+# ADR-060: Provision Channel Override and MAC Address Filtering
+
+- **Status:** Accepted
+- **Date:** 2026-03-12
+- **Issues:** [#247](https://github.com/ruvnet/RuView/issues/247), [#229](https://github.com/ruvnet/RuView/issues/229)
+
+## Context
+
+Two related provisioning gaps were reported by users:
+
+1. **Channel mismatch (Issue #247):** The CSI collector initializes on the
+   Kconfig default channel (typically 6), even when the ESP32 connects to an AP
+   on a different channel (e.g. 11). On managed networks where the user cannot
+   change the router channel, this makes nodes undiscoverable. The
+   `provision.py` script has no `--channel` argument.
+
+2. **Missing MAC filter (Issue #229):** The v0.2.0 release notes documented a
+   `--filter-mac` argument for `provision.py`, but it was never implemented.
+   The firmware's CSI callback accepts frames from all sources, causing signal
+   mixing in multi-AP environments.
+
+## Decision
+
+### Channel configuration
+
+- Add `--channel` argument to `provision.py` that writes a `csi_channel` key
+  (u8) to NVS.
+- In `nvs_config.c`, read the `csi_channel` key and override
+  `channel_list[0]` when present.
+- In `csi_collector_init()`, after WiFi connects, auto-detect the AP channel
+  via `esp_wifi_sta_get_ap_info()` and use it as the default CSI channel when
+  no NVS override is set. This ensures the CSI collector always matches the
+  connected AP's channel without requiring manual provisioning.
+
+### MAC address filtering
+
+- Add `--filter-mac` argument to `provision.py` that writes a `filter_mac`
+  key (6-byte blob) to NVS.
+- In `nvs_config.h`, add a `filter_mac[6]` field and `filter_mac_set` flag.
+- In `nvs_config.c`, read the `filter_mac` blob from NVS.
+- In the CSI callback (`wifi_csi_callback`), if `filter_mac_set` is true,
+  compare the source MAC from the received frame against the configured MAC
+  and drop non-matching frames.
+
+### Provisioning flow
+
+```
+python provision.py --port COM7 --channel 11
+python provision.py --port COM7 --filter-mac "AA:BB:CC:DD:EE:FF"
+python provision.py --port COM7 --channel 11 --filter-mac "AA:BB:CC:DD:EE:FF"
+```
+
+## Consequences
+
+- Users on managed networks can force the CSI channel to match their AP
+- Multi-AP environments can filter CSI to a single source
+- Auto-channel detection eliminates the most common misconfiguration
+- Backward compatible: existing provisioned nodes without these keys behave
+  as before (use Kconfig default channel, accept all MACs)

+
+## Context
+
+The ESP32-S3 CSI node firmware (`firmware/esp32-csi-node/`) has grown to 16 source files spanning:
+
+| Module | File | Testable in QEMU? |
+|--------|------|--------------------|
+| NVS config load | `nvs_config.c` | Yes — NVS partition in flash image |
+| Edge processing (DSP) | `edge_processing.c` | Yes — all math, no HW dependency |
+| ADR-018 frame serialization | `csi_collector.c:csi_serialize_frame()` | Yes — pure buffer ops |
+| UDP stream sender | `stream_sender.c` | Yes — QEMU has lwIP via SLIRP |
+| WASM runtime | `wasm_runtime.c` | Yes — CPU only |
+| OTA update | `ota_update.c` | Partial — needs HTTP mock |
+| Power management | `power_mgmt.c` | Partial — no real light-sleep |
+| Display (OLED) | `display_*.c` | No — I2C hardware |
+| WiFi CSI callback | `csi_collector.c:wifi_csi_callback()` | **No** — requires RF PHY |
+| Channel hopping | `csi_collector.c:hop_timer_cb()` | **No** — requires `esp_wifi_set_channel()` |
+
+Currently, **every code change requires flashing to physical hardware** on COM7. This creates a bottleneck:
+- Build + flash cycle: ~20 seconds
+- Serial monitor: manual inspection
+- No automated CI (no ESP32-S3 in GitHub Actions runners)
+- Contributors without hardware cannot test firmware changes
+
+Espressif maintains an official QEMU fork (`github.com/espressif/qemu`) with ESP32-S3 machine support, including dual-core Xtensa LX7, flash mapping, UART, GPIO, timers, and FreeRTOS.
