Enum CheckpointConsistencyAnchor 

pub enum CheckpointConsistencyAnchor<'a> {
    Genesis,
    VerifiedChainRoot(Hash),
    ChainPrefix(&'a [Hash]),
}

What ties the prefix below a consistency proof’s earlier endpoint to a history the verifier accepts.

A pair-level proof constrains nothing before its earlier endpoint, so for a pair starting after checkpoint 1 a signing-key holder can commit an earlier tree whose leading leaves are fabricated, append the later real leaf, re-sign both bodies, and produce paths that verify.

Variants

Genesis

The earlier endpoint is checkpoint 1, so its chain tree is exactly its own leaf and no prefix exists to fabricate.

VerifiedChainRoot(Hash)

A chain root the verifier already accepted for the earlier endpoint.

ChainPrefix(&'a [Hash])

Every chain leaf from checkpoint 1 through the earlier endpoint.
