/** A recall fence, not the store's transaction counter. No payloads are retained.
 * Collection bookkeeping and delivery polls cannot change searchable memory.
 * Commit/extraction transitions can, including reconciliation after a lost reply.
 * Governance jobs are retained after completion, so a full edit during a slow
 * recall still changes the fence even when no barrier remains pending.
 * This opaque token is NOT permission to recall: callers must separately reject
 * disabled/retired state and pending governance in their host-bound scope before
 * reading and before returning. Also retain owner/isolation, model and abort guards.
 * Compare tokens only within a request; do not persist them across plugin versions.
