ESP32-S3 CSI node firmware v0.8.3-esp32 — bug-fix release.

Fixed

  • #1170 — multistatic fusion DimensionMismatch flood. The live sensing-server bridge fed raw, un-canonicalized per-node CSI (HT20≈64 / HT40≈128/192 bins) into MultistaticFuser, so fusion errored every cycle on a mixed mesh and silently fell back to per-node sum/dedup. Node frames are now resampled onto the canonical 56-tone grid (resample-only, no z-score) before fusion.
  • #1180 — csi_fps_ema inflated 40–840×. Sub-millisecond UDP burst arrivals (36 µs → ~27 kHz) polluted the per-node frame-rate EMA. A 5 ms plausibility floor now rejects burst deltas, and the arrival anchor is kept across bursts so the next genuine gap measures true cadence.
  • #1183 — ENOMEM backoff starved control packets. Under a weak uplink the global CSI backoff also suppressed the ≤48 B/≤1 Hz feature_state/HEALTH/sync packets. A new priority send path bypasses the backoff gate (without touching the streak) for those control packets; the misleading "HEALTH sent" log now reports the real send result.

Tooling

  • Added scripts/firmware-release-guard.sh (#1194): regenerates the expected partition table from the variant's CSV and byte-compares it to the built partition-table.bin (+ flash-size cross-check), failing closed so a release can't ship a partition table that doesn't match its flash-size variant.

Verification (MEASURED)

  • wifi-densepose-signal: 501 passed, 0 failed
  • wifi-densepose-sensing-server: 677 passed, 0 failed
  • Firmware: both variants build clean (ESP-IDF v5.4); release guard PASS for 8MB (partitions_display.csv) and 4MB (partitions_4mb.csv).
  • ✅ Hardware smoke test PASS — flashed the 8MB build to an ESP32-S3 (QFN56 rev v0.2, the #1116 board); booted clean, streamed real WiFi CSI (mixed len=128/len=384, RSSI −42…−59), emitted HEALTH/feature_state via the #1183 priority path, mesh time-sync fail=0, and no #1116 edge_dsp watchdog crash over the capture. Note: #1183 starvation needs a weak (~−78 dBm) uplink to trigger; strong-RSSI bench run shows no regression but does not reproduce that specific condition.
