v1.0.13 — freeze gate: chat is not the Goal Contract
Stage 1 idea requests list a short menu and wait; they do not implement. Chat `setuju` does not freeze AC. Every user-visible grill decision must be a numbered AC in the Goal Contract file.
Judge PASSes only against that file (including CONTEXT_ISOLATION_ONLY). ITERATE if evidence is source-grep or a different artifact than the AC names (for example a /tmp build vs the sample the user opens).
After install: `npx ai-engineering-loop@1.0.13 sync-hosts` then start a new session.
