+# PR_26124_059-validation-viewer-clear-and-error-consolidation Report
+
+## Summary
+Palette Manager V2 Validation/Error Viewer now has a display-only Clear action, and duplicate user swatch validation messages are consolidated into a single line.
+

+- `docs/pr/PR_26124_059-validation-viewer-clear-and-error-consolidation/BUILD_PR.md`

+
+## Validation
+- JavaScript syntax checks: PASS.
+- Targeted served-browser Palette Manager V2 validation viewer and duplicate consolidation 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
+- Duplicate symbol/name/RGB-hex failures render as one consolidated line.
+- Name-only duplicate failures render as one line with only the failed field.
+- Clear empties the displayed viewer status and error list.
+- Clear does not remove or mutate User Palette data.
+- Repeating the same validation after Clear renders the message again.
+
+## Manual Test
+1. Open Palette Manager V2 through a local server.
+2. Add a user swatch.
+3. Attempt to add another swatch with duplicate symbol, name, and RGB/hex.
+4. Confirm the viewer shows one consolidated duplicate message.
+5. Click `Clear` and confirm the viewer output is empty.
+6. Repeat the duplicate action and confirm the message appears again.
