Struct ChainValidationConfig 

pub struct ChainValidationConfig {
    pub max_depth: u32,
}

Configuration for delegation chain validation.

SR-8: Maximum delegation depth

Without a depth limit, an attacker can construct arbitrarily deep delegation chains, creating denial-of-service via quadratic chain validation cost and enabling privilege confusion through deeply nested delegation.

Fields

max_depth: u32

Maximum number of delegation hops allowed (default: 5, hard max: 10).

A depth of 1 means the root (human) issuer → agent (no re-delegation). A depth of 2 means human → orchestrator → tool-agent. Values above 10 are clamped to 10.

Implementations

impl ChainValidationConfig

pub const HARD_MAX_DEPTH: u32 = 10

The hard maximum depth — cannot be overridden.

pub fn with_max_depth(max_depth: u32) -> Self

Create a config with a specific depth limit (clamped to HARD_MAX_DEPTH).
