DATE_COLUMN_OVERRIDES =

Per-table date column overrides. The Retention module defaults to :created_at, but legacy tables (like tasks) use :created. Migration 051 may add a created_at column/alias for tasks (implementation varies by adapter); this map forces use of :created so behavior is consistent across legacy schemas and adapters.
