* [client] Close the session-expiration dialog only on an actual session renewal
The dialog auto-closed on any Connected status snapshot, but the daemon
emits Connected periodically regardless of session state, so the warning
popup disappeared on the next snapshot (~30s) with no chance to
re-authenticate. Close only when the snapshot's session deadline jumps
past the one the dialog was opened for, meaning the session was renewed
from another surface (tray action, CLI, main window).
* [client] Compare session renewals against the exact deadline in the expiration dialog
The dialog reconstructed its reference deadline from the relative seconds
URL parameter, which carries up to a second of truncation and mount
latency, forcing a renewal-detection margin wide enough to miss a renewal
made shortly after the previous login. Pass the absolute deadline (unix
ms) from both tray call sites - the extend flow's cached deadline and the
final warning's event metadata - so any forward jump in the snapshot
deadline closes the dialog; the seconds-derived fallback with a small
tolerance remains for an unknown deadline.
* [client] Derive the expiration dialog countdown from the deadline
The per-second decrement assumed the interval fires once a second, but
the webview's timers get suspended for tens of seconds under App Nap /
hidden-window throttling, leaving the displayed countdown behind the
wall clock by the suspended time. Recompute the remaining time from the
absolute deadline on every tick so the first tick after a suspension
shows the correct value.
* [client] Tolerate the warning deadline's second precision in the renewal check
The final-warning metadata formats the deadline as RFC3339 truncated to
whole seconds while the status snapshot keeps millisecond precision, so
an unchanged deadline could appear up to 999 ms newer than the exact URL
value and close the dialog on the first snapshot. Allow a sub-second
tolerance on the exact path; any real renewal jumps by at least seconds.
The main and Settings windows were created at startup and kept alive hidden on close, so an idle tray held two webview processes for surfaces the user may never open. Both are now built on first show and destroyed on close, which takes the idle footprint on macOS from ~160 MB to ~74 MB.
The WindowManager owns creation: it rebuilds the main window on the next show and hands out live pointers, since a stored one goes stale. Every show is deferred until the frontend reports it has rendered, so a freshly created window is never on screen empty, with a timeout so a frontend that never reports cannot strand a window hidden.
Files move directly between peers over the overlay, with no server in the
path. The receiver listens on the WireGuard address only, so the port is
unreachable from outside the tunnel, and every offer is matched to a known
peer before anything is read.
Consent is the default: an offer carries metadata alone, and no payload
moves until the receiver accepts. Policy is per profile and device-local —
off, ask, or auto-accept, with per-sender exceptions on top.
Policy and history live in the profile's preferences, so removing a profile
takes its file drop state with it. Transfers interrupted by a restart are
settled on load; nothing survives to finish them, and left alone they would
sit in the log as permanently pending.
The Android bindings pull payload bytes through a chunk-returning stream:
gomobile copies a []byte argument into a fresh Java array and never copies
it back, so a fill-my-buffer method would hand back the right length with
no data.
## Describe your changes
After the SSO session expires, the daemon tears the engine down
permanently
(management returns `PermissionDenied` → `runCancel()` → the retry loop
exits
for good). The "Session expired" dialog's Login button still drove the
extend-session flow, which requires a live engine: the user completed
the full
browser SSO + 2FA round trip only to get
`Failed to extend the session — engine is not initialised`, with no way
out
other than quitting and relaunching the client.
Reproduce:
1. Log in on a desktop client with session expiration enabled (e.g. 16h
TTL).
2. Let the session expire (e.g. leave the machine asleep overnight).
3. Wake it, click **Login** on the "Session expired" dialog, complete
SSO + 2FA.
4. The error dialog appears and every retry fails the same way.
Changes:
- The expired branch of the session-expiration dialog now emits
`trigger-login`, driving the full `Login → SSO → Up` sequence that
rebuilds
the client, instead of the extend flow (an expired session can no longer
be
extended).
- `RequestExtendAuthSession` fails fast when the engine is already gone,
so the
browser/2FA round trip is not wasted on a doomed extend.
- The expired tray row navigated the main window to `/#/login`, a route
that
does not exist and fell through to the main page without starting a
login;
it now emits `trigger-login` as well.

## Summary by CodeRabbit
- **Bug Fixes**
- Improved session extension handling when the client engine is
unavailable by prompting users to log in again.
- Updated expired-session behavior to trigger the standard login flow,
providing a more consistent sign-in experience.
<!-- end of auto-generated comment: release notes by coderabbit.ai -->
- **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.
