boot-labs.js drives the real admin Prepare-Labs endpoint (reusing the existing session-helper.js from Phase 3A) and records boot time/failure rate; sample-resources.sh samples real docker stats for running Labs. capacity-model.js turns measured per-Lab CPU/memory into a recommended/ warning/hard-admission-control concurrency threshold - no concurrency number is hardcoded as a marketing figure, every input is explicitly placeholder data until measured against the real host. Plus deploy/rollback/smoke-test scripts used by the CI/CD and deployment runbooks. All syntax-checked; validate-compose.sh and capacity-model.js actually run against real inputs.

// Load test tooling (Phase 4 §24) — provisions N concurrent Labs via the real admin
|
|
// Prepare-Labs endpoint (the same code path a real instructor's "Prepare Labs" click uses,
|
|
// platform/api/src/admin-routes.js), measures boot time and failure rate, and (if run ON the
|
|
// Lab Host, or given SSH access to it) samples per-Lab CPU/RAM/disk via `docker stats`.
|
|
//
|
|
// This produces REAL numbers against whatever stack it's pointed at — a local dev stack today,
|
|
// the real rn-lab-host-01 once it exists. It does NOT fabricate a concurrency number; the
|
|
// report is only as meaningful as the host it ran against (see the report template's WARNING
|
|
// banner when run against anything other than real target-class hardware).