+
+## Decision
+
+Introduce a **comprehensive QEMU testing platform** for the ESP32-S3 CSI node firmware with nine capability layers:
+
+1. **Mock CSI generator** — compile-time synthetic CSI frame injection
+2. **QEMU runner** — automated build, run, and validation
+3. **Multi-node mesh simulation** — TDM and aggregation testing across QEMU instances
+4. **GDB remote debugging** — zero-cost breakpoint debugging without JTAG
+5. **Code coverage** — gcov/lcov integration for path analysis
+6. **Fuzz testing** — malformed input resilience for CSI parser, NVS, WASM
+7. **NVS provisioning matrix** — exhaustive config combination testing
+8. **Snapshot & replay** — sub-100ms state restore for fast iteration
+9. **Chaos testing** — fault injection for resilience validation

+
+### Mock CSI Generator Design
+
+When `CONFIG_CSI_MOCK_ENABLED=y` (Kconfig option), the build replaces `esp_wifi_set_csi_config()` / `esp_wifi_set_csi_rx_cb()` with a periodic timer that injects synthetic CSI frames:
+
+```c
+// mock_csi.c — synthetic CSI frame generator
+
+#define MOCK_CSI_INTERVAL_MS   50   // 20 Hz (matches real CSI rate)
+#define MOCK_N_SUBCARRIERS     52   // HT20 mode
+#define MOCK_IQ_LEN            (MOCK_N_SUBCARRIERS * 2)  // I + Q bytes
+
+typedef struct {
+    uint8_t  scenario;        // 0=empty, 1=person_static, 2=person_walking, 3=fall
+    uint32_t frame_count;
+    float    person_x;        // Simulated position [0..1]
+    float    person_speed;    // Movement speed per frame
+    uint8_t  breathing_phase; // Simulated breathing cycle
+} mock_state_t;
+
+// Generates realistic CSI I/Q data:
+// - Empty room: Gaussian noise + stable phase (low variance)
+// - Static person: Phase shift proportional to distance, breathing modulation
+// - Walking person: Progressive phase drift + Doppler-like amplitude change
+// - Fall event: Sudden phase acceleration spike
+void mock_generate_csi_frame(mock_state_t *state, wifi_csi_info_t *out_info);
+```
+
+### Signal Model
+
+The synthetic CSI generator models subcarrier amplitude and phase as:
+
+```
+A_k(t) = A_base + A_person * exp(-d_k²/σ²) + noise
+φ_k(t) = φ_base + (2π * d / λ) + breathing_mod(t) + noise
+
+where:
+  k         = subcarrier index
+  d_k       = simulated distance effect on subcarrier k
+  A_person  = amplitude perturbation from human body (scenario-dependent)
+  d         = simulated person-to-antenna distance
+  λ         = wavelength at subcarrier frequency
+  breathing_mod(t) = sin(2π * f_breath * t) * amplitude_breath
+  noise     = Gaussian, σ tuned to match real ESP32-S3 CSI noise floor (~-90 dBm)
+```
+
+This model exercises:
+- Presence detection (amplitude variance exceeds threshold)
+- Breathing rate extraction (periodic phase modulation at 0.1-0.5 Hz)
+- Fall detection (sudden phase acceleration exceeding `fall_thresh`)
+- Multi-person separation (distinct subcarrier groups with different breathing frequencies)
+
+### Scenarios
+
+| ID | Scenario | Duration | Expected Output |
+|----|----------|----------|-----------------|
+| 0 | Empty room | 10s | `presence=0`, `motion_energy < thresh` |
+| 1 | Static person | 10s | `presence=1`, `breathing_rate ∈ [10,25]`, `fall=0` |
+| 2 | Walking person | 10s | `presence=1`, `motion_energy > 0.5`, `fall=0` |
+| 3 | Fall event | 5s | `fall=1` flag set, `motion_energy` spike |
+| 4 | Multi-person | 15s | `n_persons=2`, independent breathing rates |
+| 5 | Channel sweep | 5s | Frames on channels 1, 6, 11 in sequence |
+| 6 | MAC filter test | 5s | Frames with wrong MAC are dropped (counter check) |
+| 7 | Ring buffer overflow | 3s | 1000 frames in 100ms burst, graceful drop |
+| 8 | Boundary RSSI | 5s | RSSI sweeps -127 to 0, no crash |
+| 9 | Zero-length frame | 2s | `iq_len=0` frames, serialize returns 0 |

+### Mesh Validation Checks
+
+| Check | Pass Criteria |
+|-------|---------------|
+| All nodes booted | N distinct `node_id` values in received frames |
+| TDM ordering | Slot 0 frames arrive before slot 1 within each TDM cycle |
+| No slot collision | No two frames from different nodes with overlapping timestamps within TDM window |
+| Frame count balance | Each node contributes ±10% of total frames |
+| ADR-018 compliance | All frames have valid magic `0xC5110001` and correct node IDs |
+| Vitals per node | Each node produces independent vitals packets |

+## Layer 4: GDB Remote Debugging
+
+QEMU provides a built-in GDB stub for zero-cost debugging without JTAG hardware.
