This looks solid to me! We might need to update the ticket and keep it open or add a new ticket to integrate this further with the "run lg on server" story. Our ultimate goal will be that this story will not just perf test main, but also generate the report to diff against the last commit. As it is right now (which is great), we're just perf testing main and will need to manually diff against the previous commit.

• Filed this ticket to update our slackbot.
• Filed this ticket to generate a report against the previous commit and post it in the slackbot.

A few Slack message suggestions and next step suggestions but otherwise looks good to merge.
