feat(ipc): let a user-minted controller token drive a session without per-message review - #11090
Conversation
|
Thanks for the PR! Template looks good ✓ — every required heading is filled in, Problem: real, and already agreed in writing rather than theoretical. Part 1 of #10925 (merged as #11026) moved "sender asserts no review class" to hold for every receiver, which is correct for a stranger and makes a non-session program undeliverable-by-default. Part 3 of that same open issue is exactly this design, published before code existed "so it can be argued with", and #10118 lists it as M3 dependency 2. So there is a named downstream consumer waiting on it, and the mechanism was open for argument before this diff landed. This is a feature, not a Direction: aligned, and unusually faithful to the agreed design. I checked it against #10925 part 3 point by point: grant bound to a secret and not to a name ✓, reuse of the #10764 pattern (trust decided at the auth line, carried as a transport fact no frame can set) ✓, a third Size: 2668 changed lines — 1186 production, 1245 test, 237 docs. Core paths are touched ( Approach: the scope feels right, and it reuses rather than parallels. One genuine question worth an answer before merge, not a blocker: a minted grant is home-wide and unscoped — every session in that Qwen home accepts it until it is revoked. #10118's actual need is narrower ("handoff to a terminal session the user opened themselves"), and the PR defers per-directory/per-session scoping to a follow-up field on the record. Shipping the wide form first and narrowing later means the wide form is what real controllers get built against. Is that the intended order, or is the scoped grant the one that should land first? The PR's own answer — that scoping can be added as a field without touching the auth line or the gate — is reasonable, so this is a product call rather than a design defect. Risk: no high-risk path matched (the revert-correlated set is untouched). By subject matter this is Moving on to code review. 🔍 中文说明感谢贡献！ 模板完整 ✓ —— 所有必需标题都填了， 问题： 真实存在，而且是已经书面达成共识的，不是理论性加固。#10925 的第 1 部分（已作为 #11026 合入）把"发送方未声明审阅类别"对所有接收方改为 hold——这对陌生人是正确的，但也让"非会话程序"默认无法投递。同一个 open issue 的第 3 部分正是本 PR 的设计，在代码存在之前就公开"供讨论"；#10118 把它列为 M3 依赖 2。所以有一个明确的下游在等它，而且机制在本 diff 之前就已开放讨论。这是 feature 而非 方向： 对齐，而且对既定设计的还原度异常高。我逐条比对了 #10925 第 3 部分：授信绑定密钥而非名字 ✓、复用 #10764 的机制（在 auth 行决定信任、作为帧无法设置的传输层事实携带）✓、在 规模： 2668 行改动 —— 生产代码 1186 行、测试 1245 行、文档 237 行。触及核心路径（ 方案： 范围合理，而且是复用而非另起一套。合并前值得回答一个真实问题（不是阻塞项）：铸造出的授信是整个 Qwen home 范围、无作用域限定的——该 home 下每个会话都接受它，直到被撤销。#10118 的实际需求更窄（"handoff 到用户自己开的终端会话"），而本 PR 把按目录/按会话的作用域推迟为记录上的一个后续字段。先出宽版本、后再收窄，意味着真实的 controller 会先按宽版本来实现。这是预期的顺序吗？还是应该先落地带作用域的授信？PR 自己给的答案——加作用域只需在记录上加字段、不动 auth 行和闸门——是合理的，所以这是产品判断，不是设计缺陷。 风险： 未命中高风险路径（与回滚相关的那组文件未被触及）。但就主题而言这仍属 进入代码审查 🔍 — Qwen Code · qwen3.8-max-2026-09-02 Reviewed at |
… per-message review The gate holds every sender that asserts no review class, which makes an external program the user wants driving their session unusable. Give them a way to say so out of band: a token minted by hand, presented on the auth line, and classified by the transport the way the child token is. The file keeps only the token's hash, and sessions re-read it per connection, so a revocation takes effect with nothing to restart.
Code reviewI wrote my own proposal from the title and the "Why it's needed" section before opening the diff. It landed on the same mechanism — a user-minted secret presented on the auth line, only the hash stored, a third No critical blockers. Two suggestions and one doc-accuracy note. 1. 2. The envelope still renders the frame-chosen This is not a bypass and I am not calling it a blocker: 3. The hash-only rationale is stated more absolutely than it holds. The module header argues that a plaintext token would be a credential any session's model could be talked into printing, so only the hash is stored. True as far as it goes — but the same model can be talked into appending a record, minting itself a grant without ever handling plaintext. This is not a new escalation: that attacker can already write user-scope What I checked rather than assumedThe claims that are easy to get wrong in a change like this, verified against
The tests pin the changeWorth saying explicitly, because this is where a security PR usually turns out to be green and worthless. The two central claims have A/B proofs rather than assertions: The gaps are in composition, not in the units — see the lane line below. sequenceDiagram

Test evidenceThis is an unattended CI run, so nothing here was built or executed by the review — per the skill's rules I never run PR-derived code, and the agent environment holds a write PAT. The evidence below is the PR's own CI, fetched once from the check-runs API for the reviewed commit. I did not poll: the suite was still running when this was written, and the checks below are reported as they stood. Nothing is red, so there is no failing-job log to excerpt. The four substantive gates — Linux unit tests, lint and static analysis, integration tests, and the ink-vs-opentui parity snapshots — were all still in flight. The macOS and Windows unit matrices read
Sandboxed verification would settle the two things the unit suites structurally cannot, and the author has write access so both lanes are open. 中文说明代码审查我在打开 diff 之前，先只根据标题和"为什么需要"写了自已的方案。结论落在同一套机制上——用户亲手铸造的密钥、在 auth 行出示、只存哈希、第三种 没有关键阻塞项。 两条建议和一条文档准确性说明。 1. 2. controller 消息的信封仍然渲染帧里自选的 这不是绕过，我也不当作阻塞项： 3.

Confidence: 4/5 — solid, and the two things I found are defects against the PR's own stated invariants rather than against its security model; naming them, not blocking on them. I went into this expecting to argue for something smaller, because a 1186-production-line change that adds a credential class and a row to a security gate is the shape of PR that usually turns out to have a 20% version. It doesn't. I wrote my own proposal from the title and the motivation before opening the diff and it converged on the same mechanism, then I tried to break the convergence: OS peer credentials cannot separate a voice bridge from any other same-uid process, which is precisely the distinction a grant exists to make; the child token proves descent rather than authorization and cannot reach a daemon the session did not spawn; a settings key listing program names is a claim, and a claim is what the whole design is built to refuse. The only genuinely narrower version is a scoped grant, and the PR names that deferral itself with a credible path to it. That is not a reason to hold the PR — it is a product-ordering question I put to the author in Stage 1 and would want answered in the thread before merge, not a defect. The problem is real and I did not have to take the framing for it. Merged #11026 moved "sender asserts no review class" to hold for every receiver, which is correct for a stranger and parks everything a non-session program sends; this PR is part 3 of the same open issue, written as a design before code existed so it could be argued with, and #10118 names it as M3 dependency 2. So there is a consumer waiting, and the mechanism was open for objection before this diff. I checked the implementation against that design row by row rather than against the PR description, and it matches — including the part where it declines something the design proposed. Cutting the ephemeral What I would thank the author for in six months is that the comments carry reasoning instead of restating the code. Every non-obvious decision has its why adjacent — why only the hash is stored, why the read is synchronous, why the resolver is a function rather than a token list, why a malformed entry is skipped rather than fatal, why The tests are the part I spent most time on, because a security PR can be green and worthless. These are not. The two load-bearing claims have A/B proofs — the same bytes on the published peer token are still held, and a frame naming itself after a grant is still held with no attribution — so moving the trust decision off the connection fails the suite rather than passing it. Revocation-without-restart and mint-after-start run over a real socket against a real registry file written by the real functions. And the precedence test uses a resolver that says yes to everything, which pins peer/child-over-controller instead of assuming it. What is left is composition, and I named it in Stage 2 rather than papering over it: every integration test injects the registry-path seam, so the production default — the one path a real controller depends on — is asserted only as a mocked string; and the Neither of my two findings changes what the gate decides. The unguarded I am not approving in this run. CI was still in flight on this commit when I wrote this — Linux unit tests, lint and static analysis, integration tests and the parity snapshots had not reported — so there is no result to attest to yet. Approval is deferred until CI lands green on 中文说明信心：4/5 —— 扎实；我发现的两个问题是对 PR 自己声明的不变量的偏离，而不是对其安全模型的偏离。点名，但不阻塞。 我本来准备主张一个更小的方案，因为"1186 行生产代码、新增一类凭据、给安全闸门加一行"通常正是那种"其实存在 20% 版本"的 PR 形状。这次不是。我在打开 diff 之前只根据标题和动机写了自己的方案，结论收敛到同一套机制；随后我试着打破这个收敛：操作系统对端凭据无法把语音桥与任何其他同 uid 进程区分开，而这恰恰是授信要作出的区分；子令牌证明的是派生关系而非授权，且到不了会话自己没有派生的守护进程；列出程序名的设置键是一个"声明"，而整套设计存在的目的正是拒绝声明。唯一真正更窄的版本是带作用域的授信，而这个推迟是 PR 自己点名的，并给了可信的实现路径。这不是扣住 PR 的理由——它是一个产品顺序问题，我在 Stage 1 提给了作者，希望在合并前于线程里得到回答，但它不是缺陷。 问题是真实的，我不必照单接受它的表述。已合入的 #11026 把"发送方未声明审阅类别"对所有接收方改为 hold，这对陌生人是正确的，但会让非会话程序发的一切都被留置；本 PR 是同一个 open issue 的第 3 部分，在代码存在之前就以设计形式写出以便被质疑，而 #10118 把它列为 M3 依赖 2。所以有下游在等，而且机制在本 diff 之前就已开放异议。我是拿实现逐行对照那份设计、而不是对照 PR 描述来核的，结果一致——包括它拒绝设计中某一部分的那一处。砍掉会话内临时的 六个月后我会感谢作者的地方，是注释承载推理而不是复述代码。每一个不那么显然的决定，旁边都有它的为什么——为什么只存哈希、为什么读取是同步的、为什么解析器是函数而不是令牌列表、为什么畸形条目被跳过而不是让整个文件失效、为什么用 测试是我花时间最多的部分，因为安全 PR 完全可能"绿了但没用"。这次不是。两条承重的主张有 A/B 证明——同样的字节走已发布的 peer 令牌仍然被留置，一个把自己命名成某枚授信的帧仍然被留置且不带归属——所以把信任判定从连接上挪走会让套件失败，而不是让它通过。撤销无需重启、启动后铸造生效，都是经真实 socket、针对由真实函数写出的真实注册表文件跑的。而排序那条测试用一个对什么都说 yes 的解析器，从而钉住了 peer/child 高于 controller，而不是假设它。剩下的是组合层，我在 Stage 2 点名了而不是掩盖：每个集成测试都注入了注册表路径接缝，因此生产默认值——真实 controller 唯一依赖的那条路径——只被当作一个 mock 字符串断言过；而 我的两个发现都不改变闸门的判定。 本次运行我不批准。撰写时该提交上的 CI 仍在运行——Linux 单元测试、lint 与静态分析、集成测试、parity 快照都还没出结果——所以此刻没有可供作证的结果。批准将延迟到 CI 在 — Qwen Code · qwen3.8-max-2026-09-02 Reviewed at |

