Hybrid Architecture
WordPress/MySQL stores settings, license data, tenant registry, tenant users, domains, CPT registry, and migration records. SQLite stores tenant application data.
SQLite Files
Tenant database files are named by UUID and sharded under the first two UUID characters. Connections use PDO, WAL mode, foreign keys, and busy timeout.
