 - Result:
   - PASS
 
+## Execution Notes
+- No schema changes were made.
+- Workspace V2 baseline palette initialization and reset/export guard flow are contained in `tools/workspace-v2/index.js`.
+- Export baseline remains a single active palette source under `tools.palette-browser` with empty `swatches` allowed.
+
 ## Expected Runtime Outcome
 - Fresh page load and full reset now keep exactly one active palette baseline available.
 - Export no longer fails solely because active palette state was missing after refresh/reset.

+
+## Implementation
+- Maintain one baseline active palette source in Workspace V2 state.
+- Ensure baseline creation is called on startup and full reset.
+- Ensure export materializes `tools.palette-browser` from that source with schema-valid shape.
+
+## Baseline Rule
+When missing, initialize a single active palette baseline equivalent to:
+- `tools.palette-browser.swatches = []`
+(with no extra palette entries and no legacy locations)
+
+## Validation
+- `node --check tools/workspace-v2/index.js`
+
+## Non-Goals
+- No schema file edits
+- No palette manager session reintroduction
+- No legacy `workspaceSession` / `games[]` shapes

+# PLAN_PR_11_309
+
+## Purpose
+Guarantee Workspace V2 manifest always has a single valid `tools.palette-browser` baseline during initialization and full reset.
+
+## Scope
+- `tools/workspace-v2/index.js`
+- Workspace V2 initialization/full reset/export baseline only
+- No schema changes
+
+## Steps
+1. Verify Workspace V2 initialization creates baseline active palette state when missing.
+2. Verify full reset recreates baseline active palette state when missing.
+3. Verify export path reads palette from the baseline source and emits `tools.palette-browser` safely.
+4. Run targeted syntax validation.
+5. Produce report and PR zip artifacts.
