Function detector_digest 

pub fn detector_digest() -> &'static str

Effective digest identifying the EXACT embedded detector set and the directory-scoped corpus.toml schema contract compiled into this binary (<detector-count>-<fnv1a_hex>). Binding the manifest ensures caches, benchmarks, and autoroute evidence invalidate when parsing compatibility semantics change even if detector TOML bytes do not. Stamped by build.rs via cargo:rustc-env=KEYHOG_DETECTOR_DIGEST, this is the authoritative answer to “which effective corpus was compiled in” when cargo’s rerun-if-changed cannot be trusted across in-place TOML edits.
