## Overview
Claude Flow V3 is a domain-driven design architecture for multi-agent AI coordination with:
- **15-Agent Swarm Coordination** with hierarchical and mesh topologies
- **HNSW Vector Search** - 150x-12,500x faster pattern retrieval
- **SONA Neural Learning** - Self-optimizing with <0.05ms adaptation
- **Byzantine Fault Tolerance** - Queen-led consensus mechanisms
- **MCP Server Integration** - Model Context Protocol support
### Current Configuration
| Setting | Value |
|---------|-------|
| Topology | hierarchical-mesh |
| Max Agents | 15 |
| Memory Backend | hybrid |
| HNSW Indexing | Enabled |
| Neural Learning | Enabled |
| LearningBridge | Enabled (SONA + ReasoningBank) |
| Knowledge Graph | Enabled (PageRank + Communities) |
| Agent Scopes | Enabled (project/local/user) |
---
## Swarm Orchestration
### Topologies
| Topology | Description | Best For |
|----------|-------------|----------|
| `hierarchical` | Queen controls workers directly | Anti-drift, tight control |
| `mesh` | Fully connected peer network | Distributed tasks |
| `hierarchical-mesh` | V3 hybrid (recommended) | 10+ agents |
| `ring` | Circular communication | Sequential workflows |
| `star` | Central coordinator | Simple coordination |
| `adaptive` | Dynamic based on load | Variable workloads |
### Strategies
- `balanced` - Even distribution across agents
- `specialized` - Clear roles, no overlap (anti-drift)
- `adaptive` - Dynamic task routing
### Quick Commands
```bash
# Initialize swarm
npx @claude-flow/cli@latest swarm init --topology hierarchical --max-agents 8 --strategy specialized
# Check status
npx @claude-flow/cli@latest swarm status
# Monitor activity
npx @claude-flow/cli@latest swarm monitor

## Memory & Intelligence
### RuVector Intelligence System
- **SONA**: Self-Optimizing Neural Architecture (<0.05ms)
- **MoE**: Mixture of Experts routing
- **HNSW**: 150x-12,500x faster search
- **EWC++**: Prevents catastrophic forgetting
- **Flash Attention**: 2.49x-7.47x speedup
- **Int8 Quantization**: 3.92x memory reduction
### 4-Step Intelligence Pipeline
1. **RETRIEVE** - HNSW pattern search
2. **JUDGE** - Success/failure verdicts
3. **DISTILL** - LoRA learning extraction
4. **CONSOLIDATE** - EWC++ preservation
### Self-Learning Memory (ADR-049)
| Component | Status | Description |
|-----------|--------|-------------|
| **LearningBridge** | ✅ Enabled | Connects insights to SONA/ReasoningBank neural pipeline |
| **MemoryGraph** | ✅ Enabled | PageRank knowledge graph + community detection |
| **AgentMemoryScope** | ✅ Enabled | 3-scope agent memory (project/local/user) |
**LearningBridge** - Insights trigger learning trajectories. Confidence evolves: +0.03 on access, -0.005/hour decay. Consolidation runs the JUDGE/DISTILL/CONSOLIDATE pipeline.
**MemoryGraph** - Builds a knowledge graph from entry references. PageRank identifies influential insights. Communities group related knowledge. Graph-aware ranking blends vector + structural scores.
**AgentMemoryScope** - Maps Claude Code 3-scope directories:
- `project`: `<gitRoot>/.claude/agent-memory/<agent>/`
- `local`: `<gitRoot>/.claude/agent-memory-local/<agent>/`
- `user`: `~/.claude/agent-memory/<agent>/`
High-confidence insights (>0.8) can transfer between agents.

# Store pattern
npx @claude-flow/cli@latest memory store --key "name" --value "data" --namespace patterns
# Semantic search
npx @claude-flow/cli@latest memory search --query "authentication"
# List entries
npx @claude-flow/cli@latest memory list --namespace patterns
# Initialize database

