DB Purger deletes (or soft-deletes) every row related to a single top-level record (e.g. a company or account) using a declarative Ruby purge plan. Tables are purged in primary-key batches, child tables before their parents, with plan validation against the live schema, an explain (dry-run) mode that emits SQL, and ActiveSupport::Notifications instrumentation for metrics.
