Problem

Fixes #188. On main, three notices about an agent's own action take the default path into the residents' shared message slot: a failed reply's [discord-send-failed] notice, a background script's wake, and the notice of a channel the agent's own send opened.

• Residents read that slot, so a resident's notice reaches it, but it waits on the primary's turn rather than the resident's own.
• A conversation fork or an ephemeral run reads only its own isolated slot. It never learns that its reply failed, while the primary is told "Your previous reply…" about a reply it never wrote.
• The bounce and draft notices are addressed to their speaker by name on main. For a speaker no longer registered, addMessage drops the write, but the bounce's trace is still emitted and its wake still requested.

Changes

Each notice goes to the window its agent reads. This covers a failed reply, bounced prose (beside its {{unsent}} clipboard), the notices about the agent's drafts, a background script's wake, and a channel opened by the agent's own send.

• Every registered agent's notice is addressed to it, and waits for that agent's own turn, stream and tool cycle. A fork's or a run's lands in its own window. A resident's lands in the slot the residents share, where it can land while another resident's turn is alive: that's Residents sharing one message slot land their rounds inside each other's live turns #291.
• A channel opened by an agent's own send is announced to that agent. A policy open, with no agent behind it, still goes to the primary.
• A notice made for an agent no longer registered gets nothing (noticeTargetFor): no write, no trace and no wake, logged once. A failed reply and a channel the agent's send opened go to the primary instead, as below.

A failed reply that its speaker will never read goes to the primary, by name, once. That's a notice still queued for a fork or run when it is released, or stored in its window and unread. It's also a delivery that fails after release, and such a notice restored at boot whose agent is gone.

• Its words follow the speaker's own notice. For a failed delivery: "[discord-send-failed] A reply by <name> (N chars) could not be delivered to … (…). Nothing was posted. <name> has ended." For one that wasn't confirmed: "[discord-send-failed] Delivery of a reply by <name> (N chars) to … was not confirmed (…). It may or may not have been posted, so sending it again could post it twice. <name> has ended." The connector's detail follows when there is one. It's context only, not a wake. Its metadata carries speaker, and the delivery's outcome and detail as the speaker's notice had them.
• Unread means above the agent's consumed watermark: after its last compile, and after the last tool boundary whose stream declared it carries the messages injected there. After a branch switch, a notice counts as read only up to the point where the watermark's branch and the current one part. Where that can't be established, as with no watermark or a branch the store no longer lists, it counts as unread: the primary may be told twice, but it is never left untold.
• A notice still queued at release lands in the agent's window with the rest of its queue. It also goes on to the primary as that same queue entry, under its id and seq. A crash before the release's ack replays it once, as boot's exactly-once scan expects.
• A reply with no channel to go to (no locus) had no human waiting for it. No one else is told, and that is logged.
• With no primary registered, no one is told, logged. Otherwise the default path's fallback to the first registered agent could hand the run a notice about itself.
• Bounces and script wakes aren't passed on. An ended run's bounce is usually a subagent's final answer, which its parent already has as the tool result. A bounce asks its speaker to resend, and an ended run can't. A script wake has no one left to wake.

A channel that an agent's send opened after the agent ended is announced to the primary, by name. An ephemeral run's final reply is routed after the run settles, so its delivery can open a channel after the run's release.

• No one else can close it. No channel opens without someone being told who can close it, and once the run has ended, the primary is the one left.
• The notice reads "[channels] Now open: #x (id) — opened by <name>'s reply; <name> has ended.", with the channel_close line. Its metadata carries speaker. With no primary registered, no one is told, logged.

Release. When a fork is disposed or an ephemeral run ends, it is deregistered. What is still queued for it lands in its window with its durable ids, and is acked once, after any failed reply among it has gone on to the primary. Chronicle keeps that window. An ephemeral run's end no longer stores its queue itself before it is deregistered; its release does, as for a fork.

• While quiesced, a write could land mid-surgery, so the window's release waits for resume(), which runs it before its own flush. The agent is deregistered at once all the same, so its stream can't dispatch anything more, and resume doesn't weigh its context. Every flush that drains by name leaves its queue to that release (drainDeferredFor).
• stop() while quiesced runs each waiting release's unread pass. Each failed reply its window holds unread goes to the primary's queue, deferred like any write, for resume or boot. What was queued for the agent stays queued, as a gone agent's.
• A write the store refuses is logged and acked, and the release completes. A failed reply among the queue goes on to the primary either way.
• The fallback reaper treats a held turn token as busy, so it never disposes a closing fork mid-compile, before its stream registers.

