I need to understand two things:

1. useProductLineVariation — can it return objects/configs, not just components? - Read packages/@doctolib/variation_management/src/ — specifically useProductLineVariation — to understand if it can return arbitrary objects (column configs, filter definitions, data hooks) rather than just React components - Look for examples in the codebase where useProductLineVariation returns something other than a component (an object, a function, a boolean, a config array) - Read packages/@doctolib/clinical_contact_list/src/hooks/useIsCareTeamEnabled.ts as a reference for returning booleans - Search for any variation that returns an object/array/hook (not just a component or boolean)

2. @doctolib/dmp/src/ full structure - Run find /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src -type f | sort to get the complete file tree - Read the full src/index.ts to see what's exported - Read src/helpers/FrDmpHelpers.ts to understand the existing helper patterns - Check if there's a types/ or models/ folder with document-related types (NhrDocument, etc.)

3. NhrDocument type location - Where does NhrDocument type come from? Search in treatment-plan/packages/tpf-national-health-records/src/ for the NhrDocument type definition - Does tpf-national-health-records export a NhrService interface/class? Read its src/index.ts

Search paths: - /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/ - /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/variation_management/src/ - /Users/USER/workspace/doctolib/treatment-plan/packages/tpf-national-health-records/src/

Excellent! Now I have all the information needed. Let me compile a comprehensive summary:

Summary Report

I've completed a thorough exploration of the three areas you requested. Here are my findings:

1. useProductLineVariation — Can It Return Objects/Configs, Not Just Components?

SHORT ANSWER: YES — Absolutely. useProductLineVariation is a generic, type-safe hook that can return ANY type of value, not just React components.

Key Evidence

From /packages/@doctolib/variation_management/src/product-line/useProductLineVariation.ts:

function useProductLineVariation<VariantType, T extends ProductLineVariationType = 'key'>({
  variants,
  type,
  isComponent,
}: {
  variants: Record<ProductLineVariationTypeMap[T], VariantType | null>
  type?: T
  isComponent?: true
}): VariantType

function useProductLineVariation<VariantType, T extends ProductLineVariationType>({
  variants,
  type = 'key' as T,
  isComponent = false,
}: {
  variants: Record<ProductLineVariationTypeMap[T], VariantType>
  type?: T
  isComponent?: boolean
}): VariantType {
  // ...returns variant
}

The hook uses generic VariantType — it returns whatever type you put in the variants object.

Real-World Examples in Codebase

1. Returns Objects/Configs: - useTemplateEditorConfiguration.ts returns TemplateEditorConfiguration (object with allowedTemplateKinds, variablesEnabled, availableVariables) - useInProgressPrescriptionsVariant.ts returns InProgressPrescriptionsContextType (context object)

2. Returns Functions: - useMedicationRequestAdapterVariant.ts returns a function type: (medicationRequest: TimelineItemMedicationRequest) => TimelineItemPrescription | TimelineItemMedicationRequest

3. Returns Booleans: - useIsCareTeamEnabled.ts returns boolean per product line

Example from codebase:

// From useTemplateEditorConfiguration.ts
return useProductLineVariation({
  type: 'key',
  variants: {
    [ProductLineKey.EhrFranceDefault]: {
      allowedTemplateKinds: FR_EHR_CONSULTATION_DOCUMENT_TEMPLATE_ALLOWED,
      variablesEnabled: true,
      availableVariables: frTemplateVariablesWhitelist,
    },
    // ... more variants
  },
})

3. NhrDocument Type Location & NhrService

NhrDocument Type

Location: /treatment-plan/packages/tpf-national-health-records/src/business/types/document.ts

Type Definition:

export type NhrDocument = {
  id: string
  title: string
  description?: string
  identifiers: Record<string, string>
  creationDate: string
  submissionDate?: string
  serviceInformation: ServiceInformation
  status: string
  visibility: string
  format: string
  authors: Author[]
  classification: DocumentClassification
}

NhrService Interface

Location: /treatment-plan/packages/tpf-national-health-records/src/business/types/service.ts

Type Definition:

export type NhrService = {
  searchDocuments(props: DocumentSearchProps): DocumentSearchResult
}

export type DocumentSearchResult = {
  documents: NhrDocument[]
}

Factory Function

Location: nhr-service-factory.ts

export const createNhrService = (countryCode: CountryCode, nhrAdapter: NhrAdapter) => {
  switch (countryCode) {
    case 'fr':
      return new DmpNhrService(nhrAdapter)
    default:
      throw new Error(`Unsupported country code: ${countryCode}`)
  }
}

DMP Service Implementation

Location: dmp-nhr-service.ts

export class DmpNhrService implements NhrService {
  readonly country = 'fr'
  constructor(readonly nhrAdapter: NhrAdapter) {}
  searchDocuments(props: DocumentSearchProps): DocumentSearchResult {
    return this.nhrAdapter.searchDocuments(props)
  }
}

DMP Types (Rich Metadata)

Location: /treatment-plan/packages/tpf-national-health-records/src/business/systems/dmp/types/types.ts

Contains highly detailed iCanopee JSON v2.1.0 structures: - DmpDocument — Raw document structure with 15+ fields (uniqueId, title, classCode, typeCode, creationDate, authors, etc.) - Author — Healthcare professional with profession, specialty, authentication mode - DmpListParams — Search parameters (categories, formats, practices, date ranges, status, visibility) - Address & Telecom — Contact info structures

Module Exports

Location: index.ts

export { createNhrService } from '#business/nhr-service-factory'
export type { NhrAdapter, NhrService } from '#business/types/service'
// NhrDocument imported from document.ts

Key Insights for Your Work

1. Variation management is powerful & flexible — Use it for more than just component selection. Perfect for config objects, adapters, hooks, and feature-dependent behavior.

2. DMP package is well-structured — Clear separation: business logic, API types, helpers, hooks, components. Easy to extend.

3. NhrDocument is a lightweight wrapper — Built on top of more detailed DmpDocument from iCanopee API. The NhrService adapter pattern allows country-specific implementations.

4. Type safety throughout — All three packages use strong TypeScript generics and discriminated types. Perfect foundation for adding new variations/product lines.
