feat(channels): support webhook-triggered channel tasks - #6495
Conversation

Re-run at commit Template: complete ✓ — all required headings present with bilingual body, reviewer test plan, risk/scope, and tested-on table. Problem: real and well-scoped. Daemon-managed channels today respond to inbound chat messages and scheduled loops, but external systems (CI, monitoring, deployment webhooks) have no authenticated path to trigger a channel workflow. This is an observed gap, not theoretical hardening. Direction: aligned with qwen-code's daemon/channel architecture. Channels are designed for unattended agent execution; adding an HTTP-triggered entry point is a natural extension. No direct CHANGELOG reference, but the channel adapter system and daemon serve model are established patterns this builds on. Size:
Cross-package: channels/base, cli (serve + commands/channel), acp-bridge, sdk-typescript. The acp-bridge changes (~456 production lines) add Approach: the scope feels right for the feature. Webhook entry → config parsing → IPC to worker → agent prompt → proactive delivery is the minimum viable chain. Each link is implemented. No unrelated refactors or scope creep spotted. The security model (shared-secret auth before bearer, timing-safe comparison, prototype pollution guards, depth limits, rate limiting) is thoughtful. CI status: Test (ubuntu) ✅, review-pr ✅, precheck ✅, web-shell E2E ✅. All green. Moving to code review. 🔍 中文说明重新运行于 commit 模板：完整 ✓ — 所有必需标题齐全，含双语正文、Reviewer Test Plan、Risk/Scope 和测试平台表格。 问题：真实且有明确范围。当前 daemon-managed channel 只能响应群消息和定时 loop，外部系统（CI、监控、发布 webhook）没有经过鉴权的触发路径。这是已观测到的功能缺口，不是理论性加固。 方向：与 qwen-code 的 daemon/channel 架构对齐。Channel 本身为无人值守 agent 执行设计，增加 HTTP 触发入口是自然扩展。CHANGELOG 无直接参考，但 channel adapter 系统和 daemon serve 模型是此功能依托的已有模式。 规模：
跨包：channels/base、cli（serve + commands/channel）、acp-bridge、sdk-typescript。acp-bridge 变更（~456 行生产代码）新增 方案：范围合理。Webhook 入口 → 配置解析 → IPC 到 worker → agent prompt → 主动发送是最小可行链路，每个环节均已实现。未发现无关重构或范围蔓延。安全模型（bearer 之前的 shared-secret 鉴权、timing-safe 比较、原型污染防护、深度限制、速率限制）设计周全。 CI 状态：Test (ubuntu) ✅、review-pr ✅、precheck ✅、web-shell E2E ✅。全部通过。 进入代码审查 🔍 — Qwen Code · qwen3.7-max |

Re-run at commit Stepping back: this PR does what it says — adds webhook-triggered channel tasks to the daemon. The motivation is real (external systems can't trigger channel workflows today), the implementation is thorough (auth, IPC, prompt safety, proactive delivery, graceful shutdown), and the test coverage is extensive (~3,050 lines of tests for ~2,962 lines of production code). The security model is well-considered for an unattended execution path: shared-secret auth before bearer, timing-safe comparison, input sanitization, prototype pollution guards, depth limits, rate limiting at both pre-auth and post-auth layers. The prompt explicitly tells the agent that webhook data is untrusted and must not be followed as instructions — good defense-in-depth against prompt injection. The code reuses existing patterns (session queues, generation tracking, proactive send, daemon worker infrastructure) rather than inventing new abstractions. The The size is large (~2,962 production lines across 4 packages) but every part maps to a necessary component of the feature. No scope creep, no drive-by refactors. My independent proposal from Stage 2 was matched or exceeded — particularly the security hardening (SHA-256 digest comparison, iterative depth check) which goes beyond what I would have implemented. The lingering Approval guardrail check: this is a cross-repository Verdict: this is ready to merge. The implementation is solid, the security is thoughtful, CI is green, and the feature fills a real gap in the channel system. 中文说明重新运行于 commit 退一步看：这个 PR 做了它声称的事情 — 为 daemon 添加 webhook 触发的 channel 任务。动机真实（外部系统今天无法触发 channel workflow），实现周全（鉴权、IPC、prompt 安全、主动投递、优雅关闭），测试覆盖广泛（~3,050 行测试对应 ~2,962 行生产代码）。 安全模型对无人值守执行路径考虑充分：bearer 之前的 shared-secret 鉴权、timing-safe 比较、输入消毒、原型污染防护、深度限制、预鉴权和后鉴权层的速率限制。Prompt 明确告诉 agent webhook 数据是不可信的，不能作为指令执行 — 对 prompt injection 的纵深防御良好。 代码复用了已有模式（session queue、generation tracking、proactive send、daemon worker 基础设施），而非发明新抽象。 规模较大（~2,962 行生产代码跨 4 个包），但每个部分都对应功能的必要组件。无范围蔓延，无顺手重构。 Stage 2 的独立提案被匹配或超越 — 特别是安全加固（SHA-256 摘要比较、迭代深度检查）超出了我会实现的水平。 遗留的 审批护栏检查：这是跨仓库 结论：可以合并。实现扎实，安全性考虑周全，CI 通过，功能填补了 channel 系统的真实缺口。 — Qwen Code · qwen3.7-max |

