Shared editable revision combo

Pinned source: 7338078f8ddd924b8cddee35f512f2286072136d, CChooseVersion in ChooseVersion.h, HistoryCombo.cpp/.h, and the IDC_COMBOBOXEX_VERSION controls in the Switch/Merge/Branch/Tag/Reset/New Worktree/Export resources.

The commit-revision row previously used a plain NSTextField. It now uses one editable NSComboBox implementation in Switch, Merge, Branch/Tag, New Worktree and Reset and Export, retaining each caller's own focus/enablement/selection ownership. The separate Reset text-field adapter has been removed. Branch/tag popups retain their existing full-reference behavior.

CChooseVersion::SelectRef adds an otherwise-unclassified revision to its version combo. The native models now retain those programmatic custom selections during the dialog session and show them in the combo. Initial custom presets enter the same list. CR/LF folding, surrounding whitespace trimming and the bounded append behavior follow HistoryCombo. Ordinary typing does not normalize text or add an entry; Log's selected hash changes the text without inserting a history item, matching the source's SetWindowText call. No new persistent history store is used: ChooseVersion does not load a version history, and Switch's SaveHistory call is commented out.

Native choices retain exact UTF-8 identity, including case and Unicode variants, so distinct Git tokens are not collapsed. This deliberately differs from the source HistoryCombo's default case-insensitive duplicate search. Native values also retain qualified custom refs, consistent with the existing native picker routing, instead of stripping the source's refs/ prefix. Full Windows locale, whitespace and overflow behavior remains unverified.

The combo disables automatic completion, preserves text/caret when its item list changes, and binds both typing and native popup selection to the captured model. Disabled and dismantled controls reject callbacks. Scheduled focus requires a live enabled control/coordinator and then uses each owner's existing focus guard. Checkbox options, repository operations, progress and modal picker ownership are unchanged by this control replacement.

The existing Switch and creation picker receivers now join the common app-object cache and default CI group; their standalone scripts delegate to it. The grouped check also retains Merge picker coverage. This does not certify physical popup mouse/Return/Escape/VoiceOver behavior, every layout/theme/minimum size, signed sandbox execution or complete ChooseVersion/dialog parity.

Eight grouped native cases passed with both Git engines, followed by two affected control cases after adding Export. The final Debug build passed; Core was unchanged and not retested. See the scoped acceptance.

The connected Log reference-navigation family adds source reference-set scopes, multi-tip/range picking, bounded exact recents and owned browser/preparation lifetime. ChooseVersion histories remain session-only.

The shared dropdown popup now rejects disabled/dismantled callbacks and deferred focus on retired controls. Rebase uses it with original reference icons; see Rebase reference preparation.

Shared ChooseVersion handoffs — October 15, 2026

Pinned ChooseVersion.h::OnBnClickedChooseVersion starts a single-selection Log at the entered revision and excludes the working-tree row. Its BrowseRefs route refreshes the catalog even on Cancel, preserving canonical branch/tag/custom reference identity. The shared native coordinator now supplies the revision before constructing Log, with private preferences and the owner's appearance and opacity. Switch, Create Branch/Tag and New Worktree now configure the same shared production Log commands as Merge and Reset. Accepted hashes enter the editable session choices; source ChooseVersion does not load/save a persistent version history here, so native choices remain session-scoped.

One request owns its pending return until both child retirement and actual sheet detachment. Duplicate, refused, obsolete and retired callbacks cannot replace a newer request. A byte-exact snapshot of target and revision inputs rejects results that would overwrite an edited draft. Branch/Tag additionally retains its HEAD, name and follow-up options; New Worktree retains its HEAD, destination and branch options. Catalog results also validate their initiating selection draft after Git returns. Cancel still refreshes catalogs for an unchanged draft.

Export participates in the same chooser handoff, retaining its target, destination and whole-project selection; accepted commits also enter its session choices. Merge/Export catalog reads and Create Branch/Tag metadata now keep global Quit/access ownership until settlement after forced owner close, matching the existing shared Switch reader. This is a workflow handoff improvement; it does not prove all options, complete visual parity or signed sandbox acceptance. The dated QA record states the actual grouped native scope and any observed failures.

Shared chooser QA records the actual source comparison, six accepted case/Git pairs, original failures/repairs and owned-process cleanup. Full dialog/application parity remains incomplete.