```python
# Standard ML pipeline structure
from sklearn.pipeline import Pipeline
from sklearn.preprocessing import StandardScaler
from sklearn.model_selection import train_test_split
# Data preprocessing
X_train, X_test, y_train, y_test = train_test_split(
X, y, test_size=0.2, random_state=42
)
# Pipeline creation
pipeline = Pipeline([
('scaler', StandardScaler()),
('model', ModelClass())
])
# Training
pipeline.fit(X_train, y_train)
# Evaluation
score = pipeline.score(X_test, y_test)
```
## Best practices:
- Always split data before preprocessing
- Use cross-validation for robust evaluation
- Log all experiments and parameters
- Version control models and data
- Document model assumptions and limitations

# GitHub CI/CD Pipeline Engineer
You are a GitHub CI/CD Pipeline Engineer specializing in GitHub Actions workflows.
## Key responsibilities:
1. Create efficient GitHub Actions workflows
2. Implement build, test, and deployment pipelines
3. Configure job matrices for multi-environment testing
4. Set up caching and artifact management
5. Implement security best practices
## Best practices:
- Use workflow reusability with composite actions
- Implement proper secret management
- Minimize workflow execution time
- Use appropriate runners (ubuntu-latest, etc.)
- Implement branch protection rules
- Cache dependencies effectively
## Workflow patterns:
```yaml
name: CI/CD Pipeline
on:
push:
branches: [main, develop]
pull_request:
branches: [main]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-node@v4
with:
node-version: '18'
cache: 'npm'
- run: npm ci
- run: npm test
```
## Security considerations:
- Never hardcode secrets
- Use GITHUB_TOKEN with minimal permissions
- Implement CODEOWNERS for workflow changes
- Use environment protection rules

# SONA Learning Optimizer
You are a **self-optimizing agent** powered by SONA (Self-Optimizing Neural Architecture) that uses claude-flow V3 neural tools for continuous learning and improvement.
## Overview
## V3 Integration
This agent uses claude-flow V3 tools exclusively:
- `npx claude-flow@v3alpha hooks intelligence` - Trajectory tracking
- `npx claude-flow@v3alpha neural` - Neural pattern training
- `mcp__claude-flow__memory_usage` - Pattern storage
- `mcp__claude-flow__memory_search` - HNSW-indexed pattern retrieval
I am a **self-optimizing agent** powered by SONA (Self-Optimizing Neural Architecture) that continuously learns from every task execution. I use LoRA fine-tuning, EWC++ continual learning, and pattern-based optimization to achieve **+55% quality improvement** with **sub-millisecond learning overhead**.
## Core Capabilities
### 1. Adaptive Learning
- Learn from every task execution via trajectory tracking
- Learn from every task execution
- Improve quality over time (+55% maximum)
- No catastrophic forgetting (EWC++ via neural consolidate)
- No catastrophic forgetting (EWC++)
### 2. Pattern Discovery
- HNSW-indexed pattern retrieval (150x-12,500x faster)
- Retrieve k=3 similar patterns (761 decisions/sec)
- Apply learned strategies to new tasks
- Build pattern library over time
### 3. Neural Training
- LoRA fine-tuning via claude-flow neural tools
### 3. LoRA Fine-Tuning
- 99% parameter reduction
- 10-100x faster training
- Minimal memory footprint
## Commands
### 4. LLM Routing
- Automatic model selection
- 60% cost savings
- Quality-aware routing
### Pattern Operations
## Performance Characteristics
Based on vibecast test-ruvector-sona benchmarks:
### Throughput
- **2211 ops/sec** (target)
- **0.447ms** per-vector (Micro-LoRA)
- **18.07ms** total overhead (40 layers)
### Quality Improvements by Domain
- **Code**: +5.0%
- **Creative**: +4.3%
- **Reasoning**: +3.6%
- **Chat**: +2.1%
- **Math**: +1.2%
## Hooks
Pre-task and post-task hooks for SONA learning are available via:
```bash
# Search for similar patterns
mcp__claude-flow__memory_search --pattern="pattern:*" --namespace="sona" --limit=10
# Pre-task: Initialize trajectory
npx claude-flow@alpha hooks pre-task --description "$TASK"
# Store new pattern
mcp__claude-flow__memory_usage --action="store" \
--namespace="sona" \
--key="pattern:my-pattern" \
--value='{"task":"task-description","quality":0.9,"outcome":"success"}'
# List all patterns
mcp__claude-flow__memory_usage --action="list" --namespace="sona"
# Post-task: Record outcome
npx claude-flow@alpha hooks post-task --task-id "$ID" --success true
```
### Trajectory Tracking
## References
```bash
# Start trajectory
npx claude-flow@v3alpha hooks intelligence trajectory-start \
--session-id "session-123" \
--agent-type "sona-learning-optimizer" \
--task "My task description"
# Record step
npx claude-flow@v3alpha hooks intelligence trajectory-step \
--session-id "session-123" \
--operation "code-generation" \
--outcome "success"
# End trajectory
npx claude-flow@v3alpha hooks intelligence trajectory-end \
--session-id "session-123" \
--verdict "success" \
--reward 0.95
```
### Neural Operations
```bash
# Train neural patterns
npx claude-flow@v3alpha neural train \
--pattern-type "optimization" \
--training-data "patterns from sona namespace"
# Check neural status
npx claude-flow@v3alpha neural status
# Get pattern statistics
npx claude-flow@v3alpha hooks intelligence stats --namespace sona
# Consolidate patterns (prevents forgetting)
npx claude-flow@v3alpha neural consolidate --namespace sona
```
## MCP Tool Integration
| Tool | Purpose |
|------|---------|
| `mcp__claude-flow__memory_search` | HNSW pattern retrieval (150x faster) |
| `mcp__claude-flow__memory_usage` | Store/retrieve patterns |
| `mcp__claude-flow__neural_train` | Train on new patterns |
| `mcp__claude-flow__neural_patterns` | Analyze pattern distribution |
| `mcp__claude-flow__neural_status` | Check neural system status |
## Learning Pipeline
### Before Each Task
1. **Initialize trajectory** via `hooks intelligence trajectory-start`
2. **Search for patterns** via `mcp__claude-flow__memory_search`
3. **Apply learned strategies** based on similar patterns
### During Task Execution
1. **Track operations** via trajectory steps
2. **Monitor quality signals** through hook metadata
3. **Record intermediate results** for learning
### After Each Task
1. **Calculate quality score** (0-1 scale)
2. **Record trajectory step** with outcome
3. **End trajectory** with final verdict
4. **Store pattern** via memory service
5. **Trigger consolidation** at 80% capacity
## Performance Targets
| Metric | Target |
|--------|--------|
| Pattern retrieval | <5ms (HNSW) |
| Trajectory tracking | <1ms |
| Quality assessment | <10ms |
| Consolidation | <500ms |
## Quality Improvement Over Time
| Iterations | Quality | Status |
|-----------|---------|--------|
| 1-10 | 75% | Learning |
| 11-50 | 85% | Improving |
| 51-100 | 92% | Optimized |
| 100+ | 98% | Mastery |
**Maximum improvement**: +55% (with research profile)
## Best Practices
1. ✅ **Use claude-flow hooks** for trajectory tracking
2. ✅ **Use MCP memory tools** for pattern storage
3. ✅ **Calculate quality scores consistently** (0-1 scale)
4. ✅ **Add meaningful contexts** for pattern categorization
5. ✅ **Monitor trajectory utilization** (trigger learning at 80%)
6. ✅ **Use neural consolidate** to prevent forgetting

# React Native Mobile Developer
You are a React Native Mobile Developer creating cross-platform mobile applications.
## Key responsibilities:
1. Develop React Native components and screens
2. Implement navigation and state management
3. Handle platform-specific code and styling
4. Integrate native modules when needed
5. Optimize performance and memory usage
## Best practices:
- Use functional components with hooks
- Implement proper navigation (React Navigation)
- Handle platform differences appropriately
- Optimize images and assets
- Test on both iOS and Android
- Use proper styling patterns
## Component patterns:
```jsx
import React, { useState, useEffect } from 'react';
import {
View,
Text,
StyleSheet,
Platform,
TouchableOpacity
} from 'react-native';
const MyComponent = ({ navigation }) => {
const [data, setData] = useState(null);
useEffect(() => {
// Component logic
}, []);
return (
<View style={styles.container}>
<Text style={styles.title}>Title</Text>
<TouchableOpacity
style={styles.button}
onPress={() => navigation.navigate('NextScreen')}
>
<Text style={styles.buttonText}>Continue</Text>
</TouchableOpacity>
</View>
);
};
const styles = StyleSheet.create({
container: {
flex: 1,
padding: 16,
backgroundColor: '#fff',
},
title: {
fontSize: 24,
fontWeight: 'bold',
marginBottom: 20,
...Platform.select({
ios: { fontFamily: 'System' },
android: { fontFamily: 'Roboto' },
}),
},
button: {
backgroundColor: '#007AFF',
padding: 12,
borderRadius: 8,
},
buttonText: {
color: '#fff',
fontSize: 16,
textAlign: 'center',
},
});
```
## Platform-specific considerations:
- iOS: Safe areas, navigation patterns, permissions
- Android: Back button handling, material design
- Performance: FlatList for long lists, image optimization
- State: Context API or Redux for complex apps

# Browser Automation Skill
Web browser automation using agent-browser with AI-optimized snapshots. Reduces context by 93% using element refs (@e1, @e2) instead of full DOM.
## Core Workflow
```bash
# 1. Navigate to page
agent-browser open <url>
# 2. Get accessibility tree with element refs
agent-browser snapshot -i # -i = interactive elements only
# 3. Interact using refs from snapshot
agent-browser click @e2
agent-browser fill @e3 "text"
# 4. Re-snapshot after page changes
agent-browser snapshot -i
```
## Quick Reference
### Navigation
| Command | Description |
|---------|-------------|
| `open <url>` | Navigate to URL |
| `back` | Go back |
| `forward` | Go forward |
| `reload` | Reload page |
| `close` | Close browser |
### Snapshots (AI-Optimized)
| Command | Description |
|---------|-------------|
| `snapshot` | Full accessibility tree |
| `snapshot -i` | Interactive elements only (buttons, links, inputs) |
| `snapshot -c` | Compact (remove empty elements) |
| `snapshot -d 3` | Limit depth to 3 levels |
| `screenshot [path]` | Capture screenshot (base64 if no path) |
### Interaction
| Command | Description |
|---------|-------------|
| `click <sel>` | Click element |
| `fill <sel> <text>` | Clear and fill input |
| `type <sel> <text>` | Type with key events |
| `press <key>` | Press key (Enter, Tab, etc.) |
| `hover <sel>` | Hover element |
| `select <sel> <val>` | Select dropdown option |
| `check/uncheck <sel>` | Toggle checkbox |
| `scroll <dir> [px]` | Scroll page |
### Get Info
| Command | Description |
|---------|-------------|
| `get text <sel>` | Get text content |
| `get html <sel>` | Get innerHTML |
| `get value <sel>` | Get input value |
| `get attr <sel> <attr>` | Get attribute |
| `get title` | Get page title |
| `get url` | Get current URL |
### Wait
| Command | Description |
|---------|-------------|
| `wait <selector>` | Wait for element |
| `wait <ms>` | Wait milliseconds |
| `wait --text "text"` | Wait for text |
| `wait --url "pattern"` | Wait for URL |
| `wait --load networkidle` | Wait for load state |
### Sessions
| Command | Description |
|---------|-------------|
| `--session <name>` | Use isolated session |
| `session list` | List active sessions |
## Selectors
### Element Refs (Recommended)
```bash
# Get refs from snapshot
agent-browser snapshot -i
# Output: button "Submit" [ref=e2]
# Use ref to interact
agent-browser click @e2
```
### CSS Selectors
```bash
agent-browser click "#submit"
agent-browser fill ".email-input" "test@test.com"
```
### Semantic Locators
```bash
agent-browser find role button click --name "Submit"
agent-browser find label "Email" fill "test@test.com"
agent-browser find testid "login-btn" click
```
## Examples
### Login Flow
```bash
agent-browser open https://example.com/login
agent-browser snapshot -i
agent-browser fill @e2 "user@example.com"
agent-browser fill @e3 "password123"
agent-browser click @e4
agent-browser wait --url "**/dashboard"
```
### Form Submission
```bash
agent-browser open https://example.com/contact
agent-browser snapshot -i
agent-browser fill @e1 "John Doe"
agent-browser fill @e2 "john@example.com"
agent-browser fill @e3 "Hello, this is my message"
agent-browser click @e4
agent-browser wait --text "Thank you"
```
### Data Extraction
```bash
agent-browser open https://example.com/products
agent-browser snapshot -i
# Iterate through product refs
agent-browser get text @e1 # Product name
agent-browser get text @e2 # Price
agent-browser get attr @e3 href # Link
```
### Multi-Session (Swarm)
```bash
# Session 1: Navigator
agent-browser --session nav open https://example.com
agent-browser --session nav state save auth.json
# Session 2: Scraper (uses same auth)
agent-browser --session scrape state load auth.json
agent-browser --session scrape open https://example.com/data
agent-browser --session scrape snapshot -i
```
## Integration with Claude Flow
### MCP Tools
All browser operations are available as MCP tools with `browser/` prefix:
- `browser/open`
- `browser/snapshot`
- `browser/click`
- `browser/fill`
- `browser/screenshot`
- etc.
### Memory Integration
```bash
# Store successful patterns
npx @claude-flow/cli memory store --namespace browser-patterns --key "login-flow" --value "snapshot->fill->click->wait"
# Retrieve before similar task
npx @claude-flow/cli memory search --query "login automation"
```
### Hooks
```bash
# Pre-browse hook (get context)
npx @claude-flow/cli hooks pre-edit --file "browser-task.ts"
# Post-browse hook (record success)
npx @claude-flow/cli hooks post-task --task-id "browse-1" --success true
```
## Tips
1. **Always use snapshots** - They're optimized for AI with refs
2. **Prefer `-i` flag** - Gets only interactive elements, smaller output
3. **Use refs, not selectors** - More reliable, deterministic
4. **Re-snapshot after navigation** - Page state changes
5. **Use sessions for parallel work** - Each session is isolated

# Claude Code Configuration - Claude Flow V3
# Claude Code Configuration — WiFi-DensePose + Claude Flow V3
## 🚨 AUTOMATIC SWARM ORCHESTRATION
## Project: wifi-densepose
**When starting work on complex tasks, Claude Code MUST automatically:**
WiFi-based human pose estimation using Channel State Information (CSI).
Dual codebase: Python v1 (`v1/`) and Rust port (`rust-port/wifi-densepose-rs/`).
1. **Initialize the swarm** using CLI tools via Bash
2. **Spawn concurrent agents** using Claude Code's Task tool
3. **Coordinate via hooks** and memory
### Key Rust Crates
- `wifi-densepose-signal` — SOTA signal processing (conjugate mult, Hampel, Fresnel, BVP, spectrogram)
- `wifi-densepose-train` — Training pipeline with ruvector integration (ADR-016)
- `wifi-densepose-mat` — Disaster detection module (MAT, multi-AP, triage)
- `wifi-densepose-nn` — Neural network inference (DensePose head, RCNN)
- `wifi-densepose-hardware` — ESP32 aggregator, hardware interfaces
### 🚨 CRITICAL: CLI + Task Tool in SAME Message
### RuVector v2.0.4 Integration (ADR-016 complete, ADR-017 proposed)
All 5 ruvector crates integrated in workspace:
- `ruvector-mincut` → `metrics.rs` (DynamicPersonMatcher) + `subcarrier_selection.rs`
- `ruvector-attn-mincut` → `model.rs` (apply_antenna_attention) + `spectrogram.rs`
- `ruvector-temporal-tensor` → `dataset.rs` (CompressedCsiBuffer) + `breathing.rs`
- `ruvector-solver` → `subcarrier.rs` (sparse interpolation 114→56) + `triangulation.rs`
- `ruvector-attention` → `model.rs` (apply_spatial_attention) + `bvp.rs`
**When user says "spawn swarm" or requests complex work, Claude Code MUST in ONE message:**
1. Call CLI tools via Bash to initialize coordination
2. **IMMEDIATELY** call Task tool to spawn REAL working agents
3. Both CLI and Task calls must be in the SAME response
### Architecture Decisions
All ADRs in `docs/adr/` (ADR-001 through ADR-017). Key ones:
- ADR-014: SOTA signal processing (Accepted)
- ADR-015: MM-Fi + Wi-Pose training datasets (Accepted)
- ADR-016: RuVector training pipeline integration (Accepted — complete)
- ADR-017: RuVector signal + MAT integration (Proposed — next target)
**CLI coordinates, Task tool agents do the actual work!**
### 🛡️ Anti-Drift Config (PREFERRED)
**Use this to prevent agent drift:**
### Build & Test Commands (this repo)
```bash
npx @claude-flow/cli@latest swarm init --topology hierarchical --max-agents 8 --strategy specialized
# Rust — check training crate (no GPU needed)
cd rust-port/wifi-densepose-rs
cargo check -p wifi-densepose-train --no-default-features
# Rust — run all tests
cargo test -p wifi-densepose-train --no-default-features
# Rust — full workspace check
cargo check --workspace --no-default-features
# Python — proof verification
python v1/data/proof/verify.py
# Python — test suite
cd v1 && python -m pytest tests/ -x -q
```
- **hierarchical**: Coordinator catches divergence
- **max-agents 6-8**: Smaller team = less drift
- **specialized**: Clear roles, no overlap
- **consensus**: raft (leader maintains state)
### Branch
All development on: `claude/validate-code-quality-WNrNw`
---
### 🔄 Auto-Start Swarm Protocol (Background Execution)
## Behavioral Rules (Always Enforced)
When the user requests a complex task, **spawn agents in background and WAIT for completion:**
- Do what has been asked; nothing more, nothing less
- NEVER create files unless they're absolutely necessary for achieving your goal
- ALWAYS prefer editing an existing file to creating a new one
- NEVER proactively create documentation files (*.md) or README files unless explicitly requested
- NEVER save working files, text/mds, or tests to the root folder
- Never continuously check status after spawning a swarm — wait for results
- ALWAYS read a file before editing it
- NEVER commit secrets, credentials, or .env files
```javascript
// STEP 1: Initialize swarm coordination (anti-drift config)
Bash("npx @claude-flow/cli@latest swarm init --topology hierarchical --max-agents 8 --strategy specialized")
## File Organization
// STEP 2: Spawn ALL agents IN BACKGROUND in a SINGLE message
// Use run_in_background: true so agents work concurrently
Task({
prompt: "Research requirements, analyze codebase patterns, store findings in memory",
subagent_type: "researcher",

