Migration 0125 removed the proposer's cross-project `reference` edges, but
the write path records its by-name evidence with basis `hook`, so those
survived it. A hook edge across projects is impossible for the same reason a
reference edge is, and the write path now applies the same by-name test
(names_canon), so 0126 removes the ones written before. Judged edges keep
their own basis and are untouched.
