Here is the complete review:\n\n---\n\nArchitecture Review: fhir-2213_dmp-api-typed-error-model\n\nSummary of Changes\n\nThe PR adds typed DMP API error handling by introducing DmpApiError (an Error subclass), DmpApiErrorInfo (an interface), extends SearchResult with an optional error field, adds four missing fields to DmpResponse, and updates toSearchResult() to populate the new field.\n\n---\n\nCritical Issues (must fix)\n\n1. DmpApiError class placed in the wrong directory\n\n/Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/business/DmpApiError.ts is placed in src/business/. However, src/business/ in the UpFront convention is reserved for pure business logic and domain types — not for Error subclasses whose primary role is to serve as a transportable value across layer boundaries. More concretely, DmpApiError is not consumed anywhere in src/business/ in this PR; it is only exported from src/index.ts as a public API type for callers outside the package. Its natural home is src/api/, alongside DmpAuthError in auth-types.ts, which is the file explicitly cited by the PR as the pattern being followed.\n\nDmpAuthError lives in /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/api/auth-types.ts — an api/ layer file, not business/. Placing DmpApiError in business/ while its counterpart DmpAuthError lives in api/ creates an inconsistency in the very pattern this PR claims to follow.\n\nRecommended fix: Move DmpApiError.ts and DmpApiError.test.ts to src/api/, and update the import in DmpApiError.ts accordingly (from '../types/DmpApi' to '../types/DmpApi' which doesn't change, but the file itself moves). The src/index.ts export path would change from './business/DmpApiError' to './api/DmpApiError'.\n\n2. DmpApiErrorInfo interface placed in src/types/DmpApi.ts instead of alongside the class it describes\n\nDmpApiErrorInfo is a data-shape interface that exclusively describes the constructor input of DmpApiError. When a type exists solely to type a class that lives in src/api/, it should either live in the same file as that class or in a src/api/ types file — not in src/types/DmpApi.ts, which is the public API contract interface file for DmpApi (the DmpApiImpl). Putting error metadata there conflates two different concerns: the API contract for the search() method and the constructor signature of an error class.\n\nAdditionally, src/types/DmpApi.ts already exports DmpApiErrorInfo transitively via SearchResult.error?: DmpApiErrorInfo. Having DmpApiErrorInfo in DmpApi.ts with a direct export type { DmpApiErrorInfo } in index.ts is fine from a surfacing standpoint, but the location signals that this type belongs to the API method contract, when it actually belongs to the error class.\n\nRecommended fix: Either co-locate DmpApiErrorInfo in the same file as DmpApiError (in src/api/), or move it to src/api/auth-types.ts alongside DmpAuthError and DmpAuthErrorCode. The SearchResult.error field can then import it from '../api/...'.\n\n---\n\nWarnings (should fix)\n\n3. Message construction bug when apiErrorDescription is undefined but apiErrorExtendedInformations is present\n\nIn /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/business/DmpApiError.ts at lines 19–21:\n\nconst message = info.apiErrorExtendedInformations\n  ? ${info.apiErrorDescription}: ${info.apiErrorExtendedInformations}\n  : info.apiErrorDescription ?? 'DMP API error'\n\nIf apiErrorExtendedInformations is present but apiErrorDescription is undefined, the message becomes \"undefined: Operation timed out.\". The extended informations check should be guarded on both fields being present:\n\nconst message =\n  info.apiErrorDescription && info.apiErrorExtendedInformations\n    ? ${info.apiErrorDescription}: ${info.apiErrorExtendedInformations}\n    : info.apiErrorDescription ?? info.apiErrorExtendedInformations ?? 'DMP API error'\n\nThere is no test case covering this scenario (apiErrorExtendedInformations set, apiErrorDescription absent), which allowed the bug to go undetected.\n\n4. status field typed as string instead of a union or literal type\n\nIn DmpApiErrorInfo and correspondingly on DmpApiError, status is typed as string. The existing codebase uses STATUS_OK ('OK') as the only documented success value; the error path currently hard-codes 'ERROR' as fallback. Using bare string loses all static exhaustiveness checking. The downstream FrDmpTypes.ts already models s_status?: string (inherently loose from the transport layer), but the mapped domain type DmpApiErrorInfo is an ideal place to tighten this:\n\nexport type DmpApiStatus = 'OK' | 'ERROR' | string  // or a narrower union if all values are known\n\nAt minimum, consider 'ERROR' | (string & {}) to keep open extensibility while signaling intent. If the full set of non-OK statuses from the DmpConnect-JS2 API is known, an exhaustive union should be used.\n\n5. FindDocumentsResponse not extended with the four new fields — DmpResponse was extended instead\n\nThe four new fields (s_apiErrorContext, s_apiErrorDescription, s_apiErrorExtendedInformations, s_apiErrorTypeDescription) were added to DmpResponse in FrDmpTypes.ts. This is technically correct since FindDocumentsResponse extends DmpResponse, but it means every response type that extends DmpResponse now implicitly declares these fields — including CpxStatusResponse, SessionStateResponse, PcscReadersResponse, etc. — even though error context fields are only consumed for findDocuments responses.\n\nIf these fields are genuinely part of the DmpConnect-JS2 base response protocol for all commands, the placement in DmpResponse is correct and no change is needed. But the PR description says \"add DmpApiError class and propagate DMP error fields through SearchResult\" — if these fields are specific to findDocuments, they belong on FindDocumentsResponse directly. This warrants a clarifying comment on DmpResponse if the intent is that all commands can return these error fields.\n\n6. Export ordering inconsistency in src/index.ts\n\nIn /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/dmp/src/index.ts, DmpApiError and DmpApiErrorInfo are placed at the very top of the file (lines 1–2), before all other exports. The existing export structure groups by concern: business types, events, hooks, components, API auth. The new exports would naturally belong in the // DMP Authentication API section (lines 78–80) alongside DmpAuthError, or in a new dedicated // DMP API Errors section adjacent to it. Placing them at the top of the file without a comment suggests they are the primary exports of the package, which they are not.\n\n---\n\nSuggestions (consider improving)\n\n7. DmpApiError properties duplicate DmpApiErrorInfo fields verbatim\n\nDmpApiError re-declares all seven fields from DmpApiErrorInfo as class properties. Consider storing the original info object directly and delegating property access, or using Object.assign — this reduces duplication when the interface evolves. That said, the explicit readonly declarations do make the public surface of the class self-documenting, so this is a style tradeoff, not a correctness issue.\n\n8. The toSearchResult() error block does not use DmpApiError — consider whether this is intentional\n\ntoSearchResult() constructs a plain DmpApiErrorInfo object literal and attaches it to SearchResult.error. DmpApiError itself is never constructed inside the package. This means the class is only useful to callers who want to re-throw — it's a utility class, not an internal mechanism. That is a valid design, but it should be documented: a JSDoc comment on DmpApiError explaining that callers should construct it from SearchResult.error \n…(truncated, 606 more chars)",
