Review recently modified code in the Doctolib monorepo at /Users/USER/workspace/doctolib/doctolib on branch fhir-2245_observability-search-documents for simplification opportunities. This is the third review pass.

Focus on these 5 files only: 1. packages/@doctolib/national-health-records/src/business/adapters/nhrMonitoring.ts 2. packages/@doctolib/national-health-records/src/business/adapters/NhrAdapterWithObservability.ts 3. packages/@doctolib/national-health-records/src/business/adapters/NhrAdapterWithObservability.test.ts 4. packages/@doctolib/national-health-records/src/business/adapters/nhrMonitoring.test.ts 5. packages/@doctolib/national-health-records/src/hooks/useDmpNhr.ts

Context: The two-phase observe<TAction>(action).execute<TResult>(...) pattern is intentional — it constrains TypeScript inference at each call site via mapped types. The as NhrRequestDetails / as NhrResponseDetails casts inside execute() are necessary because TypeScript cannot narrow through spread on mapped index types. The .catch(() => {}) fire-and-forget pattern is intentional (matches ti_connect convention). Do NOT suggest removing these.

Identify only simplifications that reduce complexity without changing behaviour. Report with file:line or say "no simplifications needed".

I've reviewed all 5 files. Here are the simplification opportunities I found.

Findings

NhrAdapterWithObservability.ts

Lines 41–74: Duplicated infrastructure fields and duration_ms computation across three sendNhrResponse call paths.

The same { trace_id, adapter, action, phase: 'response', duration_ms: ... } is built three times — once in success, once in catch (and once for request). The performance.now() - start is duplicated in success and error paths. A single small helper inside execute would reduce repetition without changing behaviour or types.

Concretely, you could hoist the response-base into a closure:

const sendResponse = (fields: NhrResponseActionFields[TAction]): void => {
  sendNhrResponse({
    trace_id: traceId,
    adapter: this.adapterName,
    action,
    phase: 'response',
    duration_ms: performance.now() - start,
    ...fields,
  } as NhrResponseDetails)
}

Then the success branch becomes sendResponse(buildSuccessFields(result)) and the catch branch becomes sendResponse({ status: 'error', error_message: ... }). This collapses ~12 lines of duplication into a single helper while preserving the mapped-type constraint and the necessary as NhrResponseDetails cast (still confined to one place).

NhrAdapterWithObservability.test.ts

Lines 31–229: Per-test repetition of (mockAdapter.searchDocuments as jest.Mock).mockResolvedValue({ status: 'success', documents: [] }) and new NhrAdapterWithObservability(mockAdapter, 'dmp').

This identical pair appears in ~10 tests. Hoisting the wrapper into a let wrapper initialised in beforeEach, plus a tiny helper like:

function givenSuccessfulSearch(documents: object[] = []): void {
  ;(mockAdapter.searchDocuments as jest.Mock).mockResolvedValue({ status: 'success', documents })
}

would reduce a lot of boilerplate. The MOCK_INS-only call sites also repeat { patient: { nationalHealthIdentifier: MOCK_INS }, params: {} } — a defaultProps constant or searchWithDefaults(wrapper) helper would cut another ~7 repetitions. Behaviour is identical; readability improves.

nhrMonitoring.ts

Lines 72–78: sendNhrRequest and sendNhrResponse are near-duplicates differing only in the _request / _response suffix.

Two reasonable simplifications, both behaviour-preserving:

1. Inline the suffix using the literal phase field already in the payload: ``ts const send = (details: NhrRequestDetails | NhrResponseDetails): void => { sendMonitoringEvent({ name:nhr_adapter_${details.action}_${details.phase}`, details }).catch(() => {}) } export const sendNhrRequest = (d: NhrRequestDetails) => send(d) export const sendNhrResponse = (d: NhrResponseDetails) => send(d)

`` This removes the duplicatedsendMonitoringEvent(...).catch(() => {})` line. The two named exports stay as the public surface (preserving current call sites and tests).

2. Minor: lines 4–8 have two single-line type aliases each followed by a comment about future extensions. Those comments are fine; no change needed.

nhrMonitoring.test.ts

Lines 15–84: The two describe blocks are structurally identical — three tests each (event name, details passthrough, no-throw on rejection). A small describe.each over [sendNhrRequest, sendNhrResponse] with their expected suffix would halve the file. However, this trades local clarity (each test is currently self-contained and reads top-to-bottom) for less duplication. Given the project preference for "explicit code over overly compact code" stated in the system prompt, this is borderline — I'd leave it as-is. No change recommended.

useDmpNhr.ts

No simplifications needed. The hook is already minimal: two memos, a query, and a returned object. The eslint-disable-next-line react-hooks/exhaustive-deps on line 15 is intentional (DmpApi is created once on mount).
