+Verified 2026-08-23 (read-only, W1N-207): add-on `started`, version `9.0.4`, no
+update pending; current GUA `240e:3bd:238:4812:*` (PD rotated again since 08-22)
+advertised correctly over v4+v6. Both ESP32-C2 bulbs now announce `_matter._tcp`
+(multi-fabric, including this host's fabric `DCE86145C137AF0E`) — but they
+**refuse TCP 5540 on IPv4 and IPv6**, so matter-server holds **zero established
+:5540 sessions** (device-side failure mode C; no errors logged — see
+[docs/matter-pairing-troubleshoot.md §8](../docs/matter-pairing-troubleshoot.md)).
