/**
 * LH-3 Mission Continuation Scheduler v1.
 *
 * Freezes the exact continuation identity, cycle bindings, revision
 * guards, and event digests for a single Mission Execution. The
 * scheduler is a deterministic, replayable event log that can be
 * independently verified without the caller runtime.
 *
 * Every mutation produces a single immutable ContinuationSchedulerEvent
 * with a SHA-256 digest computed over its ordered fields. Events form
 * a hash chain via previousEventDigest. The aggregate history digest
 * covers the full event sequence.
 *
 * Threat Model:
 *   The unkeyed event hash chain and semantic replay protect against
 *   accidental mutation, partial rewriting, internally inconsistent
 *   rewriting, broken ordering, and broken replay. They do not claim
 *   protection against a privileged writer capable of rewriting the
 *   complete record and all digests consistently.
