Say what the e2e's WebRTC assertion actually proves
go2rtc is not running in this test, so the gateway cannot reach it and the message "its go2rtc answered (as a refusal)" was wrong. What the assertion really establishes is that the offer travelled cloud -> uplink -> gateway at all, which a timeout would not. Records that the happy path was verified by hand - the real go2rtc and a valid offer return 200 with an answer SDP carrying go2rtc's own host and server-reflexive candidates - and why that is not automated here: it needs a live camera and go2rtc installed, and this script should not depend on either. |

Relay camera signalling and mint TURN credentials
Makes the printer cameras playable from a hosted console, which they were not: GET /printers/:id/stream handed out the gateway's own LAN address, and a browser cannot use it. go2rtc sends no CORS headers and checks its API password before CORS, so a browser's unauthenticated preflight gets a 401 (measured against 1.9.14), and a gateway is behind a workshop NAT anyway. That endpoint could only ever have worked for an operator standing on the same network, and offered everyone else a player that silently never loaded. So /:id/stream now returns a camera name and short-lived ICE servers, and POST /:id/webrtc relays the offer to the gateway over the socket it already holds open and returns go2rtc's answer. Media travels browser-to-gateway through the TURN relay, DTLS-SRTP encrypted, so neither this process nor Cloudflare can read it - which is why this is signalling rather than proxying fMP4 through the API. That alternative also needed a credential in the URL, because <video> cannot send an Authorization header. Only the browser gets TURN credentials. It is pinned to relay-only, so it allocates the relay and go2rtc sends to it; one side is enough. That keeps rotation on a per-viewer request instead of in go2rtc's config, which is read once at startup - rotating there would restart it and drop every viewer on a timer. Unconfigured TURN is supported rather than fatal, unlike R2: a viewer on the gateway's LAN connects on host candidates. turnConfigured is returned alongside, because empty iceServers means "not set up" in one case and "minting failed" in the other, and those need different answers. Camera negotiations are failed immediately when a gateway disconnects, rather than waiting out the 12s timeout - a browser is holding a request open on each one. getStreamBaseUrl is kept but no longer served to anyone: gateways still report the field and it is the only record of where one thinks it is reachable, which is useful when diagnosing one. e2e-edge.sh asserts the new shape, that no streamUrl comes back, and drives a real offer through the relay - asserting the refusal came from go2rtc rather than from a timeout, since that is what proves the round trip happened. |

Refuse to boot without R2 credentials
`?? ""` on the access key and secret meant a deployment with no object storage configured started happily, and `POST /jobs` handed clients presigned URLs signed with an empty key. The first sign of trouble was a 403 from R2 - either in the client's uploader or, worse, inside a gateway that had downloaded R2's XML error document in place of a print. Nothing in that chain said "R2 is not configured". Reads both credentials through a `required()` that throws, naming the variable, mirroring auth/verifier.ts and auth/edge_secret.ts. The endpoint is read with `||` rather than `??`, because the committed template ships `R2_ENDPOINT=` empty and `??` only catches null - so an empty value was taken as a real endpoint and the account-id derivation never ran. That is the trap auth/edge_secret.ts documents, and it caught this line too, in the first draft of it. A test covers the derivation. Each boot-failure test fills every other variable so the one under test is the only thing missing; otherwise whichever variable is read first wins and the assertion passes for the wrong reason. e2e-edge.sh gains dummy values, since it boots the backend. It presigns nothing, so they only have to exist. |

Add the operator console's live telemetry socket
The only socket until now was the gateway-facing /ws/edge/v1, which
authenticates as a *farm* with a credential any of its gateways holds,
and which accepts telemetry. Pointing a browser at it would mean handing
the browser something that can drive printers. /ws/telemetry
authenticates as a *user* with a Supabase access token, and accepts
nothing at all: it is push-only, and a frame arriving from the browser is
ignored. Everything that changes a printer keeps going over HTTP, where
the role checks and the audit trail already are.
