3 sessions on grub with a coding agent: the agent failed at least once in 1, and 2 finished without a human stepping in.
Takeaway: I'd start the next audit by explicitly telling it to re-verify the NEVER DO list against reality before touching anything, since two of the entries there turned out to be stale (pacnew notes, BIOS assumption).
Takeaway: Next time I'd specify upfront that MB1 must stay fully working as a real fallback, not just compile — that black-screen/no-console debugging loop cost the most time.
Takeaway: I'd start the next prompt by telling it to always check the NEVER-DO list for staleness before treating any entry as gospel — that's what let us safely revisit both the mkinitcpio hook and the 'never update BIOS' rule instead of leaving good gains on the table.
