UI8 deferred deleting the legacy global classes (.surface-card,
.surface-muted, .input-shell, .badge) because 69+ call sites in UI6/UI7
territory (dashboard, search, workspaces, notes detail, chat, palace)
still depend on them. Removing the globals before those screens migrate
would visually break the app.
Instead, ship a one-way ratchet that solves the actually-important
problem: prevent NEW legacy usage from creeping in while existing
sites get migrated.
- scripts/ui-drift-ratchet.sh — reads scripts/ui-drift-baseline.json
and FAILS if any of the four UI drift categories regress above the
tracked baseline. Pure bash, no jq required, works with grep or
ripgrep. Uses the same patterns as scripts/ui-drift-audit.sh.
- scripts/ui-drift-baseline.json — checked-in baseline captured today:
raw controls 38, legacy classes 92, hardcoded colors 0, direct imports 0.
- package.json — adds pnpm run audit:ui:ratchet and
audit:ui:ratchet:update scripts.
- .github/workflows/ci.yml release-guards job — runs the ratchet as a
required step plus the existing audit in report mode.
- docs/UI_UX_PLATFORM_CORE_ROADMAP.md — marks the CI-guard checklist
item complete, documents the path to fully strict mode (drive
baseline to zero, then delete globals.css legacy classes, then flip
audit:ui:strict from advisory to required).
Verified:
- Ratchet at baseline: exits 0
- Synthetic regression (added a file with surface-card + raw <input>):
ratchet correctly exits 1, reporting +1 in each affected category
- pnpm run verify: backend 380/380, web 96/96, mobile 97/97 (no
behavior change)