Auth is checked at the upgrade, as on the edge socket, so an
unauthenticated browser never gets a socket. The token rides in
`Sec-WebSocket-Protocol` - `new WebSocket(url, ["bearer", token])` -
because that field is the whole of what JavaScript controls about a
browser handshake, and the usual workaround of `?token=` would put a
bearer credential into every access and proxy log. "bearer" is first
because the runtime echoes the *first* offered value back in the
response header, so the token must not be in that position; asserted,
not assumed.
The payload is the printer resource itself, returned straight out of
`persistTelemetry`'s UPDATE through `printerProjection` - the same
projection the REST routes use. So a push is byte-for-byte what
`GET /printers/:id` would have answered, and a client applies it to the
row it already holds. Rebuilding it from the gateway's snapshot instead
would be a second translation of the same data, free to drift, and
missing the columns a gateway never reports at all like `name` and
`vendor`.
`maySee` is what keeps one organisation's telemetry out of another's
console, and it lives in `telemetry/broadcast.ts` with no imports but a
type so it can be tested without a socket or a database - the same reason
as `dispatch/job_status.ts`, `stream.ts` and `auth/edge_upgrade.ts`. It
refuses a printer with no farm rather than matching it against anything,
which no row can be today, because this is the one function where being
wrong leaks another org's machines.
**A latent bug this turned up:** the edge route's resolve was
`{ as: "scoped" }`, copied from `requireUser`. For `requireUser` that is
right - it is used inside each route file and must propagate `user` to
that file's routes. On a ws plugin it propagates the check to the parent
app, where it gates every route mounted *after* that plugin. Measured
with a two-plugin probe: the second plugin's own socket is refused
because the first one's check runs first and finds no edge token. Nothing
shipped broken only because /ws/telemetry is the first route mounted
after it - and it was refused outright until this was found. Both ws
resolves now use the default `local` scope.
Known limits, both written down rather than discovered later:
- **In-process fan-out.** A `Set` of callbacks in one process, so two
backend instances would each push only the telemetry their own
gateways are connected to and an operator would see half a fleet. The
fix is Valkey pub/sub, already a dependency; doing it now would mean
testing a message broker to deliver events between two objects in the
same process.
- **Visibility is resolved once, when the socket opens.** Re-deriving it
per message would put a database round trip on every push to every
viewer. The direction that matters: someone removed from an
organisation keeps receiving its telemetry until their socket drops.
Closing that needs a signal on membership change that this backend does
not have; a periodic re-resolve would narrow the window without closing
it. Telemetry is also the least sensitive thing here, and every HTTP
route re-checks on each request.
Verified against the real stack, not just mirrored in unit tests:
`scripts/e2e-edge.sh` now drives the actual route with a real
JWKS-verified token and asserts the handshake echoes "bearer", that a
`ready` frame arrives, and that a real push carries the printer resource
with live readings - "2 push(es); last was H2C state=FINISH nozzle=30
camera=h2c". A bogus token is refused before any socket exists.
`scripts/watch-telemetry.ts` is the client it uses, and is the quickest
way to see by hand whether a farm's telemetry reaches a console.
110 tests (was 95), `bunx tsc --noEmit` clean.

Cover the camera path in the edge e2e test
The camera work had unit tests on both ends and nothing exercising it
against a real printer. This adds that, and it immediately earned its
keep: it is the only test that covers `stream_base_url` surviving the
hello, living on an in-memory connection, and coming back out of
`GET /printers/:id/stream` - a path with no unit test behind it, because
the connection map is not reachable without a socket.
Verified against a live H2C: it reports a camera stream named after its
own gateway id, and the endpoint answers
`{"streamUrl":"http://e2e-gateway.invalid:1984","cameraId":"h2c"}`.
Both halves are asserted, because "some printers have a stream and most
do not" is the expected state rather than a defect. Only the X1/H2 class
publishes an `rtsp_url` - confirmed at the network layer, where the H2C
accepts TCP on 322 and a P1P refuses it and listens on 6000 - so the
test also asserts that a printer without one is refused with a 404 that
blames the printer's camera and not the gateway. A run where no printer
has a camera still passes, but says so rather than claiming the path
works.
`CONTINUUM_STREAM_BASE_URL` is set to an unreachable name on purpose:
nothing here plays video, and it only has to prove the value made the
round trip. The gateway's go2rtc config is also pointed into the
scratch directory now, so a run no longer writes `go2rtc.yaml` into the
proxy checkout.

