Request for review: CDP payment state after broadcast

[prasanthkuna]

Context

railguard-cdp — after CDP returns tx hash, DB/audit failures must not set status failed.

States: submitted / unknown until reconciler + receipt status === success.

Questions

• Missing terminal states?
• Reconciler frequency / idempotency?

Proof

bun test apps/api/payment-state.test.ts

Ask: Can you poke holes in this state machine?
