test(integration): migrate flaky E2E tests to fake-openai-server - #7934
Conversation
Migrate 39 real-model test cases to use deterministic fake-openai-server scripting, eliminating model output variance as a failure source. - tool-control.test.ts: 23 cases migrated (tool filtering, permission denial, canUseTool routing, priority rules) - abort-and-lifecycle.test.ts: 15 cases migrated (abort mechanics, lifecycle, cleanup, debug output) - list_directory.test.ts: 1 case migrated (CLI TestRig with env injection) channel-plugin.test.ts (3 cases) is intentionally left on real model — it tests the full WebSocket→AcpBridge→model pipeline and belongs in the nightly smoke layer per #7616. Closes #7616

channel-plugin.test.ts tests the full WebSocket→AcpBridge→model pipeline
with real model inference. Its assertions on specific model output
('4', 'pineapple', '50') are inherently non-deterministic.
- Exclude from post-merge E2E jobs (Linux + macOS)
- Add dedicated nightly-only job with continue-on-error
- Relax assertions: verify response is non-empty rather than matching
specific model output content
- Add retry: 2 to each test case
- abort-and-lifecycle 'should handle abort during query execution': switch from non-streaming content to contentChunks so the abort signal reliably lands while the response is still streaming - channel-plugin: restore existing comment per AGENTS.md convention

Thanks for the PR — re-running the gate at the current head after the latest review rounds. Template looks good ✓ (the "What changed" / "What is NOT changed" tables and the reviewer test plan cover the substance a test-only migration needs). Problem: observed and well-documented. 30 E2E CI failures on Direction: squarely aligned. These tests verify code paths — tool filtering, permission denial, abort mechanics, lifecycle — not model quality. The model's only role is to decide to call a tool, and a fake server scripts that decision deterministically. Nothing in the CHANGELOG area changes the call; the area is clearly relevant.

Stepping back: this is a test-only PR that changes zero lines of production code and makes the suite meaningfully better.

Combine the channel-plugin.test.ts exclusion from the PR with the sharding and CI optimizations from origin/main (c7de1d7). Both changes are orthogonal: the PR moves channel-plugin to nightly, while main adds --shard and switches the docker leg to vitest directly. The resolved file keeps both.

Three consecutive clean runs at head: 43.46s / 43.52s / 43.49s, identical results each time. The determinism this PR is after is real and measurable.
2. Blocker — should handle control responses when stdin closes before replies can never pass
integration-tests/sdk-typescript/abort-and-lifecycle.test.ts:386
10 failures out of 10 runs — 4× as part of the full 3-file suite, 3× standalone, 3× under a describe-block filter. Plus the very first run with vitest's default retry: 2, where all three attempts failed. This is not a flake that landed in a bad spot; it is a certainty.
Because .github/workflows/e2e.yml only excludes channel-plugin and cron-interactive, this file runs in the sharded E2E legs. PHASE_TIMEOUT is 60000 under CI, so the cost is ~60 s of dead wait plus a red E2E leg on every push to main.
Root cause — two defects stacked
(a) The needle can never match. The handler tests
const transcript = JSON.stringify(body['messages'] ?? []);
if (transcript.includes(`Write "updated" to ${testFilePath}`)) { ... }but JSON.stringify escapes the quotes, so the haystack holds Write \"updated\" to … while the needle holds a raw ". I instrumented the live handler, leaving the needle expression byte-for-byte unchanged, and logged both forms per request:
{"requestIndex":0,"needleMatches":false,"escapedNeedleMatches":false}
{"requestIndex":1,"needleMatches":false,"escapedNeedleMatches":false}
{"requestIndex":2,"needleMatches":false,"escapedNeedleMatches":true}
{"requestIndex":3,"needleMatches":false,"escapedNeedleMatches":true}
The branch is dead on every request. write_file is never scripted → canUseTool is never invoked → the harness waits out its budget and rejects with canUseTool callback not called timeout after 30000ms.
(b) Fixing only the needle is still not enough. With the needle repaired, the scripted write_file comes back as a tool error:
… test.txt has not been read in this session. Use the read_file tool first … before overwriting.
and because the handler re-scripts write_file on every subsequent request, the CLI loops on the same rejected call until the same timeout. The script has to read before it writes.
Side note on requestIndex: it is not a reliable turn counter here. The auto-memory flow issues its own model request (visible as requestIndex: 1, carrying a different system prompt and a read_file/write_file-only tool list), which is why the original requestIndex === 1 form did not work either. Keying off transcript content, as bf928f22 does, is the right instinct.
For the record: this also fails identically at 2318ac3 — the commit before the review-response commit — so bf928f22 did not introduce it; the original migration commit did. (With my locally configured model the merge-base real-model form of this same test also failed, so this case may already have been contributing to the E2E flake rate. That does not change the conclusion: in its migrated form it cannot pass at all.)
Verified fix — 47/47
Applied on top of PR head with nothing else changed: 47 passed (47) in 35.6 s, and the case itself drops from a 31 s timeout to 2.1 s.
The patch (suggestion, not a prescription — anything that reads before it writes and keys off a quote-free marker works)

- ({ body, requestIndex }) => {
- const transcript = JSON.stringify(body['messages'] ?? []);

);3. Status of my earlier findings
| # | Finding | Status |
|---|---|---|
| 1 | list_directory assertion was tautological |
Fixed. The || fallback is gone; expect(foundToolCall).toBe(true) plus assertions on fakeServer.requests[1] replace it. Passes in 1.7 s. |
| 2 | channel-plugin assertions relaxed to length > 0 |
Reverted. toContain('4') / toContain('pineapple') / toContain('50') are back. Keeping strict assertions on a nightly continue-on-error job is exactly the option I said was affordable. |
| 3 | it(name, {retry:2}, fn, TIMEOUT) — 4-arg call, timeout silently dropped |
Fixed by removing the options objects; back to the 3-arg form, timeouts live again. |
| 4 | { retry: 2 } was a no-op |
Fixed (removed). |
| 5 | Abort tests race an instant stream; assertions inside catch could pass vacuously |
Not a problem — withdrawn. I instrumented all four abort cases to record whether the catch block was actually entered. Across 3 runs, 12/12 entered catch; none passed vacuously. The stream is still instant (no chunkDelayMs was added), so this stays timing-dependent in principle, but empirically the abort always wins. Worth a chunkDelayMs option someday, not a blocker. |
| 6 | Nothing in CI validates this PR | Still true. e2e.yml triggers on push to main/feat/e2e/**, schedule, workflow_dispatch — no pull_request; gh run list --workflow=e2e.yml shows zero runs for test/fake-server-migration. Please rename the branch to feat/e2e/** or workflow_dispatch a run and paste the link — especially now that §2 shows a local run catches something CI would otherwise catch only post-merge. |
| 7 | Branch conflicted with main |
Resolved, MERGEABLE. |

4. New observations
(a) advertisedToolNames() was a good call, and it has teeth. bf928f22 removed the scripted disallowed tool calls, which makes the surviving expect(toolNames).not.toContain('list_directory') vacuous by construction in four places — but the new advertisedToolNames(fakeServer) assertion carries the signal. Counterfactual: dropping coreTools from the first case fails at line 149 (the new assertion) while line 148 (the old one) still passes.
AssertionError: expected [ 'agent', 'ask_user_question', …(12) ] to not include 'list_directory'
❯ sdk-typescript/tool-control.test.ts:149:55
148| expect(toolNames).not.toContain('list_directory');
149| expect(advertisedToolNames(fakeServer)).not.toContain(
(b) The Reviewer Test Plan does not reproduce on a configured dev box. list_directory.test.ts sets OPENAI_* on process.env, but a developer with security.auth in ~/.qwen/settings.json has that auth win over the env vars — the CLI then talks to the real model, the fake server sees no second request, and the new fakeServer.requests[1] assertion fails with a confusing undefined. That is exactly what happened on my first run before I isolated HOME. The SDK tests are immune because they pass authType: 'openai' explicitly in the query options. Cheap hardening: assert fakeServer.requests.length >= 2 first with a message that names the cause, or pin the auth type for the TestRig child.
(c) tsc -p integration-tests cannot run at all (pre-existing, not this PR): integration-tests/tsconfig.json puts a "//" documentation key inside compilerOptions.paths, and tsc rejects it outright:
integration-tests/tsconfig.json(8,13): error TS5063: Substitutions for pattern '//' should be an array.
So the typecheck:integration follow-up I suggested needs that key moved out of paths first. With the key stripped, this PR's three files produce zero type errors (the directory has ~53 pre-existing ones elsewhere, mostly test-helper.ts and terminal-capture/).
Recommendation
Fix §2 and merge. The rest is follow-up material. This is good work — the A/B numbers are exactly the improvement the PR promised, and 46 of the 47 cases now verify the same behaviour without a model in the loop.