Authenticate and authorize every route: org layer + Supabase JWKS
Until now every HTTP route was unauthenticated. A probe against the
running server returned a farm's `edgeProxyToken` and a printer's
`accessCode` to an anonymous caller, and that pair is enough to connect
as a farm's gateway and drive its printers. The previous commit stopped
the credentials appearing in responses; this one makes the routes ask
who is calling.
Authentication. Access tokens are verified against the Supabase
project's published JWKS via `createSupabaseJwtVerifier` from
`@continuum/ts-core`: RS256, public key only, no secret in this
process. It replaces the HS256 `@elysiajs/jwt` path, where
`SUPABASE_JWT_SECRET` was simultaneously the verification key and a
key that could mint tokens, present in the environment of every
instance. `src/auth/verifier.ts` builds it at module load so a
misconfigured deployment fails at boot rather than on first login.
The edge-gateway token stays symmetric and that is not an
inconsistency: this service is both its issuer and its only verifier,
so there is no second party to keep a secret from. It now carries an
`exp`, which it did not, despite the response saying
`expiresInSeconds: 3600`.
Tenancy. An org layer above farms - `organisations`,
`org_members(org_id, user_id, role)`, `farms.org_id` - so a farm can
have more than one operator without sharing an account. `farms.owner_id`
is gone. Authorization is one rule applied everywhere: resolve the
thing being acted on back to an organisation and check the caller's
role there, user -> org -> farm -> printer, with nothing in between
carrying permissions of its own. The ladder is
`viewer` < `operator` < `owner`; printer commands and job submission
need `operator`, because they move physical machines, and that is the
one boundary here that is not about data.
A non-member gets 404, not 403: a 403 would confirm that a given farm
or printer id exists and belongs to someone, which is an enumeration
oracle over the whole system. 403 is kept for a member who may see the
record but not do this to it.
List endpoints scope in the `where` clause, not after the query - a
filter applied to the result is one `return` away from being skipped.
They are also bounded now (`limit`/`offset`, default 50, max 200
refused rather than clamped).
`ownerId` and `submittedBy` no longer come from request bodies. Nor do
the printer telemetry columns: `POST /printers` is narrowed to the
columns a client owns, because a client that could POST
`status: "idle"` could make the scheduler send work to a printer that
is mid-print.
Also fills the CRUD gaps that made the API unusable - PATCH and DELETE
for farms, printers, jobs and orgs, and membership management - plus
one error shape for the whole API via `toErrorResponse`, so an
authorization failure is a throw that leaves the handler rather than a
status somebody has to remember to set.
Guards on the two changes that cannot be undone through the API:
removing or demoting an organisation's last owner, and deleting an
organisation while farms are still attached (it would cascade to every
printer, print job and stored frame).
Migration 0001 is hand-edited after generation. drizzle-kit emitted
`ADD COLUMN org_id uuid NOT NULL`, which cannot apply to a populated
table, and dropped `owner_id` without moving what it encodes anywhere.
It now adds the column nullable, creates one organisation per distinct
legacy owner with that user as its `owner` member, points each farm at
it, and only then tightens the column and drops `owner_id`. Verified
both ways: from empty via `drizzle-kit migrate`, and against a seeded
database where two farms shared an owner and a third did not.
Testing. `scripts/dev-auth.ts` is a local RS256 issuer publishing a
JWKS at the path the backend fetches, so the real verification path is
testable without a Supabase project. The alternative was a test-only
bypass in the backend - an env var making it trust an unsigned token -
which would be a permanent hole one misconfiguration from production,
and would mean the code under test is not the code that ships.
- `tests/authz.test.ts` (19 tests): the role ladder written out in full
rather than derived the same way the implementation derives it, and
the real JWKS path - a token signed by a key outside the JWKS, an
expired token and a token with `aud: "anon"` (Supabase's own anon key
is a valid project JWT) are all rejected, with the same message, so
probing cannot tell which part of a forged token to fix next.