The webhook implementation is solid — security, integration, and tests are all well done. However, this PR bundles an unrelated A2A feature (packages/cli/src/serve/a2a/, a2a settings in settingsSchema.ts) and commits AI agent working artifacts (docs/superpowers/). Please split the A2A module into a separate PR and remove the agent working documents before merge. See triage comments above for details. 🙏

[Critical] parseChannelWebhookConfig throws on malformed input (e.g. webhooks: "invalid", missing chatId, bad secretEnv), and this call has no try/catch. Because loadServeChannelWebhookConfigs runs during createServeApp, a typo in one channel's webhooks config crashes the entire daemon HTTP server — not just webhook routes, but health checks, sessions, prompts, and all other endpoints.

[Critical] Webhook routes are registered AFTER app.use(bearerAuth(opts.token)) at line 704. External CI systems (GitHub Actions, Jenkins) can only send a URL + secret header — they cannot provide a Qwen daemon admin bearer token. To use webhooks, operators must share the full daemon token with CI runners, granting access to sessions, file writes, settings, and all other daemon operations. The webhook secret was designed as independent, lower-privilege auth but is unreachable without the bearer token. The route tests (channel-webhooks.test.ts) register the route on a bare Express app without bearerAuth, so this conflict is never detected.
Suggested fix: move registerChannelWebhookRoutes to the pre-auth section (before app.use(bearerAuth(...)), after installJsonBodyParser), relying solely on the webhook secret for authentication.

[Critical] parseWebhookSource (in config-utils.ts) allows sources without a secret — it returns { targets } with no secret key when none is configured. But this route check (typeof secret !== 'string') then unconditionally returns 401, making secretless sources permanently unreachable. The 401 is indistinguishable from a wrong secret, so an operator who misconfigured (or forgot) the secret sees the same error as someone who sent the wrong value.
Suggested fix: reject secretless sources at config-parse time with a clear error (e.g. "Channel '${name}' webhook source must have 'secret' or 'secretEnv'"), so the error surfaces at startup instead of silently at request time.

[Critical] The prompt inserts webhook event data (title, summary, payload) from an external HTTP POST without instructing the model to treat it as untrusted input. The sanitization functions prevent structural attacks (tag forgery, control characters) but do not guard against natural-language prompt injection. A webhook sender that knows the shared secret — or a legitimate sender forwarding user-generated content like a GitHub issue comment containing "ignore all previous instructions" — can manipulate the agent's behavior. With yolo approval mode, a successful injection could trigger arbitrary tool calls.

[Critical] When Node.js IPC send fails (e.g., pipe closed, channel disconnected), the callback receives a plain Error from Node.js — not a ChannelWebhookEnqueueError. Downstream, classifyChannelWebhookEnqueueError checks isChannelWebhookEnqueueError(error) which requires either instanceof ChannelWebhookEnqueueError or a duck-typed {code, message} shape. A plain Error matches neither, so it falls to the catch-all returning HTTP 500 with the raw Node.js error message in the response detail field, instead of the correct 503 with code channel_worker_unavailable.

