Surface + problem playbook
Authority graph: primary / compatible surface + problem playbook.
primary framing for water spotting (evaporation film) on fixtures.
Neutral first; escalate only with label checks and spot tests.
Water spotting (evaporation film) appears on fixtures when the surface conditions, environment, or maintenance pattern allow that problem type to develop or remain visible.
The biggest mistake is treating the visible issue without checking whether the surface is sensitive to the chemistry, abrasion, or moisture involved in removal.
The process should protect the finish, control residue, and avoid turning a contamination problem into a surface-damage problem.
