fix(firmware): edge_dsp task watchdog starvation on Core 1 (#266)

process_frame() is CPU-intensive (biquad filters, Welford stats,
BPM estimation, multi-person vitals) and can run for several ms.
At priority 5, edge_dsp starves IDLE1 (priority 0) on Core 1,
triggering the task watchdog every 5 seconds.

Fix: vTaskDelay(1) after every frame to let IDLE1 reset the
watchdog. At 20 Hz CSI rate this adds ~1 ms per frame —
negligible for vitals extraction.

Verified on real ESP32-S3 with live WiFi CSI: 0 watchdog
triggers in 60 seconds (was triggering every 5s before fix).

+## [v0.4.3-esp32] — 2026-03-15
+
+### Fixed
+- **Fall detection false positives (#263)** — Default threshold raised from 2.0 to 15.0 rad/s²; normal walking (2-5 rad/s²) no longer triggers alerts. Added 3-consecutive-frame debounce and 5-second cooldown between alerts. Verified on real ESP32-S3 hardware: 0 false alerts in 60s / 1,300+ live WiFi CSI frames.
+- **Kconfig default mismatch** — `CONFIG_EDGE_FALL_THRESH` Kconfig default was still 2000 (=2.0) while `nvs_config.c` fallback was updated to 15.0. Fixed Kconfig to 15000. Caught by real hardware testing — mock data did not reproduce.
+- **provision.py NVS generator API change** — `esp_idf_nvs_partition_gen` package changed its `generate()` signature; switched to subprocess-first invocation for cross-version compatibility.
+- **QEMU CI pipeline (11 jobs)** — Fixed all failures: fuzz test `esp_timer` stubs, QEMU `libgcrypt` dependency, NVS matrix generator, IDF container `pip` path, flash image padding, validation WARN handling, swarm `ip`/`cargo` missing.
+
+### Added
+- **4MB flash support (#265)** — `partitions_4mb.csv` and `sdkconfig.defaults.4mb` for ESP32-S3 boards with 4MB flash (e.g. SuperMini). Dual OTA slots, 1.856 MB each. Thanks to @sebbu for the community workaround that confirmed feasibility.
+- **`--strict` flag** for `validate_qemu_output.py` — WARNs now pass by default in CI (no real WiFi in QEMU); use `--strict` to fail on warnings.
+
 ## [Unreleased]
 
 ### Added
+- **QEMU ESP32-S3 testing platform (ADR-061)** — 9-layer firmware testing without hardware
+  - Mock CSI generator with 10 physics-based scenarios (empty room, walking, fall, multi-person, etc.)
+  - Single-node QEMU runner with 16-check UART validation
+  - Multi-node TDM mesh simulation (TAP networking, 2-6 nodes)
+  - GDB remote debugging with VS Code integration
+  - Code coverage via gcov/lcov + apptrace
+  - Fuzz testing (3 libFuzzer targets + ASAN/UBSAN)
+  - NVS provisioning matrix (14 configs)
+  - Snapshot-based regression testing (sub-second VM restore)
+  - Chaos testing with fault injection + health monitoring
+- **QEMU Swarm Configurator (ADR-062)** — YAML-driven multi-ESP32 test orchestration
+  - 4 topologies: star, mesh, line, ring
+  - 3 node roles: sensor, coordinator, gateway
+  - 9 swarm-level assertions (boot, crashes, TDM, frame rate, fall detection, etc.)
+  - 7 presets: smoke (2n/15s), standard (3n/60s), ci-matrix, large-mesh, line-relay, ring-fault, heterogeneous
+  - Health oracle with cross-node validation
+- **QEMU installer** (`install-qemu.sh`) — auto-detects OS, installs deps, builds Espressif QEMU fork
+- **Unified QEMU CLI** (`qemu-cli.sh`) — single entry point for all 11 QEMU test commands
+- CI: `firmware-qemu.yml` workflow with QEMU test matrix, fuzz testing, NVS validation, and swarm test jobs
+- User guide: QEMU testing and swarm configurator section with plain-language walkthrough
+
+### Fixed
+- Firmware now boots in QEMU: WiFi/UDP/OTA/display guards for mock CSI mode
+- 9 bugs in mock_csi.c (LFSR bias, MAC filter init, scenario loop, overflow burst timing)
+- 23 bugs from ADR-061 deep review (inject_fault.py writes, CI cache, snapshot log corruption, etc.)
+- 16 bugs from ADR-062 deep review (log filename mismatch, SLIRP port collision, heap false positives, etc.)
+- All scripts: `--help` flags, prerequisite checks with install hints, standardized exit codes
+
 - **Sensing server UI API completion (ADR-043)** — 14 fully-functional REST endpoints for model management, CSI recording, and training control
   - Model CRUD: `GET /api/v1/models`, `GET /api/v1/models/active`, `POST /api/v1/models/load`, `POST /api/v1/models/unload`, `DELETE /api/v1/models/:id`, `GET /api/v1/models/lora/profiles`, `POST /api/v1/models/lora/activate`

+<summary><strong>QEMU Firmware Testing (ADR-061) — 9-Layer Platform</strong></summary>
+
+Test ESP32-S3 firmware without physical hardware using Espressif's QEMU fork. The platform provides 9 layers of testing capability:
+
+| Layer | Capability | Script / Config |
+|-------|-----------|-----------------|
+| 1 | Mock CSI generator (10 physics-based scenarios) | `firmware/esp32-csi-node/main/mock_csi.c` |
+| 2 | Single-node QEMU runner + UART validation (16 checks) | `scripts/qemu-esp32s3-test.sh`, `scripts/validate_qemu_output.py` |
+| 3 | Multi-node TDM mesh simulation (TAP networking) | `scripts/qemu-mesh-test.sh`, `scripts/validate_mesh_test.py` |
+| 4 | GDB remote debugging (VS Code integration) | `.vscode/launch.json` |
+| 5 | Code coverage (gcov/lcov via apptrace) | `firmware/esp32-csi-node/sdkconfig.coverage` |
+| 6 | Fuzz testing (libFuzzer + ASAN/UBSAN) | `firmware/esp32-csi-node/test/fuzz_*.c` |
+| 7 | NVS provisioning matrix (14 configs) | `scripts/generate_nvs_matrix.py` |
+| 8 | Snapshot regression (sub-second VM restore) | `scripts/qemu-snapshot-test.sh` |
+| 9 | Chaos testing (fault injection + health monitoring) | `scripts/qemu-chaos-test.sh`, `scripts/inject_fault.py`, `scripts/check_health.py` |
+
+```bash
+# Quick start: build + run + validate
+cd firmware/esp32-csi-node
+idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.qemu" build
+
+# Single-node test (builds, merges flash, runs QEMU, validates output)
+bash scripts/qemu-esp32s3-test.sh
+
+# Multi-node mesh test (3 QEMU instances with TDM)
+sudo bash scripts/qemu-mesh-test.sh 3
+
+# Fuzz testing (60 seconds per target)
+cd firmware/esp32-csi-node/test && make all CC=clang && make run_serialize FUZZ_DURATION=60
+
+# Chaos testing (fault injection resilience)
+bash scripts/qemu-chaos-test.sh --faults all --duration 120
+```
+
+**10 test scenarios**: empty room, static person, walking, fall, multi-person, channel sweep, MAC filter, ring overflow, boundary RSSI, zero-length frames.
+
+**14 NVS configs**: default, WiFi-only, full ADR-060, edge tiers 0/1/2, TDM mesh, WASM signed/unsigned, 5GHz, boundary max/min, power-save, empty-strings.
+
+**CI**: GitHub Actions workflow runs 7 NVS matrix configs, 3 fuzz targets, and NVS binary validation on every push to `firmware/`.
+
+See [ADR-061](docs/adr/ADR-061-qemu-esp32s3-firmware-testing.md) for the full architecture.
+

