You are a Senior Frontend Software Engineer at Doctolib and you have to plan the implementation to make the pagination of the NhrDocumentList which now is on client side, to server side. You have to follow the Doctolib development guidelines and use a TDD aproach to implement the feature

Context: - In the treatment-plan project, inside the package tpf-national-health-records-ui, the pagination logic is implemented inside the component NhrDocumentListTable.tsx. However, the idea is that pagination must be a filter parameter to be parsed and used as query parameters for an api call through searchDocuments function. - The searchDocuments function is passed as a callback from the NhrEntryPoint.tsx, implemented in treatment-plan project, inside the package tpf-national-health-records-ui, but mounted on monolith by the packages/@doctolib/shared_patient_file_and_appointment_page_components/src/desktop/PatientCard/PatientCard.tsx:117 and receiving the real function implementation from the useNhrDocumentListVariant. - useNhrDocumentListVariant receives the implementation of the searchDocuments function from the hook on monolith packages/@doctolib/national-health-records/src/hooks/useSearchDocuments.ts. Here the response should return with the pagination in place, and with an additional data to the response containing the current page.

Repositories: - monolith project: @/Users/USER/workspace/doctolib/doctolib/ - monolith specific package for national-health-records: @/Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records - treatment-plan project: @/Users/USER/workspace/doctolib/treatment-plan/ - @doctolib/tpf-national-health-records-ui: @/Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records-ui - @doctolib/tpf-national-health-records: @/Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records

Expected output: - A comprehensive plan on markdown format described in details on @/Users/USER/Library/CloudStorage/<REDACTED>/My Drive/ai-artifacts/nhr-document-list/pagination/server-side-pagination-plan.md, with justification why the plan will work. Suggest mock changes if necessary.

The directory exists and is empty. Now let me write the comprehensive plan.

★ Insight ───────────────────────────────────── Before diving in, three architectural observations that shape this plan:

1. The callback-coupling pattern: SearchDocumentsFn currently has no pagination contract in its signature. The page number lives in the UI's local state and never crosses the component boundary down to the actual API call. Adding it to the function signature is the critical seam.
2. React Query's cache key is the pagination lever: The existing queryKey: ['dmp-documents', ins, appliedFilters] in useSearchDocuments will naturally bust the cache when page is added to appliedFilters — no new cache management is needed.
3. The NhrDocumentSearchResult type in tpf-national-health-records has no pagination fields ({ documents: NhrDocument[] }), meaning the DMP backend API response itself doesn't paginate yet. Server-side pagination must either be added to the API layer or emulated in the adapter. ─────────────────────────────────────────────────

★ Insight ───────────────────────────────────── Three architectural decisions worth understanding from the plan:

1. page in the React Query cache key vs. merged into appliedFilters: Keeping them separate (queryKey: ['dmp-documents', ins, appliedFilters, page]) means filter changes don't invalidate page-specific cache entries and vice versa. If you merged them, changing the page would also force re-evaluation of all filter-cache entries.

2. requestedPage vs. currentPage split in the modal: requestedPage drives the fetch (what we asked for), currentPage reflects what the server confirmed (what we got). This prevents the pagination UI jumping ahead before the new page's data arrives — a subtle but important UX detail.

3. The adapter as the Scenario A/B isolation boundary: Whether the DMP API supports native pagination today or not, the DmpNhrAdapter is the single file that changes when it does. The entire UI layer above — the hooks, the components, the types — is identical in both scenarios. This is the anti-corruption layer pattern working correctly. ─────────────────────────────────────────────────

The plan has been written to:

~/GoogleDrive/ai-artifacts/nhr-document-list/pagination/server-side-pagination-plan.md

Here's a summary of what the plan covers:

Architecture: The core insight is that currentPage must cross the SearchDocumentsFn boundary as a parameter — it currently lives in local React state and never reaches useSearchDocuments or the DMP adapter.

11 implementation steps in TDD order: 1. Extend NhrDocumentSearchParams (add pagination) and NhrDocumentSearchResult (add totalCount) in tpf-national-health-records 2. Update DmpNhrAdapter to map pagination to/from the DMP API 3. Add page param and currentPage to SearchDocumentsResult in monolith types 4. Update useSearchDocuments to include page in the React Query cache key 5. Update mapFiltersToSearchDocumentsParams to extract page/pageSize → pagination 6. Extend SearchDocumentsFn type in the UI package 7. Move page state to NhrDocumentListModal (it owns fetch lifecycle) 8. Make NhrDocumentList a controlled component for pagination 9. Delete getPagedData (dead code once server handles slicing) 10. Fix now-invalid client-side pagination tests 11. Update the mock generator for the feature flag path

The plan also includes a feature switch strategy (nhr_document_list_server_side_pagination) for safe gradual rollout, a Scenario A/B analysis for whether the DMP API supports native pagination, and a risk matrix with mitigations.

the DmpNhrAdapter must not change, the pagination must be done on useSearchDocuments/mapFiltersToSearchDocumentsParams layer

Turn 2 — Assistant

Good correction. The adapter is infrastructure-layer; pagination is a concern of the application layer. Let me update the plan to reflect this.

Done. The plan is updated with two changes:

1. DmpNhrAdapter removed from scope — Step 2 (adapter changes) is gone. The adapter is never touched. Slicing happens entirely in useSearchDocuments after the React Query cache lookup.

2. Feature switch removed — The change ships as a direct cut-over. The type signature changes are backward-compatible (optional params/fields), so no dual-mode branching is needed. getPagedData is deleted immediately rather than kept behind a flag.

The revised scope is lean: 8 focused steps across the monolith hook layer and the two treatment-plan packages, with no infrastructure changes and no feature flag ceremony.
