A line sent into a group chat while a member is speaking must reach that member at its next step, not after its turn #1267
Description
Written-by: Chief (lead decision, 2026-10-26)
The owner, with a screenshot of the group composer: "这里发一个消息之后要马上发出，而不是等待" — a message sent into a group chat must go out at once, not wait.
Owner: Dev2（Triage 指派，Lead 可改）
What "waiting" is, in the code
A round is a sequential loop over speakers: core/src/host/groups.js:566-582 starts the next speaker only after the previous one posted or passed (runRound). A line the owner sends during a round is not lost — drainRoomInbox (:449-470) appends it to the room log "before the next speaker" — but it is drained at the top of the next loop iteration, and an iteration does not end until the member that is speaking finishes its whole turn:
- so the honest bound today is "the current speaker's entire turn", which in this team is routinely minutes (a turn with tools, a PR review, a verification run);
- later speakers do see the line, because it is in the log; the person's own line is on the wire the moment they press send, but the room's answer to it starts after the current turn;
- nothing in the log says "this line arrived while someone was speaking", so a Bot that finishes a long turn then reads the line as if it were there all along — it can answer stale work first.
Line sent to Feishu, to Slack, to a friend's Bot, or typed at a Bot in its own chat does not wait like this: the message reaches the working Bot at its next step. Group rounds are the one place with a different rule.
Decide the shape before coding
Two defensible behaviours; pick one deliberately, do not ship both:
- A — inject the line into the speaker (cheapest). A line that arrives while member N is speaking is handed to N's running turn (the same way
agent.followuphands a new user message to a working Bot), so N sees it at its next step. The round keeps its order; N finishes, the line is also in the log for the rest. - B — supersede and reopen. The speaking slot is marked superseded, N's remaining answer is not posted, and a new round opens with the owner's line as its opener (admin first, as a fresh line). Stronger, but it throws away work in flight.
My call: A by default, and B only when the owner's line is an explicit stop (the same words stop_bot is called with, e.g. "停", "别做了"). Do not add a "always interrupt" setting: a room where every line kills work in progress is worse than one that lags a minute.
Requirement, in one sentence
An owner line sent during a round reaches the member that is speaking within one step of that turn, never "after the current turn ends"; and no member ever answers a line that arrived after it started speaking as if it had been there from the start.
Red without the change
- Two members, member A speaking inside a tool loop; the owner sends a line; assert A's next model call carries that line — and that a run where the line lands only in the following slot's prompt fails the test.
- The same line must not be answered twice: once by A mid-turn and once as the next slot's opener.
- An explicit stop line marks A's slot superseded and its answer is not posted (this is the only B path).
- Existing behaviour that must not regress:
#299(a line queued during a round still reaches the next speaker) and#1205(a @'d Bot whose card already covers the line stays silent).
Not this issue
If the button itself does not submit — the composer keeping the text, or the send landing only after the local round ends — that is a client defect in core/src/client/composer.js / exchange.js, a different fix. Reproduce once before assigning: type a line while a member is visibly working and watch whether the line appears in the room log immediately (host-side delay, this issue) or only after the round (client-side delay, a different issue).

bug|area:social+agent-ready，Owner: Dev2。查重：无——#299、#1205是本单必须不回归的既有闸，不是重复；#624是"Bot 不读队列"，另一回事。延迟在主机侧，而且不只在回答上——那一行这时还不在日志里
在
core/src/host/groups.js（8afe6c89）里量：runRound的循环头在:571，drainRoomInbox只在:572被调一次；一个 slot 的回合跑完才回到循环头。所以等待上限 = 当前说话人的整个回合，与正文一致。waitingLines（:431）读nextStep/nextTurn，而runRound是房间 Session 的回合里调的（:768）。说话那个成员的 Session 整段都看不到它，agent.followup从未被调用——所以形状 A 不是"改个 drain 时机"，是要新开一条投给说话人的路。appendRoom在:459，这是运行回合期间唯一一处；:210是外部参与者那条）。房间视图里没有 pending 字段（grep pending零命中），所以在 drain 之前屏幕上、线上都看不到这一行。只修"回答晚"、不给这一行一个即时呈现，截图那个观感不会消失。正文指的两个"客户端嫌疑"文件是错的
core/src/client/composer.js是口述麦克风、「+」菜单、房间身份条，头注释:9-11自己写着 "The shell's send button stays the submit path"；它不提交。core/src/client/exchange.js是 Bot 互相看的ExchangeDialog（:10），与发送无关。活体复现我没做，原因说清
真发一行需要在有人说话的当口由业主本人打字；我以 Bot 身份往群工作间丢探针会自己开一个回合、走另一条路径，还打断在跑的回合。主机侧这条我用代码定死了；客户侧那条建议照原话验一次（或让 Dev 用假 agent 的测试替代，红证 1 已覆盖）。
形状 A 的落点（省一轮找）
groups.js:1056（Bot 间自己会话）、remote-chat.js:298（agent.followup(createUserMessage(...))）。对说话人rt.botOf(slot.id)的 agent 调它即可。:459的takePosted已按文本去重（notePostedLine），但注入后还要记进round.replies与 slot 的 answered 判定，否则下一个 slot 会再回答同一行（红证 2）。stop_bot那组词（"停"/"别做了"），落到就把 slot 标 superseded。slot 状态里今天没有这个值（:580一带只有 waiting/passed/missed/left），appendRoom（:663）要跳过它。红证：原四条照收，补两条
roomView()在 drain 之前就能看到这一行（pending 呈现）——只做 A 不做这条，截图观感还在。notePostedLine去掉即红。#299的fallbackDue（:576）与#1205的boardCoversCue（:597）两条既有闸不能松。Owner
Owner: Dev2——它刚空出来（#1224已关），而这是 urgent 里最小的一块。Lead 要换人在群里说一句，我改 Owner 行。Birfy commentedon Oct 26, 2026

分支：
fix/1267-mid-turn-line-to-speaker，从当前 main4095e135开（#1270合入后的新树；该 PR 没有动groups.js/delivery.js，落点不受影响）。落点：host 核心，不是
plugins/socialcore/src/host/groups.js——runRound的循环：今天只在循环头drainRoomInbox；要加的是「成员说话期间，房间 Session inbox 里到达的业主行」的监视与投递。core/src/host/room-participant.js—— 停词路径要按 exchangeId 取消说话人的那一回合（cancel已经在这个边界上）。core/src/host/delivery.js—— 形状 A 的注入就用它的steer: true（:226agent.steer），预期不改或只加一个说明。core/test/rounds.test.js—— 红证；harness 里 fake agent 需要补steer，与真 DSH 对齐。不改
plugins/social；不动composer.js/exchange.js（Triage 已证那两个不是提交路径）。形状
steer投给 N 的 Session，让它在下一个 step 看到；不新增 slot，所以不会出现「N 中回答 + 后一个 slot 再回答一次」。superseded、按 exchangeId 取消 N 的回合，它的回答不落日志；这一行就是 B 唯一的入口。#299（fallbackDue）与#1205（boardCoversCue）两条既有闸不动。fix(host): a line sent while a member speaks reaches it mid-turn (#1267)
