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.

- protocol: Closing+Inbound no longer force-transitions to Closed after
one packet; handle_inbound now owns the transition when it receives a
Close frame, preventing data loss on in-flight packets during teardown.
Add Tick handling for Closing state so the Close frame is retransmitted.
- protocol: replace sent_history VecDeque<SentFrame> with BTreeMap<u64,
SentFrame>; NACK lookup is now O(log n) instead of O(n) linear scan.
- protocol: remove unused _mtu field; drop VecDeque import.
- congestion: remove no-op on_tick method (was never called).
- dispatcher: remove broad #[allow(dead_code)] on impl block; annotate
three genuinely unused methods individually. Fix comment "100000
entries" → "50000" and log "inactive >5min" → ">10min" (real timeout
is 600 s). Remove unused mut on stream variable in ostp client.
- docs: correct timestamp window ±30 s → ±300 s in EN and RU specs to
match the actual drift > 300 check in dispatcher.
