COURSE_AUTHORING_STANDARD.md — the standard every future lesson/module
must follow (target learner, prerequisites, measurable objectives,
concept-before-lab, instructor notes, terminology, versioning, review
requirements), grounded in the gold-standard module as the reference
implementation.
PHASE6A_ROOT_COURSE_FOUNDATION.md — the phase summary: youth-ladder
context, the Google Workspace status already recorded in Phase 5C's own
docs, architecture/build summary, honest content states, test results,
explicit non-goals, and known limitations/Phase 6B recommendations.
Updated ENGINEERING_SOP.md (new Phase 6A section + a curriculum-content
cross-reference), REMOTE_AND_SELF_PACED_ARCHITECTURE.md (a 7th
closed gap: self-paced enrollment now resolves to a real course tree,
not just a scenario list), LAB_ARCHITECTURE.md (Phase 6A reuses the
disposable Lab unmodified, verified by a real rehearsal), and
platform/README.md (course model in the api/ summary, new e2e suite
descriptions for 5A/5B/5C/6A which were missing entirely, and the
real-Lab rehearsal script).

- PHASE5B_SELF_PACED_ENROLLMENT.md: the full design doc.
- RUNBOOK_SELF_PACED_ENROLLMENT.md: operational runbook for /admin -> Programs.
- WEBSITE_ENROLLMENT_INTEGRATION.md: the complete contract for the separate website team —
endpoint, auth, request/response schema, idempotency/retry rules, student matching, minor/
no-email behavior, error responses, what not to send, local testing, production-secret
handling. Written to be usable without reading the Platform API source.
- REMOTE_AND_SELF_PACED_ARCHITECTURE.md: closes the self-registration/curriculum-assignment/
delivery-mode/enrollment-model gaps this doc previously flagged as Phase 5+ scope.
- ENGINEERING_SOP.md: new §15. LAB_ARCHITECTURE.md, PRODUCTION_VALIDATION_CHECKLIST.md,
README.md, platform/README.md: cross-references and a Phase 5B production-validation section.
- PHASE5A_STUDENT_IDENTITY_REMOTE_CLASSROOM.md: the full design doc.
- RUNBOOK_STUDENT_ACCOUNT_LIFECYCLE.md, RUNBOOK_REMOTE_CLASSROOM.md: operational runbooks.
- REMOTE_AND_SELF_PACED_ARCHITECTURE.md: closes the 'no real student authentication' gap this
doc previously flagged as the one item blocking self-paced delivery.
- ENGINEERING_SOP.md §5 rewritten (was describing a pre-Phase-2A state no longer true of any
deployed version of this codebase) plus a new §14; roadmap item 3 updated.
- LAB_ARCHITECTURE.md, PRODUCTION_VALIDATION_CHECKLIST.md, README.md, platform/README.md:
cross-references and a Phase 5A production-validation section.
Master overview (PHASE4_1_PREPRODUCTION_HARDENING.md) covering all 27
substantive items, plus REMOTE_AND_SELF_PACED_ARCHITECTURE.md (reviews
what already works for remote/self-paced delivery - student-driven
provisioning, cohort-less students, idle-reaper-destroy-then-continue -
and the one real gap: student authentication, explicitly Phase 5 scope,
not built here).
Updated PRODUCTION_NETWORK_SECURITY.md (the Gateway-to-Lab gap is now
RESOLVED, with the full design writeup and a new control-plane-vs-data-plane
section), PRODUCTION_DEPLOYMENT.md (four-cert TLS bundle),
PRODUCTION_VALIDATION_CHECKLIST.md (Router mTLS check, admission control
checks), PHASE4_PRODUCTION_INFRASTRUCTURE.md and ENGINEERING_SOP.md and
LAB_ARCHITECTURE.md (stale 'known gap' pointers updated to point at the
resolution), BACKUP_DR.md (destructive drill), README.md and
platform/README.md (Phase 4.1 pointers, lab-router component, updated
known-limitations).
Also fixes a real pre-existing bug found while auditing what gets
committed: infra/.gitignore's patterns were written repo-root-relative
(e.g. "infra/terraform/...") but the file lives in infra/, so git resolved
them relative to THAT directory and none of them ever matched anything -
a real .terraform/ provider cache showed up as untracked when it should
have been ignored. Fixed by dropping the redundant leading "infra/" from
every pattern.
Status: PHASE 4.1 COMPLETE / PRE-PRODUCTION HARDENING COMPLETE / READY FOR
HARDWARE DEPLOYMENT.
Master overview (PHASE4_PRODUCTION_INFRASTRUCTURE.md) plus five detail docs
(PRODUCTION_DEPLOYMENT, PRODUCTION_NETWORK_SECURITY, BACKUP_DR,
OBSERVABILITY, CAPACITY_PLANNING), a master PRODUCTION_VALIDATION_CHECKLIST,
and 12 runbooks (first deployment, normal deploy, rollback, Postgres
restore, VM rebuild for both hosts, Docker TLS rotation, TLS renewal, owner
recovery, stuck Lab cleanup, failed migration, backup failure, disk
failure, Lab Host resource pressure).
PRODUCTION_NETWORK_SECURITY.md prominently documents the one genuine
architectural gap this phase surfaced: the Gateway's existing
env.internal_ip mechanism for reaching a Lab container assumes Gateway and
Lab share a Docker daemon, which breaks once Labs run on a genuinely
separate rn-lab-host-01 VM. The network-policy half is built (a firewall
allowance for Gateway->Lab-Host on a published port range); the
application half (Provisioner/Gateway address handling) is an explicit,
reviewed, NOT-YET-BUILT follow-up flagged there rather than silently
decided.
Updated LAB_ARCHITECTURE.md, ENGINEERING_SOP.md, README.md, and
platform/README.md with Phase 4 pointers, consistent with how every prior
phase updated these.
Status: PHASE 4 BUILD COMPLETE / PRODUCTION DEPLOYMENT PENDING HARDWARE.
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 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.