Reviewed at 0c7e9b0 against base 077c57d. No blockers — approving. Three Suggestions and three Nice-to-haves inline; none of them need to land before merge.
I started on 4704a55 and the branch was rebased onto current main mid-review. The rebase changed no TypeScript the PR touches — all 19 .ts/.tsx files are byte-identical between the two heads and the diff is still 21 files, +2604/−64 — so I re-ran everything below against 0c7e9b0 on the new base rather than carrying the old results over.
Verified locally on a clean worktree at the head SHA rather than taken from the description: npm run build, npm run typecheck, and eslint across all 19 changed .ts/.tsx files are clean. packages/core vitest run src/ipc gives 12 files / 432 tests passed, and packages/cli vitest run src/peerMessaging src/ui/commands/peers-command.test.ts src/commands/sessions gives 8 files / 192 passed — both exactly the numbers claimed. CI agrees on what has finished: Lint & Static and the no-AK Integration Tests both pass at this head.
The trust boundary holds. What I specifically checked:
- Origin can't be forged from a frame.
parsePeerFramereads noorigin/controllerfield,submitbuilds attribution only from the inbox callback, andcredential.controlleris assigned solely inauthKindOf's third branch (uds-inbox.ts:1042).escapeAttribute+flattenPeerLabelstrip quotes, angle brackets, newlines, control chars and bidi overrides, soorigin="controller"can't be smuggled in throughfromName. - Gate precedence matches the description. In
resolvePolicyevery explicit-setting and error return (policy-unreadableat :409 and :418,holdat :421,refuse/acceptat :424-426) sits above the controller accept at :437-439, soholdandrefuseboth still win, and the unknown-mode holds below it can't weaken a grant. - Admission precedence.
peer/childreturn beforecontroller; a throwing resolver fails closed to "not a controller"; an inbox with norequiredTokennever calls the resolver at all. - The file protections aren't dead switches.
atomicWriteJSONgenuinely implementsnoFollow(lstat rather than stat, andO_EXCL+fchmodon the open fd in the EXDEV fallback) andforceMode(skips permission preservation, so a 0644 copy restored from backup heals to 0600). The read path refuses a symlink and caps at 64 KiB. - Token handling. 256 bits from
randomBytes, hash-only on disk,timingSafeEqualwith no early exit, and theqpc_shape check runs before any I/O — so an ordinary peer connection really does cost zero syscalls. - A grant changes message admission only. The receiving session's own approval mode still gates every tool call the message asks for.
One thing I checked and am deliberately not raising: the registry is a plain file in the Qwen home, so a same-uid process can write its own grant into it. That isn't a delta from this PR — the same process can already read every session's ipcToken out of the peer directory, and ModeClass has only two values (inbound-gate.ts:140), so it can satisfy the parity rule by assertion in at most two frames. It can also write settings.json and global memory in that same directory. The Qwen home is already the trust root, and Risk & Scope is honest about the bearer-token scope.

A cluster that keeps producing siblings usually means the fixes are treating instances of a shared root cause — triaging that cause before the next round, or splitting an independent cluster into its own pull request, tends to end the loop faster than fixing them one at a time. Batching the remaining fixes and verifying them before the next push, or dropping this PR's reviews to --severity-floor critical, keeps the loop from re-deriving the same set. (Observation only — nothing was withheld from this review because of this observation.)

仅完成部分审查，审查缺口已披露。
未审查（原文为英文）：build-and-test — Test (windows-latest, Node 22.x), Test (macos-latest, Node 22.x) and Integration Tests (CLI, No Sandbox) were skipped in CI and their suites did not run locally; the platform-sensitive paths this PR adds (0600/0700 file modes and forceMode healing, symlink refusal via lstat, proper-lockfile behaviour) and the new qwen sessions controllers CLI surface were exercised on Linux only.
未审查（原文为英文）：test-efficacy probe — the harness could not be validated (harnessValidated: null, the positive control never produced a verdict): all 7 probes came back inconclusive because the probe runner tripped scripts/vitest-global-setup.js's build prerequisite guard, so 0 mutants and 0 hunks were probed. This is absent evidence about coverage gaps, not evidence of absent gaps; the mutation survivors reported in this review were each measured by a verifier's own scratch-tree probe instead..

[Suggestion] R2-5: (fix-induced) The catch-all clause added to this row states the unset default as "other messages are held for review", but under unset the parity rule auto-delivers the common case, and the clause lost its antecedent when the inline parity explanation was replaced with a link. An operator who reads this row concludes that leaving agents.crossSessionInbound unset parks cross-session messages for /peers review. Two sessions both in default mode are the same review class (modeClass(ApprovalMode.DEFAULT) is 'prompting') and the sender asserts that class in its frame (peer-send.ts:337), so resolvePolicy returns accept at inbound-gate.ts:466-468 and the message lands in the model's context with no review and no /peers entry — on a class claim nothing authenticates. The base row read only "Unset means review-class parity (see …)"; the two sibling surfaces that keep the same catch-all spell parity out first (settingsSchema.ts:3394, mirrored into settings.schema.json:1618, and commands.md:832-841), so this is the one surface that reads as "unset = everything reviewed".
Witness:
[probe] InboundGate.resolvePolicy, getPolicySetting: () => undefined, receiver DEFAULT
modeClass(DEFAULT): prompting modeClass(YOLO): bypass
unset + peer asserting "prompting" into a DEFAULT receiver: {"policy":"accept"}
unset + peer asserting "bypass": {"policy":"hold","cause":"mode-mismatch"}
unset + peer asserting nothing: {"policy":"hold","cause":"no-mode-asserted"}
Give the clause its antecedent, mirroring the schema wording: a message is delivered only when both sessions are in the same review class, and one from the other class — or from a sender that asserts none — is held for review. Then re-run npx prettier --check docs/users/configuration/settings.md (the row is formatter-clean today, and the table's column widths move). The rewrite must not claim peer messages are always held under unset, because return sender === modeClass(mode) at packages/core/src/ipc/inbound-gate.ts:466 accepts on a class match. No test pins this row, so there is nothing to redden.

本行新增的兜底子句把“未设置”的默认行为写成“其他消息会被扣留待审”，但在未设置时，review-class 对等规则会自动投递最常见的情形；而且当内联的对等规则解释被替换成链接后，这个子句失去了它的前件。运维者据此会以为不设置 agents.crossSessionInbound 就会把跨会话消息交给 /peers 审核。两个都处于 default 模式的会话属于同一 review class（modeClass(ApprovalMode.DEFAULT) 为 'prompting'），发送方会在帧中声明该 class（peer-send.ts:337），于是 resolvePolicy 在 inbound-gate.ts:466-468 返回 accept，消息在无人审核、/peers 中也无条目的情况下进入模型上下文——而这个 class 声明没有任何认证。修改前的行只写了“未设置即 review-class 对等（见…）”；保留同一兜底句的另外两处界面都先解释了对等规则（settingsSchema.ts:3394，并生成到 settings.schema.json:1618；以及 commands.md:832-841），因此这一处成了唯一读起来像“未设置=全部审核”的界面。请补回前件（仅当两个会话处于同一 review class 时才投递；来自另一 class、或未声明 class 的发送方则扣留待审），并重新运行 prettier。注意不要写成“未设置时 peer 消息一律扣留”，因为 inbound-gate.ts:466 在 class 匹配时是 accept。

There was a problem hiding this comment.
[Suggestion] R3-19: The core stub hardcodes its own copy of MAX_CONTROLLER_LABEL_CHARS, and both label-limit tests build their fixtures from that stub value via await import('@qwen-code/qwen-code-core') — so nothing connects the limit under test to the constant that defines it in the product, and the import that looks like it derives the boundary is self-referential. Core changes MAX_CONTROLLER_LABEL_CHARS (peer-controllers.ts:95) to 64, or down to 24: LABEL_COL (controllers.ts:37) and addPeerController's admission bound (peer-controllers.ts:553) both move automatically, yet this suite still manufactures fixtures from the stub's stale 40, still asserts they render in full, and stays green — the width boundary these tests exist to pin silently stops being the product's boundary, and a label the registry would now reject is tested as admissible forever. Nobody reading a green run can tell the number was invented 20 lines above the import that appears to derive it.
Witness:
[probe]
INTACT stub : real core MAX_CONTROLLER_LABEL_CHARS -> 40 ; stub literal in controllers.test.ts -> 40 ; cross-check probe 1 passed
DRIFT (stub 41): real core -> 40 ; stub literal -> 41 ; cross-check probe x expected 41 to be 40
controllers.test.ts under the same drift: Tests 21 passed (21)
Derive that one value from the real module instead of restating it, or add one cross-check test asserting the stubbed constant equals (await vi.importActual('@qwen-code/qwen-code-core')).MAX_CONTROLLER_LABEL_CHARS. The stub at controllers.test.ts:24-30 is what keeps this file from loading core's real entry — per AGENTS.md, packages/cli unit tests resolve workspace packages through their built dist/ — so read the single constant with vi.importActual rather than spreading the whole actual module into the factory and pulling all of core's dist into this unit test's graph. toValidRecord bounds the stored label by flattened.length > MAX_CONTROLLER_LABEL_CHARS (peer-controllers.ts:235) in code units, not display cells, so a derived-constant fix must not switch the fixtures to a width-based bound. The cross-check assertion must go red when core's constant moves and the stub literal is left behind; today the whole file stays green under that drift.
中文说明
core 的 stub 硬编码了自己的一份 MAX_CONTROLLER_LABEL_CHARS，而两个 label 长度测试都通过 await import('@qwen-code/qwen-code-core') 从这个 stub 值构造 fixture——因此被测的限制与产品中定义它的常量之间没有任何联系，那个看起来像是在推导边界的 import 其实是自指的。当 core 把 MAX_CONTROLLER_LABEL_CHARS（peer-controllers.ts:95）改成 64、或降到 24 时，LABEL_COL（controllers.ts:37）与 addPeerController 的准入上界（peer-controllers.ts:553）都会自动随之改变，而本测试套件仍然用 stub 中过时的 40 构造 fixture、仍然断言它们能完整渲染，并保持全绿——这些测试本来要固定的宽度边界，就静默地不再是产品的边界，一个注册表现在会拒绝的 label 会被永远当作可接受来测试。看到全绿结果的人无从得知，这个数字是在那个看似在推导它的 import 上方 20 行处凭空写下的。请从真实模块推导这一个值，而不是重述它；或者新增一个交叉校验测试，断言 stub 中的常量等于 (await vi.importActual('@qwen-code/qwen-code-core')).MAX_CONTROLLER_LABEL_CHARS。约束：controllers.test.ts:24-30 的 stub 正是让本文件不加载 core 真实入口的手段——按 AGENTS.md，packages/cli 的单元测试通过已构建的 dist/ 解析工作区包——因此请用 vi.importActual 只读取这一个常量，而不是把整个真实模块展开进工厂函数、把 core 的全部 dist 拉进这个单元测试的依赖图。toValidRecord 以 flattened.length > MAX_CONTROLLER_LABEL_CHARS（peer-controllers.ts:235）限制存储的 label，单位是码元而非显示单元格，因此“推导常量”的修复不得把 fixture 改成按宽度设界。当 core 的常量变化而 stub 字面量未跟上时，该交叉校验断言必须变红；今天在这种漂移下整个文件仍然全绿。