| # | Change | Verdict |
|---|---|---|
| 1 | channel-worker-supervisor.ts: wrap IPC send failures in ChannelWebhookEnqueueError('channel_worker_unavailable') |
✅ Load-bearing. Reproduced the pre-fix bug and its absence after. |
| 2 | routes/channel-webhooks.ts: drop detail from the 500 fallback |
✅ Confirmed. Internal messages no longer reach the caller. |
| 3 | config-utils.ts + server.ts: parseChannelWebhookConfigLenient |
|
| 4 | daemon-worker.ts: try/catch around process.send for task results |
✅ Benign hardening; covered by the new unit test. Not observable at the HTTP layer — the worker exits within 1 s of the daemon dying, no orphan. |
1 + 2. The IPC-failure fix is real (A/B)
I fired 60 concurrent authenticated webhook POSTs and SIGKILLed the channel worker 50 ms in, so some sends were already queued on the IPC channel when it died. That hits both rewritten branches: the synchronous send.call(...) throw and its async error callback.
Pre-fix (60a1b7b2) those requests came back as:
500 {"error":"Failed to enqueue channel webhook task","code":"channel_webhook_enqueue_failed","detail":"write EPIPE"}
500 {"error":"Failed to enqueue channel webhook task","code":"channel_webhook_enqueue_failed","detail":"Channel closed"}
— a 500 for a plainly retryable condition, with the raw Node error text echoed to the caller. Post-fix the same probe produced zero 500s across four runs; every IPC failure became 503 channel_worker_unavailable with no detail. Both branches of the rewrite reproduce (write EPIPE is the callback path, Channel closed is the synchronous throw). This is a genuine fix and it is correctly classified.
3. The lenient webhook-source parser is inert
The commit adds parseChannelWebhookConfigLenient so that one malformed source no longer disables a channel's other webhook sources, and server.test.ts adds "keeps valid webhook sources when a sibling source is malformed" to lock it in.
That test builds the app with createServeApp({...}, undefined, { bridge: fakeBridge(), enqueueChannelWebhookTask }). There is no channel worker in it. And the channel worker is precisely what still parses strictly:
// packages/cli/src/commands/channel/config-utils.ts:467 (parseChannelConfig)
webhooks: parseWebhookConfig(name, rawConfig), // <- strict, unchangedparseConfiguredChannels() rethrows anything parseChannelConfig throws, so the worker dies before ready, and qwen serve follows it down. I configured channels.sinkchan.webhooks.sources = { ci: <valid>, jenkins: <secretEnv unset> } — the PR's own test fixture, verbatim — and started qwen serve --channel sinkchan, i.e. the deployment this change exists to protect:
[daemon] Skipping malformed webhook source "jenkins" for channel "sinkchan": ... references an unset environment variable.
[Channel] daemon worker failed: Error in channel "sinkchan": ... references an unset environment variable.
qwen serve: runtime startup failed: Channel worker exited before ready (code=1, signal=null).
The daemon binds :4170, answers /health for about a second, then exits. Pre-fix and post-fix are byte-for-byte the same outcome; only the log wording differs. Under systemd or Docker this is a restart loop either way.
I looked for any configuration in which the lenient parser lets a webhook actually run, and there isn't one:
| Deployment | Pre-fix | Post-fix | Delivered? |
|---|---|---|---|
--channel sinkchan (channel is hosted) |
daemon exits | daemon exits | no, either way |
--channel cleanchan (malformed channel not hosted) |
401 |
503 channel_worker_unavailable |
no |
no --channel at all |
401 |
500 channel_webhook_enqueue_failed |
no |
So the change only ever swaps one rejection for another, and in the no---channel row it swaps a 401 for a 500.
The fix that would make the commit message true is to use the lenient parser in parseChannelConfig as well. I tried it — one call site — and the motivating scenario then works end to end: the worker boots, logs [Channel] Skipping malformed webhook source "jenkins", "sinkchan" connected., and POST /channels/sinkchan/webhooks/ci returns 202 and delivers through pushProactive.
