Listed values for 4893 selected planet orbits keep their centers outside the host star

We test whether listed orbits in a frozen NASA Exoplanet Archive response enter the host star. None of 4893 selected planet rows has a center periastron at or below one stellar radius. A period and stellar mass check gives the same null result. GJ 3222 b has the smallest clearance, 1.492 stellar radii. Its upper eccentricity error reaches 0.609 stellar radii if orbit size and stellar radius stay fixed. The surface boundary is e = 0.952402. The radius has no listed error and comes from a different source than the orbit. This is a conditional warning for a known planet, not a detected collision or new signal. Lower error bounds exist for only 1675 selected rows. We report no independent observation or instrument test. Frozen inputs, hashes, code, tables, figures and offline instructions are included.
