 AXPress and AXSetValue are direct semantic operations. Keyboard events target the app PID. Cmd+A uses the focused editor's writable accessibility selection range where supported. Coordinate mouse input requires the target app in front; `activate_app` makes that focus change explicit and confirms it. Click/drag/scroll validate the foreground process, unchanged window geometry and the app that receives the point; the topmost window-list entry is not the click target because Notification Center and the Dock keep full-screen click-through windows. A hit on a window's own background counts as that window. Background tabs and minimized windows share bounds with the window in front, so they take no coordinate input. An action that opens UI (AXPress, AXPick, AXShowMenu) and times out while the app shows a sheet, modal or menu (`cannotComplete`) counts as dispatched; any other action that times out fails as uncertain. A menu-item press that leaves the item's own menu open with the app highlighting that item (Calendar on macOS 26) is completed with Return. Sheets, including Go to Folder and out-of-process open and save panels whose contents report no window, count as the window they are attached to. Menu item labels carry their shortcuts (for example ⇧⌘N). Some apps ignore background keyboard events. `dispatched:true,verified:false` means only dispatch succeeded; the agent must observe again to establish the outcome. No foreground activation fallback is hidden inside the helper. Native key codes currently assume the US layout for shortcuts; literal text uses Unicode events. Unsupported shortcuts fail explicitly.
 
-`type_text` and `input_sequence` target a text control (text fields and areas, terminals, combo boxes, date and time pickers, or anything with an editable text selection), or a container whose focused editor already holds keyboard focus, such as a web composer; keystrokes are sent only while focus is in a text input. `input_sequence` executes 1–32 key/text steps against one such element. It validates every step before dispatch and checks the same editor, window, and secure-input ancestry between steps. Enter can continue into another step when the same editor and window retain focus. Actual focus loss, Tab, or navigation shortcuts end the sequence before later input. Explicit `activateFirst: true` activates the target app inside the batch before input; it never enables automatic refocusing between steps. Partial execution reports completed steps and an error; callers must observe before retrying. `batch` runs 2–8 click, type_text, set_value, press_key, scroll or perform_action steps planned from one snapshot, each through its own action's checks; it stops at the first step that fails and after any step that opens or closes a window, sheet, menu or popover, reports progress the same way, and a first step that sent nothing is refused with `dispatchState: "not_started"`. Every mutation is followed by fresh state under the same authorization and queue entry; `observeAfter` optionally requests a screenshot. Observation failure is reported separately so the mutation is never replayed. The model receives a compact, bounded projection of the native snapshot; omitted nodes are reported explicitly.