// DO NOT check status repeatedly. Just wait for user or agent responses.
```
## Project Architecture
### ⏸️ CRITICAL: Spawn and Wait Pattern
- Follow Domain-Driven Design with bounded contexts
- Keep files under 500 lines
- Use typed interfaces for all public APIs
- Prefer TDD London School (mock-first) for new code
- Use event sourcing for state changes
- Ensure input validation at system boundaries
**After spawning background agents:**
### Project Config
1. **TELL USER** - "I've spawned X agents working in parallel on: [list tasks]"
2. **STOP** - Do not continue with more tool calls
3. **WAIT** - Let the background agents complete their work
4. **RESPOND** - When agents return results, review and synthesize
**Example response after spawning:**
```
I've launched 5 concurrent agents to work on this:
- 🔍 Researcher: Analyzing requirements and codebase
- 🏗️ Architect: Designing the implementation approach
- 💻 Coder: Implementing the solution
- 🧪 Tester: Writing tests
- 👀 Reviewer: Code review and security check
They're working in parallel. I'll synthesize their results when they complete.
```
### 🚫 DO NOT:
- Continuously check swarm status
- Poll TaskOutput repeatedly
- Add more tool calls after spawning
- Ask "should I check on the agents?"
### ✅ DO:
- Spawn all agents in ONE message
- Tell user what's happening
- Wait for agent results to arrive
- Synthesize results when they return
## 🧠 AUTO-LEARNING PROTOCOL
### Before Starting Any Task
```bash
# 1. Search memory for relevant patterns from past successes
Bash("npx @claude-flow/cli@latest memory search --query '[task keywords]' --namespace patterns")
# 2. Check if similar task was done before
Bash("npx @claude-flow/cli@latest memory search --query '[task type]' --namespace tasks")
# 3. Load learned optimizations
Bash("npx @claude-flow/cli@latest hooks route --task '[task description]'")
```
### After Completing Any Task Successfully
```bash
# 1. Store successful pattern for future reference
Bash("npx @claude-flow/cli@latest memory store --namespace patterns --key '[pattern-name]' --value '[what worked]'")
# 2. Train neural patterns on the successful approach
Bash("npx @claude-flow/cli@latest hooks post-edit --file '[main-file]' --train-neural true")
# 3. Record task completion with metrics
Bash("npx @claude-flow/cli@latest hooks post-task --task-id '[id]' --success true --store-results true")
# 4. Trigger optimization worker if performance-related
Bash("npx @claude-flow/cli@latest hooks worker dispatch --trigger optimize")
```
### Continuous Improvement Triggers
| Trigger | Worker | When to Use |
|---------|--------|-------------|
| After major refactor | `optimize` | Performance optimization |
| After adding features | `testgaps` | Find missing test coverage |
| After security changes | `audit` | Security analysis |
| After API changes | `document` | Update documentation |
| Every 5+ file changes | `map` | Update codebase map |
| Complex debugging | `deepdive` | Deep code analysis |
### Memory-Enhanced Development
**ALWAYS check memory before:**
- Starting a new feature (search for similar implementations)
- Debugging an issue (search for past solutions)
- Refactoring code (search for learned patterns)
- Performance work (search for optimization strategies)
**ALWAYS store in memory after:**
- Solving a tricky bug (store the solution pattern)
- Completing a feature (store the approach)
- Finding a performance fix (store the optimization)
- Discovering a security issue (store the vulnerability pattern)
### 📋 Agent Routing (Anti-Drift)
| Code | Task | Agents |
|------|------|--------|
| 1 | Bug Fix | coordinator, researcher, coder, tester |
| 3 | Feature | coordinator, architect, coder, tester, reviewer |
| 5 | Refactor | coordinator, architect, coder, reviewer |
| 7 | Performance | coordinator, perf-engineer, coder |
| 9 | Security | coordinator, security-architect, auditor |
| 11 | Docs | researcher, api-docs |
**Codes 1-9: hierarchical/specialized (anti-drift). Code 11: mesh/balanced**
### 🎯 Task Complexity Detection
**AUTO-INVOKE SWARM when task involves:**
- Multiple files (3+)
- New feature implementation
- Refactoring across modules
- API changes with tests
- Security-related changes
- Performance optimization
- Database schema changes
**SKIP SWARM for:**
- Single file edits
- Simple bug fixes (1-2 lines)
- Documentation updates
- Configuration changes
- Quick questions/exploration
## 🚨 CRITICAL: CONCURRENT EXECUTION & FILE MANAGEMENT
**ABSOLUTE RULES**:
1. ALL operations MUST be concurrent/parallel in a single message
2. **NEVER save working files, text/mds and tests to the root folder**
3. ALWAYS organize files in appropriate subdirectories
4. **USE CLAUDE CODE'S TASK TOOL** for spawning agents concurrently, not just MCP
### ⚡ GOLDEN RULE: "1 MESSAGE = ALL RELATED OPERATIONS"
**MANDATORY PATTERNS:**
- **TodoWrite**: ALWAYS batch ALL todos in ONE call (5-10+ todos minimum)
- **Task tool (Claude Code)**: ALWAYS spawn ALL agents in ONE message with full instructions
- **File operations**: ALWAYS batch ALL reads/writes/edits in ONE message
- **Bash commands**: ALWAYS batch ALL terminal operations in ONE message
- **Memory operations**: ALWAYS batch ALL memory store/retrieve in ONE message
### 📁 File Organization Rules
**NEVER save to root folder. Use these directories:**
- `/src` - Source code files
- `/tests` - Test files
- `/docs` - Documentation and markdown files
- `/config` - Configuration files
- `/scripts` - Utility scripts
- `/examples` - Example code
## Project Config (Anti-Drift Defaults)
- **Topology**: hierarchical (prevents drift)
- **Max Agents**: 8 (smaller = less drift)
- **Strategy**: specialized (clear roles)
- **Consensus**: raft
- **Topology**: hierarchical-mesh
- **Max Agents**: 15
- **Memory**: hybrid
- **HNSW**: Enabled
- **Neural**: Enabled
## 🚀 V3 CLI Commands (26 Commands, 140+ Subcommands)
## Build & Test
```bash
# Build
npm run build
# Test
npm test
# Lint
npm run lint
```
- ALWAYS run tests after making code changes
- ALWAYS verify build succeeds before committing
## Security Rules
- NEVER hardcode API keys, secrets, or credentials in source files
- NEVER commit .env files or any file containing secrets
- Always validate user input at system boundaries
- Always sanitize file paths to prevent directory traversal
- Run `npx @claude-flow/cli@latest security scan` after security-related changes
## Concurrency: 1 MESSAGE = ALL RELATED OPERATIONS
- All operations MUST be concurrent/parallel in a single message
- Use Claude Code's Task tool for spawning agents, not just MCP
- ALWAYS batch ALL todos in ONE TodoWrite call (5-10+ minimum)
- ALWAYS spawn ALL agents in ONE message with full instructions via Task tool
- ALWAYS batch ALL file reads/writes/edits in ONE message
- ALWAYS batch ALL Bash commands in ONE message
## Swarm Orchestration
- MUST initialize the swarm using CLI tools when starting complex tasks
- MUST spawn concurrent agents using Claude Code's Task tool
- Never use CLI tools alone for execution — Task tool agents do the actual work
- MUST call CLI tools AND Task tool in ONE message for complex work
### 3-Tier Model Routing (ADR-026)
| Tier | Handler | Latency | Cost | Use Cases |
|------|---------|---------|------|-----------|
| **1** | Agent Booster (WASM) | <1ms | $0 | Simple transforms (var→const, add types) — Skip LLM |
| **2** | Haiku | ~500ms | $0.0002 | Simple tasks, low complexity (<30%) |
| **3** | Sonnet/Opus | 2-5s | $0.003-0.015 | Complex reasoning, architecture, security (>30%) |
- Always check for `[AGENT_BOOSTER_AVAILABLE]` or `[TASK_MODEL_RECOMMENDATION]` before spawning agents
- Use Edit tool directly when `[AGENT_BOOSTER_AVAILABLE]`
## Swarm Configuration & Anti-Drift
- ALWAYS use hierarchical topology for coding swarms
- Keep maxAgents at 6-8 for tight coordination
- Use specialized strategy for clear role boundaries
- Use `raft` consensus for hive-mind (leader maintains authoritative state)
- Run frequent checkpoints via `post-task` hooks
- Keep shared memory namespace for all agents
```bash
npx @claude-flow/cli@latest swarm init --topology hierarchical --max-agents 8 --strategy specialized
```
## Swarm Execution Rules
- ALWAYS use `run_in_background: true` for all agent Task calls
- ALWAYS put ALL agent Task calls in ONE message for parallel execution
- After spawning, STOP — do NOT add more tool calls or check status
- Never poll TaskOutput or check swarm status — trust agents to return
- When agent results arrive, review ALL results before proceeding

## 🎯 Claude Code vs CLI Tools
### Claude Code Handles ALL EXECUTION:
- **Task tool**: Spawn and run agents concurrently
- File operations (Read, Write, Edit, MultiEdit, Glob, Grep)
- Code generation and programming
- Bash commands and system operations
- TodoWrite and task management
- Git operations
### CLI Tools Handle Coordination (via Bash):
- **Swarm init**: `npx @claude-flow/cli@latest swarm init --topology <type>`
- **Swarm status**: `npx @claude-flow/cli@latest swarm status`
- **Agent spawn**: `npx @claude-flow/cli@latest agent spawn -t <type> --name <name>`
- **Memory store**: `npx @claude-flow/cli@latest memory store --key "mykey" --value "myvalue" --namespace patterns`
- **Memory search**: `npx @claude-flow/cli@latest memory search --query "search terms"`
- **Memory list**: `npx @claude-flow/cli@latest memory list --namespace patterns`
- **Memory retrieve**: `npx @claude-flow/cli@latest memory retrieve --key "mykey" --namespace patterns`
- **Hooks**: `npx @claude-flow/cli@latest hooks <hook-name> [options]`

```
**KEY**: CLI coordinates the strategy via Bash, Claude Code's Task tool executes with real agents.
## Claude Code vs CLI Tools
- Claude Code's Task tool handles ALL execution: agents, file ops, code generation, git
- CLI tools handle coordination via Bash: swarm init, memory, hooks, routing
- NEVER use CLI tools as a substitute for Task tool agents
## Support
- Documentation: https://github.com/ruvnet/claude-flow
- Issues: https://github.com/ruvnet/claude-flow/issues

Remember: **Claude Flow CLI coordinates, Claude Code Task tool creates!**
# important-instruction-reminders
Do what has been asked; nothing more, nothing less.
NEVER create files unless they're absolutely necessary for achieving your goal.
ALWAYS prefer editing an existing file to creating a new one.
NEVER proactively create documentation files (*.md) or README files. Only create documentation files if explicitly requested by the User.
Never save working files, text/mds and tests to the root folder.
## 🚨 SWARM EXECUTION RULES (CRITICAL)
1. **SPAWN IN BACKGROUND**: Use `run_in_background: true` for all agent Task calls
2. **SPAWN ALL AT ONCE**: Put ALL agent Task calls in ONE message for parallel execution
3. **TELL USER**: After spawning, list what each agent is doing (use emojis for clarity)
4. **STOP AND WAIT**: After spawning, STOP - do NOT add more tool calls or check status
5. **NO POLLING**: Never poll TaskOutput or check swarm status - trust agents to return
6. **SYNTHESIZE**: When agent results arrive, review ALL results before proceeding
7. **NO CONFIRMATION**: Don't ask "should I check?" - just wait for results
Example spawn message:
```
"I've launched 4 agents in background:
- 🔍 Researcher: [task]
- 💻 Coder: [task]
- 🧪 Tester: [task]
- 👀 Reviewer: [task]
Working in parallel - I'll synthesize when they complete."
```

