What
The upload that hands your work to a remote session checks for cancellation around bundling, environment resolution and the network request itself, so cancelling no longer waits for the whole upload. The caller is also told when the request has been sent.
Details
A progress callback fires with request_sent at the point the log line [teleport] phase: POST-sent is written.
Applies to every remote handoff; not gated.
Evidence
[teleport] phase: POST-sent
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
