New docs/PHASE3B_LEARNING_AND_ASSESSMENT.md covers the attempt/learning-record model,
progressive hints (including the Gateway response-rewrite mechanism), curriculum completion
rules, the assessment/exam engine and its timer/draw integrity guarantees, the RootNode
Capstone design, achievement records, the deliberately minimal versioning model, instructor
analytics, the Phase 3B RBAC matrix, security/integrity assumptions, dev/test commands, known
limitations, and the Phase 4 boundary.
Updates ENGINEERING_SOP.md (roadmap items 2/7/8 now done, new section 12, corrects a stale
capstone-placeholder description in section 4), LAB_ARCHITECTURE.md's status line,
README.md (corrects the 'Lab image unmodified' claim now that its frontend bundle carries
Phase 3B UX, plus new platform properties), platform/README.md, and platform/api/README.md.
New docs/PHASE3A_IDENTITY_AND_INSTRUCTOR_ACCESS.md covers the schema, persistent session
design, instructor accounts, the full RBAC matrix, cohort scoping (including the documented
raw-environment-id simplification), student session hardening (explicitly still
classroom/pilot identification, not production auth), CSRF, rate limiting, audit logging,
the API inventory, a security hardening checklist, test results, known limitations, the
future OIDC path, and production HTTPS/cookie expectations — with an explicit BUILT NOW vs.
FUTURE split.
Updates ENGINEERING_SOP.md (new §9/§10, closing a stale '(§9)' forward-reference that dated
back to Phase 2B), LAB_ARCHITECTURE.md status line, README.md, platform/README.md, and
platform/api/README.md (bootstrap-owner usage, new config vars, no more ADMIN_PASSWORD).
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.