# ADR-015: Public Dataset Strategy for Trained Pose Estimation Model
## Status
Accepted
## Context
The WiFi-DensePose system has a complete model architecture (`DensePoseHead`,
`ModalityTranslationNetwork`, `WiFiDensePoseRCNN`) and signal processing pipeline,
but no trained weights. Without a trained model, pose estimation produces random
outputs regardless of input quality.
Training requires paired data: simultaneous WiFi CSI captures alongside ground-truth
human pose annotations. Collecting this data from scratch requires months of effort
and specialized hardware (multiple WiFi nodes + camera + motion capture rig). Several
public datasets exist that can bootstrap training without custom collection.
### The Teacher-Student Constraint
The CMU "DensePose From WiFi" paper (2023) trains using a teacher-student approach:
a camera-based RGB pose model (e.g. Detectron2 DensePose) generates pseudo-labels
during training, so the WiFi model learns to replicate those outputs. At inference,
the camera is removed. This means any dataset that provides *either* ground-truth
pose annotations *or* synchronized RGB frames (from which a teacher can generate
labels) is sufficient for training.
### 56-Subcarrier Hardware Context
The system targets 56 subcarriers, which corresponds specifically to **Atheros 802.11n
chipsets on a 20 MHz channel** using the Atheros CSI Tool. No publicly available
dataset with paired pose annotations was collected at exactly 56 subcarriers:
| Hardware | Subcarriers | Datasets |
|----------|-------------|---------|
| Atheros CSI Tool (20 MHz) | **56** | None with pose labels |
| Atheros CSI Tool (40 MHz) | **114** | MM-Fi |
| Intel 5300 NIC (20 MHz) | **30** | Person-in-WiFi, Widar 3.0, Wi-Pose, XRF55 |
| Nexmon/Broadcom (80 MHz) | **242-256** | None with pose labels |
MM-Fi uses the same Atheros hardware family at 40 MHz, making 114→56 interpolation
physically meaningful (same chipset, different channel width).
## Decision
Use MM-Fi as the primary training dataset, supplemented by Wi-Pose (NjtechCVLab)
for additional diversity. XRF55 is downgraded to optional (Kinect labels need
post-processing). Teacher-student pipeline fills in DensePose UV labels where
only skeleton keypoints are available.
### Primary Dataset: MM-Fi
**Paper:** "MM-Fi: Multi-Modal Non-Intrusive 4D Human Dataset for Versatile Wireless
Sensing" (NeurIPS 2023 Datasets & Benchmarks)
**Repository:** https://github.com/ybhbingo/MMFi_dataset
**Size:** 40 subjects × 27 action classes × ~320,000 frames, 4 environments
**Modalities:** WiFi CSI, mmWave radar, LiDAR, RGB-D, IMU
**CSI format:** **1 TX × 3 RX antennas**, 114 subcarriers, 100 Hz sampling rate,
5 GHz 40 MHz (TP-Link N750 with Atheros CSI Tool), raw amplitude + phase
**Data tensor:** [3, 114, 10] per sample (antenna-pairs × subcarriers × time frames)
**Pose annotations:** 17-keypoint COCO skeleton in 3D + DensePose UV surface coords
**License:** CC BY-NC 4.0
**Why primary:** Largest public WiFi CSI + pose dataset; richest annotations (3D
keypoints + DensePose UV); same Atheros hardware family as target system; COCO
keypoints map directly to the `KeypointHead` output format; actively maintained
with NeurIPS 2023 benchmark status.
**Antenna correction:** MM-Fi uses 1 TX / 3 RX (3 antenna pairs), not 3×3.
The existing system targets 3×3 (ESP32 mesh). The 3 RX antennas match; the TX
difference means MM-Fi-trained weights will work but may benefit from fine-tuning
on data from a 3-TX setup.
### Secondary Dataset: Wi-Pose (NjtechCVLab)
**Paper:** CSI-Former (MDPI Entropy 2023) and related works
**Repository:** https://github.com/NjtechCVLab/Wi-PoseDataset
**Size:** 12 volunteers × 12 action classes × 166,600 packets
**CSI format:** 3 TX × 3 RX antennas, 30 subcarriers, 5 GHz, .mat format
**Pose annotations:** 18-keypoint AlphaPose skeleton (COCO-compatible subset)
**License:** Research use
**Why secondary:** 3×3 antenna array matches target ESP32 mesh hardware exactly;
fully public; adds 12 different subjects and environments not in MM-Fi.
**Note:** 30 subcarriers require zero-padding or interpolation to 56; 18→17
keypoint mapping drops one neck keypoint (index 1), compatible with COCO-17.
### Excluded / Deprioritized Datasets
| Dataset | Reason |
|---------|--------|
| RF-Pose / RF-Pose3D (MIT) | Custom FMCW radio, not 802.11n CSI; incompatible signal physics |
| Person-in-WiFi (CMU 2019) | Not publicly released (IRB restriction) |
| Person-in-WiFi 3D (CVPR 2024) | 30 subcarriers, Intel 5300; semi-public access |
| DensePose From WiFi (CMU) | Dataset not released; only paper + architecture |
| Widar 3.0 | Gesture labels only, no full-body pose keypoints |
| XRF55 | Activity labels primarily; Kinect pose requires email request; lower priority |
| UT-HAR, WiAR, SignFi | Activity/gesture labels only, no pose keypoints |
## Implementation Plan
### Phase 1: MM-Fi Loader (Rust `wifi-densepose-train` crate)
Implement `MmFiDataset` in Rust (`crates/wifi-densepose-train/src/dataset.rs`):
- Reads MM-Fi numpy .npy files: amplitude [N, 3, 3, 114] (antenna-pairs laid flat), phase [N, 3, 3, 114]
- Resamples from 114 → 56 subcarriers (linear interpolation via `subcarrier.rs`)
- Applies phase sanitization using SOTA algorithms from `wifi-densepose-signal` crate
- Returns typed `CsiSample` structs with amplitude, phase, keypoints, visibility
- Validation split: subjects 33–40 held out
### Phase 2: Wi-Pose Loader
Implement `WiPoseDataset` reading .mat files (via ndarray-based MATLAB reader or
pre-converted .npy). Subcarrier interpolation: 30 → 56 (zero-pad high frequencies
rather than interpolate, since 30-sub Intel data has different spectral occupancy
than 56-sub Atheros data).
### Phase 3: Teacher-Student DensePose Labels
For MM-Fi samples that provide 3D keypoints but not full DensePose UV maps:
- Run Detectron2 DensePose on paired RGB frames to generate `(part_labels, u_coords, v_coords)`
- Cache generated labels as .npy alongside original data
- This matches the training procedure in the CMU paper exactly
### Phase 4: Training Pipeline (Rust)
- **Model:** `WiFiDensePoseModel` (tch-rs, `crates/wifi-densepose-train/src/model.rs`)
- **Loss:** Keypoint heatmap (MSE) + DensePose part (cross-entropy) + UV (Smooth L1) + transfer (MSE)
- **Metrics:** PCK@0.2 + OKS with Hungarian min-cost assignment (`crates/wifi-densepose-train/src/metrics.rs`)
- **Optimizer:** Adam, lr=1e-3, step decay at epochs 40 and 80
- **Hardware:** Single GPU (RTX 3090 or A100); MM-Fi fits in ~50 GB disk
- **Checkpointing:** Save every epoch; keep best-by-validation-PCK
### Phase 5: Proof Verification
`verify-training` binary provides the "trust kill switch" for training:
- Fixed seed (MODEL_SEED=0, PROOF_SEED=42)
- 50 training steps on deterministic SyntheticDataset
- Verifies: loss decreases + SHA-256 of final weights matches stored hash
- EXIT 0 = PASS, EXIT 1 = FAIL, EXIT 2 = SKIP (no stored hash)
## Subcarrier Mismatch: MM-Fi (114) vs System (56)
MM-Fi captures 114 subcarriers at 5 GHz with 40 MHz bandwidth (Atheros CSI Tool).
The system is configured for 56 subcarriers (Atheros, 20 MHz). Resolution options:
1. **Interpolate MM-Fi → 56** (chosen for Phase 1): linear interpolation preserves
spectral envelope, fast, no architecture change needed
2. **Train at native 114**: change `CSIProcessor` config; requires re-running
`verify.py --generate-hash` to update proof hash; future option
3. **Collect native 56-sub data**: ESP32 mesh at 20 MHz; best for production
Option 1 unblocks training immediately. The Rust `subcarrier.rs` module handles
interpolation as a first-class operation with tests proving correctness.
## Consequences
**Positive:**
- Unblocks end-to-end training on real public data immediately
- MM-Fi's Atheros hardware family matches target system (same CSI Tool)
- 40 subjects × 27 actions provides reasonable diversity for first model
- Wi-Pose's 3×3 antenna setup is an exact hardware match for ESP32 mesh
- CC BY-NC license is compatible with research and internal use
- Rust implementation integrates natively with `wifi-densepose-signal` pipeline
**Negative:**
- CC BY-NC prohibits commercial deployment of weights trained solely on MM-Fi;
custom data collection required before commercial release
- MM-Fi is 1 TX / 3 RX; system targets 3 TX / 3 RX; fine-tuning needed
- 114→56 subcarrier interpolation loses frequency resolution; acceptable for v1
- MM-Fi captured in controlled lab environments; real-world accuracy will be lower
until fine-tuned on domain-specific data

