# redevplugin-contracts
`redevplugin-contracts` embeds the versioned machine contracts published by the
ReDevPlugin platform. It exposes validated contract IDs, immutable canonical
bytes, hashes, registry metadata, and the platform package set. It also exposes
typed, domain-separated canonical release-signing DTOs, preimage builders,
strict decoders, detached signing-ledger evidence DTOs, and a verifier trait for
host-selected cryptography.
The crate is opt-in. The runtime and ordinary Host dependency graphs use only
the generated contract-set digest and do not link the raw contract bodies.
