Populating a repaired wind-turbine pitch controller in the bench oven, a technician loads the profile verified last month on a thin sensor board: 'a verified oven profile is verified — the oven doesn't care what's in it.' What does the section correct?

Select one answer.

• Only the age — oven profiles expire monthly regardless of board, and the re-verification calendar was the actual miss.
• Nothing — the zone map absorbs board differences, which is precisely why the section requires the map before any card is trusted. The map already measured how the oven behaves under load across the mass range the bench runs, the load-compensation reasoning map-first shops rely on: stages defined against measured behavior flex with the board on the belt, which is exactly the portability that makes mapping worth the runs — one oven biography serving every card in the drawer, light boards and heavy alike.
• The card's scope: an oven profile is verified for a board class, and the class is defined by its thermal extremes. The thin sensor board's window was set by its own coldest and hottest points; the thick controller brings heavier masses that will not reach wetting on stages tuned for a light board — or will demand dwell the light components' ceilings cannot give. One flight serves every joint, so the card must be verified over this class's extremes, not borrowed across classes.
• The instrument — controllers with heavy copper are never oven jobs, and the section routes all thick boards to the station's targeted heat.
