| Task adds two new roles to UCAN: invoker and executor. The existing UCAN delegator and delegate principals MUST persist to the invocation. | ||

The existing UCAN delegator and delegate principals MUST persist to the invocation.
I'd love this to be unpacked a bit, it's too terse for me. Are you saying that the same identifiers used for principals at delegation time MUST be dereferenceable (by the executor) at invocation time? I feel like phrasing that in terms of local context or dereferencing is preferable to making it sound more existential (and untestable) as some kind of... survival in a hostile [distributed] environment 😅

| The OPTIONAL `aud` field specified the intended recipient of Invocation, otherwise the Audience MUST be assumed to the [Subject]. This is useful for message routing, command brokers, proxy execution, gateways, replicated state machines, and so on. |

But aud is still REQUIRED in the high-level UCAN spec?
