#1170 — live multistatic bridge fed raw, un-canonicalized per-node CSI (64/128/192 bins) to MultistaticFuser, tripping DimensionMismatch every cycle and silently disabling fusion on mixed HT20/HT40 meshes. Add HardwareNormalizer::resample_to_canonical (resample-only, no z-score) and canonicalize every node frame onto the 56-tone grid before fusion. #1180 — update_csi_fps_ema only rejected dt<=0 or >=1s, so sub-ms UDP-burst arrivals (36us -> ~27kHz) inflated csi_fps_ema 40-840x. Add a 5ms plausibility floor and stop re-anchoring observe_csi_frame_arrival on burst deltas. #1183 — global ENOMEM backoff (CSI flood) starved <=48B/<=1Hz control packets. Add stream_sender_send_priority() bypassing the backoff gate without touching the streak; route feature_state/HEALTH/sync through it. Fix the misleading "HEALTH sent" log that printed even on rv_mesh_send failure. Verified: signal 501, sensing-server 677 tests (0 failed); firmware builds clean.