+
+<details>
+<summary><strong>QEMU Swarm Configurator (ADR-062)</strong></summary>
+
+Test multiple ESP32-S3 nodes simultaneously using a YAML-driven orchestrator. Define node roles, network topologies, and validation assertions in a config file.
+
+```bash
+# Quick smoke test (2 nodes, 15 seconds)
+python3 scripts/qemu_swarm.py --preset smoke
+
+# Standard 3-node test (coordinator + 2 sensors)
+python3 scripts/qemu_swarm.py --preset standard
+
+# See all presets
+python3 scripts/qemu_swarm.py --list-presets
+
+# Preview without running
+python3 scripts/qemu_swarm.py --preset standard --dry-run
+```
+
+**Topologies**: star (sensors → coordinator), mesh (fully connected), line (relay chain), ring (circular).
+
+**Node roles**: sensor (generates CSI), coordinator (aggregates), gateway (bridges to host).
+
+**7 presets**: smoke, standard, ci-matrix, large-mesh, line-relay, ring-fault, heterogeneous.
+
+**9 swarm assertions**: boot check, crash detection, TDM collision, frame production, coordinator reception, fall detection, frame rate, boot time, heap health.
+
+See [ADR-062](docs/adr/ADR-062-qemu-swarm-configurator.md) and the [User Guide](docs/user-guide.md#testing-firmware-without-hardware-qemu) for step-by-step instructions.

+# ADR-054: RuView Desktop Full Implementation
+
+## Status
+**Accepted** — Implementation in progress
+
+## Context
+
+RuView Desktop v0.3.0 shipped with a complete React/TypeScript frontend but stub-only Rust backend commands. Users report:
+- Settings cannot be saved (#206) ✅ Fixed in PR #209
+- Flash firmware does nothing
+- OTA updates are non-functional
+- Node discovery returns hardcoded data
+- Server start/stop is cosmetic only
+
+This ADR defines the complete implementation plan to make all desktop features production-ready with proper security, optimization, and error handling.
+
+## Decision
+
+Implement all 14 Tauri commands with full functionality, security hardening, and performance optimization.

+        success: true,
+        message: "Provisioning complete".into(),
+    })
+}
+```
+
+---
+
+## 3. Security Hardening
+
+### 3.1 Input Validation
+
+```rust
+// All string inputs sanitized
+fn validate_ip(ip: &str) -> Result<IpAddr, String> {
+    ip.parse::<IpAddr>().map_err(|_| "Invalid IP address".into())
+}
+
+fn validate_port(port: u16) -> Result<(), String> {
+    if port < 1024 && port != 0 {
+        return Err("Privileged ports (1-1023) not allowed".into());
+    }
+    Ok(())
+}
+
+fn validate_path(path: &str) -> Result<PathBuf, String> {
+    let path = PathBuf::from(path);
+    if path.components().any(|c| c == std::path::Component::ParentDir) {
+        return Err("Path traversal detected".into());
+    }
+    Ok(path)
+}
+```
+
+### 3.2 Network Security
+
+```rust
+// OTA PSK validation
+fn validate_psk(psk: &str) -> Result<(), String> {
+    if psk.len() < 16 {
+        return Err("PSK must be at least 16 characters".into());
+    }
+    if !psk.chars().all(|c| c.is_ascii_alphanumeric() || c == '-' || c == '_') {
+        return Err("PSK contains invalid characters".into());
+    }
+    Ok(())
+}
+
+// Rate limiting for network operations
+struct RateLimiter {
+    last_request: Instant,
+    min_interval: Duration,
+}
+
+impl RateLimiter {
+    fn check(&mut self) -> Result<(), String> {
+        if self.last_request.elapsed() < self.min_interval {
+            return Err("Rate limit exceeded".into());
+        }
+        self.last_request = Instant::now();
+        Ok(())
+    }
+}
+```
+
+### 3.3 Binary Validation
+
+```rust
+fn validate_esp_binary(data: &[u8]) -> Result<(), String> {
+    // Check ESP binary magic (0xE9 at offset 0)
+    if data.is_empty() || data[0] != 0xE9 {
+        return Err("Invalid ESP firmware magic byte".into());
+    }
+
+    // Check minimum size (header + some code)
+    if data.len() < 256 {
+        return Err("Firmware too small".into());
+    }
+
+    // Check maximum size (4MB flash)
+    if data.len() > 4 * 1024 * 1024 {
+        return Err("Firmware exceeds flash size".into());
+    }
+
+    Ok(())
+}
+```
+
+---
+
+## 4. Performance Optimization
+
+### 4.1 Async Everything
+
+All I/O operations are async with proper timeouts:
+
+```rust
+// Timeout wrapper
+async fn with_timeout<T, F: Future<Output = Result<T, String>>>(
+    future: F,
+    duration: Duration,
+) -> Result<T, String> {
+    tokio::time::timeout(duration, future)
+        .await
+        .map_err(|_| "Operation timed out".into())?
+}
+```
+
+### 4.2 Connection Pooling
+
+```rust
+// Reusable HTTP client
+lazy_static! {
+    static ref HTTP_CLIENT: reqwest::Client = reqwest::Client::builder()
+        .pool_max_idle_per_host(5)
+        .pool_idle_timeout(Duration::from_secs(30))
+        .build()
+        .unwrap();
+}
+```
+
+### 4.3 Streaming Progress
+
+Flash and OTA operations stream progress via Tauri events:
+
+```rust
+// Real-time progress updates
+app.emit("flash_progress", FlashProgress { ... })?;
+app.emit("ota_progress", OtaProgress { ... })?;
+```
+
+---
+
+## 5. Testing Strategy
+
+### 5.1 Unit Tests
+
+```rust
+#[cfg(test)]
+mod tests {
+    #[test]
+    fn test_validate_ip() {
+        assert!(validate_ip("192.168.1.1").is_ok());
+        assert!(validate_ip("invalid").is_err());
+    }
+
+    #[test]
+    fn test_validate_esp_binary() {
+        let valid = vec![0xE9; 1024];
+        assert!(validate_esp_binary(&valid).is_ok());
+
+        let invalid = vec![0x00; 1024];
+        assert!(validate_esp_binary(&invalid).is_err());
+    }
+}
+```
+
+### 5.2 Integration Tests
+
+```rust
+#[tokio::test]
+async fn test_discover_nodes_timeout() {
+    let result = discover_nodes(Some(100)).await;
+    assert!(result.is_ok());
+    // Should return empty or cached results within timeout
+}
+```
+
+### 5.3 Mock Testing
+
+```rust
+// Mock serial port for flash tests
+struct MockSerial {
+    responses: VecDeque<Vec<u8>>,
+}
+
+impl Read for MockSerial { ... }
+impl Write for MockSerial { ... }
+```
+
+---
+
+## 6. Dependencies Update
+
+**Cargo.toml additions:**
+```toml
+[dependencies]
+# Discovery
+mdns-sd = "0.11"
+serialport = "4.6"
+
+# HTTP client