- `scripts/e2e-authz.sh` (68 assertions, real Postgres, real routes):
four users across two organisations; anonymous 401s, cross-org 404s,
viewer-cannot-command, operator-cannot-rotate, a spoofed
`submittedBy` in the body ignored, no credential in any read, and the
rotated token still minting an edge JWT.
- `scripts/e2e-edge.sh` updated for the org layer and now authenticates
as a seeded `operator` - the weakest role that should work, so the
run would fail if the command boundary were not where it claims to
be. Re-verified against both live printers: telemetry from `h2c` and
`p1p` persisted, and an authenticated `set_fan_speed` went
HTTP -> WebSocket -> MQTT -> P1P and back `ok:true`, fan returned
to 0.
Two bugs found in the test scripts while writing this, both the same
shape as the earlier `pkill -f` incident: `kill "${PID:-0}"` with an
unset PID signals the whole process group, including the harness, and
`uuidgen` is not installed in this sandbox.

Add a runnable dev environment, and fix the pins that stopped it booting
The edge route had never been run. Adding a way to run it turned up that the server could not start at all, for two independent dependency reasons that typechecking could not see: - `elysia: ^1.1.26` had resolved to 1.4.30, which calls `t.Module` - a TypeBox 0.34 API - while this repo pinned TypeBox 0.33. `t.Module is not a function`. - `drizzle-typebox: ^0.2.1` resolved to a version whose peers demand `drizzle-orm >= 0.36`, against the `^0.33.0` pinned here. Importing it threw `Export named 'getViewSelectedFields' not found`. Both are caret ranges that drifted into combinations nobody chose. elysia, @sinclair/typebox and the drizzle packages are now pinned tightly, TypeBox forward to 0.34.52 (which satisfies Elysia and drizzle-typebox 0.1.1 alike), and tests/dependency_identity.test.ts fails if the TypeBox version ever differs between here and @continuum/ts-types - the skew that made every shared schema invalid, with an error message pointing at Standard Schema instead. Dropping to drizzle-typebox 0.1.1 widens `jsonb` in the generated validators, so `metadata` needs an explicit object shape in validators.ts; the column is declared `$type<Record<string, unknown>>()` and a validated body otherwise is not assignable to `.values()`. scripts/: - `install-docker.sh` - one-time host setup, kept separate because it touches the machine rather than containers. - `dev-env.sh up|down|reset|status|psql|schema|env` - Valkey + Postgres/pgvector. Uses docker-compose.yml when a daemon answers, and otherwise runs the same two services from apt. That fallback is not hypothetical: Docker cannot run in this sandbox at all. dockerd needs CAP_NET_ADMIN to build its bridge; with `--bridge=none --iptables=false` it starts but cannot unpack an image without CAP_SYS_ADMIN; with `--storage-driver=vfs` it still fails because registering a layer needs user namespaces, which are blocked outright. All three are host-level grants, so no script can work around them - hence a second path rather than a broken first one. - `e2e-edge.sh` - the test the unit tests cannot be. Seeds a farm, claims its printers, mints an edge token, runs the real continuum-proxy, and asserts live telemetry reached Postgres and a command reached a printer. It only sends a fan speed, only to a printer reporting IDLE, and puts it back afterwards. - `capture-gateway-frames.js` - records what a gateway really sends, for refreshing tests/fixtures/. Read-only unless FAN_TEST_PRINTER is set. The test comment referred to this before it existed. Verified end to end, from a dropped and freshly migrated database: `h2c` persisted as printing/RUNNING 22% layer 2/25 nozzle 230 bed 35 with 3 HMS alerts, `p1p` as idle/IDLE, and `POST /printers/:id/commands` reached the P1P's fan and came back ok:true. An unclaimed printer is refused 409 PRINTER_UNREACHABLE rather than guessed at. Two things the e2e script got wrong first, both now fixed in it: it waited for the first printer row instead of all of them, which silently tested only the v2 printer (a v1 Bambu reports one tick later); and `$!` after `( cd ... ) &` is the subshell, so cleanup left an orphaned gateway reconnecting with a token for a deleted farm and polluting the next run. Note: `drizzle/` is gitignored, so the generated migration is not committed and there is no migration history in the repo. Left as-is deliberately - that is a workflow call, flagged in PLAN.md. |
