 ### 📍 Current Context
-**Week 7 Task 1 is complete!** We've implemented the async decision workflow infrastructure that integrates AI and human decision-making. The GameEngine now has `await_defensive_decision()` and `await_offensive_decision()` methods that use asyncio Futures for WebSocket communication. AI teams get instant decisions, human teams wait with timeout.
+**Week 7 Tasks 1 & 2 are complete!**
+- **Task 1**: Async decision workflow infrastructure with asyncio Futures for WebSocket communication
+- **Task 2**: Comprehensive validators for defensive and offensive decisions with 24+ test cases
 
-**Next up**: Validate those decisions! Task 2 adds `validate_defensive_decision()` and `validate_offensive_decision()` to the validators module to ensure decisions are legal for the current game state.
+**Next up**: Enhance the result chart system! Task 3 implements `StandardResultChart` with defensive/offensive decision modifiers, hit location logic, and ~25 test cases. This will allow decisions to actually affect play outcomes.

    - **Testing**: Config tests 58/58 passing ✅, Terminal client works perfectly ✅
 
-### 2. Manual Outcome Testing Feature (Bonus)
+### 2. Decision Validators (Week 7 Task 2) - 100%
+   - **Enhanced Validators** (`app/core/validators.py`)
+     - `validate_defensive_decision()` - Comprehensive validation:
+       - Validates all alignments (normal, shifted_left, shifted_right, extreme_shift)
+       - Validates all depths (infield: in/normal/back/double_play, outfield: in/normal/back)
+       - Validates hold_runners require actual runners on specified bases
+       - Validates hold_runners only on bases 1, 2, or 3
+       - Validates double_play depth requires runner on first
+       - Validates double_play depth not allowed with 2 outs
+     - `validate_offensive_decision()` - Comprehensive validation:
+       - Validates all approaches (normal, contact, power, patient)
+       - Validates steal_attempts only to bases 2, 3, or 4
+       - Validates steal_attempts require runner on base-1
+       - Validates bunt_attempt not allowed with 2 outs
+       - Validates bunt_attempt and hit_and_run cannot be simultaneous
+       - Validates hit_and_run requires at least one runner on base
+     - Clear error messages for all validation failures
+     - Follows "Raise or Return" pattern with ValidationError exceptions
+     - **Impact**: All decisions validated before resolution, prevents illegal game states
+
+   - **Comprehensive Tests** (`tests/unit/core/test_validators.py`)
+     - 24+ new test cases covering all validation logic
+     - 13 defensive decision validation tests
+     - 16 offensive decision validation tests
+     - Edge case coverage (0 outs, 1 out, 2 outs, various runner scenarios)
+     - All 54/54 tests passing ✅
+     - **Impact**: Full coverage of decision validation rules
+
+### 3. Manual Outcome Testing Feature (Bonus)
    - **Terminal Client Commands** (`terminal_client/commands.py`, `terminal_client/repl.py`)
      - Added `list_outcomes` command - Displays categorized table of all 30+ PlayOutcome values
      - Added `resolve_with <outcome>` command - Force specific outcome for testing