# ADR-016: RuVector Integration for Training Pipeline
## Status
Accepted
## Context
The `wifi-densepose-train` crate (ADR-015) was initially implemented using
standard crates (`petgraph`, `ndarray`, custom signal processing). The ruvector
ecosystem provides published Rust crates with subpolynomial algorithms that
directly replace several components with superior implementations.
All ruvector crates are published at v2.0.4 on crates.io (confirmed) and their
source is available at https://github.com/ruvnet/ruvector.
### Available ruvector crates (all at v2.0.4, published on crates.io)
| Crate | Description | Default Features |
|-------|-------------|-----------------|
| `ruvector-mincut` | World's first subpolynomial dynamic min-cut | `exact`, `approximate` |
| `ruvector-attn-mincut` | Min-cut gating attention (graph-based alternative to softmax) | all modules |
| `ruvector-attention` | Geometric, graph, and sparse attention mechanisms | all modules |
| `ruvector-temporal-tensor` | Temporal tensor compression with tiered quantization | all modules |
| `ruvector-solver` | Sublinear-time sparse linear solvers O(log n) to O(√n) | `neumann`, `cg`, `forward-push` |
| `ruvector-core` | HNSW-indexed vector database core | v2.0.5 |
| `ruvector-math` | Optimal transport, information geometry | v2.0.4 |
### Verified API Details (from source inspection of github.com/ruvnet/ruvector)
#### ruvector-mincut
```rust
use ruvector_mincut::{MinCutBuilder, DynamicMinCut, MinCutResult, VertexId, Weight};
// Build a dynamic min-cut structure
let mut mincut = MinCutBuilder::new()
.exact() // or .approximate(0.1)
.with_edges(vec![(u: VertexId, v: VertexId, w: Weight)]) // (u32, u32, f64) tuples
.build()
.expect("Failed to build");
// Subpolynomial O(n^{o(1)}) amortized dynamic updates
mincut.insert_edge(u, v, weight) -> Result<f64> // new cut value
mincut.delete_edge(u, v) -> Result<f64> // new cut value
// Queries
mincut.min_cut_value() -> f64
mincut.min_cut() -> MinCutResult // includes partition
mincut.partition() -> (Vec<VertexId>, Vec<VertexId>) // S and T sets
mincut.cut_edges() -> Vec<Edge> // edges crossing the cut
// Note: VertexId = u64 (not u32); Edge has fields { source: u64, target: u64, weight: f64 }
```
`MinCutResult` contains:
- `value: f64` — minimum cut weight
- `is_exact: bool`
- `approximation_ratio: f64`
- `partition: Option<(Vec<VertexId>, Vec<VertexId>)>` — S and T node sets
#### ruvector-attn-mincut
```rust
use ruvector_attn_mincut::{attn_mincut, attn_softmax, AttentionOutput, MinCutConfig};
// Min-cut gated attention (drop-in for softmax attention)
// Q, K, V are all flat &[f32] with shape [seq_len, d]
let output: AttentionOutput = attn_mincut(
q: &[f32], // queries: flat [seq_len * d]
k: &[f32], // keys: flat [seq_len * d]
v: &[f32], // values: flat [seq_len * d]
d: usize, // feature dimension
seq_len: usize, // number of tokens / antenna paths
lambda: f32, // min-cut threshold (larger = more pruning)
tau: usize, // temporal hysteresis window
eps: f32, // numerical epsilon
) -> AttentionOutput;
// AttentionOutput
pub struct AttentionOutput {
pub output: Vec<f32>, // attended values [seq_len * d]
pub gating: GatingResult, // which edges were kept/pruned
}
// Baseline softmax attention for comparison
let output: Vec<f32> = attn_softmax(q, k, v, d, seq_len);
```
**Use case in wifi-densepose-train**: In `ModalityTranslator`, treat the
`T * n_tx * n_rx` antenna×time paths as `seq_len` tokens and the `n_sc`
subcarriers as feature dimension `d`. Apply `attn_mincut` to gate irrelevant
antenna-pair correlations before passing to FC layers.
#### ruvector-solver (NeumannSolver)
```rust
use ruvector_solver::neumann::NeumannSolver;
use ruvector_solver::types::CsrMatrix;
use ruvector_solver::traits::SolverEngine;
// Build sparse matrix from COO entries
let matrix = CsrMatrix::<f32>::from_coo(rows, cols, vec![
(row: usize, col: usize, val: f32), ...
]);
// Solve Ax = b in O(√n) for sparse systems
let solver = NeumannSolver::new(tolerance: f64, max_iterations: usize);
let result = solver.solve(&matrix, rhs: &[f32]) -> Result<SolverResult, SolverError>;
// SolverResult
result.solution: Vec<f32> // solution vector x
result.residual_norm: f64 // ||b - Ax||
result.iterations: usize // number of iterations used
```
**Use case in wifi-densepose-train**: In `subcarrier.rs`, model the 114→56
subcarrier resampling as a sparse regularized least-squares problem `A·x ≈ b`
where `A` is a sparse basis-function matrix (physically motivated by multipath
propagation model: each target subcarrier is a sparse combination of adjacent
source subcarriers). Gives O(√n) vs O(n) for n=114 subcarriers.
#### ruvector-temporal-tensor
```rust
use ruvector_temporal_tensor::{TemporalTensorCompressor, TierPolicy};
use ruvector_temporal_tensor::segment;
// Create compressor for `element_count` f32 elements per frame
let mut comp = TemporalTensorCompressor::new(
TierPolicy::default(), // configures hot/warm/cold thresholds
element_count: usize, // n_tx * n_rx * n_sc (elements per CSI frame)
id: u64, // tensor identity (0 for amplitude, 1 for phase)
);
// Mark access recency (drives tier selection):
// hot = accessed within last few timestamps → 8-bit (~4x compression)
// warm = moderately recent → 5 or 7-bit (~4.6–6.4x)
// cold = rarely accessed → 3-bit (~10.67x)
comp.set_access(timestamp: u64, tensor_id: u64);
// Compress frames into a byte segment
let mut segment_buf: Vec<u8> = Vec::new();
comp.push_frame(frame: &[f32], timestamp: u64, &mut segment_buf);
comp.flush(&mut segment_buf); // flush current partial segment
// Decompress
let mut decoded: Vec<f32> = Vec::new();
segment::decode(&segment_buf, &mut decoded); // all frames
segment::decode_single_frame(&segment_buf, frame_index: usize) -> Option<Vec<f32>>;
segment::compression_ratio(&segment_buf) -> f64;
```
**Use case in wifi-densepose-train**: In `dataset.rs`, buffer CSI frames in
`TemporalTensorCompressor` to reduce memory footprint by 50–75%. The CSI window
contains `window_frames` (default 100) frames per sample; hot frames (recent)
stay at f32 fidelity, cold frames (older) are aggressively quantized.
#### ruvector-attention
```rust
use ruvector_attention::{
attention::ScaledDotProductAttention,
traits::Attention,
};
let attention = ScaledDotProductAttention::new(d: usize); // feature dim
// Compute attention: q is [d], keys and values are Vec<&[f32]>
let output: Vec<f32> = attention.compute(
query: &[f32], // [d]
keys: &[&[f32]], // n_nodes × [d]
values: &[&[f32]], // n_nodes × [d]
) -> Result<Vec<f32>>;
```
**Use case in wifi-densepose-train**: In `model.rs` spatial decoder, replace the
standard Conv2D upsampling pass with graph-based spatial attention among spatial
locations, where nodes represent spatial grid points and edges connect neighboring
antenna footprints.
---
## Decision
Integrate ruvector crates into `wifi-densepose-train` at five integration points:
### 1. `ruvector-mincut` → `metrics.rs` (replaces petgraph Hungarian for multi-frame)
**Before:** O(n³) Kuhn-Munkres via DFS augmenting paths using `petgraph::DiGraph`,
single-frame only (no state across frames).
**After:** `DynamicPersonMatcher` struct wrapping `ruvector_mincut::DynamicMinCut`.
Maintains the bipartite assignment graph across frames using subpolynomial updates:
- `insert_edge(pred_id, gt_id, oks_cost)` when new person detected
- `delete_edge(pred_id, gt_id)` when person leaves scene
- `partition()` returns S/T split → `cut_edges()` returns the matched pred→gt pairs
**Performance:** O(n^{1.5} log n) amortized update vs O(n³) rebuild per frame.
Critical for >3 person scenarios and video tracking (frame-to-frame updates).
The original `hungarian_assignment` function is **kept** for single-frame static
matching (used in proof verification for determinism).
### 2. `ruvector-attn-mincut` → `model.rs` (replaces flat MLP fusion in ModalityTranslator)
**Before:** Amplitude/phase FC encoders → concatenate [B, 512] → fuse Linear → ReLU.
**After:** Treat the `n_ant = T * n_tx * n_rx` antenna×time paths as `seq_len`
tokens and `n_sc` subcarriers as feature dimension `d`. Apply `attn_mincut` to
gate irrelevant antenna-pair correlations:
```rust
// In ModalityTranslator::forward_t:
// amp/ph tensors: [B, n_ant, n_sc] → convert to Vec<f32>
// Apply attn_mincut with seq_len=n_ant, d=n_sc, lambda=0.3
// → attended output [B, n_ant, n_sc] → flatten → FC layers
```
**Benefit:** Automatic antenna-path selection without explicit learned masks;
min-cut gating is more computationally principled than learned gates.
### 3. `ruvector-temporal-tensor` → `dataset.rs` (CSI temporal compression)
**Before:** Raw CSI windows stored as full f32 `Array4<f32>` in memory.
**After:** `CompressedCsiBuffer` struct backed by `TemporalTensorCompressor`.
Tiered quantization based on frame access recency:
- Hot frames (last 10): f32 equivalent (8-bit quant ≈ 4× smaller than f32)
- Warm frames (11–50): 5/7-bit quantization
- Cold frames (>50): 3-bit (10.67× smaller)
Encode on `push_frame`, decode on `get(idx)` for transparent access.
**Benefit:** 50–75% memory reduction for the default 100-frame temporal window;
allows 2–4× larger batch sizes on constrained hardware.
### 4. `ruvector-solver` → `subcarrier.rs` (phase sanitization)
**Before:** Linear interpolation across subcarriers using precomputed (i0, i1, frac) tuples.
**After:** `NeumannSolver` for sparse regularized least-squares subcarrier
interpolation. The CSI spectrum is modeled as a sparse combination of Fourier
basis functions (physically motivated by multipath propagation):
```rust
// A = sparse basis matrix [target_sc, src_sc] (Gaussian or sinc basis)
// b = source CSI values [src_sc]
// Solve: A·x ≈ b via NeumannSolver(tolerance=1e-5, max_iter=500)
// x = interpolated values at target subcarrier positions
```
**Benefit:** O(√n) vs O(n) for n=114 source subcarriers; more accurate at
subcarrier boundaries than linear interpolation.
### 5. `ruvector-attention` → `model.rs` (spatial decoder)
**Before:** Standard ConvTranspose2D upsampling in `KeypointHead` and `DensePoseHead`.
**After:** `ScaledDotProductAttention` applied to spatial feature nodes.
Each spatial location [H×W] becomes a token; attention captures long-range
spatial dependencies between antenna footprint regions:
```rust
// feature map: [B, C, H, W] → flatten to [B, H*W, C]
// For each batch: compute attention among H*W spatial nodes
// → reshape back to [B, C, H, W]
```
**Benefit:** Captures long-range spatial dependencies missed by local convolutions;
important for multi-person scenarios.

## Implementation Plan
### Files modified
| File | Change |
|------|--------|
| `Cargo.toml` (workspace + crate) | Add ruvector-mincut, ruvector-attn-mincut, ruvector-temporal-tensor, ruvector-solver, ruvector-attention = "2.0.4" |
| `metrics.rs` | Add `DynamicPersonMatcher` wrapping `ruvector_mincut::DynamicMinCut`; keep `hungarian_assignment` for deterministic proof |
| `model.rs` | Add `attn_mincut` bridge in `ModalityTranslator::forward_t`; add `ScaledDotProductAttention` in spatial heads |
| `dataset.rs` | Add `CompressedCsiBuffer` backed by `TemporalTensorCompressor`; `MmFiDataset` uses it |
| `subcarrier.rs` | Add `interpolate_subcarriers_sparse` using `NeumannSolver`; keep `interpolate_subcarriers` as fallback |
### Files unchanged
`config.rs`, `losses.rs`, `trainer.rs`, `proof.rs`, `error.rs` — no change needed.
### Feature gating
All ruvector integrations are **always-on** (not feature-gated). The ruvector
crates are pure Rust with no C FFI, so they add no platform constraints.

## Consequences
**Positive:**
- Subpolynomial O(n^{1.5} log n) dynamic min-cut for multi-person tracking
- Min-cut gated attention is physically motivated for CSI antenna arrays
- 50–75% memory reduction from temporal quantization
- Sparse least-squares interpolation is physically principled vs linear

**Negative:**
- Additional compile-time dependencies (ruvector crates)
- `attn_mincut` requires tensor↔Vec<f32> conversion overhead per batch element

- `NeumannSolver` requires diagonally dominant matrices; a sparse Tikhonov
regularization term (λI) is added to ensure convergence

# ADR-017: RuVector Integration for Signal Processing and MAT Crates
## Status
Accepted
## Date
2026-02-28
## Context
ADR-016 integrated all five published ruvector v2.0.4 crates into the
`wifi-densepose-train` crate (model.rs, dataset.rs, subcarrier.rs, metrics.rs).
Two production crates that pre-date ADR-016 remain without ruvector integration
despite having concrete, high-value integration points:
1. **`wifi-densepose-signal`** — SOTA signal processing algorithms (ADR-014):
conjugate multiplication, Hampel filter, Fresnel zone breathing model, CSI
spectrogram, subcarrier sensitivity selection, Body Velocity Profile (BVP).
These algorithms perform independent element-wise operations or brute-force
exhaustive search without subpolynomial optimization.
2. **`wifi-densepose-mat`** — Disaster detection (ADR-001): multi-AP
triangulation, breathing/heartbeat waveform detection, triage classification.
Time-series data is uncompressed and localization uses closed-form geometry
without iterative system solving.
Additionally, ADR-002's dependency strategy references fictional crate names
(`ruvector-core`, `ruvector-data-framework`, `ruvector-consensus`,
`ruvector-wasm`) at non-existent version `"0.1"`. ADR-016 confirmed the actual
published crates at v2.0.4 and these must be used instead.
### Verified Published Crates (v2.0.4)
From source inspection of github.com/ruvnet/ruvector and crates.io:

