+# PR_26124_060-palette-manager-undo-redo-and-multi-tag-select Report
+
+## Summary
+Palette Manager V2 now supports local undo/redo for user palette mutations, checkbox multi-select on User Palette swatches, and batch tag application from the Tags accordion.
+
+## Existing History Search
+- Searched under `src/` for undo/history/command stack classes.
+- No suitable reusable undo/history/command stack class was found for Palette Manager V2 user palette mutations.
+- Implemented the smallest local history stack in `tools/palette-manager-v2/modules/PaletteHistoryStack.js`.
+
+## Files Changed

+
+## Validation
+- JavaScript syntax checks: PASS.
+- Targeted served-browser Palette Manager V2 undo/redo, multi-select, batch tag, and source pin validation: PASS.
+- `git diff --check`: PASS with Git LF-to-CRLF warnings for changed Palette Manager files.
+- `npm run test:workspace-v2`: FAIL because the script is missing from `package.json`.
+- Full samples smoke test: skipped by instruction.
+
+## Targeted Browser Coverage
+- Undo and Redo start disabled.
+- Adding a user swatch enables Undo.
+- Undo removes the added swatch and enables Redo.
+- Redo restores the swatch and selected swatch display.
+- User Palette checkbox click does not select the tile.
+- Selected-count status updates when User Palette checkboxes are checked.
+- Add Tag applies a lowercase tag to all checked User Palette swatches.
+- Existing tag click removes the tag from all checked User Palette swatches when all checked swatches have it.
+- Undo/redo restores batch tag mutations.
+- Source swatch pin adds a user swatch.
+- Undo/redo restores source pin mutations.
+
+## Manual Test
+1. Open Palette Manager V2 through a local server.
+2. Add a user swatch, click `Undo`, and confirm it is removed.
+3. Click `Redo` and confirm the swatch returns with selected details restored.
+4. Add a second user swatch.
+5. Check both User Palette tile checkboxes and confirm the selected count is `2 selected`.
+6. Type a mixed-case tag in the Tags accordion and click `Add`.
+7. Confirm the lowercase tag appears on both checked swatches.
+8. Click the tag in the Tags accordion and confirm it toggles across the checked swatches.
+9. Pin a source swatch and confirm Undo/Redo restores the pin state.
