Tool results:

→ result (ok): The local worktree is in a detached HEAD state that doesn't match the PR branch. The actual PR branch FHIR-2224-monolith-return-doc-status-update-results-from-dmp-api isn't checked out locally. The PR diff is the ground truth. Let me verify what the PR diff actually introduces vs what we can test against — especially the type divergence (PR uses { success: true/false } discriminated union, while local code uses { error?: DmpApiErrorInfo }).

Tool results:

→ result (ok): Good. The DmpApiError constructs the message from DmpApiErrorInfo correctly with fallback to 'DMP API error'. The adapter's use of new DmpApiError(result.error).message is sound.

Now I have enough context. Let me also verify the dmpService path test for BusinessError. Looking at the diff:

★ Insight ───────────────────────────────────── This PR introduces the "error-as-value" pattern (returning structured results instead of throwing). The tension the agents found — discriminated union vs optional-error — is a classic API design dilemma: discriminated unions force callers to narrow the type before accessing error fields (compile-time safety), while optional-error shapes mirror what's already established in the codebase. The real risk here is mixing both in the same package without a clear migration story. ─────────────────────────────────────────────────

Here are the review comments from all five agents:

packages/@doctolib/dmp/src/types/DmpApi.ts

📁 packages/@doctolib/dmp/src/types/DmpApi.ts : line 186 issue (blocking): Type shape conflicts with the SearchResult pattern established in the same file

The PR description claims this mirrors SearchResult ({ documents, error?: DmpApiErrorInfo }), but the diff introduces a discriminated union { success: true } | { success: false; error: DmpApiErrorInfo } — a fundamentally different contract. Using two different result patterns for sibling operations in the same package (search vs updateDocumentStatus) creates inconsistency that will confuse future callers. Additionally, the implementation in DmpApi.ts still returns {} on success, not { success: true }, so the type and the runtime shape don't match. Pick one pattern and apply it consistently: either keep interface DocumentStatusUpdateResult { error?: DmpApiErrorInfo } (lighter, matches SearchResult), or update SearchResult to a discriminated union too.

📁 packages/@doctolib/dmp/src/types/DmpApi.ts : line 192 issue (blocking): healthCareSettings field still required in props type, but adapter no longer passes it

The diff removes healthCareSettings from the updateDocumentStatus call in DmpNhrAdapter, but DocumentStatusUpdateProps still declares healthCareSettings: string as required. This means the adapter will fail TypeScript compilation. Either keep the field and have the adapter continue passing it, or make it optional (healthCareSettings?: string) and update the implementation to read it from frDmpWorkflow internally.

📁 packages/@doctolib/dmp/src/types/DmpApi.ts : line 171 suggestion (non-blocking): DmpApiErrorInfo.status typed as string but used as a discriminant

The status field drives the error display logic downstream but is string. A 'OK' | 'ERROR' | (string & {}) or a named literal union would make the intent explicit and prevent the ?? 'ERROR' fallback in the implementation from being the only guard against undefined.

packages/@doctolib/dmp/src/business/DmpApi.ts

📁 packages/@doctolib/dmp/src/business/DmpApi.ts : line 361 issue (blocking): catch(e) on the dmpService path swallows all errors — contradicts the PR description

The PR description states "Non-BusinessError still propagates." The implementation at line 361 catches e instanceof Error generically and converts every thrown value to a structured result, including network errors, programming bugs (TypeError, ReferenceError), and timeout errors. This silently hides infrastructure failures from callers and error monitoring. Fix:

} catch (e) {
  if (e instanceof BusinessError) {
    return { success: false, error: { status: 'ERROR', apiErrorDescription: e.message } }
  }
  throw e
}

📁 packages/@doctolib/dmp/src/business/DmpApi.ts : line 390 issue (blocking): Same over-broad catch on the legacy (iCanopée) path

The new try/catch added around updateDocumentStatusCommand also swallows all exceptions, including transport failures. This is a second silent failure mode. Narrow it the same way as the dmpService path, or — if you want the legacy path to be fully error-as-value — explicitly state that in the PR and add tests covering transport errors.