+# ADR-055: Integrated Sensing Server in Desktop App
+
+## Status
+Accepted
+
+## Context
+The RuView Desktop application (ADR-054) requires the WiFi sensing server to provide real-time CSI data, activity detection, and vital signs monitoring. Currently, the sensing server is a separate binary (`wifi-densepose-sensing-server`) that must be installed separately and found in the system PATH.
+
+This creates several problems:
+1. **Distribution complexity**: Users must install two binaries
+2. **Path issues**: Binary may not be in PATH, causing "No such file or directory" errors
+3. **Version mismatch**: Server and desktop app versions may diverge
+4. **Poor UX**: Error messages about missing binaries confuse users
+
+## Decision
+Bundle the sensing server binary inside the desktop application and provide intelligent binary discovery with clear fallback paths.
+
+### Binary Discovery Order
+The desktop app searches for the sensing server in this order:
+1. **Custom path** from user settings (`server_path`)
+2. **Bundled resources** (`Contents/Resources/bin/` on macOS)
+3. **Next to executable** (same directory as the app binary)
+4. **System PATH** (legacy fallback)
+
+### Implementation
+```rust
+fn find_server_binary(app: &AppHandle, custom_path: Option<&str>) -> Result<String, String> {
+    // 1. Custom path from settings
+    if let Some(path) = custom_path {
+        if std::path::Path::new(path).exists() {
+            return Ok(path.to_string());
+        }
+    }
+
+    // 2. Bundled in resources
+    if let Ok(resource_dir) = app.path().resource_dir() {
+        let bundled = resource_dir.join("bin").join(DEFAULT_SERVER_BIN);
+        if bundled.exists() {
+            return Ok(bundled.to_string_lossy().to_string());
+        }
+    }
+
+    // 3. Next to executable
+    if let Ok(exe_path) = std::env::current_exe() {
+        if let Some(exe_dir) = exe_path.parent() {
+            let sibling = exe_dir.join(DEFAULT_SERVER_BIN);
+            if sibling.exists() {
+                return Ok(sibling.to_string_lossy().to_string());
+            }
+        }
+    }
+
+    // 4. System PATH
+    // ... which lookup ...
+
+    Err("Sensing server binary not found")
+}
+```
+
+### Bundle Configuration
+In `tauri.conf.json`:
+```json
+{
+  "bundle": {
+    "resources": [
+      {
+        "src": "../../target/release/wifi-densepose-sensing-server",
+        "target": "bin/wifi-densepose-sensing-server"
+      }
+    ]
+  }
+}
+```
+
+## Consequences
+
+### Positive
+- **Single package distribution**: Users download one DMG/MSI/EXE
+- **Version alignment**: Server and UI always match
+- **Better UX**: No PATH configuration required
+- **Offline capable**: Works without network access to download server
+
+### Negative
+- **Larger bundle size**: ~10-15MB additional for server binary
+- **Build complexity**: Must build server before bundling desktop
+- **Platform-specific**: Need separate server binaries per platform
+
+### Neutral
+- CI/CD workflow updated to build server before desktop
+- GitHub Actions builds all platforms (macOS arm64/x64, Windows x64)
+
+## WebSocket Integration
+The Sensing page connects to the bundled server's WebSocket endpoint:
+- `ws://127.0.0.1:{ws_port}/ws/sensing` - Real-time CSI data stream
+- `ws://127.0.0.1:{ws_port}/ws/pose` - Pose estimation stream
+
+Message format:
+```typescript
+interface WsSensingUpdate {
+  type: string;
+  timestamp: number;
+  source: string;
+  tick: number;
+  nodes: WsNodeInfo[];
+  classification: { motion_level: string; presence: boolean; confidence: number };
+  vital_signs?: { breathing_rate_hz?: number; heart_rate_bpm?: number };
+}
+```
+
+## Security Considerations
+- Server binary signed with same certificate as desktop app
+- Communication over localhost only (127.0.0.1)
+- No external network access by default
+- Process spawned as child of desktop app (inherits permissions)

+

+| **Issues**  | #223, #238, #234, #210, #190                |
+
+## Context
+
+Multiple GitHub issues (#223, #238, #234, #210, #190) report firmware problems
+that fall into two categories:
+
+1. **CSI not enabled at runtime** — The committed `sdkconfig` had
+   `# CONFIG_ESP_WIFI_CSI_ENABLED is not set` (line 1135), meaning users who
+   built from source or used pre-built binaries got the runtime error:
+   `E (6700) wifi:CSI not enabled in menuconfig!`
+
+   Root cause: `sdkconfig.defaults.template` existed with the correct setting
+   (`CONFIG_ESP_WIFI_CSI_ENABLED=y`) but ESP-IDF only reads
+   `sdkconfig.defaults` — not `.template` suffixed files. No `sdkconfig.defaults`
+   file was committed.
+
+2. **Unsupported ESP32 variants** — Users attempting to use original ESP32
+   (D0WD) and ESP32-C3 boards. The firmware targets ESP32-S3 only
+   (`CONFIG_IDF_TARGET="esp32s3"`, Xtensa architecture) and this was not
+   surfaced clearly enough in documentation or build errors.
+
+## Decision
+
+### Fix 1: Commit `sdkconfig.defaults` (not just template)
+
+Copy `sdkconfig.defaults.template` → `sdkconfig.defaults` so that ESP-IDF
+applies the correct defaults (including `CONFIG_ESP_WIFI_CSI_ENABLED=y`)
+automatically when `sdkconfig` is regenerated.
+
+### Fix 2: `#error` compile-time guard in `csi_collector.c`
+
+Add a preprocessor guard:
+
+```c
+#ifndef CONFIG_ESP_WIFI_CSI_ENABLED
+#error "CONFIG_ESP_WIFI_CSI_ENABLED must be set in sdkconfig."
+#endif
+```
+
+This turns a confusing runtime crash into a clear compile-time error with
+instructions on how to fix it.
+
+### Fix 3: Fix committed `sdkconfig`
+
+Change line 1135 from `# CONFIG_ESP_WIFI_CSI_ENABLED is not set` to
+`CONFIG_ESP_WIFI_CSI_ENABLED=y`.
+
+## Consequences
+
+- **Positive**: New builds will always have CSI enabled. Users building from
+  source will get a clear compile error if CSI is somehow disabled.
+- **Positive**: Pre-built release binaries will include CSI support.
+- **Neutral**: Original ESP32 and ESP32-C3 remain unsupported. This is by
+  design — only ESP32-S3 has the CSI API surface we depend on. Future ADRs
+  may address multi-target support if demand warrants it.
+- **Negative**: None identified.
+
+## Hardware Support Matrix
+
+| Variant      | CSI Support | Firmware Target | Status        |
+|--------------|-------------|-----------------|---------------|
+| ESP32-S3     | Yes         | Yes             | Supported     |
+| ESP32 (orig) | Partial     | No              | Unsupported   |
+| ESP32-C3     | Yes (IDF 5.1+) | No           | Unsupported   |
+| ESP32-C6     | Yes         | No              | Unsupported   |
+
+## Notes

+# ADR-058: Dual-Modal WASM Browser Pose Estimation — Live Video + WiFi CSI Fusion
+
+- **Status**: Proposed
+- **Date**: 2026-03-12
+- **Deciders**: ruv
+- **Tags**: wasm, browser, cnn, pose-estimation, ruvector, video, multimodal, fusion
+
+## Context
+
+WiFi-DensePose estimates human poses from WiFi CSI (Channel State Information).
+The `ruvector-cnn` crate provides a pure Rust CNN (MobileNet-V3) with WASM bindings.
+Both modalities exist independently — what's missing is **fusing live webcam video
+with WiFi CSI** in a single browser demo to achieve robust pose estimation that
+works even when one modality degrades (occlusion, signal noise, poor lighting).
+
+Existing assets:
+
+1. **`wifi-densepose-wasm`** — CSI signal processing compiled to WASM
+2. **`wifi-densepose-sensing-server`** — Axum server streaming live CSI via WebSocket
+3. **`ruvector-cnn`** — Pure Rust CNN with MobileNet-V3 backbones, SIMD, contrastive learning
+4. **`ruvector-cnn-wasm`** — wasm-bindgen bindings: `WasmCnnEmbedder`, `SimdOps`, `LayerOps`, contrastive losses
+5. **`vendor/ruvector/examples/wasm-vanilla/`** — Reference vanilla JS WASM example
+
+Research shows multi-modal fusion (camera + WiFi) significantly outperforms either alone:
+- Camera fails under occlusion, poor lighting, privacy constraints
+- WiFi CSI fails with signal noise, multipath, low spatial resolution
+- Fusion compensates: WiFi provides through-wall coverage, camera provides fine-grained detail
+
+## Decision
+
+Build a **dual-modal browser demo** at `examples/wasm-browser-pose/` that:
+
+1. Captures **live webcam video** via `getUserMedia` API
+2. Receives **live WiFi CSI** via WebSocket from the sensing server
+3. Processes **both streams** through separate CNN pipelines in `ruvector-cnn-wasm`
+4. **Fuses embeddings** with learned attention weights for combined pose estimation
+5. Renders **video overlay** with skeleton + WiFi confidence heatmap on Canvas
+6. Runs entirely in the browser — all inference client-side via WASM
+

