Research
Cases with a cited primary source and a quality rating — charts calculated by the engine validated against NASA and JPL.
Methodology: a case only enters with a cited primary source, classified by the quality rating (AA civil registry · A person/family · B biography · C no clear source · DD conflicting · X no time). A case without a time stands without Rising and without houses — and the reading says so. The collection grows by curation, not by scraping.
