端到端 haiku 考 0/3、1/3 的斷點在教材不在引擎——MCP instructions 是 AI 一連上就讀到的
最前置教材，卻寫死「沒有 ON_TRUE／ON_FALSE／ON_BRANCH——引擎目前不支援條件分支」，
與實際行為相反（探針實測分支正常）。考生據此判定「不支援」而退回寫 code。

本包變更（產物實查）：
- tier2/mcp：舊「不支援條件分支」**歸 0**；新「2026-08-01 起引擎支援」2 處；
  新增「分支跑完怎麼判斷成功」段（走 true 路時 false 路節點不出現＝正確行為非失敗）
- publish_component 在產物內**歸 0**（#23 死代碼已 git rm）
- tier1／cypher 未變（本次只動教材與 MCP），core 維持 24、daemon 仍 v0.15.0
