Replace the actor-cancel timeout watcher/status experiment with one explicit absolute deadline threaded through the existing private call path. Do not use a ContextVar, shared result state, waiter coalescing, or polling tasks.
git diff HEAD~1..HEAD -- tractor/runtime/_portal.py
Portal.cancel_actor() computes one absolute deadline and uses it for both Start frame publication and the subsequent cancel-ack wait.
git diff HEAD~1..HEAD -- tractor/runtime/_runtime.py
git diff HEAD~1..HEAD -- tractor/ipc/_chan.py
The private RPC path forwards the operation-specific deadline. Lower layers preserve the ordinary infinite-deadline call shape.
git diff HEAD~1..HEAD -- tractor/ipc/_transport.py
MsgpackTransport.send() applies the deadline inside its complete-frame shield. If the deadline expires after partial publication, it closes the unusable stream before releasing the send lock.
git diff HEAD~1..HEAD -- tests/ipc/test_each_tpt.py
git diff HEAD~1..HEAD -- tests/test_to_actor.py
Focused regressions prove a partial-frame timeout closes the stream and that actor-cancel publication and acknowledgement share one budget.
The implementation removes the earlier _SendStatus, watcher task, coalescing, shared cancel result, and per-waiter state. Four focused transport and actor-cancel tests pass.
