CLAUDE: Session 1 cleanup complete - Parts 4-6
Completed remaining Session 1 work:
Part 4: Remove offensive approach field
- Removed `approach` field from OffensiveDecision model
- Removed approach validation and validator
- Updated 7 backend files (model, tests, handlers, AI, validators, display)
Part 5: Server-side depth validation
- Added walk-off validation for shallow outfield (home batting, 9th+, close game, runners)
- Updated outfield depths from ["in", "normal"] to ["normal", "shallow"]
- Infield validation already complete (corners_in/infield_in require R3)
- Added comprehensive test coverage
Part 6: Client-side smart filtering
- Updated DefensiveSetup.vue with dynamic option filtering
- Infield options: only show infield_in/corners_in when R3 present
- Outfield options: only show shallow in walk-off scenarios
- Hybrid validation (server authority + client UX)
Total Session 1: 25 files modified across 6 parts
- Removed unused config fields
- Fixed hit location requirements
- Removed alignment/approach fields
- Added complete depth validation
All backend tests passing (730/731 - 1 pre-existing failure)
Next: Session 2 - Offensive decision workflow refactor (Changes #10-11)
