This is a well-executed security fix. The auto-approve behavior was always intended as temporary (the code literally says "Phase 5 will add interactive approval"), and this PR delivers exactly that. The implementation mirrors the existing tool call dispatch pattern, which makes it easy to follow and maintain. What I like: the lifecycle cleanup is thorough — five distinct paths (timeout, session cancel, process exit, bridge stop, session clear) all resolve pending permissions as cancelled, preventing agent turns from hanging indefinitely. The chat/thread/sender scoping in ChannelBase is the right level of granularity for group channels, preventing one user from approving another user's permission requests. The test coverage is exceptional — 40+ new tests covering the relay mechanism, edge cases (ambiguous multi-request lookups, cross-chat isolation, cross-thread isolation, authorization gating, option kind matching), and all cleanup paths. All 406 tests pass and typecheck is clean. No concerns worth blocking on. The 5-minute timeout is a reasonable default for unattended channel sessions. The PR is focused with no drive-by refactors or scope creep. Approving. ✅ 中文说明这是一个执行良好的安全修复。自动批准行为一直是临时的（代码中明确写着"Phase 5 will add interactive approval"），本 PR 正好交付了这个功能。实现参照了已有的 tool call dispatch 模式，易于理解和维护。 值得肯定的是：生命周期清理很全面——五条不同的路径（超时、会话取消、进程退出、bridge 停止、会话清除）都会将 pending 权限请求 resolve 为 cancelled，防止 agent turn 无限卡住。ChannelBase 中的 chat/thread/sender 限定对群组 channel 来说是正确的粒度，防止一个用户批准另一个用户的权限请求。 测试覆盖出色——40+ 个新测试覆盖 relay 机制、边界情况和所有清理路径。406 个测试全部通过，typecheck 无问题。 没有需要阻塞的顾虑。5 分钟超时对无人值守的 channel 会话是合理的默认值。PR 专注，没有顺手重构或范围膨胀。 批准。✅ — Qwen Code · qwen3.7-max |

[Suggestion] The requestPermission Promise has no timeout. The daemon/server ACP bridge has permissionResponseTimeoutMs (default 5 min) for exactly this scenario, but the channel path lacks it. If a user never responds, the ACP child process blocks indefinitely. While recovery paths exist (/clear, process exit), an unattended channel session can stall with no log or alert.
Consider adding a configurable timeout that resolves with { outcome: 'cancelled' } and emits permissionResolved for cleanup.

[Suggestion] formatPermissionRequest and approvalAlwaysLabel (lines 1258-1271) hardcode Chinese strings (需要授权执行命令, 命令：, 可回复：, 本次允许, 拒绝, 总是允许) while every other user-facing message in ChannelBase uses English ('Permission approved.', 'Permission denied.', 'No pending permission request for this chat.', etc.). Since ChannelBase is the shared base for Telegram, Discord, Slack, and all other channel types, non-Chinese-speaking users will see Chinese permission prompts mixed with English responses.
Consider translating to English to match the surrounding convention, or using a localization mechanism if i18n is planned.

[Suggestion] When respondToPermission throws, this catch block does not call removePendingPermission. The stale entry remains in both pendingPermissions and pendingPermissionsByChat maps until the session is cleared or dies. Adding this.removePendingPermission(pending.requestId) at the top of the catch block would prevent stale state from accumulating.

The 5-minute timeout in requestPermission silently cancels the permission with no stderr log. An agent appearing stuck for 5 minutes then resuming with no diagnostic output is a production observability gap. |
Add process.stderr.write(\[AcpBridge] permission request ${requestId} timed out after ${ACP_PERMISSION_RESPONSE_TIMEOUT_MS}ms (session=${pending.sessionId})\n`);` at the start of the timeout handler. |
packages/channels/base/src/ChannelBase.ts:298-309 + runtime.ts:201-205
|
Double cancellation on sendMessage failure: dispatchPermissionRequest's catch cancels the permission, then registerPermissionRelay's catch calls cancelPermissionRequest again (returns false, harmless but confused error ownership). |
Remove the internal cancel from dispatchPermissionRequest's catch and let the caller handle it, or don't re-throw after cancelling so the internal handler is authoritative. |
packages/channels/base/src/ChannelBase.test.ts |
canEnvelopeAnswerPendingPermission has negative tests for chatId and senderId mismatch but NOT for threadId mismatch. If the threadId check were removed, cross-thread approvals would silently succeed. |
Add a test where a permission is pending in thread-1 and /approve comes from thread-2 — should return "No pending permission request with that id for this chat." |
packages/channels/base/src/ChannelBase.ts:1217-1231 |
pendingPermissionForEnvelope filters through canEnvelopeAnswerPendingPermission before deciding ambiguous/found. No test covers 2 pending permissions where only 1 matches the current sender (should resolve to found, not ambiguous). |
Add a test with Alice and Bob both having pending permissions, where Alice sends /approve without an ID — should match only Alice's permission. |

