Upgrades six PARTIAL modules to the gold-module standard (lesson/demonstration/
knowledge-check/guided-exercise/lab(s)/reflection), preserving every existing lab
activity_id and scenario_id: root-06-m03 (jobs/cronjobs/daemonsets), root-07-m04
(ingress/networkpolicy), root-07-m02 (configuration/secrets, converted in place
from a bare 5-lab bank), root-09-m02 (serviceaccounts/rbac), root-09-m03
(network/supply-chain security), root-10-m03 (troubleshooting framework).
root-05-m01 (20-task kubectl-fluency bank) gets a minimal bookending lesson +
reflection rather than a full redesign, since each task already carries its own
explanation. root-12-m01, root-capstone-m01, and root-09-m04 are promoted to
READY via documented exceptions (no new activities) where adding one would
misrepresent their intentional design.
Wires a new rootnode-security-assessment (exam, 60min, hint_policy disabled)
using the existing Phase 3B assessment engine: 3 required hands-on CORE
scenarios + 4 random-draw pools covering SecurityContext, RBAC, network
policy, and the 7 previously-unwired CKS MCQs. Wires the previously-unwired
readiness-probe-task scenario as an OPTIONAL practice lab in root-10-m01,
using the existing is_required model.
Adds root-11-m01-devops-platform-thinking — an honest, lesson-only ROOT 11
orientation module naming DevOps/platform engineering practices already
exercised in ROOT 05-10/12, explicit that GitOps/CI-CD/IaC/observability need
lab infrastructure this platform doesn't yet provide. No fake labs.
Adds infra/scripts/validate-course-content.js: cross-checks the DB against
scenario/content files for duplicate ids, orphans, invalid references, cycles,
sequence collisions, instructor-notes leakage, and (new) self-paced content
deferring explanation to a live instructor. 0 errors against the resulting
22 courses/modules, 163 activities, 98 scenario files.
No application code changed — every gap was satisfiable with existing tables
(course_modules, module_activities, assessment_definitions) and the existing
content-delivery pipeline.

Four new modules, moving ROOT 09 off PLANNED and building the
22-scenario CKS-style bank into a coherent course instead of
disconnected exam tasks — see docs/ROOT_CURRICULUM_COVERAGE_MATRIX.md
for the CORE/GUIDED/INDEPENDENT/ADVANCED/ASSESSMENT-BANK classification
behind every placement.
root-09-m01-security-model-and-securitycontext — READY, full
gold-standard pattern: defense in depth, least privilege, hardening a
Pod with SecurityContext. Lesson, demonstration (a Pod before/after
hardening), knowledge check, guided exercise (a hardening checklist),
real Labs (CORE: non-root/drop-capabilities/read-only-fs/
pod-security-context; GUIDED: seccomp; ADVANCED: AppArmor; INDEPENDENT:
the generic pod-security-context duplicate), and a reflection.
root-09-m02-serviceaccounts-and-rbac — PARTIAL: workload identity and
least-privilege permissions. Lesson + knowledge check + real Labs.
root-09-m03-network-and-supplychain-security — PARTIAL: NetworkPolicy
as a security control (default-deny), image/registry trust, TLS
ingress. Lesson + knowledge check + real Labs.
root-09-m04-cluster-hardening-and-runtime — PARTIAL, deliberately
survey-depth: Pod Security Admission and a lighter treatment of
audit-policy/runtime-sandboxing topics that don't belong in the core
daily-driver path.