It is not free, though: 8 tests in config-utils.test.ts (rejects webhook sources without a secret, rejects webhook sources with both secret and secretEnv, rejects webhook targets without chatId or senderId, …) assert that parseChannelConfig throws on exactly these inputs. So this is a policy decision — fail loudly at startup, or degrade gracefully — not a blind one-liner. Whichever you pick, please make the HTTP loader and the worker agree. Shipping a loader that accepts config the worker will reject is the worst of both.
4. A leftover strict/lenient split inside one boot
readDeferredWebhookSecret in run-qwen-serve.ts:1471 still calls the strict parseChannelWebhookConfig, while the in-route loader now calls the lenient one. The triage bot flagged this; it is real and reachable. With the bad-sibling config and no --channel (so the serve fast path sets deferRuntimeUntilFirstHealth), the same URL with the same valid secret gets two different answers depending on whether the runtime has booted yet:
EARLY (deferred gate, strict): 401 {"error":"Invalid webhook secret"}
LATE (in-route gate, lenient): 500 {"error":"Failed to enqueue channel webhook task", ...}
[webhook-secret] failed to read deferred webhook secret for sinkchan/ci:
Channel "sinkchan" field "webhooks.sources.jenkins.secretEnv" references an unset environment variable.
The 401 is actively misleading — the secret was correct; a sibling source was malformed.
No regressions
The documented status matrix still holds exactly, against the live daemon at head. 14/14.
The happy path is unchanged: 202, the agent runs unattended, and the final response is delivered proactively to the configured target with isGroup preserved. The prompt on the wire still carries the channel instructions, the [External event ...] header, the unattended-execution framing and the untrusted-data guard, in that order.
Suites at head, all green — 1820 tests — plus npm run typecheck clean (worth running: CI does not gate on tsc):
packages/channels/base ChannelBase + SessionRouter + DaemonChannelBridge 466 passed
packages/cli config-utils + daemon-worker + channel-worker-
supervisor + routes/channel-webhooks 189 passed
packages/cli server.test.ts + run-qwen-serve.test.ts 796 passed

Carried-over findings — status at head
From my eecb60c36 report |
Status at 43cd2b88 |
|---|---|
1. MAX_ACTIVE_WEBHOOK_TASKS is worker-global; one channel starves the rest |
Open. Re-reproduced: 16 slow tasks on sinkchan → a webhook to a completely idle second channel returns 503 channel_webhook_queue_full. |
2. approvalMode only takes effect when webhooks is configured |
Open. Gate is byte-identical. |
3. 413 advertises max 10 MB but the route limit is 1mb |
Open. Reproduced live. |
4. No---channel daemon returns 500 + leaks the internal message |
Half fixed. The detail leak is gone (change 2). The status is still 500 channel_webhook_enqueue_failed, where your own contract says 503 channel_worker_unavailable — and the worker's own Channel "X" is not running. does map to 503. Same condition, two statuses. createDisabledChannelWorkerSupervisor() should throw ChannelWebhookEnqueueError('channel_worker_unavailable', ...). |
5. JSON.stringify(payload, null, 2) is thrown away by sanitizePromptText |
Open. Confirmed on the wire: the model sees { "repo": "acme/app", "branch": "main" }, and the indentation is charged against the 6000-char payload budget. |
6. createDeferredChannelWebhookAuth looks unreachable in production |
Confirmed and sharpened. With --channel: 5 in-route auth failures, 0 deferred. Without --channel (fast path): 0 in-route, 1 deferred. So the deferred gate only ever runs when there is no worker — i.e. when the request it authenticates is guaranteed to hit finding 4's 500. |
Recommendation
Changes 1, 2 and 4 in 43cd2b886 are good — merge them. Change 3 should not ship as-is: it makes the HTTP layer accept configuration that the worker refuses to boot with, and its test cannot catch that because it never starts a worker. Either finish it (lenient in parseChannelConfig too, and update the 8 strictness tests), or revert it and keep the strict behaviour, which at least fails loudly and consistently. I'd also fix finding 4's status code and the readDeferredWebhookSecret strict/lenient split at the same time, since all three are the same underlying question: what is the contract when a channel's webhook config is partially broken?
