I appreciate the postmortem! I don’t think “looking more carefully” scales, though - I think we should be aiming for automated ways to make sure there’s a match between the data being tested and what’s being voted on.
We’ve long had issues with the manual workflow involved in putting a proposal through. My own opinion is that we should start to use Tally’s draft function (or any equivalent through another governance portal), and to only number EPs when they get posted onchain. By doing that, it’d be easy for Blockful and others to verify the payload of Tally drafts, and it’d also be easy to set up an automated process that detects new onchain and Snapshot votes and automatically creates PRs for them, while assigning them an EP number.
