Briefing
Sam Rivera spent yesterday morning on a retry change for transient checkout errors, and it passed the checkout suite.
The release build runs from main this morning, and main does not have the change.
The workspace Sam was using is still open on this host, untouched since.
Dev's instinct is to copy the one-line change into a fresh commit on main by hand, which would ship code the checkout suite never saw.
The fix is yours to find: hints, the recovery checks and the debrief unlock inside the incident.
