Review recently modified code in the Doctolib monorepo at /Users/USER/workspace/doctolib/doctolib on branch fhir-2245_observability-search-documents for simplification opportunities. The most recent change replaced the NhrAdapterWithObservability class with a Proxy-based factory withNhrObservability.

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

Intentional patterns — do NOT suggest removing:
- Two-phase observe(action, adapterName).execute(...) pattern (TypeScript mapped-type constraint)
- as NhrRequestDetails / as NhrResponseDetails casts in execute()
- .catch(() => {}) fire-and-forget
- value.bind(target) in the Proxy get handler (preserves this for forwarded methods)
- {} as unknown as ReturnType<typeof withNhrObservability> cast in test mock

Report only simplifications that reduce complexity without changing behaviour, or say "no simplifications needed".

I'll analyze the three files for simplification opportunities while respecting the intentional patterns you've listed.

I've reviewed the three files. Respecting the intentional patterns you listed, here are the simplifications I found:

Findings

1. NhrAdapterWithObservability.ts — minor simplification available

Redundant typeof prop === 'string' check (line 91):

if (typeof prop === 'string' && prop in overrides) {
  return overrides[prop as keyof NhrAdapter]
}

The prop in overrides check already handles symbol keys safely (it just returns false for any symbol not in overrides, since overrides only has string keys). However, the typeof guard is also serving as a TypeScript narrowing aid for the as keyof NhrAdapter cast on the next line. Removing it would force a wider cast (as keyof typeof overrides works without it). The current form is defensible as a defensive guard — leave as-is.

The sendResponse inner closure (lines 34–43) is only called twice (success + error paths), but extracting it eliminates the duplicated trace_id/adapter/action/phase/duration_ms boilerplate, so this is a net win for readability — already optimal, leave as-is.

2. useDmpNhr.ts — no simplifications

The hook is already minimal: two useMemos with correct dependency arrays, a clean composition of withNhrObservability(new DmpNhrAdapter(...), 'dmp'), and a tight return shape. The eslint-disable-next-line react-hooks/exhaustive-deps on the dmpApi memo is intentional (don't recreate the API on every dmpSetUpProps reference change). No changes.

3. useDmpNhr.test.ts — one small consistency win

Line 33: mockPatient uses as unknown as Patient while line 51 (createNhrService mock) uses as unknown as ReturnType<...> and line 46/77 (useDmpSetUp mock) uses just as ReturnType<...> (single cast). The useDmpSetUp mock works with a single cast because the shape is structurally compatible. The mockPatient = { id: '1' } likely needs as unknown as Patient because Patient has many required fields — this is correct, leave as-is.

Line 42 uses the explicitly-listed-as-intentional cast ({} as unknown as ReturnType<typeof withNhrObservability>), so untouched.

The tests at lines 58–100 each call renderHook(() => useDmpNhr({ patient: mockPatient })) as the first line. This is a candidate for a small helper:

const render = () => renderHook(() => useDmpNhr({ patient: mockPatient }))

Then each test becomes render() or const { result } = render(). This is a marginal improvement (8 call sites, saves ~30 chars each), but it does reduce duplication and makes the intent (render() = "exercise the hook under test") clearer. Worth doing.

Recommendation

Apply the one test helper refactor in useDmpNhr.test.ts. Everything else is already at the right level of clarity given the constraints you specified.

Summary

Files reviewed:
- /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/business/adapters/NhrAdapterWithObservability.ts
- /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/hooks/useDmpNhr.ts
- /Users/USER/workspace/doctolib/doctolib/packages/@doctolib/national-health-records/src/hooks/useDmpNhr.test.ts

Change applied (1):
- useDmpNhr.test.ts: Extracted the duplicated renderHook(() => useDmpNhr({ patient: mockPatient })) into a top-level renderUseDmpNhr() helper used by all 8 test cases. This removes 8 repetitions of the same boilerplate, makes each test's intent clearer (one call says "exercise the hook"), and changes no behaviour.

No changes needed for:
- NhrAdapterWithObservability.ts — the two-phase observe(...).execute(...) factory, the sendResponse inner closure (deduplicates trace_id/adapter/action/phase/duration_ms between success/error paths), and the Proxy get handler with value.bind(target) are all already at the right level of abstraction. The typeof prop === 'string' guard before prop in overrides is a useful defensive check that also narrows the type for the subsequent cast — keep it.
- useDmpNhr.ts — already minimal: two useMemos, correct deps, clean composition, tight return shape. Nothing to remove without losing clarity.
