CourseView.jsx — My Programs -> ROOT_ -> Course -> Module -> Activity ->
Launch Lab -> back -> continue, nested inside the existing self-paced
ProgramsTab rather than a second portal. Renders lesson/demonstration/
knowledge-check/guided-exercise/reflection content via the existing
react-markdown+remark-gfm stack (already used by ScenarioPanel.jsx — no
new dependency). Locked modules/courses are inert, not hidden — the
server is still the actual gate (course-routes.js).
ProgramsTab.jsx gains a 'View Courses' button alongside the existing
'Continue Learning' button — the original direct-to-Lab flow is
byte-for-byte unchanged; both paths call the identical launch sequence
underneath.

- notification-routes.js: global list (owner/admin only), per-student list (scoped via
requireStudentRelationshipAccess), resend-activation (mechanically the same as
regenerate — Phase 5A's token model already guarantees only the latest is ever valid, so one
action covers both), a dev-only preview route (unconditionally refuses when
COOKIE_SECURE=1, mirroring student-auth-routes.js's existing dev_reset_token gate).
- NotificationsView.jsx: owner/admin global notification list, paginated, matching
AuditView.jsx's exact convention.
- StudentsView.jsx: student detail gained a Resend activation control and a Notifications
history card; Credentials card now explains the automatic-email behavior.
- AdminPortal.jsx: new Notifications nav entry (owner/admin only).
- ProgramsTab.jsx: Active/Completed programs, real progress, deterministic Continue Learning
(reuses the same launch/poll pattern MyLearningTab already established), entitlement-blocked
states shown with a real reason, never a silent dead end.
- StudentDashboard.jsx: new My Programs tab. api.js: programs/program/launchProgram.
- StudentsView: credential status in the roster table, a create-student form
(email/login-ID/cohort), convert/reset-password/revoke-sessions controls per student, a
bulk CSV import form. Every one-time activation/reset link is surfaced exactly once, never
re-fetchable.
- ClassroomView: cohort picker -> schedule/list classes -> a live dashboard (participants with
presence/Lab-status/current-work, help queue with acknowledge/resolve, current-activity
setter, announcement poster, start/end/cancel, Prepare Labs). Polls the dashboard endpoint
rather than a second push channel.
- AdminPortal: new Classroom nav entry. CohortsView's existing quick-add-student call updated
for createStudent's new object-argument signature.
- LoginScreen (credentialed, now the default entry point) with links to legacy pilot entry
and forgot-password; SetPasswordScreen (shared activate/reset UI, driven by
?activate=/?reset= query params — no router library, matching this app's existing
state-machine-per-shell convention); ForgotPasswordScreen (anti-enumeration, dev-only
reset-token surface).
- ClassroomTab: LIVE NOW banner, join, heartbeat only while joined and the tab is mounted,
guidance-only current-activity link, own Lab status/launch (reuses the My Learning tab's
exact API), announcements, Need Help form. No chat, no video, no shell access.
- ProfileTab: identity, cohort, progress, achievements, active-session count,
change-password (gated on has_credentials).
- PlatformShell rewritten as an explicit view state machine; StudentDashboard gained the new
tabs; api.js/Platform.module.css extended to match.
- Real server-side pagination (platform/api/src/pagination.js) on the audit
log (was a flat LIMIT 200), student attempt history (was LIMIT 100), and
assessment session history (was fully unbounded - the one genuine growth
risk found). Frontend updated (AuditView, AssessmentsView, StudentsView).
- Admission control: resource-policy.yaml's new (disabled-by-default)
admission_control.max_concurrent_labs, checked before touching Docker at
all, returns a clean 503 CAPACITY_EXCEEDED instead of failing mid-provision.
Relayed as a clean student-facing message, never a raw 500. New
GET /capacity endpoint feeds the instructor dashboard.
- cohort_instructors.role_in_cohort (existed since Phase 2B, never read) is
now enforced: teacher vs viewer, rbac.js's
requireCohortWriteAccess/requireStudentCohortWriteAccess.
- GET /api/version - app version, deployed Git SHA, latest migration as a
schema-version stand-in.
- Structured assessment authoring UI (AssessmentsView.jsx's PoolSpecEditor)
replaces the raw-JSON pool_spec textarea, backed by a new
GET /api/admin/scenario-catalog endpoint. Owner-only raw-JSON fallback
remains for anything the structured editor doesn't cover.
