 * Folds a `batch` declaration into the escalation's storage shape:
 * queryable facets in `metadata` (`batch_pending`, `batch_count`,
 * `batch_keys`) and the payload accumulator in `envelope`
 * (`batch_items: {}`). `partialOnTimeout` is stored beside the items so
 * the expiry statement delivers the filled items instead of `false`. Pure
 * and deterministic — safe on the replayed `condition()` path. Throws
 * synchronously on an invalid declaration so a bad batch never reaches a
 * durable write.
