Keep the old laptop unchanged while you do it. Its working setup is the reference you actually have, even if nobody documented it properly at the time. Also retain the complete error, not just a paraphrase saying SDK problem.

Error saved. Imported locations differ between laptops; checking the method signatures next. No controller changes made.

Are both launched the normal way? A terminal may select another interpreter from the one the training shortcut uses.

And keep local argument validation separate from the connection test, because solving a call mismatch doesn't yet prove the replacement environment reads or interprets the controller response correctly.

One comparison used a terminal, not the shortcut. I'll repeat the imported-path check from the actual launch.

That could explain why the folder search was confusing without telling us which version is suitable. Document both launch routes and ask whoever maintains the training environment to select the intended supported setup, rather than delete copies until something happens to run.

Hazel, I agree about selection, but the handover needs an owner as much as a package version. Who will update the shortcut and record the test when the next class laptop is rebuilt?

Training technician owns it. Actual shortcut imports a different copy again. Its signature doesn't match our unchanged call.

That gives you an observed mismatch. I would keep the other copies as evidence until the technician has finished the comparison, rather than tidy them away now.

Can the technician tie the selected version to its documentation and the documented read-only exercise, so the next handover doesn't merely preserve another unexplained working folder?

And record the normal working directory or other launch context if it affects imports. The goal is a repeatable launch, not a command that succeeds only while Gabriel happens to be standing in the right folder.

Technician has selected and documented the supported environment. Shortcut updated; argument rejection gone. Response check still to do.

Keep that last sentence on the status note. People hear fixed and schedule the training exercise, while you have only established that the local call is now accepted by the intended interface.

Will the response check use the ordinary training account as well? That would cover more of the real launch than the technician's account alone.

Agreed. Same documented read-only exercise, normal account, response checked against the selected interface documentation. Scheduled, not completed.

After it passes, keep enough detail to repeat it: launch, imported path, version, expected interpretation and observed result. No need to turn it into a motion trial to close an environment mismatch.

Normal-account check passed. The response was interpreted correctly, and the launch details are in the rebuild note.

Then you can close this mismatch with a defined test boundary; it establishes the restored read-only exercise, not every possible operation somebody might later add to the cell.

Closed on that basis. Thanks, Omar; checking the shortcut exposed the copy our terminal comparison had missed.
