- chain-composer: 删 filterDiscoveredByPatientLevel(无调用,doc 复位给 markAlternativeClosed)、
  collectS1Facts、_S2_PAYMENT_THRESHOLD_CENTS_DEPRECATED(+void 语句)、ComposeInputEncounter 兼容别名
- plan-aggregate: 删 PatientWithProfile/Fact/loadFactStub 自引用死类型链(declare-only)
- admin.dto: 删 CreateHostRequestDto/CreateHostResponseDto/AiInvocationListItemDto 未用包装类 + 对应 schema import
- skill-registry: 删未用 getSkill
- mock-data(web): fmtDate 去 export(仅内部用)

service + web tsc 通过。
