# OATS Architecture
## Objects • Actions • Traits • Systems

**Universal architecture pattern for infinite scale across any domain.**

OATS is domain-agnostic operational intelligence. Whether you're building enterprise software, game engines, distributed systems, or operating systems - this pattern eliminates architectural complexity that kills scale at growth inflection points.

## 🏗️ Architecture Overview

OATS (Objects • Actions • Traits • Systems) is a universal architecture pattern for infinite scale across any domain.

[dependencies]
oats-framework = "0.1.0"
```

Or use the latest from this repository:

```toml
[dependencies]
oats-framework = { git = "https://github.com/TheNexusGroup/oats-framework" }
```

## 🏗️ Core Abstractions

### 🏢 **Objects** - Identity Containers
Pure composition. Zero behavior pollution. Maximum modularity.

```rust
use oats_framework::{Object, Trait, TraitData};

// Create an object
let mut player = Object::new("player_1", "character");

// Add traits to the object
let health_trait = Trait::new("health", TraitData::Number(100.0));
let position_trait = Trait::new("position", TraitData::Object(HashMap::new()));
player.add_trait(health_trait);
player.add_trait(position_trait);

// Access traits
if let Some(health) = player.get_trait("health") {
    println!("Health: {:?}", health.data());
}
```

### 💎 **Traits** - Domain State
Immutable data structures. Single source of truth. Auditable state management.

```rust
use oats_framework::{Trait, TraitData};

// Create traits with different data types
let string_trait = Trait::new("name", TraitData::String("Hero".to_string()));
let number_trait = Trait::new("level", TraitData::Number(5.0));
let bool_trait = Trait::new("active", TraitData::Boolean(true));

// Complex structured data
let mut position_data = HashMap::new();
position_data.insert("x".to_string(), serde_json::json!(10.0));
position_data.insert("y".to_string(), serde_json::json!(20.0));
let position_trait = Trait::new("position", TraitData::Object(position_data));
```

### ⚡ **Actions** - Pure Business Logic
Stateless operations. Horizontally scalable. Domain-independent processing.

```rust
use oats_framework::{Action, ActionContext, ActionResult};

// Create a custom action
struct HealAction;

#[async_trait::async_trait]
impl Action for HealAction {
    fn name(&self) -> &str { "heal" }
    fn description(&self) -> &str { "Restores health to target" }
    
    async fn execute(&self, context: ActionContext) -> Result<ActionResult, oats_framework::OatsError> {
        let target = context.get_object("target").unwrap();
        let current_health = target.get_trait("health")
            .and_then(|t| t.data().as_number())
            .unwrap_or(0.0);
        
        let new_health = (current_health + 25.0).min(100.0);
        let health_trait = Trait::new("health", TraitData::Number(new_health));
        
        let mut result = ActionResult::success();
        result.add_trait_update(health_trait);
        result.add_message(format!("Healed {} to {:.1} health", target.name(), new_health));
        Ok(result)
    }
}

// Execute the action
let mut context = ActionContext::new();
context.add_object("target", player.clone());
let result = heal_action.execute(context).await?;
```

### 🎯 **Systems** - Operational Orchestration
Resource allocation. Priority management. Cross-domain coordination.

```rust
use oats_framework::{System, SystemManager, Priority};

// Create a system
struct HealthSystem {
    stats: oats_framework::systems::SystemStats,
}

#[async_trait::async_trait]
impl System for HealthSystem {
    fn name(&self) -> &str { "health_system" }
    fn description(&self) -> &str { "Manages health-related operations" }
    
    async fn process(&mut self, objects: Vec<Object>, priority: Priority) -> Result<Vec<ActionResult>, oats_framework::OatsError> {
        // Your custom processing logic here
        Ok(vec![])
    }
}

// Create a system manager
let mut manager = SystemManager::new();
manager.add_system(Box::new(HealthSystem::new()));

// Register objects
manager.register_object(player).await;

// Process all objects through all systems
let results = manager.process_all(Priority::Normal).await?;
```

## 🔧 Advanced Usage

### Custom Actions
```rust
use oats_framework::{Action, ActionContext, ActionResult};

struct CustomAction {
    parameter: String,
}

#[async_trait::async_trait]
impl Action for CustomAction {
    fn name(&self) -> &str { "custom_action" }
    fn description(&self) -> &str { "A custom action" }
    
    async fn execute(&self, context: ActionContext) -> Result<ActionResult, oats_framework::OatsError> {
        // Your custom logic here
        let mut result = ActionResult::success();
        result.add_message("Custom action executed");
        Ok(result)
    }
}
```

### Custom Systems
```rust
use oats_framework::{System, Priority};

struct CustomSystem {
    name: String,
    stats: oats_framework::systems::SystemStats,
}

#[async_trait::async_trait]
impl System for CustomSystem {
    fn name(&self) -> &str { &self.name }
    fn description(&self) -> &str { "A custom system" }
    
    async fn process(&mut self, objects: Vec<Object>, priority: Priority) -> Result<Vec<ActionResult>, oats_framework::OatsError> {
        // Your custom processing logic here
        Ok(vec![])
    }
}
```

### Error Handling
```rust
use oats_framework::{Result, OatsError};

fn handle_oats_operation() -> Result<()> {
    // OATS operations return Result<T, OatsError>
    let object = Object::new("test", "type");
    
    // Handle specific error types
    match some_operation() {
        Ok(result) => Ok(result),
        Err(OatsError::ObjectNotFound { id }) => {
            println!("Object not found: {}", id);
            Err(OatsError::object_not_found("new_id"))
        }
        Err(e) => Err(e),
    }
}
```

## 🏗️ Architecture Benefits

**Resource Optimization**: Systems prioritize compute allocation based on domain-specific business value. Critical operations get premium resources. Background processes fill remaining capacity.

**Infinite Horizontal Scale**: Stateless actions distribute across any infrastructure topology. Add processing power without architectural changes.

**Technical Debt Prevention**: Pure separation eliminates circular dependencies across all domains. New capabilities deploy without touching existing operational logic.

**Operational Intelligence**: Architecture maps directly to measurable business outcomes regardless of industry vertical.

## 🌍 Universal Scaling Properties

This pattern runs the foundational infrastructure behind every platform that achieved global scale without architectural rewrites. From AWS to Unity, from Kubernetes to financial trading systems - OATS abstractions create operational superiority that compounds across any domain.

**OATS transforms complexity into competitive advantage.**