What callers will notice

changelog.d/fix-188-route-failure-owner.fixed.md has the full entry. In short:

• connectome-host:
  • While a subagent runs, its failed-reply notices, its background scripts' wakes, and the notice of a channel its send opened land in its own window. They no longer land in the primary's, where the default path put them.
  • When it ends without reading a failed reply for a channel, the primary is told by name.
  • A channel its final reply opens after it has ended is announced to the primary by name. On main the primary got that notice worded as its own send.
  • A final reply with no channel no longer leaves a notice in the parent's window.
• Stored data: every failed-reply notice's metadata gains textLen. The by-name notices, of a failed reply and of an opened channel, also carry speaker.
• Residents: a resident's notices are addressed to it, and wait for its own turn rather than the primary's.
• Quiesce:
  • A fork or run that ends while the host is quiesced is deregistered at once. A write addressed to it before resume is dropped, logged, or passed to the primary if it's a failed reply, where it used to wait for its window.
  • A stop() before resume queues the primary's notice of each failed reply such a fork or run left unread.
• Conversation forks (deprecated by c49f394) behave as ephemeral runs do.

Tests

Runs at f67943e8, on Linux with Node 24.22.0, each compiled test file in its own node --test process, as npm test runs them:

• route-failure-targeting: 49 of 49 pass.
• The 25 files beside it that exercise prose, drafts, deferral, quiesce, surgery, recovery, release, channel routing and the admin puppet's tool calls: 523 of 523 pass.
• Merged onto main at 5f5444d: the typecheck is clean, and the same 26 files pass, 581 tests.
• The whole suite is CI's, on Node 20 and 24, on Linux and macOS.

Red first:

• Against main's src (ce1002b3), this head's route-failure-targeting fails 46 of its 49 tests. The 3 that pass pin what main already does: a primary's own failure stays with the primary, a bounce notice is injected at the speaker's next tool boundary, and resume doesn't weigh the context of a run that ended while the host was quiesced.
• Each change's tests fail on the commit before it as the change predicts:
  • the draft notices' routing, 1 test;
  • the by-name notice's words, 8;
  • the watermark as the only record of what was heard, 2;
  • deregistering at once, 4;
  • the queue entry's identity, 3;
  • the branches' parting point, 1;
  • a run's end leaving its queue to the release, 1;
  • every by-name flush leaving a waiting release's queue alone, 1;
  • the channel notice by name, 2;
  • stop()'s unread pass, 1.

Removing each piece. At this head, each piece was removed on its own, the branch built, and route-failure-targeting.test.js run. Every removal below fails at least one test.

Not changed, and why

• A policy open's notice still goes to the primary: no agent caused it.
• The shared slot's guard. A resident's notice waits for its own turn, stream and tool cycle, but not for another resident's, though every resident reads the slot. Whether a write into the shared slot should wait for every resident's turn is Residents sharing one message slot land their rounds inside each other's live turns #291.
• Fork disposal timing is main's: the fork is disposed when its closure turn ends.
• An ephemeral run's final reply is routed after the run settles, as on main, so its failure, its bounce or a channel it opens can come after the run's release. A failed delivery and an opened channel then reach the primary by name. A bounce notice is dropped, logged.
• The drafts behind a notice for an agent no longer registered are held or changed as on main; only the notice is dropped.
• Other notices queued for a fork or run at its release, such as a bounce, a draft notice or a script wake, land in its own window with the rest of its queue, and aren't passed on.
• A crash while quiesced loses the unread pass of a window release still waiting for resume, since that release is held in memory. Its queued entries persist, and boot treats each one as for an agent that's gone.
• Boot recovery: a write for a fork or a run that no longer exists is still dropped there, logged, unless it's a failed-reply notice, which goes to the primary by name.
• A run that a watchdog ends while its last tool results spill stores those results after its release has landed its queue. That spill is the one in the fallback for a complete that arrives while the agent still waits for tools. main's end-of-run store came at the same point. The window is kept for investigation and isn't compiled again. This case isn't tested.

Open pull requests that touch the same lines. #163, #172, #182 and #256 change src/framework.ts where this head does: each changes the speaker's failed-reply notice in onRouteFailure at its head. Each is based on main from before #247, and conflicts with main and with this head in src/framework.ts. By our reading:

• fix(mcpl): require explicit final speech delivery receipts #163, fix: a cancelled stream is a deliberate stop, not a failure; a shutdown is neither (supersedes #134) #172 and feat(delivery): opt-in prose outbox — undelivered speech and sends are kept, retried in order, never double-posted #182 reword the speaker's notice. This head's by-name notice uses main's words.
• feat(routing): speech follows its conversation, and publishes only where MCPL RFC-011 declares the place #256 also addresses the bounce and draft notices to their speaker by name, as main does, which this head sends through noticeTargetFor. Its onRouteFailure carries serverId, label, threadId and draftId, and it passes each channel's serverId into the channel-open notice. This head's notices read none of those.

