The v0.1.4 Origin fix cleared only the first of two gates in /api/ws's
preHandler. The second, req.jwtVerify(), reads the HttpOnly cookie — which
tauri-plugin-websocket (a bare tungstenite client, no cookie jar) can never
send. Every desktop handshake 401'd and use-live-feed reconnected every 10s
(confirmed in the park-2 server log).
- routes/ws.ts: POST /api/ws/ticket (cookie + CSRF auth) mints a 30s,
single-use, in-memory ticket; the WS preHandler accepts it via an
x-ws-ticket header after the Origin check, then the same report:read
role check. Browser cookie path unchanged; JWT stays out of JS.
- platform-ws.ts: fetch a ticket before connect, send it with the Origin
header; connect failures now go through logClient (rate-limited).
- logger.ts: flush read the CSRF token from document.cookie, null on
desktop, so every desktop POST /api/logs 403'd and was dropped silently —
no desktop client log had ever reached app_logs. Stash moved to a
dependency-free lib/desktop-csrf.ts shared by api.ts and logger.ts.
- backend-config.ts: ConnectScreen probe uses the unauthenticated /health
(now also returns app: "parking-system") instead of accepting any 401.
- README: local-AppImage release gate — tauri dev runs at
http://localhost:5173, not tauri://localhost, so none of these
origin-dependent bugs reproduce there.
- wiki: new section + log entry; four citation corrections.
Requires the server image with this commit deployed before the new desktop
build connects (the ticket endpoint must exist).

The desktop shell is one generic .deb/.AppImage distributed via
mca/public_releases, not built per-booth, but the backend origin was baked
in at build time (VITE_API_BASE, hardcoded to http://127.0.0.1:3000) — the
same installer could never point at a different appliance without a
rebuild.
Adds ConnectScreen (shown before Login in Tauri when no backend is saved),
backed by tauri-plugin-store persisting the operator-entered URL across
restarts. CSP's connect-src tightens to 'self' only — all backend traffic
already routes through tauri-plugin-http/websocket, which run Rust-side
and are outside connect-src's reach anyway — and the real access boundary
moves to capabilities/default.json's http:default scope, wildcarded so an
operator-chosen host is actually reachable. Adds a "Change server" control
in Setup (desktop-only) to repoint an already-configured install.
While tracing the desktop auth path for this: tauri-plugin-http's fetch()
runs through Rust's reqwest, which keeps its own cookie jar separate from
the webview, so document.cookie on tauri://localhost never sees the
parking_csrf cookie the server sets (open upstream bug,
tauri-apps/tauri#13045/#11518). This means the desktop app has likely been
silently sending no CSRF header on every mutation since the shell was
first built — pre-existing, independent of this change. Fixed by having
sessionView() (routes/auth.ts) also echo the CSRF value in the login/me
JSON body; the desktop client stashes it in memory and echoes that instead
of reading document.cookie. assertCsrf() itself is untouched.
Verified end-to-end against a real LAN-bound dev server: login returns a
csrfToken matching the cookie, a mutation using the body-sourced token in
X-CSRF-Token succeeds (200), and the same mutation without it still
correctly 403s.
