Windows parity: Standard-control UIA, sidebar selection and Narrator qualification remain #745

Current reconciliation - 2026-11-09

The 2026-10-13 narrowed scope below supersedes the original terminal-text/edge-element/live-announcement demands: macOS exposes none of those as required parity surfaces. The remaining contract is named roles/actions for macOS-presented dialogs, sheets, alerts, menus and standard controls, correct sidebar selection, daemon-driven tree updates, and live UIA/Narrator qualification.

Merged PR #911 migrates forms to the shared native sheet framework; PR #965 adds the native New Workspace form/Create & Open path. PR #963 supplies bounded selected-pane focus/input qualification, not general accessibility conformance. Still open / Partial: the complete standard-control matrix, Graph/Quick Chats native selection #801, daemon-to-tree integration and Narrator behavior. Existing default integration includes button/command fallbacks; it is not complete physical-pointer fidelity or direct proof of the application's separate pipe handle.

The original report, acceptance criteria and historical evidence below are preserved; the dated scope/progress above supersedes obsolete missing-feature claims.

Is your feature request related to a problem?
Parity row UI Automation tree (Accessibility, input, and visual behavior) in investigation/ui-parity-matrix.md is Partial.

macOS: Names, roles, selection, invoke/toggle, focus and live status for every visible surface.

Windows today: A broad UIA tree with named fragments across the shell.

Gap: Native terminal text results, applied selection, visible caret/geometry, range/HRESULT conformance, retained-generation behaviour, atomicity, daemon-to-model UIA integration and some dialogs need implementation or evidence.

Describe the solution you'd like
Implement the terminal TextPattern and selection exposure and the remaining dialogs, then a UIA conformance pass.

Describe alternatives you've considered
N/A

Additional context
This is an implementation gap: work remains in the product before the row can be validated. Parity status and the beta25 Dev Box review are recorded in #719.
