74 | O'Neill-style cylinders¶
Bottleneck¶
Industrial scale, ecology, governance
Backchain¶
- Foundations I: W1 dynamics/systems
- Foundations II: W2 structures/ecology/manufacturing
- Specialization: Space industry and off-world systems
First proof of work¶
Cylinder dependency graph + structural/ecology budget
Connected study¶
Editorial study connections grounded in the existing technology bottlenecks and subject descriptions. Background is useful preparation, not a validated prerequisite or a complete technology curriculum.
Specific subject connections have not been mapped yet.
