I don't know, but here's how I'd reason

A conservation scientist examines an unlabeled paint sample. She observes a blue pigment and a cracked binder, but does not name the original workshop as fact. She calls one period plausible, marks that as an inference, and asks for a pigment assay or archive record. A lab result can revise the period expectation without turning the first answer into a failure.

In the analogy	In the answer
Blue pigment and cracked binder	Observed artifact or known fact
Plausible period	Conditional inference
Assay or archive record	Discriminating evidence
Workshop unknown	Direct knowledge boundary
Lab result	Newly confirmed fact

The analogy does not explain streaming durability or establish that a component will fail in one way. It shows why a plausible comparison remains an inference. The cited interview account supplies only the assessment context: questions probe thinking, causal explanation and adaptation rather than recalled patterns. [S2]

The local five moves make an answer auditable: boundary, observation, inference, evidence and revision. They are a curriculum scaffold, not a claimed universal interview script. The allowed sources do not prove a universal confidence formula or a mandatory verification method. A learner should use the available artifact and state the missing evidence, not manufacture certainty. [S1][S2]

A nearby fact is useful when it narrows a question without pretending to settle it. An artifact can reveal one event while leaving the component responsible for it unknown. Confidence belongs on the resulting inference, with a reason for its limit. A percentage is not a substitute for a premise, and a familiar design is not evidence that this component uses the same one. A discriminating check must be capable of separating the explanations actually under consideration. Explain how its possible findings would affect the claim.
