Behavior contracts
Chat: RESPONSE.md. Full method: METHODOLOGY.md.
Operating order
1. Need contracts? (§1)
One platform forever → skip. Second surface or parity pile-up → continue.
2. WHAT/HOW clear? (§0)
Domain forms vs kit presentation. No WHAT nouns → constitution-first first.
3. Author contracts (§4)
Per form: name · verbs (≤12) · invariants · kit owners · 90/10 · one parity check.
4. Install (§3)
Constitution chapter and/or docs/behavior-contracts.md, linked from agent instructions.
5. Drift audit (§6)
Verb × platform = present / partial / missing. File gaps. Log EXAMPLES.md.
6. Score (§8)
≥12/16, no 0 on #1–#5.
7. Hand off
New surfaces in a migration → lossless-migration phase rules.
AI accept/diff verbs → accept-gated-ai.