Nothing here blocks the feature itself — the webhook path works, is correctly authenticated, correctly bounded, and correctly unattended.
Harness
The only thing I supplied is a test-only channel adapter ("sink") that extends the real ChannelBase, mirrors TelegramChannel's proactive-send surface (supportsProactiveSend, numeric-only supportsProactiveTarget, pushProactive), and appends every outbound send to a JSONL file. It is loaded through the production extension path — $QWEN_HOME/extensions/<ext>/qwen-extension.json → loadChannelsFromExtensions() → registerPlugin() — so daemon-worker.ts, ChannelBase.runWebhookTask, SessionRouter, DaemonChannelBridge, channel-worker-supervisor.ts and routes/channel-webhooks.ts all run unmodified. Only the outbound chat transport is a local sink instead of DingTalk/Telegram, and the model endpoint is a local mock that records every request.
A/B was done by checking out the five non-test files of 43cd2b886 at its parent 60a1b7b2, rebuilding, and caching both packages/cli/dist trees so the identical probe could be replayed against each. Both dists were fingerprinted before every run (parseChannelWebhookConfigLenient, Channel worker IPC send failed:).

在 head 43cd2b88 上的复验
我上一份报告验证的是 eecb60c36。此后这个分支合并了三次 main，外加恰好一个行为变更提交 —— 43cd2b886（"fix(channels): harden webhook enqueue failures"）。我把分支构建成真实的 dist 产物，针对真实的 qwen serve daemon、真实的 channel worker 子进程、真实的 ACP agent 子进程以及本地 mock OpenAI 端点重跑了整套装置。被测代码没有任何 mock。 下面每一条结论，我都同时构建了父提交 60a1b7b2 并跑了完全相同的探针，所以每个判断都是 A/B 对照，而不是单侧观察。
结论：43cd2b886 的四处改动里，两处是真正的修复，我希望它们合入。但其中一处 —— 宽松的 webhook source 解析 —— 并没有做到它的 commit message 和测试所声称的事：在它本该保护的那种部署形态下，它是完全无效的。 我上一份报告里的所有内容仍然可复现，没有任何回归。
43cd2b886 改了什么，以及是否生效
| # | 改动 | 结论 |
|---|---|---|
| 1 | channel-worker-supervisor.ts：把 IPC send 失败包装成 ChannelWebhookEnqueueError('channel_worker_unavailable') |
✅ 真正起作用。 我复现了修复前的 bug，也复现了修复后它的消失。 |
| 2 | routes/channel-webhooks.ts：500 兜底分支去掉 detail |
✅ 已确认。 内部错误信息不再回显给调用方。 |
| 3 | config-utils.ts + server.ts：parseChannelWebhookConfigLenient |
|
| 4 | daemon-worker.ts：给发送任务结果的 process.send 加 try/catch |
✅ 良性加固；新增的单测已覆盖。在 HTTP 层观察不到 —— daemon 死后 worker 会在 1 秒内退出，没有孤儿进程。 |
1 + 2. IPC 失败的修复是真的（A/B）
我并发发出 60 个已鉴权的 webhook POST，并在 50 ms 后 SIGKILL channel worker，这样有些消息在 IPC 通道关闭时已经排在队列里了。这会同时命中被重写的两条分支：send.call(...) 的同步抛出，以及它的异步错误回调。
修复前（60a1b7b2），这些请求返回：
500 {"error":"Failed to enqueue channel webhook task","code":"channel_webhook_enqueue_failed","detail":"write EPIPE"}
500 {"error":"Failed to enqueue channel webhook task","code":"channel_webhook_enqueue_failed","detail":"Channel closed"}
—— 一个明显可重试的状况却返回 500，并且把 Node 的原始错误文本回显给了调用方。修复后，同一个探针跑了四轮，零个 500；每一个 IPC 失败都变成了 503 channel_worker_unavailable，且不带 detail。两条分支都复现了（write EPIPE 是回调路径，Channel closed 是同步抛出路径）。这是一个货真价实的修复，分类也是正确的。
3. 宽松的 webhook source 解析是无效的
该提交新增了 parseChannelWebhookConfigLenient，让单个畸形 source 不再连累同一 channel 的其他 webhook source；server.test.ts 也新增了 "keeps valid webhook sources when a sibling source is malformed" 来锁定这个行为。
但那个测试是用 createServeApp({...}, undefined, { bridge: fakeBridge(), enqueueChannelWebhookTask }) 构建的，里面根本没有 channel worker。而恰恰是 channel worker 仍然在严格解析：
// packages/cli/src/commands/channel/config-utils.ts:467 (parseChannelConfig)
webhooks: parseWebhookConfig(name, rawConfig), // <- 严格，未改动parseConfiguredChannels() 会把 parseChannelConfig 抛出的任何错误重新抛出，于是 worker 在 ready 之前就死了，qwen serve 也随之退出。我按照该 PR 自己的测试夹具原样配置了 channels.sinkchan.webhooks.sources = { ci: <合法>, jenkins: <secretEnv 未设置> }，然后以 qwen serve --channel sinkchan 启动 —— 也就是这个改动本该保护的那种部署：
[daemon] Skipping malformed webhook source "jenkins" for channel "sinkchan": ... references an unset environment variable.
