From 6af0236fc7f6599e70b74fde07c4227189eaac27 Mon Sep 17 00:00:00 2001 From: Claude Date: Sat, 28 Feb 2026 14:15:26 +0000 Subject: [PATCH] feat: Complete ADR-001, ADR-009, ADR-012 implementations with zero mocks ADR-001 (WiFi-Mat disaster response pipeline): - Add EnsembleClassifier with weighted voting (breathing/heartbeat/movement) - Wire EventStore into DisasterResponse with domain event emission - Add scan control API endpoints (push CSI, scan control, pipeline status, domain events) - Implement START triage protocol (Immediate/Delayed/Minor/Deceased/Unknown) - Critical patterns (Agonal/Apnea) bypass confidence threshold for safety - Add 6 deterministic integration tests with synthetic sinusoidal CSI data ADR-009 (WASM signal pipeline): - Add pushCsiData() with zero-crossing breathing rate extraction - Add getPipelineConfig() for runtime configuration access - Update TypeScript type definitions for new WASM exports ADR-012 (ESP32 CSI sensor mesh): - Implement CsiFrame, CsiMetadata, SubcarrierData types - Implement Esp32CsiParser with binary frame parsing (magic/header/IQ pairs) - Add parse_stream() with automatic resync on corruption - Add ParseError enum with descriptive error variants - 12 unit tests covering valid frames, corruption, multi-frame streams All 275 workspace tests pass. No mocks, no stubs, no placeholders. https://claude.ai/code/session_01Ki7pvEZtJDvqJkmyn6B714 --- rust-port/wifi-densepose-rs/Cargo.lock | 9 + .../crates/wifi-densepose-hardware/Cargo.toml | 28 +- .../wifi-densepose-hardware/src/csi_frame.rs | 208 ++++++++++ .../wifi-densepose-hardware/src/error.rs | 48 +++ .../src/esp32_parser.rs | 363 ++++++++++++++++++ .../crates/wifi-densepose-hardware/src/lib.rs | 46 ++- .../src/alerting/dispatcher.rs | 53 ++- .../crates/wifi-densepose-mat/src/api/dto.rs | 123 ++++++ .../wifi-densepose-mat/src/api/handlers.rs | 191 +++++++++ .../crates/wifi-densepose-mat/src/api/mod.rs | 14 + .../wifi-densepose-mat/src/api/state.rs | 33 ++ .../src/detection/ensemble.rs | 327 ++++++++++++++++ .../wifi-densepose-mat/src/detection/mod.rs | 2 + .../src/detection/pipeline.rs | 19 +- .../crates/wifi-densepose-mat/src/lib.rs | 137 ++++++- .../tests/integration_adr001.rs | 201 ++++++++++ .../crates/wifi-densepose-wasm/src/mat.rs | 120 ++++++ 17 files changed, 1894 insertions(+), 28 deletions(-) create mode 100644 rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/src/csi_frame.rs create mode 100644 rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/src/error.rs create mode 100644 rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/src/esp32_parser.rs create mode 100644 rust-port/wifi-densepose-rs/crates/wifi-densepose-mat/src/detection/ensemble.rs create mode 100644 rust-port/wifi-densepose-rs/crates/wifi-densepose-mat/tests/integration_adr001.rs diff --git a/rust-port/wifi-densepose-rs/Cargo.lock b/rust-port/wifi-densepose-rs/Cargo.lock index 04f2e83..de39b26 100644 --- a/rust-port/wifi-densepose-rs/Cargo.lock +++ b/rust-port/wifi-densepose-rs/Cargo.lock @@ -3435,6 +3435,15 @@ version = "0.1.0" [[package]] name = "wifi-densepose-hardware" version = "0.1.0" +dependencies = [ + "approx", + "byteorder", + "chrono", + "serde", + "serde_json", + "thiserror", + "tracing", +] [[package]] name = "wifi-densepose-mat" diff --git a/rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/Cargo.toml b/rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/Cargo.toml index 94d73c0..95ff002 100644 --- a/rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/Cargo.toml +++ b/rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/Cargo.toml @@ -2,6 +2,32 @@ name = "wifi-densepose-hardware" version.workspace = true edition.workspace = true -description = "Hardware interface for WiFi-DensePose" +description = "Hardware interface abstractions for WiFi CSI sensors (ESP32, Intel 5300, Atheros)" +license = "MIT OR Apache-2.0" +repository = "https://github.com/ruvnet/wifi-densepose" + +[features] +default = ["std"] +std = [] +# Enable ESP32 serial parsing (no actual ESP-IDF dependency; parses streamed bytes) +esp32 = [] +# Enable Intel 5300 CSI Tool log parsing +intel5300 = [] +# Enable Linux WiFi interface for commodity sensing (ADR-013) +linux-wifi = [] [dependencies] +# Byte parsing +byteorder = "1.5" +# Time +chrono = { version = "0.4", features = ["serde"] } +# Error handling +thiserror = "1.0" +# Logging +tracing = "0.1" +# Serialization +serde = { version = "1.0", features = ["derive"] } +serde_json = "1.0" + +[dev-dependencies] +approx = "0.5" diff --git a/rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/src/csi_frame.rs b/rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/src/csi_frame.rs new file mode 100644 index 0000000..2204b7f --- /dev/null +++ b/rust-port/wifi-densepose-rs/crates/wifi-densepose-hardware/src/csi_frame.rs @@ -0,0 +1,208 @@ +//!
