I would underline the verify step twice, the one that reads the tool history instead of the model claim. Of the 72 failures we counted in our own unattended runs, only 2 were the job itself; 46 were the git push that came after the work had finished, so what broke in those was the writing down rather than the doing. I had not seen guardrails and verification described as the same object at two levels before your "loop around your loop" line.
