overhaullisted

# Overhaul Turn a frontier model's limited time into maximum leverage: the strongest model available architects; cheaper models execute. The output of every expensive phase is an **executable artifact** that survives the session, so execution never requires the architect to be present. ## Core contract 1. **Never burn architect time on reconnaissance or mechanical work.** Reconnaissance is fanned out to the cheapest capable model. The architect only reads syntheses and produces plans. 2. **Every phase emits a file.** If a phase's result exists only in conversation, the phase is not done. Artifacts live in `.overhaul/` at the repo root. 3. **All destructive work happens on a dedicated branch** named `overhaul/<yyyy-mm-dd>`. Deletion is aggressive on the branch; the human reviews at the PR. Never commit to the default branch directly. 4. **Empirical proof before merge.** No workstream is complete until its verification command passes (tests, typecheck, build — whatever the plan defines as proof). 5. **The repo must end smarter, not just cleaner.** Lessons learned during execution are catalyzed into rules/validators (see Phase 5). ## Model roles Detect which model is running the current session and slot into the right role. If the session model is the architect-tier model, do Phases 1–2 and STOP — hand off. If it is an executor-tier model given a workstream spec, skip to Phase 4. | Role | Tier (examples) | Does | Never does | |---|---|---|---| |