[Channel] daemon worker failed: Error in channel "sinkchan": ... references an unset environment variable.
qwen serve: runtime startup failed: Channel worker exited before ready (code=1, signal=null).
daemon 会绑定 :4170，对 /health 应答大约一秒，然后退出。修复前与修复后逐字节完全相同，只有日志措辞不一样。在 systemd 或 Docker 下，两种情况都是重启循环。
我尝试寻找任何一种「宽松解析能让 webhook 真正跑起来」的配置，结果一个都没有：
| 部署形态 | 修复前 | 修复后 | 是否投递成功？ |
|---|---|---|---|
--channel sinkchan（worker 承载该 channel） |
daemon 退出 | daemon 退出 | 都不会 |
--channel cleanchan（畸形 channel 未被承载） |
401 |
503 channel_worker_unavailable |
否 |
完全不带 --channel |
401 |
500 channel_webhook_enqueue_failed |

所以这个改动只是把一种拒绝换成了另一种拒绝；而在「不带 --channel」那一行，它把 401 换成了 500。
能让 commit message 成立的修复，是让 parseChannelConfig 也用宽松解析器。我试过了 —— 只改一处调用点 —— 那个动机场景就真的端到端跑通了：worker 正常启动，打印 [Channel] Skipping malformed webhook source "jenkins"、"sinkchan" connected.，POST /channels/sinkchan/webhooks/ci 返回 202 并通过 pushProactive 成功投递。
不过这不是免费的：config-utils.test.ts 里有 8 个测试（rejects webhook sources without a secret、rejects webhook sources with both secret and secretEnv、rejects webhook targets without chatId or senderId 等）断言 parseChannelConfig 在这些输入下必须抛错。所以这是一个策略选择 —— 启动即大声失败，还是优雅降级 —— 而不是一个可以闭眼改的一行。无论你选哪个，请让 HTTP 加载器和 worker 保持一致。让加载器接受一份 worker 拒绝启动的配置，是两者中最糟的组合。
4. 同一次启动内残留的严格/宽松分裂
run-qwen-serve.ts:1471 的 readDeferredWebhookSecret 仍然调用严格的 parseChannelWebhookConfig，而路由内的加载器现在用的是宽松版。triage bot 标出了这一点；它是真实且可达的。在 bad-sibling 配置且不带 --channel 时（serve fast path 会设置 deferRuntimeUntilFirstHealth），同一个 URL、同一个正确的 secret，会因为 runtime 是否已启动而得到两种不同的答案：
EARLY (deferred 门控, 严格): 401 {"error":"Invalid webhook secret"}
LATE (路由内门控, 宽松): 500 {"error":"Failed to enqueue channel webhook task", ...}
[webhook-secret] failed to read deferred webhook secret for sinkchan/ci:
Channel "sinkchan" field "webhooks.sources.jenkins.secretEnv" references an unset environment variable.