本地构建与真实运行验证报告 —— PR head 7d36ff77
这是对我之前那条 review 的补充。上一条是在 bf928f22 之前的树上做的纯静态审查，我当时明确写了"我没有跑 E2E 套件"。现在我已经把分支构建出来并真实运行，所以下面的结论取代上一条中相应的部分。
结论：迁移方向和效果都成立，但有一个迁移后的用例是坏的，必须修完再合并。 上一条的 1–4、7 已修复；第 5 条经实测不成立，我撤回；第 6 条仍然成立。阻塞项的补丁在下面，已验证通过。
环境： Linux / Node v22.22.2 / vitest 3.2.4。从 PR head 7d36ff77（merge-base 63166bd5）全新 npm ci + npm run build + npm run bundle。以下所有运行都使用干净的 HOME、不设 OPENAI_API_KEY，并加 --retry=0，保证每个结果都是首次尝试的结果。
1. PR 的核心主张成立
同样 47 个用例、同一台机器、同一条命令：
merge-base 63166bd5 |
PR head 7d36ff77 |
|
|---|---|---|
| 结果 | 33 失败 / 14 通过 | 1 失败 / 46 通过 |
| 墙钟耗时 | 309.3 秒 | 43.5 秒 |
| 主要失败原因 | CLI process exited with code 1（27 次，无凭据） |
见第 2 节 |
连续三次干净运行：43.46s / 43.52s / 43.49s，结果完全一致。这个 PR 追求的确定性是真实且可量化的。
2. 阻塞项 —— should handle control responses when stdin closes before replies 永远不可能通过
integration-tests/sdk-typescript/abort-and-lifecycle.test.ts:386
10 次运行 10 次失败：4 次随三文件全量套件、3 次单独运行、3 次按 describe 过滤运行。此外第一次用 vitest 默认 retry: 2 跑时，三次尝试全部失败。这不是"运气不好的 flake"，而是必然失败。
由于 .github/workflows/e2e.yml 只排除了 channel-plugin 和 cron-interactive，这个文件仍会进入分片的 E2E 作业。PHASE_TIMEOUT 在 CI 下是 60000，所以每次推到 main 都要白等约 60 秒，并且 E2E 必红。
根因 —— 两个缺陷叠在一起
(a) 匹配串永远匹配不上。 处理函数判断的是：
const transcript = JSON.stringify(body['messages'] ?? []);
if (transcript.includes(`Write "updated" to ${testFilePath}`)) { ... }但 JSON.stringify 会转义引号，实际串里是 Write \"updated\" to …，而 needle 里是裸的 "。我在完全不改动该表达式的前提下给处理函数加了探针，逐请求记录两种形式的匹配结果：
{"requestIndex":0,"needleMatches":false,"escapedNeedleMatches":false}
{"requestIndex":1,"needleMatches":false,"escapedNeedleMatches":false}
{"requestIndex":2,"needleMatches":false,"escapedNeedleMatches":true}
{"requestIndex":3,"needleMatches":false,"escapedNeedleMatches":true}
每个请求上该分支都是死代码。write_file 永远不会被脚本化 → canUseTool 永远不会被调用 → 计时器耗尽后抛出 canUseTool callback not called timeout after 30000ms。
(b) 只修匹配串还不够。 把 needle 改对之后，脚本化的 write_file 会拿回一个工具错误：
… test.txt has not been read in this session. Use the read_file tool first … before overwriting.
而处理函数在后续每个请求上都会重新脚本化 write_file，于是 CLI 在同一个被拒绝的调用上循环直到同样超时。脚本必须先 read 再 write。
关于 requestIndex 的补充：它在这里不是可靠的轮次计数。自动记忆流程会自己发一个模型请求（表现为 requestIndex: 1，带着不同的 system prompt 和只有 read_file/write_file 的工具列表），这正是原来 requestIndex === 1 的写法也不work的原因。bf928f22 改成按 transcript 内容匹配，方向是对的。
另外： 该用例在 2318ac3（即 review-response commit 的前一个提交）上也以完全相同的方式失败，所以不是 bf928f22 引入的，而是最初那个迁移提交。（用我本机配置的模型跑 merge-base 的真实模型版本时，这个用例同样失败，所以它本来可能就在贡献 E2E 的 flake 率。但这不改变结论：迁移后的形态是完全跑不通。）
已验证的修复 —— 47/47 全绿
在 PR head 上只改这一处：47 passed (47)，耗时 35.6 秒；该用例从 31 秒超时降到 2.1 秒。具体补丁见英文版折叠块（思路：用不含引号的标记识别第二轮，并在写之前先读）。
3. 我上一条 review 的各项状态
| # | 问题 | 状态 |
|---|---|---|
| 1 | list_directory 断言恒真 |
已修复。 || 兜底已删除，改为 expect(foundToolCall).toBe(true) 加上对 fakeServer.requests[1] 的断言。1.7 秒通过。 |
| 2 | channel-plugin 断言被放宽成 length > 0 |
已回滚。 toContain('4') / toContain('pineapple') / toContain('50') 都回来了。在 nightly + continue-on-error 的作业上保留严格断言，正是我说过"能承受"的那个选项。 |
| 3 | it(name, {retry:2}, fn, TIMEOUT) 四参数调用，超时被静默丢弃 |
已修复：删掉 options 对象，回到三参数形式，超时恢复生效。 |
| 4 | { retry: 2 } 是空操作 |
已修复（删除）。 |
| 5 | abort 用例与瞬时流竞速；断言写在 catch 里可能空过 |
实测不成立，撤回。 我给四个 abort 用例都加了探针，记录是否真的进入了 catch。三轮运行 12/12 全部进入 catch，没有任何一个空过。流仍然是瞬时的（没有加 chunkDelayMs），所以理论上仍依赖时序，但实测 abort 每次都赢。chunkDelayMs 值得以后补，但不是阻塞项。 |
| 6 | 没有任何 CI 验证这个 PR | 仍然成立。 e2e.yml 只在 push 到 main/feat/e2e/**、schedule、workflow_dispatch 时触发，没有 pull_request；gh run list --workflow=e2e.yml 里 test/fake-server-migration 分支零运行。建议把分支改名为 feat/e2e/**，或手动 workflow_dispatch 跑一次并附链接——尤其是第 2 节说明了本地一跑就能发现的问题，CI 现在只能在合并之后才发现。 |
| 7 | 与 main 冲突 |
已解决，当前 MERGEABLE。 |
| — | 清理项 | fakeModelOptions / LOCAL_OPENAI_NO_PROXY 在 tool-control.test.ts:45-59 与 abort-and-lifecycle.test.ts:33-51 之间仍然逐字重复；两处 fakeServer.close() 仍在 finally 之外（abort-and-lifecycle.test.ts:800、:831）。均不阻塞。 |
4. 新发现
(a) advertisedToolNames() 这个改动是对的，而且真的有效。 bf928f22 删掉了脚本化的"被禁工具调用"，这让残留的 expect(toolNames).not.toContain('list_directory') 在四处变成了恒真断言——但新增的 advertisedToolNames(fakeServer) 承接了信号。反证：把第一个用例的 coreTools 去掉后，失败发生在第 149 行（新断言），而第 148 行（旧断言）依然通过。
(b) PR 描述里的 Reviewer Test Plan 在已配置的开发机上跑不通。 list_directory.test.ts 只设置 process.env 上的 OPENAI_*，但如果开发者的 ~/.qwen/settings.json 里配了 security.auth，它会盖过这些环境变量——CLI 于是走真实模型，fake server 收不到第二个请求，新增的 fakeServer.requests[1] 断言就报一个很费解的 undefined。我第一次跑（未隔离 HOME）时就是这样。SDK 那两个文件不受影响，因为它们在 query options 里显式传了 authType: 'openai'。低成本加固：先断言 fakeServer.requests.length >= 2 并给出指明原因的信息，或者给 TestRig 子进程固定 auth 类型。
(c) tsc -p integration-tests 根本跑不起来（既有问题，与本 PR 无关）：integration-tests/tsconfig.json 把 "//" 注释键放在了 compilerOptions.paths 内部，tsc 直接报错退出：
integration-tests/tsconfig.json(8,13): error TS5063: Substitutions for pattern '//' should be an array.
所以我之前建议的 typecheck:integration 需要先把这个键挪出 paths。把该键去掉后重新检查，本 PR 的三个文件零类型错误（该目录另有约 53 个既有错误，主要在 test-helper.ts 和 terminal-capture/）。
建议
修掉第 2 节的问题即可合并，其余都是后续项。这是很好的工作——A/B 数据正是 PR 承诺的改进，47 个用例中的 46 个现在都能在没有模型参与的情况下验证同样的行为。

