Editorial boundary: This public alpha is generated from version-controlled source without third-party application or build packages. It is not the reviewed 1.0 corpus: 60 Academy lessons are substantive editorial drafts, 0 remain foundation outlines, and independent domain review remains open.
Current state
- Polymer printing, sample metal printing, welding experiments, robotic servicing, and limited recycling have flown.
- Ground programs are advancing regolith excavation, oxygen/metals extraction, large structures, and autonomous manufacturing cells.
- No end-to-end autonomous chain exists from mixed waste or ore to a certified installed critical part.
Major unknowns
- Semiconductors, bearings, seals, lubricants, catalysts, precision optics, tools, and calibration standards remain vitamin inputs.
- Recycled feedstock can hide contamination and property drift without extensive metrology and nondestructive evaluation.
- Century-scale process equipment must itself be repaired using locally available processes and knowledge.
Failure modes
- Feedstock contamination, metrology drift, missing tooling, or an irreplaceable machine stops multiple repair chains.
- A printed part matches shape but not material properties, certification evidence, or lifetime under the real load.
Useful precursors
- Orbital servicing, station additive manufacturing, terrestrial remanufacturing, and repairable-product standards.
- Lunar and asteroid resource demonstrations that publish full excavation, beneficiation, energy, and spares balances.
Decision gate
Operate an integrated factory cell through tool wear, sensor drift, contaminated feedstock, missing specialists, and injected cyber faults.
Claim records
- A worldship needs a circular industrial ecosystem, not a large 3D printer; the factory must maintain the factory and qualify every replacement. (normative · breakthrough-dependent · supported; 1 independent reviewer required; current review: pending)
