Features: - Introduce a Backend trait + System impl so flow/status/watch can be unit tested against a fake; add 11 connect-state-machine tests. - Captive-portal detection: status::connectivity returns Online/Portal/Offline; surfaced in status, JSON, connect notes, and a dedicated watch state. - `status --json` for bars/scripts; `profile add`/`profile remove`; detect now scores by number of in-range markers. Robustness: - Pin LC_ALL=C/LANG=C on child processes for locale-independent parsing. - Atomic config/state writes (temp + rename); 0600 config never world-readable. - Transient PSK file written to $XDG_RUNTIME_DIR when available. Fixes (from prior audit): - Feed Wi-Fi PSK to nmcli via stdin/passwd-file, never argv. - mask() no longer panics on multi-byte passwords. - Connectivity check requires HTTP 204 (no captive-portal false positives). - nmcli NAME,TYPE parsing handles escaped colons. - Strip CIDR suffix from displayed IP; PKGBUILD/Cargo version aligned (2.1.0).

//! The seam between breadcrumbs' decision logic and the outside world.
|
|
//!
|
|
//! Every interaction with NetworkManager, Tailscale, connectivity probes,
|
|
//! notifications and logging goes through the [`Backend`] trait. Production code
|
|
//! uses [`System`], which delegates to the `nm`/`tailscale`/`status`/`notify`
|
|
//! modules that shell out. Tests inject a fake so the connect state machine
|
|
//! (`flow`) and watch classifier can be exercised without touching the host.
