 This is still taking shape. While the architecture supports it, the integration surface is still in its early stages. If you're interested in building on top of this—or have ideas about how to bridge Loominary with other AI clients—[open an issue](https://github.com/Laumss/Loominary/issues) and let's figure it out together.

+- `npm run test:ci` runs the CI-ready, non-watch test command with coverage.

+# Sprint 1 Architecture Note
+
+Sprint 1 narrows [`/src/App.js`](C:/Users/pmacl/.codex/worktrees/6c61/loominary/src/App.js) back to app composition by moving critical workflows into dedicated seams:
+
+- `src/hooks/useFileManager.js` owns file loading, parsing, metadata extraction, and merged JSONL file registration.
+- `src/services/import/fileImportService.js` provides the shared parse/process pipeline used by both file management and global search.
+- `src/services/import/conversationGroupingService.js` reconstructs JSONL branch groupings before merged import.
+- `src/services/zip/zipConversationService.js` handles ZIP import parsing plus remote ZIP sync card refreshes.
+- `src/hooks/useGlobalSearchIndex.js` centralizes index rebuild timing while `src/utils/globalSearchManager.js` stays focused on indexing/querying.
+- `src/services/export/exportOrchestrator.js` coordinates Markdown and PDF export entry points and keeps config lookup out of `App.js`.
+- `src/services/runtime/runtimeAdapterService.js` isolates browser runtime payload/session handling for extension and web viewers.
+
+The result is that `App.js` now orchestrates view state and UI interactions, while parsing, import, search, export, and runtime integration are independently testable.
