HARD GATE — HARD GATE — Simulations are hypothetical. Do NOT use sim results to make production decisions without validation on real agents. Sims help discover gaps, not replace testing.

Two roles, isolated contexts (no shared state with BUILD agent):

1. Mock User — follows Verification Script; reports UX gaps in plain language.
2. Auditor — checks CONVENTIONS.md, security checklist, test coverage; structured pass/fail.

1. Read story Verification Script + changed files diff.
2. Spawn Mock User: step through UAT script; log failures.
3. Spawn Auditor: run audit-code checklist cold.
4. Write specs/SIMULATION-<feature>.md with both reports.
5. Failed items → respond-review or plan-work gaps — do not skip human review.

→ verify: ls specs/SIMULATION-*.md 2>/dev/null | head -1 | grep -q . && grep -c "Mock User\|Auditor" specs/SIMULATION-*.md | awk '{if($1>=2) print "OK"}' || echo "MISSING: no simulation files"