📁 packages/@doctolib/dmp/src/business/DmpApi.ts : line 348 issue (blocking): frDmpWorkflow guard still throws — breaks the new no-throw contract

if (!this.props.frDmpWorkflow) throw new Error('frDmpWorkflow is required...') throws unconditionally, but the adapter (DmpNhrAdapter) has removed its surrounding try/catch in this PR. A missing frDmpWorkflow at runtime will now produce an unhandled rejection rather than an error payload. Either convert this guard to return a structured error, or keep it as-is and restore the adapter's try/catch for this case.

📁 packages/@doctolib/dmp/src/business/DmpApi.ts : line 386 suggestion (non-blocking): 7-field iCanopée response mapping duplicates the one in search()

The { status, apiErrorCode, apiErrorType, ... } mapping from s_status/i_apiError* fields is identical to the one already written for search() around line 587. Extract a small helper toDmpApiErrorInfo(response) and reuse in both places. This eliminates a future drift risk if the iCanopée field names ever change.

📁 packages/@doctolib/dmp/src/business/DmpApi.ts : line 363 suggestion (non-blocking): Two identical catch bodies — extract shared helper

The dmpService and legacy paths both produce:

const message = e instanceof Error ? e.message : 'Unknown error'
return { success: false, error: { status: 'ERROR', apiErrorDescription: message } }

A one-liner toUnknownErrorResult(e: unknown): DocumentStatusUpdateResult removes duplication. Also check whether 'Unknown error' should use the DmpApiError fallback string 'DMP API error' for consistency with the rest of the package.

📁 packages/@doctolib/dmp/src/business/DmpApi.ts : line 102 chore (non-blocking): DocumentStatusUpdateResult re-exported from the implementation file

src/index.ts already exports DocumentStatusUpdateResult directly from ./types/DmpApi. The additional re-export from src/business/DmpApi.ts (lines 115–117) is redundant and blurs the type-vs-implementation boundary. Remove it.

packages/@doctolib/dmp/src/business/DmpApi.test.ts

📁 packages/@doctolib/dmp/src/business/DmpApi.test.ts : line ~2047 issue (blocking): Test "should return error result when dmpService throws an unexpected error" asserts behavior that doesn't exist

If the implementation correctly narrows to only catch BusinessError (as it should per the PR description), then throwing new Error('Network failure') should propagate, not return a structured result. This test documents — and therefore locks in — the over-broad catch. If the catch is fixed (see DmpApi.ts:361 above), this test will need to become rejects.toThrow('Network failure') instead.

📁 packages/@doctolib/dmp/src/business/DmpApi.test.ts : line ~1627 issue (blocking): "should return error result when no DMP session found" contradicts the throwing guard

The frDmpWorkflow-missing path still throws. Unless that guard is converted to return a structured result (see DmpApi.ts:348), the test expectation { success: false, error: { ... } } will fail.

📁 packages/@doctolib/dmp/src/business/DmpApi.test.ts : line ~1590 suggestion (non-blocking): Extract a shared updateProps constant

The same { ins: '123456789012345678901', documentUniqueId: 'unique-doc-123', uuid: 'uuid-doc-456' } literal is repeated across every it block in both the legacy and dmpService describe blocks. A const updateProps = { ... } at describe scope removes ~10 lines of duplication and focuses each test on what's unique.

📁 packages/@doctolib/dmp/src/business/DmpApi.test.ts : line ~1638 nitpick (non-blocking): expect.objectContaining is redundant where the full shape is known

expect.objectContaining({ status: 'ERROR', apiErrorDescription: '...' }) on a literal that only ever has those two fields provides no benefit over a plain toEqual on the complete object. Reserve objectContaining for the iCanopée path where extra response fields may vary; drop it on the `'E …(truncated, 5387 more chars)

Your status line is now configured. It will display in this format:

Segments shown: - Model — current Claude model - Folder — workspace directory name - Git branch — detected from the active branch (worktree-aware) - Context usage — hidden until after the first API call, then shows percentage

The script lives at ~/.claude/statusline.sh. If you want to tweak the format (add rate limits, vim mode indicator, etc.), just ask and I'll delegate back to the statusline agent.
