Next batch from MARKETPLACE_FLOW_AUDIT.md: - bolt11.ts: getBolt11Expiry / isBolt11Expired; usePayPaymentPointer refuses an expired invoice before paying (a lapsed offer invoice used to fail deep in the wallet with a confusing error). - PayWithSats shows unsupported pointer kinds (creq/clink) as unavailable up front instead of enabling a button that fails after the click. - useTradeAttestations: verify events (onlyVerified) and keep the newest per (author, kind, d), so a newer s=revoked supersedes a stale valid copy; useTradeReputation no longer trusts unverified relay events. - EscrowRequestDialog persists the minted token locally before publishing (lib/pendingEscrow.ts), so a failed send cannot strand the locked funds.

/**
|
|
* Device-local record of an escrow token that was minted (funds locked) but not
|
|
* yet confirmed on a relay.
|
|
*
|
|
* WHY: escrow creation mints P2PK-locked proofs and then publishes a kind-31872
|
|
* request carrying the token. If the publish fails, the token lived only in an
|
|
* in-memory variable and the locked funds were unrecoverable. Persisting it here
|
|
* before the publish keeps the buyer able to recover/refund.
|
|
*
|
|
* The token is a bearer instrument, but it is P2PK-locked to the seller with the
|
|
* buyer's refund key — so storing it is safe and is exactly what protects the
|
|
* buyer if the send does not go through.
