- Phase 2 (Observation): passive client mapping from data frame headers, ClientInfo array per slot (up to 8 clients), 5s observation window - Phase 3 (Targeting): unicast deauth burst to each discovered client instead of broadcast, reason code 7, 5 frames per client - Phase 4 (Capture): timeout + retry loop cycles back to observation to refresh stale client list (2 cycles within 30s channel timeout) - Fix EAPOL detection: compute LLC/SNAP offset from QoS vs non-QoS header length, verify AA-AA-03 SNAP prefix, skip protected frames - Concurrency: portMUX spinlock for callback/main-loop shared state, no dynamic alloc in callback, pre-allocated 4KB PCAP buffer per slot - Phase-aware LCD status display (mapping → capturing → EAPOL count) Made-with: Cursor
