+# V13-FE-004 — Provider Adapter 구현 재검증

+
+## Source / Assumption / Unknown / Decision Required
+
+- **Source:** PrimeVue/AG Grid imports are confined to the approved adapter directory; `Ks*` components consume `UiAdapter` rather than provider components.
+- **Assumption:** the existing WCAG 2.2 AA target is the applicable baseline; this test run is contract-level evidence, not an assistive-technology audit.
+- **Unknown:** provider visual baseline and keyboard/AT matrix remain pending `AEG-V16-024` approval.
+- **Decision Required:** no new provider or provider-specific component is introduced by KBX reuse.
+
+## Actual evidence
+
+`pnpm vitest run src/shared/ui/adapter/tests/uiAdapter.contract.spec.ts src/shared/ui/components/tests/accessibility.contract.spec.ts`
+
+- 2 files / 4 tests passed
+- exit 0, 2026-08-09
+
+No DB, migration, end-to-end, visual baseline, or screen-reader pass is claimed.