- NEEDS_ATTENTION_FAIL_THRESHOLD/STALE_DAYS moved to env-var configuration.
Full regression suite (e2e-phase2a/2b/3a/3b, 67/67) re-run clean after
these changes; frontend production build confirmed clean.
StudentDashboard is now tabbed: My Learning (the original Phase 2A/2B flow, extracted
unchanged into MyLearningTab and extended with an overall percent-complete bar), Practice,
Assessments (available/active-with-live-countdown/history), Capstone (locked checklist ->
unlocked -> start/resume -> completed), Achievements (a flat dated list, not a leaderboard).
Inside the Lab UI: ProgressiveHints replaces the static hint array render when the Gateway has
stripped hints (detected via scenario.hints being undefined but hint_count present - standalone
dev mode never sees this, so it keeps the original behavior); a new top-level AssessmentBanner
shows a live countdown and completion count whenever a Platform assessment is running,
rendered alongside (not replacing) the pre-existing Lab-local exam-mode UI, which is untouched.
New /api/admin routes: cohort learning summary (completion by stage, active learners),
per-student learning detail (attempts, hint usage, assessment history, capstone state),
scenario analytics (completion rate, avg attempts, failure/hint frequency, avg time), and a
needs-attention view (repeated failures, hints used but still stuck, inactivity, an expired
assessment - deliberately instructional wording, not punitive, with an explicit test asserting
that). Assessment definition CRUD (admin/owner only), cohort assignment and session view/cancel
(any instructor role, cohort-scoped for a plain instructor via the existing Phase 3A RBAC
helpers - no new authorization primitives needed).
New Learning and Assessments tabs in the admin portal, visible to every instructor role;
definition-authoring controls are shown but the server 403s a create/edit from a non-admin/
owner role, same pattern CohortsView already uses for admin-only controls.
Login form is now email+password (was a bare shared password field). Nav conditionally
shows Instructors (owner only) and Audit (owner/admin) tabs based on the signed-in
instructor's role. New InstructorsView (create/list/edit accounts, role/status controls,
session list + revoke-all, password reset — owner only), AuditView (read-only audit event
table), AccountView (change-password form for the signed-in instructor). CohortsView hides
the create-cohort form and curriculum-assignment button for the 'instructor' role — the
server already enforces this; this just avoids showing controls that would 403.
Non-HttpOnly rn_csrf_s/rn_csrf_i cookies, set on login, echoed back as X-CSRF-Token on every
state-changing request — defense in depth on top of (not instead of) SameSite=Lax. In-memory
sliding-window rate limiting on instructor login (8 attempts / 5 min per ip:email, no new
dependency).
Real bug found while wiring this up: the Gateway's own progress-relay call (triggered when a
student solves a scenario) is a server-to-server POST to /api/progress/record relaying the
browser's session — it needs to forward the CSRF token too, and needs to forward BOTH the
rn_csrf_s cookie and a matching X-CSRF-Token header (forwarding only the header still 403'd,
since the double-submit check needs both on the request Platform API actually receives).
Also tightens the Gateway's session-resolution cache from 5000ms to 2000ms, so a
revoked/expired session stops working at the Gateway within a tighter, tested bound.
Frontend (admin + student API clients) now reads the relevant rn_csrf_* cookie via
document.cookie and attaches it on every POST/PATCH/DELETE.
New /admin route (frontend/src/admin/), gated by a separate admin
session (scrypt + timingSafeEqual against ADMIN_PASSWORD, no plaintext
storage, no new dependency). Covers cohort CRUD + roster + curriculum
assignment, and student CRUD + cohort assignment + environment/progress/
attempt views, all under /api/admin/* on the Platform API.
main.jsx now does a three-way path split (lab / admin / platform) so the
existing, unmodified Lab UI, the student dashboard, and the new admin
portal all ship in one Vite bundle without a router dependency.
Replaces the Phase 2A pilot ?sid= query param with an HttpOnly,
SameSite=Lax session cookie. Gateway now derives student identity from
the session (via Platform API's /api/session/whoami) instead of trusting
a client-suppliable id, and checks ownership on every proxied HTTP and
WebSocket Lab request, not just the initial navigation.
