-- Async sort jobs: lifecycle + result for collection expansion + cold drains.
-- Created 2026-05-01 (Spec B+F).
-- Depends on: 01_schema.sql (touch_updated_at() function, pgcrypto extension).
-- Docker initdb runs files alphabetically, so 01_ executes first; for live
-- one-shot psql application against an existing DB, both prerequisites
-- already exist.
