The matrix skipped itself on every PR: pr-checks.yml never fetched the
baseline tags and never set DSH_REPO, so skipReasons() always reported a
missing checkout and describe.skipIf dropped the whole per-baseline block —
the registry apply, the wire keys, the checkpoint JSON gate, cold restore
and every client seam probe. Only the release workflow fetched them, so
the compatibility proof compatibility.md claims for "every pnpm test" was
a no-op until a tag was cut.
Both workflows now fetch the tags and export DSH_REPO, and a skip under CI
fails the run instead of hiding behind green: a missing prerequisite there
is a broken gate, not an absent one. The two test runs collapse into one,
which also brings the lint gate the release workflow had and PRs did not.
The matrix's own vocabulary guard compared a hand-copied constant against
hand-copied baseline lists, so it could never see a drift in the fold — and
had drifted: approval/asked, approval/decided and session/end-seed are
folded but declared by no baseline. It now reads the fold's case labels out
of src/host/fold.ts, so a new fold case cannot go unprobed, and the history
probe pins the `records` envelope historyPage's rowsOf rejects without, not
just the remote's service name.
