Enum Caller 

pub enum Caller<'a> {
    Root,
    Workflow,
    Subagent {
        allow: Option<&'a [String]>,
    },
    Principal {
        role: Role,
        grants: &'a [String],
    },
}

The caller asking for definitions / permission.

Variants

Root

Workflow

Subagent

A subagent, optionally restricted to an explicit allow-list (subagent.run.tools).

Fields

allow: Option<&'a [String]>

Principal

An A2A principal with a role and its explicit grants (patterns).

Used to compute what a principal may SEE (defs_for). Inbound A2A calls are authorized by the role matrix in a2a::principals rather than through this arm, because a principal’s reach is decided at the protocol boundary before any tool is chosen; narrowing per principal WITHIN one daemon is security.policies, whose match: {principal} judges the call itself.

Fields

role: Role

grants: &'a [String]
