Enum FailureMode 

#[non_exhaustive]
pub enum FailureMode {
    Deny,
    FallThrough,
}

What an approval policy or capability middleware does when the policy cannot be evaluated (transport failure, engine error, invalid response).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Deny

Fail closed: deny the call (or clear the tools).

FallThrough

Fail open: fall through to the tool’s own needs_approval (or keep the tools unchanged).
