Implemented only the P1 lifecycle finding from the approved PR #481 review, preserving the requested one-fix-at-a-time commit boundary.
git diff HEAD~1..HEAD -- tractor/runtime/_supervise.py
Added per-child reap request/completion events to ActorNursery, a shielded child-specific cancel-and-reap operation, late-registration latching for nursery teardown, and cancellation escalation that waits for debugger release before using non-ignorable process termination. The nursery-wide cancellation path snapshots child records before checkpointing so concurrent one-shot cleanup cannot invalidate its iteration.
git diff HEAD~1..HEAD -- tractor/spawn/_trio.py
Changed Trio child monitors to wait on their per-child reap requests.
git diff HEAD~1..HEAD -- tractor/spawn/_mp.py
Changed multiprocessing child monitors to wait on their per-child reap requests.
git diff HEAD~1..HEAD -- tractor/spawn/_spawn.py
Ensured every backend publishes child-reap completion after its process monitor exits.
git diff HEAD~1..HEAD -- tractor/to_actor/_api.py
Changed owned one-shot cleanup to await child-specific process joining and bookkeeping removal instead of treating the cancel RPC as reaping.
git diff HEAD~1..HEAD -- tests/test_to_actor.py
Added regressions for immediate caller-managed nursery cleanup, failed cancel acknowledgement escalation, and child registration after a latched nursery-wide teardown request.

One broad verification run was mistakenly launched in parallel with the UDS and mp_spawn actor suites. It timed out test_remote_error_from_caller_nursery; the node passed immediately in isolation and the complete broad selection then passed serially. The failure was classified as concurrent test-session interference, not accepted as a passing boundary result.
Ruff, Python compilation, and git diff --check passed for the changed boundary. Ruff’s existing _trio.py F401 finding was reproduced at the unmodified PR head and excluded from attribution to this patch.
