+# PR_11_304 Report - Workspace V2 Clean Export/Import Implementation
+
+## Purpose
+Replace Workspace V2 import/export with a clean, manifest-only implementation in `tools/workspace-v2/index.js`.
+
+## Scope
+- `tools/workspace-v2/index.js` only
+- No schema changes
+
+## Files Changed
+- `tools/workspace-v2/index.js`
+
+## Implementation Summary
+1. Added Import/Export section-local status wiring
+- Added `initializeImportExportSectionStatusNode()`.
+- Added `setImportExportStatus(message)`.
+- Import/Export actions now always write visible status in the Import/Export section.
+
+2. Export implementation cleanup
+- `exportWorkspaceSessionJson()` now uses one direct path:
+  - `Export clicked`
+  - build full workspace manifest JSON
+  - validate manifest
+  - write JSON to textarea
+  - download via Blob + temporary anchor click
+  - `Export success` or `Export error: ...`
+- Removed legacy wrapper dependence (`workspaceSession`, `games`) from export structure.
+
+3. Manifest export shape updated
+- `buildWorkspaceSchemaDocument()` now produces:
+  - `documentKind`
+  - `schema`
+  - `version`
+  - `id`
+  - `name`
+  - `tools.workspace-v2`
+- `tools.workspace-v2` includes:
+  - `schema`
+  - `game`
+  - `defaultToolId`
+  - `activeToolId`
+  - `activeHostContextId`
+  - `activeSession`
+  - `savedSessions`
+- `activeSession` and `savedSessions` preserve real payload objects without rewriting.
+
+4. Import implementation cleanup
+- `importWorkspaceSessionJson()` now uses one direct path:
+  - `Import clicked`
+  - parse textarea JSON
+  - reject raw tool payload JSON with exact message:
+    - `Workspace import requires a workspace manifest JSON`
+  - validate manifest structure
+  - load `activeSession` into `sessionStorage`
+  - load `savedSessions` into `localStorage`
+  - set current active session/tool
+  - keep textarea as manifest JSON
+  - `Import success` or `Import error: ...`
+
+5. Validation function alignment
+- Reworked `validateWorkspaceSchemaDocument()` to validate manifest-only structure with `tools.workspace-v2`.
+- Added `validateWorkspaceToolSessionPayload()` for active/saved tool session payload validation.
+
+## Validation Commands Run
+1. `node --check tools/workspace-v2/index.js`
+2. `@' ... legacy wrapper removal checks ... '@ | node`
+3. `rg -n "initializeImportExportSectionStatusNode\(|setImportExportStatus\(|Workspace import requires a workspace manifest JSON|Export clicked|Export success|Import clicked|Import success" tools/workspace-v2/index.js`
+4. `Select-String -Path tools/workspace-v2/index.js -Pattern 'documentKind: "workspace-manifest"','schema: "html-js-gaming.project"','"workspace-v2": \{','activeSession: this.cloneSessionValue\(activePayload\)','savedSessions: this.cloneSessionValue\(library\)'`
+
+## Validation Results
+- Command 1: PASS
+- Command 2: PASS (`legacy wrapper removal checks: ok`)
+- Command 3: PASS (required status and import-rejection tokens found)
+- Command 4: PASS (required manifest export shape tokens found)
+
+## Requirement Mapping
+- Clean full workspace manifest export: PASS
+- `tools.workspace-v2` required fields present: PASS
+- Active payload preserved (no payload rewrite): PASS
+- Blob + anchor download path: PASS
+- Import parses and validates manifest: PASS
+- Tool payload import rejection message: PASS
+- Section-local status messages (`Export clicked/success/error`, `Import clicked/success/error`): PASS
+- No hard-override/multi-handler import-export junk paths introduced: PASS
+
+## Full Samples Smoke Decision
+- Skipped full samples smoke test.
+- Reason: change is limited to Workspace V2 import/export logic in one file and validated via targeted checks.
