Commit native focus readiness — October 24, 2026

The hosted macOS 15.5/Swift 6.1.2 primary-dialog receiver failed its immediate author field-editor assertion after the author metadata read completed. Model readiness and SwiftUI's native field update are distinct events. The original fixture already waited for actual new-branch focus, but checked author/date focus synchronously.

The Commit controller now accepts branch, author, author-date and author-time focus commands against the current form receipt and original window. It attempts native focus immediately, then permits a bounded cancellable readiness retry for an attached, enabled control with the expected editability. Text fulfillment requires the actual field editor and selects the entire value. Date/time fulfillment requires the picker or its native descendant to own first responder. A newer request supersedes the previous request. Changed form/options, busy/Quit, modal sheets, retirement, another owner, or another responder revoke the request. The retry retains its controller/window weakly between attempts and ends after three seconds. It does not activate a window.

Pinned source: src/TortoiseProc/CommitDlg.cpp at 7338078f8ddd924b8cddee35f512f2286072136d, OnBnClickedCheckNewBranch (3026 onward) focuses and selects the new branch; OnBnClickedCommitSetauthor (3081 onward) preserves selection/copy while changing read-only state; OnBnClickedCommitSetDateTime and OnBnClickedCommitAsCommitDate (2986–3023) control date/time availability. The native Focus menu commands adapt these controls to macOS command routing.

The retained primary Commit options fixture now waits for actual author/date/time responders, tests a real attached field whose editability is not yet ready, and checks pending-request refusal across Quit, form-option changes and owner close. These are automated native-control assertions, not physical keyboard acceptance. The affected native Commit group passes with system and bundled Git. The shared final Debug build exits zero; five contradictory generic compiler exit-zero diagnostics are retained in the dated checkpoint. All 18 receivers attempted across the connected Sync/Stash/Commit checkpoint are independently confirmed absent. No new Core behavior or literal UI labels were introduced by the focus change. A full hosted rerun with the older SDK remains required; the original 95df5f46 macOS run failed, and a focused local pass does not replace it.
