- [samples2tools_batch_51_validation.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\samples2tools_batch_51_validation.txt)
- [samples2tools_batch_51_summary.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\samples2tools_batch_51_summary.txt)

Result:
- `PASS` across 15 checks, including:
  - Phase 20 fully removed
  - roundtrip sample/tool contract integrity
  - no active phase20 runtime hooks
  - games Workspace-only launch + strict host context + unified boot wiring

Commit comment:
`Add batch-51 final integrity sweep report (PASS): verify post-roadmap end-state across samples metadata contracts, phase-20 removal, workspace/tool runtime hooks, and workspace-only games launch/host context wiring.`

+Samples2Tools batch 51 summary
+Generated: 2026-04-24T22:59:15.948Z
+Purpose: provide a single end-state verification artifact after completing Samples2Tools roadmap implementation.
+
+Completed this batch:
+- Verified phase-20 hard removal from metadata and filesystem
+- Verified metadata-driven sample-to-tool roundtrip integrity and naming contracts
+- Verified no active Phase-20 runtime hooks remain in workspace/platform shell paths
+- Verified games lane Workspace-only launch + strict host context + unified boot wiring
+
+Primary validation artifact:
+- docs/dev/reports/samples2tools_batch_51_validation.txt (PASS)