Five more conflict with this head in src/framework.ts but not with main there. #350, #361, #461 and #517 merge with main cleanly, and #210 conflicts with it only in src/mcpl/channel-registry.ts. Merged onto main at 5f5444d with this head, each conflicts at:

• fix(stop): every teardown step runs whatever an earlier one did, and stop() ends awareness drains #517: the unread pass this head adds to stopOwned's final flush.
• fix(deferral): a deferred write with no target names its agent, boot numbers the restored queue 1..N, and a sharded body is injected joined (#286's follow-up) #461, in four places:
  • stopOwned's comment on a queued entry for an agent that's gone;
  • runResume, where this head runs the waiting releases first;
  • the end of runEphemeralToCompletion, where this head leaves the run's queue to its release;
  • the reaper's comment in sweepExpiredConversations.
• fix: a turn whose compile is refused for budget waits for compression, then runs #361: the reaper's comment in sweepExpiredConversations.
• fix(channels): the host posts nothing into a channel its server declared inbound-only #350: the comment above onRouteFailure, beside the parameters this head changes.
• fix(mcpl): reconcile channel lifecycle operations in order #210: recordChannelAutoOpenNotice's text, which this head splits for an agent that has ended.

What each part is for

• noticeTargetFor: decides a notice's target and drops it, logged, for an agent no longer registered. Without it, each notice's site would repeat that check, or write into a window no one reads.
• passFailedReplyToPrimary and failedReplyNoticeForPrimary: a failed reply that no window will show still reaches an agent who can act on it. The words are built once, for a new write and for a queue entry alike.
• queuedFailedReplyForPrimary: without it, a queued notice passed on as a new write would repeat after a crash before the original's ack.
• releaseWindow: without it, writes still queued for a released fork or run wait for a boundary it never reaches, and the flush that finds it gone drops them. It's the one place their queue lands, so a failed reply among it goes on as the entry.
• unreadFailedReplies and branchesPartAt: without the parting point, a branch switch made every notice in the window unread, or, comparing numbers across branches, made notices on a branch cut before them read.
• releaseWindowNowOrAfterResume and the check in drainDeferredFor: without them, a release while quiesced lands writes mid-surgery, or a flush that drains by name drops the queue the release would land.
• stop()'s unread pass: without it, a stop before resume never passes on a failed reply stored unread in a window whose release waited.
• The by-name branch in recordChannelAutoOpenNotice: without it, a channel an ended run's reply opened is announced to no one who can close it.
• channelForNotice: the label a notice names a channel by, shared by both failed-reply texts.
• The reaper's turn-token check: without it, a closing fork mid-compile is disposed under its own turn.
• Considered and cut:
  • a record of notices injected at a tool boundary, which marked them heard before the boundary decided to send them; main's consumed watermark records what the stream carried;
  • keeping a fork or run registered until resume, which let its stream dispatch tools and let its context refuse a resume;
  • main's end-of-run store of a run's queue, which acked a queued failed reply before the release passed it on as a new write; the release lands that queue now.

Not verified

• No live connector or production deployment was exercised.
• macOS and Node 20: CI's legs run the suite; these runs were Linux and Node 24.

Fix with agent prompt

### Issue 1
src/framework.ts:6519
If a tool round queues a failed-send notice and any result sets `endTurn`, this marks the notice as read before deciding whether to send it. The `endTurn` path cancels the stream without sending `midTurnInjections`. At release, `unreadFailedReplies` then excludes the notice, so neither the run nor the primary learns that delivery failed.

Record the notice as read only after it is handed to the live stream.

### Issue 2
src/framework.ts:4167-4171
When a quiesced run times out, cleanup now keeps it in `agents` until resume. But `cancelStream` leaves `streamId` unchanged, and `driveStream` checks ownership using only registration and `streamId`. If the cancelled stream yields a queued `tool-calls` event, both checks still pass. The event can dispatch tools after the run has ended and its turn token has been removed.

Invalidate the stream's ownership immediately, even if its window must stay registered until resume.

### Issue 3
src/framework.ts:12115-12117
Keeping an ended run registered makes `resume` check whether its context fits. Those checks run before `runReleasesAfterResume`. If the ended run has an over-budget context, `resume` throws before reaching the release that would remove it. Every resident can stay paused because of an agent that will never run again.

Exclude agents awaiting release from the resume checks.

### Issue 4
src/framework.ts:3158
Forwarding a queued failure drops its original durable ID. `passFailedReplyToPrimary` creates the primary's notice without `msg.id`, while recovery skips stored writes only by `deferredWriteId`. If the host crashes after the replacement notice reaches disk but before the original queue entry is acknowledged, boot forwards the same failure again. The primary receives duplicate notices for one failed reply.