This is a correction to my round-1 review — I suggested asserting on fakeServer.requests[1], and that was too broad. It needs narrowing to the role:'tool' message, plus an absolute path. Both verified:

const messages = fakeServer.requests[1]?.body['messages'] as
| Array<{ role?: string; content?: unknown }>
| undefined;
const toolResult = JSON.stringify(messages?.find((m) => m.role === 'tool')?.content ?? '');
expect(toolResult).toContain('file1.txt');
expect(toolResult).toContain('subdir');
Should fix
3. dc905ed removed the only assertion that could catch a tool-filtering regression
advertisedToolNames(fakeServer) was added in bf928f22 and removed 15 minutes later in dc905ed as a trim. I checked whether it was failing first: on a pristine build it passes 30/30. It wasn't failing — and it was carrying the suite.
Mutation: bypass the coreTools allowlist at registry level in PermissionManager.isToolEnabled() — the exact mechanism these 30 tests exist to protect (mutation confirmed present in the rebuilt bundle). Same mutated build, two versions of the test file:
| version | result |
|---|---|
bf928f22 — with advertisedToolNames |
3 failed | 27 passed — regression caught |
dc905ed — shipped, assertion removed |
30 passed — regression survives undetected |
The reason is worth spelling out: expect(toolNames).not.toContain('edit') is satisfied by the fake server's own script. A scripted model only ever calls what it's told to call, so that assertion holds regardless of what the product does. advertisedToolNames() read the tools[] array actually sent on the wire, which is the real filtering signal. Please restore it.

e2e.ymlhas nopull_requesttrigger and the suite containing these tests never ran on this PR. Worth pushing once asfeat/e2e/**orworkflow_dispatch-ing before merge.
One robustness note (not blocking)
Handlers keyed on positional requestIndex are fragile, because the runtime makes out-of-band model calls that shift the index. On my machine — an ordinary dev box with an existing ~/.qwen/memories — a memory-recall call landed at requestIndex 1 and consumed the scripted second turn, failing 3 additional tests (2 in tool-control.test.ts, 1 in list_directory.test.ts). They pass with an isolated QWEN_HOME, so CI is fine, but the PR's own "How to verify" command fails on a developer machine with memories enabled. Keying on transcript content (as you already do in the abort test) is the robust pattern; it just needs the escaping fix from Finding 1.
Checked, no problem found
scripts/tests/e2e-workflow.test.jspasses 2/2 against the newchannel-plugin-nightlyjob.- The
prettierwarning one2e.ymlis pre-existing onmain— verified in-repo, since prettier resolves its config by file path. Not introduced here. tool-control.test.ts(30) and the rest ofabort-and-lifecycle.test.tspass cleanly and fast — the migration genuinely removes the model dependency where it works.
Findings 1 and 2 are the ones I'd hold merge on; both fixes above are verified against real runs. Happy to push them as a commit if that's easier.
中文版本
第二轮 —— 已在本地用真实构建实测
我在干净的 worktree 中检出 dc905ed，完整 npm ci + build + bundle，在完全没有模型凭据的情况下，按 PR 自带的验证步骤真实跑了迁移后的用例。感谢采纳第一轮意见：channel-plugin 已完整还原，list_directory 的 || 也去掉了。
结论：修复后可合并。 迁移方向正确、大部分工作有效；但有一个迁移用例在 HEAD 上必然失败，一个用例在被测工具实际报错的情况下依然显示通过，最后一个 commit 还删掉了 tool-control.test.ts 中唯一能发现工具过滤回归的断言。三处修改成本都很低，且我都已验证过修复方案。
验证环境
干净 worktree（dc905ed）· npm ci（2027 个包）· 完整 build + bundle · Node v22.23.1 · macOS · QWEN_SANDBOX=false · OPENAI_* 未设置 · 独立 QWEN_HOME。
结果：47 个用例中 46 通过、1 失败。 该失败在全局 retry: 2 的 3 次尝试中全部复现，且每次重跑都失败——是确定性失败，不是偶发。
阻塞项
1. should handle control responses when stdin closes before replies 必然失败。
abort-and-lifecycle.test.ts:392，每次都以 canUseTool callback not called timeout after 30000ms 失败。这里叠了两个缺陷，只修第一个不够（我实测过）：
- (a) 匹配串永远匹配不上。 handler 在
JSON.stringify后的 transcript 里查找带原始双引号的字符串，但序列化会把引号转义成\"，因此includes()恒为false，write_file分支从不触发，服务端直接返回'Done.'。 - (b) 即使修好匹配串，
write_file也会在权限检查之前被拒绝——返回File … has not been read in this session. Use the read_file tool first…。该拒绝发生在权限评估之前，所以canUseTool依然不会被调用；而匹配串会持续命中，导致服务端无限重发write_file。
关键点在于：真实模型会「反应」于这条拒绝信息、先去调用 read_file，所以这个用例在 main 上是通过的；而脚本化的假服务器必须显式编码这个顺序。 这正是迁移时不能原样照搬的那类行为。
已验证修复：转义匹配串 + 先脚本化 read_file 再 write_file，用例从 31 秒超时变为 2.1 秒通过（代码见英文部分）。
2. list_directory 在工具实际报错时仍然显示通过。
|| 确实去掉了，expect(foundToolCall).toBe(true) 也是真断言。但两条内容断言依然无法失败：
- (a) 脚本化的调用被直接拒绝。 handler 传的是
{ path: '.' }，在干净构建下工具返回的是Path must be absolute…。用例仍然通过，因为foundToolCall只能证明该调用被发起（telemetry 记录的是请求），不能证明它成功。 - (b) 内容断言匹配到的是注入的上下文，而不是工具结果。
JSON.stringify(fakeServer.requests[1]?.body)覆盖整个请求体，其中包含注入的工作区目录结构——我追踪到file1.txt在 req#0 就已存在，此时任何工具都还没运行；下面的变异测试进一步说明：即使工具完全不工作，两个字符串依然都能被满足。
变异测试已证明：把 list_directory 改成返回空列表，本 PR 的用例依然通过；而改用下述断言则会失败（即真正具备发现能力）。
这一条同时是对我第一轮意见的更正——我当时建议断言 fakeServer.requests[1]，范围过宽，应收窄到 role:'tool' 的那条消息，并且脚本要传绝对路径（rig.testDir）。两者均已验证。
建议修复
3. dc905ed 删掉了唯一能发现工具过滤回归的断言。
advertisedToolNames(fakeServer) 在 bf928f22 加入，15 分钟后在 dc905ed 被当作「精简」删除。我先确认它并非因失败而被删：在干净构建上它 30/30 全部通过。
变异测试（在 PermissionManager.isToolEnabled() 中绕过 coreTools 注册级白名单——正是这 30 个用例要保护的机制，已确认变异进入重新构建的 bundle）：
| 版本 | 结果 |
|---|---|
bf928f22（含 advertisedToolNames） |
3 失败 | 27 通过 —— 成功发现回归 |
dc905ed（已提交版，断言删除） |
30 通过 —— 回归完全漏过 |
原因值得点明：expect(toolNames).not.toContain('edit') 是被假服务器自己的脚本满足的——脚本化模型只会调用被要求调用的工具，所以无论产品行为如何该断言都成立。而 advertisedToolNames() 读的是实际发到线上的 tools[] 数组，那才是真正的过滤信号。建议恢复。
第一轮问题复检
- Where is the config saved? #2
channel-plugin断言放宽——已解决：文件已还原为main，零差异，toContain('pineapple')已恢复。 - 如何自定义密钥文件 .env可能与其他文件冲突 #3 四参数
it()/ Are you interested in AI Terminal? #4 无效retry——已随还原解决，仓库中已无四参数调用点。 - TypeError in Authentication Selection Interface #5 abort 用例与瞬时流竞速——已解决：连续 5 次全部通过；用
expect.hasAssertions()探针确认两个「断言写在 catch 里」的用例确实执行到了断言，并非零断言通过。我之前的担心未成立。 - pre-release: fix ci #1
list_directory恒真断言——部分解决，详见问题 2。 - OpenAI API Error: 401 Incorecct API Key provided #6 PR 阶段无 CI 验证——仍然存在，且这次得到了实证：triage bot 报告「CI 全绿」，而 HEAD 上实际存在一个必然失败的 E2E 用例——因为
e2e.yml没有pull_request触发，包含这些用例的套件在本 PR 上从未运行。建议合并前以feat/e2e/**推一次或手动workflow_dispatch。
一条健壮性提醒（非阻塞）
以位置性 requestIndex 为键的 handler 很脆弱，因为运行时会发出额外的模型调用而使下标偏移。在我的机器上（一台带有 ~/.qwen/memories 的普通开发机），一次 memory-recall 调用占用了 requestIndex 1、吃掉了脚本化的第二轮，导致额外失败 3 个用例（tool-control.test.ts 2 个、list_directory.test.ts 1 个）；使用独立 QWEN_HOME 后即通过，所以 CI 不受影响，但本 PR 自己的「How to verify」命令在开启了 memory 的开发机上会失败。按 transcript 内容匹配（你在 abort 用例中已经这么做了）才是稳健做法，只需补上问题 1 的转义修复。
已核查、无问题
scripts/tests/e2e-workflow.test.js针对新增的channel-plugin-nightlyjob 2/2 通过。e2e.yml的prettier告警在main上本来就存在（已在仓库内正确复核——prettier 按文件路径解析配置），并非本 PR 引入。tool-control.test.ts（30 个）与abort-and-lifecycle.test.ts的其余用例干净且快速通过——在生效的地方，这次迁移确实消除了对模型的依赖。
问题 1 和 2 是我建议阻塞合并的两点，上述修复均已在真实运行中验证。如果方便，我可以直接提交这些修复。

