# Layer L5: Semantic

## Overview
Meaning-aware filtering, manifold routing, and compression governance.

## Status
🟡 **Partial** - Projection receipts exist, partial implementation

## Key Components

### CrossDimensionalFilter
- 12 semantic primes
- Multi-dimensional filtering
- Semantic content analysis

### Manifold Networking
- Semantic routing system
- Meaning-based connections
- Information flow optimization

### BracketedCalculus
- Context-aware computation
- Nested operation handling
- Scope management

### CompressionControl
- Compression governance
- Rate-distortion optimization
- Information preservation

## Formal Proofs
- [[Semantic Filtering Correctness]]
- [[Manifold Routing Completeness]]

## Documentation
- [[Semantic Primes Reference]]
- [[Routing Algorithms]]
- [[Compression Governance]]
