Internal-only service (platform/provisioner/) implementing the environment
lifecycle from docs/PHASE1_PLATFORM_FOUNDATION.md: provision -> running ->
(reset -> running | destroy -> destroyed), plus experimental suspend/resume
(decision #3 — never on the guaranteed path, never relied on for correctness).
- src/docker.js — the lab-host abstraction (correction D). Resolves a
lab_hosts row into a connected dockerode client, unix:// socket or tcp://
with TLS client-cert auth. Refuses to connect to a tcp:// endpoint with no
TLS material configured rather than connecting unauthenticated. Validated
against both a local socket and a real remote Docker-in-Docker TLS endpoint
during testing — same code path either way, only the lab_hosts config
differs, which is the entire point.
- src/lifecycle.js — provision/destroy/reset/suspend/resume orchestration,
wired to docker.js + egress.js + the Postgres registry. Every Lab container
is privileged (required for k3s, not avoidable), gets its own Docker network,
no published host ports, deterministic naming (rootnode-lab-<short-id> /
rootnode-lab-net-<short-id>), and a CSPRNG routing token. Includes
reconcileOnStartup(), implementing the "don't trust stale state after a
crash/restart" requirement from docs/LAB_ARCHITECTURE.md §8 — verified by
killing a container out-of-band and confirming a Provisioner restart flags
the mismatch instead of trusting the stale 'running' row.
Found and fixed during testing: a provisioning failure (e.g. readiness
timeout) left an orphaned container/network/firewall chain behind with only
the DB row marked 'error'. provisionEnvironment's catch block now does
best-effort teardown of whatever was already created before marking the row
error — confirmed by deliberately failing a provision and checking no
container/network/chain survived it.
- src/server.js — the internal HTTP API (X-Provisioner-Key shared-secret auth
on every route, matching the instructor-passcode pattern already used for
the roster endpoint). Input validation on student_id/environment_id,
structured JSON errors with a request id, routing tokens redacted from every
response.
- docker-compose.dev.yml — Postgres + egress-proxy + provisioner on one
machine (the documented Phase 1 dev exception). provisioner and egress-proxy
run with network_mode: host + NET_ADMIN/NET_RAW, which is what lets
src/egress.js manipulate the host's DOCKER-USER chain without needing
interactive host sudo.

New Phase 1 Platform database — PostgreSQL, separate from the Lab image's own
SQLite (which keeps its current students/progress data untouched, decision #2 /
correction C in docs/LAB_ARCHITECTURE.md).
Schema (platform/provisioner/migrations/):
- lab_hosts: the abstraction that keeps Docker connectivity out of code —
endpoint (unix:// or tcp://+TLS), enabled flag. Phase 1 ships one row.
- environments: environment_id (UUID), student_id (opaque external identifier,
no FK — students table isn't in this database yet), lab_host_id (real FK),
status, routing_token (CSPRNG via crypto.randomBytes, opaque), container/
network identity, resource limits, lifecycle timestamps.
- environment_events: append-only audit trail, one row per lifecycle
transition, never logs the routing token in plaintext (see
lifecycle.js's redact()).
File-based migration runner (db.js) matching the check-before-alter idempotency
pattern already used in the Lab image's backend/server.js, applied on every
Provisioner boot.
Resource limits and the lab_hosts seed are config files
(config/resource-policy.yaml, config/lab-hosts.seed.yaml), not database tables —
there's no admin UI to manage them via a database yet, so a DB-backed policy
table would just be a write path nothing uses.

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.

- Split `scenarios/scenarios.json` into individual JSON files under `scenarios/data/` named `<scenario-id>.json`
- Split `scenarios/bundles.json` into individual JSON files under `scenarios/bundles/` named `<bundle-id>.json`
- Updated `backend/server.js` to dynamically load scenario and bundle files from their respective directories
- Updated documentation in `scenarios/SCHEMA.md` and `README.md` to reflect the new repository layout and contributor workflow
