/**
 * The replay pin of a checkpoint (journal spec §2.11 §7; NEW-9, R5-8,
 * T12797): what an endorsing device must replay under to recompute the
 * checkpoint's tallies.
 *
 * - `journal`: sha256 over the store's WHOLE ordered migration journal,
 *   `(created_at, name, hash)` per applied migration, in drizzle's order
 *   `(created_at, name)`. A single head is not enough: stamped and drifted
 *   stores differ below it.
 * - `triggerSetHash`: sha256 over the normalized DDL of the store's OWNED
 *   triggers ({@link OWNED_TRIGGERS}: the guard and side-effect triggers a
 *   replay runs under), sorted by name. Device-local maintenance triggers
 *   (the twin-collapse docs freeze, whose message names the build that froze
 *   that store, and the legacy track triggers) never touch a replayed table,
 *   so they stay out: two devices with the same replay semantics agree
 *   (T13298). Normalization is literal-safe ({@link normalizeTriggerDdl}).
 * - `transitions`: the schema rise points inside the checkpoint's window;
 *   the caller computes them from the segments it replayed (empty for a
 *   genesis checkpoint, which has no window to replay).
 *
 * The server cannot check the two hashes; another device recomputes them
 * from its own store and requires a match before it endorses.
 *
 * @task T12343
