Selected, candidate, assigned, backup, cancelled, and unflown identities never become completed spaceflights merely because they appear in a space program.
Current affiliations are not projected backward. Organization relationships retain the cited wording and preserve missing dates as evidence holds.
The archive excludes private contact, family, medical, financial, and unrelated personal information and preserves identity uncertainty instead of merging by name.
All 271 organizations now have searchable shared-contract cards and stable archive detail routes. The archive connects 80 organizations to 493 launches through 791 exact canonical mission relationships, and all 110 organization labels across the 47 reviewed contributor profiles resolve exactly to canonical routes. It does not infer institutional responsibility from a matching operator label.
The card contract labels 44 organizations source-backed because they expose both a reviewed source and a meaningful mission, launch, or contributor relationship. The other 227 remain evidence holds at this presentation boundary; 27 of those are the narrower source-discovery holds recorded by the institutional census. A source-only identity can still be browsed, but it is not presented as a fully connected history.
