feat(web): promote a subagent thread to its own sidebar row - #34441
A subagent or side-chat thread only shows under its parent, so a user cannot give it a sidebar row of its own. Promoting would be the natural way out, and there was no way back either.
Change
Adds promotedAt to the thread, with thread.promote / thread.demote commands and thread.promoted / thread.demoted events. Lineage never changes, so the parent still receives the child's result.
Lineage panel (hidden child open, not archived)
[Promote to thread] -> thread.promote -> thread.promoted (sets promotedAt)
[Move back under parent] -> thread.demote -> thread.demoted (clears promotedAt)
isListedThread(t) = isListedThreadLineage(t.lineage) || t.promotedAt != null
true -> sidebar row, command palette, composer mentions, background announcer, mobile lists
shell stream: promoted children are top-level; idle ancestors and older settled parents stay
Server: orchestrator guard (rejects archived threads and threads that already have a row), projection, shell index and shell stream.
client-runtime: promote/demote commands; list filters use isListedThread.
Web: button in the Lineage panel. Mobile lists promoted threads but has no button yet.
Scope and approval
No triaged issue or maintainer approval exists for this yet; I am asking for it here. It is one feature in one PR. Deliberately not covered: mobile button, message search of promoted threads, relay awareness for promoted threads, naming promoted side chats in the parent's delete confirmation, and an MCP tool for agents.
Verification
reproduced the missing promotion control on github/main 0318eadc32, then exercised the original pr head and final head 9d53f03152644c04231fc9f7ecb5b972437bdbbd in a real isolated linux dev server. used repo playwright with /usr/bin/google-chrome and real codex gpt-6.1-sol turns. projects, parent threads, side chats and delegated children were created through the app.
promotion/demotion changes sidebar rows, keeps transcripts and lineage, and survives reload.
a child promoted during its real turn still delivered its result to the parent. continued child turns also work.
side-chat bring back reached the parent's next codex turn. close/reopen and archive/unarchive still work.
fixed the missing promotion control in the normal side-chat pane, inherited promotion on forks, and the enabled lineage control on read-only connections. reproduced each before the fix and rechecked afterward. extended the existing fork-reset test.
inspected light/dark layouts at 1440 and 1280 pixels. two independent read-only reviews approved the final head.
main before and promoted thread after, using the same side-chat conversation:
normal side-chat pane before and after the takeover fix, with matching conversation data:
subagent and side-chat promotion, demotion and sidebar navigation (blank startup frames trimmed; animated copy of the recording; mp4 playback and seeking checked separately):
server transcript from read-only inspection of the real app's persisted events:
thread.promoted / thread.demoted persisted after web UI clicks
model = gpt-6.1-sol
lineage before promotion = lineage after promotion and demotion
live promoted child result delivered -> parent acknowledged exact result
bring back -> parent answered with the side chat's exact response
Not verified
blacksmith automated checks remain blocked: the first allocated worker's ssh endpoint timed out; its replacement stayed queued. dependency installation, focused suites and vp run check:changed were requested through blacksmith-check but have not executed. the final github head currently reports only a skipped review check, so this is not a claim of green ci.
native desktop, ios/android, other providers and remote/relay/tunnel connections were not exercised on this linux vm. the pr's explicitly deferred search/relay/mcp behavior and parent-deletion warning remain outside this pass.
Takeover verification and fixes by gpt-6.1-sol in the Codex harness.
Adds promotedAt with thread.promote/thread.demote. Lineage is unchanged, so the parent still receives the child's result. Promoted subagents are listed as top-level threads in the sidebar, palette, composer mentions and shell stream.

Disable the promotion toggle for archived subagents
When this panel is opened for an archived subagent, currentThread can come from archivedShells, but this toggle remains enabled unless another action is busy. The orchestrator rejects both promote and demote commands for archived threads, so the action always fails and only shows an error toast; hide or disable it for archived threads.
The reason will be displayed to describe this comment to others. Learn more.
Confirmed: the orchestrator rejects promote/demote on archived threads. The toggle is now hidden when the thread is archived (canPromote requires archivedAt === null).
Promotion now covers side chats too: isListedThread combines the new isListedThreadLineage with promotedAt.
Co-Authored-By: Claude Fable 5.2 <noreply@anthropic.com>
It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.
Subagent threads can now be promoted to independently listed threads and demoted to nested subagents. Promotion state is carried through commands, lifecycle events, projections, shell streams, client state, and thread visibility.
Thread types and JSON schemas add promotedAt, promotion and demotion commands and events, and helpers that classify listed threads and nested subagents.
Command handling and orchestration packages/client-runtime/src/operations/commands.ts, packages/client-runtime/src/state/threadCommands.ts, apps/server/src/orchestration-v2/Orchestrator.ts, apps/server/src/orchestration-v2/testkit/OrchestratorScenario.ts, apps/server/src/orchestration-v2/Orchestrator.control-reads.test.ts
Client commands dispatch promotion and demotion. The orchestrator rejects archived threads and threads whose lineage already has a listed row, updates promotedAt and updatedAt when state changes, and emits lifecycle events. Tests cover command outcomes.
Promotion state in projections apps/server/src/orchestration-v2/ProjectionStore.ts, packages/client-runtime/src/state/models.ts, packages/client-runtime/src/state/orchestrationV2Projection.ts, apps/server/src/relay/AgentAwarenessRelay.ts
Projection storage applies promotion events and includes promotedAt in shells and active-shell indexes. Active-subagent and older-settled queries account for promotion. Client shell presentation and projections carry promotion state. The relay treats these events as non-publishing events.
Issue 25823 — The shell-stream filtering changes address nested-thread handling, but this PR does not add batching or incremental invalidation.
Issue 27137 — Promoted subagents become eligible for command-palette discovery; the requested status filtering and working-thread prioritization remain separate.
Issue 31787 — Promotion gives a subagent its own sidebar row, but pinning behavior is not changed.

