Process Notes / 014
The cleanroom is a design system, not a costume
What a night shift beneath the filter grid taught me about disciplined interfaces, deliberate silence, and the value of a visible rule.
At 02:10, the bay is all pressure and repetition: white sleeves, blue panel light, a floor clean enough to reflect the ceiling grid. Every label has a place because ambiguity costs a run, not merely a moment of attention.
A rule should make the next move obvious
Last winter I watched an operator stop at a tool cabinet without asking a single question. The panel hierarchy had done its work before she arrived: status first, instruction second, exceptions isolated at the edge. That is not austerity. It is care made legible.
