[WIP] Revert commit 01ebc0cd for whitelist optimization with DCO

[Copilot]

• Reset branch to base commit 01ebc0c (remove empty "Initial plan" commit)
• Revert commit 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0 with Signed-off-by trailer
• Push revert commit via report_progress

Original prompt

Background

PR #3287 (#3287) was opened via GitHub's web UI "Revert" button to revert PR #3162 (commit 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0) due to a CI failure: https://buildkite.com/vllm/vllm-omni/builds/8571/canvas

However, the revert commit on PR #3287 is missing a Signed-off-by trailer, so the DCO check fails and blocks merging. Web UI revert commits cannot be amended without rewriting history / force-pushing.

Task

Create a new pull request that reverts the same commit, with a properly signed-off commit, so it can replace PR #3287.

Requirements

1. Base branch: main
2. New branch name: revert-3162-whitelist-optimization-signed (or similar; pick something clearly distinguishable from the existing revert-3162-whitelist-optimization branch)
3. Action: Revert commit 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0 from main. You can do this with:

   git revert --no-edit 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0

   Then amend the commit to add a sign-off:

   git commit --amend --no-edit -s

   Or simply use git revert -s 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0 if your git version supports -s on revert (it does in modern git).
4. Commit message should be:

   Revert "[Config Refactor] Derive deploy override fields from stage config (#3162)"
   
   This reverts commit 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0.
   
   Signed-off-by: <your configured git author name> <your configured git author email>
   

5. Verify that the resulting commit contains a Signed-off-by: trailer (run git log -1 --format=%B to confirm).
6. The diff produced MUST exactly match the diff of PR [CI failed]Revert "[Config Refactor] Derive deploy override fields from stage config" #3287 (15 files changed, +59 / -129). Do not include any other unrelated changes.

PR description

Open the PR against main with the following body:

Reverts vllm-project/vllm-omni#3162 due to CI failure https://buildkite.com/vllm/vllm-omni/builds/8571/canvas

Re-opens #3287 with a proper DCO sign-off. Closes #3287.

Title:

[CI failed] Revert "[Config Refactor] Derive deploy override fields from stage config"

Notes

• Do NOT modify any files manually; this should be a pure git revert of the listed SHA.
• Do NOT touch the existing revert-3162-whitelist-optimization branch or PR [CI failed]Revert "[Config Refactor] Derive deploy override fields from stage config" #3287 — a maintainer will close that one manually after this new PR is opened.

The following is the prior conversation context from the user's chat exploration (may be truncated):

User: 请帮我解决这个PR的DCO问题

Assistant: 这个 PR 只有 1 个 commit，且是通过 GitHub 网页 UI 创建的 revert commit，commit message 中缺少 Signed-off-by 行，因此 DCO 检查失败：

Revert "[Config Refactor] Derive deploy override fields from stage config (#3162)"

This reverts commit 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0.

由于通过 GitHub Web UI 创建的 revert commit 没有自动加上 sign-off，且我无法仅修改 commit message 而不动 tree，最稳妥的做法是你在本地 amend 后 force-push。请执行以下命令：

# 1. 拉取分支
git fetch origin revert-3162-whitelist-optimization
git checkout revert-3162-whitelist-optimization

# 2. 用你的 DCO 身份 amend 当前 commit，加上 Signed-off-by
git commit --amend --no-edit -s

# 3. 强制推回 PR 分支
git push --force-with-lease origin revert-3162-whitelist-optimization

执行前请确认你的 git 配置与 GitHub 账户邮箱一致（DCO 要求 sign-off 邮箱与 commit author 邮箱匹配）：

git config user.name "Gao Han"
git config user.email "hgaoaf@connect.ust.hk"

push 之后 DCO 检查会自动重跑通过。

备注：如果你希望我直接通过 API 帮你修复，需要你授权 vllm-omni 仓库的写权限给我（Coding Agent），这样我可以新建一个带 sign-off 的 commit 并更新分支引用。是否需要？

User: 需要

Assistant: 抱歉，我需要更正一下之前的说法。我重新检查了我可用的工具，发现我无法通过 API 直接修复这个 DCO 问题。原因如下：

1. 我没有 Git Data API 的写权限：我能用的写操作只有 create_or_update_file 和 push_files，这两个都会在分支顶端追加新 commit，而不能 amend 已有 commit 或重写 commit message。
2. DCO 要求 PR 中的每个 commit 都签名：即使我追加一个带 Signed-off-by 的空 commit，原来那个 revert commit 仍然没签名，DCO 还是会失败。
3. 必须 force-push 重写历史：这个操作只能在本地用 git commit --amend -s + git push --force-with-lease 完成。

推荐方案

方案 A（推荐，最快）：本地一行命令搞定

git fetch origin revert-3162-whitelist-optimization && \
git checkout revert-3162-whitelist-optimization && \
git commit --amend --no-edit -s && \
git push --force-with-lease origin revert-3162-whitelist-optimization

方案 B：直接在 GitHub Web UI 上操作

1. 打开 [CI failed]Revert "[Config Refactor] Derive deploy override fields from stage config" #3287
2. 关闭这个 PR
3. 回到 [Config Refactor] Derive deploy override fields from stage config #3162 重新点击 Revert，但不要直接 commit；而是选择 "Open a pull request"，然后在分支创建后用方案 A 给那个 commit 补上 sign-off。

实际上 GitHub Web UI 的 Revert 按钮目前不支持自动 sign-off，所以最干净的还是方案 A。

如果你想让我通过 Coding Agent 帮你新开一个带 sign-off 的 revert PR（然后你关掉 #3287），可以告诉我，我会调用 coding agent 来做。但如果你能本地执行上面 4 行命令，会比新开 PR 更快。

User: 请通过 Coding Agent 帮你新开一个带 sign-off 的 revert PR

Assistant: 已派给 Coding Agent 处理。它将：

1. 从 main 创建新分支 revert-3162-whitelist-optimization-signed
2. 执行 git revert 还原 commit 01ebc0cdf542bb46db90ca8ecb641f26ca9247a0（即原 PR [Config Refactor] Derive deploy override fields from stage config #3162）
3. 在 commit message 上加 Signed-off-by 以满足 DCO
4. 开一个新 PR，body 中标注 "Closes [CI failed]Revert "[Config Refactor] Derive deploy override fields from stage config" #3287"
