summary: Does this manual or procedure apply to this unit?
description: 'Checks whether a manual, service bulletin or procedure applies to a specific unit by comparing the scope the document declares (models, firmware or revision range, serial range, exclusions) with the unit''s facts the caller supplies. Versions written as dotted digits (2.10.1) compare numerically per segment. For an agent about to follow a repair or configuration procedure. Applicable only when every declared scope field is shown to match; a unit fact that is missing is unknown, not applicable. Does not read the manual or look the unit up.
Price: 0.005 USDC on Base (x402).'
