Native patch file panel

Source pin: 7338078f8ddd924b8cddee35f512f2286072136d, TortoiseMerge/FilePatchesDlg.cpp Init, OnLvnItemchangedFilelist, OnNMDblclkFilelist, OnNMRclickFilelist, PatchAll and PatchSelected; MainFrm.cpp OnUpdateViewShowfilelist/OnViewShowfilelist.

Review/apply single patch now uses an AppKit table for Files to patch. Its unsorted Path/State columns retain patch order, multiple selection, native file icons, basename labels, complete target-path tooltips, bold current preview, muted patched rows and red error rows/diagnostics. The existing per-file Git application, independent checked backend API and immutable source patch remain.

Highlighting changes only the selection, matching LVN_ITEMCHANGED; it does not replace a comparison or change checkboxes. Double-click, Return/keypad Enter or Preview patched file load exactly one selected eligible file. Error-row Preview shows its existing diagnostic inline. Completed rows cannot be previewed again. This supersedes the earlier single-highlight automatically opening a comparison.

Native right-click selection preserves an existing multi-selection. Context commands retain source order: Preview patched file, Patch all files, Patch selected files. They reuse the original comparison/patch icons and application context-icon preference. Shift-F10 opens that native menu at the selected row; ordinary AppKit arrow/Shift/Command selection and type selection remain native behaviors. Captured menus bind both their selection and loaded generation. Validation and dispatch recheck operation/draft/refresh/retirement gates. Dismantling a hidden table retires its coordinator so an old retained menu cannot apply files.

View → Patch file list and the window's Hide/Show file list button toggle the panel. This is a per-window view choice, as the source command is; no global preference is introduced. Hiding a focused list transfers focus to the comparison and keeps highlighted IDs. The menu remains available to restore the panel.

Review contributes scoped native Open/Reload/Save, applicable Find/patch commands, View file-list state, Settings and Help through the shared Merge menu owner. It inherits reconstruction/tracking, key-window epochs and detached/retired refusal. Unsupported comparison commands and regex submenus are not added. Embedded comparison controls keep their existing separate presentation and ownership.

The batch evidence records eight passing native case/engine runs across seven distinct pairs. This includes both Git versions for the panel, per-file application and full import/editor/lifecycle/output ownership, plus the scoped comparison/merge menus. A retained Import fixture now waits for the actual Go to Line gate before its unchanged enabled/range/byte assertions. A wrong Help topic and the readiness helper's protocol constraint were corrected during compilation. All owned receivers were reaped and independently absent. No Core behavior changed or Core suite reran. Remaining work includes initial failed-hunk/conflict counts, source hunk/conflict application behavior, complete editor/ribbon commands, physical keyboard/context-popup/accessibility and width/geometry acceptance, large-patch performance and signed installed Finder/sandbox/App Store execution. This is partial source parity, not certification of the full patch family.

Actual AppKit result-list captures are published in light appearance and dark appearance. They show two patched rows, a failed row and its diagnostic alongside the original patch. Comparison-view candidates also confirmed the initial viewport and file icons; they are retained in local QA. These captures do not prove keyboard popup or full dialog parity.

The recorded-base recovery continuation adds initial Ready/Conflict/Error classification, versioned-base retry, an embedded native three-pane preview and clean-merge Patch all/selected continuation. Earlier text listing all initial-state and conflict preview behavior as absent is historical; the continuation records the implemented paths and remaining special-file scope.
