- Line 1056: Update the background-task update logic near the length-growth
branch so a live replacement row is emitted whenever backgroundTasks.length is
non-zero, including decreases such as two tasks to one. Preserve the existing
handling for empty task lists, and add a regression case covering the two-to-one
transition.
In `@src/modules/chat/hooks/useChatMessages.ts`:
- Around line 92-93: Update the wait-row selection logic around phase and
newestLiveWaitIndex so terminal phases such as reported and expired clear or
supersede the previously active holding row. Ensure conversion does not render a
pulsing live row after the latest terminal wait row, while preserving
started/holding behavior when a newer live row exists. Add a regression test
covering holding followed by reported.

A turn that starts a Monitor, a ScheduleWakeup, a CronCreate, a TaskCreate
or a backgrounded Bash keeps its CLI process open so the work can report
back in a follow-up turn. From the browser that was invisible: the turn
reported complete, the composer went idle, and a new turn appeared on its
own minutes later. A session holding a process open looked exactly like a
session that had stopped, and a hold that expired with nothing reported
looked the same again.
Four rows, one sentence each, all of it already in the stream:
Running 2 background tasks (deploy watch, log tail)
Holding the session open for 2 background tasks · up to 30m
Background work reported in after 2m 10s
Stopped waiting for background work after 30m
The task list comes from `system` / `background_tasks_changed`, which the
SDK yields whenever the CLI's own list of outstanding work changes and
which nothing read until now. It is authoritative in a way the tool calls
are not: it survives a turn boundary, so the hold also stands while that
list is non-empty -- a turn resumed mid-wait no longer releases the process
under work an earlier turn armed.
Everything each row says is in `content`, so a client that knows nothing of
`backgroundWait` reads the sentence. A client that does draws the row, and
keeps only the newest LIVE one: they describe a state rather than a series
of events, so a pile of stale countdowns is worse than one current row. A
wait that ended stays, because that is history worth reading.
Closes siteboon#1293

The turn-end branch now holds for work the CLI still lists as well as for work this turn armed. That is the one behaviour change in this feature, so it gets a name and a test rather than living inline in a condition. Signed-off-by: Liran Funaro <liran.funaro@gmail.com>
The newest-live-wait scan looked at every row, so a wait row from a subagent could decide which of the session's own rows was current -- and suppress it. Subagent rows are folded into their container rather than drawn, so they take no part in that choice. Signed-off-by: Liran Funaro <liran.funaro@gmail.com>
Two findings from the review, both real. A row was only emitted when the task list grew, so `2 tasks → 1 task` left the newest row saying "2 background tasks" after one had finished. Any change to a non-empty list is now worth a row -- it reports what is running now, not what was armed -- while the list emptying stays what it was, the end of the wait, reported on its own. `shouldAnnounceBackgroundTasks` names the rule and is tested: armed, grown, shrunk, re-sent unchanged, swapped, and emptied. A `holding` row above the `reported` row that answered it stayed on screen, pulsing, for work that had already come back. A live row now survives only while it is the newest live row AND nothing has ended the wait since; a row that ends a wait always stays, and a live row that began after the last ending is a new wait, so it stays too. Both rules fail their new tests when reverted, which I checked. Signed-off-by: Liran Funaro <liran.funaro@gmail.com>

The problem
Since the background-work hold landed, a turn that starts a
Monitor, aScheduleWakeup, aCronCreate, aTaskCreateor a backgroundedBashkeeps its CLI process open so the work can report back in a follow-up turn. That is right, and it is invisible: the turn reports complete, the composer goes idle, and a new turn appears on its own minutes later. In between, a session holding a process open is indistinguishable from a session that stopped — and a hold that expires with nothing reported looks the same again, only the follow-up turn never comes.notifyBackgroundWorkCompletedcovers the end of it as a push notification; nothing was said in the conversation, which is where a reader looks.Server
Four rows, one sentence each:
Everything each row says is in
content, so a client that knows nothing of the newbackgroundWaitfield still reads the sentence; the field (BackgroundWaitInfo:phase,tasks,ceilingMs,until) is only how a client that does draws it.The task list comes from
system/background_tasks_changed, which the SDK yields whenever the CLI's own list of outstanding work changes, and which nothing read until now. Verified by driving both directly — SDK 0.3.263 and CLI 2.1.263 both emit it withtask_id/task_type/description.One behaviour change comes with it: the hold now also stands while that list is non-empty, not only when this turn armed something. The list survives a turn boundary, so a turn resumed mid-wait no longer releases the process under work an earlier turn armed — which is how a wait could end early and the follow-up turn go missing.
Client
normalizedToChatMessagesdraws the row and keeps only the newest live one (started,holding). These describe a state, not a series of events: keeping every one turns a single wait into a pile of stale countdowns, while keeping the newest reads as what the session is doing now. A wait that has ended (reported,expired) stays, because that is history worth reading — the expired case especially, since nothing else reports it.MessageComponentdraws it like the task-notification row beside it: a state dot (pulsing while live, amber when a hold expired, green when work reported in), the sentence, and the task list beneath it when there is more than one.Tests

New Features
Bug Fixes
Overlap with #1295. Both PRs add a branch to
normalizedToChatMessagesand a field to the same two type blocks, so whichever lands second will conflict textually (not semantically — the two branches are independent and ordered by their own guards). Say the word and I will rebase this one onto the other, or ontomainafter it merges.Overlap with #1291 (
fix(claude): hold the CLI open for backgrounded agents and workflows, opened after this one). That PR teachesstartsBackgroundWorkto scoreAgentandWorkflow; this one adds a second condition to the same hold, so it also stands while the CLI's own task list is non-empty. They close the same gap from opposite ends — the tool-call test holds across the firstresult, the list holds across a turn boundary, where the call that armed the work belongs to a turn that has already ended — and #1291 is the root-cause half. It editsDEFERRED_WORK_TOOLSwhere this PR inserts its helpers, so the two conflict textually: merge #1291 first and I will rebase this onto it.
