Artifacts

1. Validate display, mapping and limit in LiveTileService::validateSourceConfig(). Verify: PHPUnit for each rule and for an old config.
2. Evaluate the mapping server-side for both source modes, drop unmapped fields, apply the limit, and cache the mapped result. Verify: PHPUnit with array and object payloads.
3. Render list, table and key-value in LiveTileWidget.vue, with https-only links and accessible markup. Verify: Vitest and an axe check.
4. Add the display choice, mapping rows and the "Latest documents" preset (SharePoint and Confluence variants) to LiveTileWidgetForm.vue, and rename its "OpenConnector" labels to "Integriq". Verify: Vitest.
5. Playwright: a URL-mode list tile against a fixture endpoint.
6. Add nl and en strings, fold the delta into openspec/specs/live-data-tile-widget/spec.md on archive, and set int-builder and int-intranet-content to built in the parity matrix with evidence lines.
