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.
Was ambiguous — backend/frontend committed lockfiles, api/gateway/provisioner didn't, with
no stated reason either way. Now explicit: every first-party Node service commits its
package-lock.json, validated with npm ci before each commit that touches it.
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 docs/PHASE2B_ADMIN_AND_PLATFORM_DATA.md covers the Platform API
split, Postgres schema and migration guarantees/rollback, the session
cookie architecture (including the whoami-routing-bug fix), the admin
portal, the API/security boundary, known limitations, and Phase 3+
future work.
Updates ENGINEERING_SOP.md §8, LAB_ARCHITECTURE.md, README.md, and
platform/README.md to reflect Platform API as the sole Provisioner
caller and Postgres as authoritative for identity/progress as of
Phase 2B.
- docs/PHASE2A_GATEWAY_AND_STUDENT_FLOW.md — the full Phase 2A record: node-pty
root cause and fix, Gateway architecture, student flow (entry through
reset/recreate), API routes added, HTTP/WebSocket routing design (and why
the lab-session cookie exists), security model (what's checked, and the
explicit statement that this is pilot identity, not production auth),
reset/recreate and reaper-recovery semantics, and known limitations found
during implementation (the identity instance's k3s resource cost and its
network_mode: bridge requirement, the Gateway's in-memory cache scope, the
?sid= check's coverage). BUILT NOW vs. FUTURE (Phase 2B) called out
explicitly per the governing requirement.
- docs/LAB_ARCHITECTURE.md, docs/ENGINEERING_SOP.md — status updated to
reflect Phase 2A is implemented and tested, not just Phase 1; roadmap item 5
updated accordingly; ENGINEERING_SOP's Provisioner section corrected (it's
no longer un-fronted — the Gateway is the only caller now).
- README.md — Multi-Student Deployment section updated to describe the
Gateway and student flow, not just the Provisioner; clarifies the
node-pty fix is the only change to the Lab image itself.

- docs/LAB_ARCHITECTURE.md — the full ephemeral-per-student design: two-VM
production topology (Platform VM / Lab Host VM, correction A), lifecycle,
data model, networking/egress model (correction B), resource model,
routing/auth model, security boundaries, failure/recovery behavior,
migration path from the current single container, and the lab-host
abstraction (correction D). Status updated to reflect Phase 1 is now
implemented, pointing at the two docs below for specifics.
- docs/PHASE1_PLATFORM_FOUNDATION.md — the Phase 1 build plan: exact Postgres
schema, service boundaries, API routes, lifecycle state machine, Docker/
firewall commands, security assumptions, file layout, and a 12-test plan.
Updated with "Implementation notes" at the points where testing surfaced
real deviations from the original design: the per-network (not static)
egress-proxy address resolution, the COALESCE reaper fix, and the
provisioning-failure cleanup fix.
- docs/ENGINEERING_SOP.md — new §8 mapping the platform/provisioner/ and
platform/egress-proxy/ components, what's built vs. not (no Gateway, no
frontend wiring — internal API only), and where identity still lives
(unchanged: Lab image's own SQLite). Roadmap item 5 (per-student isolation)
updated from "not started" to "Phase 1 done, not yet cleared for minors."
- README.md — Multi-Student Deployment section rewritten: the old per-student-
volume persistence model is superseded by the Platform's registry (progress
already lives outside the disposable container as of the prior curriculum/
roster work); points at docs/LAB_ARCHITECTURE.md and platform/provisioner/
for the real architecture instead of describing three delivery modes that
were never actually built out.
