Function: acceptSplice()

acceptSplice(channel, proposal, leaseProvider): Promise<SpliceAcceptance>

Counterparty accepts a splice proposal by co-signing the splice TX digest.

Requires the channel to be in 'quiesced' state.

WOTS lease safety: reserves a key slot before signing. The returned acceptorReservationId and acceptorSigningIndices are embedded in the SpliceAcceptance and consumed by finalizeSplice to commit or burn the acceptor's key-slot reservation.

The acceptor independently:

  1. Validates party membership (proposer and acceptor both in channel).
  2. Validates proposal balance conservation and amount constraints.
  3. Cryptographically binds the signed draft to the proposal params by recomputing the expected draft from params + channel and comparing digests — rejects if they differ (tamper detection).
  4. Reserves a WOTS key slot via leaseProvider.wotsLease.
  5. Signs the splice TX digest with reserved indices.
