScript, is the approved JavaScript production emitter. Type checking must not modify tracked source-adjacent JavaScript files.
+- **Unknown:** none for this local toolchain correction.
+- **Decision Required:** none. The command retains the same type validation and Vite production build; it removes only unintended TypeScript emit.
+
+## Change
+
+- Replace `vue-tsc -b && vite build` with `vue-tsc --noEmit && vite build`.
+
+## Acceptance Evidence
+
+- `pnpm build` completed successfully on 2026-08-08; the preserved output is `evidence/AEG-X-002/frontend-build-noemit_20260808.log`.
+- Before/after SHA-256 comparison of the previously dirtied tracked `*.vue.js` files found no changed file after the no-emit build.
+- Full frontend regression was executed before this command-only change: 26 files / 57 tests passed.
+- The build still reports a 501.14 kB gzip initial JavaScript chunk. It is recorded as a separate performance concern, not hidden by changing Vite's warning limit.
+
+No provider, API, schema, runtime configuration value, policy, or feature semantics changes.

+- Using dynamic import() to code-split the application
+- Use build.rolldownOptions.output.codeSplitting to improve chunking: https://rolldown.rs/reference/OutputOptions.codeSplitting
+- Adjust chunk size limit for this warning via build.chunkSizeWarningLimit.