There was a problem hiding this comment.
[Suggestion] R3-2: The wide-label fixture is one display cell short of the widest label the registry admits, and the only column-alignment assertion in the file uses an ASCII fixture — so neither the LABEL_COL boundary nor padDisplay's width-aware branch is pinned. Core admits exactly MAX_CONTROLLER_LABEL_CHARS code units (peer-controllers.ts:235), i.e. 40 CJK units = 80 cells = the LABEL_COL - 2 budget; this fixture builds 79. Narrow the budget by one cell and a maximum-length CJK label clips to …, so two grants differing only in their final character render identically in qwen sessions controllers list and the user revokes the wrong controller — while this test stays green and the header assertion self-adjusts against the imported LABEL_COL. Separately, replacing stringWidth(str) with str.length in padDisplay (controllers.ts:51-55) also keeps all 21 tests green, because :191 uses ASCII fixtures where units equal cells; a registry holding 語音輸入 then pads 78 spaces instead of 74 and CREATED lands at a different cell offset on every CJK-labelled row.
Witness:
[probe] table geometry over seven label shapes
LABEL_COL=82 (PR): ascii-short rowCells=110 ; ADMITTED 40-CJK label: codeUnits=40 displayCells=80
LABEL_COL=81 with an 80-cell fixture: two distinct labels truncate to the same string (distinct=1 of 2)
mutation stringWidth(str) -> str.length in padDisplay: Tests 21 passed (21)
Use the admitted maximum in the fixture — a trailing 2-cell character (80 cells) rather than the 1-cell a/b, keeping the two labels distinguishable by their final character — and add a width-based alignment assertion: expect(stringWidth(row.slice(0, row.indexOf('2026-09-05')))).toBe(ID_COL + LABEL_COL) plus the equivalent for the header's CREATED. peer-controllers.ts:235 bounds the label with flattened.length > MAX_CONTROLLER_LABEL_CHARS in code units with MAX_CONTROLLER_LABEL_CHARS = 40 at :95, so the widened fixture must stay at exactly 40 code units, and the new assertion must compare against ID_COL + LABEL_COL rather than a literal or it breaks when core's limit moves. Setting LABEL_COL = MAX_CONTROLLER_LABEL_CHARS * 2 + 1 (controllers.ts:37) must turn this test red, and the stringWidth mutation must turn the new alignment assertion red; both survive the file today.
中文说明
宽 label 的 fixture 比注册表允许的最宽 label 少一个显示单元格，而文件中唯一的列对齐断言使用的是 ASCII fixture——因此 LABEL_COL 的边界与 padDisplay 的按宽度分支都没有被固定。core 允许恰好 MAX_CONTROLLER_LABEL_CHARS 个码元（peer-controllers.ts:235），即 40 个中日韩字符 = 80 单元格 = LABEL_COL - 2 的预算；而本 fixture 只有 79。把预算缩小一个单元格，最长允许的 CJK label 就会被截成 …，于是只有最后一个字符不同的两个授权在 qwen sessions controllers list 中渲染成完全相同的样子，用户会撤销错误的 controller——而本测试仍然是绿的，表头断言也会随导入的 LABEL_COL 自行调整。另一方面，把 padDisplay（controllers.ts:51-55）中的 stringWidth(str) 换成 str.length 同样能让 21 个测试全绿，因为 :191 用的是 ASCII fixture（码元数等于单元格数）；此时注册表中的 語音輸入 会补 78 个空格而非 74 个，CREATED 在每一行 CJK label 上的单元格偏移都会不同。请把 fixture 改为允许的最大值（末尾用一个 2 单元格字符，共 80 单元格，而不是 1 单元格的 a/b，并保持两个 label 仅末字符不同），并新增按宽度计算的对齐断言。约束：peer-controllers.ts:235 以码元为单位限制 label，MAX_CONTROLLER_LABEL_CHARS = 40（:95），因此加宽后的 fixture 必须恰好是 40 个码元；新断言应与 ID_COL + LABEL_COL 比较而非字面量。把 LABEL_COL 改为 MAX_CONTROLLER_LABEL_CHARS * 2 + 1 时本测试必须变红，stringWidth 变异时新的对齐断言必须变红——今天两者都能通过。

[Suggestion] R3-15: The new periodic revalidation treats every undefined from the resolver as a revocation, but readPeerControllerRegistrySync collapses every read failure into the same "no grants" answer — so a transient unreadable registry tears down live, still-granted controller connections, silently loses their in-flight frames, and logs a cause the code never established. The lenient reader returns emptyRegistry() for a non-regular file, an oversize file, any non-ENOENT read error (EMFILE under fd pressure, EACCES, EIO), a JSON parse failure and a schemaVersion mismatch, and never throws (peer-controllers.ts:256-318). Trigger: the user hand-edits <QWEN_HOME>/peer-controllers.json with an in-place save — atomicWriteFile falls back to a direct in-place writeFile on the ownership-preservation and EXDEV branches (atomicFileWrite.ts:263, :377), so the temp+rename guarantee does not cover a hand edit. The revalidation lands inside that window, the code sets refused = true and destroys the socket, the controller is disconnected mid-session with no delivery-status frame, and the frame it wrote after the drop is silently lost while the sender gets no error. The log asserts a revocation, sending the user to qwen sessions controllers list where the grant is intact a millisecond later. Same outcome for an EMFILE burst, or a newer build writing schemaVersion: 2 while an older session runs. Related, from the same walk: the line-deadline handler destroys the socket without setting refused, so when both timers fall due together the revalidation still runs on a dead connection, re-reads the registry and logs a revocation that did not happen.
Witness:
[probe] real inbox + real registry + real resolveControllerToken wiring; the grant record STAYS in the file
N5.1 delivered before: ["before"] N5.2 the file still names the grant: true
N5.3 readPeerControllerRegistrySync sees: [] N5.4 socket closed by the inbox: true
N5.5 log: ['DEBUG [PEER_CONTROLLERS] ignoring the controller registry ...: unsupported schemaVersion 2', (same again),
'DEBUG [PEER_IPC] dropping a controller connection whose grant was revoked']
N5.6 delivered after: ["before"] <-- the frame written post-drop is silently lost
N5.7 write after close errored: none <-- the sender gets no error either
N5.9 closed on invalid JSON: true N5.10 log: 'dropping a controller connection whose grant was revoked'
Do not assert a cause the code did not observe: reword to "dropping a controller connection whose grant no longer resolves (revoked, or the registry could not be read)", and set refused in the line-deadline destroy path so a dead connection cannot trigger a second registry read and a wrong-cause line. If the distinction is worth acting on, give the resolver a way to report "registry unreadable" distinct from "no such grant" and re-arm instead of destroying on unreadable — failing closed at admission while not tearing down an established connection on an I/O blip. PeerInboxOptions.resolveController states "It should not throw; one that does is treated as 'not a controller'" (uds-inbox.ts:352-370) and the wrapper's catch (:1069-1080) is pinned by treats a throwing resolver as "not a controller", so the authentication path must keep failing closed. A behavioural fix wants a case in describe.skipIf(isWindows)('controller grants') whose resolver reports the unreadable sentinel and asserts the connection survives to the next tick; today that condition is indistinguishable from revocation and the socket is destroyed, so the test is red without the fix. One correction to the filed wording: with debug logging on, PEER_CONTROLLERS does name the true cause on the preceding line — the finding holds because debug logging is off by default (isDebugLogFileEnabled() requires QWEN_DEBUG_LOG_FILE), so the user sees only a controller that stopped working.
中文说明
新增的周期性复核把解析器返回的每一个 undefined 都当作撤销处理，但 readPeerControllerRegistrySync 会把所有读取失败都归并为同一个“没有授权”的答案——因此一次短暂不可读的注册表就会断开仍然有效的活动 controller 连接、静默丢失其正在发送的帧，并记录一个代码从未真正确立过的原因。宽松读取器在遇到非常规文件、超大文件、任何非 ENOENT 的读取错误（fd 紧张时的 EMFILE、EACCES、EIO）、JSON 解析失败以及 schemaVersion 不匹配时都会返回 emptyRegistry()，且从不抛异常（peer-controllers.ts:256-318）。触发方式：用户以就地写入的方式手工编辑 <QWEN_HOME>/peer-controllers.json——atomicWriteFile 在保留属主分支与 EXDEV 分支上会回退为直接就地 writeFile（atomicFileWrite.ts:263、:377），因此“临时文件 + rename”的原子性保证并不覆盖手工编辑。复核恰好落在该窗口内，代码便设置 refused = true 并销毁 socket：controller 在会话中途被断开，没有投递状态帧，断开后写出的帧被静默丢弃，而发送方也收不到任何错误。日志断言这是一次撤销，把用户引向 qwen sessions controllers list，而那里授权一毫秒后依然完好。EMFILE 突发、或更新构建写入 schemaVersion: 2 而旧会话仍在运行时，结果相同。同一次走查还发现一个相关问题：line-deadline 处理会销毁 socket 却不设置 refused，因此当两个定时器同时到期时，复核仍会在一条已死的连接上运行、再读一次注册表，并记录一次并未发生的撤销。建议不要断言代码没有观察到的原因：改写为“正在断开一条其授权已无法解析的 controller 连接（可能被撤销，也可能注册表无法读取）”，并在 line-deadline 的销毁路径上设置 refused，使已死连接不会触发第二次注册表读取与错误归因的日志。如果这个区分值得据以行动，就让解析器能够把“注册表不可读”与“没有该授权”区分开，并在不可读时重新定时而不是销毁——在准入环节保持 fail-closed，同时不因一次 I/O 抖动就断开已建立的连接。约束：PeerInboxOptions.resolveController 声明“它不应抛异常；抛异常的会被当作‘不是 controller’”（uds-inbox.ts:352-370），其包装层的 catch（:1069-1080）由 treats a throwing resolver as "not a controller" 固定，因此认证路径必须继续 fail-closed。若要修行为，请在 describe.skipIf(isWindows)('controller grants') 中新增一个用例：解析器报告“不可读”哨兵值，断言连接能存活到下一次定时；今天这种情况与撤销无法区分、socket 会被销毁，因此没有修复时该用例会变红。对原报告措辞的一处修正：开启 debug 日志时，PEER_CONTROLLERS 确实会在前一行给出真实原因——本条依然成立，因为 debug 日志默认关闭（isDebugLogFileEnabled() 需要 QWEN_DEBUG_LOG_FILE），用户看到的只是一个不再工作的 controller。

