# alkstore-mem

The mem engine of the [alkstore](https://git.alk.dev/alkdev/alkstore/blob/main/README.md)
family: the full core contract v1 implemented on guarded in-process
state — every mechanism, every guarantee row — with zero
configuration.

```rust
let store = alkstore_mem::MemStore::new();
```

**Engine posture — honest-ephemeral.** No durability, single-process,
never fleet-valid: there is no cross-process story at all, loss on
process exit is the documented posture, and the dependency on this
crate *is* the ephemerality declaration. Each `MemStore::new()` yields
a fully isolated instance sharing nothing; teardown is drop. The
dependency on tokio is restricted to the wasm-supported subset (sync +
time) — this crate compiles clean on `wasm32-unknown-unknown`, the
family member that runs in the sandbox.

See the [family README](https://git.alk.dev/alkdev/alkstore/blob/main/README.md)
for the interface and the deployment matrix, and the
[mem engine spec](https://git.alk.dev/alkdev/alkstore/blob/main/docs/architecture/engine-mem.md)
for the architecture.