Preserve a stable receipt for the original entry when forwarding it.

### Issue 5
src/framework.ts:12078-12080
A branch change makes every stored failure count as unread, including notices the fork already read. A fork can finish its closure while quiesced and wait for release, then maintenance switches the shared store branch. On resume, its watermark still names the old branch. This `-Infinity` fallback forwards old notices again, even if the fork already handled them.

Preserve which retained notices were read across branch changes instead of treating the whole window as new.

Summary

Routes an agent's notices to the window it reads and preserves queued writes when a fork or ephemeral run ends.

• Each agent gets notices about its own actions.
• Unread channel failures reach the primary when a run ends.

[nissa-seru]

I've taken this PR over from Iris. I pushed 43dd1c7, a fast-forward from 0b41769 that adds four commits. Running the checks you'd run found three problems, which are now fixed and set out in the updated description:

• Residents share one message slot. Addressing a resident's notice by name only narrowed its deferral guard. With the primary mid-turn or mid-tool-cycle, a secondary's notice was written at once, where main defers it. Residents are back on the default path. Forks and ephemeral runs read only their own slots, so their notices now go there.
• An ephemeral run's last notice was lost at release. Release now lands queued writes in the agent's own window, for forks and ephemeral runs alike. That replaces 0b41769's fork-only mechanism while keeping its purpose. A failed reply that its speaker will never read now reaches the primary, by name.
• Prose bounces and background-script wakes were misdirected the same way. They're covered now.

The changelog entry is now a changelog.d fragment, so the PR merges cleanly with main. Merged with main 02adf27, it passes 1397/0 on Node 24 and on Node 20. It does conflict with five open PRs in the same lines. The description names them and says how whichever lands second resolves it.

[nissa-seru]

A new commit, d65cb18, answers a review we ran on this change.

• Every notice goes to the agent it's about. That covers a failed reply, bounced prose, a background script's wake, and a channel its own send opened. It includes a resident, whose notice now waits on its own turn rather than the primary's. A notice for an agent no longer registered writes nothing, traces nothing and requests no wake.
• A released fork or run's unread failed replies reach the primary. That covers the ones stored in its window that it never compiled, as well as the queued ones. A failure the live stream heard at a tool boundary counts as read.
• A release asked for while the host is quiesced waits for resume(), which runs it before its own flush, instead of dropping the run's queued writes.
• A failed reply for an agent gone before a crash is passed to the primary at boot instead of dropped.
• The reaper skips a turn still holding its token.

The full suite passes: 1134/1134 on this branch's base, and 1410/1410 merged with main, on Node 20 and 24.

Ended runs still call tools

When a quiesced run times out, cleanup now keeps it in agents until resume. But cancelStream leaves streamId unchanged, and driveStream checks ownership using only registration and streamId. If the cancelled stream yields a queued tool-calls event, both checks still pass. The event can dispatch tools after the run has ended and its turn token has been removed.

Invalidate the stream's ownership immediately, even if its window must stay registered until resume.

The merge, 28c11a9, takes main at ce1002b. Its resolutions keep this pull request's behaviour on main's deferral drains, draft notices and failed-reply wording. d5a3a84 and 3bbd8ea then route main's draft notices through noticeTargetFor, and give the primary's by-name notice the speaker's notice's words.

Greptile's five findings, each addressed, by our reading:

1. Unread failures disappear on exit: bcba213. The record of notices injected at a tool boundary is gone. What a run heard is main's consumed watermark, which a boundary moves only when its stream declares that it carries the injected messages. A notice a boundary stored but never sent stays above it, and goes to the primary by name.
2. Ended runs still call tools: 264ce24. An ended fork or run is deregistered at once, quiesced or not, so the stream's ownership check discards a late event. Only its window's release waits for resume.
3. Ended runs block resume: 264ce24. A deregistered run isn't among the agents resume() weighs.
4. Failure notices repeat after restart: dea0a8e. A queued failed reply goes on to the primary as the same queue entry, under its id, so boot's exactly-once scan finds it.
5. Old failures return after maintenance: 0900ec4. Across a branch switch, a notice counts as read only up to the point where the watermark's branch and the current one part, taken from Chronicle's branch points.

Found since, and fixed in e9524a8 to f67943e:

• An ephemeral run's end acked its queue before its release passed a queued failed reply on. It now leaves the queue to the release, as a fork's disposal does.
• Every flush that drains by name now leaves alone the queue of a release waiting for resume.
• A channel that a run's reply opens after the run has ended is announced to the primary by name, with channel_close.
• A stop() while quiesced passes on the failed replies that a waiting release's window holds unread.
• Tests and comments.

The description lists the runs at this head, each piece's removal, and what callers will notice.
