main has been red since 4f7b4e3 for a reason visible nowhere in its diff.
The player-parity baselines describe what an UN-UPDATED display can do, so
they are judged against the SHIPPED source — `git show <latest tag>:…` —
rather than the working tree. actions/checkout defaults to a shallow clone
with no tags, so that lookup found nothing and the suite fell back to the
working tree. In a tree where today's QA had just fixed the players'
set_volume payload bug, the biconditional then demanded that
BASELINE.web/tizen gain audio.volume — for displays that cannot possibly
have the fix yet. Green locally, red in CI, and the failing assertion names
a baseline rather than the checkout that caused it.
So fetch the tags in the test job, and make the biconditionals SKIP when
there are none instead of asserting against the wrong source. That fallback
was never a slightly-early assertion; it was an inverted one. A skipped
assertion announces itself, a wrong one does not.
Verified both ways: with tags 15/15 pass, in a tagless shallow clone 13
pass + 2 skip + 0 fail (previously 1 fail).
