A NAS box's case file is the strongest a bench could ask for: warm-up intermittent interviewed, meters convicting an open at the controller's die-shadow region, a swing test toggling at a logged forty-two degrees. The technician books the reball for tomorrow morning. What does the section say is still missing?

Select one answer.

• Nothing — a three-instrument conviction is the chapter's definition of an earned yes, and the remaining questions answer themselves during the removal the reball begins with anyway.
• The fourth instrument — a radiograph confirming the crack's geometry belongs in the file before any rebuild is scheduled, since reballs planned without imaging routinely rebuild the wrong region.
• The gates: the toggle convicted the fault, not the patient. The pad gate needs board-side evidence — and where the file is silent, it waits for the removal's direct inspection rather than passing on assumption; the silicon gate needs the meters' vital signs read as a verdict; and the class gate needs the construction checked — underfill or stacking moves the job off this bench. Three written lines, each citing evidence, before a sphere is counted.
• The budget only — the gates are implicit in a file this strong, but the exposure count and the moisture line still need writing, and the booking stands once those two numbers land in the quote. The gates formalize what a file this strong has already demonstrated in substance, which is why budget-first sequencing is the working norm on three-instrument convictions. It is also the sequencing the schedule prefers, since budget lines are desk work tonight while gate paperwork would push the booking a day for verdicts the instruments already implied.
