The OpenSky "Default bounding box" now follows where flying happens. A new "Automatic" picker mode (the default) resolves the live-map area from a location cascade — drone telemetry → phone GPS → browser geolocation → the user's Region country → Europe — instead of a fixed box. Manual presets and Custom coordinates still work. - Web App: new shared countries.js dataset (all countries + bbox, offline point→country); the bbox picker gains all European countries and an Automatic option (client pref prefs.autoBbox); the Region setting expands from 6 locale entries to all countries; the live map resolves the cascade each poll and sends it as ?bbox=. - API Server: the states endpoint accepts and validates a ?bbox= override (validBBox); the Web App BFF forwards the query; the hub relays new phoneLatitude/phoneLongitude telemetry to the Web App. - Fly App: reports the phone's own GPS (geolocator) alongside telemetry, used as the "your location" fallback. - API panel: the OpenSky bbox picker lists all European countries. Builds verified across web, panel, both Go modules and the Fly App APK. Region list, Automatic default and the cascade ?bbox= override verified in the browser.

Web App (Control Panel)
The PilotVault control-panel BFF. It serves the embedded Vue single-page app and
proxies /bff/* to the API Server, so the browser only ever talks to this
server (same-origin). The API Server is the gateway to PocketBase and to the live
Fly App data; the browser never contacts either directly.
Layout
server/ # Go BFF (package main) — proxies /bff/* and serves the SPA
dist/ # built web assets (go:embed target — produced by the web build)
.env.example # configuration template
go.mod
main.go # entrypoint, routing, static serving
bff.go # /bff/* proxy handlers
web/ # Vue 3 + Tailwind source, built by Vite into ../server/dist
Configuration
See server/.env.example. Key variables:
ADDR— address the BFF listens on (default:8090).API_BASE— default API Server the BFF proxies to (defaulthttp://localhost:8080). Users can override this per-session at login.
Develop
# 1. Build the web app into server/dist (embedded by the Go binary)
cd web && npm install && npm run build && cd ..
# 2. Run the BFF
cd server && go run .
For a live UI with hot-reload, run npm run dev in web/ (it proxies /bff to
a locally running BFF on :8090).
Build
cd server && go build -o web-app .
Or build the container image (multi-stage; builds the web app then the binary):
docker build -t pilotvault-web-app .