Local verification of #7934 — real build, real CLI, no model credentialsI re-ran this migration locally before merging, to check that it delivers what it promises. Short version: it does — and I found two things I'd like tightened first. Setup. Worktree at PR head 1. The headline claim holds ✅
Sanity control: forcing the fake server to answer HTTP 500 makes the same tests fail (or hang in the CLI's retry/backoff), so they really are driving the CLI rather than passing down an empty path.
2. 🔴 The negative assertion is dead in four migrated tests (I'd fix this before merge)I planted four regressions in the built product and re-ran the migrated suite:
The coreTools miss is a scripting bug, not a product one. The same dead-assertion shape appears in four migrated tests (plus one that predates the PR):
One caveat on the fix: simply adding the fakeToolCall('list_directory', { path: testDir }, 'list-dir'),
// …
const blocked = findToolResults(messages, 'list_directory');
expect(blocked.length).toBeGreaterThan(0);
expect(blocked[0].isError).toBe(true);
expect(blocked[0].content).toContain('was declined');I ran that version both ways: green on a clean build, red the moment the coreTools allowlist check is removed. That is the property we want back. 3. 🟠 The abort tests cannot see a broken abortI severed abort completely — removed the The weak assertion predates the PR, but the migration is both what makes it cheap to fix and what removes the accidental safety net: with a real model a no-op abort burned wall clock and could trip the timeout; with a 30-chunk scripted reply, "abort late" and "abort now" are milliseconds apart. Worth bounding what arrives after the abort, e.g.: const before = messages.length;
controller.abort();
// …
expect(messages.length - before).toBeLessThan(10);4. 🟠
|
| before（main 的三个文件） | after（本 PR） | |
|---|---|---|
| 结果 | 33 失败 / 14 通过 | 47 全部通过（47） |
| 墙钟时间 | 309 秒 | 64 秒 |
连续 6 次运行，--retry=0 |
— | 每次都是 47/47（36–94 秒，波动来自我机器上的其他负载） |
所有出站代理指向死端口 127.0.0.1:9 |
— | 47/47 通过 |
反向对照：把 fake server 强行改成返回 HTTP 500 之后，这些测试就会失败（或者卡在 CLI 的重试退避里），说明它们确实在驱动真实 CLI，而不是在一条空路径上"假通过"。
e2e.yml 也没问题。我验证了命令行的 --exclude 是追加到配置里的 exclude 列表，而不是替换它（vitest list --filesOnly：64 → 62 个文件；terminal-bench、hook-integration、node_modules 和 loadtest 相关文件仍然被排除），所以新增的 --exclude '**/channel-plugin.test.ts' 只做了它该做的那一件事，新增的 nightly job 的路径也能正确匹配到该文件。
2. 🔴 四个被迁移用例里的反向断言已经失效（建议合并前修掉）
我在构建产物里植入了四个回归，然后重跑迁移后的测试集：
| 植入的回归 | 迁移后的测试集 |
|---|---|
getPermissionsDeny() → []（deny 规则失效） |
捕获 —— 8 个变红，其中 5 个是本次迁移的 |
CLI 忽略 SDK 的 canUseTool deny |
捕获 —— 3 个变红，其中 1 个是本次迁移的 |
关掉 PermissionManager.isToolEnabled() 里的 coreTools 白名单检查 |
漏掉 —— 30/30 依旧全绿 |
彻底切断 abort（Query 监听器 + transport 信号） |
漏掉 —— 16/16 依旧全绿 |
coreTools 这个漏检是脚本写法的问题，不是产品问题。should only allow specified tools when coreTools is set 断言的是 expect(toolNames).not.toContain('list_directory')，但它自己的 fake server 脚本只会发出 read_file 和 write_file —— list_directory 根本不会被请求，因此这个断言永远不可能失败。它在本 PR 的前两个提交里还是有效的；dc905ed（"trim fake server review assertions"）把 fakeToolCall('list_directory', …) 删掉了，却把断言留了下来。
同样的"死断言"形态出现在四个迁移用例里（另有一个是 PR 之前就存在的）：
| 用例 | 断言"不存在" | 它自己的脚本发出过吗？ |
|---|---|---|
| should only allow specified tools when coreTools is set | list_directory |
否 |
| should work with coreTools + allowedTools | run_shell_command |
否 |
| should work with coreTools + excludeTools | edit |
否 |
| should work with all three parameters together | edit |
否 |
| permissionMode plan should block all write tools…（PR 之前就有） | write_file |
否 |
修复方式上有一个坑：只是把 fakeToolCall 加回去是不行的。在脚本化的 server 下，被脚本发出的调用无论是否被允许执行，都会出现在 tool_use block 里，所以对工具调用做 not.toContain 即使在健康的构建上也会失败（我实测过）。断言必须移到工具的执行结果上：
fakeToolCall('list_directory', { path: testDir }, 'list-dir'),
// …
const blocked = findToolResults(messages, 'list_directory');
expect(blocked.length).toBeGreaterThan(0);
expect(blocked[0].isError).toBe(true);
expect(blocked[0].content).toContain('was declined');这个版本我两边都跑了：干净构建上是绿的，一旦把 coreTools 白名单检查去掉就立刻变红。这才是我们想要的性质。
3. 🟠 abort 相关用例看不见"abort 坏掉"
我把 abort 彻底切断 —— 既移除 Query 的 abort 监听器，又给 ProcessTransport 传了一个永远不会触发的 controller —— abort-and-lifecycle.test.ts 的 16 个用例依然全部通过。探针实验说明了原因：干净构建下，controller.abort() 之后数据流在 2 条消息内停止；abort 被切断后它会继续跑到 207 条消息才抛错。而这些用例断言的全部内容，只是"最终抛出了一个 AbortError"。
这个断言弱点在本 PR 之前就存在，但这次迁移既让它变得很容易修，也顺手拿掉了原本那层"意外的保险"：用真实模型时，abort 变成 no-op 会消耗大量墙钟时间、有可能触发超时；而换成 30 个 chunk 的脚本回复后，"晚一点 abort"和"立刻 abort"之间只差几毫秒。建议对 abort 之后还能收到多少内容加一个上界，例如：
const before = messages.length;
controller.abort();
// …
expect(messages.length - before).toBeLessThan(10);4. 🟠 用 requestIndex 编排脚本并不是自洽（hermetic）的
在我的开发机上（~/.qwen/memories/ 里有记忆），有五个用例稳定失败 —— 连续 4 次运行，每次都是同样这五个。其中四个是本 PR 迁移的：
原因是：记忆的 Auto-Recall 会在两轮对话之间额外发起一次非流式的 /chat/completions 调用。处理函数以 requestIndex 为键，于是这次 recall 调用吃掉了 index 1，真正的第二轮对话落到了默认分支 { content: 'Done.' } —— write_file 从未被请求，canUseTool 也从未被调用。list_directory.test.ts 的断言撞上的是同一件事：fakeServer.requests[1] 是 recall 调用，而不是携带工具结果的后续轮次。
把 QWEN_HOME 指到空目录后 47 个用例全部通过，所以 CI 会保持绿色 —— 但任何开启了记忆功能的贡献者都会看到五个红色用例，而且看不出原因。建议：处理函数改为按请求的形态分派，而不是按计数器 —— 例如只统计 body.stream === true 的请求，或者根据 messages 里是否已经出现 tool 角色的条目来分支；list_directory.test.ts 里也应该改成去查找那个携带工具结果的请求，而不是硬编码 [1]。
5. 附注（不是反对意见）
- 本 PR 的这些测试从未在它自己的 CI 里跑过。
e2e.yml的触发条件是push到main/feat/e2e/**、schedule和workflow_dispatch—— 没有pull_request触发，所以迁移后的测试集在合入之前是没有被验证的。建议合并前对test/fake-server-migration手动跑一次workflow_dispatch。（相关：e2e-test-linux上的if: github.event_name != 'pull_request' || …条件是死代码。） - PR 之前就存在，与本 PR 无关：
integration-tests/tsconfig.json在compilerOptions.paths内部放了一个"//"注释键，导致tsc -p integration-tests在检查任何东西之前就以TS5063挂掉；而且integration-tests不是 npm workspace，npm run typecheck --workspaces同样会跳过它。也就是说这些文件实际上从来没有被类型检查过。对三个改动文件跑eslint --max-warnings 0是干净的。
结论
方向是对的，数据也支持它：模型导致的 33 个失败 → 0，310 秒 → 64 秒，连续五次干净重跑，无网络依赖。我希望 §2 在合并前处理掉。在 main 上，提示词里写了"最后列一下目录"，模型通常真的会去调用那个应当被拦截的工具，所以那条分支是有真实（虽然是概率性的）覆盖的；迁移之后它的覆盖变成了零，但在文件里读起来仍然像是有覆盖。这是这次"用确定性换来的"唯一一处真实损失。§3 和 §4 可以作为后续跟进，不过 §4 在修掉之前会持续困扰贡献者。

