AI Summary

Fixes phantom LD2410 sensor detection and ENOMEM loop issues in ESP32-S3 CSI node firmware.

Key Highlights

  • Fixed phantom LD2410 by requiring full validated report frames (head + tail)
  • Changed ENOMEM backoff from fixed 100ms to exponential (100→2000ms)

Full 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.
