| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Classical Monumental Construction (construction) | common_dependency | 54% | expert_inference | A clean room is a controlled built workspace, but generic construction is contextual infrastructure rather than the core laminar-flow principle. |
|
| Filters & Membranes (Early) (filters_membranes_early) | required | 86% | textbook | Whitfield-style clean rooms require highly filtered air sweeping through the workspace to remove particulates. |
|
| Air Conditioning (air_conditioning) | enabling | 62% | expert_inference | Controlled airflow and ventilation practice enabled modern clean-room environmental control, without making general air conditioning the defining invention. |
