 "symptom": "The agent put the board into BOOTSEL successfully, then hit a wall on every reflash path: /dev/sdX was root:disk 660, `udisksctl mount` returned NotAuthorizedCanObtain because the arm session has no seat for polkit to treat as locally active, picotool could not open the raw USB node, and there was no sudo. Reflash success rate 0/10 \u2014 a permissions result, not a hardware one.",