+
+### Usage
+
+```bash
+# Launch QEMU with GDB stub (paused at boot)
+qemu-system-xtensa \
+  -machine esp32s3 \
+  -nographic \
+  -drive file=build/qemu_flash.bin,if=mtd,format=raw \
+  -serial mon:stdio \
+  -s -S   # -s = GDB on :1234, -S = pause at start
+
+# In another terminal: attach GDB
+xtensa-esp-elf-gdb build/esp32-csi-node.elf \
+  -ex "target remote :1234" \
+  -ex "b edge_processing.c:dsp_task" \
+  -ex "b csi_collector.c:wifi_csi_callback" \
+  -ex "b mock_csi.c:mock_generate_csi_frame" \
+  -ex "watch g_nvs_config.csi_channel" \
+  -ex "continue"
+```

+
+## Layer 6: Fuzz Testing
+
+### Fuzz Targets
+
+| Target | Input | Mutation Strategy | Looking For |
+|--------|-------|-------------------|-------------|
+| `csi_serialize_frame()` | Random `wifi_csi_info_t` | Extreme `len` (0, 65535), NULL `buf`, negative RSSI, channel 255 | Buffer overflow, NULL deref |
+| `nvs_config_load()` | Crafted NVS partition binary | Truncated strings, out-of-range u8/u16, missing keys, corrupt headers | Kconfig fallback, no crash |
+| `edge_enqueue_csi()` | Rapid-fire 10,000 frames | Vary `iq_len` (0 to `EDGE_MAX_IQ_BYTES+1`), randomize RSSI | Ring overflow, no data corruption |
+| `rvf_parser.c` | Malformed RVF network packets | Bad magic, truncated headers, oversized payloads | Parse rejection, no crash |
+| `wasm_upload.c` | Corrupt WASM blobs | Invalid magic, oversized modules, bad Ed25519 signatures, truncated | Rejection without crash, no code execution |
+| `csi_serialize_frame()` + `edge_enqueue_csi()` | Chained: generate → serialize → enqueue | End-to-end with random data | Pipeline integrity |
+
+### Implementation Approach
+
+```c
+// test/fuzz_csi_serialize.c — runs on host (not ESP32)
+// Compiled with: clang -fsanitize=fuzzer,address
+
+#include "csi_collector.h"
+
+int LLVMFuzzerTestOneInput(const uint8_t *data, size_t size) {
+    if (size < sizeof(wifi_csi_info_t)) return 0;
+
+    wifi_csi_info_t info;
+    memcpy(&info, data, sizeof(info));
+
+    // Point buf at remaining fuzz data
+    size_t remaining = size - sizeof(info);
+    uint8_t iq_buf[2048];
+    if (remaining > sizeof(iq_buf)) remaining = sizeof(iq_buf);
+    memcpy(iq_buf, data + sizeof(info), remaining);
+    info.buf = iq_buf;
+    info.len = (int)remaining;
+
+    uint8_t out[4096];
+    csi_serialize_frame(&info, out, sizeof(out));
+    return 0;
+}
+```

+## Layer 7: NVS Provisioning Matrix
+
+### Config Combinations
+
+| Config | NVS Values | Validates |
+|--------|-----------|-----------|
+| `default` | (empty NVS) | Kconfig fallback paths |
+| `wifi-only` | ssid, password | Basic provisioning |
+| `full-adr060` | channel=6, filter_mac=AA:BB:CC:DD:EE:FF | Channel override + MAC filter |
+| `edge-tier0` | edge_tier=0 | Raw CSI passthrough (no DSP) |
+| `edge-tier1` | edge_tier=1, pres_thresh=100, fall_thresh=2000 | Stats-only mode |
+| `edge-tier2-custom` | edge_tier=2, vital_win=128, vital_int=500, subk_count=16 | Full vitals with custom params |
+| `tdm-3node` | tdm_slot=1, tdm_nodes=3, node_id=1 | TDM mesh timing |
+| `wasm-signed` | wasm_max=4, wasm_verify=1, wasm_pubkey=<32 bytes> | WASM with Ed25519 verification |
+| `wasm-unsigned` | wasm_max=2, wasm_verify=0 | WASM without signature check |
+| `5ghz-channel` | channel=36, filter_mac=... | 5 GHz CSI collection |
+| `boundary-max` | target_port=65535, node_id=255, top_k=32, vital_win=256 | Max-range values |
+| `boundary-min` | target_port=1, node_id=0, top_k=1, vital_win=32 | Min-range values |
