Thank you! This looks good to me.

I'd love it if @malhotra5 can take a look too. The goal, as I understand it, is to not set the runtime image to the released version, so that it rebuilds it from the latest main when run on experimental.

Thanks so much for doing this! There's a couple of minor changes I'd like to address, and will leave the comments in a couple of hours from now

Overall looks great! Just the workflow definition needs a little tweaking

It seems moving the env variables to echo statements causes a regression that #5641 and #5897 addressed; could we move them back to the original env statements?

Here is a sample test logs that showcase the failure

I added it back, can you have a look again?
