Lands sections 3-5 of the relocate-brouter-to-dedicated-host change:
everything needed to run BRouter on the dedicated Hetzner Robot host
and have the Planner talk to it with the shared-secret header. Does
NOT flip the cutover — the flagship BRouter stays warm during soak.
## BRouter host compose (section 3)
New `infrastructure/brouter-host/` — a standalone compose project that
runs as the `trails` user on `ullrich.is`:
- `docker-compose.yml` — brouter + caddy sidecar. BRouter has no host
port; caddy binds only to `10.0.1.10:17777` (vSwitch IP). Every
service explicitly overrides the host's default Loki logging driver
to `json-file` so logs don't leak to the operator's personal Loki.
- `Caddyfile` — single-purpose reverse proxy that requires
`X-BRouter-Auth: ${BROUTER_AUTH_TOKEN}` on every request. `auto_https
off` (vSwitch-only); default access log format omits request
headers, so the token is never written to disk.
- `download-segments.sh` — crawls brouter.de, pulls planet-wide RD5
tiles via `wget -N` (incremental). Idempotent, safe to cron.
- `README.md` — one-shot provisioning + token rotation + rollback
notes.
`docker/brouter/Dockerfile` is patched to honor `JAVA_OPTS` (was
hardcoded `-Xmx1024M` in CMD). Default keeps the flagship's current
heap; compose on the dedicated host overrides to `-Xmx8g` for planet
scale on a 32 GB box.
## Planner shared-secret header (section 4)
`apps/planner/app/lib/brouter.ts`:
- Module-level guard: throws at startup in production if
`BROUTER_AUTH_TOKEN` is unset.
- `authHeaders()` helper (reads env at call time, so tests can
`vi.stubEnv` without module reset).
- Header attached on both `computeRoute` (per-segment) and
`computeSegmentGpx`.
3 new unit tests cover header attachment + the no-token path.
`infrastructure/docker-compose.yml` passes `BROUTER_AUTH_TOKEN` to
the Planner service, and makes `BROUTER_URL` overridable via SOPS so
the cutover is a one-variable flip.
## cd-brouter workflow (section 5)
Rewritten to deploy to the dedicated host:
- SSH as `trails@${BROUTER_DEPLOY_HOST}` on port
`${BROUTER_DEPLOY_SSH_PORT}` (2232) using
`${BROUTER_DEPLOY_SSH_KEY}`.
- Decrypts SOPS, extracts ONLY `BROUTER_AUTH_TOKEN` into a `.env`
file, scp'd alongside the compose project.
- `paths:` trigger now includes `infrastructure/brouter-host/**`.
- Segment download is NOT run here — first-time seed is a manual
operator step (multi-hour). Routine re-runs are cron-able on the
dedicated host.
- Grafana annotation step preserved (reaches flagship Grafana as
before).
## What's NOT here
- `brouter:` service on the flagship is intentionally left in place
(removed in section 7.5 after the 48 h soak window post-cutover).
- Observability (section 6) — Prometheus scrape + Loki shipping from
the dedicated host — comes in a follow-up PR.
- Cutover itself (section 7) — flip `BROUTER_URL`, verify, remove the
flagship brouter — is an operator action gated on first-time
provisioning + smoke testing.
## Verification
`pnpm typecheck && pnpm lint && pnpm test` all clean; planner build
passes (the CI regression from #286 was fixed in #290).

Extract highway=* tags from BRouter tiledesc messages alongside surface
data and add a new "Road Type" color mode that colors the route polyline
and elevation chart by OSM highway classification (cycleway, residential,
path, etc.). Includes color palette, legend, hover labels, i18n (EN+DE),
unit tests for tag extraction, and E2E tests.

- Enrich BRouter response with per-point 3D coordinates and segment boundary
tracking (EnrichedRoute interface)
- ColoredRoute component: plain, elevation gradient (green→yellow→red), and
surface color modes with invisible wide polyline for click targeting
- Click-to-split: click on route polyline inserts waypoint at nearest point,
mapped to correct segment via boundary indices
- MidpointHandles: draggable CircleMarkers at route segment midpoints for
reshaping, hidden below zoom 12, opaque on hover
- Color mode toggle (select) synced via Yjs routeData
- i18n keys for color mode labels (en + de)
- Unit tests for segment boundary tracking (13 tests)
- E2E tests for enriched route response and color mode toggle

Waypoint drag:
- Use observeDeep instead of observe to detect Y.Map property changes
Host election:
- Extracted to host-election.ts with 8 unit tests
- Simple rule: lowest real client ID is always host, deterministic
- Always sets role (host or participant), no missing roles
- Filters server docs (empty awareness state) from election
BRouter routing:
- Route segment-by-segment like bikerouter.de (one request per
waypoint pair), guarantees route passes through every waypoint
- Merge GeoJSON segments with accumulated stats
- 8 unit tests for segment merging and waypoint splitting
Awareness cleanup:
- Track client IDs per WebSocket connection
- Immediately remove awareness on WebSocket close
Debug panel:
- Visibility + expanded state persisted in localStorage
- Hotkey (Shift+Cmd+Option+T) toggles visibility
- Labels server docs as (server)
- All logic self-contained in YjsDebugPanel.tsx
User identity:
- Color and name persisted in localStorage across reloads
Tests: 32 total (16 existing + 8 host election + 8 routing)
