New _reap_ria_portals(an, errors, ria_children=None) helper (one _spawn.cancel_on_completion() task per ria child under collapse_eg() + a local nursery); run_in_actor() drops nursery=self._ria_nursery; happy path awaits the reap right after ._join_procs.set(); inner error handler snapshots ria pairs, runs await an.cancel() then a move_on_after(0.5)-bounded reap over the snapshot.

git diff a34aaf98..wkt/to_actor_subpkg -- tractor/spawn/_trio.py git diff a34aaf98..wkt/to_actor_subpkg -- tractor/spawn/_mp.py

Both backends: the post-_join_procs block collapses to a bare soft_kill() (membership branch, per-child reaper nursery, reaper-cancel logging and the now-unused cancel_on_completion imports all removed).

Agent-verified machinery map, 3-step design (A/B/C), probe history (deadlock -> sequencing fix -> bound tightening) and risk register.

tests/test_to_actor.py + tests/test_spawning.py: 20 passed
full-suite (SIGINT at 540s bound, ~30s short):

Failed intermediates (not in final diff): concurrent reap+an.cancel() deadlocked test_multierror; a 3s reap bound blew test_cancel_while_childs_child_in_sync_sleep’s fail_after deadline.
