Here is the full structured analysis.\n\n---\n\nType Design Review: PR #241133 — feat(FHIR-2224): return doc status update results from DmpApi\n\nAll file paths refer to the PR branch (FHIR-2224-monolith-return-doc-status-update-results-from-dmp-api).\n\n---\n\nType: DocumentStatusUpdateResult\n\nFile: packages/@doctolib/dmp/src/types/DmpApi.ts, line 186\n\nDefinition:\nexport type DocumentStatusUpdateResult = { success: true } | { success: false; error: DmpApiErrorInfo }\n\nInvariants Identified\n- A result is either a success with no error payload, or a failure with a mandatory DmpApiErrorInfo.\n- There is no representable state where success: true and an error co-exist.\n- There is no representable state where success: false exists without a concrete error.\n\nRatings\n\n- Encapsulation: 8/10\n  The type is exported from the package index and is properly opaque from the caller's perspective. The DmpApiImpl class is the only producer, and callers can only consume via the discriminant. There are no mutable internals. A minor deduction: DmpApiErrorInfo itself has all-optional fields (except status), which means the error payload is structurally weak — but that is a separate, pre-existing concern inherited from the DMP API response shape.\n\n- Invariant Expression: 9/10\n  The discriminated union on the success boolean literal makes it a genuine tagged union. TypeScript narrows the type correctly when callers branch on result.success. Accessing result.error without first checking result.success === false is a compile-time error. This is the strongest possible expression of this invariant without introducing a nominal wrapper type.\n\n- Invariant Usefulness: 9/10\n  The PR's own motivation is precisely that callers previously had no structured way to inspect DMP-specific error fields — they could only catch a string-messaged Error. The new type enforces at compile time that callers handle the error case and gives them access to apiErrorCode, apiErrorType, apiErrorDescription, and apiErrorExtendedInformations. This directly prevents the class of bug where a caller silently ignores DMP error detail.\n\n- Invariant Enforcement: 8/10\n  The DmpApiImpl implementation always returns one of the two union members — success returns { success: true }, all error paths return { success: false, error: ... }. The interface definition at line 112 ensures no conforming implementation can return void or throw as the primary signal. One gap: on the dmpService path, only BusinessError is caught and turned into a structured result; non-BusinessError exceptions still propagate as throws. This means callers interacting with DmpApiImpl via the DmpApi interface cannot rely on the no-throw guarantee uniformly across both code paths.\n\nStrengths\n- The discriminated union design is clearly superior to the SearchResult pattern ({ error?: DmpApiErrorInfo }) used elsewhere in the same file. The SearchResult pattern requires callers to test if (result.error) but TypeScript does not enforce the check — a caller can read result.documents and silently ignore result.error. With the discriminated union, the TypeScript compiler forces callers to narrow the type before accessing error fields, so the error path cannot be silently skipped.\n- Removing healthCareSettings from DocumentStatusUpdateProps (line 190–195) is a meaningful cohesion improvement. The implementation now reads healthcareSettings from this.props.frDmpWorkflow, which is the canonical place for that value, eliminating a redundant input that callers could supply inconsistently.\n- The DmpApiError class (at packages/@doctolib/dmp/src/api/DmpApiError.ts) provides a single, tested message-composition rule that correctly combines apiErrorDescription and apiErrorExtendedInformations with a : separator and falls back to 'DMP API error'. By routing through new DmpApiError(result.error).message in DmpNhrAdapter, the PR avoids duplicating that logic.\n\nConcerns\n\n1. Asymmetric throw behaviour between code paths.\n   In DmpApiImpl.updateDocumentStatus, the dmpService path wraps only BusinessError in a structured result and re-throws everything else (line ~363: throw e). The legacy getCachedDmpSession / updateDocumentStatusCommand path wraps everything in a try/catch and never throws (lines ~370–405). A caller who switches between the two paths at runtime (which is the design — the dmpService path is behind a feature switch) gets different exception-vs-result semantics. The DmpApi interface signature alone cannot express this: it says Promise<DocumentStatusUpdateResult> with no indication that non-BusinessError may still reject the promise. This is a latent correctness risk at the adapter layer (DmpNhrAdapter still has a surrounding try/catch at line 249 in the worktree copy, masking the gap for now, but the PR version removes that safety net).\n\n2. DmpApiErrorInfo fields are all optional except status.\n   The error member of the failure branch is typed as DmpApiErrorInfo, in which apiErrorDescription, apiErrorCode, apiErrorType etc. are all string | undefined. This means a fully valid { success: false, error: { status: 'ERROR' } } carries no human-readable message. Callers must defensively handle the undefined case. The DmpApiError class handles this correctly with its fallback to 'DMP API error', but a caller who directly reads result.error.apiErrorDescription without going through DmpApiError will get undefined. This is not a new issue introduced by the PR, but the new type makes it the caller's problem in a more visible way.\n\n3. Divergence from the SearchResult pattern is not documented.\n   The PR description correctly notes that DocumentStatusUpdateResult mirrors SearchResult. In fact it improves on it by using a discriminated union instead of an optional error, but the existing SearchResult interface is left in the older, weaker form. A future developer reading both types in the same file will see two different idioms for the same concept (optional-error vs. discriminated union) without any comment explaining the intentional improvement. This invites regression to the weaker pattern for new result types.\n\n4. The success field carries no additional payload on the success branch.\n   { success: true } is a valid and simple design, but it means callers get no confirmation detail (no response timestamp, no document ID echo, nothing). For search(), SearchResult includes documents. For updateDocumentStatus, success is purely acknowledged by the absence of an error. This is appropriate for an update operation, but worth noting as a deliberate design choice since it means the type cannot be extended to carry success-side data without a breaking change to the union.\n\nRecommended Improvements\n\n1. Make the throw behaviour consistent across both code paths.\n   The cleanest fix is to wrap the entire body of updateDocumentStatus — both the dmpService branch and the legacy branch — in a single top-level try/catch that converts any exception into a { success: false, error: { status: 'ERROR', apiErrorDescription: message } } result. This fulfils the implied promise of the DocumentStatusUpdateResult return type: that the function always resolves to a structured value and never rejects. This would require updating the two tests that currently assert re-throw behaviour on the dmpService path.\n\n2. Annotate the intentional departure from SearchResult.\n   A short comment at the DocumentStatusUpdateResult declaration stating why a discriminated union is used instead of the SearchResult-style optional error would help maintain consistency for future result types added to this interface.\n\n3. Consider tightening DmpApiErrorInfo.apiErrorDescription to string \n…(truncated, 3938 more chars)",
