+# PR_26140_069 Engine Domain Index Barrel Removal Phase 3
+
+## Summary
+- Removed the targeted phase 3 engine domain barrel files:
+  - `src/engine/ai/index.js`
+  - `src/engine/animation/index.js`
+  - `src/engine/automation/index.js`
+  - `src/engine/config/index.js`
+  - `src/engine/ecs/index.js`
+  - `src/engine/entity/index.js`
+  - `src/engine/interaction/index.js`
+- Replaced active imports from those barrels with direct canonical file imports.
+- Kept edits to import wiring only. No runtime logic, sample JSON, game/sample entry removal, replacement barrels, or pass-through shims were added.
+- No edits were made under `src/engine/debug/**`, `src/engine/network/**`, or `src/engine/systems/**`.
+- `src/engine/core/index.js` remains untouched in this PR.
+- `src/engine/release/SettingsSystem.js` received a required import-only update from the config barrel to `src/engine/config/ConfigStore.js` so the config barrel could be deleted.
+
+## Direct Import Mapping
+- AI:
+  - patrol helpers -> `src/engine/ai/PatrolSystem.js`
+  - pathfinding -> `src/engine/ai/GridPathfinding.js`
+  - chase/evade steering -> `src/engine/ai/SteeringBehaviors.js`
+  - `AIStateController` -> `src/engine/ai/AIStateController.js`
+  - group behavior helpers -> `src/engine/ai/GroupBehaviors.js`
+- `AnimationController` -> `src/engine/animation/AnimationController.js`
+- Automation classes -> their one-class files under `src/engine/automation/`
+- `ConfigStore` -> `src/engine/config/ConfigStore.js`
+- `World` -> `src/engine/ecs/World.js`
+- Entity components -> their one-class files under `src/engine/entity/`
+- Interaction helpers -> `src/engine/interaction/InteractionSystem.js`
+
+## Additional Import Validation Repair
+- While validating changed-file imports, `tests/final/EditorAutomationSecurityPipeline.test.mjs` surfaced stale imports from removed `tools/shared/editor/index.js` and `tools/shared/pipeline/index.js`.
+- Because that test was already touched for automation barrel removal, it was updated with direct canonical imports from the existing editor and pipeline files so the requested changed-file import validation and affected domain test can run cleanly.
+
+## Validation
+- PASS: target barrel scan reports `0` active imports/exports from the seven phase 3 barrels.
+- PASS: target deletion scan confirms all seven targeted `index.js` files no longer exist.
+- PASS: no JSON files changed.
+- PASS: `node --check` passed for 42 changed existing JS/MJS files.
+- PASS: local import target validation passed for 42 changed existing JS/MJS files.
+- PASS: `npm run test:workspace-v2` passed 59/59 tests.
+- PASS: targeted affected domain tests passed:
+  - `tests/ai/AIBehaviors.test.mjs`
+  - `tests/final/EditorAutomationSecurityPipeline.test.mjs`
+- PASS: `git diff --check` exited 0. Git emitted advisory line-ending warnings for touched `.mjs` test files only.
+- SKIPPED: full samples smoke test, per PR instruction.