1. Blocker — 808b2412 makes should throw AbortError with correct properties fail on a fast machine
808b2412 adds expect(false).toBe(true) after four abort loops. For the three content-driven cases that is fine. For should throw AbortError with correct properties it is not, because that case triggers its abort from a wall-clock timer:
setTimeout(() => controller.abort(), 1000);The fake server streams all 30 chunks with zero delay, so the query's duration is set by CLI startup, not by the model. Measured natural completion on this box: 730–2151 ms, the only variable being how loaded the machine is. Whenever it drops below 1000 ms the loop finishes first, the new guard throws, the catch swallows it, and isAbortError(AssertionError) fails — reported at line 653, which points away from the actual cause on line 650.
- 18 single-file runs at head: 8 under load → 0 failures; 10 idle → 2 failures, both in the runs where natural completion fell to 809 ms / 730 ms.
- Four failures across three independent campaigns — the 3-file confirmation run, idle runs 9–10, and the black-holed-proxy run. Always this one case.
retry: 2does not help. Re-running 5× at head with vitest's configured default on the idle box: 5/5 failed, all three attempts every time. The trigger is machine speed, not chance, so retries are fully correlated — this is not ordinary flake that a retry budget absorbs.
Worth saying plainly: 808b2412 is right that the case was passing vacuously — before it, the same race silently skipped every assertion. The problem is that it converts the vacuity into a failure instead of removing the race. (This also explains why this morning's 6 clean repeats did not see it: those runs were 36–94 s for the three files; mine entered the failing regime at 25–29 s.)
2. A verified fix — hold the fake response open
The helper already supports this — the handler type is FakeOpenAIResponse | Promise<FakeOpenAIResponse> and it is awaited (fake-openai-server.ts:124). No helper change needed:
// Hold the model response open so the 1000ms abort below lands inside the
// model request instead of racing CLI startup.
const fakeServer = await startFakeOpenAIServer(async () => {
await new Promise((resolve) => setTimeout(resolve, 5000));
return { contentChunks: LONG_CONTENT_CHUNKS };
}, FAKE_SERVER_OPTIONS);10/10 green in exactly the fast regime that broke head (natural completion 709–792 ms, i.e. below the 1000 ms timer), with no slowdown — the case still ends at ~1005 ms.
It also restores the coverage the case is named for, which connects to this morning's §3. A probe at head shows all three timer-based aborts firing before the fake server sees a single request (modelRequestsSeenByFakeServer=0, messages=0 for the 100 / 200 / 1000 ms timers) — they interrupt CLI process startup, not model streaming. With the fix, measured inside the catch: modelRequestsInFlightAtAbort=1. So the same edit that removes the race also puts the abort back where the test name claims it is, which is the precondition for the message-count bound suggested this morning to mean anything.
should handle abort immediately after query starts (200 ms) and should handle multiple abort calls gracefully (100/200/300 ms) are the same construction. Neither fails today (≈520–620 ms of margin), so I would not block on them, but they are worth the same treatment while you are in the file.
3. Round-3 §3 is closed — and the new assertion really can fail
With ls.ts mutated so every entry name is replaced by a marker (mutant verified live in dist/chunks/ls-X2ONIUMN.js):
- pre-fix oracle (
a26d1e5, asserts on the whole request body): passes — green on a tool that lists nothing. - head oracle (
5a711d5, asserts on therole:'tool'message): fails, with the mutant marker visible in the assertion'sReceivedvalue.
That last detail is the proof the narrowed oracle now reads the real tool result rather than the injected workspace listing. 5a711d5 is exactly the fix I proposed in round 3 and it works — this blocker is closed.
4. The coreTools hole, confirmed through a second oracle
Same image, lower panel. I planted the same regression this morning's report used — neutering the coreTools allowlist check in PermissionManager.isToolEnabled — and compared two versions of the test file on one build:
- head
tool-control.test.ts(helper removed indc905ed): 30/30 pass, regression invisible. bf928f22tool-control.test.ts(advertisedToolNames()still present): 3 failed | 27 passed, caught precisely at the threecoreToolssites.
One experiment, three conclusions: the mutant is live, the removed assertions were load-bearing, and the gap exists at head. My corrected vacuity scan also reproduces this morning's list exactly — 5 dead not.toContain assertions, 4 migrated plus the pre-existing write_file one.
On the fix, the two reports point at different remedies and I think both belong. This morning's is the more thorough one: move the assertion to the tool result (isError / 'was declined'), which proves the tool was actually blocked, and correctly notes that re-adding fakeToolCall alone fails even on a healthy build. What my run adds is that advertisedToolNames() is a cheaper and independent oracle that also catches this regression — it reads the tools array the CLI advertises to the model, so a tool wrongly registered shows up before it is ever called. Restoring those 11 lines and 4 call sites is a small change with measured value; the tool-result assertion is the deeper one. I would take both.
5. What works — plus one way to get real CI signal
Corroborating this morning's headline on a different machine, same bundled build for both columns:
merge-base 63166bd |
PR head 808b2412 |
|
|---|---|---|
| result, no credentials | 33 failed | 14 passed (47) | 47 passed (47) |

