/**
 * Lifecycle hooks. Decorated instance methods run on the hydrated entity around
 * entity-based writes (`insert*`, `save`). They run in declaration order, are
 * awaited sequentially, and a throw aborts the write.
 *
 * Before-hooks may mutate the entity and run **before** validation and before
 * the document is prepared for the driver. Filter-based bulk paths
 * (`updateMany`, `updateOne`, `bulkWrite`, `bulkUpsert`) do **not** run
 * per-entity hooks.
