The PR is checked out at /Users/USER/workspace/doctolib/worktrees/doctolib/FHIR-2224/.\n\nChanged files to analyze:\n1. packages/@doctolib/dmp/src/business/DmpApi.ts — specifically the updateDocumentStatus method (~lines 346–400)\n2. packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts — specifically updateDocumentMetadata (~lines 206–262)\n3. packages/@doctolib/dmp/src/types/DmpApi.ts — DocumentStatusUpdateResult interface (lines ~186–188)\n\nSimplification angles to explore:\n\n1. DmpNhrAdapter.ts line ~234: new DmpApiError(result.error).message — instantiating a full class object just to call .message. Would a standalone getDmpApiErrorMessage(info: DmpApiErrorInfo): string helper function be simpler? Or is the full object instantiation intentional for consistency?\n\n2. DmpApiImpl.updateDocumentStatus legacy path (~lines 385–398): The error object spread has 6 optional fields all mapped from response.. Could this be extracted into a helper like toDmpApiErrorInfo(response) to reduce repetition, especially since similar mapping likely exists elsewhere in the codebase?\n\n3. DocumentStatusUpdateResult is structurally identical to SearchResult minus documents: Could it simply reuse Omit<SearchResult, 'documents'> or should it remain independent?\n\n4. The cast removal: } as DocumentStatusUpdateProps) was removed. Can the caller infer the type correctly now, or is it implicit? Is the type inference now explicit enough?\n\n5. s_status ?? 'ERROR' in DmpApi.ts line ~394: This is unreachable — if s_status !== STATUS_OK is true and s_status is nullish, we'd never get here since the check already ran. Should the fallback be removed or documented?\n\nRead the actual files and suggest simplifications that are safe and don't change behavior. Report in Conventional Comments format with file:line references.\n\nTurn 1 — Assistant\n\nI'll analyze the recently modified code in PR #241133 for simplification opportunities.

Here is my review.\n\n---\n\nCode Review — PR #241133 (FHIR-2224)\n\nReviewed files\n- /Users/USER/workspace/doctolib/worktrees/doctolib/FHIR-2224/packages/@doctolib/dmp/src/business/DmpApi.ts\n- /Users/USER/workspace/doctolib/worktrees/doctolib/FHIR-2224/packages/@doctolib/national-health-records/src/business/adapters/DmpNhrAdapter.ts\n- /Users/USER/workspace/doctolib/worktrees/doctolib/FHIR-2224/packages/@doctolib/dmp/src/types/DmpApi.ts\n- /Users/USER/workspace/doctolib/worktrees/doctolib/FHIR-2224/packages/@doctolib/dmp/src/api/DmpApiError.ts (referenced)\n\n---\n\nComment 1 — DmpNhrAdapter.ts:234 — new DmpApiError(result.error).message\n\nsuggestion (non-blocking):\nInstantiating a full Error subclass purely to read .message is mildly wasteful and obscures intent — readers wonder \"is this thrown? caught? logged?\" when it is none of those. Extract a tiny standalone helper colocated with DmpApiError:\n\n// packages/@doctolib/dmp/src/api/DmpApiError.ts\nexport function getDmpApiErrorMessage(info: DmpApiErrorInfo): string {\n  if (info.apiErrorDescription && info.apiErrorExtendedInformations) {\n    return ${info.apiErrorDescription}: ${info.apiErrorExtendedInformations}\n  }\n  return info.apiErrorDescription ?? info.apiErrorExtendedInformations ?? 'DMP API error'\n}\n\nexport class DmpApiError extends Error {\n  // ...\n  constructor(info: DmpApiErrorInfo) {\n    super(getDmpApiErrorMessage(info))\n    // ...\n  }\n}\n\nThen at DmpNhrAdapter.ts:234:\nmessage: getDmpApiErrorMessage(result.error),\n\nBenefits: removes the indirection through Error allocation/stack capture, makes the call self-describing, single source of truth for the message format (the class still uses the same helper). Also lets the test mock at DmpNhrAdapter.test.ts:24-33 shrink — it currently re-implements the message logic inline.\n\nCaveat: if a future refactor will throw the full DmpApiError here (i.e. the class shape is already the target API for the adapter), keep the instantiation — that future change matters more than the small allocation. Decide based on intent.\n\n---\n\nComment 2 — DmpApi.ts:385-397 and DmpApi.ts:582-593 — duplicated response→error mapping\n\nissue (blocking-ish for elegance):\nThe block at lines 385-397 is byte-identical to the one at lines 585-591 inside toSearchResult. Both translate DmpResponse (camelCase s_ / i_) to DmpApiErrorInfo. This is the strongest simplification opportunity in the diff.\n\nsuggestion:\nExtract a private helper colocated with the class (or as a free function in this module since it has no this):\n\nfunction toDmpApiErrorInfo(response: DmpResponse): DmpApiErrorInfo {\n  return {\n    apiErrorCode: response.i_apiErrorCode,\n    apiErrorType: response.i_apiErrorType,\n    apiErrorContext: response.s_apiErrorContext,\n    apiErrorDescription: response.s_apiErrorDescription,\n    apiErrorExtendedInformations: response.s_apiErrorExtendedInformations,\n    apiErrorTypeDescription: response.s_apiErrorTypeDescription,\n    status: response.s_status ?? 