Rebase action controls
This connected native control family follows IDD_REBASE,
RebaseDlg.cpp::OnBnClickedSplitAllOptions, SetAllRebaseAction,
AddBranchToolTips, SetControlEnable, GitLogListAction.cpp's selected and
unselected action setters, and Utils/MiscUI/MenuButton.cpp at pinned commit

Bulk actions
The action row now has one native split control, replacing the separate Pick ALL and Options buttons. Its source-ordered menu contains Pick ALL, Squash ALL, Edit ALL, Skip unselected, Squash unselected and Edit unselected. Choosing an item executes it and remembers its label for the main segment's next click. This is window-local state, not a new preference. Menus retain the original action icons.
Squash ALL and Squash unselected leave the oldest replay occurrence unchanged. In ordinary Rebase they also leave non-single-parent commits unchanged. The selected-row Squash command likewise skips the oldest occurrence and ordinary merge commits. Cherry Pick retains its different merge rules. A skipped oldest commit can still leave an invalid first retained Squash; the existing Start validation continues to reject that plan.
Unselected actions preserve the highlighted occurrences. The menu captures the plan/control generation, occurrence order/actions, selection and branch/upstream/onto options, and can apply once. A replaced plan, changed selection, modal child, loading operation, busy or retired owner refuses a late callback. Selection or option changes invalidate the generation even if their old values are restored. The main segment repeats the current command against the current editable plan.
Reference information and footer
Branch and Upstream now expose full revision, author/email, long date and commit message tooltips. Metadata is read using the already captured canonical plan hashes, so a same-named tag does not redirect a branch tooltip. The reads share the plan's cancellation and access/Quit lifetime and publish only with the current plan. Tooltip length follows the source's 8,000 UTF-16-unit bound without splitting a surrogate pair. A metadata failure leaves its diagnostic in the tooltip rather than changing the plan's target. Incomplete/replaced references show the entered reference until their current metadata is ready.
The Edit/Split commit checkbox now sits beside Continue in the footer at an eligible Edit/Squash pause. Existing split recovery and native Commit selection remain in use. Force, Preserve merges and Abort expose explanatory help.
Successful Rebase completion uses the same native split control. Its command sets remain direct Show log/Restart rebase or after-Fetch Show log/Push/Send Mail/ Rebase. A menu choice becomes the remembered primary action; successful new completion resets it to Show log. Captured completion callbacks are one-use and refuse replaced phases/targets. Existing repository/access and mail handoffs remain unchanged. Cherry Pick and Rebase launched from Log retain the source's absence of these post buttons.
Native captures
The native split control keeps the chosen bulk action in its main segment. Squash ALL leaves an existing Edit action on the oldest occurrence unchanged.

At an actual Edit pause, Edit/Split commit appears beside the continuation button.

Evidence and remaining acceptance
See dated build/native evidence. The connected receiver uses actual native segmented controls and menus and real Edit/Abort/Squash replay. Structural row-action/drag recovery and reference picker/cancellation receivers are retained in the same grouped checkpoint.
Full physical menu/key/VoiceOver interaction, all minimum-size combinations, selected-row contrast, signed sandbox/Finder and complete Rebase parity remain open. The Preserve merges help describes the native structural engine rather than repeating the Windows engine's obsolete reordering limitation verbatim.
The revision menu family adds source-ordered row-action visibility, merge-parent and unified mode menus, exact captured menu receipts and native keyboard/AX entry. The connected durable pending action family now handles paused reproducible native sessions; older/custom structural conversion remains explicit.