+
+### Dual Pipeline Design
+
+Two parallel CNN pipelines run on each frame tick (~30 FPS):
+
+| Pipeline | Input | Preprocessing | CNN Config | Output |
+|----------|-------|---------------|------------|--------|
+| **Visual** | Webcam frame (640×480) | Resize to 224×224 RGB, ImageNet normalize | MobileNet-V3 Small, 512-dim | Visual embedding |
+| **CSI** | CSI frame (ADR-018 binary) | Amplitude/phase/delta → 224×224 pseudo-RGB | MobileNet-V3 Small, 512-dim | CSI embedding |
+
+Both use the same `WasmCnnEmbedder` but with separate instances and weight sets.
+
+### Fusion Strategy
+
+**Learned attention-weighted fusion** combines the two 512-dim embeddings:
+
+```javascript
+// Attention fusion: learn which modality to trust per-dimension
+// α ∈ [0,1]^512 — attention weights (shipped as JSON, trained offline)
+// visual_emb, csi_emb ∈ R^512
+
+function fuseEmbeddings(visual_emb, csi_emb, attention_weights) {
+    const fused = new Float32Array(512);
+    for (let i = 0; i < 512; i++) {
+        const α = attention_weights[i];
+        fused[i] = α * visual_emb[i] + (1 - α) * csi_emb[i];
+    }
+    return fused;
+}
+```
+
+**Dynamic confidence gating** adjusts fusion based on signal quality:
+
+| Condition | Behavior |
+|-----------|----------|
+| Good video + good CSI | Balanced fusion (α ≈ 0.5) |
+| Poor lighting / occlusion | CSI-dominant (α → 0, WiFi takes over) |
+| CSI noise / no ESP32 | Video-dominant (α → 1, camera only) |
+| Video-only mode (no WiFi) | α = 1.0, pure visual CNN pose estimation |
+| CSI-only mode (no camera) | α = 0.0, pure WiFi pose estimation |
+
+Quality detection:
+- **Video quality**: Frame brightness variance (dark = low quality), motion blur score
+- **CSI quality**: Signal-to-noise ratio from `wifi-densepose-wasm`, coherence gate output
+
+### CSI-to-Image Encoding
+
+CSI data encoded as 3-channel pseudo-image for the CSI CNN pipeline:
+
+| Channel | Data | Normalization |
+|---------|------|---------------|
+| R | CSI amplitude (subcarrier × time window) | Min-max to [0, 255] |
+| G | CSI phase (unwrapped, subcarrier × time window) | Min-max to [0, 255] |
+| B | Temporal difference (frame-to-frame Δ amplitude) | Abs, min-max to [0, 255] |
+
+### Video Processing
+
+Webcam frames processed through standard ImageNet pipeline:
+
+```javascript
+// Capture frame from video element
+const frame = captureVideoFrame(videoElement, 224, 224); // Returns Uint8Array RGB
+
+// ImageNet normalization happens inside WasmCnnEmbedder.extract()
+const visual_embedding = visual_embedder.extract(frame, 224, 224);
+```
+
+### Pose Keypoint Mapping
+
+17 COCO-format keypoints decoded from the fused 512-dim embedding:
+
+```
+ 0: nose          1: left_eye       2: right_eye
+ 3: left_ear      4: right_ear      5: left_shoulder
+ 6: right_shoulder 7: left_elbow    8: right_elbow
+ 9: left_wrist   10: right_wrist   11: left_hip
+12: right_hip    13: left_knee     14: right_knee
+15: left_ankle   16: right_ankle
+```
+
+Each keypoint decoded as (x, y, confidence) = 51 values from the 512-dim embedding
+via a learned linear projection.
+
+### Operating Modes
+
+The demo supports three modes, selectable in the UI:
+
+| Mode | Video | CSI | Fusion | Use Case |
+|------|-------|-----|--------|----------|
+| **Dual (default)** | ✅ | ✅ | Attention-weighted | Best accuracy, full demo |
+| **Video Only** | ✅ | ❌ | α = 1.0 | No ESP32 available, quick demo |
+| **CSI Only** | ❌ | ✅ | α = 0.0 | Privacy mode, through-wall sensing |
+
+**Video Only mode works without any hardware** — just a webcam — making the demo
+instantly accessible for anyone wanting to try it.

