Crate harmonia_store_core 

Core Nix store semantics.

This crate provides the fundamental types and pure computation logic for working with the Nix store. It is intentionally IO-free - all operations are pure functions that operate on values, enabling easy testing and composition.

Architecture: This is the Core Layer in Harmonia’s store architecture. See docs/architecture/harmonia-store-structure.md for details.

Key Modules

• hash - Content addressing, hash types, hash computation
• store_path - Store path types, parsing, validation
• derivation - Derivation (.drv) file format and semantics
• signature - Cryptographic signatures for store paths
• realisation - Store path realisation tracking

Design Principles

1. No IO: No filesystem, no network, minimal async
2. Pure functions: Deterministic, testable, referentially transparent
3. Explicit errors: All fallible operations return Result
4. Memory-bounded: Stream-friendly, no unbounded buffers
