Locales FR / ZH / AR Report

Locales FR / ZH / AR Report

Coverage

• Frontend leaf-key count: en=913, fr=913, zh=913, ar=913
• Backend leaf-key count: en=235, fr=235, zh=235, ar=235
• Placeholder mismatch check: 0 mismatches for fr, zh, and ar versus en in both frontend and backend
• Note: the active en.json baseline on 2026-04-23 already contains 913 frontend leaf keys, so the older CX spec number 887 is stale for the current tree

Angle Markers

• No <angle> review markers remain in app/frontend/src/i18n/{fr,zh,ar}.json
• No <angle> review markers remain in app/backend/app/i18n/{fr,zh,ar}.json

RTL Audit

• Replaced with logical properties:
• app/frontend/src/styles/layout.css: left -> inset-inline-start
• app/frontend/src/styles/components.css: padding-left -> padding-inline-start
• app/frontend/src/components/Accordion.module.css: text-align: left -> start
• app/frontend/src/components/EmptyState.module.css: text-align: left -> start
• app/frontend/src/components/MetricCard.module.css: margin-left -> margin-inline-start
• app/frontend/src/components/SidebarPanel.module.css: left / padding-left -> inset-inline-start / padding-inline-start
• app/frontend/src/components/ToastSystem.module.css: right / border-left -> inset-inline-end / border-inline-start
• app/frontend/src/components/ResultsPanel.module.css: border-left* -> border-inline-start*
• app/frontend/src/components/WizardDraftStep.module.css: margin-left -> margin-inline-start
• app/frontend/src/components/results/WarningsSection.module.css: border-left* -> border-inline-start*

Left As Physical Coordinates

• app/frontend/src/components/ForestPlot.tsx: kept left/right inline positioning because they encode chart coordinates, not page direction
• app/frontend/src/components/ComparisonDashboard/DistributionView.tsx
• app/frontend/src/components/SequentialBoundaryChart.tsx
• app/frontend/src/components/PowerCurveChart.tsx
• app/frontend/src/components/PosteriorPlot.tsx

These remaining left/right hits are Recharts margin values or plot-coordinate positioning and were intentionally not converted to logical properties.

A11y

• npm run test -- src/i18n.test.tsx src/test/a11y-locales.test.tsx src/test/a11y-rtl.test.tsx passed
• src/test/a11y-rtl.test.tsx confirms document.documentElement.lang === "ar" and document.documentElement.dir === "rtl"
• axe reported 0 critical/serious violations in the targeted de, es, and ar+rtl switcher renders
• Vitest/jsdom still prints the known HTMLCanvasElement.getContext() warning during axe runs; it does not fail the suite
