Research direction

Search the Rust repository for the warning text "Activity not found on completion" and trace the completion path used after an activity cancellation. Reproduce the described start-cancel-wait-workflow-return scenario, then verify that the warning is suppressed or logged at a lower level specifically for cancellation while other missing-activity cases retain their existing behavior.

Written by the indexing model from the issue text.

Description

enhancement
Is your feature request related to a problem? Please describe.

If I just start an activity, cancel it, and wait on the task (which has TRY_CANCEL by default), and return from the workflow I get this warning:

Activity not found on completion. This may happen if the activity has already been cancelled but completed anyway.

At least I believe that is what is happening.

Describe the solution you'd like

Don't show that log if this is an activity cancel since sometimes it is the workflow leaving that is causing the cancel (and other times the workflow may be gone for other reasons). Or maybe reduce the log level.