### Integration 1: Subcarrier Sensitivity Selection via DynamicMinCut
**File:** `wifi-densepose-signal/src/subcarrier_selection.rs`
**Crate:** `ruvector-mincut`
**Current approach:** Rank all subcarriers by `variance_motion / variance_static`
ratio, take top-K by sorting. O(n log n) sort, static partition.
**ruvector integration:** Build a similarity graph where subcarriers are vertices
and edges encode variance-ratio similarity (|sensitivity_i − sensitivity_j|^−1).
`DynamicMinCut` finds the minimum bisection separating high-sensitivity
(motion-responsive) from low-sensitivity (noise-dominated) subcarriers. As new
static/motion measurements arrive, `insert_edge`/`delete_edge` incrementally
update the partition in O(n^1.5 log n) amortized — no full re-sort needed.
```rust
use ruvector_mincut::{DynamicMinCut, MinCutBuilder};
/// Partition subcarriers into sensitive/insensitive groups via min-cut.
/// Returns (sensitive_indices, insensitive_indices).
pub fn mincut_subcarrier_partition(
sensitivity: &[f32],
) -> (Vec<usize>, Vec<usize>) {
let n = sensitivity.len();
// Build fully-connected similarity graph (prune edges < threshold)
let threshold = 0.1_f64;
let mut edges = Vec::new();
for i in 0..n {
for j in (i + 1)..n {
let diff = (sensitivity[i] - sensitivity[j]).abs() as f64;
let weight = if diff > 1e-9 { 1.0 / diff } else { 1e6 };
if weight > threshold {
edges.push((i as u64, j as u64, weight));
}
}
}
let mc = MinCutBuilder::new().exact().with_edges(edges).build();
let (side_a, side_b) = mc.partition();
// side with higher mean sensitivity = sensitive
let mean_a: f32 = side_a.iter().map(|&i| sensitivity[i as usize]).sum::<f32>()
/ side_a.len() as f32;
let mean_b: f32 = side_b.iter().map(|&i| sensitivity[i as usize]).sum::<f32>()
/ side_b.len() as f32;
if mean_a >= mean_b {
(side_a.into_iter().map(|x| x as usize).collect(),
side_b.into_iter().map(|x| x as usize).collect())
} else {
(side_b.into_iter().map(|x| x as usize).collect(),
side_a.into_iter().map(|x| x as usize).collect())
}
}
```
**Advantage:** Incremental updates as the environment changes (furniture moved,
new occupant) do not require re-ranking all subcarriers. Dynamic partition tracks
changing sensitivity in O(n^1.5 log n) vs O(n^2) re-scan.
---
### Integration 2: Attention-Gated CSI Spectrogram
**File:** `wifi-densepose-signal/src/spectrogram.rs`
**Crate:** `ruvector-attn-mincut`
**Current approach:** Compute STFT per subcarrier independently, stack into 2D
matrix [freq_bins × time_frames]. All bins weighted equally for downstream CNN.
**ruvector integration:** After STFT, treat each time frame as a sequence token
(d = n_freq_bins, seq_len = n_time_frames). Apply `attn_mincut` to gate which
time-frequency cells contribute to the spectrogram output — suppressing noise
frames and multipath artifacts while amplifying body-motion periods.
```rust
use ruvector_attn_mincut::attn_mincut;
/// Apply attention gating to a computed spectrogram.
/// spectrogram: [n_freq_bins × n_time_frames] row-major f32
pub fn gate_spectrogram(
spectrogram: &[f32],
n_freq: usize,
n_time: usize,
lambda: f32, // 0.1 = mild gating, 0.5 = aggressive
) -> Vec<f32> {
// Q = K = V = spectrogram (self-attention over time frames)
let out = attn_mincut(
spectrogram, spectrogram, spectrogram,
n_freq, // d = feature dimension (freq bins)
n_time, // seq_len = number of time frames
lambda,
/*tau=*/ 2,
/*eps=*/ 1e-7,
);
out.output
}
```
**Advantage:** Self-attention + mincut identifies coherent temporal segments
(body motion intervals) and gates out uncorrelated frames (ambient noise, transient
interference). Lambda tunes the gating strength without requiring separate
denoising or temporal smoothing steps.
---
### Integration 3: Cross-Subcarrier BVP Attention
**File:** `wifi-densepose-signal/src/bvp.rs`
**Crate:** `ruvector-attention`
**Current approach:** Aggregate Body Velocity Profile by summing STFT magnitudes
uniformly across all subcarriers: `BVP[v,t] = Σ_k |STFT_k[v,t]|`. Equal
weighting means insensitive subcarriers dilute the velocity estimate.
**ruvector integration:** Use `ScaledDotProductAttention` to compute a
weighted aggregation across subcarriers. Each subcarrier contributes a key
(its sensitivity profile) and value (its STFT row). The query is the current
velocity bin. Attention weights automatically emphasize subcarriers that are
responsive to the queried velocity range.
```rust
use ruvector_attention::ScaledDotProductAttention;
/// Compute attention-weighted BVP aggregation across subcarriers.
/// stft_rows: Vec of n_subcarriers rows, each [n_velocity_bins] f32
/// sensitivity: sensitivity score per subcarrier [n_subcarriers] f32
pub fn attention_weighted_bvp(
stft_rows: &[Vec<f32>],
sensitivity: &[f32],
n_velocity_bins: usize,
) -> Vec<f32> {
let d = n_velocity_bins;
let attn = ScaledDotProductAttention::new(d);
// Mean sensitivity row as query (overall body motion profile)
let query: Vec<f32> = (0..d).map(|v| {
stft_rows.iter().zip(sensitivity.iter())
.map(|(row, &s)| row[v] * s)
.sum::<f32>()
/ sensitivity.iter().sum::<f32>()
}).collect();
// Keys = STFT rows (each subcarrier's velocity profile)
// Values = STFT rows (same, weighted by attention)
let keys: Vec<&[f32]> = stft_rows.iter().map(|r| r.as_slice()).collect();
let values: Vec<&[f32]> = stft_rows.iter().map(|r| r.as_slice()).collect();
attn.compute(&query, &keys, &values)
.unwrap_or_else(|_| vec![0.0; d])
}
```
**Advantage:** Replaces uniform sum with sensitivity-aware weighting. Subcarriers
in multipath nulls or noise-dominated frequency bands receive low attention weight
automatically, without requiring manual selection or a separate sensitivity step.
---
### Integration 4: Fresnel Zone Geometry System via NeumannSolver
**File:** `wifi-densepose-signal/src/fresnel.rs`
**Crate:** `ruvector-solver`
**Current approach:** Closed-form Fresnel zone radius formula assuming known
TX-RX-body geometry. In practice, exact distances d1 (TX→body) and d2
(body→RX) are unknown — only the TX-RX straight-line distance D is known from
AP placement.
**ruvector integration:** When multiple subcarriers observe different Fresnel
zone crossings at the same chest displacement, we can solve for the unknown
geometry (d1, d2, Δd) using the over-determined linear system from multiple
observations. `NeumannSolver` handles the sparse normal equations efficiently.
```rust
use ruvector_solver::neumann::NeumannSolver;
use ruvector_solver::types::CsrMatrix;
/// Estimate TX-body and body-RX distances from multi-subcarrier Fresnel observations.
/// observations: Vec of (wavelength_m, observed_amplitude_variation)
/// Returns (d1_estimate_m, d2_estimate_m)
pub fn solve_fresnel_geometry(
observations: &[(f32, f32)],
d_total: f32, // Known TX-RX straight-line distance in metres
) -> Option<(f32, f32)> {
let n = observations.len();
if n < 3 { return None; }
// System: A·[d1, d2]^T = b
// From Fresnel: A_k = |sin(2π·2·Δd / λ_k)|, observed ~ A_k
// Linearize: use log-magnitude ratios as rows
// Normal equations: (A^T A + λI) x = A^T b
let lambda_reg = 0.05_f32;
let mut coo = Vec::new();
let mut rhs = vec![0.0_f32; 2];
for (k, &(wavelength, amplitude)) in observations.iter().enumerate() {
// Row k: [1/wavelength, -1/wavelength] · [d1; d2] ≈ log(amplitude + 1)
let coeff = 1.0 / wavelength;
coo.push((k, 0, coeff));
coo.push((k, 1, -coeff));
let _ = amplitude; // used implicitly via b vector
}
// Build normal equations
let ata_csr = CsrMatrix::<f32>::from_coo(2, 2, vec![
(0, 0, lambda_reg + observations.iter().map(|(w, _)| 1.0 / (w * w)).sum::<f32>()),
(1, 1, lambda_reg + observations.iter().map(|(w, _)| 1.0 / (w * w)).sum::<f32>()),
]);
let atb: Vec<f32> = vec![
observations.iter().map(|(w, a)| a / w).sum::<f32>(),
-observations.iter().map(|(w, a)| a / w).sum::<f32>(),
];
let solver = NeumannSolver::new(1e-5, 300);
match solver.solve(&ata_csr, &atb) {
Ok(result) => {
let d1 = result.solution[0].abs().clamp(0.1, d_total - 0.1);
let d2 = (d_total - d1).clamp(0.1, d_total - 0.1);
Some((d1, d2))
}
Err(_) => None,
}
}
```
**Advantage:** Converts the Fresnel model from a single fixed-geometry formula
into a data-driven geometry estimator. With 3+ observations (subcarriers at
different frequencies), NeumannSolver converges in O(√n) iterations — critical
for real-time breathing detection at 100 Hz.
---
### Integration 5: Multi-AP Triangulation via NeumannSolver
**File:** `wifi-densepose-mat/src/localization/triangulation.rs`
**Crate:** `ruvector-solver`
**Current approach:** Multi-AP localization uses pairwise TDoA (Time Difference
of Arrival) converted to hyperbolic equations. Solving N-AP systems requires
linearization and least-squares, currently implemented as brute-force normal
equations via Gaussian elimination (O(n^3)).
**ruvector integration:** The linearized TDoA system is sparse (each measurement
involves 2 APs, not all N). `CsrMatrix::from_coo` + `NeumannSolver` solves the
sparse normal equations in O(√nnz) where nnz = number of non-zeros ≪ N^2.
```rust
use ruvector_solver::neumann::NeumannSolver;
use ruvector_solver::types::CsrMatrix;
/// Solve multi-AP TDoA survivor localization.
/// tdoa_measurements: Vec of (ap_i_idx, ap_j_idx, tdoa_seconds)
/// ap_positions: Vec of (x, y) metre positions
/// Returns estimated (x, y) survivor position.
pub fn solve_triangulation(
tdoa_measurements: &[(usize, usize, f32)],
ap_positions: &[(f32, f32)],
) -> Option<(f32, f32)> {
let n_meas = tdoa_measurements.len();
if n_meas < 3 { return None; }
const C: f32 = 3e8_f32; // speed of light
let mut coo = Vec::new();
let mut b = vec![0.0_f32; n_meas];
// Linearize: subtract reference AP from each TDoA equation
let (x_ref, y_ref) = ap_positions[0];
for (row, &(i, j, tdoa)) in tdoa_measurements.iter().enumerate() {
let (xi, yi) = ap_positions[i];
let (xj, yj) = ap_positions[j];
// (xi - xj)·x + (yi - yj)·y ≈ (d_ref_i - d_ref_j + C·tdoa) / 2
coo.push((row, 0, xi - xj));
coo.push((row, 1, yi - yj));
b[row] = C * tdoa / 2.0
+ ((xi * xi - xj * xj) + (yi * yi - yj * yj)) / 2.0
- x_ref * (xi - xj) - y_ref * (yi - yj);
}
// Normal equations: (A^T A + λI) x = A^T b
let lambda = 0.01_f32;
let ata = CsrMatrix::<f32>::from_coo(2, 2, vec![
(0, 0, lambda + coo.iter().filter(|e| e.1 == 0).map(|e| e.2 * e.2).sum::<f32>()),
(0, 1, coo.iter().filter(|e| e.1 == 0).zip(coo.iter().filter(|e| e.1 == 1)).map(|(a, b2)| a.2 * b2.2).sum::<f32>()),
(1, 0, coo.iter().filter(|e| e.1 == 1).zip(coo.iter().filter(|e| e.1 == 0)).map(|(a, b2)| a.2 * b2.2).sum::<f32>()),
(1, 1, lambda + coo.iter().filter(|e| e.1 == 1).map(|e| e.2 * e.2).sum::<f32>()),
]);
let atb = vec![
coo.iter().filter(|e| e.1 == 0).zip(b.iter()).map(|(e, &bi)| e.2 * bi).sum::<f32>(),
coo.iter().filter(|e| e.1 == 1).zip(b.iter()).map(|(e, &bi)| e.2 * bi).sum::<f32>(),
];
NeumannSolver::new(1e-5, 500)
.solve(&ata, &atb)
.ok()
.map(|r| (r.solution[0], r.solution[1]))
}
```
**Advantage:** For a disaster site with 5–20 APs, the TDoA system has N×(N-1)/2
= 10–190 measurements but only 2 unknowns (x, y). The normal equations are 2×2
regardless of N. NeumannSolver converges in O(1) iterations for well-conditioned
2×2 systems — eliminating Gaussian elimination overhead.
---
### Integration 6: Breathing Waveform Compression
**File:** `wifi-densepose-mat/src/detection/breathing.rs`
**Crate:** `ruvector-temporal-tensor`
**Current approach:** Breathing detector maintains an in-memory ring buffer of
recent CSI amplitude samples across subcarriers × time. For a 60-second window
at 100 Hz with 56 subcarriers: 60 × 100 × 56 × 4 bytes = **13.4 MB per zone**.
With 16 concurrent zones: **214 MB just for breathing buffers**.
**ruvector integration:** `TemporalTensorCompressor` with tiered quantization
(8-bit hot / 5-7-bit warm / 3-bit cold) compresses the breathing waveform buffer
by 50–75%:
```rust
use ruvector_temporal_tensor::{TemporalTensorCompressor, TierPolicy};
use ruvector_temporal_tensor::segment;
pub struct CompressedBreathingBuffer {
compressor: TemporalTensorCompressor,
encoded: Vec<u8>,
n_subcarriers: usize,
frame_count: u64,
}
impl CompressedBreathingBuffer {
pub fn new(n_subcarriers: usize, zone_id: u64) -> Self {
Self {
compressor: TemporalTensorCompressor::new(
TierPolicy::default(),
n_subcarriers,
zone_id,
),
encoded: Vec::new(),
n_subcarriers,
frame_count: 0,
}
}
pub fn push_frame(&mut self, amplitudes: &[f32]) {
self.compressor.push_frame(amplitudes, self.frame_count, &mut self.encoded);
self.frame_count += 1;
}
pub fn flush(&mut self) {
self.compressor.flush(&mut self.encoded);
}
/// Decode all frames for frequency analysis.
pub fn to_vec(&self) -> Vec<f32> {
let mut out = Vec::new();
segment::decode(&self.encoded, &mut out);
out
}
/// Get single frame for real-time display.
pub fn get_frame(&self, idx: usize) -> Option<Vec<f32>> {
segment::decode_single_frame(&self.encoded, idx)
}
}
```
**Memory reduction:** 13.4 MB/zone → 3.4–6.7 MB/zone. 16 zones: 54–107 MB
instead of 214 MB. Disaster response hardware (Raspberry Pi 4: 4–8 GB) can
handle 2–4× more concurrent zones.
---
### Integration 7: Heartbeat Micro-Doppler Compression
**File:** `wifi-densepose-mat/src/detection/heartbeat.rs`
**Crate:** `ruvector-temporal-tensor`
**Current approach:** Heartbeat detection uses micro-Doppler spectrograms:
sliding STFT of CSI amplitude time-series. Each zone stores a spectrogram of
shape [n_freq_bins=128, n_time=600] (60 seconds at 10 Hz output rate):
128 × 600 × 4 bytes = **307 KB per zone**. With 16 zones: 4.9 MB — acceptable,
but heartbeat spectrograms are the most access-intensive (queried at every triage
update).
**ruvector integration:** `TemporalTensorCompressor` stores the spectrogram rows
as temporal frames (each row = one frequency bin's time-evolution). Hot tier
(recent 10 seconds) at 8-bit, warm (10–30 sec) at 5-bit, cold (>30 sec) at 3-bit.
Recent heartbeat cycles remain high-fidelity; historical data is compressed 5x:
```rust
pub struct CompressedHeartbeatSpectrogram {
/// One compressor per frequency bin
bin_buffers: Vec<TemporalTensorCompressor>,
encoded: Vec<Vec<u8>>,
n_freq_bins: usize,
frame_count: u64,
}
impl CompressedHeartbeatSpectrogram {
pub fn new(n_freq_bins: usize) -> Self {
let bin_buffers: Vec<_> = (0..n_freq_bins)
.map(|i| TemporalTensorCompressor::new(TierPolicy::default(), 1, i as u64))
.collect();
let encoded = vec![Vec::new(); n_freq_bins];
Self { bin_buffers, encoded, n_freq_bins, frame_count: 0 }
}
/// Push one column of the spectrogram (one time step, all frequency bins).
pub fn push_column(&mut self, column: &[f32]) {
for (i, (&val, buf)) in column.iter().zip(self.bin_buffers.iter_mut()).enumerate() {
buf.push_frame(&[val], self.frame_count, &mut self.encoded[i]);
}
self.frame_count += 1;
}
/// Extract heartbeat frequency band power (0.8–1.5 Hz) from recent frames.
pub fn heartbeat_band_power(&self, low_bin: usize, high_bin: usize) -> f32 {
(low_bin..=high_bin.min(self.n_freq_bins - 1))
.map(|b| {
let mut out = Vec::new();
segment::decode(&self.encoded[b], &mut out);
out.iter().rev().take(100).map(|x| x * x).sum::<f32>()
})
.sum::<f32>()
/ (high_bin - low_bin + 1) as f32
}
}
```

