The application deploys as the project-brain Compose project under its own Hostinger root. PostgreSQL, API, and worker have distinct roles; API and worker share only the artifact mount they require. Migrations run before worker processing, a repair made during Phase 4 qualification.
Deploy one revision at a time. Record image/configuration/migration state, check health, run the affected acceptance harness, and preserve durable sentinels. Never use broad volume deletion or host-wide cleanup. Basic Memory is a distinct project-brain-dev-memory project and must not be touched by application deployment.
