The five verbs

Step	Verb	Standard
1	quote	SEP-38 POST /quote
2	comply	SEP-10 auth + SEP-12 KYC handoff
3	open	SEP-31 POST /transactions
4	settle	native Stellar payment of the bridge asset
5	reconcile	SEP-31 GET /transactions/:id

A persisted state machine drives created → quoted → compliant → opened → settling → settled → reconciled → completed, with recovering → refunded / held for failures. Every transition is logged, audited, and counted.
