# PR_11_267 Workspace V2 Default Tool + Producer Initialization Fix Report
2+
3+
## Scope
4+
Workspace V2 only.
5+
6+
## Files Changed
7+
- tools/workspace-v2/index.html
8+
- tools/workspace-v2/index.js
9+
- tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs

13+
14+
## Implementation Summary
15+
- Default tool fix:
16+
- Set `Palette Manager V2` as explicitly selected option in Workspace V2 tool selector.
17+
- Added JS load-time enforcement with explicit default tool ID (`palette-manager-v2`) so behavior does not depend on option ordering.
18+
- Producer initialization fix:
19+
- Added load-time initialization that creates a real active Workspace V2 session when none exists.
20+
- Initialization now:
21+
- builds a versioned payload with selected tool ID
22+
- validates payload size
23+
- creates hostContextId
24+
- writes payload to sessionStorage
25+
- sets active current payload/source
26+
- Added clear initialization status message confirming session is active for Save.
27+
- Save behavior result:
28+
- New Session ID can be saved immediately after load (no "No active Workspace V2 session is available to save" at first save attempt).
29+
30+
## State Model Alignment
31+
- Initialization runs before normal render/update passes and uses existing session fields (`currentHostContextId`, `currentSessionPayload`) that feed the current computed UI model pipeline.
32+
- No duplicate state flags added.
33+
- No fallback/demo data added.
34+
35+
## Validation Commands
36+
1. `node --check tools/workspace-v2/index.js`
37+
- PASS
38+
2. `node --check tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs`
39+
- PASS
40+
3. `node --check tests/runtime/V2SessionLibraryActions.test.mjs`
41+
- PASS
42+
4. `node tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs`
43+
- PASS
44+
- Results: `tmp/v2-workspace-default-tool-init-results.json`
45+
5. `node tests/runtime/V2SessionLibraryActions.test.mjs`
46+
- PASS
47+
- Results: `tmp/v2-session-library-actions-results.json`
48+
49+
## Full Samples Smoke Decision
50+
- Skipped full samples smoke test.
51+
- Reason: change is Workspace V2-only initialization/default-selection behavior with targeted runtime coverage.

# BUILD_PR_11_267_WORKSPACE_V2_DEFAULT_TOOL_PRODUCER_INIT_FIX
2+
3+
## Purpose
4+
Enforce Palette Manager as default Workspace V2 tool and initialize producer session state during load.
5+
6+
## Files
7+
- tools/workspace-v2/index.html
8+
- tools/workspace-v2/index.js
9+
- tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs
10+
- docs/dev/reports/PR_11_267_workspace_default_tool_producer_init_fix_report.md
11+
12+
## Implementation
13+
1. Set Palette Manager option as explicitly selected in Workspace V2 tool selector.
14+
2. Add load-time default tool selection enforcement in JS (non-order-dependent).
15+
3. Add load-time producer session initialization that:
16+
- creates versioned payload for selected tool
17+
- creates hostContextId
18+
- writes session to sessionStorage
19+
- sets active session payload/source
20+
4. Ensure initialization does not recreate session when one already exists.
21+
5. Keep all session UI state updates in existing model refresh flow.
22+
23+
## Acceptance
24+
- Workspace V2 loads with Palette Manager as selected tool.
25+
- Active session exists immediately after load.
26+
- Save Session for a new ID succeeds without "no active session" error.
27+
- No schema/cross-tool side effects.
28+
29+
## Validation
30+
- node --check tools/workspace-v2/index.js
31+
- node --check tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs
32+
- node tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs
33+
- node tests/runtime/V2SessionLibraryActions.test.mjs

# PLAN_PR_11_267_WORKSPACE_V2_DEFAULT_TOOL_PRODUCER_INIT_FIX
2+
3+
## Purpose
4+
Fix Workspace V2 default tool selection and producer initialization so Save Session works immediately after load.
5+
6+
## Scope
7+
- tools/workspace-v2/index.html
8+
- tools/workspace-v2/index.js
9+
- tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs
10+
- docs/report only
11+
12+
## Goals
13+
- Set Palette Manager V2 as explicit default tool on load.
14+
- Initialize a real active Workspace V2 session on initial load.
15+
- Ensure Save Session can succeed for new IDs immediately after load.
16+
- Keep behavior aligned with PR_11_264/265 deterministic state model.
17+
18+
## Out of Scope
19+
- No schema changes
20+
- No cross-tool changes
21+
- No fallback/default demo data
22+
23+
## Validation
24+
- node --check tools/workspace-v2/index.js
25+
- node --check tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs
26+
- node tests/runtime/V2WorkspaceDefaultToolInitialization.test.mjs