+### WASM Module Structure
+
+| Package | Source Crate | Provides | Size (est.) |
+|---------|-------------|----------|-------------|
+| `wifi_densepose_wasm` | `wifi-densepose-wasm` | CSI frame parsing, signal processing, feature extraction | ~200KB |
+| `ruvector_cnn_wasm` | `ruvector-cnn-wasm` | `WasmCnnEmbedder` (×2 instances), `SimdOps`, `LayerOps`, contrastive losses | ~150KB |
+
+Two `WasmCnnEmbedder` instances are created — one for video frames, one for CSI pseudo-images.
+They share the same WASM module but have independent state.
+
+### Browser API Requirements
+
+| API | Purpose | Required | Fallback |
+|-----|---------|----------|----------|
+| `getUserMedia` | Webcam capture | For video mode | CSI-only mode |
+| WebAssembly | CNN inference | Yes | None (hard requirement) |
+| WASM SIMD128 | Accelerated inference | No | Scalar fallback (~2× slower) |
+| WebSocket | CSI data stream | For CSI mode | Video-only mode |
+| Canvas 2D | Rendering | Yes | None |
+| `requestAnimationFrame` | Render loop | Yes | `setTimeout` fallback |
+| ES Modules | Code organization | Yes | None |
+
+Target: Chrome 89+, Firefox 89+, Safari 15+, Edge 89+
+
+### Performance Budget
+
+| Stage | Target Latency | Notes |
+|-------|---------------|-------|
+| Video frame capture + resize | <3ms | `drawImage` to offscreen canvas |
+| Video CNN embedding | <15ms | 224×224 RGB → 512-dim |
+| CSI receive + parse | <2ms | Binary WebSocket message |
+| CSI pseudo-image encoding | <3ms | Amplitude/phase/delta channels |
+| CSI CNN embedding | <15ms | 224×224 pseudo-RGB → 512-dim |
+| Attention fusion | <1ms | Element-wise weighted sum |
+| Pose decoding | <1ms | Linear projection |
+| Canvas overlay render | <3ms | Video + skeleton + heatmap |
+| **Total (dual mode)** | **<33ms** | **30 FPS capable** |
+| **Total (video only)** | **<22ms** | **45 FPS capable** |
+
+Note: Video and CSI CNN pipelines can run in parallel using Web Workers,
+reducing dual-mode latency to ~max(15, 15) + 5 = ~20ms (50 FPS).
+
+### Contrastive Learning Integration
+
+The demo optionally shows real-time contrastive learning in the browser:
+
+- **InfoNCE loss** (`WasmInfoNCELoss`): Compare video vs CSI embeddings for the same pose — trains cross-modal alignment
+- **Triplet loss** (`WasmTripletLoss`): Push apart different poses, pull together same pose across modalities
+- **SimdOps**: Accelerated dot products for real-time similarity computation
+- **Embedding space panel**: Live 2D projection shows video and CSI embeddings converging when viewing the same person
+
+### Relationship to Existing Crates
+
+| Existing Crate | Role in This Demo |
+|---------------|-------------------|
+| `ruvector-cnn-wasm` | CNN inference for **both** video frames and CSI pseudo-images |
+| `wifi-densepose-wasm` | CSI frame parsing and signal processing |
+| `wifi-densepose-sensing-server` | WebSocket CSI data source |
+| `wifi-densepose-core` | ADR-018 frame format definitions |
+| `ruvector-cnn` | Underlying MobileNet-V3, layers, contrastive learning |
+
+No new Rust crates are needed. The example is pure HTML/JS consuming existing WASM packages.
+
+## Consequences
+
+### Positive
+
+- **Instant demo**: Video-only mode works with just a webcam — no ESP32 needed
+- **Multi-modal showcase**: Demonstrates camera + WiFi fusion, the core innovation of the project
+- **Graceful degradation**: Works with video-only, CSI-only, or both
+- **Through-wall capability**: CSI mode shows pose estimation where cameras cannot reach
+- **Zero-install**: Anyone with a browser can try it
+- **Training data collection**: Can record paired (video, CSI) data for offline model training
+- **Reusable**: JS modules embed directly in the Tauri desktop app's webview
+
+### Negative
+
+- **Model weights**: Requires offline-trained weights for visual CNN, CSI CNN, fusion, and pose decoder (~200KB total JSON)
+- **WASM size**: Two WASM modules total ~350KB (acceptable)
+- **No GPU**: CPU-only WASM inference; adequate at 224×224 but limits resolution scaling
+- **Camera privacy**: Video mode requires camera permission (mitigated: CSI-only mode available)
+- **Two CNN instances**: Memory footprint doubles vs single-modal (~10MB total, acceptable for desktop browsers)
+
+### Risks
+
+- **Cross-modal alignment**: Video and CSI embeddings must be trained jointly for fusion to work;
+  without proper training, fusion may be worse than either modality alone
+- **Latency on mobile**: Dual CNN on mobile browsers may exceed 33ms; implement automatic quality reduction
+- **WebSocket drops**: Network jitter → CSI frame gaps; buffer last 3 frames, interpolate missing data
+
+## Implementation Plan
+
+1. **Phase 1 — Scaffold**: File layout, build.sh, index.html shell, mode selector UI
+2. **Phase 2 — Video pipeline**: getUserMedia → frame capture → CNN embedding → basic pose display
+3. **Phase 3 — CSI pipeline**: WebSocket client → CSI parsing → pseudo-image → CNN embedding
+4. **Phase 4 — Fusion**: Attention-weighted combination, confidence gating, mode switching
+5. **Phase 5 — Pose decoder**: Linear projection with placeholder weights → 17 keypoints
+6. **Phase 6 — Overlay renderer**: Video canvas with skeleton overlay, CSI heatmap panel
+7. **Phase 7 — Training**: Use `wifi-densepose-train` to generate real weights for both CNNs + fusion + decoder
+8. **Phase 8 — Contrastive demo**: Embedding space visualization, cross-modal similarity display
+9. **Phase 9 — Web Workers**: Move CNN inference to workers for parallel video + CSI processing
+10. **Phase 10 — Polish**: Recording, snapshots, adaptive quality, mobile optimization
+
+## Alternatives Considered
+
+### 1. CSI-Only (No Video)
+Rejected: Misses the opportunity to show multi-modal fusion and makes the demo less
+accessible (requires ESP32 hardware). Video-only mode as a fallback is strictly better.
+
+### 2. Server-Side Video Inference
+Rejected: Adds latency, requires webcam stream upload (privacy concern), and defeats
+the WASM-first architecture. All inference must be client-side.
+
+### 3. TensorFlow.js for Video, ruvector-cnn-wasm for CSI
+Rejected: Would require two different ML frameworks. Using `ruvector-cnn-wasm` for both
+keeps a single WASM module, unified embedding space, and simpler fusion.
+
+### 4. Pre-recorded Video Demo
+Rejected: Live webcam input is far more compelling for demonstrations.
+Pre-recorded mode can be added as a secondary option.
+
+### 5. React/Vue Framework
+Rejected: Adds build tooling. Vanilla JS + ES modules keeps the demo self-contained.

+
+## Context
+
+ADR-058 established a dual-modal browser demo combining webcam video and WiFi CSI for pose estimation. However, it used simulated CSI data. To demonstrate real-world capability, we need an end-to-end pipeline from physical ESP32 hardware through to the browser visualization.
+
+The ESP32-S3 firmware (`firmware/esp32-csi-node/`) already supports CSI collection and UDP streaming (ADR-018). The sensing server (`wifi-densepose-sensing-server`) already supports UDP ingestion and WebSocket bridging. The missing piece was connecting these components and enabling the browser demo to consume live data.
+
+## Decision
+
+Implement a complete live CSI pipeline:
+
+```
+ESP32-S3 (CSI capture) → UDP:5005 → sensing-server (Rust/Axum) → WS:8765 → browser demo
+```
+
+### Components
+
+1. **ESP32 Firmware** — Rebuilt with native Windows ESP-IDF v5.4.0 toolchain (no Docker). Configured for target network and PC IP via `sdkconfig`. Helper scripts added:
+   - `build_firmware.ps1` — Sets up IDF environment, cleans, builds, and flashes
+   - `read_serial.ps1` — Serial monitor with DTR/RTS reset capability
+
+2. **Sensing Server** — `wifi-densepose-sensing-server` started with:
+   - `--source esp32` — Expect real ESP32 UDP frames
+   - `--bind-addr 0.0.0.0` — Accept connections from any interface
+   - `--ui-path <path>` — Serve the demo UI via HTTP
+
+3. **Browser Demo** — `main.js` updated to auto-connect to `ws://localhost:8765/ws/sensing` on page load. Falls back to simulated CSI if the WebSocket is unavailable (GitHub Pages).
+
+### Network Configuration
+
+The ESP32 sends UDP packets to a configured target IP. If the PC's IP doesn't match the firmware's compiled target, a secondary IP alias can be added:
+
+```powershell
+# PowerShell (Admin)
+New-NetIPAddress -IPAddress 192.168.1.100 -PrefixLength 24 -InterfaceAlias "Wi-Fi"
+```
+
+### Data Flow
+
+| Stage | Protocol | Format | Rate |
+|-------|----------|--------|------|
+| ESP32 → Server | UDP | ADR-018 binary frame (magic `0xC5110001`, I/Q pairs) | ~100 Hz |
+| Server → Browser | WebSocket | ADR-018 binary frame (forwarded) | ~10 Hz (tick-ms=100) |
+| Browser decode | JavaScript | Float32 amplitude/phase arrays | Per frame |
+
+### Build Environment (Windows)
+
+ESP-IDF v5.4.0 on Windows requires:
+- IDF_PATH pointing to the ESP-IDF framework
+- IDF_TOOLS_PATH pointing to toolchain binaries
+- MSYS/MinGW environment variables removed (ESP-IDF rejects them)
+- Python venv from ESP-IDF tools for `idf.py` execution
+
+The `build_firmware.ps1` script handles all of this automatically.
+
+## Consequences
+
+### Positive
+- First end-to-end demonstration of real WiFi CSI → pose estimation in a browser
+- No Docker required for firmware builds on Windows
+- Demo gracefully degrades to simulated CSI when no server is available
+- Same demo works on GitHub Pages (simulated) and locally (live ESP32)
+
+### Negative
+- ESP32 target IP is compiled into firmware; changing it requires a rebuild or NVS override
+- Windows firewall may block UDP:5005; user must allow it
+- Mixed content restrictions prevent HTTPS pages from connecting to ws:// (local only)

+# 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)

+| Swarm | A group of N QEMU ESP32-S3 instances running simultaneously |
+| Topology | How nodes are connected: star, mesh, line, ring |
+| Role | Node function: `sensor` (collects CSI), `coordinator` (aggregates + forwards), `gateway` (bridges to host) |
+| Scenario matrix | Cross-product of topology × node count × NVS config × mock scenario |
+| Health oracle | Python process that monitors all node UART logs and declares swarm health |
+
+## Context
+
+ADR-061 Layer 3 provides a basic multi-node mesh test: N identical nodes with sequential TDM slots connected via a Linux bridge. This is useful but limited:
+
+1. **All nodes are identical** — real deployments have heterogeneous roles (sensor, coordinator, gateway)
+2. **Single topology** — only fully-connected bridge; no star, line, or ring topologies
+3. **No scenario variation per node** — all nodes run the same mock CSI scenario
+4. **Manual configuration** — each test requires hand-editing env vars and arguments
+5. **No swarm-level health monitoring** — validation checks individual nodes, not collective behavior
+6. **No cross-node timing validation** — TDM slot ordering and inter-frame gaps aren't verified
+
+Real WiFi-DensePose deployments use 3-8 ESP32-S3 nodes in various topologies. A single coordinator aggregates CSI from multiple sensors. The firmware must handle TDM conflicts, missing nodes, role-based behavior differences, and network partitions — none of which ADR-061 Layer 3 tests.
+
+## Decision
+
+Build a **QEMU Swarm Configurator** — a YAML-driven tool that defines multi-node test scenarios declaratively and orchestrates them under QEMU with swarm-level validation.

