The answer contains a code fence.

## 2. What does supplying a project note during inference do? A. It provides current interaction context. B. It permanently retrains every future session. C. It guarantees every answer uses the note correctly.

## 3. A model gives a board pin without an exact reference. What next action fits? A. Ask two models and use the majority. B. Inspect the exact board variant pinout or schematic. C. Wire it because the name sounds familiar.
Answer and explanation Correct: B. Correct: verify the claim against the applicable primary document. - A: Agreement does not supply primary evidence. - C: A familiar family name can hide a consequential variant difference.
## 4. A synthetic invalid tuple contains 31.0 °C. Which conclusion is supported? A. The room is hot. B. The sensor cable is disconnected. C. The fixture represents invalid input; policy and physical cause need separate evidence.
Answer and explanation Correct: C. Correct: preserve validity and distinguish software rules from physical explanations. - A: The value is authored synthetic input, not a room observation. - B: A synthetic tuple cannot establish a cable condition.
## 5. The BenchNote note says invalid→FAULT and leaves recovery unspecified. An answer says “FAULT; recover after three valid samples.” Which review is right? A. Accept both because the first claim is correct. B. Keep FAULT; mark the recovery count unsupported. C. Reject FAULT because a number exists.
Answer and explanation Correct: B. Correct: judge claims individually against the supplied note. - A: Correctness of one claim does not justify an unrelated addition. - C: The validity rule governs the case; a numeric field does not override it.