+| `power-save` | power_duty=10, edge_tier=0 | Low-power mode |
+| `corrupt-nvs` | (manually crafted partial/corrupt partition) | Graceful fallback to defaults |
+
+### Automated Matrix Generation
+
+```python
+# scripts/generate_nvs_matrix.py
+# Generates all 14 NVS partition binaries for CI matrix
+
+CONFIGS = [
+    {"name": "default", "args": []},
+    {"name": "wifi-only", "args": ["--ssid", "Test", "--password", "test1234"]},
+    {"name": "full-adr060", "args": ["--channel", "6", "--filter-mac", "AA:BB:CC:DD:EE:FF",
+                                      "--ssid", "Test", "--password", "test"]},
+    {"name": "edge-tier0", "args": ["--edge-tier", "0"]},
+    # ... all 14 configs
+]
+```
+
+---
+
+## Layer 8: Snapshot & Replay
+
+### QEMU Snapshot Commands
+
+```bash
+# Save snapshot after boot + NVS load (skip 3s boot time)
+(qemu) savevm post_boot
+
+# Save after WiFi connect + first CSI frame
+(qemu) savevm post_connect
+
+# Save after edge pipeline calibration complete (~60s)
+(qemu) savevm post_calibration
+
+# Restore any snapshot (< 100ms)
+(qemu) loadvm post_connect
+```
+
+### Automated Snapshot Pipeline
+
+```bash
+# scripts/qemu-snapshot-test.sh
+
+# Phase 1: Create base snapshots (one-time, cached in CI)
+qemu-system-xtensa ... -monitor unix:qemu.sock,server,nowait &
+sleep 5
+echo "savevm post_boot" | socat - UNIX-CONNECT:qemu.sock
+sleep 10
+echo "savevm post_first_frame" | socat - UNIX-CONNECT:qemu.sock
+
+# Phase 2: Run quick tests from snapshots (< 1s each)
+for test in test_presence test_fall test_multi_person; do
+  echo "loadvm post_first_frame" | socat - UNIX-CONNECT:qemu.sock
+  echo "cont" | socat - UNIX-CONNECT:qemu.sock
+  sleep 2  # Run test scenario
+  # Validate output
+done
+```
+
+### Performance Impact
+
+| Operation | Without Snapshots | With Snapshots |
+|-----------|-------------------|----------------|
+| Full boot + NVS + WiFi mock | ~5 seconds | ~5 seconds (first run) |
+| Run single scenario | ~5s boot + ~5s test = 10s | ~0.1s restore + ~5s test = 5.1s |
+| Run all 10 scenarios | ~100 seconds | ~51 seconds (49% faster) |
+| Run 14 NVS configs × 10 scenarios | ~23 minutes | ~12 minutes (48% faster) |
+
+---
+
+## Layer 9: Chaos Testing
+
+### Fault Injection Table
+
+| Fault | Injection Method | Expected Behavior | Severity |
+|-------|-----------------|-------------------|----------|
+| WiFi disconnect | Timer kills mock WiFi connection after N frames | Reconnect attempt, CSI pauses and resumes | HIGH |
+| Ring buffer overflow | Burst 1000 frames in 100ms | Frame drop counter increments, no crash, no data corruption | HIGH |
+| NVS corruption | Flash image with partial-write NVS partition | Falls back to Kconfig defaults, logs warning | MEDIUM |
+| Stack overflow | Deep recursion in WASM module callback | Watchdog fires, task restarts, no hang | HIGH |
+| Heap exhaustion | `malloc` returns NULL after N allocations | Graceful degradation, logs OOM, continues operation | HIGH |
+| Timer starvation | Block DSP task for 500ms | Frames dropped from ring, no deadlock, recovers | MEDIUM |
+| UDP send failure | SLIRP network down | `stream_sender_send` returns -1, error counter increments | LOW |
+| Corrupt CSI frame | Inject frame with invalid magic in I/Q data | Edge pipeline rejects, increments error counter | LOW |
+| NVS write during read | Concurrent NVS open for write while config loads | No corruption, NVS handle isolation | MEDIUM |
+
+### Chaos Runner
+
+```bash