这个 401 有很强的误导性 —— secret 是对的，出问题的是同级的另一个 source。
无回归
文档化的状态码矩阵在 head 的实时 daemon 上完全成立，14/14。
正常路径未变：202，agent 无人值守执行，最终响应被主动投递到配置的 target，且 isGroup 得以保留。抓到的发往模型的 prompt 依然依次包含 channel instructions、[External event ...] 头部、无人值守执行说明、以及不可信数据防护语句。
head 上的测试套件全部通过 —— 1820 个测试 —— 另外 npm run typecheck 也是干净的（值得一跑：CI 并不用 tsc 把关）：
packages/channels/base ChannelBase + SessionRouter + DaemonChannelBridge 466 passed
packages/cli config-utils + daemon-worker + channel-worker-
supervisor + routes/channel-webhooks 189 passed
packages/cli server.test.ts + run-qwen-serve.test.ts 796 passed
packages/acp-bridge bridge.test.ts 369 passed
历史发现在 head 上的状态
我在 eecb60c36 报告中的发现 |
在 43cd2b88 上的状态 |
|---|---|
1. MAX_ACTIVE_WEBHOOK_TASKS 是 worker 全局的，一个 channel 会饿死其他所有 channel |
仍存在。 已再次复现：向 sinkchan 发 16 个慢任务后，向一个完全空闲的第二个 channel 发 webhook，返回 503 channel_webhook_queue_full。 |
2. approvalMode 只有配置了 webhooks 时才生效 |
仍存在。 门控代码逐字节未变。 |
3. 413 提示 max 10 MB，但路由实际限制是 1mb |
仍存在。 已实测复现。 |
4. 不带 --channel 的 daemon 返回 500 并泄漏内部信息 |
修了一半。 detail 泄漏已消失（改动 2）。状态码仍是 500 channel_webhook_enqueue_failed，而你们自己的契约写的是 503 channel_worker_unavailable —— 并且 worker 自己抛的 Channel "X" is not running. 确实映射为 503。同一个语义条件，两个状态码。createDisabledChannelWorkerSupervisor() 应该抛 ChannelWebhookEnqueueError('channel_worker_unavailable', ...)。 |
5. JSON.stringify(payload, null, 2) 的格式化被 sanitizePromptText 丢弃 |
仍存在。 已在链路上确认：模型收到的是 { "repo": "acme/app", "branch": "main" }，而那些缩进还要占用 6000 字符的 payload 预算。 |
6. createDeferredChannelWebhookAuth 在生产中似乎不可达 |
已确认并进一步收敛。 带 --channel 时：5 条路由内鉴权失败，0 条 deferred。不带 --channel（fast path）时：0 条路由内，1 条 deferred。也就是说 deferred 门控只在没有 worker 时才会运行 —— 而它放行的请求，必然会撞上发现 4 的那个 500。 |
建议
43cd2b886 中的改动 1、2、4 都很好，建议合入。改动 3 不应以现状合入：它让 HTTP 层接受了一份 worker 根本无法据以启动的配置，而它的测试之所以发现不了，是因为那个测试从不启动 worker。要么把它做完（parseChannelConfig 也改用宽松解析，并同步更新那 8 个严格性测试），要么回退它、保留严格行为 —— 严格至少会大声且一致地失败。我建议顺带一起修掉发现 4 的状态码和 readDeferredWebhookSecret 的严格/宽松分裂，因为这三者本质上是同一个问题：当某个 channel 的 webhook 配置部分损坏时，契约到底是什么？
这里没有任何一条阻塞这个特性本身 —— webhook 路径是能工作的，鉴权正确、边界正确、无人值守语义也正确。
测试脚手架
我唯一自己提供的是一个仅用于测试的 channel adapter（"sink"）：它继承真实的 ChannelBase，复刻了 TelegramChannel 的主动发送接口（supportsProactiveSend、只接受数字 threadId 的 supportsProactiveTarget、pushProactive），并把每一次外发追加写入 JSONL 文件。它通过生产环境的 extension 路径加载 —— $QWEN_HOME/extensions/<ext>/qwen-extension.json → loadChannelsFromExtensions() → registerPlugin() —— 所以 daemon-worker.ts、ChannelBase.runWebhookTask、SessionRouter、DaemonChannelBridge、channel-worker-supervisor.ts 和 routes/channel-webhooks.ts 全部按原样运行。只有最终外发的聊天通道被换成了本地文件 sink，模型端点则是一个会记录每个请求的本地 mock。
A/B 的做法是：把 43cd2b886 的五个非测试文件检出到其父提交 60a1b7b2，重新构建，并把两份 packages/cli/dist 都缓存下来，以便对同一个探针重放。每次运行前都会对 dist 做指纹校验（parseChannelWebhookConfigLenient、Channel worker IPC send failed:）。

What this PR does
Adds webhook-triggered tasks for daemon-managed channels. A configured external webhook source can POST an event to
qwen serve; Qwen receives the event as context, generates a response, and the channel worker proactively delivers that generated response to the configured chat target.The implementation covers webhook task modeling, prompt construction, unattended channel execution, channel config parsing, worker IPC, HTTP route handling, security hardening, and user/developer documentation.
