   - Import `{ parseMessage, convertADT_A03 }` and test utilities
   - Describe block: `"convertADT_A03 - discharge converter"`

   - Test 2: "with missing PV1-19 returns conversion_error" — omit PV1-19, assert `conversion_error` status
-  - Test 3: "with valid NK1/DG1/AL1/IN1 includes all resource types" — add optional segments, assert array lengths
-- [ ] Test 4: Smoke test (name prefix `"smoke: ADT_A03 discharge"`) using de-identified example-01.hl7 from `ai/tickets/converter-skill-tickets/adt-a03-discharge/examples/` — assert status `processed` or `warning`, Encounter.status `finished`, Patient created
