			=Underlying Capability Stack=

			Each stage progressively develops:

			* Precision machining
			* Bearings and seals
			* Rotor balancing
			* CFD and fluid dynamics
			* Thermal systems
			* Materials science
			* Sensors and instrumentation
			* Control systems
			* High-speed rotating machinery
			* Reliability engineering
			* Manufacturing QA
			* Integrated systems engineering

			The progression is cumulative.

			Each stage builds industrial competence required for the next stage.

			=Strategic Insight=

			The true bottleneck is not merely turbomachinery design.

			The bottleneck is the creation of integrated organizational capability across:

			* manufacturing
			* testing
			* metallurgy
			* controls
			* instrumentation
			* documentation
			* operational learning
			* rapid iteration

			Open-source turbomachinery development therefore requires not only open designs, but open capability formation systems.