Permission completion sequence (clearTimeout → delete → resolve → emit) is duplicated in 3 methods. Future changes (e.g., adding timeout logging) must be made in all 3 locations. |

[Critical] This uses the router's stored session target for permission delivery, but single scope reuses one session across chats while the router target remains the chat that first created the session. If Alice creates the single session and Bob later triggers a permission-requiring tool from another DM, the permission prompt is sent to Alice and Alice can approve Bob's tool call. dispatchToolCall already prefers activePrompts for this reason; permission requests need the same active-turn chat/sender routing, with threadId carried in the active prompt if threaded targets are supported.
const routeTarget = this.router.getTarget(event.sessionId);
const active = this.activePrompts.get(event.sessionId);

[Critical] The permission lookup only verifies chatId and threadId. In a group with sessionScope: 'user', sessions are private per sender, but any other allowed group member in the same chat/thread can reply /approve <request-id> or /approve when there is a single pending request and approve someone else's private tool permission. For non-shared targets, the lookup and the pending-per-chat key need to include or filter by the owning senderId; only shared sessions should allow another authorized member to answer.

There was a problem hiding this comment.
[Suggestion] When a permission request times out or is cancelled by the bridge (e.g., child process exit, session cancel), dispatchPermissionResolved only removes the pending entry — the user sees no notification. Their original permission prompt becomes dead, and a later /approve returns "No pending permission request for this chat" with no explanation.
Consider sending a user-facing message when the outcome is cancelled:
dispatchPermissionResolved(event: PermissionResolvedEvent): void {
const pending = this.pendingPermissions.get(event.requestId);
this.removePendingPermission(event.requestId);
if (pending && event.outcome?.outcome === 'cancelled') {
void this.sendMessage(
pending.target.chatId,
'Permission request timed out or was cancelled. Re-send your message to try again.',
).catch(() => {});

There was a problem hiding this comment.
[Suggestion] When router.getTarget() returns null or channels.get() returns null, cancelPermissionRequest is called with no diagnostic log explaining why the permission was cancelled. This makes production debugging difficult — an oncall engineer cannot distinguish a missing route from a missing channel from a timeout.
Add a log line before each cancellation:
if (!target) {
writeStderrLine(
`[Channel] No route for session ${sanitizeLogText(event.sessionId, 128)}; cancelling permission ${sanitizeLogText(event.requestId, 128)}`,
);
cancelPermissionRequest(bridge, event.requestId);

const channel = channels.get(target.channelName);

Code Review
Thorough code review confirmed:
- Race-free cleanup — All 5 pending-permission cleanup paths in AcpBridge are atomic (single-threaded Node.js guarantees)
- No memory leaks — Both AcpBridge.pendingPermissions and ChannelBase pending-permission maps have complete exit-path coverage
- Correct timeout — Uses unref() to avoid keeping the process alive; 5-minute timeout exported as constant
- Monotonic counter — permissionCounter never resets, guaranteeing unique request IDs
- Correct chat key — Null-byte-separated chatId+threadId handles DM, group, and threaded scenarios
- Safe ambiguous lookup — Lists up to 6 pending requests with tool titles when multiple exist
- Idempotent registration — registerPermissionRelay called on fresh bridge instances at all call sites
Verdict
APPROVE — Implementation is correct, well-tested, and safe to merge. No critical or blocking issues found.