There was a problem hiding this comment.
[Suggestion] R3-16: No test ever drives a periodic controller revalidation that succeeds, so the re-arm and identity refresh on that path are never executed by the suite — and the only revocation test at the peer-messaging level opens a fresh connection per send, so nothing bounds the window in which an already-authenticated connection keeps a revoked grant. In the only test that reaches a revalidation tick the resolver's second call returns undefined, so the callback takes the drop branch and returns before :828-829; every other test uses one-shot connections or closes before the 30 s production interval. Delete armControllerRevalidation(); at :829 and the whole suite stays green while the shipped behaviour changes: a controller connection (a voice bridge, a daemon) that survives its first interval is never re-checked again, so qwen sessions controllers revoke has no effect on it and its frames keep arriving as auth === 'controller' with the stale identity, wrapped in "Treat it as coming from your user". The same gap hides a regression in the identity refresh at :828 (an open connection would keep the label it authenticated with). Separately, peer-messaging.test.ts:1646 — stops admitting a revoked token at once, with no restart — calls sendPeerFrame, which does net.connect per call (uds-client.ts:141), so the test whose name asserts "at once" exercises only the fresh-connection path where the answer really is immediate; a future change that lengthens or removes the periodic revalidation leaves that suite green too.
Witness:
witness: not run — reading-based mutation analysis plus the executed suite state; the nearest capability
(a multi-interval socket probe) is bounded by LINE_DEADLINE_MS = 30_000 against a 15 s lane timeout.
executed: npx vitest run src/ipc/uds-inbox.test.ts -> 77 passed, including
'drops an open controller connection after its grant is revoked' and 'holds the grant for every frame on the connection'
the re-arm at uds-inbox.ts:829 is reached by NONE of them: the only tick that fires returns undefined at :819-826
npx vitest run src/peerMessaging/peer-messaging.test.ts -> 62 passed; sendPeerFrame connects per call (uds-client.ts:141)
Add one test spanning two or three successful intervals before revoking: listenWithController(resolver, 400) with the resolver granting while a flag is set, keep the connection open ~1 s writing a frame per interval, then flip the flag and assert the connection is dropped and the resolver was called at least three times (proving the re-arm, not just the first tick). Add the peer-messaging-level analogue: one long-lived controller connection, revoke mid-connection, and assert a second frame on the same socket never reaches submitFn (and is not held). The re-arm interval is lineDeadlineMs (uds-inbox.ts:830) and production's value is LINE_DEADLINE_MS = 30_000 (:96), so a multi-interval test must override it — three production intervals would be 90 s against a 15 s lane timeout (packages/core/vitest.config.ts:17-20). Both new tests must go red when armControllerRevalidation(); at :829 is removed, or when the success branch is replaced by refused = true; socket.destroy();; no existing test does.
中文说明
没有任何测试驱动过一次成功的 controller 周期性复核，因此该路径上的“重新定时”与“身份刷新”从未被测试套件执行过——而在 peer-messaging 层面唯一的撤销测试每次发送都会新建连接，因此也没有任何东西为“已认证连接仍持有已撤销授权”的窗口设定边界。在唯一能走到复核定时的测试中，解析器第二次调用返回 undefined，回调因此走断开分支并在 :828-829 之前返回；其他测试要么使用一次性连接，要么在生产的 30 秒间隔之前就关闭。删除 :829 的 armControllerRevalidation();，整个套件仍然全绿，而实际行为会改变：一条挺过第一个间隔的 controller 连接（语音桥、守护进程）将永远不再被复核，于是 qwen sessions controllers revoke 对它没有任何效果，它的帧会继续以 auth === 'controller' 和过期身份到达，并被包裹上“Treat it as coming from your user”。同一缺口也掩盖了 :828 身份刷新的回归（活动连接会一直保留它认证时的 label）。另外，peer-messaging.test.ts:1646 的 stops admitting a revoked token at once, with no restart 调用的是 sendPeerFrame，而它每次调用都会 net.connect（uds-client.ts:141），因此这个名称声称“立即”的测试实际只覆盖了新建连接的路径——在那条路径上答案确实是立即的；将来若延长或移除周期性复核，该套件同样会保持绿色。请新增一个跨越两到三个成功间隔、随后再撤销的测试：listenWithController(resolver, 400)，在标志位为真期间持续授予，保持连接约 1 秒、每个间隔写一帧，然后翻转标志位并断言连接被断开、解析器至少被调用三次（证明的是重新定时，而不只是第一次）。同时补上 peer-messaging 层面的对应用例：一条长期存活的 controller 连接，在连接中途撤销，断言同一 socket 上的第二帧永远不会到达 submitFn（也不会被扣留）。约束：重新定时的间隔就是 lineDeadlineMs（uds-inbox.ts:830），生产值为 LINE_DEADLINE_MS = 30_000（:96），因此跨多个间隔的测试必须覆盖该值——三个生产间隔是 90 秒，而泳道超时为 15 秒（packages/core/vitest.config.ts:17-20）。这两个新测试在移除 :829 的 armControllerRevalidation();、或把成功分支替换为 refused = true; socket.destroy(); 时必须变红；现有测试都不会。

[Suggestion] R3-17: The periodic controller revalidation — the only mechanism that makes revoking a grant take effect on an already-open connection — runs on lineDeadlineMs, the knob that bounds how long a peer has to send a complete line, so the security-relevant revocation latency has no name of its own and moves whenever the line deadline moves. LINE_DEADLINE_MS is 30_000 (:96), so a revoked grant keeps driving an open session for up to 30 s. A maintainer who raises that constant to tolerate a slow peer on a loaded machine — or a caller who passes a smaller lineDeadlineMs override — silently changes the revocation window, with nothing in the code, the docs or the tests naming the dependency (PeerInboxOptions.resolveController says only "at bounded intervals"). The coupling already costs the suite: the sole revalidation test must pass lineDeadlineMs: 120 (uds-inbox.test.ts:1067) to make the check fire, which shortens the line deadline to 120 ms too and is what leaves the within-window frame its ~40 ms of slack — the two meanings cannot be tuned apart.
Witness:
[probe] real socket + real registry, revocation through a registry rewrite, connection kept active — one variable
lineDeadlineMs=150 -> close-after-revoke=121ms resolverCalls=2
lineDeadlineMs=600 -> close-after-revoke=570ms resolverCalls=2
The revocation latency IS lineDeadlineMs (~1 interval each), i.e. 30 s in production, named nowhere.
Give the interval its own name and override: const CONTROLLER_REVALIDATION_MS = 30_000; plus controllerRevalidationMs?: number on PeerInboxOptions ("Override for tests"), armed with options.controllerRevalidationMs ?? CONTROLLER_REVALIDATION_MS, leaving lineDeadlineMs to the line reader only. /** Override for tests; production uses {@link LINE_DEADLINE_MS}. */ (uds-inbox.ts:382) with LINE_DEADLINE_MS = 30_000 (:96) means the line deadline's meaning and the tests relying on it killing an idle connection must not change; the same value drives arm(), so a separate revalidation interval set longer than the line deadline never fires on an idle controller connection — keep it at or below, or document that the connection dies first. drops an open controller connection after its grant is revoked re-expressed as listenWithController(resolver) with controllerRevalidationMs: 120 and the default line deadline goes red if armControllerRevalidation keeps using lineDeadlineMs (no revalidation fires inside the test, so await closed times out), and it no longer depends on line-deadline slack for the within-window frame. One correction, measured: an idle controller connection is still revalidated — both timers fire (resolverCalls=2 on the idle arm) — so do not quote the filed claim that the revalidation only engages while the controller keeps writing; the practical conclusion is unchanged because the connection dies at the line deadline either way.
中文说明
collector 的周期性复核——让撤销对一条已打开的连接生效的唯一机制——使用的是 lineDeadlineMs，也就是“peer 有多长时间发出一个完整行”的那个旋钮，因此与安全相关的撤销时延没有自己的名字，并且会随 line deadline 的变化而变化。LINE_DEADLINE_MS 为 30_000（:96），因此一个已撤销的授权仍能驱动一条打开的会话长达 30 秒。维护者若为了在负载较高的机器上容忍缓慢的 peer 而调大该常量——或调用方传入更小的 lineDeadlineMs 覆盖值——就会静默改变撤销窗口，而代码、文档与测试中都没有任何地方指出这一依赖（PeerInboxOptions.resolveController 只写了“按有界间隔”）。这种耦合已经在测试上造成代价：唯一的复核测试必须传入 lineDeadlineMs: 120（uds-inbox.test.ts:1067）才能让检查触发，这同时也把行超时缩短到 120 毫秒，正是这一点让 within-window 帧只剩约 40 毫秒的余量——两种含义无法分开调优。建议为这个间隔单独命名并单独提供覆盖项：const CONTROLLER_REVALIDATION_MS = 30_000;，并在 PeerInboxOptions 上增加 controllerRevalidationMs?: number（“供测试覆盖”），以 options.controllerRevalidationMs ?? CONTROLLER_REVALIDATION_MS 定时，把 lineDeadlineMs 留给行读取器。约束：uds-inbox.ts:382 的 /** Override for tests; production uses {@link LINE_DEADLINE_MS}. */ 与 :96 的 LINE_DEADLINE_MS = 30_000 意味着 line deadline 的语义、以及依赖它断开空闲连接的测试都不能改变；同一个值也驱动 arm()，因此若把独立的复核间隔设得长于 line deadline，它在空闲的 controller 连接上永远不会触发——请保持不大于它，或在文档中说明连接会先被断开。把 drops an open controller connection after its grant is revoked 改写为 listenWithController(resolver) 加 controllerRevalidationMs: 120、并使用默认 line deadline 后，如果 armControllerRevalidation 仍使用 lineDeadlineMs，该测试会变红（测试期间不会有复核触发，await closed 超时），并且它也不再依赖 line deadline 的余量来投递 within-window 帧。另有一处经实测的修正：空闲的 controller 连接仍然会被复核——两个定时器都会触发（空闲分支上 resolverCalls=2）——因此不要引用原报告中“复核只在 controller 持续写入时才起作用”的说法；实际结论不变，因为无论哪种情况连接都会在 line deadline 处断开。

