Sample artifacts (KOZU) — đối chiếu template

Stage	Sample artifact	Template tương ứng	Nội dung

UC	uc-chat-01 · uc-parse-01	08-use_cases	13-field Cockburn, validate-uc 18/20

MD	equipment-qna-sequence.mermaid	10-screen_transition	sequence 14 bước, render PNG 48KB

Khác biệt cốt lõi vs Migration: greenfield không có bước SCAN/reverse-engineer + legacy-map — bắt đầu thẳng từ RD trên brief. Template/sample dùng chung pack 74 template, chỉ khác bộ nào được dùng ở mỗi stage.
