Subject: [PATCH 01/13] Record the task card for
 feature-cli-agent-fallback-chain

Why: establish the authorized task workspace and its initial baseline.

Evidence: preserved precheck receipt in .task/feature-cli-agent-fallback-chain.md; R0=d2035c76dc1cb15e01d2c184af5155d9d773cd9f.

Impact: task metadata only; the feature workspace starts at d2035c76dc1cb15e01d2c184af5155d9d773cd9f.

 ## 结果与验证（完成后填写）
 
-- 结果：
-- 验证：<结论摘要 PASS/FAIL/SKIP/NOT_RUN 逐项；逐条证据由 make evidence 写入上方证据表>
-- 影响与剩余项：
+- 结果：四个角色候选链为 cursor(auto) → antigravity(`gemini-3.8-flash-high`) → pi-glm(`zai-coding-cn/glm-5.3-flash`) → pi(`minimax-cn/MiniMax-M3`) → codex(`gpt-6.1-sol`)（test/review 前四项顺序不同，Codex 均最后），每候选最多 3 次；去掉 `emergency_profile`；policy 三份文本同步“自动换候选不询问、全部耗尽暂停询问是否重试”。
+- 验证：`make agent-exec-validate` PASS；`make test-governance` PASS（513 tests，skipped=18）；`make task-sync` PASS；三个新模型 ID 冒烟 PASS（SELF，未入证据表）；PR HEAD 完整 CI 待 GATE。
+- 影响与剩余项：仅影响 Agent 执行路由。运行时随机顺序未实现（非目标，声明顺序满足“顺序不限、Codex 最后”）；`failed-unknown` 等 fail-stop 仍立即停止、不换候选。

Subject: [PATCH 13/13] Fold-close the task card before merge
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Why: close the task card inside its own PR so landing it needs no post-merge backfill or separate close PR.
Evidence: .task/feature-cli-agent-fallback-chain.md -> .task/archive/feature-cli-agent-fallback-chain.md; status 已完成（合入前闭合）; PR #648 https://git-home.u1680832.nyat.app:30319/weichen/Agent-System-Dev/pulls/648.
Impact: task metadata only; the card is archived within PR #648 and lands with its merge commit.
Refs: task.sh close --self