- Hermeticity: re-run with
HTTP(S)_PROXY=http://127.0.0.1:9→ 46 passed, 1 failed, and that one failure is the §1 timing blocker, not a network call. - Gates clean at head:

Beyond
e2e.ymlhaving nopull_requesttrigger: the only pre-merge lane that would runcli/list_directory.test.tsat all is the merge-queue-gatedintegration_clijob (ci.yml:691,if: github.event_name == 'merge_group') — and the newestmerge_grouprun in this repo is from 2026-07-02. So none of the three migrated files has pre-merge signal today. Usefully,e2e.ymldoes trigger on pushes tofeat/e2e/**— pushing this tree to such a branch gets a real full-suite run on exactly this commit, which is cheaper than aworkflow_dispatchagainst a branch the workflow will not pick up by ref.
Recommendation
Fix §1 with the §2 change (one test case, verified 10/10 here), take this morning's §2 fix for the dead coreTools assertion — optionally alongside restoring advertisedToolNames, which I measured as an effective second oracle — and this is merge-ready from my side. The migration is a clear win: 33 credential-induced failures → 0, 4.2× faster, hermetic under a black-holed proxy.
I pushed nothing to this branch; the fix above is a suggestion I validated locally, and my worktree is back at an unmodified 808b2412.

1. 阻塞项 —— 808b2412 让 should throw AbortError with correct properties 在快机器上失败
808b2412 在四个 abort 循环之后加了 expect(false).toBe(true)。对其中三个"由内容驱动"的用例没问题。但 should throw AbortError with correct properties 不行,因为它是靠墙上时钟定时器触发 abort 的:
setTimeout(() => controller.abort(), 1000);fake server 输出 30 个 chunk 时没有任何延迟,所以整个 query 的耗时由 CLI 启动决定,而不是由模型决定。我在这台机器上实测的自然完成时间是 730–2151 ms,唯一的变量就是机器有多忙。一旦它低于 1000 ms,循环就先结束了,新加的护栏抛出断言错误,被 catch 吞掉,然后 isAbortError(AssertionError) 失败 —— 报错位置是 653 行,而真正的原因在 650 行,指向是错的。
- head 上 18 次单文件运行:8 次带负载 → 0 失败;10 次空闲 → 2 次失败,两次的自然完成时间分别掉到 809 ms / 730 ms。
- 三个互相独立的批次里出现了 4 次失败 —— 三文件确认运行、空闲第 9/10 次、以及全出口黑洞代理那次。每次都是同一个用例。
retry: 2救不了。 用 vitest 配置里的这个默认值在空闲机器上重跑 5 次:5/5 失败,每次三个 attempt 全挂。触发条件是机器快慢而不是随机事件,所以重试之间完全相关 —— 这不是重试预算能吸收掉的普通 flake。
有一点值得说清楚:808b2412 判断"这个用例原来是空过的"是对的 —— 在它之前,同样的竞态只会静默跳过所有断言。问题在于它把"空过"变成了"失败",而没有消除竞态本身。(这也解释了为什么今早那 6 次干净重跑没有碰到它:那些运行三个文件耗时 36–94 秒,而我这边在 25–29 秒时就进入了会失败的区间。)
2. 已验证的修法 —— 把 fake 响应挂住
helper 本身已经支持:handler 的类型就是 FakeOpenAIResponse | Promise<FakeOpenAIResponse>,而且是 await 的(fake-openai-server.ts:124),不需要改 helper:
// Hold the model response open so the 1000ms abort below lands inside the
// model request instead of racing CLI startup.
const fakeServer = await startFakeOpenAIServer(async () => {
await new Promise((resolve) => setTimeout(resolve, 5000));
return { contentChunks: LONG_CONTENT_CHUNKS };
}, FAKE_SERVER_OPTIONS);在正是把 head 跑挂的那个"快"区间里(自然完成 709–792 ms,低于 1000 ms 定时器)10/10 全绿,而且不拖慢 —— 该用例仍然在约 1005 ms 结束。
它还顺带把这个用例名字所声称的覆盖面补了回来,这一点和今早的 §3 是连着的。head 上的探针显示,三个定时器 abort 全都在 fake server 收到任何请求之前就触发了(100 / 200 / 1000 ms 三档都是 modelRequestsSeenByFakeServer=0、messages=0)—— 它们中断的是 CLI 进程启动,而不是模型流式输出。加上修法后,在 catch 里实测:modelRequestsInFlightAtAbort=1。也就是说,同一处改动既消除了竞态,又把 abort 放回了用例名字所声称的位置 —— 而这正是今早建议的"限制 abort 之后还能收到多少条消息"那个断言能有意义的前提。
should handle abort immediately after query starts(200 ms)和 should handle multiple abort calls gracefully(100/200/300 ms)是同一种写法。它们今天还不会失败(还有约 520–620 ms 余量),所以我不会因为它们卡合并,但既然要改这个文件,顺手一起处理是值得的。
3. 第三轮 §3 已关闭 —— 新断言确实能失败
把 ls.ts 变异成"每个条目名都替换成一个 marker"(变异体已确认进入 dist/chunks/ls-X2ONIUMN.js):
- 修复前的断言(
a26d1e5,对整个请求体做匹配):通过 —— 工具什么都没列出来,它照样绿。 - head 的断言(
5a711d5,只对role:'tool'消息做匹配):失败,而且断言的Received值里能直接看到变异 marker。
最后这个细节本身就是证据:收窄后的断言现在读的是真正的工具结果,而不是注入的工作区目录结构。5a711d5 正是我第三轮提的那个修法,并且确实生效 —— 这个阻塞项可以关掉了。
4. coreTools 的盲区,用第二种断言口径再次确认
同一张图的下半部分。我植入了今早那份报告用的同一个回归 —— 把 PermissionManager.isToolEnabled 里的 coreTools 白名单判断废掉 —— 然后在同一个构建上对比了两个版本的测试文件:
- head 的
