//! Prism's `ProvenanceSource` marker.
//!
//! Migrated to the [`converge_pack::ProvenanceSource`] trait. Public
//! surface is unchanged at call sites:
//! `PRISM_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
//! `PRISM_PROVENANCE.as_str()` so the engine's span carries the
//! right origin.
//!
//! `prism_execution_identity()` continues to expose the static
//! [`converge_pack::ExecutionIdentity`] for any prism payload that
//! wants to carry one (today thin: prism has no native backend).