Merge Risk: Low · up to 0ca70
Promoting a subagent thread works in the sidebar and shell streams. Promoted threads will not yet show their own relay activity or alerts, which the author has marked as follow-up work. This gap is bounded, so merging is low risk.

Explanation
The description covers the Problem, Change, Scope and approval, and Verification sections in detail. It includes expected behavior, implementation scope, manual verification, screenshots, recording, unverified checks, and agent details. However, the Scope and approval section states that no triaged issue or maintainer approval exists. This is a required approval item for a feature of this scope.
Resolution
Add a link to the triaged issue or discussion and include explicit maintainer approval of the direction and scope. If the change qualifies for an exemption, explain why it is a small, focused fix of an obvious bug; the current description presents it as a new feature, so that exemption does not appear to apply.

Reject demotion of non-subagent threads.
The lineage guard applies only to thread.promote. A thread.demote command for a root thread succeeds and emits thread.demoted, even though promotedAt is already absent. In apps/server/src/orchestration-v2/ShellStream.ts, Line 420 then adds that root thread to subagentThreadIds. Lines 425–430 suppress its subsequent transcript events until the subscription restarts.
Apply the lineage guard to both commands. Extend the existing root-thread rejection test to cover demotion.

Reconcile promotion state from whole-thread events.
If resume starts before a child’s creation and compaction removed its promotion event, replay adds the child to subagentThreadIds but does not remove it on the later thread.metadata-updated. Subsequent transcript events can remain filtered, preventing shell refreshes until another event triggers one.

Early return in the relationships control (not applicable):canPromote already keeps the panel visible for hidden children, even when the relationship rows are empty.

Publish awareness for promoted threads.
A promoted child never gets its own relay activity or alerts. These events do not trigger publication, and the awareness snapshot and relay still exclude it by lineage. The shared awareness projection also ignores promotedAt. Carry promotion state through those paths and publish or clear the child on promotion and demotion. (raw.githubusercontent.com)

Ancestors of promoted children (valid, fixed): parent ids are now tracked from lineage, so an idle nested parent of a promoted child stays in trimmed snapshots. The omitIdleSubagentShells test covers it.
Demoted side chats (valid, fixed):thread.demoted only re-adds the thread to the subagent filter when it is a nested subagent; a demoted side chat keeps refreshing its shell. Covered in the shell events test.
Warn before deleting promoted side chats with their parent (deferred): deleting a parent already cascades to its side chats; promotion only makes them visible as rows. Extending both delete confirmations is UI copy beyond this PR, so I'd do it as a follow-up.
Relay awareness for promoted threads (deferred): promoted children still do not publish relay awareness, as noted in the description's "Not covered" list. Follow-up, since it touches the relay snapshot and the shared awareness projection.

Problem
A subagent or side-chat thread only shows under its parent, so a user cannot give it a sidebar row of its own. Promoting would be the natural way out, and there was no way back either.

Adds
promotedAtto the thread, withthread.promote/thread.demotecommands andthread.promoted/thread.demotedevents. Lineage never changes, so the parent still receives the child's result.isListedThread.Scope and approval
No triaged issue or maintainer approval exists for this yet; I am asking for it here. It is one feature in one PR. Deliberately not covered: mobile button, message search of promoted threads, relay awareness for promoted threads, naming promoted side chats in the parent's delete confirmation, and an MCP tool for agents.
Verification
reproduced the missing promotion control on github/main

normal side-chat pane before and after the takeover fix, with matching conversation data:
subagent and side-chat promotion, demotion and sidebar navigation (blank startup frames trimmed; animated copy of the recording; mp4 playback and seeking checked separately):

Not verified
blacksmith automated checks remain blocked: the first allocated worker's ssh endpoint timed out; its replacement stayed queued. dependency installation, focused suites and
vp run check:changedwere requested through blacksmith-check but have not executed. the final github head currently reports only a skipped review check, so this is not a claim of green ci.native desktop, ios/android, other providers and remote/relay/tunnel connections were not exercised on this linux vm. the pr's explicitly deferred search/relay/mcp behavior and parent-deletion warning remain outside this pass.
Takeover verification and fixes by gpt-6.1-sol in the Codex harness.
