      summary: List the phone agents this org can bind as sequence voice senders
      description: >-
        Every AI phone agent of the organization with its bindability verdict.
        `eligible` agents are accepted by setSequenceSenders on the voice
        channel; ineligible ones carry the reason — `no_caller_number` means
        attach a verified number to the agent first (setPhoneAgentCallerNumber).
        Each entry also carries the mission the agent already has:
        `first_message` (spoken verbatim before the step's call brief can
        influence anything) and `persona`. Eligibility says an agent CAN dial;
        those two say whether it should dial for THIS sequence.