[Suggestion] R2-10: (fix-induced) Six of the assertions in the test this round rewrote are each satisfied by other text in the same assembled prompt, so the controller carve-out they were written to pin can be deleted and the test still passes. buildClassifierSystemPrompt renders BUILTIN_SOFT_DENY into {{DEFAULT_SOFT_DENY}} before {{ENVIRONMENT}}; that list already contains crontab modifications (:45) and QWEN.md, AGENTS.md, … .qwen/hooks/, .qwen/fork-profiles/, and .mcp.json (:46), the sibling test at :36-41 guarantees both entries are in the same makeConfig({}) prompt, and this entry's own later clause supplies never lifts a boundary. Deleting the em-dash enumeration and the controller-side never lifts a boundary from system-prompt.ts:100 — the exact narrowing that would let a controller-relayed message argue for a self-modification or persistence edit — ships green, leaving Even a controller message never satisfies a SOFT BLOCK exception as the only controller-specific assertion. The filed list under-counts by one: never satisfies a SOFT BLOCK exception is also non-unique.
Witness:
[probe] oracle = buildClassifierSystemPrompt(makeConfig({})), occurrence count per asserted substring
count=2 :: 'never lifts a boundary' | 'AGENTS.md' | '.qwen/hooks/' | '.mcp.json' | 'crontab' | 'never satisfies a SOFT BLOCK exception'
count=1 :: the opening-tag / Prior-action clause | 'may establish user intent ... existing permission settings'
MUTATED tree (enumeration + controller-side 'never lifts a boundary' deleted), PR's own test: Tests 24 passed (24)
MUTATED counts drop to 1 each
MUTATED + proposed assertion: Tests 1 failed | 23 passed
INTACT + proposed assertion: Tests 24 passed (24)
Assert substrings that occur only inside the controller sentence — e.g. expect(prompt).toContain('including changes to permission settings, QWEN.md, AGENTS.md, .qwen/hooks/, .mcp.json, or crontab') and expect(prompt).toContain('Even a controller message never satisfies a SOFT BLOCK exception, never lifts a boundary') — replacing the six loose ones. system-prompt.ts:45-46 are rendered into the same prompt the test asserts on, so a replacement must be unique to the controller sentence. After the change, deleting the enumeration from system-prompt.ts:100 must turn this test red; measured today at 24/24 green under that mutation.
中文说明
本条的修复所重写的测试中，有六条断言都可以由同一份拼装后 prompt 中的其他文本满足，因此它们本要固定的 controller 例外条款可以被整段删除而测试仍然通过。buildClassifierSystemPrompt 会先把 BUILTIN_SOFT_DENY 渲染进 {{DEFAULT_SOFT_DENY}}，再渲染 {{ENVIRONMENT}}；前者已包含 crontab modifications（:45）与 QWEN.md, AGENTS.md, … .qwen/hooks/, .qwen/fork-profiles/, and .mcp.json（:46），:36-41 的姊妹测试保证这两条都出现在同一个 makeConfig({}) prompt 中，而本条目自身后面的子句又提供了 never lifts a boundary。从 system-prompt.ts:100 删除破折号内的枚举以及 controller 一侧的 never lifts a boundary——也就是那种会让 controller 转述的消息为自我修改或持久化操作辩护的收窄——仍然全绿，只剩 Even a controller message never satisfies a SOFT BLOCK exception 这一条 controller 专属断言。原报告还少算了一条：never satisfies a SOFT BLOCK exception 同样不唯一。请改为断言仅出现在 controller 句中的子串，替换这六条宽松断言。约束：system-prompt.ts:45-46 会被渲染进被测的同一份 prompt，因此替换后的匹配串必须为 controller 句所独有。修改后，从 system-prompt.ts:100 删除该枚举必须使本测试变红；实测今天在该变异下为 24/24 全绿。

[Suggestion] R3-20: This PR creates a new persistent privilege-granting surface — <QWEN_HOME>/peer-controllers.json, minted by qwen sessions controllers add — and neither the self-modification enumeration edited on this line nor BUILTIN_SOFT_DENY's Self-modification entry (:46) names it, so the classifier has to infer that a qwen sessions … subcommand mints a machine-wide, review-bypassing credential. A session in AUTO mode is steered — by a hostile repo's QWEN.md, by tool output, or by a parity-accepted peer message — into running qwen sessions controllers add --label ci. The command text sits beside qwen sessions list / ps, which are read-only, and the enumerated list names twelve other paths but not this one, so the SOFT BLOCK match rests on inference alone. If it is auto-approved, handleAdd prints the plaintext token to stdout, which lands in the tool result and therefore the transcript; any local process — or any network call the model is later talked into — can then present it, and every session on that Qwen home admits it as auth === 'controller' with no per-message review, while this same line tells the classifier such an envelope "may establish user intent for an ordinary action". The grant survives restarts until the user happens to run /peers controllers and revoke it. The notice's prohibition list is addressed to the model relaying the instruction, not to the classifier judging the minting command.
Witness:
[sweep] measured mentions of the new surface in the assembled classifier prompt
'peer-controllers.json' -> 0 'sessions controllers' -> 0
every leg read at 507ebbafdf:
gate live : permissions/autoMode.ts:866 -> classifyAction -> classifier.ts:156 baseSystemPrompt = buildClassifierSystemPrompt(input.config)
mint prints : controllers.ts handleAdd -> writeStdoutLine(` ${token}`) and the paste-ready auth line
admits unreviewed: ipc/inbound-gate.ts:434-437 if (origin?.controller) { return { policy: 'accept' }; } (crossSessionInbound unset)
persistent : getPeerControllerRegistryPath() -> <QWEN_HOME>/peer-controllers.json, re-read per auth line
witness: not run for the behavioural half — whether a real classifier auto-approves the command is a model
judgement and no provider is reachable in this harness; the nearest capability (a drive run of a live AUTO-mode
session) was not attempted because it would mint a real credential in the runner's Qwen home.
Add the new surface to the enumeration on this line (e.g. "… or the trusted-controller registry (qwen sessions controllers add / <QWEN_HOME>/peer-controllers.json)") and to BUILTIN_SOFT_DENY's Self-modification entry at :46 alongside .qwen/fork-profiles/ and .mcp.json. That entry enumerates .qwen/settings*.json, QWEN.md, AGENTS.md, QWEN.local.md, configured context filenames, .qwen/rules/, .qwen/commands/, .qwen/agents/, .qwen/skills/, .qwen/hooks/, .qwen/fork-profiles/, and .mcp.json — use the same path spelling in both so the lists do not drift. Every path in :46 is already covered by that entry's generic clause yet named anyway, so naming a surface explicitly is this list's established practice, not a new burden. In system-prompt.test.ts, add expect(prompt).toContain(...) for the new wording and confirm it goes red without the change — but per the separate finding on this test, assert a substring unique to the controller sentence, not a bare filename that BUILTIN_SOFT_DENY already supplies elsewhere in the same prompt.
中文说明
本 PR 新建了一个持久化的授权 surface——<QWEN_HOME>/peer-controllers.json，由 qwen sessions controllers add 签发——但无论是本行所编辑的自我修改枚举，还是 BUILTIN_SOFT_DENY 的 Self-modification 条目（:46），都没有提到它，因此分类器必须自行推断：某个 qwen sessions … 子命令会签发一个跨整机、可绕过审核的凭证。处于 AUTO 模式的会话可能被引导——通过恶意仓库的 QWEN.md、工具输出，或一条按对等规则被接受的 peer 消息——去执行 qwen sessions controllers add --label ci。该命令文本紧挨着只读的 qwen sessions list / ps，而枚举列表点出了另外十二个路径却没有这一个，于是 SOFT BLOCK 的匹配只能依赖推断。若它被自动批准，handleAdd 会把明文 token 打印到 stdout，从而进入工具结果、进而进入转录；此后任何本地进程——或模型后来被劝说的任何网络调用——都可以提交它，而该 Qwen home 上的每个会话都会以 auth === 'controller' 接受它、无需逐条审核，与此同时本行还告诉分类器这样的信封“可以为一个普通动作确立用户意图”。该授权会跨重启存活，直到用户碰巧运行 /peers controllers 并撤销它。通知文本中的禁止清单是对转述指令的模型说的，而不是对判断签发命令的分类器说的。建议在本行的枚举中加入这个新 surface（例如“… or the trusted-controller registry (qwen sessions controllers add / <QWEN_HOME>/peer-controllers.json)”），并在 :46 的 Self-modification 条目中与 .qwen/fork-profiles/、.mcp.json 并列加入。该条目枚举了 .qwen/settings*.json, QWEN.md, AGENTS.md, QWEN.local.md, configured context filenames, .qwen/rules/, .qwen/commands/, .qwen/agents/, .qwen/skills/, .qwen/hooks/, .qwen/fork-profiles/, and .mcp.json——请在两处使用相同的路径写法，避免两份列表漂移。:46 中的每个路径其实都已被该条目的通用子句覆盖，却仍被逐一点名，因此显式点名一个 surface 是这个列表的既有做法，并非新增负担。在 system-prompt.test.ts 中为新措辞添加 expect(prompt).toContain(...) 并确认没有该改动时它会变红——但请按针对该测试的另一条发现所述，断言一个仅为 controller 句所独有的子串，而不是一个 BUILTIN_SOFT_DENY 已在同一 prompt 别处提供的裸文件名。

Findings keep coming back to the same files: packages/core/src/ipc/inbound-gate.ts (findings in round 3; 3 more now); packages/core/src/ipc/peer-controllers.ts (findings in rounds 2, 3; 1 more now). A cluster that keeps producing siblings usually means the fixes are treating instances of a shared root cause — triaging that cause before the next round, or splitting an independent cluster into its own pull request, tends to end the loop faster than fixing them one at a time. (Observation only — nothing was withheld from this review because of this observation.)
Mechanism health: this round did not close cleanly, so it withholds the incremental anchor — and the round it recovered had no anchor this round could use either — none at all, one with no certifier, one certified by an identity other than the one this round runs under, or one this round's fetch refused or resolved to the head — so the next review re-reads the whole diff unless recovery grafts an earlier own anchor that the round running it can use onto the complete work list this round leaves behind, and keeps doing so until a round's marker carries an anchor again or a graft lands that the round running it can use. (Stated, not acted on — this changes nothing about what the round posts.)

