- 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.