tool-control.test.ts(dc905ed删掉了 helper):30/30 全过,回归看不见。 bf928f22的tool-control.test.ts(advertisedToolNames()还在):3 失败 | 27 通过,而且恰好命中三个coreTools用例。
一个实验同时说明三件事:变异体是活的、被删掉的断言是有效的、这个盲区在 head 上确实存在。我修正后的失效断言扫描也与今早的清单完全一致 —— 5 条死掉的 not.toContain,其中 4 条是本次迁移的,加上 PR 之前就存在的那条 write_file。
关于修法,两份报告给出的方向不同,我认为两个都该要。 今早那份更彻底:把断言挪到工具的执行结果上(isError / 'was declined'),这样能证明工具确实被拦住了;而且它正确指出"只把 fakeToolCall 加回去"在健康构建上也会失败。我这次跑出来的补充结论是:advertisedToolNames() 是一个更便宜、且相互独立的断言口径,同样能抓到这个回归 —— 它读的是 CLI 广告给模型的 tools 数组,所以一个被错误注册的工具在被调用之前就会暴露。恢复那 11 行加 4 处调用是个很小的改动,而且价值是实测过的;工具结果断言则是更深的一层。两个我都会要。
5. 正常工作的部分 —— 外加一个拿到真实 CI 信号的办法
在另一台机器上复现今早的核心结论,两列用的是同一个打包构建:
merge-base 63166bd |
PR head 808b2412 |
|
|---|---|---|
| 无凭证时的结果 | 33 失败 | 14 通过 (47) | 47 通过 (47) |
| 耗时 | 308.07 s | 72.74 s |
- 密闭性:加上
HTTP(S)_PROXY=http://127.0.0.1:9重跑 → 46 通过、1 失败,而那唯一的失败就是 §1 的时序阻塞项,不是网络调用。 - head 上各项门禁干净:四个改动文件
prettier --check✓、eslint --max-warnings 0✓、scripts/tests/{e2e-workflow,package-scripts}.test.js16/16 ✓。 channel-plugin的排除是跑 vitest 验证的,不是读 YAML 猜的:带--exclude '**/channel-plugin.test.ts'→ 收集到 0 个用例;不带 → 3 个;nightly 任务的过滤条件 → 3 个。- CI 信号,比之前更具体一点。 除了
e2e.yml没有pull_request触发器之外:唯一可能在合并前跑到cli/list_directory.test.ts的通道,是只在合并队列里触发的integration_cli(ci.yml:691,if: github.event_name == 'merge_group')—— 而本仓库最近一次merge_group运行是 2026-07-02。所以这三个迁移文件今天都没有合并前信号。有用的是:e2e.yml确实会被推送到feat/e2e/**分支触发 —— 把这棵树推到这样一个分支,就能拿到针对这个 commit 的真实全量运行,比对一个该 workflow 按 ref 根本不会挑中的分支跑workflow_dispatch更省事。
建议
用 §2 的改法修掉 §1(只改一个用例,我这边验证了 10/10);采纳今早 §2 对失效 coreTools 断言的修法 —— 可以再顺带恢复 advertisedToolNames,我实测它是一个有效的第二道断言;这样在我这边就可以合并了。迁移本身是明确的收益:因凭证导致的 33 个失败 → 0,快 4.2 倍,在黑洞代理下依然密闭。
我没有往这个分支推任何改动 —— 上面的修法是我在本地验证过的建议,我的 worktree 已经还原回未改动的 808b2412。
Verified locally with Claude Code (Opus 5, 1M context) — real build + real bundled CLI + scripted fake OpenAI server; mutation/probe scripts and full logs available on request.
Third maintainer round mined for method (#7934 R4). The blocker it found had zero coverage in the skill — `timer`, `wall-clock`, `flake`, `retry`, `duration`, `deterministic` all returned 0, and the one `race` hit was a substring of "trace". - **Timing-triggered assertions have a threshold — measure it, do not sample it.** A new guard (`expect(false).toBe(true)` after an abort loop) turned a vacuous pass into a deterministic failure, because the case triggers its abort from `setTimeout(..., 1000)` while the query's duration is set by CLI startup rather than the server. Natural completion measured 730-2151 ms, so every box on the fast side of 1000 ms fails. The rule says to measure the operation's natural duration with the trigger disabled and compare it to the timer, because a green run only proves this box was slow enough. - **A speed-correlated failure is not flake, and a retry budget does not absorb it.** Random flake becomes a pass under `retry: 2`; this failed 5/5 runs on all three attempts. The two get opposite verdicts, so the kind has to be established before the verdict is written. Stated plainly in the skill: the verify job runs on a shared, loaded runner — the regime where such a test PASSES. Repetition cannot reproduce a fast-machine failure there; only computing the margin can. A rule that said "run it more times" would be useless in this lane. - **The failure one level before vacuity: the scenario never reached the code under test.** The vacuity check asks whether an assertion can fail; this asks whether the code ever ran. Four abort cases fired during CLI process startup, so the fake server saw zero requests and a suite named for mid-stream aborts never streamed — with every assertion green. Instrument the seam and assert the count is non-zero. Mutation-verified 5/5, each with landing proof against line-accurate anchors. 89/89 tests; prettier and eslint clean. Skill is 472 lines, up from 392.

