 * Every nonterminal `agent/local`/`agent/self` handle is covered: `running`
 * and `parked` handles carry a confirmed address; a `starting` handle has
 * no session id yet (the child may not exist), so it is skipped with a
 * debug log rather than guessed at. Remote handles are out of scope —
 * documented gap: remote children survive parent termination until a
 * remote-termination protocol exists.
