ADR-110 P9 — software-only unblocks for the WITNESS-LOG-110 §B
hardware-blocked items. Two new modules, both default-off so v0.6.6 fleets
see no behavior change.
LP-core (B4 path):
- New firmware/esp32-csi-node/main/lp_core/main.c: real RISC-V LP-core
motion-gate program with debounce + monotonic motion_count counter.
- c6_lp_core.c rewritten to load + run the LP binary via ulp_lp_core_run
when CONFIG_C6_LP_CORE_ENABLE=y; falls back to the v0.6.6 ext1 GPIO-wake
path otherwise (keeps regression surface small).
- ulp_embed_binary() wired in main/CMakeLists.txt, gated on the Kconfig.
- New Kconfig knobs: C6_LP_POLL_PERIOD_US (default 10 ms),
C6_LP_DEBOUNCE_SAMPLES (default 3).
- Exposes c6_lp_core_motion_count() / c6_lp_core_poll_count() for the
witness harness — once an INA/Joulescope is on the bench, B4 is one
capture away from a measured number.
Soft-AP HE (B1/B2 unblock):
- New c6_softap_he.{h,c}: brings up the C6 in AP+STA mode with WPA2-PSK
+ HE advertisement, so a second C6 in STA mode can negotiate real
iTWT against a known-cooperative AP without buying an 11ax router.
- main.c calls c6_softap_he_start() right before esp_wifi_start() when
CONFIG_C6_SOFTAP_HE_ENABLE=y.
- New Kconfig knobs: C6_SOFTAP_HE_{SSID,PSK,CHANNEL} with NVS overrides
via softap_ssid / softap_psk / softap_chan in the ruview namespace.
Build artifacts (IDF v5.4, both green, RC=0):
- S3 8 MB: 1093 KB (47% partition slack)
- C6 4 MB: 1019 KB (45% partition slack)
- SHA-256 sums in dist/firmware-v0.6.7/SHA256SUMS.txt
Doc updates: CHANGELOG wave-3 entry, ADR-110 phase table gets P5
upgrade note + new P9 row, WITNESS-LOG-110 gets new A0 section
recording the v0.6.7 build evidence.

/**

* @file c6_softap_he.h

|
* @brief ESP32-C6 soft-AP with Wi-Fi 6 (HE) capability + TWT Responder.
|
|
*
|
|
* ADR-110 §B1/B2 cheap-unblock: turn one C6 board into the iTWT-capable
|
|
* AP that the C6-DevKit-on-the-shelf-only bench is missing. A second C6
|
|
* board in STA mode can then negotiate a real iTWT agreement against
|
|
* this AP and measure deterministic CSI cadence — without buying an
|
|
* 11ax router.
|
|
*
|
|
* Build-gated by CONFIG_C6_SOFTAP_HE_ENABLE (default n). When disabled,
|
|
* all functions become no-ops so non-AP firmwares pay zero overhead.
|
|
*
|
|
* NVS overrides (read at boot if present, fall back to Kconfig defaults):
|
|
* softap_ssid (string, up to 32 chars)
|
|
* softap_psk (string, 8..63 chars)
|
|
* softap_chan (u8, 1..13)
