Sources & what still needs checking

Reviewed 2026-10-06. Each claim has its own evidence and version note above. We still need current machine-panel rates, post-Update 5.5 rocket-console footage, and skill-panel footage for CO2 Reactor Tank. No production timing is calculated from unverified figures.
