Pressing Escape in an inline editor while an agent is running triggers thread.stop instead of cancelling the edit. Because !terminalFocus is true for these inputs, ChatView's capture-phase handler intercepts the new global binding before the editor's Escape handler; add a focused-editable guard before dispatching thread.stop.

When ComposerStashMenu is open during a running turn, pressing Escape interrupts the thread instead of only dismissing the menu. Its data-composer-drawer-layer portal is not matched by TYPE_TO_FOCUS_FLOATING_LAYER_SELECTOR, so this guard falls through to onInterrupt(); include the composer drawer layer in that selector.

🟠 High power/DesktopKeepAwake.ts:499
Concurrent setEnabled calls can leave the service reporting enabled while the blocker or Windows power state is inconsistent: two enables can overwrite currentId, leaking the first blocker, and an enable can resume after a concurrent disable has cleared savedSettings, leaving no power protection for the stored blocker. Serialize the entire enable/disable transition, including applyExecutionState, blocker start/stop, and power-setting restore, with a mutex or semaphore.

Startup recovery misses recovery files written under the configured userDataPath, so after a crash the previous power settings remain forced awake. recoverPreviousSession calls getRecoveryFile() while make() is building the layer, before DesktopApp calls app.setPath("userData", userDataPath), and therefore reads Electron’s default path instead of the path used later by writeRecoveryFile. Defer recovery until the application path is configured or pass the resolved path into this service.

If Windows or the user switches power plans while Keep Awake is enabled, disabling it restores the saved values into the new SCHEME_CURRENT plan, while the originally active plan remains forced to never sleep/hibernate and ignore lid close. The queries, mutations, and restoration all use the alias SCHEME_CURRENT rather than the scheme GUID active at enable time; capture that GUID and use it throughout, or explicitly restore the original scheme when the plan changes.

ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a substantial Keep Awake capability that mutates OS power settings and introduces new IPC, native, persistence, and UI paths, while also changing the default Escape keybinding. Unresolved high-severity risks remain around Escape handling and power-state lifecycle/recovery, so the changes warrant human review. Not approved because:

💡 Result:
<search_synthesis>
There are no commands named powercfg /getacvalueindex or powercfg /getdcvalueindex in the Windows powercfg utility [1][2][3]. These commands do not exist, and consequently, there is no documentation for their output format [1][4]. To retrieve the current AC or DC power setting index values, you must use the powercfg /query (or /q) command [1][5]. This command outputs the configuration of power schemes, including the current AC and DC power setting indices for each setting [5]. The output of powercfg /query is a text-based list of power settings, subgroups, and schemes [5]. For each specific power setting, the output includes lines formatted as follows [5]: Current AC Power Setting Index: 0x00000064 Current DC Power Setting Index: 0x00000032 These values are displayed in hexadecimal notation [5]. To programmatically extract these values, users typically parse the output of powercfg /query using tools like findstr, PowerShell, or other text-processing utilities [6]. If you are developing an application and need to retrieve these values programmatically, you should use the Windows API functions PowerReadACValueIndex and PowerReadDCValueIndex from the powrprof.h header, rather than attempting to parse command-line output [7][8]. These functions return the values directly as DWORDs [7].

Use a supported read operation and validate all original values before changing power settings.
/getacvalueindex and /getdcvalueindex are not supported powercfg options. defaultRunPowercfg converts their failures to empty strings, so parseFirstHex returns undefined for all six values. The enable path still calls forcePowerSettings, which sets all six values to 0. restoreSetting then skips every restore because no original value is defined.
Use PowerReadACValueIndex and PowerReadDCValueIndex, or parse only the Current AC Power Setting Index and Current DC Power Setting Index fields from /query output. Do not pass /query output directly to parseFirstHex, because it contains earlier hexadecimal fields. Abort before persisting or forcing settings unless all six values are available.

Persist the original power-scheme identifier.
Every read, force, and restore operation targets SCHEME_CURRENT. If the user changes the active plan while Keep Awake is enabled, the reassert loop modifies the new plan. Disable then writes the old plan's values into the new plan and leaves the old plan modified.
Save the active scheme GUID with KeepAwakeSavedSettings. Use that GUID for all subsequent force and restore commands.

Retain recovery data until restoration succeeds.
getAndSet(savedSettings, null) clears the in-memory values before restoration. defaultRunPowercfg suppresses each command failure. The code then deletes the recovery file unconditionally.
If restoration fails, the forced settings remain and the service loses its only recovery data. Return command failures and clear the saved values only after all restore commands and /setactive succeed.

Serialize reassertion with disable.
The loop can read non-null savedSettings immediately before disable restores the settings and deletes the recovery file. The loop can then run forcePowerSettings after disable completes.
This race leaves the service disabled while Windows remains forced awake without recovery data. Use one mutex or semaphore for reassertion, enable, disable, and finalization.

Adds two small features in one branch (two commits, one concern each).\n\nKeep Awake (commit 1): remote agent work dies when the host sleeps or the lid closes. Settings → Connections → This-machine now has a Keep Awake toggle. On Windows it holds prevent-display-sleep plus SetThreadExecutionState (SYSTEM+DISPLAY+AWAYMODE) and forces lid-close to Do Nothing with sleep/hibernate timeouts at never, saving all six original values on enable and restoring them on disable, quit, or next launch after a crash (userData recovery file, 25s re-assert loop). macOS/Linux hold the display-sleep blocker only.\n\nEsc stops turn (commit 2): Esc now triggers thread.stop, the same interrupt path as the round Stop button. Dialogs and menus close first, terminal focus is ignored, and it stays remappable in Keybindings settings.\n\nVerification: typecheck clean for contracts, desktop, web and shared; targeted web unit tests pass (keybindings, settingsSearch, KeybindingsSettings logic — 198 tests). No UI screenshots yet — desktop GUI was not launched in this environment.\n\nBuilt with Muse Spark via T3 Code.
