release notes

ESP32-S3 CSI node firmware — fixes the #1135 phantom-LD2410 + sendto ENOMEM loop reported against v0.8.1-esp32.

Fixes (#1135)

Phantom LD2410 on a floating UART (root cause). Probe-detection matched only the 4-byte head 0xF4F3F2F1, so line noise at 256000 baud on an unconnected UART1 could phantom-detect a sensor and spawn a UART task. Now requires a full validated report frame (head + sane intra-frame length + matching tail 0xF8F7F6F5) — the same validate-before-trust gate used for MR60BHA2 in v0.8.1. Extracted to mmwave_detect.h and covered by a host unit test (test_mmwave_detect.c).
sendto ENOMEM stuck loop. The fixed 100 ms backoff was too short to drain sustained lwIP/WiFi buffer pressure. Now exponential (100→200→…→2000 ms per consecutive ENOMEM, reset on first successful send). Removing the phantom LD2410 task also removes the extra load that tipped tier-2 nodes into the stuck state.

Validation

All CI green (firmware s3-8mb/4mb + c6, all QEMU configs, fuzzing, security scans).
Host unit test: the #1135 case (head magic without valid tail) is REJECTED.
Hardware (ESP32-S3 QFN56 rev v0.2): streams clean at tier-0 and tier-2, correctly reports no mmWave (no phantom), no regression.
Caveat: the reporter's environment-specific floating-pin noise could not be reproduced on the bench, so the deterministic proof for the phantom case is the unit test. If you hit #1135, please confirm this build clears it.
