//! # ARMS - Attention Reasoning Memory Store
//!
//! > "The hippocampus of artificial minds"
//!
//! ARMS is a spatial memory fabric for AI models. It stores computed attention
//! states at their native dimensional coordinates, enabling instant retrieval
//! by proximity rather than traditional indexing.
//!
//! ## Philosophy
//!
//! - **Position IS relationship** - No foreign keys, proximity defines connection
//! - **Configurable, not hardcoded** - Dimensionality, proximity functions, all flexible
//! - **Generators over assets** - Algorithms, not rigid structures
//! - **Pure core, swappable adapters** - Hexagonal architecture
//!
//! ## Architecture
//!

//! │                                                              │

//! ```
//!
//! ## Quick Start
//!
//! ```rust,ignore
//! use arms::{Arms, ArmsConfig, Point};
//!
//! // Create ARMS with default config (768 dimensions)
//! let mut arms = Arms::new(ArmsConfig::default());
//!
//! // Place a point in the space
//! let point = Point::new(vec![0.1; 768]);
//! let id = arms.place(point, b"my data".to_vec());
//!
//! // Find nearby points
//! let query = Point::new(vec![0.1; 768]);
//! let neighbors = arms.near(&query, 5);
//! ```

/// The five primitives of ARMS:
///
/// 1. **Point**: `Vec<f32>` - Any dimensionality
/// 2. **Proximity**: `fn(a, b) -> f32` - How related?
/// 3. **Merge**: `fn(points) -> point` - Compose together
/// 4. **Place**: `fn(point, data) -> id` - Exist in space
/// 5. **Near**: `fn(point, k) -> ids` - What's related?
///
/// Everything else is configuration or adapters.
