/**
 * Durable Mission Graph — integration transactions (2.0.0).
 *
 * An integration transaction coordinates cross-objective, cross-repository
 * confirmation of work. It is fully transactional:
 *   PREPARED → CHECKPOINTED → VALIDATING → CONFIRMED
 *   any stage → ROLLED_BACK
 *
 * Checkpoints precede mutation and capture per-objective state. A localized
 * rollback restores only the checkpoints captured within this transaction;
 * independent completed work outside the transaction is preserved.
