workflow: the review step posts a second Verdict PASS at an unchanged tip #1798
Description
Written-by: Chief
The 变脏修复线 (wf-957f985b) posted two Verdict: PASS conclusions at the same tip on PR #1772, and the pull request then merged. AGENTS.md says one tip carries at most one conclusion; a second one is an incident.

What happens today: merge-gate reads the newest conclusion at the tip (review-gate newest-wins), so a duplicate PASS is not fatal — the merge went through on the second one. The defect is that the rule "one conclusion per tip" is a convention the gate only encodes as newest-wins, so a node that re-enters review writes a second conclusion at an unchanged tip and nobody notices. On this run the re-entry looks like the enqueue node coming back to review after the first PASS (the two bodies differ in length, so it is a re-post, not a retried HTTP write).
What the repair line should do:
- In the 变脏修复线 graph, make
reviewrefuse to post when aVerdict:already names the current tip, and print one line saying it reused the existing conclusion (that is a code change in the review step's prompt/library, not a workflow-graph edit alone; if it is prompt-only, then the prompt must state it and a test must prove the second post is refused). - Same for the issue 快线
wf-1cdf6ec5and the PR 快线wf-7ed167b6, since the review step is shared. - Do not relax the gate: the fix is "do not write a second conclusion", not "accept two".
Acceptance: a run whose review node is entered twice at an unchanged tip leaves exactly one Verdict: comment at that tip, and the run reports the reuse in its summary.
Related: #1773 (a step that prints no OUTPUT is still recorded as done).

判定：可开工（promote） — 缺陷有实据：PR #1772 同一 tip
5ea9acbb023a3e119c353437cfb87d021cf5765e上两条首行结论，Verdict: PASS分别于 05:17:27Z 与 05:21:24Z。门语义不动：merge-gate的 newest-wins 保持原样，改的只是「不写第二条结论」。要改的文件
.github/scripts/review-once.mjs（新）：alreadyConcluded({ comments, tip })—— 复用review-gate.mjs导出的parseReport认「首行 Verdict 且名字是当前 40 位 tip」，不再写第二套解析；postOnce({ pr, tip, body })—— 先GET /repos/ThinkFlowLab/FlyBot/issues/{pr}/comments?per_page=100，命中就打一行reused conclusion at <tip>并 exit 0、不发 POST；未命中才POST …/comments。token 走$DSH_SECRET_GITHUB_TOKEN，不打印。.github/scripts/review-once.test.mjs（新）：三条用例 —— 无结论 → 发 1 条；同 tip 已有 → 0 次 POST、输出恰一行 reused（exit 0）；不同 tip 已有 → 照发。review节点 prompt（wf-957f985b、wf-1cdf6ec5、wf-7ed167b6）改成贴结论前先调用这个脚本。这三份定义在运行时 store（/data/dsh/bot/flybot-workflow/workflows.json），不进 PR，由改图的一方同轮接上；PR 只包含 1、2。验收命令
接上 prompt 后另做一次 run 级验证：review 节点在同一 tip 被进两次，PR 评论里恰好一条
Verdict:，run 摘要有一行 reused。红先怎么写
先写第 2 条用例（同 tip 已有结论），做一个只发 POST 的桩实现，断言「0 次 POST + 一行 reused」→ 现在会发第二次 → 红；再加
alreadyConcluded守卫 → 绿。第 1、3 条护住正常路径，防止把该发的结论也堵死。Birfy commentedon Oct 30, 2026
