# 4.9 — Log rejected /api/exec input (GREEN)

Phase: 4 — Terminal (Surface C)
Stage: GREEN

- [x] Every rejected `/api/exec` input logged (server console)

Done — `console.warn` on every reject branch in [app/api/exec/route.ts](../app/api/exec/route.ts). Mock only: plain console output, not the structured/shipped logging pipeline a real backend needs — see [REQUIREMENTS.md](REQUIREMENTS.md).
