The archive leaves sy_dist blank for mu2 Sco and publishes sy_plx 6.31 +- 0.86 mas. The matcher
only reads the parallax as a second chance beside a finite sy_dist, and the archive-star fallback
needs sy_dist too, so mu2 Sco b had no host while Pipirima (HIP 82545, V 3.56, B2 IV) sat on the
map 0.4" from the archive's direction at 145.3 pc. The build.ts comment and the step report said
the 27 hostless planets had "no distance in either archive table"; mu2 Sco was the one whose row
has a parallax.
archiveDistancePc takes sy_dist, or 1000 / sy_plx where it is blank (158.5 pc here, within the
ratio test of Pipirima's 145.3). An ETL run from cache changes exoplanets.json alone: mu2 Sco b
now has host 82294, Pipirima, and 6 328 of 6 354 planets have a host (26 without, none of whose
rows has a distance or a parallax). hostDistancePc stays the archive's own blank.
Control: ignoring the parallax fails "takes the archive's parallax where it gives no distance,
and nothing from a parallax that is none" alone.
