2. PR #152 expected_files 내부 hardening 6항목 적용 (회장 결정 2 scope)
3. regression 3 디렉토리 추가 (callback_owner_enforcement / callback_envelope_actual_cron_crosscheck / callback_4source_validator)
4. ANU normal callback 4-source 검증 envelope 박제 (`memory/events/anu_callback/task-2693-normal-completion.json`)

## 범위

### 포함 (PR #152 내부 한정)
- `dispatch/normal_fallback_callback_helper.py` — line 92, 753, 811 isinstance/mismatch 수정
- `dispatch/prompt.py` — line 48 sid validation
- `schemas/anu_normal_callback_envelope_v1.json` — canonical_root const→pattern
- `utils/callback_authority_4source_validator.py` (신규) — 4-source 검증기
- `utils/anu_callback_registrar.py` — ANU key 강제 (self-key fail-closed) 강화
- `utils/pr_watcher_terminal_state_classifier.py` — AUTHORITATIVE_BUT_SESSION_DISCONTINUITY enum 보강

## 위임 계획

- **Phase 1 (구현)**: **토르(backend)** — Thread 1+3 (HIGH mismatch fix), Thread 4 (explicit isinstance), Thread 5 (isinstance defense), Thread 2 (prompt sid validation), Thread 6 (schema const→pattern), callback_authority_4source_validator.py 신규
- **Phase 2 (Regression)**: **헤임달(tester)** — 3 regression 디렉토리 작성 + pytest 통과
- **Phase 3 (통합/검증)**: **오딘** — pytest 회귀 + 6조건 평가 작성 + envelope 박제 + thread resolve

## 검증 기준

- pytest: `python3 -m pytest tests/regression/callback_session_propagation tests/regression/callback_owner_enforcement tests/regression/callback_envelope_actual_cron_crosscheck tests/regression/callback_4source_validator -q` → 0 fail
- 6조건 평가 thread별: 모두 PASS → X1 자동수렴 허용
- envelope 3 SID = `53e89540-5bed-4692-a726-ed857820758a` 일치 + ANU key `c119085addb0f8b7`
- forbidden_action_count = 0
- PR #154/PR #151/task-2691+b 혼합 = 0 evidence
