Struct CallSite 

pub struct CallSite {
    pub caller: Principal,
    pub callee_method: MethodPath,
}

Identifies a single edge in the call graph at the moment a policy runs.

Constructed by the framework at the dispatch point (route_to_child in plexus-core, wired in by AUTHLANG-3) and passed to ForwardPolicy::forward. Policies inspect it to make routing-aware decisions (e.g., “PassThrough only when callee is in audit.*”); the three built-in policies ignore it.

Per AUTHZ-0 vocabulary: caller and callee, NOT parent/child.

Fields

caller: Principal

The framework-stamped immediate-caller principal. Sealed value; the framework auto-stamps it at dispatch per AUTHZ-0 principle 6.

callee_method: MethodPath

The fully qualified method path on the callee being invoked (e.g., solar.earth.luna.info).

Implementations

impl CallSite

pub fn new(caller: Principal, callee_method: MethodPath) -> CallSite

Construct a CallSite from its sealed components.

CallSite is a thin coupling of a sealed Principal with a validated MethodPath. It is not itself sealed beyond the seals on its fields: a downstream crate that already holds a Principal (it cannot — the constructors are pub(crate)) and a valid MethodPath could synthesize one. The construction path that matters in practice is the framework’s route_to_child (AUTHLANG-3), which holds the only access to a freshly stamped Principal.