+```
+
+### Topologies
+
+| Topology | Network | Description |
+|----------|---------|-------------|
+| `star` | All sensors connect to coordinator; coordinator has TAP to each sensor | Hub-and-spoke, most common |
+| `mesh` | All nodes on same bridge (existing Layer 3 behavior) | Every node sees every other |
+| `line` | Node 0 ↔ Node 1 ↔ Node 2 ↔ ... | Linear chain, tests multi-hop |
+| `ring` | Like line but last connects to first | Circular, tests routing |
+
+### Node Roles
+
+| Role | Behavior | NVS Keys |
+|------|----------|----------|
+| `sensor` | Runs mock CSI, sends frames to coordinator | `node_id`, `tdm_slot`, `target_ip` |
+| `coordinator` | Receives frames from sensors, runs edge aggregation | `node_id`, `tdm_slot=0`, `edge_tier=2` |
+| `gateway` | Like coordinator but also bridges to host UDP | `node_id`, `target_ip=host`, `is_gateway=1` |
+
+### Assertions (Swarm-Level)
+
+| Assertion | What It Checks |
+|-----------|---------------|
+| `all_nodes_boot` | Every node's UART log shows boot indicators within timeout |
+| `no_crashes` | No Guru Meditation, assert, panic in any log |
+| `tdm_no_collision` | No two nodes transmit in the same TDM slot |
+| `all_nodes_produce_frames` | Every sensor node's log contains CSI frame output |
+| `coordinator_receives_from_all` | Coordinator log shows frames from each sensor's node_id |
+| `fall_detected_by_node_N` | Node N's log reports a fall detection event |
+| `frame_rate_above` | Each node produces at least N frames/second |
+| `max_boot_time_s` | All nodes boot within N seconds |
+| `no_heap_errors` | No OOM or heap corruption in any log |
+| `network_partitioned_recovery` | After deliberate partition, nodes resume communication (future) |
+
+### Preset Configurations
+
+| Preset | Nodes | Topology | Purpose |
+|--------|-------|----------|---------|
+| `smoke` | 2 | star | Quick CI smoke test (15s) |
+| `standard` | 3 | star | Default 3-node (sensor + sensor + coordinator) |
+| `large-mesh` | 6 | mesh | Scale test with 6 fully-connected nodes |
+| `line-relay` | 4 | line | Multi-hop relay chain |
+| `ring-fault` | 4 | ring | Ring with fault injection mid-test |
+| `heterogeneous` | 5 | star | Mixed scenarios: walk, fall, static, channel-sweep, empty |
+| `ci-matrix` | 3 | star | CI-optimized preset (30s, minimal assertions) |

+
+## Consequences
+
+### Benefits
+
+1. **Declarative testing** — define swarm topology in YAML, not shell scripts
+2. **Role-based nodes** — test coordinator/sensor/gateway interactions
+3. **Topology variety** — star/mesh/line/ring match real deployment patterns
+4. **Swarm-level assertions** — validate collective behavior, not just individual nodes
+5. **Preset library** — quick CI smoke tests and thorough manual validation
+6. **Reproducible** — YAML configs are version-controlled and shareable
+
+### Limitations
+
+1. **Still requires root** for TAP bridge topologies (star, line, ring); mesh can use SLIRP
+2. **QEMU resource usage** — 6+ QEMU instances use ~2GB RAM, may slow CI runners
+3. **No real RF** — inter-node communication is IP-based, not WiFi CSI multipath

+## Testing Firmware Without Hardware (QEMU)
+
+You can test the ESP32-S3 firmware on your computer without any physical hardware. The project uses **QEMU** — an emulator that pretends to be an ESP32-S3 chip, running the real firmware code inside a virtual machine on your PC.
+
+This is useful when:
+- You don't have an ESP32-S3 board yet
+- You want to test firmware changes before flashing to real hardware
+- You're running automated tests in CI/CD
+- You want to simulate multiple ESP32 nodes talking to each other
+
+### What You Need
+
+**Required:**
+- Python 3.8+ (you probably already have this)
+- QEMU with ESP32-S3 support (Espressif's fork)
+
+**Install QEMU (one-time setup):**
+
+```bash
+# Easiest: use the automated installer (installs QEMU + Python tools)
+bash scripts/install-qemu.sh
+
+# Or check what's already installed:
+bash scripts/install-qemu.sh --check
+```
+
+The installer detects your OS (Ubuntu, Fedora, macOS, etc.), installs build dependencies, clones Espressif's QEMU fork, builds it, and adds it to your PATH. It also installs the Python tools (`esptool`, `pyyaml`, `esp-idf-nvs-partition-gen`).

