| Prerequisite | Type | Confidence | Evidence level | Note | Sources |
|---|---|---|---|---|---|
| Iron Working (iron_working) | enabling | 72% | expert_inference | Practical steam engines required iron boilers, cylinders, linkages, and pressure-containing parts. |
|
| Scientific Method (scientific_method) | enabling | 60% | expert_inference | Experimental natural philosophy and measurement supported steam-engine improvement, but workshop practice also mattered. |
|
| Mining (mining) | commercial_or_scaling_dependency | 70% | textbook | Newcomen engines were deployed to pump mines, making mining a major early demand and scaling context rather than the underlying mechanism. |
|
| Classical Monumental Construction (construction) | enabling | 58% | expert_inference | Engine houses, pumps, and foundations were needed for deployment, but construction knowledge alone did not create the engine. |
|
| Mechanical Clocks (mechanical_clocks) | common_dependency | 44% | weak_inference | Clockmaking is retained only as a contextual precision-mechanism tradition, not a documented hard prerequisite for Newcomen engines. |
|
| Blast Furnace (blast_furnace) | enabling | 66% | expert_inference | Blast-furnace iron production supported the heavy cast and wrought iron supply chain for early engines. |
