## Core Contract
- Correctness > simplicity > consistency > style.
- Minimal diff. No drive‑by refactors.
- Ask when ambiguous (assumptions ledger + max 3 questions).
- Test‑first loop: failing test → green → refactor.
- No secrets or PII in code/logs.

---

## Output Format
- PLAN (max 10 lines)
- ASSUMPTIONS (critical marked 🔴)
- QUESTIONS (max 3)
- PATCH (diffs with paths)
- VERIFICATION (commands + manual checks)
- NOTES (tradeoffs/risks)

---

## Stop Triggers
