+Make Windows physical clicks robust to another absolute pointing device, such as a remote-desktop or virtual-machine
+viewer, that moves the cursor back after injection. Pointer placement now confirms the cursor reached the target and
+retries before pressing, element clicks inject the press and release as one coordinate-carrying batch, and pointer
+actions carry their coordinate on every press and release. Previously such a device could redirect the press to its
+own cursor position, activating another window and leaving text inputs unfocused.

 ## Accessibility and input
 
@@ -189,12 +221,38 @@ The AX provider supports:
 - active element, focus, hit testing, clear, and accessibility activation;
 - primary and secondary application windows.
 
+AppKit omits `AXEnabled` from elements that have no disabled state, and React
+Native macOS Paper views publish it only when `accessibilityState.disabled` is
+set. The provider therefore reports `enabled: true` when an element's attribute
+list does not contain `AXEnabled`, matching how assistive technologies treat
+it. An element that lists `AXEnabled` without a readable value still reports
+an unsupported enabled state. Fabric views always publish the attribute.
+
 Quartz Event Services supplies physical pointer, keyboard, text, and wheel
 input. Physical input requires Accessibility/PostEvent authority for the
 responsible process and an unlocked interactive Aqua session. Missing authority
 returns `input-unavailable`; the provider never substitutes unrelated
 accessibility activation and reports physical success.
 
+A locked screen or a login session that is not the active console prevents
+applications from publishing complete accessibility windows and from receiving
+physical input. Launch, attach, window discovery, and new pointer, keyboard,
+text, or wheel input check the login session and fail immediately with
+`input-unavailable` and a `session` diagnostic instead of retrying into a
+window-enumeration error. Key and button releases remain allowed so recovery
+can complete while the session is locked.
+
+Activation sets the application's `AXFrontmost` attribute, which a trusted
+client applies immediately, and falls back to `NSRunningApplication.activate`
+only if that fails. Cooperative workspace activation was observed to wait about
+a second for the active application to yield. Activation completes when the
+application reports `AXFrontmost` and the primary window reports `AXMain`;
+a timeout names the application that kept keyboard focus.
+
+A physical click first hit-tests its target. When another element owns the
+point, `element click intercepted` names the occluding element, or the external
+application and process that own it.

 Windows and Win32 share implementation but retain distinct endpoint and
 renderer capabilities. Minimized-window capture remains unsupported rather
 than changing app state through an implicit restore.

+## Modern component previews
+
+```tsx
+import { Callout, FocusZone, useNativeViewTarget } from '@fluentui-react-native/native-core/macos';
+// Windows uses the equivalent /windows entrypoint.
+```
+
+These previews require React 19 and the current native-core registration.
+`useNativeViewTarget` supplies a passive live callback binding; attach its
+`ref` to a materialized native View. Rect/point anchors use local logical
+coordinates relative to such a live owner, not global screen coordinates.
+
+Callout's ref is an opaque-presentation command handle; `content.ref` is the
+actual View ref. Controlled `open` is requested presence, and physical native
+closure latches the generation until false-to-true or a changed
+`presentationKey`. `onReady` is separate from legacy `onShow`. FocusZone
+preserves its actual native root `ref` and publishes confirmed requests through
+`commandsRef`. Neither ref assignment nor a void native focus return is
+confirmation. Requests support abort and timeout, and reject stale lifetimes.
+
+Modern and legacy facades share the native registrations; Callout's facades
+also share a hook-free private host that applies native-safe positioning and
+appearance values. Both modern facades are phased components: the first phase
+owns hooks and the presentation/command lifetime, and the hook-free render
+phase merges render-time pass-through props. When a modern facade is used as
+a slot, supply its first-phase props (listed in each `SPEC.md`) through the
+slot props. macOS shares Swift focus eligibility/actual-responder and
+placement behavior between the renderer adapters; the existing navigation
+algorithm is not rewritten merely to change language.
+
+Windows source/codegen and the native library build are qualified on RNW 0.81.35.
+Modern FocusZone command/target-lifetime, legacy navigation, legacy and
+modern Callout readiness, explicit operations, outside-input and Escape
+dismissal, rearm, owner focus return, flat Menu composition, and 100% scale
+anchor geometry pass on Windows. Win32 legacy FocusZone and legacy Callout
+outside-click/recreate and Escape cases pass. Remaining Windows protocol
+races are tracked in [#4374](https://github.com/microsoft/fluentui-react-native/issues/4374);
+the DPI/RTL/scroll geometry, repeated-cycle resource, and assistive-technology
+matrix is tracked in [#4375](https://github.com/microsoft/fluentui-react-native/issues/4375).
+macOS Fabric and Paper pass the updated authored Callout and Menu composition
+cases; this does not qualify the remaining geometry and accessibility matrix.

