A clean-looking wall has unresolved surface evidence

A fictional decorating contractor is asked to repaint a wall that looks uniformly white from the doorway. A cloth leaves a powdery mark, several small edges lift during an appropriate preliminary inspection, and the client reports an earlier roof leak. The current moisture status and existing coating type have not been established. A supervisor proposes applying a high-build primer immediately because it will hide the different patches. The project has not authorized disturbance of potentially hazardous old material. This written exercise performs no sampling, stripping or sanding. The team must distinguish appearance from substrate acceptance, decide which evidence is missing and preserve the proper scope of a primer rather than treat it as a repair for every possible failure.