There was a problem hiding this comment.
[Critical] dispatchPermissionRequest silently returns when permissionTargetForEvent yields undefined, but the bridge-side pending permission (with its 5-minute timeout) is never cancelled. In daemon mode there is a TOCTOU race: runtime.ts checks router.getTarget() and finds a valid target, then delegates to the channel, which re-checks routeTarget.channelName !== this.name. If the session was removed or re-routed between those two checks, the permission request is silently dropped and the ACP child process blocks for up to 5 minutes with no stderr output.

There was a problem hiding this comment.
[Critical] On bridge reconnect, registerPermissionRelay is called with the new bridge, but the channels' pendingPermissions and pendingPermissionsByChat maps are not cleared. The old bridge's resolvePendingPermissions fires on the old bridge, which the channel has already detached from via setBridge, so the channel never receives the cleanup events. Stale entries accumulate across restarts — a user typing /approve <stale-request-id> after reconnect gets "Permission request is no longer pending" but the channel-side entry is never cleaned up.
Consider clearing all channel pending permissions in setBridge (or at the reconnect call site) before attaching the new bridge:
// In setBridge or before registerPermissionRelay on reconnect:
for (const channel of channels.values()) {
channel.clearPendingPermissions?.();

There was a problem hiding this comment.
[Suggestion] Request IDs use a predictable sequential counter (acp-permission-${++this.permissionCounter}). In shared sessions (sessionScope='thread' or 'single' with empty allowedUsers), any authorized group member who observes the chat can enumerate IDs and race to approve a permission triggered by another user before the intended approver responds. This is defense-in-depth — the authorization model is sound for per-user sessions — but predictable IDs remove incidental protection in open shared sessions.

There was a problem hiding this comment.
[Suggestion] This explicit removePendingPermission call is always a no-op by the time it runs. bridge.respondToPermission in AcpBridge synchronously emits permissionResolved, which the bridgePermissionResolvedListener routes to dispatchPermissionResolved → removePendingPermission. The entry is already deleted before this line executes.
The redundant call obscures the data flow — readers may think the bridge does NOT emit permissionResolved. The catch-block call above (line 1496) is correctly defensive, but this post-success call can be removed.

There was a problem hiding this comment.
[Suggestion] When sendMessage fails inside dispatchPermissionRequest, the inner catch already cancels the AcpBridge pending permission and then re-throws. This outer .catch() calls cancelPermissionRequest again — a harmless no-op (returns false) — but the log line "Permission relay failed" is misleading because the cancellation actually succeeded inside the channel.
Consider either: (a) checking the return value of respondToPermission and logging differently when cancellation succeeded, or (b) having dispatchPermissionRequest not re-throw after successful in-method cancellation, making the ownership of cancellation responsibility unambiguous.

There was a problem hiding this comment.
[Suggestion] findScopedAlwaysOption and approvalAlwaysLabel both use endsWith('_${scope}') as a fallback after the canonical proceed_always_${scope} check. This matches any option ID ending in _project or _user, not just the known canonical IDs. If a future ACP server sends an allow_always option with an unexpected ID that happens to end in _project (e.g., sandbox_bypass_project), it would be selected and labeled as "always allow for this project" — potentially granting broader permissions than the user intended.

| } |
The same tightening should apply to approvalAlwaysLabel (lines 1401, 1407) — replace endsWith('_project') and endsWith('_user') with exact === 'proceed_always_project' and === 'proceed_always_user' checks.

[Suggestion] No test covers permission cleanup via onSessionDied. The /clear handler's removePendingPermissionsForSession is tested, but sessionDied is a separate code path triggered by ACP process crash or disconnect. If this cleanup were accidentally removed during a refactor, permissions from a dead session would remain pending indefinitely.
Consider adding a test that starts a session, emits a permissionRequest, emits sessionDied, then sends /approve <request-id> and asserts "No pending permission request with that id for this chat."

[Suggestion] The !this.bridge.respondToPermission guard is never tested. The test bridge always has respondToPermission defined, but the daemon facade conditionally omits it (see daemon-worker.ts:161-163). A bridge without permission relay support would hit this path, but there's no verification that the user receives the "Permission relay is not available" message rather than a crash.
Consider adding a test where respondToPermission is deleted from the bridge mock, a permission request is emitted, /approve is sent, and the response message is asserted.

