# PR_11_275 Workspace V2 Current Session JSON Export Fix Report
2+
3+
## Scope
4+
Workspace V2 export controls only.
5+
6+
## Files Changed
7+
- tools/workspace-v2/index.js
8+
- tests/runtime/V2CurrentSessionExport.test.mjs
9+
- docs/pr/PLAN_PR_11_275_WORKSPACE_V2_CURRENT_SESSION_EXPORT_FIX.md
10+
- docs/pr/BUILD_PR_11_275_WORKSPACE_V2_CURRENT_SESSION_EXPORT_FIX.md
11+
- docs/dev/reports/PR_11_275_workspace_v2_current_session_export_fix_report.md
12+
13+
## Implementation Summary
14+
- Fixed `exportCurrentSessionJson()` to perform real file download instead of only mirroring JSON into textarea.
15+
- Export now resolves payload from active-session source path (`readActiveSessionPayloadForLibraryActions`) for alignment with Save Session active-session gating.
16+
- Added explicit no-active-session block message:
17+
- `No active Workspace V2 session is available to export.`
18+
- Added success status message:
19+
- `Exported current workspace session JSON.`
20+
- Download filename now includes tool/session identity when available:
21+
- `<toolId>-<hostContextId>.json` (or fallback session token for missing hostContextId)
22+
- Export preserves payload exactly (serialized active payload only).
23+
24+
## Validation Commands
25+
1. `node --check tools/workspace-v2/index.js`
26+
- PASS
27+
2. `node --check tests/runtime/V2CurrentSessionExport.test.mjs`
28+
- PASS
29+
3. `node tests/runtime/V2CurrentSessionExport.test.mjs`
30+
- PASS
31+
- Results: `tmp/v2-current-session-export-results.json`
32+
33+
## Additional Non-Blocking Note
34+
- Ran `node tests/runtime/V2ImportExport.test.mjs` once as an extra regression check.
35+
- Result: FAIL due to existing brittle token assertion unrelated to this export fix scope.
36+
- Not included in required targeted PR_11_275 validation set.
37+
38+
## Full Samples Smoke Decision
39+
- Skipped full samples smoke test.
40+
- Reason: scope is Workspace V2 export control behavior only and covered by targeted runtime test.

# BUILD_PR_11_275_WORKSPACE_V2_CURRENT_SESSION_EXPORT_FIX
2+
3+
## Purpose
4+
Implement Workspace V2 current-session JSON export download behavior with explicit actionable status text.
5+
6+
## Files
7+
- tools/workspace-v2/index.js
8+
- tests/runtime/V2CurrentSessionExport.test.mjs
9+
- docs/dev/reports/PR_11_275_workspace_v2_current_session_export_fix_report.md
10+
11+
## Implementation
12+
1. Update `exportCurrentSessionJson()` to resolve export payload from active session source via `readActiveSessionPayloadForLibraryActions()`.
13+
2. If no active valid session exists, show:
14+
- `No active Workspace V2 session is available to export.`
15+
3. If active session exists:
16+
- Serialize exact active payload JSON
17+
- Create Blob and object URL
18+
- Trigger browser download via temporary anchor
19+
- Filename includes tool/session identity when available
20+
- Show status: `Exported current workspace session JSON.`
21+
4. Preserve payload unchanged; no fallback/default data path.
22+
5. Add targeted runtime test verifying:
23+
- active export status and filename identity
24+
- no-active export status
25+
- payload preservation and required code tokens
26+
27+
## Acceptance
28+
- Export button triggers JSON download for active session.
29+
- No-active export path is explicit and actionable.
30+
- Export source aligns with active-session source path used by Save flow checks.
31+
- No session behavior changes outside export controls.
32+
33+
## Validation
34+
- node --check tools/workspace-v2/index.js
35+
- node --check tests/runtime/V2CurrentSessionExport.test.mjs
36+
- node tests/runtime/V2CurrentSessionExport.test.mjs

# PLAN_PR_11_275_WORKSPACE_V2_CURRENT_SESSION_EXPORT_FIX
2+
3+
## Purpose
4+
Fix Workspace V2 "Export Current Session JSON" so it downloads the active session payload with explicit success/failure status messaging.
5+
6+
## Scope
7+
- tools/workspace-v2/index.js
8+
- tests/runtime/V2CurrentSessionExport.test.mjs
9+
- docs/report only
10+
11+
## Goals
12+
- Export downloads JSON file when a valid active session exists.
13+
- Export uses same active session source path used by Save Session active-session checks.
14+
- Export filename includes tool/session identity when available.
15+
- Export preserves active payload exactly.
16+
- Export shows explicit no-active-session status when unavailable.
17+
- No fallback/default export payloads.
18+
19+
## Out of Scope
20+
- No session library/diff/merge behavior changes.
21+
- No schema changes.
22+
- No shared framework/sample changes.
23+
24+
## Validation
25+
- node --check tools/workspace-v2/index.js
26+
- node --check tests/runtime/V2CurrentSessionExport.test.mjs
27+
- node tests/runtime/V2CurrentSessionExport.test.mjs
