Verification Steps (Reproducible)

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

Step 1: Clone and Checkout

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

Step 2: Rust Workspace — Full Test Suite

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

# 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

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

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

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

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

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

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

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 10b: Verify CIR Deterministic Proof (ADR-134)

bash scripts/verify-cir-proof.sh

Expected: VERDICT: PASS (CIR hash matches) once the cir module is implemented.

Currently outputs BLOCKED because expected_cir_features.sha256 contains a placeholder. After the CIR implementation lands, regenerate and commit the hash:

cd v2 && cargo run -p wifi-densepose-signal --bin cir_proof_runner \
  --release --no-default-features -- --generate-hash \
  > ../archive/v1/data/proof/expected_cir_features.sha256

---

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

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
