## Overview

The Lean Agentic Learning System represents a new paradigm in machine learning that integrates:

1. **Lean Theorem Proving** - Mathematical rigor and formal verification
2. **Agentic AI** - Autonomous decision-making with goal-oriented behavior
3. **Stream Learning** - Real-time online adaptation from continuous data
4. **Knowledge Evolution** - Dynamic knowledge graphs that grow with experience

### Key Features

- ✅ **Formal Verification** - Every action can be proven safe and correct
- 🎯 **Autonomous Agents** - Self-directed learning and decision-making
- 📊 **Real-Time Adaptation** - Learn from streaming data without batch processing
- 🧠 **Knowledge Graphs** - Build and evolve structured knowledge dynamically
- ⚡ **Low Latency** - Process and learn from streams in real-time
- 🔒 **Type Safe** - Full Rust implementation with TypeScript client
- 🌐 **Multi-Language** - Rust core with TypeScript, Python bindings

## Core Innovations

### 1. Lean Formal Reasoning

Inspired by the Lean theorem prover, our system provides:

```rust
use midstream::{FormalReasoner, Theorem, Proof};

let mut reasoner = FormalReasoner::new();

// Add axioms
reasoner.add_axiom(Theorem {
    statement: "Actions must not cause harm".to_string(),
    confidence: 1.0,
    tags: vec!["safety".to_string()],
    ..Default::default()
});

// Verify actions before execution
let proof = reasoner.verify_action(&action, &context).await?;

if proof.is_valid() {
    // Safe to execute
    execute_action(&action).await?;
}
```

**Benefits:**
- Provably safe agent behavior
- Mathematical guarantees on action correctness
- Explainable decision-making
- Verified knowledge accumulation

### 2. Agentic Loop (Plan-Act-Observe-Learn)

Our autonomous agent loop enables self-directed learning:

```
┌─────────────────────────────────────┐
│        Agentic Learning Loop        │
├─────────────────────────────────────┤
│                                     │
│  1. PLAN                            │
│     └─ Analyze context              │
│        └─ Generate action candidates│
│           └─ Rank by expected reward│
│                                     │
│  2. ACT                             │
│     └─ Verify action (formal proof) │
│        └─ Execute highest-value     │
│                                     │
│  3. OBSERVE                         │
│     └─ Collect outcomes             │
│        └─ Measure actual reward     │
│                                     │
│  4. LEARN                           │
│     └─ Update policies              │
│        └─ Refine knowledge graph    │
│           └─ Adapt model weights    │
│                                     │
└─────────────────────────────────────┘
```

**Example:**

```rust
use midstream::{AgenticLoop, LeanAgenticConfig, Context};

let mut agent = AgenticLoop::new(config);
let context = Context::new("session_001".to_string());

// PLAN
let plan = agent.plan(&context, "Get weather for Tokyo").await?;

// ACT
let action = agent.select_action(&plan).await?;
let observation = agent.execute(&action).await?;

// OBSERVE & LEARN
let reward = agent.compute_reward(&observation).await?;
agent.learn(LearningSignal { action, observation, reward }).await?;
```

### 3. Stream Learning

Unlike traditional batch learning, our system learns continuously:

```rust
use midstream::{StreamLearner, AdaptationStrategy};

let mut learner = StreamLearner::new(0.01); // Learning rate

// Process stream in real-time
for chunk in stream {
    let entities = kg.extract_entities(&chunk).await?;
    kg.update(entities).await?;

    let action = agent.select_action(&context).await?;
    let reward = execute_and_measure(&action).await?;

    // Online learning - updates happen immediately
    learner.update(&action, reward, &chunk).await?;
}
```

**Adaptation Strategies:**

1. **Immediate** - Update after every experience (fastest adaptation)
2. **Batched** - Update after N experiences (stable learning)
3. **Experience Replay** - Randomly replay past experiences (better generalization)

### 4. Dynamic Knowledge Graph

Knowledge evolves as the system learns:

```rust
use midstream::{KnowledgeGraph, Entity, Relation, EntityType};

let mut kg = KnowledgeGraph::new();

// Extract entities from streaming text
let entities = kg.extract_entities("Alice works at Google").await?;

// Entities found: ["Alice" (Person), "Google" (Organization)]

// Update graph
kg.update(entities).await?;

// Add relations
kg.add_relation(Relation {
    subject: "alice_id".to_string(),
    predicate: "works_at".to_string(),
    object: "google_id".to_string(),
    confidence: 0.9,
    ..Default::default()
});

// Query related entities
let related = kg.find_related("alice_id", max_depth: 2);

// Time-based facts
kg.add_temporal_fact(TemporalFact {
    fact: "Weather is sunny".to_string(),
    valid_from: now,
    valid_until: Some(now + 3600),
    confidence: 0.9,
});
```

let config = LeanAgenticConfig {
    enable_multi_agent: true,
    ..Default::default()
};

// Multiple agents can share knowledge graph
// Collaborative learning and decision-making
```

let mut reasoner = FormalReasoner::new();

reasoner.add_rule(InferenceRule {
    name: "custom_rule".to_string(),
    premises: vec!["A".to_string(), "B".to_string()],
    conclusion: "C".to_string(),
});
```

### Knowledge Graph Queries

```rust
// Query by type
let people = kg.query_entities(EntityType::Person);

// Find related entities
let related = kg.find_related("entity_id", max_depth: 3);

// Temporal queries
let facts_now = kg.get_facts_at_time(timestamp);

// Semantic similarity
let similarity = kg.compute_similarity("entity1", "entity2");
