├── CLAUDE.md          + a marked protocol block (v3)
├── COORD.md           one honest line per prompt, append-only
├── COORD-AGENTS.md    one row per finished lane, auto-written
├── briefs/agent-*.md  every lane's exact commission, banked
├── spend/ledger.md    every model spend, receipted
├── gates/ACTIVE.md    (optional) runnable done-when contracts
└── START-HERE.md …    the handoff a cold reader can follow
