Struct Receipt 

pub struct Receipt {
    pub receipt_id: String,
    pub hash: String,
    pub prev_receipt_hash: Option<String>,
}

A content-addressed ledger entry: hash is the digest of an artifact’s exact bytes, and prev_receipt_hash closes the Merkle chain (None only for genesis). See the runnable witness in examples/receipt_chain_explained.rs, which demonstrates content-addressing, tamper detection, the circular-hash trap, and chain linkage — and panics if any of them regress. For receipt verification driving the conformance gate, see examples/admission_pipeline.rs.

Fields

receipt_id: String

hash: String

prev_receipt_hash: Option<String>

Hash of the immediately preceding receipt in the instance ledger. None for genesis (first) receipts only. All subsequent receipts must set this to close the Merkle chain and make verify_instance_ledger meaningful for non-LSP_1 instances.
