3//! The mutable store itself lives on [`crate::EventLog`] (same SQLite file);
4//! this module holds the small pure pieces: how a command is hashed into a
5//! stable key for the per-repo always-allow / always-deny memory.

12/// command in this repo" means exactly that — a different command, even by a
13/// space, is a different key.
