+# PR_11_308 Report - Workspace V2 Palette Producer Removal and Import UX Cleanup
+
+## Purpose
+Remove palette-manager from Workspace V2 Producer selection, remove duplicate textarea import path, and keep a single Import Workspace Session JSON flow with file-picker-first behavior.
+
+## Files Changed
+- `tools/workspace-v2/index.js`
+- `docs/dev/reports/PR_11_308_report.md`
+
+## Implementation Summary
+- Removed runtime creation/wiring of `Import Textarea JSON` button path.
+- Kept `Import Workspace Session JSON` as the primary import trigger:
+  - opens hidden file picker
+  - selected file content populates textarea
+  - import validates/loads automatically
+- Added manual textarea fallback only when file picker is unavailable and textarea has JSON.
+- Removed `palette-manager-v2` option from the Producer tool dropdown at runtime.
+- Updated Producer default selection to a non-palette tool (`asset-browser-v2`) with first-option fallback.
+
+## Validation Commands
+- `node --check tools/workspace-v2/index.js`
+
+## Validation Results
+- PASS: JavaScript syntax check succeeded for `tools/workspace-v2/index.js`.
+
+## Full Samples Smoke Test
+- Skipped.
+- Reason: change is scoped to Workspace V2 `index.js` producer/import wiring and does not modify shared sample loader/framework.