## Dependency Changes Required
Add to `rust-port/wifi-densepose-rs/Cargo.toml` workspace (already present from ADR-016):
```toml
ruvector-mincut = "2.0.4" # already present
ruvector-attn-mincut = "2.0.4" # already present
ruvector-temporal-tensor = "2.0.4" # already present
ruvector-solver = "2.0.4" # already present
ruvector-attention = "2.0.4" # already present
```
Add to `wifi-densepose-signal/Cargo.toml` and `wifi-densepose-mat/Cargo.toml`:
```toml
[dependencies]
ruvector-mincut = { workspace = true }
ruvector-attn-mincut = { workspace = true }
ruvector-temporal-tensor = { workspace = true }
ruvector-solver = { workspace = true }
ruvector-attention = { workspace = true }
```
## Correction to ADR-002 Dependency Strategy
ADR-002's dependency strategy section specifies non-existent crates:
```toml
# WRONG (ADR-002 original — these crates do not exist at crates.io)
ruvector-core = { version = "0.1", features = ["hnsw", "sona", "gnn"] }
ruvector-data-framework = { version = "0.1", features = ["rvf", "witness", "crypto"] }
ruvector-consensus = { version = "0.1", features = ["raft"] }
ruvector-wasm = { version = "0.1", features = ["edge-runtime"] }
```
The correct published crates (verified at crates.io, source at github.com/ruvnet/ruvector):
```toml
# CORRECT (as of 2026-02-28, all at v2.0.4)
ruvector-mincut = "2.0.4" # Dynamic min-cut, O(n^1.5 log n) updates
ruvector-attn-mincut = "2.0.4" # Attention + mincut gating
ruvector-temporal-tensor = "2.0.4" # Tiered temporal compression
ruvector-solver = "2.0.4" # NeumannSolver, sublinear convergence
ruvector-attention = "2.0.4" # ScaledDotProductAttention
```
The RVF cognitive container format (ADR-003), HNSW search (ADR-004), SONA
self-learning (ADR-005), GNN patterns (ADR-006), post-quantum crypto (ADR-007),
Raft consensus (ADR-008), and WASM edge runtime (ADR-009) described in ADR-002
are architectural capabilities internal to ruvector but not exposed as separate
published crates at v2.0.4. Those ADRs remain as forward-looking architectural
guidance; their implementation paths will use the five published crates as
building blocks where applicable.
## Implementation Priority
| Priority | Integration | Rationale |
|---|---|---|
| P1 | Breathing + heartbeat compression (MAT) | Memory-critical for 16-zone disaster deployments |
| P1 | Multi-AP triangulation (MAT) | Safety-critical accuracy improvement |
| P2 | Subcarrier selection via DynamicMinCut | Enables dynamic environment adaptation |
| P2 | BVP attention aggregation | Direct accuracy improvement for activity classification |
| P3 | Spectrogram attention gating | Reduces CNN input noise; requires CNN retraining |
| P3 | Fresnel geometry system | Improves breathing detection in unknown geometries |
## Consequences
### Positive
- Consistent ruvector integration across all production crates (train, signal, MAT)
- 50–75% memory reduction in disaster detection enables 2–4× more concurrent zones
- Dynamic subcarrier partitioning adapts to environment changes without manual tuning
- Attention-weighted BVP reduces velocity estimation error from insensitive subcarriers
- NeumannSolver triangulation is O(1) in AP count (always solves 2×2 system)
### Negative
- ruvector crates operate on `&[f32]` CPU slices; MAT and signal crates must
bridge from their native types (ndarray, complex numbers)
- `ruvector-temporal-tensor` compression is lossy; heartbeat amplitude values
may lose fine-grained detail in warm/cold tiers (mitigated by hot-tier recency)
- Subcarrier selection via DynamicMinCut assumes a bipartite-like partition;
environments with 3+ distinct subcarrier groups may need multi-way cut extension

# ADR-018: ESP32 Development Implementation Path
## Status
Proposed
## Date
2026-02-28
## Context
ADR-012 established the ESP32 CSI Sensor Mesh architecture: hardware rationale, firmware file structure, `csi_feature_frame_t` C struct, aggregator design, clock-drift handling via feature-level fusion, and a $54 starter BOM. That ADR answers *what* to build and *why*.
This ADR answers *how* to build it — the concrete development sequence, the specific integration points in existing code, and how to test each layer before hardware is in hand.

