# Vapora Tracking System

A unified tracking and change logging system for Vapora projects. Provides a "project cuaderno de bitácora" (logbook) for aggregating changes, TODOs, and tracking across multiple sources with real-time synchronization.

## 🎯 Features

### Core Capabilities
- **Unified Tracking**: Aggregates changes and TODOs from multiple sources
  - Claude Code tracking files (`~/.claude/todos/`)
  - `.coder/` directory tracking (`changes.md`, `todo.md`)
  - Workflow YAML definitions
- **Real-time Sync**: File watchers detect changes and automatically sync
- **REST API**: Axum-based HTTP API for queries and management
- **SQLite Storage**: Persistent storage with efficient indexing
- **Multi-format Export**: JSON, CSV, Markdown, Kanban board formats

### Integration Points
- **Slash Commands**: `/log-change`, `/add-todo`, `/track-status`
- **Interactive Skill**: Guided workflows for comprehensive logging
- **Nushell Scripts**: `sync-tracking`, `export-tracking`, `start-tracking-service`
- **Claude Code Hooks**: Automatic event synchronization

## 📦 Architecture

### Modular Design
```

├── types.rs        # Core types with Debug/Display
├── error.rs        # Canonical error handling
├── parsers.rs      # Markdown, JSON, YAML parsing
├── storage.rs      # SQLite async persistence

```

### Data Flow
```
File Changes (.coder/, ~/.claude/)
         ↓
  File Watchers (notify)
         ↓
  Parsers (markdown, JSON)
         ↓
  SQLite Storage
         ↓
  REST API ← Queries
```

## 🚀 Quick Start

### Installation

Add to `Cargo.toml`:
```toml
[dependencies]
vapora-tracking = { path = "crates/vapora-tracking" }
```

### Basic Usage

```rust
use vapora_tracking::{TrackingDb, MarkdownParser, TrackingEntry};
use std::sync::Arc;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Initialize database
    let db = Arc::new(TrackingDb::new("sqlite://tracking.db").await?);

    // Parse markdown changes
    let content = std::fs::read_to_string(".coder/changes.md")?;
    let entries = MarkdownParser::parse_changes(&content, "/project")?;

    // Store entries
    for entry in entries {
        db.insert_entry(&entry).await?;
    }

    // Query summary
    let summary = db.get_summary().await?;
    println!("Total entries: {}", summary.total_entries);

    Ok(())
}
```

### Using Slash Commands

```bash
# Log a change
/log-change "Implemented WebSocket sync" --impact backend --files 12

# Add a TODO
/add-todo "Refactor database" --priority H --estimate XL --due 2025-11-20

# Show status
/track-status --project vapora --status pending
```

### Using Nushell Scripts

```bash
# Start tracking service
./scripts/start-tracking-service.nu --port 3000 --verbose

# Sync all projects
./scripts/sync-tracking.nu --projects-dir /Users/Akasha --verbose

# Export to different formats
./scripts/export-tracking.nu json --output report
./scripts/export-tracking.nu kanban --project vapora
```

## 📊 Data Structures

### TrackingEntry
```rust
pub struct TrackingEntry {
    pub id: Uuid,
    pub project_path: PathBuf,
    pub source: TrackingSource,
    pub entry_type: EntryType,
    pub timestamp: DateTime<Utc>,
    pub summary: String,
    pub details_link: Option<PathBuf>,
    pub metadata: HashMap<String, String>,
}
```

### Entry Types

**Changes**:
- Impact: Backend, Frontend, Security, Performance, Docs, Infrastructure, Testing
- Breaking change indicator
- Files affected count

**TODOs**:
- Priority: High, Medium, Low
- Estimate: Small, Medium, Large, Extra Large
- Status: Pending, In Progress, Completed, Blocked
- Tags for categorization

## 🔗 Integration with Vapora

### Recommended Setup

1. **Start tracking service**:
   ```bash
   # From repository root
   cargo run -p vapora-backend -- --enable-tracking
   ```

2. **Configure Claude Code**:
   - Hook: `~/.claude/hooks/tracking-sync.sh`
   - Commands: `.claude/commands/log-change.md`, etc.
   - Skill: `.claude/skills/tracking.md`

3. **Watch projects**:
   ```bash
   ./scripts/sync-tracking.nu --watch-dirs /Users/Akasha
   ```

### REST API Endpoints

```
GET  /api/v1/tracking/entries              # List all entries
GET  /api/v1/tracking/summary              # Get summary statistics
GET  /api/v1/tracking/projects/:project    # Get project entries
POST /api/v1/tracking/sync                 # Sync from file
```
