Closes#520, #514, #443.
## #520 / #514 — stale Docker image, missing UI assets
`ruvnet/wifi-densepose:latest` was published before `ui/observatory*` and
`ui/pose-fusion*` were added; users see /app/ui missing those files and the
v0.6+ packet format doesn't reach the server. Two fixes:
1. `docker/Dockerfile.rust` now `RUN`s a build-time guard after `COPY ui/`
that fails the build if `index.html` / `observatory.html` / `pose-fusion.html`
/ `viz.html` (or the `observatory/` / `pose-fusion/` / `components/` /
`services/` directories) are missing, plus an exec-bit check on
`/app/sensing-server`. A stale image can never be silently produced again.
2. New `.github/workflows/sensing-server-docker.yml` rebuilds + pushes on
every change to the Dockerfile, the server crate, the signal/vitals/
wifiscan crates, the workspace manifests, the `ui/` tree, or itself —
plus `v*` tags and manual dispatch. Pushes to both `docker.io/ruvnet/
wifi-densepose` AND `ghcr.io/ruvnet/wifi-densepose` with `latest` +
`vX.Y.Z` + `sha-<short>` tags, then post-push smoke-tests the artifact:
/health, /api/v1/info, the observatory + pose-fusion HTML, AND the
bearer-auth path (no token → 401, wrong → 401, correct → 200). Uses the
`DOCKERHUB_USERNAME`/`DOCKERHUB_TOKEN` repo secrets; ghcr.io rides on
the workflow's GITHUB_TOKEN.
## #443 — sensing-server REST API auth model
QE security audit raised that 40+ /api/v1/* routes have no auth layer with
a default `0.0.0.0` bind. New `wifi_densepose_sensing_server::bearer_auth`
module + middleware:
- Env-var-gated: `RUVIEW_API_TOKEN` unset/empty ⇒ middleware is a no-op
(current LAN-mode behaviour preserved — **no default change**); set ⇒
every `/api/v1/*` request must carry `Authorization: Bearer <token>`
or the server returns 401.
- Constant-time byte compare via local `ct_eq` (no new dep).
- `/health*`, `/ws/sensing`, and `/ui/*` are intentionally never gated
(orchestrator probes + local browsers).
- Startup logs which mode is active and warns when auth is ON with a
`0.0.0.0` bind.
- 8 unit tests on the middleware via `tower::ServiceExt::oneshot`
(sensing-server lib tests 191 → 199, 0 failures).
Verified locally: `cargo build --workspace --no-default-features` ✓,
`cargo test -p wifi-densepose-sensing-server --no-default-features` ✓.
