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.
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.