+<summary>Manual installation (if you prefer)</summary>
+
+```bash
+# Build from source
+git clone https://github.com/espressif/qemu.git
+cd qemu
+./configure --target-list=xtensa-softmmu --enable-slirp
+make -j$(nproc)
+export QEMU_PATH=$(pwd)/build/qemu-system-xtensa
+
+# Install Python tools
+pip install esptool pyyaml esp-idf-nvs-partition-gen
+```
+
+</details>
+
+**For multi-node testing (optional):**
+
+```bash
+# Linux only — needed for virtual network bridges
+sudo apt install socat bridge-utils iproute2
+```
+
+### The `qemu-cli.sh` Command
+
+All QEMU testing is available through a single command:
+
+```bash
+bash scripts/qemu-cli.sh <command>
+```
+
+| Command | What it does |
+|---------|-------------|
+| `install` | Install QEMU (runs the installer above) |
+| `test` | Run single-node firmware test |
+| `swarm --preset smoke` | Quick 2-node swarm test |
+| `swarm --preset standard` | Standard 3-node test |
+| `mesh 3` | Multi-node mesh test |
+| `chaos` | Fault injection resilience test |
+| `fuzz --duration 60` | Run fuzz testing |
+| `status` | Show what's installed and ready |
+| `help` | Show all commands |
+
+### Your First Test Run
+
+The simplest way to test the firmware:
+
+```bash
+# Using the CLI:
+bash scripts/qemu-cli.sh test
+
+# Or directly:
+bash scripts/qemu-esp32s3-test.sh
+```
+
+**What happens behind the scenes:**
+1. The firmware is compiled with a "mock CSI" mode — instead of reading real WiFi signals, it generates synthetic test data that mimics real people walking, falling, or breathing
+2. The compiled firmware is loaded into QEMU, which boots it like a real ESP32-S3
+3. The emulator's serial output (what you'd see on a USB cable) is captured
+4. A validation script checks the output for expected behavior and errors
+
+If you already built the firmware and want to skip rebuilding:
+
+```bash
+SKIP_BUILD=1 bash scripts/qemu-esp32s3-test.sh
+```
+
+To give it more time (useful on slower machines):
+
+```bash
+QEMU_TIMEOUT=120 bash scripts/qemu-esp32s3-test.sh
+```
+
+### Understanding the Test Output
+
+The test runs 16 checks on the firmware's output. Here's what a successful run looks like:
+
+```
+=== QEMU ESP32-S3 Firmware Test (ADR-061) ===
+
+[PASS] Boot: Firmware booted successfully
+[PASS] NVS config: Configuration loaded from flash
+[PASS] Mock CSI: Synthetic WiFi data generator started
+[PASS] Edge processing: Signal analysis pipeline running
+[PASS] Frame serialization: Data packets formatted correctly
+[PASS] No crashes: No error conditions detected
+...
+
+16/16 checks passed
+=== Test Complete (exit code: 0) ===
+```
+
+**Exit codes explained:**
+
+| Code | Meaning | What to do |
+|------|---------|-----------|
+| 0 | **PASS** — everything works | Nothing, you're good! |
+| 1 | **WARN** — minor issues | Review the output; usually safe to continue |
+| 2 | **FAIL** — something broke | Check the `[FAIL]` lines for what went wrong |
+| 3 | **FATAL** — can't even start | Usually a missing tool or build failure; check error messages |
+
+### Testing Multiple Nodes at Once (Swarm)
+
+Real deployments use 3-8 ESP32 nodes. The **swarm configurator** lets you simulate multiple nodes on your computer, each with a different role:
+
+- **Sensor nodes** — generate WiFi signal data (like ESP32s placed around a room)
+- **Coordinator node** — collects data from all sensors and runs analysis
+- **Gateway node** — bridges data to your computer
+
+```bash
+# Quick 2-node smoke test (15 seconds)
+python3 scripts/qemu_swarm.py --preset smoke
+
+# Standard 3-node test: 2 sensors + 1 coordinator (60 seconds)
+python3 scripts/qemu_swarm.py --preset standard
+
+# See what's available
+python3 scripts/qemu_swarm.py --list-presets
+
+# Preview what would run (without actually running)
+python3 scripts/qemu_swarm.py --preset standard --dry-run
+```
+
+**Note:** Multi-node testing with virtual bridges requires Linux and `sudo`. On other systems, nodes use a simpler networking mode where each node can reach the coordinator but not each other.
+
+### Swarm Presets
+
+| Preset | Nodes | Duration | Best for |
+|--------|-------|----------|----------|
+| `smoke` | 2 | 15s | Quick check that things work |
+| `standard` | 3 | 60s | Normal development testing |
+| `ci_matrix` | 3 | 30s | CI/CD pipelines |
+| `large_mesh` | 6 | 90s | Testing at scale |
+| `line_relay` | 4 | 60s | Multi-hop relay testing |
+| `ring_fault` | 4 | 75s | Fault tolerance testing |
+| `heterogeneous` | 5 | 90s | Mixed scenario testing |
+
+### Writing Your Own Swarm Config
+
+Create a YAML file describing your test scenario:
+
+```yaml
+# my_test.yaml
+swarm:
+  name: my-custom-test
+  duration_s: 45
+  topology: star       # star, mesh, line, or ring
+  aggregator_port: 5005
+
+nodes:
+  - role: coordinator
+    node_id: 0
+    scenario: 0        # 0=empty room (baseline)
+    channel: 6
+    edge_tier: 2
+
+  - role: sensor
+    node_id: 1
+    scenario: 2        # 2=walking person
+    channel: 6
+    tdm_slot: 1
+
+  - role: sensor
+    node_id: 2
+    scenario: 3        # 3=fall event
+    channel: 6
+    tdm_slot: 2
+
+assertions:
+  - all_nodes_boot           # Did every node start up?
+  - no_crashes               # Any error/panic?
+  - all_nodes_produce_frames # Is each sensor generating data?
+  - fall_detected_by_node_2  # Did node 2 detect the fall?
+```
+
+**Available scenarios** (what kind of fake WiFi data to generate):
+
+| # | Scenario | Description |
+|---|----------|-------------|
+| 0 | Empty room | Baseline with just noise |
+| 1 | Static person | Someone standing still |
+| 2 | Walking | Someone walking across the room |
+| 3 | Fall | Someone falling down |
+| 4 | Multiple people | Two people in the room |
+| 5 | Channel sweep | Cycling through WiFi channels |
+| 6 | MAC filter | Testing device filtering |
+| 7 | Ring overflow | Stress test with burst of data |
+| 8 | RSSI sweep | Signal strength from weak to strong |
+| 9 | Zero-length | Edge case: empty data packet |
+
+**Topology options:**
+
+| Topology | Shape | When to use |
+|----------|-------|-------------|
+| `star` | All sensors connect to one coordinator | Most common setup |
+| `mesh` | Every node can talk to every other | Testing fully connected networks |
+| `line` | Nodes in a chain (A → B → C → D) | Testing relay/forwarding |
+| `ring` | Chain with ends connected | Testing circular routing |
+
+Run your custom config:
+
+```bash
+python3 scripts/qemu_swarm.py --config my_test.yaml
+```
+
+### Debugging Firmware in QEMU
+
+If something goes wrong, you can attach a debugger to the emulated ESP32:
+
+```bash
+# Terminal 1: Start QEMU with debug support (paused at boot)
+qemu-system-xtensa -machine esp32s3 -nographic \
+  -drive file=firmware/esp32-csi-node/build/qemu_flash.bin,if=mtd,format=raw \
+  -s -S
+
+# Terminal 2: Connect the debugger
+xtensa-esp-elf-gdb firmware/esp32-csi-node/build/esp32-csi-node.elf \
+  -ex "target remote :1234" \
+  -ex "break app_main" \
+  -ex "continue"
+```
+
+Or use VS Code: open the project, press **F5**, and select **"QEMU ESP32-S3 Debug"**.
+
+### Running the Full Test Suite
+
+For thorough validation before submitting a pull request:
+
+```bash
+# 1. Single-node test (2 minutes)
+bash scripts/qemu-esp32s3-test.sh
+
+# 2. Multi-node swarm test (1 minute)
+python3 scripts/qemu_swarm.py --preset standard
+
+# 3. Fuzz testing — finds edge-case crashes (1-5 minutes)
+cd firmware/esp32-csi-node/test
+make all CC=clang
+make run_serialize FUZZ_DURATION=60
+make run_edge FUZZ_DURATION=60
+make run_nvs FUZZ_DURATION=60
+
+# 4. NVS configuration matrix — tests 14 config combinations
+python3 scripts/generate_nvs_matrix.py --output-dir build/nvs_matrix
+
+# 5. Chaos testing — injects faults to test resilience (2 minutes)
+bash scripts/qemu-chaos-test.sh
+```
+
+All of these also run automatically in CI when you push changes to `firmware/`.