+# scripts/qemu-chaos-test.sh
+
+# Run with fault injection enabled
+qemu-system-xtensa ... \
+  -monitor unix:qemu.sock,server,nowait &
+
+# Inject faults via GDB or monitor commands
+for fault in wifi_kill heap_exhaust ring_flood; do
+  echo "[CHAOS] Injecting: $fault"
+  python3 scripts/inject_fault.py --socket qemu.sock --fault "$fault"
+  sleep 5
+  python3 scripts/check_health.py --log "$LOG_FILE" --after-fault "$fault"
+done
+```

+
+## Consequences
+
+### Benefits
+
+1. **No hardware required** — contributors validate firmware changes with QEMU alone
+2. **Automated CI** — every PR touching `firmware/` runs 14 NVS configs × 10 scenarios in parallel
+3. **10× faster iteration** — snapshot restore in <100ms vs 20s flash cycle
+4. **Security hardening** — fuzz testing catches buffer overflows, NULL derefs, and parser bugs before they reach hardware
+5. **Mesh validation** — multi-node TDM tested without 3 physical ESP32s
+6. **Coverage visibility** — lcov reports show untested edge processing paths
+7. **Resilience proof** — chaos tests verify firmware recovers from WiFi drops, OOM, and ring overflow
+8. **GDB debugging** — set breakpoints on DSP pipeline without JTAG adapter
+9. **Regression detection** — boot failures, NVS parsing errors, and FreeRTOS deadlocks caught in CI
+
+### Limitations
+
+1. **No real WiFi/CSI** — QEMU cannot emulate the ESP32-S3 WiFi radio or CSI extraction hardware
+2. **Synthetic CSI fidelity** — mock frames approximate real CSI patterns but don't capture real-world multipath, interference, or antenna characteristics
+3. **Timing differences** — QEMU timing is not cycle-accurate; FreeRTOS tick rates may differ from hardware
+4. **No peripheral testing** — I2C display, real GPIO, and light-sleep power management cannot be tested
+5. **QEMU build requirement** — Espressif's QEMU fork must be built from source (not in Ubuntu packages)
+6. **Coverage overhead** — gcov-enabled builds are ~2× slower in QEMU
+
+### What QEMU Testing Covers vs Requires Hardware
+
+| Test Domain | QEMU | Hardware |
+|-------------|------|----------|
+| Boot + NVS config (14 configs) | Full | Full |
+| Edge DSP pipeline (biquad, Welford, top-K) | Full | Full |
+| ADR-018 frame serialization | Full | Full |
+| Vitals packet generation (0xC5110002) | Full | Full |
+| WASM module loading + execution | Full | Full |
+| Multi-node TDM mesh (3+ nodes) | Full (TAP) | Full |
+| Fuzz testing (CSI parser, NVS) | Full | N/A |
+| Code coverage analysis | Full | Partial |
+| GDB breakpoint debugging | Full | Full (JTAG) |
+| Chaos/fault injection | Full | Manual |
+| OTA update flow | Partial (HTTP mock) | Full |
+| Real WiFi connection | No | Full |
+| Real CSI data quality | No | Full |
+| Channel hopping on RF | No | Full |
+| MAC filter on real frames | No | Full |
+| Power management (light-sleep) | No | Full |
+| Display rendering (OLED) | No | Full |
+| UDP over real network | No | Full |
+
+---
+
+## Alternatives Considered
+
+### 1. Host-native unit tests (no QEMU)
+Extract pure C functions (`csi_serialize_frame`, edge DSP math) and compile/test on host with CMock/Unity. Simpler but doesn't test FreeRTOS integration, NVS, or boot sequence.
+
+**Verdict**: Complementary — do both. Host unit tests for math, QEMU for integration. Fuzz targets (Layer 6) already use host-native compilation.
+
+### 2. Hardware-in-the-loop CI (real ESP32 on runner)
+Use a self-hosted GitHub Actions runner with a physical ESP32-S3 attached.
