1//! Nix-Env-Manager: Nix Flakes and Attic Integration for AIVCS
2//!
3//! This crate provides the environment versioning layer for AIVCS.
4//! It interfaces with Nix Flakes for deterministic builds and
5//! Attic for binary caching.
6//!
7//! ## Layer 2 - Environment/Tooling
8//!
9//! Focus: Correct hash generation and dependency resolution.
10//!
11//! ## Features
12//!
13//! - Generate content-addressable hashes from Nix Flakes
14//! - Interact with Attic binary cache for environment storage
15//! - Hash Rust source code for logic versioning
