# MI9 - Micro-Copy Localisation (i18n Keys and ICU Messages)

## Module
Web

## Status
VERIFIED

## Description
Full micro-interaction localisation file with EN defaults covering all interaction states (loading/skeleton/progress, error types, offline banners, toast/undo, actions, validation, accessibility labels, motion preferences). i18n service exists for key resolution.

## Implementation Details
- **Feature directory**: `src/Web/StellaOps.Web/src/app/core/i18n/`
- **Services**:
  - `i18n` (`src/Web/StellaOps.Web/src/app/core/i18n/i18n.service.ts`)
- **Source**: Feature matrix scan

## E2E Test Plan
- **Setup**:
  - [ ] Log in with a user that has appropriate permissions
  - [ ] Navigate to the relevant page/section where this feature appears
  - [ ] Ensure test data exists (scanned artifacts, SBOM data, or seed data as needed)
- **Core verification**:
  - [ ] Verify the component renders correctly with sample data
  - [ ] Verify interactive elements respond to user input
  - [ ] Verify data is fetched and displayed from the correct API endpoints
- **Edge cases**:
  - [ ] Verify graceful handling when backend API is unavailable (error state)
  - [ ] Verify responsive layout at different viewport sizes
  - [ ] Verify accessibility (keyboard navigation, screen reader labels, ARIA attributes)
