# pin seam test reads to the git-refs primary

pfleidi·2w ago·1 file·+9 added/-0 removed

Removing the checkpoint_version assert left the seam test unable to
tell whether reads came from the git-refs primary or the git-branch
mirror — both stores now return identical content. Probe it directly
instead: delete the mirror's v1 branch and assert the composed store
still serves full reads, which only the primary can.
