## Verification Steps (Reproducible)

Anyone can re-run these checks. Each step includes the exact command and expected output.

### Step 1: Clone and Checkout

```bash
git clone https://github.com/ruvnet/wifi-densepose.git
cd wifi-densepose
git checkout 96b01008
```

### Step 2: Rust Workspace — Full Test Suite

```bash
cd v2
cargo test --workspace --no-default-features
```

**Expected:** 1,031 passed, 0 failed, 8 ignored (across all 15 crates).

**Test breakdown by crate family:**

| Crate Group | Tests | Category |
|-------------|-------|----------|
| wifi-densepose-signal | 105+ | Signal processing (Hampel, Fresnel, BVP, spectrogram, phase, motion) |
| wifi-densepose-train | 174+ | Training pipeline, metrics, losses, dataset, model, proof, MERIDIAN |
| wifi-densepose-nn | 23 | Neural network inference, DensePose head, translator |
| wifi-densepose-mat | 153 | Disaster detection, triage, localization, alerting |
| wifi-densepose-hardware | 32 | ESP32 parser, CSI frames, bridge, aggregator |
| wifi-densepose-vitals | Included | Breathing, heartrate, anomaly detection |
| wifi-densepose-wifiscan | Included | WiFi scanning adapters (Windows, macOS, Linux) |
| Doc-tests (all crates) | 11 | Inline documentation examples |

### Step 3: Verify Crate Publication

```bash
# Check all 15 crates are published at v0.2.0
for crate in core config db signal nn api hardware mat train ruvector wasm vitals wifiscan sensing-server cli; do
  echo -n "wifi-densepose-$crate: "
  curl -s "https://crates.io/api/v1/crates/wifi-densepose-$crate" | grep -o '"max_version":"[^"]*"'
done
```

**Expected:** All return `"max_version":"0.2.0"`.

### Step 4: Verify ESP32 Firmware Exists

```bash
ls firmware/esp32-csi-node/main/*.c firmware/esp32-csi-node/main/*.h
wc -l firmware/esp32-csi-node/main/*.c firmware/esp32-csi-node/main/*.h
```

**Expected:** 7 files, 606 total lines:
- `main.c` (144), `csi_collector.c` (176), `stream_sender.c` (77), `nvs_config.c` (88)
- `csi_collector.h` (38), `stream_sender.h` (44), `nvs_config.h` (39)

### Step 5: Verify Pre-Built Firmware Binaries

```bash
ls firmware/esp32-csi-node/build/bootloader/bootloader.bin
ls firmware/esp32-csi-node/build/*.bin 2>/dev/null || echo "App binary in build/esp32-csi-node.bin"
```

**Expected:** `bootloader.bin` exists. App binary present in build directory.

### Step 6: Verify ADR-018 Binary Frame Parser

```bash
cd v2
cargo test -p wifi-densepose-hardware --no-default-features
```

**Expected:** 32 tests pass, including:
- `parse_valid_frame` — validates magic 0xC5110001, field extraction
- `parse_invalid_magic` — rejects non-CSI data
- `parse_insufficient_data` — rejects truncated frames
- `multi_antenna_frame` — handles MIMO configurations
- `amplitude_phase_conversion` — I/Q → (amplitude, phase) math
- `bridge_from_known_iq` — hardware→signal crate bridge

### Step 7: Verify Signal Processing Algorithms

```bash
cargo test -p wifi-densepose-signal --no-default-features
```

**Expected:** 105+ tests pass covering:
- Hampel outlier filtering
- Fresnel zone breathing model
- BVP (Body Velocity Profile) extraction
- STFT spectrogram generation
- Phase sanitization and unwrapping
- Hardware normalization (ESP32-S3 → canonical 56 subcarriers)

### Step 8: Verify MERIDIAN Domain Generalization

```bash
cargo test -p wifi-densepose-train --no-default-features
```

**Expected:** 174+ tests pass, including ADR-027 modules:
- `domain_within_configured_ranges` — virtual domain parameter bounds
- `augment_frame_preserves_length` — output shape correctness
- `augment_frame_identity_domain_approx_input` — identity transform ≈ input
- `deterministic_same_seed_same_output` — reproducibility
- `adapt_empty_buffer_returns_error` — no panic on empty input
- `adapt_zero_rank_returns_error` — no panic on invalid config
- `buffer_cap_evicts_oldest` — bounded memory (max 10,000 frames)

### Step 9: Verify Python Proof System

```bash
python archive/v1/data/proof/verify.py
```

**Expected:** PASS (hash `8c0680d7...` matches `expected_features.sha256`).
Requires numpy 2.4.2 + scipy 1.17.1 (Python 3.13). Hash was regenerated at audit time.

```
VERDICT: PASS
Pipeline hash: 8c0680d7d285739ea9597715e84959d9c356c87ee3ad35b5f1e69a4ca41151c6
```

### Step 10: Verify Docker Images

```bash
docker pull ruvnet/wifi-densepose:latest
docker inspect ruvnet/wifi-densepose:latest --format='{{.Size}}'
# Expected: ~132 MB

docker pull ruvnet/wifi-densepose:python
docker inspect ruvnet/wifi-densepose:python --format='{{.Size}}'
# Expected: ~569 MB
```

### Step 11: Verify ESP32 Flash (requires hardware on COM7)

```bash
pip install esptool
python -m esptool --chip esp32s3 --port COM7 chip_id
# Expected: ESP32-S3 chip ID response

# Full flash (optional)
python -m esptool --chip esp32s3 --port COM7 --baud 460800 \
  write_flash --flash_mode dio --flash_size 4MB \
  0x0 firmware/esp32-csi-node/build/bootloader/bootloader.bin \
  0x8000 firmware/esp32-csi-node/build/partition_table/partition-table.bin \
  0x10000 firmware/esp32-csi-node/build/esp32-csi-node.bin
```

## How to Use This Log

### For Developers
1. Clone the repo at the witness commit
2. Run Steps 2-8 to confirm all code compiles and tests pass
3. Use the ADR-028 capability matrix to understand what's real vs. planned
4. The `firmware/` directory has everything needed to flash an ESP32-S3 on COM7

### For Reviewers / Due Diligence
1. Run Steps 2-10 (no hardware needed) to confirm all software claims
2. Check the attestation matrix — rows marked **YES** have passing test evidence
3. Rows marked **NO** or **NOT MEASURED** are honest gaps, not hidden
4. The proof system (Step 9) demonstrates commitment to verifiability

### For Hardware Testers
1. Get an ESP32-S3-DevKitC-1 (~$10)
2. Follow Step 11 to flash firmware
3. Run the aggregator: `cargo run -p wifi-densepose-hardware --bin aggregator`
4. Observe CSI frames streaming on UDP 5005
