+> [!IMPORTANT]
+> **Archived 2026-10-15.** Superseded by [Assay](https://github.com/shmindmaster/assay), a reference architecture for deterministic agent control.
+> Why: the same agent writes both the change and its evidence manifest, so the gate proves coverage and hash pinning, not that a claim is true. Assay moves the decision into deterministic code instead.
+> The last release, 0.6.4, stays on npm. The rest of this README is unchanged.