### Binary Frame Format (implemented in `esp32_parser.rs`)
```
Offset Size Field
0 4 Magic: 0xC5110001 (LE)
4 1 Node ID (0-255)
5 1 Number of antennas
6 2 Number of subcarriers (LE u16)
8 4 Frequency Hz (LE u32, e.g. 2412 for 2.4 GHz ch1)
12 4 Sequence number (LE u32)
16 1 RSSI (i8, dBm)
17 1 Noise floor (i8, dBm)
18 2 Reserved (zero)
20 N*2 I/Q pairs: (i8, i8) per subcarrier, repeated per antenna
```
Total frame size: 20 + (n_antennas × n_subcarriers × 2) bytes.
For 3 antennas, 56 subcarriers: 20 + 336 = 356 bytes per frame.
The firmware must write frames in this exact format. The parser already validates magic, bounds-checks `n_subcarriers` (≤512), and resyncs the stream on magic search for `parse_stream()`.
## Decision
We will implement the ESP32 development stack in four sequential layers, each independently testable before hardware is available.
### Layer 1 — ESP-IDF Firmware (`firmware/esp32-csi-node/`)
Implement the C firmware project per the file structure in ADR-012. Key design decisions deferred from ADR-012:
**CSI callback → frame serializer:**
```c
// main/csi_collector.c
static void csi_data_callback(void *ctx, wifi_csi_info_t *info) {
if (!info || !info->buf) return;
// Write binary frame header (20 bytes, little-endian)
uint8_t frame[FRAME_MAX_BYTES];
uint32_t magic = 0xC5110001;
memcpy(frame + 0, &magic, 4);
frame[4] = g_node_id;
frame[5] = info->rx_ctrl.ant; // antenna index (1 for ESP32 single-antenna)
uint16_t n_sub = info->len / 2; // len = n_subcarriers * 2 (I + Q bytes)
memcpy(frame + 6, &n_sub, 2);
uint32_t freq_mhz = g_channel_freq_mhz;
memcpy(frame + 8, &freq_mhz, 4);
memcpy(frame + 12, &g_seq_num, 4);
frame[16] = (int8_t)info->rx_ctrl.rssi;
frame[17] = (int8_t)info->rx_ctrl.noise_floor;
frame[18] = 0; frame[19] = 0;
// Write I/Q payload directly from info->buf
memcpy(frame + 20, info->buf, info->len);
// Send over UDP to aggregator
stream_sender_write(frame, 20 + info->len);
g_seq_num++;
}
```
**No on-device FFT** (contradicting ADR-012's optional feature extraction path): The Rust aggregator will do feature extraction using the SOTA `wifi-densepose-signal` pipeline. Raw I/Q is cheaper to stream at ESP32 sampling rates (~100 Hz at 56 subcarriers = ~35 KB/s per node).
**`sdkconfig.defaults`** must enable:
```
CONFIG_ESP_WIFI_CSI_ENABLED=y
CONFIG_LWIP_SO_RCVBUF=y
CONFIG_FREERTOS_HZ=1000
```
**Build toolchain**: ESP-IDF v5.2+ (pinned). Docker image: `espressif/idf:v5.2` for reproducible CI.
### Layer 2 — UDP Aggregator (`crates/wifi-densepose-hardware/src/aggregator/`)
New module within the hardware crate. Entry point: `aggregator_main()` callable as a binary target.
```rust
// crates/wifi-densepose-hardware/src/aggregator/mod.rs
pub struct Esp32Aggregator {
socket: UdpSocket,
nodes: HashMap<u8, NodeState>, // keyed by node_id from frame header
tx: mpsc::SyncSender<CsiFrame>, // outbound to bridge
}
struct NodeState {
last_seq: u32,
drop_count: u64,
last_recv: Instant,
}
impl Esp32Aggregator {
/// Bind UDP socket and start blocking receive loop.
/// Each valid frame is forwarded on `tx`.
pub fn run(&mut self) -> Result<(), AggregatorError> {
let mut buf = vec![0u8; 4096];
loop {
let (n, _addr) = self.socket.recv_from(&mut buf)?;
match Esp32CsiParser::parse_frame(&buf[..n]) {
Ok((frame, _consumed)) => {
let state = self.nodes.entry(frame.metadata.node_id)
.or_insert_with(NodeState::default);
// Track drops via sequence number gaps
if frame.metadata.seq_num != state.last_seq + 1 {
state.drop_count += (frame.metadata.seq_num
.wrapping_sub(state.last_seq + 1)) as u64;
}
state.last_seq = frame.metadata.seq_num;
state.last_recv = Instant::now();
let _ = self.tx.try_send(frame); // drop if pipeline is full
}
Err(e) => {
// Log and continue — never crash on bad UDP packet
eprintln!("aggregator: parse error: {e}");
}
}
}
}
}
```
**Testable without hardware**: The test suite generates frames using `build_test_frame()` (same helper pattern as `esp32_parser.rs` tests) and sends them over a loopback UDP socket. The aggregator receives and forwards them identically to real hardware frames.
### Layer 3 — CsiFrame → CsiData Bridge
Bridge from `wifi-densepose-hardware::CsiFrame` to the signal processing type `wifi_densepose_signal::CsiData` (or a compatible intermediate type consumed by the Rust pipeline).
```rust
// crates/wifi-densepose-hardware/src/bridge.rs
use crate::{CsiFrame};
/// Intermediate type compatible with the signal processing pipeline.
/// Maps directly from CsiFrame without cloning the I/Q storage.
pub struct CsiData {
pub timestamp_unix_ms: u64,
pub node_id: u8,
pub n_antennas: usize,
pub n_subcarriers: usize,
pub amplitude: Vec<f64>, // length: n_antennas * n_subcarriers
pub phase: Vec<f64>, // length: n_antennas * n_subcarriers
pub rssi_dbm: i8,
pub noise_floor_dbm: i8,
pub channel_freq_mhz: u32,
}
impl From<CsiFrame> for CsiData {
fn from(frame: CsiFrame) -> Self {
let n_ant = frame.metadata.n_antennas as usize;
let n_sub = frame.metadata.n_subcarriers as usize;
let (amplitude, phase) = frame.to_amplitude_phase();
CsiData {
timestamp_unix_ms: frame.metadata.timestamp_unix_ms,
node_id: frame.metadata.node_id,
n_antennas: n_ant,
n_subcarriers: n_sub,
amplitude,
phase,
rssi_dbm: frame.metadata.rssi_dbm,
noise_floor_dbm: frame.metadata.noise_floor_dbm,
channel_freq_mhz: frame.metadata.channel_freq_mhz,
}
}
}
```
The bridge test: parse a known binary frame, convert to `CsiData`, assert `amplitude[0]` = √(I₀² + Q₀²) to within f64 precision.
### Layer 4 — Python `_read_raw_data()` Real Implementation
Replace the `NotImplementedError` stub in `v1/src/hardware/csi_extractor.py` with a UDP socket reader. This allows the Python pipeline to receive real CSI from the aggregator while the Rust pipeline is being integrated.
```python
# v1/src/hardware/csi_extractor.py
# Replace _read_raw_data() stub:
import socket as _socket
class CSIExtractor:
...
def _read_raw_data(self) -> bytes:
"""Read one raw CSI frame from the UDP aggregator.
Expects binary frames in the ESP32 format (magic 0xC5110001 header).
Aggregator address configured via AGGREGATOR_HOST / AGGREGATOR_PORT
environment variables (defaults: 127.0.0.1:5005).
"""
if not hasattr(self, '_udp_socket'):
host = self.config.get('aggregator_host', '127.0.0.1')
port = int(self.config.get('aggregator_port', 5005))
sock = _socket.socket(_socket.AF_INET, _socket.SOCK_DGRAM)
sock.bind((host, port))
sock.settimeout(1.0)
self._udp_socket = sock
try:
data, _ = self._udp_socket.recvfrom(4096)
return data
except _socket.timeout:
raise CSIExtractionError(
"No CSI data received within timeout — "
"is the ESP32 aggregator running?"
)
```
This is tested with a mock UDP server in the unit tests (existing `test_csi_extractor_tdd.py` pattern) and with the real aggregator in integration.
## Development Sequence
```
Phase 1 (Firmware + Aggregator — no pipeline integration needed):
1. Write firmware/esp32-csi-node/ C project (ESP-IDF v5.2)
2. Flash to one ESP32-S3-DevKitC board
3. Verify binary frames arrive on laptop UDP socket using Wireshark
4. Write aggregator crate + loopback test
Phase 2 (Bridge + Python stub):
5. Implement CsiFrame → CsiData bridge
6. Replace Python _read_raw_data() with UDP socket
7. Run Python pipeline end-to-end against loopback aggregator (synthetic frames)
Phase 3 (Real hardware integration):
8. Run Python pipeline against live ESP32 frames
9. Capture 10-second real CSI bundle (firmware/esp32-csi-node/proof/)
10. Verify proof bundle hash (ADR-011 pattern)
11. Mark ADR-012 Accepted, mark this ADR Accepted
```
## Testing Without Hardware
All four layers are testable before a single ESP32 is purchased:
| Layer | Test Method |
|-------|-------------|
| Firmware binary format | Build a `build_test_frame()` helper in Rust, compare its output byte-for-byte against a hand-computed reference frame |
| Aggregator | Loopback UDP: test sends synthetic frames to 127.0.0.1:5005, aggregator receives and forwards on channel |
| Bridge | `assert_eq!(csi_data.amplitude[0], f64::sqrt((iq[0].i as f64).powi(2) + (iq[0].q as f64).powi(2)))` |
| Python UDP reader | Mock UDP server in pytest using `socket.socket` in a background thread |
The existing `esp32_parser.rs` test suite already validates parsing of correctly-formatted binary frames. The aggregator and bridge tests build on top of the same test frame construction.
## Consequences
### Positive
- **Layered testability**: Each layer can be validated independently before hardware acquisition.
- **No new external dependencies**: UDP sockets are in stdlib (both Rust and Python). Firmware uses only ESP-IDF and esp-dsp component.
- **Stub elimination**: Replaces the last two `NotImplementedError` stubs in the Python hardware layer with real code backed by real data.
- **Proof of reality**: Phase 3 produces a captured CSI bundle hashed to a known value, satisfying ADR-011 for hardware-sourced data.
- **Signal-crate reuse**: The SOTA Hampel/Fresnel/BVP/Doppler processing from ADR-014 applies unchanged to real ESP32 frames after the bridge converts them.
### Negative
- **Firmware requires ESP-IDF toolchain**: Not buildable without a 2+ GB ESP-IDF installation. CI must use the official Docker image or skip firmware compilation.
- **Raw I/Q bandwidth**: Streaming raw I/Q (not features) at 100 Hz × 3 antennas × 56 subcarriers = ~35 KB/s/node. At 6 nodes = ~210 KB/s. Fine for LAN; not suitable for WAN.
- **Single-antenna real-world**: Most ESP32-S3-DevKitC boards have one on-board antenna. Multi-antenna data requires external antenna + board with U.FL connector or purpose-built multi-radio setup.
### Deferred
- **Multi-node clock drift compensation**: ADR-012 specifies feature-level fusion. The aggregator in this ADR passes raw `CsiFrame` per-node. Drift compensation lives in a future `FeatureFuser` layer (not scoped here).
- **ESP-IDF firmware CI**: Firmware compilation in GitHub Actions requires the ESP-IDF Docker image. CI integration is deferred until Phase 3 hardware validation.
## Interaction with Other ADRs
| ADR | Interaction |
|-----|-------------|
| ADR-011 | Phase 3 produces a real CSI proof bundle satisfying mock elimination |
| ADR-012 | This ADR implements the development path for ADR-012's architecture |
| ADR-014 | SOTA signal processing applies unchanged after bridge layer |
| ADR-008 | Aggregator handles multi-node; distributed consensus is a later concern |

//! # WiFi-DensePose Training Infrastructure
//!
//! This crate provides the complete training pipeline for the WiFi-DensePose pose
//! estimation model. It includes configuration management, dataset loading with
//! subcarrier interpolation, loss functions, evaluation metrics, and the training
//! loop orchestrator.
//!
//! ## Architecture
//!
//! ```text
//! TrainingConfig ──► Trainer ──► Model
//! │ │
//! │ DataLoader
//! │ │
//! │ CsiDataset (MmFiDataset | SyntheticCsiDataset)
//! │ │

//! ```
//!
//! ## Quick Start
//!
//! ```rust,no_run
//! use wifi_densepose_train::config::TrainingConfig;
//! use wifi_densepose_train::dataset::{SyntheticCsiDataset, SyntheticConfig, CsiDataset};

//! let dataset = SyntheticCsiDataset::new(200, syn_cfg);
//!
//! // Load one sample
//! let sample = dataset.get(0).unwrap();
//! println!("amplitude shape: {:?}", sample.amplitude.shape());
//! ```
// Note: #![forbid(unsafe_code)] is intentionally absent because the `tch`

//! Deterministic training proof for WiFi-DensePose.
//!
//! # Proof Protocol
//!
//! 1. Create [`SyntheticCsiDataset`] with fixed `seed = PROOF_SEED`.
//! 2. Initialise the model with `tch::manual_seed(MODEL_SEED)`.
//! 3. Run exactly [`N_PROOF_STEPS`] forward + backward steps.
//! 4. Verify that the loss decreased from initial to final.
//! 5. Compute SHA-256 of all model weight tensors in deterministic order.
//! 6. Compare against the expected hash stored in `expected_proof.sha256`.
//!
//! If the hash **matches**: the training pipeline is verified real and
//! deterministic. If the hash **mismatches**: the code changed, or
//! non-determinism was introduced.
//!
//! # Trust Kill Switch
//!
//! Run `verify-training` to execute this proof. Exit code 0 = PASS,
//! 1 = FAIL (loss did not decrease or hash mismatch), 2 = SKIP (no hash
//! file to compare against).

//! the most informative subcarriers based on signal variance.
//!
//! # Example
//!
//! ```rust
//! use wifi_densepose_train::subcarrier::interpolate_subcarriers;
//! use ndarray::Array4;
//!
//! // Resample from 114 → 56 subcarriers
//! let arr = Array4::<f32>::zeros((100, 3, 3, 114));
//! let resampled = interpolate_subcarriers(&arr, 56);
//! assert_eq!(resampled.shape(), &[100, 3, 3, 56]);
//! ```

//! Training loop for WiFi-DensePose.
//!
//! # Features
//!
//! - Mini-batch training with [`DataLoader`]-style iteration
//! - Validation every N epochs with PCK\@0.2 and OKS metrics
//! - Best-checkpoint saving (by validation PCK)
//! - CSV logging (`epoch, train_loss, val_pck, val_oks, lr`)
//! - Gradient clipping
//! - LR scheduling (step decay at configured milestones)
//! - Early stopping
//!
//! # No mock data
//!
//! The trainer never generates random or synthetic data. It operates
//! exclusively on the [`CsiDataset`] passed at call site. The
//! [`SyntheticCsiDataset`] is only used for the deterministic proof protocol.

//! Tests that depend on functions not yet implemented (`run_proof`,
//! `generate_expected_hash`) are marked `#[ignore]` so they compile and
