Now I have the complete picture. Let me create a comprehensive report of the error propagation chain and all types that would need to change.\n\nComprehensive Error Propagation Type Analysis\n\nI've traced the complete call chain. Here's every type that would need to change to shift from exceptions to error-as-data:\n\n---\n\n1. ROOT: DmpNhrAdapter.searchDocuments()\nFile: /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts\nLines: 145-153\n\nCurrent signature:\nasync searchDocuments(props: NhrDocumentSearchProps): Promise\n\nReturns:\n{ documents: NhrDocument[] }\n\nThrows: DMPAccessDeniedByExcededThreshold (caught at line 54 in useSearchDocuments.ts)\n\n---\n\n2.

(() => Promise.resolve({ data: [] }))}\n\n---\n\nSummary: Types Requiring Changes\n\n| Type / Interface | Location | Lines | Current Shape | What Must Change |\n|---|---|---|---|---|\n| NhrDocumentSearchResult | treatment-plan/tpf-national-health-records/business/types/api.ts | 28-30 | { documents: NhrDocument[] } | Add error/status field |\n| SearchDocumentsResult | doctolib/variants/types.ts | 5-8 | { data: NhrDocument[], total: number } | Add error/status field |\n| SearchDocumentsFn | treatment-plan/tpf-national-health-records-ui/types.ts | 58-60 | Promise<{ data: NhrDocument[], total?: number }> | Return type must include error state |\n| useSearchDocuments hook return | doctolib/hooks/useSearchDocuments.ts | 21, 33-59 | Returns SearchDocumentsResult wrapped in Promise | Must transform error from nhrOperations.searchDocuments() into result shape |\n| NhrDocumentListVariant.searchDocuments | doctolib/variants/types.ts | 13 | Function type | Signature changes to propagate errors |\n| NhrDocumentListModal state shape | treatment-plan/tpf-national-health-records-ui/NhrDocumentListModal.tsx | 30-38 | { rows, total, isLoading } | Add error/status field to accommodate errors from searchDocuments |\n| NhrDocumentListModal destructuring | treatment-plan/tpf-national-health-records-ui/NhrDocumentListModal.tsx | 46 | Destructures only { data, total } | Must handle error case in result |\n\n---\n\nCall Chain With Type Transformations\n\nDmpNhrAdapter.searchDocuments()\n ↓ Returns: NhrDocumentSearchResult { documents: [] } OR throws\n \nuseSearchDocuments() hook (line 33)\n ↓ Wraps via queryClient.fetchQuery + maps to { data, total }\n ↓ Returns: SearchDocumentsResult { data: NhrDocument[], total: number }\n \nuseDmpDocumentListVariant()\n ↓ Passes searchDocuments as prop\n ↓ Returns: NhrDocumentListVariant { searchDocuments, columns, filters }\n \nuseNhrDocumentListVariant()\n ↓ Wraps in product line variation\n ↓ Returns: NhrDocumentListVariant | null\n \nPatientCard.tsx (line 60)\n ↓ Receives nhrVariant with searchDocuments function\n ↓ Passes to NhrEntryPointModule (line 131)\n \nNhrDocumentListModal.tsx (line 46)\n ↓ Calls: const { data, total } = await searchDocuments(appliedFilters)\n ↓ Sets state with data/total (line 47)\n\nThe critical redesign point is that currently useSearchDocuments swallows the error from nhrOperations.searchDocuments() via the retry logic (line 53-56) and only lets it propagate if retry limit is exceeded. To return errors as data, you must:\n\n1. Extend all SearchResult types to include error/status fields\n2. Catch in useSearchDocuments (line 46-49) and map exceptions to the result type\n3.
