+## [v0.5.3-esp32] — 2026-03-30
+
+### Added
+- **Cross-node RSSI-weighted feature fusion** — Multiple ESP32 nodes fuse CSI features using RSSI-based weighting. Closer node gets higher weight. Reduces variance noise by 29%, keypoint jitter by 72%.
+- **DynamicMinCut person separation** — Uses `ruvector_mincut::DynamicMinCut` on the subcarrier temporal correlation graph to detect independent motion clusters. Replaces variance-based heuristic for multi-person counting.
+- **RSSI-based position tracking** — Skeleton position driven by RSSI differential between nodes. Walk between ESP32s and the skeleton follows you.
+- **Per-node state pipeline (ADR-068)** — Each ESP32 node gets independent `HashMap<u8, NodeState>` with frame history, classification, vitals, and person count. Fixes #249 (the #1 user-reported issue).
+- **RuVector Phase 1-3 integration** — Subcarrier importance weighting, temporal keypoint smoothing (EMA), coherence gating, skeleton kinematic constraints (Jakobsen relaxation), compressed pose history.
+- **Client-side lerp smoothing** — UI keypoints interpolate between frames (alpha=0.15) for fluid skeleton movement.
+- **Multi-node mesh tests** — 8 integration tests covering 1-255 node configurations.
+- **`wifi_densepose` Python package** — `from wifi_densepose import WiFiDensePose` now works (#314).
+
+### Fixed
+- **Watchdog crash on busy LANs (#321)** — Batch-limited edge_dsp to 4 frames before 20ms yield. Fixed idle-path busy-spin (`pdMS_TO_TICKS(5)==0`).
+- **No detection from edge vitals (#323)** — Server now generates `sensing_update` from Tier 2+ vitals packets.
+- **RSSI byte offset mismatch (#332)** — Server parsed RSSI from wrong byte (was reading sequence counter).
+- **Stack overflow risk** — Moved 4KB of BPM scratch buffers from stack to static storage.
+- **Stale node memory leak** — `node_states` HashMap evicts nodes inactive >60s.
+- **Unsafe raw pointer removed** — Replaced with safe `.clone()` for adaptive model borrow.
+- **Firmware CI** — Upgraded to IDF v5.4, replaced `xxd` with `od` (#327).
+- **Person count double-counting** — Multi-node aggregation changed from `sum` to `max`.
+- **Skeleton jitter** — Removed tick-based noise, dampened procedural animation, recalibrated feature scaling for real ESP32 data.
+
+### Changed
+- Motion-responsive skeleton: arm swing (0-80px) driven by CSI variance, leg kick (0-50px) by motion_band_power, vertical bob when walking.
+- Person count thresholds recalibrated for real ESP32 hardware (1→2 at 0.70, EMA alpha 0.04).
+- Vital sign filtering: larger median window (31), faster EMA (0.05), looser HR jump filter (15 BPM).
+- Vendored ruvector updated to v2.1.0-40 (316 commits ahead).
+
+### Benchmarks (2-node mesh, COM6 + COM9, 30s)
+| Metric | Baseline | v0.5.3 | Improvement |
+|--------|----------|--------|-------------|
+| Variance noise | 109.4 | 77.6 | **-29%** |
+| Feature stability | std=154.1 | std=105.4 | **-32%** |
+| Keypoint jitter | std=4.5px | std=1.3px | **-72%** |
+| Confidence | 0.643 | 0.686 | **+7%** |
+| Presence accuracy | 93.4% | 94.6% | **+1.3pp** |
+
+### Verified
+- Real hardware: COM6 (node 1) + COM9 (node 2) on ruv.net WiFi
+- All 284 Rust tests pass, 352 signal crate tests pass
+- Firmware builds clean at 843 KB
+- QEMU CI: 11/11 jobs green
