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.
- getPaymentHashFromBolt11 (bolt11.ts, dependency-free; matches the BOLT11 spec
test vector) + verifyPreimage (sha256(preimage) === payment_hash).
- usePayPaymentPointer captures the preimage from NWC/WebLN/melt and returns a
PaymentReceipt; PayWithSats.onPaid carries it; stored device-locally so the
later confirm step attaches it; publishTrade writes
['proof','lnpreimage',preimage,hash] (and ['proof','deposit',...] for barter).
- useTradeReputation verifies and counts it in paymentVerified.
- Honest scope: proves PAYMENT, not delivery; money legs only - a pure hardware
swap has no invoice, stays attested; a deposit receipt gives barter real cost.
Newer nostr-tools removed nip57.getSatoshisAmountFromBolt11, breaking
useZaps and useCrewGoal. Add src/lib/bolt11.ts (getSatoshisFromBolt11)
that parses the sat amount straight from the invoice's human-readable
prefix — no external dependency, immune to nostr-tools API churn — and
use it in both hooks.
