# memstead-git-branch
Mem-repo engine backend for
[Memstead](https://github.com/memstead/memstead) — the schema-agnostic
graph engine that gives AI agents a durable, typed memory stored as plain
markdown in git.
> **Stability:** this crate is an internal library of the Memstead engine,
> consumed by the `memstead` / `memstead-mcp` binaries. Its Rust API is
> pre-1.0 and experimental — it changes without deprecation cycles. For a
> stable contract, consume the binaries or the MCP surface instead.
This crate implements the git-backed storage backend: each mem lives as
its own root in a multi-root `mem-repo` git repository, mutations are
applied as git tree edits (no working-tree writes for mem content), and
every commit carries provenance. It supplies the full multi-mem surface —
history, diffing, optimistic locking via content hashes, packaging
(`.mem` export/import), and the tantivy-backed search index.
This is the backend the shipped `memstead` and `memstead-mcp` binaries
compile in by default (their `mem-repo` feature).
## Use
Most users want the [`memstead-cli`](../memstead-cli/)
binary or the [`memstead-mcp`](../memstead-mcp/)
server rather than this library. Depend on `memstead-git-branch` to embed
the git-backed engine in your own process.
