"""Bootstrap seed data applied by the initial migration.

The :data:`RETENTION_CLASS_SEEDS` entries match the five v1 retention classes
listed in ``docs/ARCHITECTURE-BLUEPRINT.md``. Default durations are intended
to be overridable by an operator configuration file (WP-0003); the seed
values only ensure the registry has sensible defaults on a fresh DB.