Addressed both of today's verification reports in R4 §1/§2 (blocker — abort timer race): took the verified fix as-is — the fake server handler now holds the response open for 5s in Morning §2 + R4 §4 (dead coreTools assertions): took both remedies.

LGTM, looks ready to ship. ✅
…unds (QwenLM#8010) * feat(verify-pr): add four techniques from maintainer verification rounds Two hand-written maintainer rounds contained methods the skill could not have produced. Checked each against the current text before adding it; these four had no coverage at all. From QwenLM#7914 (live daemon A/B on the artifact-recording change): - Run every control on BOTH arms. That round's sharpest finding came from a control whose only job was to validate the BASE probe — "the empty list is a real absence, so have the model call record_artifact and watch an entry appear". Run on head as well, it showed the curated title being silently discarded. The control was not hunting for a bug; running it symmetrically is what found one. - A new writer into a shared store is an ordering change. The PR added write_file as a second writer into the artifact list; the bug was not in the new writer but in the collision, where a pre-existing first-writer-wins merge began discarding record_artifact's curated title and description while still reporting success. Enumerate the other writers, exercise the collision in both orders, and check what the loser is told — and separate the pre-existing cause from the PR's contribution so the author is not blamed for the policy. From QwenLM#7998 (ink cursor fix, real-terminal A/B): - When the oracle is an instrument, corroborate it with a mechanism that does not use that instrument. The hardware cursor row came from `tmux display-message -p '#{cursor_y}'`, then from a marker printed after the TUI exits — which lands wherever the cursor actually was. Two agreeing instruments turn a measurement into evidence; one tool's report about the system is not the system. - Re-run the generator on committed generated artifacts and diff. That round re-ran `npx patch-package ink` and found byte-different hunk headers, proving the .d.ts hunks were hand-written rather than regenerated as the description claimed. Also strengthens Not covered: proving a limitation is environmental requires an A/A control (boot base and head identically, show both fail the same way), because "seems environmental" and a real regression look identical in a report. Mutation-verified 4/4, each with landing proof. Two initially reported `landed: False` — the assertions match the whitespace-normalised text while the rules wrap across lines in the source, so the replace never fired and the green result proved nothing. Re-run against line-accurate anchors, both kill. 89/89 tests; prettier and eslint clean. * feat(verify-pr): teach the timing-race and scenario-arrival checks Third maintainer round mined for method (QwenLM#7934 R4). The blocker it found had zero coverage in the skill — `timer`, `wall-clock`, `flake`, `retry`, `duration`, `deterministic` all returned 0, and the one `race` hit was a substring of "trace". - **Timing-triggered assertions have a threshold — measure it, do not sample it.** A new guard (`expect(false).toBe(true)` after an abort loop) turned a vacuous pass into a deterministic failure, because the case triggers its abort from `setTimeout(..., 1000)` while the query's duration is set by CLI startup rather than the server. Natural completion measured 730-2151 ms, so every box on the fast side of 1000 ms fails. The rule says to measure the operation's natural duration with the trigger disabled and compare it to the timer, because a green run only proves this box was slow enough. - **A speed-correlated failure is not flake, and a retry budget does not absorb it.** Random flake becomes a pass under `retry: 2`; this failed 5/5 runs on all three attempts. The two get opposite verdicts, so the kind has to be established before the verdict is written. Stated plainly in the skill: the verify job runs on a shared, loaded runner — the regime where such a test PASSES. Repetition cannot reproduce a fast-machine failure there; only computing the margin can. A rule that said "run it more times" would be useless in this lane. - **The failure one level before vacuity: the scenario never reached the code under test.** The vacuity check asks whether an assertion can fail; this asks whether the code ever ran. Four abort cases fired during CLI process startup, so the fake server saw zero requests and a suite named for mid-stream aborts never streamed — with every assertion green. Instrument the seam and assert the count is non-zero. Mutation-verified 5/5, each with landing proof against line-accurate anchors. 89/89 tests; prettier and eslint clean. Skill is 472 lines, up from 392. * feat(verify-pr): six more techniques, from three maintainer rounds Mined QwenLM#7836 R2, QwenLM#7885 and QwenLM#7899 for method. Checked each candidate against the current text first; six had zero coverage, the rest were already there (harness teeth-checks, pin dereferencing, boundary probing, and the follow-up round's "re-measure, never diff"). The one that corrects the skill's own core method, from QwenLM#7836: - **Before calling a survivor vacuous, escalate to a finer mutation.** A whole-file revert is blunt enough to remove the PRECONDITION a test depends on, so a good test goes green because its scenario no longer occurs — from the outside, identical to a test that asserts nothing. A `finally`-cleanup test survived reverting four production files and died to deleting one line. Coarse survived + fine killed ⇒ the test is fine and the mutation was wrong. A false "your test is vacuous" costs the author more than a missed survivor does. From QwenLM#7836, the root cause shared by both of its blockers: - **When the same predicate is checked in two places, verify they see the same state.** A guard duplicated across a process boundary is two implementations of one question that diverge when their INPUTS differ. One settings key made a route ask sessionExistsInAnyState() with an unpinned runtime dir while the child asked with a pinned one, turning a clean 409 into a 500 plus a process.exit(1) that killed every session on the channel. Includes the temporal half: lazily-created backing files leave a window where a just-created entity is invisible to any on-disk existence check. - **Measure the blast radius on bystanders.** The caller's own error code understates a shared-state failure; the number that matters is an unrelated session going 200 -> 404 and a workspace list going 2 -> 0. From QwenLM#7885, which took a performance claim apart: - **Isolate the slice the mechanism can actually affect.** A speedup claim is two claims: the mechanism works, and the thing it speeds up matters. `--ignore-scripts` isolated what an npm download cache can touch — 36s of a 226s install — so the ceiling was 20s and the real saving 15%, not the claimed 75%. Then check it against the whole job: 33s off 14m37s. - **A mechanism that persists something has a cost — price it.** 219 MB per lockfile hash into a pool at 9.98 GB of a 10 GB cap, with 39 distinct lockfile states in 30 days: at the cap every entry evicts by LRU, including entries other jobs need and its own. - **Test the scarier consequences and report which do NOT hold.** The write-path finding was real; code injection was disproved (npm integrity-checks a tampered cache and refetches) and privilege escalation was disproved (chown -R does not follow symlinks). A finding that names what it is not is harder to wave away. - **Verify third-party actions from their own manifest.** The PR said the cache dir was discarded after the job; `action.yml` declares `post: dist/save/index.js` with `post-if: success()`, which uploads it as root with credentials intact — the opposite of the claim, and the whole finding. From QwenLM#7899: - **To exercise real production data safely, interpose a refusing proxy on the write path.** Wrap the client so every mutating call hard- fails, then run the shipped script verbatim: real counts, mechanical guarantee of no side effects. Mutation-verified 9/9, each with landing proof against line-accurate anchors. 89/89 tests; prettier and eslint clean. The skill is now 546 lines, up from 392 — the growth is deliberate and called out in the PR body's risk section. * feat(verify-pr): decomposed fixes, contextual limits, destination counts From QwenLM#7862 R4. Three additions, and a deliberate stop. - **When one fix bundles two changes, build the intermediate variants.** An A/B against base proves the pair works and says nothing about what each half does. That round compiled a third build with only the ordering change reverted, and the three-row table showed the halves do different jobs: moving `initialized = true` after the fallible work converts a 2,999-and-climbing backlog flood into a fail-safe retry, while `reduce()` restores liveness. Either alone leaves a channel that floods or wedges — a conclusion the two-cell A/B cannot reach. - **A limit measured in isolation does not transfer to the real call site.** The same `Math.max` spread threw between 110k and 130k elements inside a deep async stack, well below a standalone micro-benchmark. Bisect thresholds through the real code path and quote the harness; a limit taken from documentation or a toy loop is a guess about the system under test. - **Count at the destination, not at the component boundary.** The mirror of the scenario-arrival rule added earlier: envelopes the adapter emitted and prompts that reached the agent are different numbers, and every gate lives between them. A count taken at the seam can be right while the feature is silently dropped downstream. Declined from the same report, to protect prompt budget rather than because they are wrong: siblings-as-convention-oracle (the lockfile version table across five channels), degenerate fixtures that cannot distinguish two sort keys, and naming the condition under which a cosmetic finding becomes real. Each is a good technique; none is worth another rule competing for attention with the ones already here. The skill is now 578 lines, up from 392 on main (+47%) across this branch. That growth is the main risk on this PR and further additions should wait until a live round shows the current set changes behaviour. Mutation-verified 3/3 with landing proof. One mutation initially SURVIVED — it deleted text sitting AFTER the asserted phrase, so the assertion still matched and the green proved nothing; re-run against the phrase itself, it kills. 89/89 tests; prettier and eslint clean. * test(scripts): drop stale technique count from verify test name (QwenLM#8010) * fix(triage): correct verify-skill worked examples and verdict path (QwenLM#8010) Address review feedback on the verification-techniques skill: - Make the npm-cache worked example's numbers close: separate the 20 s download-slice ceiling (36 s to 16 s) from the 15% end-to-end saving (226 s to 193 s) rather than conflating them. - Stop overstating the tarball experiment: one tarball was poisoned, and the 2262-entry integrity coverage is a separate static fact. - Give the speed-correlated-failure rule a contract-legal verdict path by encoding the margin as a scripted assertion, and mark the load/idle sweep as the local-mode variant. - Fix the one bullet that broke its 2-space list continuation. - Pin the new contract-encoding clause in the workflow test. --------- Co-authored-by: wenshao <wenshao@example.com> Co-authored-by: qwen-code-dev-bot <qwen-code-dev@service.alibaba.com>

What this PR does
Migrates 39 real-model E2E test cases to use the deterministic
fake-openai-server, eliminating model output variance and inference latency as failure sources. These tests verify code logic (tool filtering, permission denial, abort mechanics, lifecycle management) through a non-deterministic channel (real model API) — the model is only needed to decide to call certain tools, not to produce specific content.Why it is needed
Over the past two weeks, 30 E2E CI runs failed on
main. The recurring failures concentrate intool-control.test.ts(7 failures),abort-and-lifecycle.test.ts(4 failures), andlist_directory.test.ts(2 failures). Each autofix attempt widened timeouts or relaxed assertions — treating symptoms while the root cause (coupling deterministic logic verification to non-deterministic model inference) persists. See #7616 for the full analysis.What changed
sdk-typescript/tool-control.test.tssdk-typescript/abort-and-lifecycle.test.tscli/list_directory.test.tsWhat is NOT changed
channel-plugin.test.ts(3 cases) stays on real model — it tests the full WebSocket → AcpBridge → model pipeline end-to-end and belongs in the nightly smoke layer.cli/qwen-serve-routes.test.ts(35 cases) is already model-free — no migration needed.Reviewer Test Plan
How to verify
Run the migrated tests locally without a model API key:
All tests should pass deterministically in < 2s per case (no real model calls).
Closes #7616
