// Phase 6C §22 — the curriculum-completion dress rehearsal. One continuous realistic student
// narrative through a module Phase 6C actually upgraded this phase (ROOT 07's Configuration &
// Secrets, converted in place from a bare 5-lab bank to a full gold-pattern module), using a
// REAL k3s Lab end to end: login -> program -> course -> lesson -> demonstration -> knowledge
// check -> guided exercise -> real Lab -> real kubectl -> validation -> progress persistence,
// then an instructor narrative confirming the resulting learning state is visible. Same
// conventions as test-phase6b-root-course-rehearsal.js: assert-based, no framework, real k3s
// boots, no mocking.
//
// Run via run-phase6c-security-config-rehearsal.sh, which brings up
// platform/docker-compose.dev.yml first.