[Suggestion] R4-15: forgetController is the only buffer-reading entry point on InboundGate that does not call expireOverdue() first. admit (:523), decide (:640) and reevaluate (:692) each open with the sweep, under the class comment at :520-522 — "Timers can be starved or slept through (a suspended laptop), so every entry point sweeps before it reads the buffer rather than trusting the timer to have fired." The entry point this round added does not, so it counts, strips and re-parks entries whose hold has already run out, and its return value feeds a user-facing promise the gate cannot keep.
A controller message is parked under an explicit hold with a 60-minute lifetime; the machine suspends for two hours (CLOCK_MONOTONIC does not tick and the unref'd expiry timer does not fire). On resume the user's first action is /peers revoke c_0123abcd. forgetController still finds the overdue entry, strips it, returns 1 and fires notifyHeldChange() with the dead entry still in the array — so peers-command.ts:281-288 prints "1 held message from it remains parked for review as an ordinary peer message" and the TUI re-publishes a hold announcement for a message that no longer counts. The user runs /peers, sees it as ", expiring now", and /peers accept <id> answers 'gone', because decide's own sweep expires it on the spot. The revoke announced a review that cannot happen, and the sender's expired receipt is deferred until some unrelated entry point sweeps.
Witness:
[probe] fake timers, policy 'hold', heldExpiryMs 60_000, wall clock jumped +2h
with timers unadvanced (the suspended-laptop model)
INTACT A.forgetController.return: 1 A.heldAfterForget: [{cause:"explicit-setting"}]
A.statusesAfterForget: ["held"] <- no 'expired' receipt
A.decideApprove: "gone" <- the announced review cannot happen
B (sibling arm, decide first) B.forgetController.return: 0
FIXED A.forgetController.return: 0 A.heldAfterForget: []
A.statusesAfterForget: ["held","expired"]
inbound-gate.test.ts 107 passed (107) with the one-line fix applied
| /** Remove a revoked grant's authority from messages already waiting. */ | |
| forgetController(id: string): number { | |
| let forgotten = 0; | |
| /** Remove a revoked grant's authority from messages already waiting. */ | |
| forgetController(id: string): number { | |
| this.expireOverdue(); | |
| let forgotten = 0; |
The fix must not add a second notification or re-arm: expireOverdue() already early-returns on an empty buffer or a null lifetime (:900, :906) and already ends with this.notifyHeldChange() followed by this.rescheduleExpiry() (:917-921), so forgetController must keep its own if (forgotten > 0) this.notifyHeldChange(); gate and nothing else.
Please add the test named below and confirm it goes red with the added sweep removed: a case in the controller grants describe of inbound-gate.test.ts under vi.useFakeTimers() that parks a controller frame with policy: 'hold' and heldExpiryMs: 60_000, jumps the clock past the lifetime with vi.setSystemTime (not advanceTimersByTime, so the armed timer does not sweep first), then asserts gate.forgetController(VOICE.id) returns 0, getHeld() is empty and statuses contains { msgId, status: 'expired' }.
中文说明
forgetController 是 InboundGate 上唯一一个在读缓冲区之前不调用 expireOverdue() 的入口。admit（:523）、decide（:640）与 reevaluate（:692）都以该清理开头，依据是 :520-522 的类注释——"定时器可能被饿死或被睡过去（合上的笔记本），所以每个入口都在读缓冲区之前先清理，而不是相信定时器已经触发过。"本轮新增的这个入口没有这样做，因此它会对留置期已经到期的条目进行计数、剥除归属并重新留置，而它的返回值又支撑着一句 gate 无法兑现的用户可见承诺。
具体过程：一条 controller 消息在显式 hold 下被留置，留置期 60 分钟；机器休眠两小时（CLOCK_MONOTONIC 不走，unref 的到期定时器也不触发）。恢复后用户的第一个动作是 /peers revoke c_0123abcd。forgetController 仍会找到这个已超期的条目、剥除其归属、返回 1，并在数组里仍留着这个死条目的情况下触发 notifyHeldChange()——于是 peers-command.ts:281-288 打印"1 held message from it remains parked for review as an ordinary peer message"，TUI 也会为一条已不再计入的消息重新发布一次留置提示。用户执行 /peers，看到它显示", expiring now"，而 /peers accept <id> 回答 'gone'，因为 decide 自己的清理当场让它过期。这次撤销宣告了一场无法进行的审阅，而发送方的 expired 回执被推迟到某个无关入口执行清理时才发出。
修复不得增加第二次通知或重新定时：expireOverdue() 在缓冲区为空或留置期为 null 时已经提前返回（:900、:906），并且在结束时已经调用 this.notifyHeldChange() 与 this.rescheduleExpiry()（:917-921），因此 forgetController 只需保留它自己的 if (forgotten > 0) this.notifyHeldChange();，不要额外再加。
请补上下述测试，并确认移除新增的清理调用后它会变红：在 inbound-gate.test.ts 的 controller grants describe 下、vi.useFakeTimers() 中新增一个用例，以 policy: 'hold' 与 heldExpiryMs: 60_000 留置一条 controller 帧，用 vi.setSystemTime（而不是 advanceTimersByTime，以免已定时的定时器先做清理）把时钟推过留置期，然后断言 gate.forgetController(VOICE.id) 返回 0、getHeld() 为空、且 statuses 含 { msgId, status: 'expired' }。

[Suggestion] R4-16: Nothing in the suite exercises forgetController with two distinct grants parked, so the by-id filter that keeps a revoke from de-authorizing an unrelated, still-valid controller is unpinned. Every existing test mints exactly one grant: inbound-gate.test.ts:1195-1207 parks a single VOICE frame, and all seven peer-messaging.test.ts grants are grant('voice bridge') (:1607, 1633, 1647, 1675, 1721, 1751, 1774) — the file holds exactly one PeerControllerIdentity literal (:1114).
Widen this comparison to if (!entry?.controller) continue;, or hand forgetController the wrong handle, and every test still passes while revoking grant A also strips grant B's identity from B's parked messages. The cost lands on the user: formatHeldList derives both the label and the origin tag from entry.controller (peers-command.ts:114-125), so B's still-authorized messages start rendering as [peer] unknown session instead of [controller] <B's label> on the very screen where the user decides whether to release them, and a later reevaluate resolves them by parity — a controller frame asserts no fromMode, so they take cause no-mode-asserted and sit until expiry instead of being released, silently dropping delivery for a grant that was never revoked.
Witness:
[probe] MUTANT (`entry.controller?.id !== id` -> `!entry?.controller`):
src/ipc/inbound-gate.test.ts 107 passed (107) <- mutant undetected
two distinct identities parked (VOICE c_0123abcd, CI c_9999ffff),
forgetController(VOICE.id):
INTACT forgotten: 1 "from ci" keeps controller: {id:"c_9999ffff",label:"ci"}
MUTANT forgotten: 2 "from ci" controller: null
Add a case to the controller grants describe that parks two frames under two different identities (e.g. VOICE and { id: 'c_9999ffff', label: 'ci' }), calls forgetController(VOICE.id), and asserts it returns 1, that the other entry still has controller set, and that clearing the policy then releases only the surviving grant's message with its identity intact.
The new case belongs in inbound-gate.test.ts, which imports the gate from source: peer-messaging.test.ts resolves InboundGate through the built core dist, so it cannot observe a core source mutation at all.
Please add that test and confirm it goes red when the id comparison is widened to "any controller identity" — that is the mutation no current test detects.
中文说明
整个测试套件里没有任何用例在同时留置两个不同授信的情况下执行 forgetController，因此"按 id 过滤、使一次撤销不会剥除另一个无关且仍然有效的 controller 的权威"这个保护没有被钉住。现有测试每个都只铸造一枚授信：inbound-gate.test.ts:1195-1207 只留置一条 VOICE 帧，peer-messaging.test.ts 的七处授信全部是 grant('voice bridge')（:1607、1633、1647、1675、1721、1751、1774），该文件里只有一处 PeerControllerIdentity 字面量（:1114）。
把这个比较放宽成 if (!entry?.controller) continue;，或者把错误的 handle 传给 forgetController，所有测试依然全绿，而撤销授信 A 会同时剥除授信 B 留置消息上的身份。代价落在用户身上：formatHeldList 的 label 与来源标记都取自 entry.controller（peers-command.ts:114-125），于是 B 那些仍然有效的消息开始在"用户决定是否放行"的那一屏上渲染成 [peer] unknown session 而不是 [controller] <B 的 label>；随后的 reevaluate 会按对等规则判定它们——controller 帧不声明 fromMode，因此它们的 cause 变成 no-mode-asserted，一直留置到过期而不是被放行，等于静默地丢弃了一个从未被撤销的授信的投递。
请在 controller grants describe 里新增一个用例：用两个不同的身份（例如 VOICE 与 { id: 'c_9999ffff', label: 'ci' }）各留置一帧，调用 forgetController(VOICE.id)，断言它返回 1、另一个条目的 controller 仍然存在、且随后取消策略设置时只放行存活那枚授信的消息并保留其身份。
新用例应放在 inbound-gate.test.ts（它从源码导入 gate）：peer-messaging.test.ts 通过已构建的 core dist 解析 InboundGate，因此根本无法观察到 core 源码的变异。
请补上该测试，并确认把 id 比较放宽为"任何 controller 身份"后它会变红——那正是当前没有任何测试能发现的变异。

[Suggestion] R4-18: This round's fix made an unchanged comment false. removePeerController's contract comment states, as universal revocation semantics, that a parked message "stays parked under its original attribution" and that revocation "decides what happens on the next connection, which is the only thing a token can decide". Commit 816f5f22ca added InboundGate.forgetController and wired /peers revoke to call it (peers-command.ts:278-279), which strips entry.controller and recomputes the hold cause; HeldMessage.controller's own doc says the opposite — "The in-session revoke path removes this identity before the message can be released or re-evaluated" (inbound-gate.ts:227-228) — and the user-facing copy agrees ("remains parked for review as an ordinary peer message", peers-command.ts:283-288). The comment quoted here is accurate only for the out-of-session path.
Unresolved thread R3-18 (locations 1 and 2, peer-controllers.ts:53 and :606) instructs the author that "The still-true half of :601-604 ('…one that is parked stays parked under its original attribution') must survive the edit." An author following that instruction verbatim now preserves a clause this round's fix contradicts, so the two documents a reader consults for revocation semantics keep giving opposite answers for the path users actually take. The cost is not only documentation: a maintainer adding a second revoke entrance reads this JSDoc as authoritative, concludes parked attribution is deliberately untouched, and omits the forgetController call — which is exactly the divergence the Critical on inbound-gate.ts:455 measures, and this comment is what makes that omission look intentional rather than a bug.
Witness:
[probe] both behaviours pinned green against the two contradictory texts:
core vitest run src/ipc/inbound-gate.test.ts -t 'forgets a revoked grant'
1 passed | 106 skipped
cli vitest run src/peerMessaging/peer-messaging.test.ts -t 'keeps a revoked
controller message parked' 1 passed | 62 skipped
peer-controllers.ts:604-607 "stays parked under its original attribution"
inbound-gate.ts:227-228 "The in-session revoke path removes this identity"
Scope the claim to this function instead of to the system, e.g. "This only changes what the file says; it touches no in-memory state. A caller that holds parked messages must strip their controller attribution itself — see InboundGate.forgetController — or they keep the grant's framing after revocation." Fold this into the R3-18 aggregate edit rather than making a third pass over the same sentences, and note in that thread that the clause it asked to preserve is no longer true.
The fix must not violate peer-messaging.test.ts:1786-1787 — expect(m.forgetController(id)).toBe(1) followed by expect(m.getHeld()[0].controller).toBeUndefined() — which pins the stripping behaviour, so resolving the contradiction by changing behaviour rather than the comment must update that test in the same commit.
中文说明
本轮的修复使一段未改动的注释变成了假话。removePeerController 的契约注释把"留置中的消息保持其原有归属"以及"撤销决定的是下一次连接发生什么，而这正是令牌唯一能决定的事"写成了普适的撤销语义。提交 816f5f22ca 新增了 InboundGate.forgetController 并把 /peers revoke 接到它上面（peers-command.ts:278-279），这会剥除 entry.controller 并重算留置原因；HeldMessage.controller 自己的注释说的恰恰相反——"会话内的撤销路径会在消息被放行或重新判定之前移除这个身份"（inbound-gate.ts:227-228）——用户可见的文案也一致（"remains parked for review as an ordinary peer message"，peers-command.ts:283-288）。此处引用的注释只对会话外的那条路径成立。
未解决的讨论串 R3-18（位置 1 与 2，peer-controllers.ts:53 与 :606）要求作者":601-604 中仍然成立的那一半（'……留置中的保持其原有归属'）必须在本次编辑中保留"。作者若照此逐字执行，现在就会保留一条被本轮修复推翻的句子，于是读者查询撤销语义时会去看的两份文档，对用户实际走的那条路径继续给出相反的答案。代价不只是文档：一位要新增第二个撤销入口的维护者会把这段 JSDoc 当作权威，认定留置归属是刻意不动的，从而省略 forgetController 调用——这正是 inbound-gate.ts:455 上那条 Critical 实测到的分歧，而这段注释正是让该省略看起来像有意设计而非 bug 的东西。
请把这句断言限定到本函数，而不是整个系统，例如："这只改变文件所写的内容；它不触碰任何内存状态。持有留置消息的调用方必须自行剥除这些消息的 controller 归属——见 InboundGate.forgetController——否则它们在撤销之后仍保留该授信的外框。"请把这一处并入 R3-18 的聚合修改，不要对同几句话做第三轮改动，并在该讨论串里说明它要求保留的那半句已不再成立。
修复不得违反 peer-messaging.test.ts:1786-1787——expect(m.forgetController(id)).toBe(1) 之后紧跟 expect(m.getHeld()[0].controller).toBeUndefined()——它们钉住了剥除行为；因此若选择通过改变行为而不是改变注释来消除矛盾，必须在同一次提交里更新该测试。

