+# First Manifest Driven Playable Scene
+
+PR: PR_26152_198-first-manifest-driven-playable-scene
+Date: 2026-06-02
+
+## Scope
+
+- Added the first manifest-driven playable scene assembly.
+- Uses manifest config for terrain, objects, environment, rules, input, rendering, and frame timing.
+- Does not depend on samples or hard-coded game behavior.
+
+## Validation
+
+Command:
+
+```powershell
+node tests/engine/FirstManifestDrivenPlayableScene.test.mjs
+```
+
+Result: PASS.
+
+## Lanes Executed
+
+- engine - manifest-driven scene assembly validation.
+- runtime - first integrated headless playable scene only.
+
+## Lanes Skipped
+
+- samples - permanently out of scope.
+- browser Playwright - not part of this requested validation.
+
+## Playwright
+
+Playwright impacted: No browser/tool UI impact. This slice validates manifest-driven scene assembly through targeted Node tests.
+
+## Manual Validation
+
+Review the test to confirm the scene uses only manifest config and rejects missing object instances instead of using hidden defaults.
+
+## Blocker Scope
+
+No blocker for first manifest-driven playable scene.
