//! Mnemos's `ProvenanceSource` marker.
//!
//! Migrated to the [`converge_pack::ProvenanceSource`] trait. Public
//! surface is unchanged at call sites:
//! `MNEMOS_PROVENANCE.proposed_fact(...)` reads the same.
//!
//! The `converge-core` engine emits the uniform `suggestor.execute`
//! tracing span automatically around every `Suggestor::execute`
//! call. Suggestors override `Suggestor::provenance()` to return
//! `MNEMOS_PROVENANCE.as_str()` so the engine's span carries the
//! right origin.
