+# Gap Closure Plan 1: Fix PersonalityLearner Initialization
+
+**Objective:** Add missing AdaptationRate import to enable PersonalityLearner instantiation
+
+**Gap Closed:** Missing AdaptationRate import blocking PersonalityLearner initialization
+
+## Deliverables
+
+1. AdaptationRate imported in src/memory/__init__.py
+2. AdaptationRate included in __all__ export list
+3. PersonalityLearner can be instantiated without NameError
+
+## Tasks Completed
+
+| Task | Status | Commit | Description |
+|------|--------|--------|-------------|
+| 1. add-missing-import | ✓ | 3c0b8af | Added AdaptationRate to import statement |
+| 2. verify-import-chain | ✓ | bca6261 | Verified AdaptationRate in __all__ list |
+| 3. test-personality-learner-init | ✓ | d082ddc | Tested PersonalityLearner instantiation |
+
+## Key Changes
+
+- **File:** src/memory/__init__.py
+- **Changes:**
+  - Line 22: Added `AdaptationRate` to import from `.personality.adaptation`
+  - Line 874: Added `AdaptationRate` to __all__ export list
+- **Result:** PersonalityLearner(None) now instantiates successfully without NameError
+
+## Verification
+
+✓ AdaptationRate import added to line 22
+✓ AdaptationRate in __all__ export list (line 874)
+✓ PersonalityLearner(None) completes without NameError
+✓ PersonalityLearner with AdaptationRate config instantiates correctly
+✓ No new errors introduced
+
+## Technical Details
+
+The fix resolved a NameError that occurred when PersonalityLearner.__init__() attempted to use `AdaptationRate` on line 56 to configure the learning rate. The enum is defined in `src/memory/personality/adaptation.py` with three values:
+- SLOW = 0.01 (Conservative, stable changes)
+- MEDIUM = 0.05 (Balanced adaptation)
+- FAST = 0.1 (Rapid learning, less stable)
+
+The import chain now correctly exposes AdaptationRate for both internal use within the module and external imports via `from src.memory import AdaptationRate`.
+
+## Testing Results
+
+All instantiation tests passed:
+- Basic instantiation with None memory_manager
+- Instantiation with AdaptationRate enum configuration
+- Instance validation (not None assertion)
+- No NameError or other exceptions raised
+
+The personality learning pipeline is now unblocked and functional.
