The implicit-runtime test verified the caller started outside Tractor
but did not prove that the target ran inside an actor or that the
private runtime was gone when the call returned.
Assert an active actor inside the shared remote target and assert the
caller has no current actor again after the one-shot call completes.

The retained-reference regression exercised generic message pointer
behavior but lived in the one-shot actor API suite and combined an
unrelated public trampoline alias assertion.
Move the pointer regression into a focused message-layer test module
and retain the alias contract as its own `to_actor` API test.

The context and one-shot suites duplicated cancellation file markers
and filtering of registrar-owned runtime contexts.
Move those mechanics into `tests._helpers` while retaining each
endpoint's distinct startup handshake. Also update the startup-cancel
`Channel.send()` mock to accept and forward the new `send_deadline` arg.

Child monitors register before their IPC handshake so cancellation
owns every started process, but the bare `None` portal arg obscured
that `Portal(chan)` replaces the provisional entry after connection.
Document that transition and name all `_register_child()` args in both
spawn backends. Replace the MP test's positional-only lambda with a
signature-accurate fake which asserts the provisional portal state.

The fresh reap-coordination maps still used legacy `.uid` tuples even
though process monitors and channels carry complete `Aid` identities.
This extended the legacy key format into new private state.
Key both reap maps by `Aid` and derive `.uid` only when accessing the
existing `_children` map. UUID-based `Aid` hashing lets the subactor
and decoded channel identities resolve the same synchronization state.
Update registration tests to exercise the full identity keys.

`._mark_child_reaped()` previously discarded the reap-request event
without checking that its completion-event peer existed. A one-sided
entry would silently lose process-reap synchronization.
Capture both pops and assert paired presence while allowing the valid
both-absent startup-failure path. Keep an unset request valid because
backend cancellation can reap immediately after registration.
Extend graceful and failed-cancel-ack runtime tests to require all
child and reap mappings empty before `to_actor.run()` returns.

A parent-side ctx cancel timeout previously bounded only the
remote `_cancel_task` ack. Complete-frame `send_all()` shielding
could hold request publication forever when a peer stopped reading.
Compute one absolute deadline and pass it through `._run_from_ns()`
so transport publication and the ack wait consume the same timeout
budget. Add a mock-clock regression which stalls the private RPC
under a nested shield and proves the transaction returns on time.

A child could pass the early `.start_actor()` guard, miss the
`.cancel()` child snapshot and register afterward. Its monitor
inherited a reap request without runtime cancellation and could wait
forever.
- publish child/reap events before sampling `_cancel_called`
- make MP abort before `proc.start()` when cancellation won
- kill a Trio child opened after cancellation won registration
- reject starts begun after nursery cancellation is already visible
- add deterministic registration and MP no-start regressions
- drop the touched Trio backend's stale `get_runtime_vars` import

A cancel RPC could stall forever in complete-frame transport
shielding before the peer received it, bypassing the outer ack
timeout and blocking graceful supervision.
- thread one absolute deadline from `Portal.cancel_actor()` through
the private `Start` publication path
- force-close a partial-frame stream before releasing its send lock
- keep ordinary sends unbounded and preserve pending cancellation
- document the current `Start -> StartAck -> CancelAck` exchange and
link the dedicated `Cancel` msg follow-up in #506
- cover partial publication and the shared send/ack timeout budget

Treat `runtime_kwargs` as provided whenever it is not `None`.
Previously an empty dict bypassed placement validation and was
silently ignored when `an` or `portal` selected an existing runtime.
Reject both placement modes before actor startup for empty and
configured runtime kwargs while preserving empty-dict use when
`to_actor.run()` owns its private runtime.

Pass target inputs positionally and normalize every retained
`functools.partial()` layer, including Python 3.14 Placeholder
binding. Validate the complete target signature before startup.
Route each ordinary async fn through a static `@context` endpoint
so remote results, errors and caller cancellation remain linked.
Send namespace and function components separately, then resolve
through `Actor._get_rpc_func()` so the RPC module allowlist remains
authoritative. Retain client-created `NamespacePath` refs so
`to_tuple()` does not re-import their callable.
Owned actors enable the endpoint's `__name__` directly. Keep
`to_actor.MODULE` as the importer-facing alias used by caller-owned
portals while retaining the target module's authorization boundary.
Cover all placement modes, nested partials, argument collisions,
linked cancellation, remote errors and authorization failures.

Give each `ActorNursery` child its own reap request and

Escalate unacknowledged cancellation with `proc.kill()` after an

checkpoints permit concurrent removal.
