//! Deterministic, sharded census of the canonical Workshop surface.
//!
//! The census is derived from this crate's catalog, settings table, and WIR
//! capabilities. It is tooling that runs contract/regression probes and
//! produces structured results, not a source-language inventory or a
//! live-client oracle.
