Representative scenario
A design choice that was sensible during construction creates an access, identification, or documentation question for a technician years later. The original reasoning is no longer close at hand.
The technician now needs both the physical asset and the context behind the decision.
Carry intent forward
Preserving design intent, field changes, access details, and later lessons gives future workers more than a static drawing. It gives them a way to understand what they are seeing.
This is a representative scenario, not a claim about a specific design or outcome.
