A flow that carves and then waits minutes on a settlement poll used to
commit the carve only after the whole flow resolved - an abort mid-wait
left burned inputs spendable locally and stranded the fresh outputs.
ensureExactAmount now reports a mutation-bearing carve through the new
FundOperationOptions.onCarve checkpoint the moment its outcome is known;
payWithBearers and transferBetweenMints thread it through.
Because the carve may now be committed before the flows' classification
rotates run, those rotations no longer rewrite carve.note in the result -
returned funds come back as a separate verified rotatedNote, so the
committed carve and the re-secured note can both be persisted. NWC's
payChangeset adapts to the rotatedNote field; its own commit timing is
unchanged (follow-up).
Review feedback: bind the claim answer to the secret that was polled
before building a note from it. The kit already guarantees this -
claimMintedNote returns the queried secret by construction and
fetchNoteInfo rejects a mismatched k1 echo - so the assert cannot trip
through the kit (and is therefore not separately testable); it exists so
a future kit regression fails loudly instead of tracking a wrong secret.
A named target needs no verify URL: the note appearing at the wallet's own
secret is the settlement proof, and it is claimed without a rotate. The
claim material carries the secret - and the unverified note at it - from
the start, so a melt settling after the poll budget is never a lost note;
the source-note oracle classification is unchanged.
