Local artifact storage for [Kache](https://github.com/kunobi-ninja/kache), a compiler cache for Rust, C/C++ and CUDA: content-addressed blobs, entry metadata, a SQLite index, file fingerprints, locks, reclamation and linking into build directories.

## What it provides

- `ArtifactStore<P>`: the store itself. An `ArtifactPolicy` you supply decides which outputs may share an inode, which may be empty, which emit kinds they satisfy, and whether their hashes stay valid after publication.
- `link`: restoring blobs into a build directory by reflink, hardlink or copy.
- `eviction`: choosing which entries garbage collection removes.
- `file_hash`: fingerprints of input files, kept across builds.
- A durable upload spool that records what should be published. The caller does the transfer.

Compiler parsing, daemon communication and remote transport live outside this crate. Disk formats and the cache-key version come from [`kache-format`](https://crates.io/crates/kache-format).
