+
+Refactor codebase to align with copilot-instructions.md guidelines
+
+**Architecture Changes:**
+
+- Restructured to Component-Hook-Model (CHM) architecture
+- Created `src/core/` for framework-free pure functions (validator, conditional, schema-helpers)
+- Created `src/models/` for TypeScript contracts with zero runtime logic
+- Restricted public API exports in `src/index.ts`
+
+**Accessibility Improvements:**
+
+- Fixed RadioGroupField to use proper `role="radiogroup"` with `aria-labelledby`
+- Fixed SwitchField to use proper `role="switch"` with keyboard support (Enter/Space)
+
+**Bug Fixes:**
+
+- Fixed `handleSubmit` to mark fields with errors as touched on validation failure
+- Fixed `useAsyncValidation` to properly handle DOMException AbortError
+
+**Testing:**
+
+- Added comprehensive test suite with 192 tests
+- Achieved 80%+ coverage: 94.64% statements, 83.77% branches, 83.33% functions
+- Coverage tests for core/, hooks/, and components/
+
+**Documentation:**
+
+- Enhanced JSDoc for FieldType enum values
+- Enhanced JSDoc for ConditionalOperator types
