omgbase-store

The omgbase store, Rust implementation: the embedded SQLite database that owns block identity, history and the current state of a repository of authored files. It opens the same databases as the TypeScript reference (@omgbase/core) and passes the same fixtures. The contract is spec/store/README.md in the omgbase repository; schema.sql (embedded here verbatim) is the DDL, and spec/store/cases/*.json are the executable fixtures the conformance runner (tests/spec.rs) executes.

use omgbase_reconcile::Config;
use omgbase_store::{BatchItem, Store};

let mut store = Store::open_in_memory()?;
let repo = store.create_repo("notes")?;
let items = [BatchItem::observed("a.md", "# Title\n\nFirst.\n")];
let outcomes = store.observe_batch(&repo, &items, "2026-09-26T10:00:00.000Z", &Config::default())?;
assert!(outcomes[0].as_observed().unwrap().converged);
# Ok::<(), omgbase_store::Error>(())

The crate version tracks the spec: the major is the schema user_version (13), the minor counts semantic changes without DDL.
