Firmware built with acquire-everything CSI (L-LTF + HT-LTF + STBC HT-LTF,
per csi_collector.c) streams 0xC5110001 frames with 192 complex values.
parse_csi_packet passed them through whole, so every frame failed the HT20
tier geometry check ('expected 52, got 192') and calibrate/enroll/room-watch
could never capture a baseline on such nodes (refs ruvnet#1000).
Slice the HT-LTF segment [64..128) out of 192-subcarrier frames so the
64-FFT HT20 tier configs line up. Hardware-validated on a bare
ESP32-S3-N16R8 (display-less build from main): full ADR-151
baseline -> enroll -> train-room -> room-watch pipeline ran end-to-end.

Summary
Fixes the CLI half of #1000:
calibrate/enroll/room-watchrejected every raw CSI frame from firmware built with the current acquire-everything CSI config, making the ADR-151 per-room calibration pipeline unusable on such nodes.Root cause
csi_collector.c(S3 branch) enableslltf_en + htltf_en + stbc_htltf2_en, so the0xC5110001raw frames carry 192 complex values (L-LTF + HT-LTF + STBC HT-LTF, 64 each —CSI cb: len=384in the boot log).parse_csi_packetpassed the frame through whole, and the HT20 tier geometry check rejected it:Fix
When a frame reports 192 subcarriers, slice the HT-LTF segment (
[64..128)) before building theCsiFrame, so the 64-FFT HT20 tier config (52 active) lines up. Frames with other geometries are untouched.Validation

All 19 crate tests pass (cargo test -p wifi-densepose-cli --no-default-features).main@2a307138,edge_tier=0, ~33 Hz raw stream): the full ADR-151 pipeline ran end-to-end — 600-frame baseline (52 active subcarriers), guided enrollment (5/8 anchors),train-room(6 specialists), and liveroom-watchcorrectly reportingabsentfor an empty room and sustainedpresent / posture=lyingwith plausible breathing (11.8 bpm) for a person near the node.Notes
