Frozen launch-system census
The registry connects every included launch to a configuration while preserving 66,794 individual stage objects and refusing to infer retirement or reuse from incomplete evidence.

individual flown stage objects
All 26,995 GCAT launches inside the space-only boundary map to a configuration record and its frozen flight history.
Last use and recent activity are dated evidence. Neither becomes an unsupported claim about retirement or future availability.
583 repeated serial groups are review leads, not automatic physical-identity merges.
Reader-facing rollout
All 5,615 family, configuration, stage, and engine designs now have shared-contract cards and stable detail pages. All 66,794 physical stages remain exact parent-linked rows, loaded only when requested; 500 references to 32 source-only fairings, adapters, reentry vehicles, payload sections, or engines are counted without inventing target pages.
