Biology, microgravity, general science, technology and training, education, and calibration classifications define the object boundary.
A technology label identifies a catalog purpose. It does not prove that a demonstration worked, reached readiness, or became operational.
Dataset, experiment, report, publication, version, access, and rights identities remain native to the responsible science or technical archive.

One checksum-bound directory presents 5,188 canonical science records, including 24 science archive authorities, 127 Earth-data collections, and 14 controlled subjects. It adds 822 new long-lived detail records while reusing existing observatory, instrument, and topic routes.
The first enrichment cohort gives all 5,188 cards bounded record-specific summaries and exposes 2,922 readable public source links on the new detail records. Compact-index and compressed-detail sizes remain checked by the generated presentation and production build budgets. Specialist product, observation, proposal, and publication identities remain native to their responsible archives.
