+# PR_26180_OWNER_017 src Dissection and Demo Cleanup Report
+
+## Executive Summary
+
+PR_26180_OWNER_017 removes the local ignored demo artifact `assets/DemoGame-26168-001.gfsp`, removes the now-empty `assets/` shell, and audits every tracked file under `src/`.
+
+No tracked `src/` files are moved in this PR. The file-by-file audit assigns proposed destinations, but most files require scoped reference migrations to preserve runtime behavior.
+
+## Demo Artifact Cleanup
+
+- Deleted local ignored artifact: `assets/DemoGame-26168-001.gfsp`.
+- Removed `assets/` after the artifact deletion left the folder empty.
+- No tracked files were deleted.
+- No active `assets/DemoGame-26168-001.gfsp` path references remain outside reports/workspace.
+
+Filename-only `DemoGame-26168-001.gfsp` references remain in Playwright tests as generated-download assertions. Those are not references to the deleted root file path.
+
+## src Audit Summary
+
+Tracked `src/` files audited: 596.
+
+The detailed file-by-file audit lives at:
+
+`dev/reports/PR_26180_OWNER_017-src-dissection-and-demo-cleanup_src-file-destination-audit.md`
+
+## src Move Decision
+
+No `src/` files moved.
+
+Reason:
+
+- `src/` content is actively referenced by `www/`, `api/`, `dev/tests/`, and `dev/tools/`.
+- Moving `src/` files requires scoped import/reference updates.
+- The PR request requires preserving runtime behavior.
+- Uncertain or mixed-ownership files must be documented before movement.
+
+## Proposed Follow-Up PRs
+
+1. Browser API client migration: move `src/api/` browser clients to a browser-owned location.
+2. Engine runtime migration: move `src/engine/` to the final browser/runtime source layer.
+3. Shared contract/schema migration: split `src/shared/contracts/` and `src/shared/schemas/` into the API contract surface.
+4. Shared utility migration: split `src/shared/` browser/runtime utilities by actual import ownership.
+5. Legacy Admin Notes retirement: migrate or retire `src/dev-runtime/admin/`.
+
+## Runtime/Product Impact
+
+No runtime behavior changed. No product code changed. No API/database behavior changed.
