// name the sessions that closed — without them it would accept every unfinalized
// capture handle and report clean, which is the vacuous mode the type system now
// refuses in code. The standalone CLI is the one caller that builds options from
// strings rather than types, so it must refuse the same invocation at runtime
// instead of silently degrading to that mode.