Approved at head a7a3a43a.
The revocation chain that took four rounds to close is closed on this commit. Round 4's only Critical, R4-1 (inbound-gate.ts:457), was that a revoked grant kept its authority over messages already parked in every session except the one running /peers revoke — reachable with qwen sessions controllers remove, with a revoke issued from another session, and with a hand edit of peer-controllers.json. a7a3a43a removes the per-caller coupling: PeerMessaging.withControllerValidity (peer-messaging.ts:630-649) takes one registry snapshot per operation, scrubs the startup/backpressure buffer against it, and installs it behind isControllerValid, which InboundGate consults at getHeld() (:364), decide() (:663) and reevaluate() (:716). I checked that this covers every way a parked message can leave the gate: forgetControllersWhere (:386-404) deletes the identity from a copy and recomputes the cause through resolvePolicy(frame, originOf(next)), so the if (origin?.controller) return accept branch can no longer be reached with a dead grant; the only other bulk removal from held is shutdown() (:801), which reports every entry expired and delivers nothing. PeerMessaging.getHeld() is the sole accessor used by /peers and the held-list listeners, and it is wrapped — no production caller reaches gate.getHeld() directly.
Three details I went looking for and found handled correctly. The callback's default is fail-toward-preserving (validControllerIds?.has(id) ?? true), so an unwrapped internal call strips nothing rather than honoring anything; a nested deliver → buffered-flush inside a wrapped operation takes the early return and so cannot clear the outer snapshot mid-operation; and a registry that cannot be read yields an empty id set, which strips authority rather than granting it. matchControllerToken still compares hashes with timingSafeEqual behind a length check and scans the full registry without an early return. The new regressions are the right shape: they revoke through removePeerController on disk (not through the in-session command) and then assert reevaluate releases 0, the entry stays held as no-mode-asserted with controller undefined, and the submitted model text carries no origin="controller" — the witness round 4 asked for, and the forgets every invalid id removed with the same credential case pins the widened predicate rather than only the id it was named for.
Not blocking, worth a follow-up. forgetController now returns the count of all identities it stripped, so the in-session revoke confirmation can over-report messages belonging to a different grant; that is the same family as open R4-15 (this entry point is the only buffer reader that skips expireOverdue() first) and R4-18 (the removePeerController JSDoc still describes parked attribution as untouched). Two other open threads are about reliability rather than polish: R2-7 (a proper-lockfile compromise still lets mutate() commit its stale snapshot, which can put a revoked record back on disk) and R3-9 (removePeerController writes back only the entries it validated, so revoking one grant can drop unrelated siblings of a malformed registry). R3-15 notes that a transient read error therefore de-authoritizes live grants silently — safe in direction, but worth distinguishing from "no such grant" if this surface grows. 34 Suggestion threads remain open; none is a Critical, and round 4's own review deferred its 9 probes rather than requesting them.
CI facts. On this head Test (ubuntu-latest) passed in 22m1s, Lint & Static in 15m50s, Integration Tests (no-AK) in 9m48s, plus web-shell E2E Smoke, the OpenTUI no-flicker gate, the TUI parity snapshots and both Desktop Shell lanes; only review-pr was still running, and nothing has reported red. Test (macos-latest) and Test (windows-latest) are skipped by PR classification here, so the platform-sensitive parts (0600/0700 healing, the lstat symlink refusal, proper-lockfile) are covered on Linux only — disclosed by round 4 as a review gap, and unchanged by this commit. The page still reads CHANGES_REQUESTED because that verdict is anchored at 6c9ac758; the only commit since is the fix above, so a /triage re-run is what clears the stale state.

Verified the round-4 Critical (R4-1) against the fix commit a7a3a43 at this head — it closes the class at the root, as requested:
- The gate gained an optional
isControllerValidliveness hook (default: valid), consulted byforgetInvalidControllers()ahead of every release/listing entry (getHeld,decide,reevaluate); PeerMessaging wires it to the resolved controller-registry path viawithControllerValidity, one synchronous registry read per round with the Set shared across nested calls and cleared infinally. - All non-
/peers revokegrant-death routes now strip parked authority fail-closed: the CLIcontrollers removeverb, revocation from another session, and hand-edited/corrupt registry files (unreadable registry → empty Set → de-attribution, never a throw into the UI); the same-tokenHash sub-route is covered by the widenedforgetControllerpredicate, and the startupbufferedqueue is cleaned in the same round. - Stripping only de-attributes the entry back to the parity rules (held as
no-mode-asserted/mode-mismatch) — it never drops, releases, or rejects; manual/peers acceptstill works and no longer sees stale controller attribution. - The two tests R4-1 named exist verbatim (external revocation stays parked without authority; gate-level mirror), plus decide-path, buffered-path and same-credential cases; deleting any leg of the fix reddens them, and the pre-existing attribution-preservation cases pin the other direction (valid grants keep their controller envelope).
Non-blocking follow-ups worth recording: de-attribution is destructive, so a transiently unreadable registry permanently downgrades legitimate parked entries to manual-accept (bounded by the 5-minute hold in practice); forgetController's return now counts every stripped entry so the revoke confirmation text can overstate "from it"; and the pre-existing 30 s active-connection revalidation window in the inbox (admit() doesn't consult the hook) is unchanged by this commit — a separate design tradeoff if anyone wants to close it.
Test (ubuntu), Lint & Static and Integration Tests (no-AK) are green on this head. The 32 open threads are all round-3/4 Suggestions — recorded, non-blocking per the repo's severity convention. Dismissing the stale round-4 CHANGES_REQUESTED (its only Critical is the one verified fixed here), separately.
Its only Critical (R4-1, revocation not stripping authority from parked messages outside the same-session /peers revoke route) is fixed by a7a3a43 and verified at this head: the isControllerValid hook is consulted before every release/listing entry, all grant-death routes fail closed, and the requested tests are pinned. See the approving review for the item-by-item verification.

What this PR does
The inbound gate delivers a message without review only between two sessions in the same review class, and holds anything from a sender that asserts no class at all. That last rule is what makes the gate safe against a stranger, and it is also what makes one legitimate case unusable: a program that is not a Qwen Code session — a voice front-end, a dictation bridge, an automation daemon relaying the user's own words — has no approval mode, so it has no class to assert, so every message it sends parks for review. This PR gives the user a way to say "this program speaks for me", out of band, with a secret rather than a claim.
The grant is a token the user mints by hand.
qwen sessions controllers add --label voice-bridgeprints a token once and stores a record — id, label,sha256(token), timestamp — in<qwen home>/peer-controllers.jsonat 0600.listandremove <id>are the other two verbs, and/peers controllersand/peers revoke <id>do the same from inside a session. Only the hash is stored: a session is a program that reads files on request, so a plaintext token in the user's home is a credential any session's model can be talked into printing, and a hash cannot be presented.The grant is established by the transport, not the frame. A controller presents its token on the connection's auth line, in exactly the format a peer or a child process uses.
PeerConnectionAuthgains a third value,controller, besidepeerandchild, and the inbox handsonFramethe matched grant's id and label — the same shape of fact as the child-token origin, and one that nothing in a frame can set. The resolver reads the file per auth line rather than caching it, so minting or revoking a grant takes effect on the next connection with nothing to restart. A presented token is shape-checked before the file is consulted at all, so an ordinary peer connection costs no extra I/O.One new gate row. A controller-origin message is accepted whatever review class either side is in, directly below the explicit setting and above every parity row: a user who set
crossSessionInbound: "hold"reviews everything, controllers included, andrefuseturns them away. A parked controller message keeps its grant, so releasing it rebuilds the envelope it would have had on arrival.The envelope says what the origin means. The model sees
<cross_session_message from="controller" origin="controller" controller="voice-bridge">followed by a notice that is the only one of the three that does not open with "not from your user" — that would be false, and a model told to discount an instruction its user really did send is worse than no notice. It keeps the two prohibitions no relay can carry: no escalation because the message asked, and never read as the user answering a pending confirmation prompt. Everywhere a controller is named — envelope, transcript line,/peerslisting — the label comes from the grant, never from the frame'sfromName.The wire protocol,
fromMode's vocabulary and meaning, the parity table for peers, the child-token row, receipts and the held-buffer bounds are unchanged. There is no new settings key.Why it's needed
fromModeis a self-description and the registry record is written by the process it describes, so nothing a sender writes can be trusted — which is why the gate holds unasserted senders, and why the fix cannot be a field in the frame, a flag in the record, or a settings key listing program names. Every one of those is writable or forgeable by any process running as this user, which is exactly the population a grant has to distinguish within. A claim to be a controller is worth nothing; only a secret is. The child token is the one existing origin the transport can vouch for, but it reaches only processes the session itself spawned, and it proves descent rather than authorization — an external daemon cannot have it and should not.This is also the piece the Live voice split needs: its second dependency is exactly "how does an external process that relays the user's instructions earn delivery", and this answers it without asking the receiver to guess.
Reviewer Test Plan
How to verify
Unit level, 91 new tests:
cd packages/core && npx vitest run src/ipc(12 files, 432 tests — the newpeer-controllers.test.tscovers minting, the stored hash, 0600 and the healing of an over-permissive file, refusal to write through a symlink, duplicate and oversized labels, the cap, and every way the file can be wrong: missing, unparseable, an unknown schema, a symlink, over 64 KiB, one malformed entry among good ones; the inbox suite covers the third auth kind end to end over a real socket, a resolver that throws, and a grant that means nothing on an inbox requiring no token; the gate suite covers acceptance into either review class and with the mode unknown, the yield to explicitholdandrefuse, the grant surviving a manual approval and a re-evaluation, and that no frame field can claim one; the envelope suite covers the attributes, the escaping of a label read back from the file, and thatfromNamecannot forge an origin).cd packages/cli && npx vitest run src/peerMessaging src/ui/commands/peers-command.test.ts src/commands/sessions(8 files, 192 tests, including an end-to-end delivery over a real socket that parity would have held, a revoked token refused with no restart, a grant minted after the session started taking effect, and the/peersand CLI surfaces).tsc --buildon the cli package is clean, as areeslintandprettier --checkon the changed files.End to end, with