'ERROR',\n  }\n}\n\nThen:\n\n// DmpApi.ts:385\nif (response.s_status !== STATUS_OK) {\n  return { error: toDmpApiErrorInfo(response) }\n}\nreturn {}\n\n// DmpApi.ts:582\nerror: response.s_status !== STATUS_OK ? toDmpApiErrorInfo(response) : undefined,\n\nThis shrinks two 7-line blocks to one and creates a single point of truth that future fields (e.g. s_apiErrorDmpErrorCode, already used at line 811) can be added to.\n\n---\n\nComment 3 — DmpApi.ts:394 — \"unreachable\" s_status ?? 'ERROR'\n\nnitpick (correction):\nThe prompt's claim that this fallback is unreachable is incorrect. s_status is typed string | undefined on DmpResponse (FrDmpTypes.ts:194), and STATUS_OK = 'OK'. The guard response.s_status !== STATUS_OK evaluates to true for both 'ERROR' and undefined, so the inner branch can run with s_status === undefined. The ?? 'ERROR' is correctly defending against that case.\n\nIf extracted into toDmpApiErrorInfo (Comment 2), the fallback lives in exactly one place and the question stops coming up. No code change needed beyond Comment 2.\n\n---\n\nComment 4 — types/DmpApi.ts:181-188 — DocumentStatusUpdateResult shape\n\nnitpick:\nYou raised the option DocumentStatusUpdateResult = Omit<SearchResult, 'documents'>. I'd recommend leaving it as a standalone interface:\n\n- The two types are semantically distinct (one is the result of a query that happens to share an error envelope; the other is the result of a mutation). Coupling them via Omit would mean any future SearchResult-only field (e.g. pagination cursor, totalCount) would have to be threaded through Omit.\n- Omit<SearchResult, 'documents'> is also less readable in IDE hovers than the explicit { error?: DmpApiErrorInfo }.\n- Each interface is two lines — there is no real duplication cost.\n\nA lighter alternative if the duplication does start to bite: define a base type and extend, e.g.\n\ninterface DmpApiErrorEnvelope { error?: DmpApiErrorInfo }\nexport interface SearchResult extends DmpApiErrorEnvelope { documents: DmpDocument[] }\nexport type DocumentStatusUpdateResult = DmpApiErrorEnvelope\n\nBut I would only do this once a third call site appears.\n\n---\n\nComment 5 — Cast removal at the call site (referenced in PR description)\n\npraise:\nRemoving as DocumentStatusUpdateProps at the call site (DmpNhrAdapter.ts:221-226) is a clean win. The literal object passed to updateDocumentStatus now relies on TypeScript contextual typing from the parameter type at DmpApi.ts:346, which is exactly the right pattern. Casts only mask type errors; contextual typing surfaces them. Keep it as-is.\n\n---\n\nComment 6 — DmpNhrAdapter.ts:206-262 — overall structure of updateDocumentMetadata\n\nnitpick (optional):\nThe async payloads.map callback is ~40 lines with three exit branches (success, error from result, skipped) plus a try/catch. Consider extracting the per-payload work to a private method processMetadataUpdate(payload, ins, healthcareSettings): Promise<NhrDocumentMetadataUpdatePayloadResult>. This:\n\n- shrinks updateDocumentMetadata to its true responsibility (validation, fan-out, fold);\n- makes future support for propertyName === 'visibility' a one-line edit instead of further nesting (the current TODO at line 241 hints at this);\n- makes each branch independently testable.\n\nSkeleton:\n\nasync updateDocumentMetadata(props: NhrDocumentMetadataUpdateProps): Promise<NhrDocumentMetadataUpdateResult> {\n  if (!props.patient?.nationalHealthIdentifier) {\n    throw new Error('patient_national_health_identifier_required')\n  }\n\n  const ins = toEnvIns(props.patient.nationalHealthIdentifier)\n  const { healthcareSettings } = props.additionalInfo\n\n  const payloadResults = await Promise.all(\n    props.params.payloads.map((payload) => this.processMetadataUpdate(payload, ins, healthcareSettings))\n  )\n\n  return this.buildUpdateResult(payloadResults)\n}\n\nFunctionality is unchanged.\n\n---\n\nSummary\n\n| # | File:line | Severity | Change |\n|---|---|---|---|\n| 1 | DmpNhrAdapter.ts:234 | suggestion | Optional: getDmpApiErrorMessage helper |\n| 2 | DmpApi.ts:385-397 & :582-593 | suggestion (recommended) | Extract toDmpApiErrorInfo(response) — eliminates real duplication |\n| 3 | DmpApi.ts:394 | nitpick | Fallback is correctly reachable; no code change |\n| 4 | types/DmpApi.ts:186-188 | nitpick | Keep as standalone interface |\n| 5 | call site cast removal | praise | Already correct |\n| 6 | DmpNhrAdapter.ts:206-262 | nitpick | Optional method extraction for future visibility support |\n\nThe single highest-value change is Comment 2 (extract toDmpApiErrorInfo`).
