New Phase 1 Platform database — PostgreSQL, separate from the Lab image's own SQLite (which keeps its current students/progress data untouched, decision #2 / correction C in docs/LAB_ARCHITECTURE.md). Schema (platform/provisioner/migrations/): - lab_hosts: the abstraction that keeps Docker connectivity out of code — endpoint (unix:// or tcp://+TLS), enabled flag. Phase 1 ships one row. - environments: environment_id (UUID), student_id (opaque external identifier, no FK — students table isn't in this database yet), lab_host_id (real FK), status, routing_token (CSPRNG via crypto.randomBytes, opaque), container/ network identity, resource limits, lifecycle timestamps. - environment_events: append-only audit trail, one row per lifecycle transition, never logs the routing token in plaintext (see lifecycle.js's redact()). File-based migration runner (db.js) matching the check-before-alter idempotency pattern already used in the Lab image's backend/server.js, applied on every Provisioner boot. Resource limits and the lab_hosts seed are config files (config/resource-policy.yaml, config/lab-hosts.seed.yaml), not database tables — there's no admin UI to manage them via a database yet, so a DB-backed policy table would just be a write path nothing uses.
