# Fixture Provenance: unknown_insufficient

## 출처
합성(synthetic) fixture. 실 live evidence 없음.

## 목적
회장 보강 D(UNKNOWN/INSUFFICIENT_EVIDENCE + evidence_completeness) 검증용.

## 핵심 사실
- core evidence 소스(result_json, schedule_history, collectors) 전부 부재
- doctrine: "증거 없으면 추정 금지 → UNKNOWN"
- `evidence_completeness = MISSING`
- `delivery_outcome = UNKNOWN_INSUFFICIENT_EVIDENCE`
- `normal_callback_miss_cause = UNKNOWN_INSUFFICIENT_EVIDENCE`
- `root_cause_tags = []` (추정 불가)
