      summary: List the mailboxes this org can bind as sequence email senders
      description: >-
        Every email mailbox of the organization with its bindability verdict AND
        its health NUMBERS. `eligible` mailboxes are accepted by
        setSequenceSenders on the email channel; ineligible ones carry the
        reason (`not_active` — still provisioning or paused; `domain_not_live` —
        its domain lapsed, so sending would fail authentication). `health`
        carries warm-up status, inbox rate, spam rate, an overall score,
        warming-since, and the share of recent real sends that hard-bounced with
        its sample size. There is deliberately no pass/fail: a null is "not
        known yet" (common for a new mailbox), never "bad", and nothing here
        blocks a send or a binding.
