AutoPOE2 - Multimodal Flight Recorder (Incident Dossier Packaging)
Tuân thủ nghiêm ngặt:
- Rule 8: Triệt tiêu sửa lỗi triệu chứng (Root-Cause-First).
- Rule 11: Phòng ngừa hồi quy (Automated Regression Prevention).
- Rule 13: Giao thức Watcher thời gian thực & Tự sửa lỗi khép kín (6-Stage Closed-Loop).
- Rule 14: Tuyệt đối cấm dùng mock data / bịa data — 100% dữ liệu thật (Real Authentic Data Protocol).

Đóng gói hồ sơ sự cố (Incident Dossier) tại thời điểm 0ms vào thư mục:

Gồm 6 thành phần:
  1. incident_dossier.json (Chuẩn schema Doc 17)
  2. screenshot.png
  3. annotated_correlation.png
  4. ram_dump.json & ram_snapshot.json
  5. core_log_slice.txt
  6. companion_log_slice.txt