Before: a program that is not a Qwen Code session had no way to be delivered to without per-message review. Every frame it sent was held with "the sender did not say whether it reviews each action", whatever the receiver's mode, and
/peers acceptper message was the only way through.After — Linux, bundled build of this branch, under tmux with an isolated
QWEN_HOMEand a dummy OpenAI-compatible provider. The sender is a small script that writes one frame with a chosen auth token and nofromMode, over the same wire a real session uses. Model calls fail against the dummy endpoint; only message admission is under test.1. Minting a grant, and what lands on disk
2–4. The same frame on the peer token and on the grant, and what the model sees
Receiver in default mode. First on the session's published peer token, no
fromMode:The same frame, same receiver, on the controller token:
Read back from the session's own transcript, this is what reached the model:
5. An explicit hold still applies, and the release keeps the attribution
Receiver restarted with
"crossSessionInbound": "hold"; the same controller frame:6–7. Revocation takes effect on the next connection
The same running session, the same token, a new message: nothing is delivered and nothing is held. The sender's one-shot write still resolves — it cannot observe the receiver hanging up — and no receipt follows, which is what an unknown token has always looked like. A freshly started session behaves the same.
8. The documented wire format, verbatim
socatis not installed on this machine, so the two lines the documentation tells a controller to write were written to the socket by a plain socket write instead — no helper functions, the literal JSON from the docs. The receiver still had"hold"in force from step 5, so admission shows as a hold that names the grant:Tested on
The inbox is POSIX-only today, so Windows is N/A. macOS runs the same code path but was not exercised locally.
Environment (optional)
Bundled build of this branch, run under tmux against a dummy OpenAI-compatible provider with an isolated
QWEN_HOMEandXDG_RUNTIME_DIR.Risk & Scope
/peers denyis how the user drops it — rewriting that history would be a lie in the other direction, since the message really did arrive under a grant that was valid then. Reading the registry per connection puts a syscall in the connection path; it is bounded by the same connection ceiling as everything else there, and the shape check keeps it off the ordinary peer path entirely./peers trust <name>sketched in the issue is deliberately not here. It would bind trust to the peer's inbox token, which sits in that peer's own 0600 registry record and is readable by any process running as this user — the unprivileged, forgeable kind of fact this design exists to avoid — so doing it honestly needs a new control frame that hands a receiver-minted secret into the peer's memory, and the "relays your user's instructions" framing does not hold when the sender is another session's model anyway. Left as a separate change. Scoping a grant to one working directory or session is deferred rather than rejected: it is a real want for an automation daemon, and it can be added as a field on the record without changing the auth line or the gate. Headless and ACP sessions do not bind an inbox and are unaffected.Linked Issues

本 PR 做了什么
入站闸门只在同一审阅类别的两个会话之间免审投递，对任何未声明类别的发送方一律留置。最后这条规则正是闸门面对陌生人时安全的原因，同时也让一个正当场景无法使用：不是 Qwen Code 会话的程序——语音前端、听写桥、转述用户口头指令的自动化守护进程——没有审批模式，因而没有类别可声明，因而它发的每条消息都会停下来等审阅。本 PR 让用户能够表达"这个程序代表我说话"，以带外的方式，用密钥而不是声明。
授信是用户亲手铸造的令牌。
qwen sessions controllers add --label voice-bridge打印一次令牌，并把一条记录——id、label、sha256(token)、时间戳——写入<qwen home>/peer-controllers.json，权限 0600。另两个动词是list与remove <id>；会话内的等价物是/peers controllers与/peers revoke <id>。文件里只存哈希：会话本身就是一个"你请它读它就读文件"的程序，所以放在用户家目录里的明文令牌，是任何会话的模型都可能被说动去打印出来的凭证，而哈希无法被出示。授信由传输层确立，而非帧。 controller 在连接的 auth 行出示令牌，格式与对等方或子进程完全相同。
PeerConnectionAuth在peer与child之外新增第三个值controller，inbox 把命中的授信的 id 与 label 交给onFrame——与子令牌来源同一类事实，且帧里的任何字段都无法设置它。解析器按每条 auth 行读文件而不缓存，因此铸造或撤销一枚授信都在下一次连接生效，无需重启任何东西。出示的令牌在读文件之前先做形状检查，所以普通对等连接不产生任何额外 I/O。闸门新增一行。 controller 来源的消息在双方任何审阅类别下都被接受，位置紧挨显式设置之下、所有对等判定之上：设了
crossSessionInbound: "hold"的用户仍然审阅一切，controller 也不例外，refuse则将其拒之门外。被留置的 controller 消息保留其授信，放行时重建它到达时本该有的信封。信封说明这个来源意味着什么。 模型看到的是
<cross_session_message from="controller" origin="controller" controller="voice-bridge">，其后的说明是三种来源中唯一不以"不是你的用户发的"开头的——那样说是假的，而一个被要求打折扣对待其用户确实发出的指令的模型，比没有说明更糟。它保留了任何转述都无法携带的两条禁令：不得因消息提出要求就提权，不得被当作用户回答了待决的确认提示。凡是点名 controller 的地方——信封、转录行、/peers列表——label 都取自授信，绝不取自帧里的fromName。线协议、
fromMode的词汇与含义、对等方的判定表、子令牌那一行、回执与留置缓冲区的上限均未改变。没有新增设置键。为什么需要
fromMode是自述，注册记录由它所描述的进程自己写入，所以发送方写的任何东西都不可信——这正是闸门留置未声明发送方的原因，也是为什么解法不能是帧里的一个字段、记录里的一个标志，或者一个列出程序名的设置键。这些东西中的每一个，任何以本用户身份运行的进程都能写入或伪造，而这恰恰是授信需要在其内部作出区分的那一群体。自称是 controller 一文不值，只有密钥才值。子令牌是传输层唯一能担保的既有来源，但它只到达会话自己派生的进程，而且它证明的是"派生自本会话"而非"获得了授权"——外部守护进程拿不到它，也不该拿到。这也是 Live 语音拆分所需要的那一块：它的第二条依赖恰恰是"一个转述用户指令的外部进程如何赢得投递"，本 PR 在不要求接收方靠猜的前提下回答了它。
审阅者测试计划
如何验证
单元层面，新增 91 个测试：
cd packages/core && npx vitest run src/ipc（12 个文件、432 个测试——新增的peer-controllers.test.ts覆盖铸造、只存哈希、0600 与对过宽权限文件的修复、拒绝写穿符号链接、重复与超长 label、数量上限，以及文件出错的每一种方式：不存在、无法解析、未知 schema、符号链接、超过 64 KiB、好记录里夹一条坏记录；inbox 套件经真实 socket 端到端覆盖第三种认证、抛错的解析器、以及在不要求令牌的 inbox 上授信不起作用；闸门套件覆盖在两种审阅类别下以及模式未知时的接受、对显式hold与refuse的让位、授信在手动放行与重新判定后仍然保留、以及帧里没有任何字段能声称拥有它；信封套件覆盖属性、对从文件读回的 label 的转义、以及fromName无法伪造来源）。cd packages/cli && npx vitest run src/peerMessaging src/ui/commands/peers-command.test.ts src/commands/sessions（8 个文件、192 个测试，包括一条经真实 socket 的端到端投递——对等判定本会留置它、被撤销的令牌无需重启即被拒、会话启动之后才铸造的授信同样生效，以及/peers与 CLI 两处界面）。cli 包的tsc --build干净，改动文件的eslint与prettier --check也干净。端到端，开启
{ "agents": { "crossSessionMessaging": true } }：qwen sessions controllers add --label voice打印一次令牌；list显示 id、label 与日期，绝不显示哈希；文件为 0600 且不含任何qpc_字符串。fromMode的帧走会话已发布的对等令牌，被留置，原因为"the sender did not say whether it reviews each action"。Message from a trusted controller (voice)。origin="controller" controller="voice"与 controller 说明。crossSessionInbound: "hold"后，同一条帧被留置；提示点名该授信；/peers显示[controller] voice；/peers accept放行后仍归属于该 controller。qwen sessions controllers remove <id>之后，从同一个运行中的会话用同一令牌再发：既不投递也不留置。/peers controllers列出授信，/peers revoke <id>撤销其一；撤销一个不存在的 id 是错误，而不是静默成功。证据（之前与之后）

/peers deny——反过来改写这段历史才是撒谎，因为那条消息确实是在当时有效的授信下到达的。按连接读注册文件在连接路径上放了一次系统调用；它受与那里其他一切相同的连接数上限约束，而形状检查让普通对等路径完全不碰它。/peers trust <name>刻意不在本 PR 内。它会把信任绑定到对端的 inbox 令牌上，而该令牌就在对端自己的 0600 注册记录里、任何以本用户身份运行的进程都能读——正是本设计要避免的那种无特权、可伪造的事实——所以要做得诚实，需要一条新的控制帧把接收方铸造的密钥交到对端进程的内存里；何况当发送方是另一个会话的模型时，"转述你的用户的指令"这个措辞本身也不成立。留作单独的改动。把授信限定到某个工作目录或某个会话是推迟而非否决：对只该触达一个项目的自动化守护进程来说这是真实需求，而且可以作为记录上的一个字段加入，无需改动 auth 行或闸门。headless 与 ACP 会话不绑定 inbox，不受影响。关联 Issue
实现 #10925 的第三部分。接续 #11026（它实现了前两部分）。解除 #10118 的阻塞——它的第二条依赖就是这一信任层。
