The tray session row flapped on every transient engine restart and went
blank at the exact moment the session expired:
- Watcher.Close zeroed the server-scoped recorder deadline on every
engine restart (sleep/wake, network change, stream errors), hiding the
tray row until the next successful login re-seeded it. Close now only
stops the timers; the client run loop clears the recorder when it
exits for real.
- Status.GetSessionExpiresAt masked past deadlines as zero, so the
status snapshot dropped the field right when the UI should have shown
"session expired". The getter now returns the raw value and the tray
renders past deadlines as "Session expired — sign in again", routing
the click to the login flow.
- The watcher rejected recently-expired deadlines (30s skew) delivered
by login/sync, clearing the recorder instead of surfacing the expiry.
Deadlines up to 30 days past are now recorded as expired; only older
values are rejected as garbage.
- **Wails v3 application** (`client/ui`) with a React + TypeScript + Tailwind frontend replacing the Fyne UI: main connection view, exit-node switcher, networks/peers browser with detail panels, profile management, settings (general, network, SSH, security, troubleshooting, appearance), debug-bundle creation, and a first-run welcome flow.
- **Internationalization**: go-i18n bundle with 9 locales (en, de, es, fr, hu, it, pt, ru, zh-CN) shared between the tray and the frontend.
- **New system tray** implementation with per-platform theme-aware icons, including a native XEmbed host for Linux (`xembed_tray_linux.c`) and a Linux theme watcher.
- **Session handling**: auth session watcher (`client/internal/auth/sessionwatch`), pending login flow, session-expiration dialog and tray notifications, and `netbird login` improvements.
- **Daemon API extensions** (`daemon.proto`): status stream subscription, event stream, networks/exit-node selection endpoints, and richer full status — with probe throttling on the daemon side to protect against UI-driven request storms.
- **UI preferences store** persisted per profile, autostart management via the daemon (single source of truth in HKCU on Windows).
- **Build system**: Taskfile-based builds per platform (macOS, Linux, Windows), Docker cross-compilation images, MSIX/NSIS/nfpm/AppImage packaging, and a new `frontend-ui` CI workflow.
