Function verify_identity 

pub fn verify_identity(
    identity: &AdapterIdentity,
    reported_abi_version: u32,
    reported_layout_hash: u32,
) -> Result<(), AdapterIdentityError>

Verifies a captured identity against this exact Rust crate build.

reported_abi_version and reported_layout_hash are separate adapter exports. Comparing them prevents a stale or partially implemented adapter from satisfying the contract with a single fabricated struct. The private C layout cannot be recomputed in Rust, so its non-zero identity is authorized by the independently matched repository adapter-source digest.
