tests/baselines.ts is the single source of truth for the supported dsh
baselines and their seam faces. Three layers verify them:
- always-on host registry-contract drivers over the REAL projection
definitions (plain-JSON cache-write gate, wire delivery, checkpoint
restore, init-header tolerance) — the recurring host incidents,
- always-on client-face matrix (nodes seat, image loader service,
history face + envelope, markdown chrome, full tab render) — the
recurring client incidents,
- the `compat` vitest project: stages the REAL harness sources at each
baseline tag, boots the tag's registry on the cordis release that line
vendors, applies the BUILT plugin, and probes slots/faces/vocabulary/
platform table from the tag's sources. The release workflow fetches
the baseline tags before `pnpm test` so the matrix always runs there.
Adding a future baseline = one tests/baselines.ts entry + one fetched
tag; a failing probe names the seam to re-fit.
