/**
 * Participant operation keys drifted between building the Bitcoin artifacts
 * and the vault freezing its epochs.
 *
 * A *sibling* of `RegisteredVaultVersionMismatchError`, never a subclass, and
 * the distinction is load-bearing. On a version mismatch the orchestrator drops
 * the local pending-pegin record, because the on-chain `prePeginTxHash` is
 * still the authoritative copy of the transaction and a later resume can safely
 * broadcast it from the indexer.
 *
 * Key drift breaks exactly that assumption. The registered hash commits to a
 * transaction whose scripts embed the *pre-rotation* keys, while the vault
 * froze the *post-rotation* epoch — so every counterparty resolves a different
 * funding output and the deposit can never activate. Dropping the record would
 * discard `buildParticipantOperationKeys`, the only thing that lets the resume
 * path re-detect the drift; the next attempt would fall back to the indexer's
 * copy, pass the hash check, and broadcast the very transaction this refused,
 * locking BTC until the refund timelock.
 *
 * So: callers must keep the pending record when they catch this.
