- Vault home (#12): recursive file listing (rglob), rel_dir in metadata, 'recursif' badge, updated roadmap description - Backup viewer: fix close button (inline onclick + event delegation fallback for text nodes), improve error messages - Backup API: remove response_model to prevent Pydantic 500 errors, add try/except + logging on backups/diff/restore endpoints, per-entry error handling in _list_backup_files, encoding safety (errors='replace') on read_text - AI status: call /api/ai/status at startup in _initAIStatus instead of waiting for user click on sync badge
