Proposal discussion: #12180 (opened per the contributing guide; implementation here is a concrete reference).

Snoozing a thread only hides it from the inbox; the provider session keeps running with the same footprint. Settle frees the session but means "done", so there is no middle state for parking work on RAM-constrained devices.

This adds Pause session to the thread menu (web sidebar row, chat header, mobile v2 rows). It dispatches the existing thread.session.stop command, so no contract change and all providers support it. The next message recreates the session server-side. Blocked mid-turn like archive (interrupt first). Paused threads show a muted Paused pill/label on web and mobile.

Verified: focused unit tests for the touched files pass (130 tests), tsc clean in client-runtime/web/mobile.

GUI footprint is minimal: one menu item through the existing thread-menu path, plus a muted status pill/label following the existing status conventions. No new surfaces, no motion — so no screenshots attached.

Closes discussions

Closes #12938

Summary by CodeRabbit

  • New Features

    • Added the ability to pause eligible sessions from web and mobile thread menus.
    • Paused sessions now display a clear “Paused” status.
    • Pause is unavailable while a session is starting, actively running, already paused, or settled.
    • Running turns must be interrupted before pausing.
  • Bug Fixes

    • Failed stopped sessions are correctly shown as failed rather than paused.
  • Documentation

    • Updated guidance on when sessions can be paused.

Snoozing a thread only hides it from the inbox; the provider session keeps
running with the same footprint. Settle frees the session but means "done".
This adds the middle state: Pause session stops the provider subprocess
while the thread stays active, and the next message recreates the session
server-side (ensureSessionForThread treats stopped as absent).

No contract change: pause dispatches the existing thread.session.stop
command, so all providers support it. Blocked mid-turn like archive
(interrupt first). Paused threads show a muted Paused pill/label on web
and mobile; resume is sending the next message.

🟠 High state/threadSettled.ts:335

The pause path can terminate a newly started turn without interrupting it: canPauseSession allows starting sessions, and its client-side snapshot can become stale before attemptPauseSession sends the unconditional thread.session.stop. Because the server accepts that stop and tears down the resolved session, reject starting sessions and enforce an idle-only or session/turn-guarded pause atomically on the server.

Also found in 2 other location(s)

apps/web/src/components/Sidebar.tsx:4171

The pause eligibility check is only a stale client snapshot. After the context menu is opened (or from another client) a new turn can start before this handler calls attemptPauseSession; pauseThreadSession then sends an unconditional thread.session.stop. The server decider only protects onlyIfSettled stops (apps/server/src/orchestration/decider.ts:1828-1847), so this pauses/kills the newly running turn despite the feature's stated mid-turn guard. Make the stop conditional on the session/turn state server-side (or add a pause-specific guarded command) so a concurrent turn cannot be interrupted.

apps/web/src/hooks/useThreadActions.ts:747

canPauseSession returns true for a starting session because it only rejects running sessions with an active turn. starting is a real pending-turn state with activeTurnId: null (the server creates it before starting a provider turn), and the thread.session.stop command is unconditional: the decider explicitly accepts it for starting sessions and the reactor tears down the provider session. Thus selecting Pause during the startup window silently cancels the message/turn even though the feature promises to require an interrupt first. Reject starting (and preferably have the server enforce an idle-only pause command/condition) before dispatching the stop.

The pull request adds session pause support to web and mobile thread lists. It defines pause-state predicates, stops eligible provider sessions, adds pause menu actions and paused status indicators, wires mobile callbacks, adds tests, and documents pause requirements.

🟡 Minor · Show the paused status in slim rows. · Sidebar.tsx:1647-1685

apps/web/src/components/Sidebar.tsx:1647-1685
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Show the paused status in slim rows.

A settled thread can have an idle session that passes canPauseSession. Pausing dispatches stopThreadSession without un-settling the thread, so settledOverride === "settled" keeps it in the settled section and the slim renderer after the session becomes stopped.

This slim slot renders only a wake label, Woke, or a timestamp. The Paused label and PauseIcon are rendered only in the card branch through topStatus. Render the muted paused label or icon in the slim-row path.

Include Pause session in settled slim-row menus.

Settled threads render as variant: "slim" even when canPauseSession(thread) is true. The web action contract also offers Pause when canPauseNow is true, regardless of settlement. Mobile currently excludes pauseMenuItems from slimMenuActions, and !canUnsettle prevents those items from being populated. Removing only that guard is insufficient. Add pauseMenuItems to slimMenuActions and remove the row-shape guard. Otherwise, users must un-settle the thread before they can stop its provider session and free its process memory.

Interrupt the active turn before pausing.

Line 335 rejects a running session with activeTurnId. Web and mobile actions then return a blocked error and never dispatch thread.session.stop. This requires the user to interrupt manually.

The PR objective requires a pause during a turn to interrupt it first. Implement the interrupt-then-stop sequence for this state.

- Stopped sessions carrying lastError read as failed, never paused
  (web pill gating and mobile row status).
- Reject starting sessions client-side: a turn may be adopting mid-stop.
- Drop the Sidebar success toast: dispatch only confirms the stop request
  was accepted, so the arriving Paused pill is the confirmation.
- Hide Pause on settled threads: settle cleanup already parks the session,
  and settled slim rows have no paused state.

…ssions and save RAM

From pingdotgg#12172 by @OmarAlaaeldein. The sidebar keeps the fork's
Failed status ahead of the new Paused one.

Its sidebar "Paused" status matched every cleanly stopped session, so
threads closed by the idle reaper, settling or an app restart all read as
paused. The idle reaper and settle already free provider memory, so the
manual action added little. Removes the menu item, status, docs, README row
and guard line.

This reverts commit 03eb9da.

🟡 Minor · Offer Pause session for snoozed threads. · thread-list-v2-items.tsx:677-720

apps/mobile/src/features/threads/thread-list-v2-items.tsx:677-720
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Offer Pause session for snoozed threads.

When canPauseSession(thread) is true for a snoozed row, mobile excludes Pause session and the snoozed menu does not include pauseMenuItems. This prevents users from pausing the retained provider session until they wake the thread. The web menu does not apply this snoozed-row exclusion.

Remove the exclusion and include pauseMenuItems in snoozedMenuActions.

Proposed fix
-      canPauseSession(thread) &amp;&amp; !snoozedRow &amp;&amp; !canUnsettle
+      canPauseSession(thread) &amp;&amp; !canUnsettle
const snoozedMenuActions = useMemo&lt;MenuAction[]&gt;(
  () =&gt; [
    SNOOZED_MENU_ACTIONS[0]!,
    ...pauseMenuItems,
    ...titleMenuItems,
    SNOOZED_MENU_ACTIONS[1]!,
  ],
  [pauseMenuItems, titleMenuItems],
);

Note

This comment is posted by Julius' dot

The PR explicitly omits screenshots despite adding Pause session menus and a Paused status on web and mobile. The verification rule applies even to a small UI addition. Please attach before/after images and a short pause/resume recording showing the observed session state, then request reconsideration.
