+/// Sorting logic (in priority order):
+/// 1. Matching networks always ranked before non-matching networks
+/// 2. For matching networks: Priority first (CRITICAL - tracks failure history)
+/// 3. RSSI as tiebreaker for equal priority or non-matching networks
+///
+/// WHY PRIORITY MUST BE CHECKED FIRST:
+/// The priority field tracks connection failure history via priority degradation:
+/// - Initial priority: 0.0 (from config or default)
+/// - Each connection failure: priority -= 1.0 (becomes -1.0, -2.0, -3.0, etc.)
+/// - Failed BSSIDs sorted lower → naturally try different BSSID on next scan
+///
+/// This enables automatic BSSID cycling for various real-world failure scenarios:
+/// - Crashed/hung AP (visible but not responding)
+/// - Misconfigured mesh node (accepts auth but no DHCP/routing)
+/// - Capacity limits (AP refuses new clients)
+/// - Rogue AP (same SSID, wrong password or malicious)
+/// - Intermittent hardware issues (flaky radio, overheating)
+///
+/// Example mesh network: 3 APs with same SSID "home", all at priority 0.0 initially
+/// - Try strongest BSSID A (sorted by RSSI) → fails → priority A becomes -1.0
+/// - Next scan: BSSID B and C (priority 0.0) sorted BEFORE A (priority -1.0)
+/// - Try next strongest BSSID B → succeeds or fails and gets deprioritized
+/// - System naturally cycles through all BSSIDs via priority degradation
+/// - Eventually finds working AP or tries all options before restarting adapter
+///
+/// If we checked RSSI first (Bug in PR #9963):
+/// - Same failed BSSID would keep being selected if it has strongest signal
+/// - Device stuck connecting to crashed AP with -30dBm while working AP at -50dBm ignored
