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.
