The helper logged "exiting" but never terminated: the WinTun blocking
receive runs on a thread that task.abort() cannot cancel, so it kept the
ostp_tun adapter (and its metric-0 default route) alive and hung the tokio
runtime as a zombie. The next connect then faced two competing default
routes and failed to install the per-server /32 bypass, so the client's own
handshake packets looped back into the dead tunnel — every OSTP handshake
timed out and there was no internet.
- ostp-tun-helper: std::process::exit(0) after run_server returns so the
kernel reclaims the adapter and all routes bound to it.
- ostp-tun/windows_route: dedupe bypass IPs, purge any stale /32 for the
dest before adding (enumerate + delete), and log add failures at warn!
instead of debug! so the cause is visible in the INFO-level helper log.
- ostp-tun/windows: keep .destination() LUID default route (reliable
capture) alongside the racy friendly-name route; retry create() through
the transient ERROR_INVALID_PARAMETER window.
- ostp-client: wire BridgeMetrics.connection_state through runner and
inbounds so the GUI reflects connecting/connected/disconnected.
- ostp-gui: parse JSONC config (strip // and /* */) in the settings view.

- Implement DnsTransportClient and polling logic
- Implement DnsTransportServer for TXT/NULL record handling
- Add dns_prober to find best public resolvers by region
- Update React GUI (Desktop) to support DNS Proxy and i18n
- Update Flutter App to support DNS Proxy settings
- Update CLI Setup Wizard to generate new v0.3.1 config with dns_transport block
- Add Wiki documentation for DNS Transport
TUN Interface:
- Fixed adapter name to always be 'ostp_tun' by cleaning up stale
adapters before launch (prevents 'ostp_tun 2', 'ostp_tun 3', etc.)
- Parallelized route setup with tun2socks launch to save ~3 seconds
- Replaced fixed 2-second sleep with adapter readiness polling
- Added -NoProfile to all PowerShell calls for faster execution
Speed:
- Reduced handshake timeout from 10s to 5s
- Reduced tun2socks spawn buffer from 300ms to 0 (removed)
GUI:
- Added i18n support: English and Russian translations
- Language toggle button in header (EN/RU)
- Merged 'IP Ranges' field into 'Bypass IPs / CIDR Ranges'
- Removed separate IP ranges field
- All static text uses data-i18n attributes
- Status messages, labels, toasts all translated
- Replaced alert() calls with toast notifications
CI/CD:
- Added separate GUI build job for Windows x64 and arm64
- Produces ostp-windows-gui-{arch}.zip with: ostp-gui.exe + wintun.dll + tun2socks.exe
- Uses Tauri CLI v2 for build
