Switch the PR's model
Two follow-ups in, the same bug survives. Comment /switch with a configured model, and every later comment, command and Ultrafix cycle on the PR runs on it.
On its own, /switch changes the model and touches no code.
Switch models or undo a fix.
One comment replaces a model that keeps missing the point. One click, with a preview, removes a follow-up that went the wrong way. Both happen on the PR, and the next comment carries on from there.

The retry still races the timeout. Serialize the two paths and add a test that reproduces the race.
Want one run from another model and then the old one back? /use does that run; the PR keeps its model.
Open the undo link
Every follow-up completion comment carries an Undo Changes link for its commit. It opens a preview in ProPR before anything moves.
example response
Applied the follow-up. Moved the order summary below the form on phones.
Check what leaves the branch
The preview names the commit that becomes the new head and every commit that goes.
Confirm the revert
ProPR returns the PR branch to the new head. From the terminal, propr task revert does the same, with --dry-run for the preview.
Pick the lever that fits.
/switch
The model is wrong for this PR. The new one takes every later run.
/use
You want a second opinion on one run. The PR keeps its model.
Undo Changes
The last follow-up made things worse. The branch goes back to the commit before it.
See every command in GitHub comment control.
What you get
You hand a stuck PR to another model, or return the branch to where it was before the last follow-up, and ProPR records both on the PR.