Notes for the maintainer
- No defects surfaced. Relay, approve/deny/approve-always, option-scope selection, and owning-chat/thread/sender gating are proven live. Of the cleanup paths, session-cancel and child-exit are proven live (via the crashing subprocess); timeout / bridge-stop /
/clear/ bridge-replace / send-fail are covered by the PR suite (357 / 9). daemon-worker.tsglue (facade forwardingrespondToPermission+ theregisterPermissionRelaycall) I confirmed by reading; its 3 unit tests need the@qwen-code/sdkbuild, which has an unrelated env-level build failure in my sandbox (status 127) — covered by CI. The substantive relay logic is proven live and byruntime.test.ts.- Tradeoff (already stated in the PR): unattended channel sessions now pause up to the 5-min
ACP_PERMISSION_RESPONSE_TIMEOUT_MSand then auto-cancel the tool instead of silently approving. Bounded and safe (the timer isunref'd, so it never keeps the process alive). - Text-command UX only (no platform buttons/cards) — the PR flags this as intentional/out of scope.
Verdict: LGTM behaviourally. Solid, well-tested change that closes a real consent-bypass; safe to merge on this axis.

Part B —— 完整转发链路，实测（17/17）
真子进程 → 真 AcpBridge → 转发接线 → 真 ChannelBase → 捕获的聊天消息 → 来自归属 chat 的真实 /approve·/deny·/approve-always 命令，把正确的 ACP 选项路由回 agent。
/approve→ agent 收到proceed_once；聊天回Permission approved./deny→ agent 收到reject_once选项（cancel）/approve-always→ 正确选中项目级 always 选项（proceed_always_project），文案渲染为「always allow for this project」- 其他 chat 无法批准归属者的请求；归属 chat 仍可批准

给维护者的说明
- 未发现缺陷。 所有声称的行为（转发、批准/拒绝/永久批准、选项作用域选择、归属 chat/thread/sender 鉴权，以及 5 条清理路径 —— 超时 / 取消会话 / 子进程退出 / bridge 停止 /
/clear/ 替换 bridge）都能端到端复现。 daemon-worker.ts胶水层（facade 转发respondToPermission+ 调用registerPermissionRelay）我通过阅读确认；它的 3 个单测需要构建@qwen-code/sdk，而该构建在我的沙箱里有与本 PR 无关的环境级失败（status 127）—— 由 CI 覆盖。核心转发逻辑已由实测 +runtime.test.ts双重证明。- 权衡（PR 已说明）： 无人值守的 channel 会话现在最多暂停 5 分钟（
ACP_PERMISSION_RESPONSE_TIMEOUT_MS），随后自动取消工具，而非静默批准。有界且安全（定时器unref，不会阻止进程退出）。 - 仅文本命令 UX（无平台按钮/卡片）—— PR 已注明为有意为之/超出范围。
结论：行为层面 LGTM。 修复了一个真实的授权绕过问题，实现扎实、测试充分；在这个维度上可安全合并。

No review findings. Downgraded from Approve to Comment: CI still running.
Needs Human Review (low confidence — for human judgment)
1. Thread context mismatch in permission delivery (ChannelBase.ts:315, ChannelBase.ts:1326)
sendMessage(chatId, text) does not pass threadId, so the permission prompt lands in the main chat. But canEnvelopeAnswerPendingPermission requires an exact threadId match. In threaded conversations (Telegram forums, Feishu threads), a user replying from the main chat produces threadId: undefined which doesn't match the stored key. May make permission relay non-functional for threaded channel deployments.
2. sessionId fallback to toolCallId (AcpBridge.ts:352-356)
When request.sessionId is missing, toolCallId is used as sessionId. This never matches in router.getTarget(), so the permission is silently auto-cancelled with a misleading log. Unlikely to trigger in practice, but when it does, tool calls are silently dead on arrival.
3. /deny and /approve-always message text not asserted (ChannelBase.test.ts)
Tests verify respondToPermission call args but don't assert the user-visible response text for /deny ("Permission denied.") or /approve-always ("Permission approved always.").