Why it's needed
Channels currently respond to inbound chat messages and scheduled loop prompts, but external systems cannot trigger a channel workflow directly. This enables integrations such as CI, monitoring, and deployment webhooks while keeping the behavior agentic: Qwen summarizes and judges the event instead of blindly relaying raw notifications.
Reviewer Test Plan
How to verify
Configure a daemon-managed channel with
approvalMode: "yolo", a webhook source secret, and a configured target. Startqwen serve, POST to/channels/:channelName/webhooks/:sourcewithx-qwen-webhook-secret, and confirm the route returns202after the worker accepts the task. Confirm invalid secrets return401, unknown target refs return404, worker unavailable errors return503, IPC timeout returns504, and accepted tasks deliver Qwen's final response through proactive channel send.Local verification already run:
Expected results: base channel tests pass, CLI focused tests pass, build passes, and typecheck passes.
Evidence (Before & After)
Before: daemon-managed channels had no authenticated HTTP webhook path for external systems to trigger agent-generated proactive channel messages.
After:
qwen servecan authenticate a configured webhook source, enqueue the task through the channel worker, run Qwen with channel instructions/boundary context, and proactively deliver the generated response to the configured target.Tested on
Environment (optional)
Local workspace on macOS with Node/npm repo scripts.

中文说明
这个 PR 做了什么
为 daemon 管理的 channel 增加 webhook 触发任务能力。外部系统可以向
qwen serve的配置化 webhook source POST 事件；Qwen 会把事件作为上下文理解、总结和判断，然后由 channel worker 将生成结果主动发送到配置的群目标。实现包含 webhook task 建模、prompt 构造、无人值守 channel 执行、channel 配置解析、worker IPC、HTTP route、安全加固，以及用户和开发者文档。
为什么需要
现有 channel 可以响应群消息和定时 loop prompt，但外部系统不能直接触发 channel workflow。这个能力可以接入 CI、监控、发布等 webhook，同时保持 agentic 行为：由 Qwen 总结和判断事件，而不是原样转发通知。
Reviewer Test Plan
如何验证
配置一个 daemon-managed channel，设置
approvalMode: "yolo"、webhook source secret 和目标 target。启动qwen serve，携带x-qwen-webhook-secretPOST 到/channels/:channelName/webhooks/:source，确认 worker 接受任务后返回202。同时确认错误路径：secret 错误返回401，未知 targetRef 返回404，worker 不可用返回503，IPC 超时返回504，成功接受的任务会通过 proactive channel send 发送 Qwen 的最终响应。本地已执行验证：
预期结果：base channel 测试通过，CLI 聚焦测试通过，build 通过，typecheck 通过。
Before & After 证据
Before：daemon-managed channels 没有经过鉴权的 HTTP webhook 入口，外部系统无法触发由 Qwen 生成的主动群消息。
After：
qwen serve可以鉴权配置化 webhook source，通过 channel worker 入队任务，带上 channel instructions/boundary 上下文运行 Qwen，并将生成结果主动发送到配置目标。测试平台
环境
macOS 本地 workspace，使用 Node/npm 仓库脚本。
风险与范围
approvalMode: "yolo"；配置错误的 source 或 target 会在 worker 执行前被拒绝。webhooks才启用。关联 Issue