+## QEMU Testing (ADR-061)
+
+Test the firmware without physical hardware using Espressif's QEMU fork. A compile-time mock CSI generator (`CONFIG_CSI_MOCK_ENABLED=y`) replaces the real WiFi CSI callback with a timer-driven synthetic frame injector that exercises the full edge processing pipeline -- biquad filtering, Welford stats, top-K selection, presence/fall detection, and vitals extraction.
+
+### Prerequisites
+
+- **ESP-IDF v5.4** -- [installation guide](https://docs.espressif.com/projects/esp-idf/en/v5.4/esp32s3/get-started/)
+- **Espressif QEMU fork** -- must be built from source (not in Ubuntu packages):
+
+```bash
+git clone --depth 1 https://github.com/espressif/qemu.git /tmp/qemu
+cd /tmp/qemu
+./configure --target-list=xtensa-softmmu --enable-slirp
+make -j$(nproc)
+sudo cp build/qemu-system-xtensa /usr/local/bin/
+```
+
+### Quick Start
+
+Three commands to go from source to running firmware in QEMU:
+
+```bash
+cd firmware/esp32-csi-node
+
+# 1. Build with mock CSI enabled (replaces real WiFi CSI with synthetic frames)
+idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.qemu" build
+
+# 2. Create merged flash image
+esptool.py --chip esp32s3 merge_bin -o build/qemu_flash.bin \
+  --flash_mode dio --flash_freq 80m --flash_size 8MB \
+  0x0     build/bootloader/bootloader.bin \
+  0x8000  build/partition_table/partition-table.bin \
+  0x20000 build/esp32-csi-node.bin
+
+# 3. Run in QEMU
+qemu-system-xtensa -machine esp32s3 -nographic \
+  -drive file=build/qemu_flash.bin,if=mtd,format=raw \
+  -serial mon:stdio -no-reboot
+```
+
+The firmware boots FreeRTOS, loads NVS config, starts the mock CSI generator at 20 Hz, and runs all edge processing. UART output shows log lines that can be validated automatically.
+
+### Mock CSI Scenarios
+
+The mock generator cycles through 10 scenarios that exercise every edge processing path:
+
+| ID | Scenario | Duration | Expected Output |
+|----|----------|----------|-----------------|
+| 0 | Empty room | 10 s | `presence=0`, `motion_energy < thresh` |
+| 1 | Static person | 10 s | `presence=1`, `breathing_rate` in [10, 25], `fall=0` |
+| 2 | Walking person | 10 s | `presence=1`, `motion_energy > 0.5`, `fall=0` |
+| 3 | Fall event | 5 s | `fall=1` flag set, `motion_energy` spike |
+| 4 | Multi-person | 15 s | `n_persons=2`, independent breathing rates |
+| 5 | Channel sweep | 5 s | Frames on channels 1, 6, 11 in sequence |
+| 6 | MAC filter test | 5 s | Frames with wrong MAC dropped (counter check) |
+| 7 | Ring buffer overflow | 3 s | 1000 frames in 100 ms burst, graceful drop |
+| 8 | Boundary RSSI | 5 s | RSSI sweeps -127 to 0, no crash |
+| 9 | Zero-length frame | 2 s | `iq_len=0` frames, serialize returns 0 |
+
+### NVS Provisioning Matrix
+
+14 NVS configurations are tested in CI to ensure all config paths work correctly:
+
+| 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=<32B> | 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` | (partial/corrupt partition) | Graceful fallback to defaults |
+
+Generate all configs for CI testing:
+
+```bash
+python scripts/generate_nvs_matrix.py
+```
+
+### Validation Checks
+
+The output validation script (`scripts/validate_qemu_output.py`) parses UART logs and checks:
+
+| Check | Pass Criteria | Severity |
+|-------|---------------|----------|
+| Boot | `app_main()` called, no panic/assert | FATAL |
+| NVS load | `nvs_config:` log line present | FATAL |
+| Mock CSI init | `mock_csi: Starting mock CSI generator` | FATAL |
+| Frame generation | `mock_csi: Generated N frames` where N > 0 | ERROR |
+| Edge pipeline | `edge_processing: DSP task started on Core 1` | ERROR |
+| Vitals output | At least one `vitals:` log line with valid BPM | ERROR |
+| Presence detection | `presence=1` during person scenarios | WARN |
+| Fall detection | `fall=1` during fall scenario | WARN |
+| MAC filter | `csi_collector: MAC filter dropped N frames` where N > 0 | WARN |
+| ADR-018 serialize | `csi_collector: Serialized N frames` where N > 0 | ERROR |
+| No crash | No `Guru Meditation Error`, no `assert failed`, no `abort()` | FATAL |
+| Clean exit | Firmware reaches end of scenario sequence | ERROR |
+| Heap OK | No `HEAP_ERROR` or `out of memory` | FATAL |
+| Stack OK | No `Stack overflow` detected | FATAL |
+
+Exit codes: `0` = all pass, `1` = WARN only, `2` = ERROR, `3` = FATAL.
+

+Key breakpoints:
+
+| Location | Purpose |
+|----------|---------|
+| `edge_processing.c:dsp_task` | DSP consumer loop entry |
+| `edge_processing.c:presence_detect` | Threshold comparison |
+| `edge_processing.c:fall_detect` | Phase acceleration check |
+| `csi_collector.c:csi_serialize_frame` | ADR-018 serialization |

+| `wasm_runtime.c:wasm_on_csi` | WASM module dispatch |
+| `mock_csi.c:mock_generate_csi_frame` | Synthetic frame generation |
+
+VS Code integration -- add to `.vscode/launch.json`:
+
+```json
+{
+  "name": "QEMU ESP32-S3 Debug",
+  "type": "cppdbg",
+  "request": "launch",
+  "program": "${workspaceFolder}/firmware/esp32-csi-node/build/esp32-csi-node.elf",

+    { "text": "set remote hardware-watchpoint-limit 2" }
+  ]
+}
+```
+
+### Code Coverage
+
+Build with gcov enabled and collect coverage after a QEMU run:
+
+```bash
+# Build with coverage overlay
+idf.py -D SDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.qemu;sdkconfig.coverage" build
+
+# After QEMU run, generate HTML report
+lcov --capture --directory build --output-file coverage.info
+lcov --remove coverage.info '*/esp-idf/*' '*/test/*' --output-file coverage_filtered.info
+genhtml coverage_filtered.info --output-directory build/coverage_report
+```
+
+Coverage targets:
+
+| Module | Target |
+|--------|--------|
+| `edge_processing.c` | >= 80% |
+| `csi_collector.c` | >= 90% |
+| `nvs_config.c` | >= 95% |
+| `mock_csi.c` | >= 95% |
+| `stream_sender.c` | >= 80% |
+| `wasm_runtime.c` | >= 70% |
+
+### Fuzz Testing
+
+Host-native fuzz targets compiled with libFuzzer + AddressSanitizer (no QEMU needed):
+
+```bash
+cd firmware/esp32-csi-node/test
+
+# Build fuzz target
+clang -fsanitize=fuzzer,address -I../main \
+  fuzz_csi_serialize.c ../main/csi_collector.c \
+  -o fuzz_serialize
+
+# Run for 5 minutes
+timeout 300 ./fuzz_serialize corpus/ || true
+```
+
+Fuzz targets:
+
+| Target | Input | Looking For |
+|--------|-------|-------------|
+| `csi_serialize_frame()` | Random `wifi_csi_info_t` | Buffer overflow, NULL deref |
+| `nvs_config_load()` | Crafted NVS partition binary | No crash, fallback to defaults |
+| `edge_enqueue_csi()` | Rapid-fire 10,000 frames | Ring overflow, no data corruption |
+| `rvf_parser.c` | Malformed RVF packets | Parse rejection, no crash |
+| `wasm_upload.c` | Corrupt WASM blobs | Rejection without crash |
+
+### QEMU CI Workflow
+
+The GitHub Actions workflow (`.github/workflows/firmware-qemu.yml`) runs on every push or PR touching `firmware/**`:
+
+1. Uses the `espressif/idf:v5.4` container image
+2. Builds Espressif's QEMU fork from source
+3. Runs a CI matrix across NVS configurations: `default`, `nvs-full`, `nvs-edge-tier0`, `nvs-tdm-3node`
+4. For each config: provisions NVS, builds with mock CSI, runs in QEMU with timeout, validates UART output
+5. Uploads QEMU logs as build artifacts for debugging failures
+
+No physical ESP32 hardware is needed in CI.

+ * @brief ADR-061 Mock CSI generator for ESP32-S3 QEMU testing.
+ *
+ * Generates synthetic CSI frames at 20 Hz using an esp_timer callback,
+ * injecting them directly into the edge processing pipeline. This allows
+ * full-stack testing of the CSI signal processing, vitals extraction,
+ * and presence detection pipeline under QEMU without WiFi hardware.
+ *
+ * Signal model per subcarrier k at time t:
+ *   A_k(t) = A_base + A_person * exp(-d_k^2 / sigma^2) + noise
+ *   phi_k(t) = phi_base + (2*pi*d / lambda) + breathing_mod(t) + noise
+ *
+ * The entire file is guarded by CONFIG_CSI_MOCK_ENABLED so it compiles
+ * to nothing on production builds.