Fixes a routing bug found during testing: the fallback route was using
'does this session own a running environment' to decide whether an
unprefixed /api/* call belonged to the Lab UI or the dashboard — true in
both places. Replaced with an explicit LAB_OWNED_PATHS allowlist of the
exact unprefixed paths the existing Lab UI actually calls.
e2e-phase2a.js rewritten to use a cookie jar instead of headers/query
params, with explicit impersonation-rejection tests added. 10/10 passing.
StudentDashboard.jsx — "Up Next" curriculum view + Launch Lab flow, in one
component since they share state (environment status affects what curriculum
actions make sense).
- Renders GET /api/curriculum/path as-is: the existing RootNode path
(Foundation -> Workloads -> Networking -> Configuration -> Troubleshooting
-> Real Ops -> Capstone), no new structure invented. Capstone stays the
locked placeholder from the earlier slice.
- Launch Lab -> POST /api/environment/launch, polls status every 2.5s while
provisioning/resetting, transitions through none -> provisioning -> running
-> error with a distinct UI state for each (EnvironmentPanel). On running,
navigates to launch_path with the student's own id as ?sid= — a
defense-in-depth ownership check the Gateway verifies on that specific
navigation (see the gateway commit).
- One "Recreate Lab" control, calling POST /api/environment/reset — no raw
destroy-without-recreate exposed to students, matching "don't expose raw
destroy/admin controls beyond what is safe for a student." A visible note
states progress is saved separately and survives.
Platform.module.css reuses the existing design tokens from index.css
(--green, --surface, --text, etc.) so this reads as the same product as the
Lab UI, not a bolted-on separate app.

New Platform Shell entry point (frontend/src/platform/) alongside the
existing, completely unmodified Lab UI (App.jsx and everything under
frontend/src/components/). main.jsx now splits on the current URL path —
/lab/<token>/ renders the existing <App/> exactly as before; anything else
renders the new <PlatformShell/>. Both live in the same built bundle (it's
served both by the persistent identity instance and by every ephemeral Lab
container), split purely at runtime.
- EntryScreen.jsx — cohort dropdown -> name dropdown (existing
GET /api/roster/cohorts, GET /api/roster?cohort=) -> POST /api/login. No
password. Visibly labeled pilot identity, not production auth, per the
governing requirement that this be stated explicitly, not just true in the
architecture docs.
- api.js — student_id lives in localStorage only, sent as X-Student-Id on
every authenticated request. Every authenticated call throws if no student
is stored rather than silently going out anonymously — this is what
"prevent accidental anonymous progress writes" means in practice, not just
a comment.
- PlatformShell.jsx — entry screen if no stored session, dashboard otherwise.

Pre-Phase-1 platform work, approved and tested earlier but not yet committed:
- Terminal banner: "RootNode Academy Lab — node: k8s-lab", upstream KubeKosh
attribution left untouched in footer/README/LICENSE.
- RootNode curriculum mode: scenarios/rootnode-path.json (Foundation -> Workloads
-> Networking -> Configuration -> Troubleshooting -> Real Ops -> Capstone),
built from existing scenario content grouped by category, no new scenarios
invented. New GET /api/curriculum/path endpoint.
- Student roster + per-student progress: instructor-roster, pick-your-name login
(no password), students/environments-adjacent progress table migrated to a
(student_id, scenario_id) composite key so practice progress and exam sessions
are isolated per student instead of one global bucket. New /api/roster,
/api/login endpoints.
- scenarios/data/*.json: added isolation_type metadata (shared_namespace vs
ephemeral_cluster) from an audit of which scenarios execute cluster-scoped or
node-level commands. This was Tier-1-isolation groundwork that got superseded
same-day by the full-ephemeral-per-student architecture (see
docs/LAB_ARCHITECTURE.md) — the field is kept as descriptive metadata only,
per the note now in scenarios/SCHEMA.md. Not wasted: it's an accurate audit of
which scenarios touch cluster-scoped resources, useful independent of isolation
model.
- .gitignore added (node_modules/, frontend/dist/, *.db, /data/, .env) — none
existed before; without it, npm installs during testing would have landed in
a commit.
Known limitation still open: no frontend UI for any of this yet (login screen,
roster-add form, curriculum view) — API-only. No auth on the roster-add endpoint.