+
+**Verdict**: Valuable but expensive and fragile. QEMU covers ~85% of test cases (up from 70% with all 9 layers). Add HIL later for real CSI validation only.
+
+### 3. Docker-based ESP-IDF build only (no runtime test)
+Just verify the firmware compiles in CI without running it.
+
+**Verdict**: Already possible but insufficient — compilation doesn't catch runtime bugs (stack overflow, NVS parsing errors, FreeRTOS deadlocks).
+
+### 4. Renode emulator
+Alternative to QEMU with better peripheral modeling for some platforms.
+
+**Verdict**: Renode has ESP32 support but ESP32-S3 support is less mature than Espressif's own QEMU fork. Revisit if Renode adds full S3 support.

+# ruvector-attention-wasm
+
+WebAssembly bindings for the ruvector-attention package, providing high-performance attention mechanisms for browser and Node.js environments.
+
+## Features
+
+- **Multiple Attention Mechanisms**:
+  - Scaled Dot-Product Attention
+  - Multi-Head Attention
+  - Hyperbolic Attention (for hierarchical data)
+  - Linear Attention (Performer-style)
+  - Flash Attention (memory-efficient)
+  - Local-Global Attention
+  - Mixture of Experts (MoE) Attention
+  - **CGT Sheaf Attention** (coherence-gated via Prime-Radiant)
+
+- **Training Utilities**:
+  - InfoNCE contrastive loss
+  - Adam optimizer
+  - AdamW optimizer (with decoupled weight decay)
+  - Learning rate scheduler (warmup + cosine decay)
+
+- **TypeScript Support**: Full type definitions and modern API
+
+## Installation
+
+```bash
+npm install ruvector-attention-wasm
+```
+
+## Usage
+
+### TypeScript/JavaScript
+
+```typescript
+import { initialize, MultiHeadAttention, utils } from 'ruvector-attention-wasm';
+
+// Initialize WASM module
+await initialize();
+
+// Create multi-head attention
+const attention = new MultiHeadAttention({ dim: 64, numHeads: 8 });
+
+// Prepare inputs
+const query = new Float32Array(64);
+const keys = [new Float32Array(64), new Float32Array(64)];
+const values = [new Float32Array(64), new Float32Array(64)];
+
+// Compute attention
+const output = attention.compute(query, keys, values);
+
+// Use utilities
+const similarity = utils.cosineSimilarity(query, keys[0]);
+```
+
+### Advanced Examples
+
+#### Hyperbolic Attention
+
+```typescript
+import { HyperbolicAttention } from 'ruvector-attention-wasm';
+
+const hyperbolic = new HyperbolicAttention({
+  dim: 128,
+  curvature: 1.0
+});
+
+const output = hyperbolic.compute(query, keys, values);
+```
+
+#### MoE Attention with Expert Stats
+
+```typescript
+import { MoEAttention } from 'ruvector-attention-wasm';
+
+const moe = new MoEAttention({
+  dim: 64,
+  numExperts: 4,
+  topK: 2
+});
+
+const output = moe.compute(query, keys, values);
+
+// Get expert utilization
+const stats = moe.getExpertStats();
+console.log('Load balance:', stats.loadBalance);
+```
+
+#### Training with InfoNCE Loss
+
+```typescript
+import { InfoNCELoss, Adam } from 'ruvector-attention-wasm';
+
+const loss = new InfoNCELoss(0.07);
+const optimizer = new Adam(paramCount, {
+  learningRate: 0.001,
+  beta1: 0.9,
+  beta2: 0.999,
+});
+
+// Training loop
+const lossValue = loss.compute(anchor, positive, negatives);
+optimizer.step(params, gradients);
+```
+
+#### Learning Rate Scheduling
+
+```typescript
+import { LRScheduler, AdamW } from 'ruvector-attention-wasm';
+
+const scheduler = new LRScheduler({
+  initialLR: 0.001,
+  warmupSteps: 1000,
+  totalSteps: 10000,
+});
+
+const optimizer = new AdamW(paramCount, {
+  learningRate: scheduler.getLR(),
+  weightDecay: 0.01,
+});
+
+// Training loop
+for (let step = 0; step < 10000; step++) {
+  optimizer.learningRate = scheduler.getLR();
+  optimizer.step(params, gradients);
+  scheduler.step();
+}
+```
+

+
+## API Reference
+
+### Attention Mechanisms
+
+- `MultiHeadAttention` - Standard multi-head attention
+- `HyperbolicAttention` - Attention in hyperbolic space
+- `LinearAttention` - Linear complexity attention (Performer)
+- `FlashAttention` - Memory-efficient attention
