Struct SubScopeProof 

pub struct SubScopeProof {
    pub subset_intents: Vec<IntentHash>,
    pub proofs: Vec<MerkleProof>,
}

Cryptographic evidence that a delegated scope is a strict subset of the delegator’s authorized intent set.

Each entry in subset_intents has a corresponding Merkle proof against the parent scope root. After verification, the subset is formed into its own Merkle tree whose root becomes the child scope root.

An empty SubScopeProof is a full-scope pass-through: the child receives the same scope root as the parent. This is explicit in the API — callers must consciously choose between SubScopeProof::full_passthrough and SubScopeProof::build.

Fields

subset_intents: Vec<IntentHash>

proofs: Vec<MerkleProof>

Implementations

impl SubScopeProof

pub fn full_passthrough() -> Self

Full-scope pass-through: the delegated scope equals the parent scope.

pub fn build( parent_tree: &IntentTree, intents: &[IntentHash], ) -> Result<Self, A1Error>

Build a sub-scope proof by proving each intent against parent_tree. Returns A1Error::IntentNotFound if any intent is absent from the tree.

pub fn verify_and_derive_root( &self, parent_root: &IntentHash, ) -> Result<IntentHash, A1Error>

Verify every subset intent against parent_root, then return the Merkle root of the subset as the new delegated scope root.

Returns A1Error::InvalidSubScopeProof if any proof fails.

pub fn commitment(&self) -> [u8; 32]

A deterministic commitment to the full proof structure.

Included in every certificate signature so no one can substitute a different proof on an existing certificate.