[Suggestion] formatPermissionRequest only shows toolCall.title but omits toolCall.rawInput (the actual command arguments). A user is asked to approve or deny a tool based on a potentially vague title like "Run shell command" while the actual operation could be destructive (e.g., rm -rf /tmp/important). This is a confused-deputy risk: the title may not reflect the real action.
Consider including sanitized rawInput in the formatted message, especially for execute-kind tools:
| private formatPermissionRequest(pending: PendingPermission): string { | |
| private formatPermissionRequest(pending: PendingPermission): string { | |
| const { toolCall } = pending.request; | |
| const title = sanitizeQuotedText(toolCall.title || 'Tool use', 160); | |
| const alwaysOption = this.approvalAlwaysOption(pending); | |
| const input = toolCall.rawInput !== undefined | |
| ? sanitizeQuotedText( | |
| typeof toolCall.rawInput === 'string' ? toolCall.rawInput : JSON.stringify(toolCall.rawInput), | |
| 500, | |
| ) | |
| : undefined; | |
| const replies = [ | |
| '/approve allow once', | |
| ...(alwaysOption ? [`/approve-always ${alwaysOption.label}`] : []), | |
| '/deny deny', | |
| ]; | |
| const lines = [ | |

| '', | |
| 'Command:', | |
| title, | |
| ...(input ? ['', 'Input:', input] : []), | |

[Suggestion] The backward-compatibility fallback here uses (option as { kind?: string }).kind === undefined to match permission options that lack a kind field. The SDK type declares kind as required, so the cast bypasses TypeScript's type system. There is no comment explaining why this fallback exists — a future maintainer may remove it as dead code, breaking compatibility with older ACP agents that predate the PermissionOptionKind field.
Consider adding a brief comment:
| private approvalOptionId(pending: PendingPermission): string | undefined { | |
| private approvalOptionId(pending: PendingPermission): string | undefined { | |
| const options = pending.request.options; | |
| return ( | |
| options.find((option) => option.kind === 'allow_once')?.optionId ?? | |
| // Fallback for ACP agents that predate the PermissionOptionKind field | |
| options.find( |
The same pattern in denialResponse (matching optionId === 'cancel' when kind is undefined) would benefit from a similar comment.

LGTM, looks ready to ship. ✅

What this PR does
Routes ACP permission requests through channel chat instead of auto-approving them. Channel users can approve once, approve always when the ACP option is available, or deny the request from the owning chat or thread. Failed delivery, missing routes, session cancellation, process exit, and bridge stop now resolve pending permission requests as cancelled so agent turns do not hang.
Why it is needed
Channel standalone previously auto-approved ACP permission requests, which bypassed the user consent flow. Replacing that behavior with a relay keeps tool authorization explicit while preserving safe cleanup paths when the channel cannot deliver the prompt.
Reviewer Test Plan
How to verify
Run the focused channel tests and confirm permission requests are emitted, relayed, approved, denied, cancelled on failure, and cleaned up across session and process lifecycle paths.
Evidence (Before & After)
N/A for screenshots. Before this change ACP channel permission requests were auto-approved. After this change the channel sends a permission prompt and waits for /approve, /approve-always, or /deny.

中文说明
What this PR does
把 ACP 权限请求通过 channel 聊天转发，不再自动批准。channel 用户可以在归属 chat 或 thread 中选择单次批准、在 ACP 提供对应选项时永久批准，或拒绝请求。发送失败、路由缺失、会话取消、进程退出和 bridge 停止时，pending permission 会被 resolve 为 cancelled，避免 agent turn 卡住。
Why it is needed
channel standalone 之前会自动批准 ACP 权限请求，绕过用户授权流程。改为 permission relay 后，工具授权变成显式用户操作，同时在 channel 无法投递提示时仍保持安全清理。
Reviewer Test Plan
How to verify
运行聚焦的 channel 测试，确认 permission request 会被发出、转发、批准、拒绝、失败时取消，并在 session 和 process 生命周期中被清理。
Evidence (Before & After)
无截图。变更前 ACP channel 权限请求会自动批准。变更后 channel 会发送权限提示，并等待 /approve、/approve-always 或 /deny。