+- `LocalGlobalAttention` - Combined local and global attention
+- `MoEAttention` - Mixture of Experts attention
+- `CGTSheafAttention` - Coherence-gated via Prime-Radiant energy
+- `scaledDotAttention()` - Functional API for basic attention
+
+### CGT Sheaf Attention (Prime-Radiant Integration)
+
+The CGT (Coherence-Gated Transformer) Sheaf Attention mechanism uses Prime-Radiant's sheaf Laplacian energy to gate attention based on mathematical consistency:
+
+```typescript
+import { CGTSheafAttention } from 'ruvector-attention-wasm';
+
+const cgtAttention = new CGTSheafAttention({
+  dim: 128,
+  numHeads: 8,
+  coherenceThreshold: 0.3,  // Block if energy > threshold
+});
+
+// Attention is gated by coherence energy
+const result = cgtAttention.compute(query, keys, values);
+console.log('Coherence energy:', result.energy);
+console.log('Is coherent:', result.isCoherent);
+```
+
+**Key features:**
+- Energy-weighted attention: Lower coherence energy → higher attention
+- Automatic hallucination detection via residual analysis
+- GPU-accelerated with wgpu WGSL shaders (vec4 optimized)
+- SIMD fallback (AVX-512/AVX2/NEON)
+
+### Training
+
+- `InfoNCELoss` - Contrastive loss function
+- `Adam` - Adam optimizer
+- `AdamW` - AdamW optimizer with weight decay
+- `LRScheduler` - Learning rate scheduler
+
+### Utilities
+
+- `utils.cosineSimilarity()` - Cosine similarity between vectors
+- `utils.l2Norm()` - L2 norm of a vector
+- `utils.normalize()` - Normalize vector to unit length
+- `utils.softmax()` - Apply softmax transformation
+- `utils.attentionWeights()` - Compute attention weights from scores
+- `utils.batchNormalize()` - Batch normalization
+- `utils.randomOrthogonalMatrix()` - Generate random orthogonal matrix
+- `utils.pairwiseDistances()` - Compute pairwise distances
+
+## Performance
+
+The WASM bindings provide near-native performance for attention computations:
+
+- Optimized with `opt-level = "s"` and LTO
+- SIMD acceleration where available
+- Efficient memory management
+- Zero-copy data transfer where possible

Includes pre-built WASM package (~52KB) for browser deployment. - ADR-058: Dual-modal architecture design - ui/pose-fusion.html: Main demo page with dark theme UI - 7 JS modules: video-capture, csi-simulator, cnn-embedder, fusion-engine, pose-decoder, canvas-renderer, main orchestrator - Pre-built ruvector-cnn-wasm WASM package for browser - CSI heatmap, embedding space visualization, latency metrics - WebSocket support for live ESP32 CSI data - Navigation link added to main dashboard Co-Authored-By: claude-flow <ruv@ruv.net> * fix: motion-responsive skeleton + through-wall CSI tracking - Pose decoder now uses per-cell motion grid to track actual arm/head positions — raising arms moves the skeleton's arms, head follows lateral movement - Motion grid (10x8 cells) tracks intensity per body zone: head, left/right arm upper/mid, legs - Through-wall mode: when person exits frame, CSI maintains presence with slow decay (~10s) and skeleton drifts in exit direction - CSI simulator persists sensing after video loss, ghost pose renders with decreasing confidence - Reduced temporal smoothing (0.45) for faster response to movement Co-Authored-By: claude-flow <ruv@ruv.net> * fix: video fills available space + correct WASM path resolution - Remove fixed aspect-ratio and max-height from video panel so it fills the available viewport space without scrolling - Grid uses 1fr row for content area, overflow:hidden on main grid - Fix WASM path: resolve relative to JS module file using import.meta.url instead of hardcoded ./pkg/ which resolved incorrectly on gh-pages - Responsive: mobile still gets aspect-ratio constraint Co-Authored-By: claude-flow <ruv@ruv.net> * feat: live ESP32 CSI pipeline + auto-connect WebSocket - Add auto-connect to local sensing server WebSocket (ws://localhost:8765) - Demo shows "Live ESP32" when connected to real CSI data - Add build_firmware.ps1 for native Windows ESP-IDF builds (no Docker) - Add read_serial.ps1 for ESP32 serial monitor Pipeline: ESP32 → UDP:5005 → sensing-server → WS:8765 → browser demo Co-Authored-By: claude-flow <ruv@ruv.net> * docs: add ADR-059 live ESP32 CSI pipeline + update README with demo links - ADR-059: Documents end-to-end ESP32 → sensing server → browser pipeline - README: Add dual-modal pose fusion demo link, update ADR count to 49 - References issue #245 Co-Authored-By: claude-flow <ruv@ruv.net> * feat: RSSI visualization, RuVector attention WASM, cache-bust fixes - Add animated RSSI Signal Strength panel with sparkline history - Fix RuVector WasmMultiHeadAttention retptr calling convention - Wire up RuVector Multi-Head + Flash Attention in CNN embedder - Add ambient temporal drift to CSI simulator for visible heatmap animation - Fix embedding space projection (sparse projection replaces cancelling sum) - Add auto-scaling to embedding space renderer - Add cache busters (?v=4) to all ES module imports to prevent stale caches - Add diagnostic logging for module version verification - Add RSSI tracking with quality labels and color-coded dBm display - Includes ruvector-attention-wasm v2.0.5 browser ESM wrapper Co-Authored-By: claude-flow <ruv@ruv.net> * feat: 26-keypoint dexterous pose + full RuVector attention pipeline Pose Decoder (17 → 26 keypoints): - Add finger approximations: thumb, index, pinky per hand (6 new) - Add toe tips: left/right foot index (2 new) - Add neck keypoint (1 new) - Hand openness driven by arm motion intensity - Finger positions computed from wrist-elbow axis angles CNN Embedder (full RuVector WASM pipeline): - Stage 1: Multi-Head Attention (global spatial reasoning) - Stage 2: Hyperbolic Attention (hierarchical body-part tree) - Stage 3: MoE Attention (3 experts: upper/lower/extremities, top-2) - Blended 40/30/30 weighting → final embedding projection Canvas Renderer: - Magenta finger joints with distinct glow - Cyan toe tips - White neck keypoint - Thinner limb lines for hand/foot connections - Joint count shown in overlay label CSI Simulator: - Skip synthetic person state when live ESP32 connected - Only simulate CSI data in demo mode (was already correct) Embedding Space: - Fixed projection: sparse 8-dim projection replaces cancelling sum - Auto-scaling normalizes point spread to fill canvas Cache busters bumped to v=5 on all imports. Co-Authored-By: claude-flow <ruv@ruv.net> * fix: centroid-based pose tracking for responsive limb movement Rewrites pose decoder from intensity-based to position-based tracking: - Arms now track toward motion centroid in each body zone - Elbow/wrist positions computed along shoulder→centroid vector - Legs track toward lower-body zone centroids - Smoothing reduced from 0.45 to 0.25 for responsiveness - Zone centroids blend 30% old / 70% new each frame 6 body zones with overlapping coverage: - Head (top 20%, center cols) - Left/Right Arm (rows 10-60%, outer cols) - Torso (rows 15-55%, center cols) - Left/Right Leg (rows 50-100%, half cols each) Hand openness now driven by arm spread distance + raise amount. Cache busters v=6. Co-Authored-By: claude-flow <ruv@ruv.net> * fix: remove duplicate lAnkleX/rAnkleX declarations in pose-decoder Stale code block from old intensity-based tracking was left behind, re-declaring variables already defined by centroid-based tracking. Co-Authored-By: claude-flow <ruv@ruv.net> * feat(demo): wire all 6 RuVector WASM attention mechanisms into pose fusion - Add WasmLinearAttention and WasmLocalGlobalAttention to browser ESM wrapper - Add 6 WASM utility functions (batch_normalize, pairwise_distances, etc.) - Extend CnnEmbedder to 6-stage pipeline: Flash → MHA → Hyperbolic → Linear → MoE → L+G - Use log-energy softmax blending across all 6 stages - Wire WASM cosine_similarity and normalize into FusionEngine - Add RuVector pipeline stats panel to UI (energy, refinement, pose impact) - Compute embedding-to-joint mapping stats without modifying joint positions - Center camera prompt with flexbox layout - Add cache busters v=12 Co-Authored-By: claude-flow <ruv@ruv.net>	2026-03-12 20:59:57 -04:00
