debris-class catalog identities
Frozen orbital-environment census
The archive preserves a dated debris census, fragment relationships, reentries, collisions, mitigation, space-weather history, and traffic-management milestones while directing current operational questions to the responsible live authorities.

Elements describe a historical source epoch. They are never presented as a current location, conjunction, or reentry prediction.
A shared parent groups fragments without asserting one event, cause, intent, attribution, or a complete physical population.
Tracking, conjunction assessment, collision avoidance, and space-weather alerts remain with Space-Track, operators, NASA, ESA, and NOAA.
The orbital-environment directory exposes 995 standalone records: 979 fragment-family cards, 9 milestones, and 7 authorities. Its child-row view preserves all 28,686 debris identities with catalog search and stable parent navigation.
Exactly 28,684 rows retain a sourced parent family. Two remain explicit ungrouped evidence holds rather than receiving invented parents. A historically significant child can later be promoted to a richer standalone presentation without losing its canonical child identity or family relationship.
The first enrichment cohort gives all 995 standalone cards distinct source-bounded summaries. Family descriptions now state the parent identity, member count, observed date range, and the boundary between catalog grouping and causal interpretation; live operational tracking remains with the responsible authorities.
