Add 'Producing a test build' (android:init -> android:sync -> assembleDebug ->
adb install) to the ESCROW.md checklist, plus the two-account requirement. The
mint-touching paths still need a real device run.
Add a step-by-step Android verification checklist to ESCROW.md (preconditions,
advertise key -> buyer escrow -> seller redeem -> refund -> guard rails) and
point to it from the Status section and AGENTS.md. Escrow stays unverified until
every box passes on a device with tiny amounts.
Real, oracle-free escrow built on Cashu P2PK with a locktime + refund key:
buyer locks funds to the seller; seller redeems on delivery; the buyer can
reclaim after the deadline. Locked (not plain) tokens are what make the
cashu_token on a public 31872 safe.
- src/lib/cashuEscrow.ts: pubkey normalisation (x-only -> compressed), P2PK
policy builder, offline token inspection (amount/mint/locktime/refund), and
an injectable createEscrowToken mint flow (quote -> pay -> mintProofs{p2pk})
- 15 unit tests incl. the mint orchestration against a fake wallet
- Protocol: advertise a 'cashu_escrow' pubkey in kind 0 (NIP.md); token rides
the existing 31872 cashu_token tag
- ESCROW.md: design, threat model, status, limitations
- AGENTS.md: project map + docs index updated
Wallet UI (cashu-ts + payment rail + profile publish) is native-only and still
needs on-device verification.
