6d81c45 set ARCHIVE_EPOCH to Gaia DR2's 2015.5 and tested the constant's value, through
propagateProperMotion; nothing tested that resolveHostStarId uses it. The review's mutant that
carried the matcher's queries back from 2016 passed 807 of 807, since the GJ 15 A fixture's decoy
sits 16″ away and half a year moves the query 1.5″ there.

A new case gives resolveHostStarId Barnard's star's archive row (the J2015.5 position and motion
the epoch test already uses) and three stars: Barnard's at the row carried back 15.5 years, and
decoys where carrying it back 16 and 15 years lands, 5.2″ either side at its 10.4″/yr. It must pick
Barnard's. Controls: the matcher carrying back from 2016, or from 2015, each fail it.
