RP-02 - Retention Authority

Status: RESOLVED_BLOCKING

Codex selected T1 option i. Retention remains inside counted authority surface storage_class_manifest #05:

• retention_interval_seconds
• partition_capacity_rows
• archive_required
• archive_storage_class_id

Every high-volume runtime-evidence row binds storage_class_item_id. Generic partition/archive engines read only the ACTIVE sealed storage-class row. Seal rejects an archive-required row with no valid immutable-versioned archive target. No numeric policy literal or separate retention table exists.

The storage-class item hash flows through its manifest payload into H01/H02. Retention change is a new sealed version with quorum/epoch/evidence. Exactly 27 authority surfaces remain.
