From 13c7743d4846a3c3868e2b4ef0e6921ab11a0d25 Mon Sep 17 00:00:00 2001 From: Breadway Date: Wed, 26 Aug 2026 19:30:41 +0800 Subject: [PATCH] Add feature batch: captive-portal detection, schedules, exit-node failover, 802.1x, per-network DNS MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements the planned feature sweep: tri-state connectivity with portal detection, time-based profile schedules, priority exit-node list with failover, enterprise (802.1x) network support, per-network DNS, signal- aware selection, auto-learn markers, suspend/resume recovery, prune command, scored detection, and richer bread events (network.changed, tailscale.changed). CLI gains --json output, init --wait, and add --dns/ --eap/--identity/--ca-cert. Adds regression coverage for each feature; 141 tests pass and clippy is clean with -D warnings.