+Root/Win32 admission, older-peer builds, popup-family transactions,
+restoration/Tab policy, text fragments, modal containment, and a real module
+remain explicit gates. Remaining work is tracked under the

+# Modern Callout
+
+Owner-authorized initial contract, 2026-10-02. `/macos` and `/windows` preview
+only; not all-host root admission. See the
+[package qualification gates](../../../README.md#modern-component-previews)
+for remaining geometry, lifecycle/accessibility, Menu/Popover, Win32, and
+peer-floor work and the owning workstream issues.
+
+Callout is unstyled. Its React 19 ref is a presentation handle, deliberately
+not the hidden native marker. `content` forwards appearance, accessibility,
+events and an actual View ref to one materialized attachment host; arbitrary
+host replacement/collapse is not allowed.
+
+Callout is a phased component. `ref`, `open`, `presentationKey`, and `anchor`
+drive hooks in its first phase; when Callout is used as a slot, supply them
+through the slot props, because render-time values for them are ignored.
+Render-time `placement`, `onReady`, `onDismissed`, and children are merged, and
+render-time `content` props compose with the slot's content props and refs.
+
+`open` is externally requested presence. Native closure reports onDismissed
+and latches that generation closed. Retaining open=true does not reopen.
+False->true or a changed presentationKey rearms. onReady means attached content
+and valid positioning, not child-focus confirmation. A missing live anchor
+does not present at the origin.
+
+View anchors track committed attachment; rect/point anchors are snapshots in
+local logical units relative to their live owner. No public numeric tags,
+global screen coordinate guesses, or inline Text/shadow-tree geometry.
+Placement resolves logical start/end, alignment, gap, flip and work-area shift.
+
+Handle operations require the current opaque presentation. Native events,
+not void command returns, confirm focus/close/reposition. Abort, target changes,
+unmount, invalid generation and timeout produce explicit outcomes. Timeout is
+unconfirmed; cancellation cannot undo an already-executed native mutation.
+Focus remains scoped to eligible content and active owned windows.
+
+Pointer input outside the popup family, Escape in focused content, and losing
+the host report `native-light-dismiss` or `host-detached`. Input in a nested
+popup does not dismiss the popups that own it. Closing a presentation that
+holds keyboard focus returns input to the owner window's retained focused
+component; outside input that already moved focus is not overridden. Whether
+a pointer-opened trigger is that component follows its pointer-focus mode:
+Windows and Win32 focus a pressed trigger by default, macOS follows AppKit and
+keeps the previous first responder, and `pointerFocus: 'always'` focuses the
+trigger on every platform. On
+Windows, outside input is observed for the owner island and other application
+windows; application deactivation dismisses only presentations that hold
+focus. A Menu still restores its trigger explicitly after an item closes it.
+
+Request-only veto, precise light-dismiss classification, policy-driven
+restoration, popup-family transactions, modal containment and text fragments
+are deferred; no success-shaped substitutes are provided.

+# Modern FocusZone
+
+Owner-authorized initial contract, 2026-10-02. Native-core `/macos` and
+`/windows` preview only; remaining runtime qualification is tracked in
+[#4374](https://github.com/microsoft/fluentui-react-native/issues/4374), and
+old peer floors and all-host admission in
+[#4376](https://github.com/microsoft/fluentui-react-native/issues/4376).
+This is not root/Win32 admission.
+
+The component is unstyled and preserves the actual native-zone instance in
+the React 19 `ref` prop. `commandsRef` publishes a separate mounted command
+surface; it is null after unmount. Both native and caller refs compose through
+framework-base slots, including callback cleanup.
+
+FocusZone is a phased component. `commandsRef` and `defaultTarget` drive hooks
+in its first phase; when FocusZone is used as a slot, supply them through the
+slot props, because render-time values for them are ignored. Render-time
+navigation, `disabled`, and view props are merged, and a render-time `ref`
+composes with the slot's `ref`.
+
+Direction, spatial opt-in, arrow wrap, Tab mode, disabled, and a live
+defaultTarget translate to the existing per-host navigation engine.
+Navigation remains platform-native by default; it is not modal containment.
+A disabled zone reports `not-focusable` through the native command result.
+
+`requestFocus` supports default/first/last or a live scoped descendant.
+Confirmation comes from native responder/focused-component identity, not a
+void focus return. Entry preferences must not override an explicit command
+destination. Requests are generation-fenced, cancellable, bounded by
+an explicit timeout, and invalidated on component/target replacement.
+Missing mounts are not queued; inactive windows are not reactivated.
+A zone inside an owned popup, such as Callout content, is active while the
+popup's owner chain includes the active window, so a Menu can enter and move
+within its list on both hosts.
+Cancellation cannot reverse a mutation already executed natively.
+
+Disabled discoverability, remembered focus, natural cross-popup Tab
+continuation, and all-host root behavior are separate admission gates.
