qssm-utils
Internal utility crate for the QSSM truth-engine workspace.
This crate is frozen for institutional use, but it is still an internal
building block. External consumers should use the facade crates instead of
depending on qssm-utils directly.
What Lives Here
- Versioned BLAKE3 domain tags
blake3_hash()andhash_domain()PositionAwareTreeandmerkle_parent()- Entropy screening helpers:
verify_density(),validate_entropy_distribution(), andvalidate_entropy_full()
Contributor Rules
- Do not change domain tags, Merkle proof order, padding behavior, or entropy gate semantics without a new audit cycle.
- Keep public error enums
#[non_exhaustive]. - Do not add secret-handling APIs here casually. This crate currently has no zeroization or constant-time requirements because it holds no secrets.
- Treat
FREEZE.mdandSECURITY_CHECKLIST.mdas the authoritative review record for frozen behavior.
