UI8 closes the migration cycle started by UI0. The four legacy global
classes (.surface-card, .surface-muted, .badge, .input-shell) are
removed from web/src/app/globals.css and the CI ratchet now enforces
zero new occurrences across three of the four drift categories.
Changes:
1. Audit regex precision (scripts/ui-drift-audit.sh, scripts/ui-drift-ratchet.sh)
The previous pattern 'className="[^"]*(badge|surface-card|surface-muted|input-shell)'
matched the literal token anywhere inside className, which caused 21
false positives against Tailwind arbitrary values like
'bg-[color:var(--nl-surface-muted)]' where the legacy name appears
inside a 'var(--nl-...)' reference.
New pattern requires the legacy class to be a whole class token —
either at the start of className, or preceded by a space, and
followed by a space or closing quote. Result: 21 false positives
eliminated; the ratchet now reports an honest 0 for the legacy
category.
2. globals.css cleanup (web/src/app/globals.css)
Removed .surface-card, .surface-muted, .badge, .input-shell rules.
Only truly global utilities remain (typography, focus-visible,
sr-only, skip-link, motion preferences, layout grids). A header
comment documents that re-introductions should be solved at the
call-site with a primitive, not by restoring the global rule.
3. Ratchet baseline (scripts/ui-drift-baseline.json)
Final counts after UI5–UI8 across the session:
raw interactive controls 14 (was 38 at start)
legacy global surface classes 0 (was 92 at start)
hardcoded color literals 0 (no change, was already 0)
direct @bytelyst/ui imports 0 (no change, was already 0)
The 14 remaining raw controls are intentional and tracked:
NoteEditor toolbar buttons (10)
ArtifactPanel hidden file input (1)
search/page radio inputs (2)
NoteVersionsPanel disclosure button (1)
4. CI gate (.github/workflows/ci.yml release-guards job)
Documented that the ratchet is the canonical gate post-UI8: because
legacy/colors/imports baselines are 0, any new occurrence in those
three categories now fails CI. The strict-audit script is kept as
a local diagnostic tool but not wired as a gate (would fail on the
14 intentional raw controls).
5. Roadmap (docs/UI_UX_PLATFORM_CORE_ROADMAP.md)
Marked UI5, UI6, UI7, UI8 all complete with per-phase commit hashes
and explicit deliverables.
Cumulative migration impact (from initial baseline):
raw interactive controls 38 → 14 (-24, -63%)
legacy global surface classes 92 → 0 (-92, -100%)
Verified:
- pnpm run verify: backend 380/380, web 96/96, mobile 97/97
- bash scripts/ui-drift-ratchet.sh: all four categories at baseline
- bash scripts/ui-drift-audit.sh: only "Raw interactive controls"
category has matches (intentional, tracked above)
- Live Docker stack at http://localhost:3050 still serves 200,
backend health 200
- Providers.tsx now calls initFeatureFlags() and checkKillSwitch()
on mount (both were wired but never initialized).
- globals.css: replace hardcoded #0b1020 with color-mix() from canvas token.
- layout.tsx: make themeColor responsive (dark/light media queries).
- use-theme.ts: prefix localStorage key with PRODUCT_ID for consistency.
