New platform/api/ service owns students, cohorts, curriculum, progress, scenario attempts, and student/admin sessions. No k3s, no --privileged, no terminal runtime — starts instantly, unlike the old identity service which booted an unused k3s cluster just to serve roster/progress APIs. Provisioner calls (student and admin) are consolidated here too, in provisioner-client.js, so it's the only service that talks to the Provisioner directly.

// Postgres connection + migration runner — same pattern as platform/provisioner/src/db.js
|
|
// (check-before-alter idempotency, tracked in schema_migrations). Same database
|
|
// (rootnode_platform) as the Provisioner, different table set: this service owns
|
|
// students/cohorts/enrollments/curriculum_assignments/progress/scenario_attempts/
|
|
// exam_sessions; the Provisioner owns lab_hosts/environments/environment_events. Both connect
|
|
// to the same Postgres instance — scenario_attempts.environment_id is a real FK across that
|
|
// shared boundary, which Postgres allows regardless of which service's migrations created
|
|
// which table.
