-## 🔴 Critical Issues (Migration Blockers)
+## ✅ **RESOLVED ISSUES** (Phase 2 - NULL Constraints)

-### CONSTRAINT-CURRENT-BSTATCOUNT-001 🆕
- **Priority**: CRITICAL
- **Table**: current
- **Error**: `null value in column "bstatcount" violates not-null constraint`
- **Impact**: Blocks current table migration (11 records affected)
- **Status**: IDENTIFIED
- **Solution**: Make field nullable or set default value
+### CONSTRAINT-CURRENT-BSTATCOUNT-001 ✅
+- **Resolution**: Made `bstatcount` field nullable (`null=True`)
+- **Date Resolved**: 2025-08-18
+- **Root Cause**: 2 out of 11 current records have NULL batting stat counts
+- **Solution Applied**: Schema change in db_engine.py line 163
+- **Test Result**: ✅ current table now migrates (11 records)

-### CONSTRAINT-CURRENT-PSTATCOUNT-001 🆕
- **Priority**: CRITICAL (Predicted)
- **Table**: current  
- **Error**: `null value in column "pstatcount" violates not-null constraint` (likely)
- **Impact**: Blocks current table migration (11 records affected)
- **Status**: PREDICTED
- **Solution**: Make field nullable or set default value
+### CONSTRAINT-CURRENT-PSTATCOUNT-001 ✅

-### CONSTRAINT-TEAM-AUTO_DRAFT-001 🆕
- **Priority**: CRITICAL
- **Table**: team
- **Error**: `null value in column "auto_draft" violates not-null constraint`
- **Impact**: Blocks team table migration (546 records affected)
- **Status**: IDENTIFIED
- **Solution**: Make field nullable or set default value (False)
+### CONSTRAINT-TEAM-AUTO_DRAFT-001 ✅
+- **Resolution**: Made `auto_draft` field nullable (`null=True`)
+- **Date Resolved**: 2025-08-18
+- **Root Cause**: ALL 546 team records have NULL auto_draft values (unpopulated feature)
+- **Solution Applied**: Schema change in db_engine.py line 282
+- **Test Result**: ✅ team table now migrates (546 records)
+
+### CONSTRAINT-CURRENT-BET_WEEK-001 ✅ (Bonus Discovery)
+- **Resolution**: Made `bet_week` field nullable (`null=True`)
+- **Date Resolved**: 2025-08-18
+- **Root Cause**: 2 out of 11 current records have NULL betting week values
+- **Solution Applied**: Schema change in db_engine.py line 165
+- **Test Result**: ✅ current table migration improved
+
+### CONSTRAINT-TEAM-GMID-001 ✅ (Bonus Discovery)
+- **Resolution**: Made `gmid` field nullable (`null=True`)
+- **Date Resolved**: 2025-08-18
+- **Root Cause**: 9 out of 546 team records have NULL gmid (Free Agents have no Discord ID)
+- **Solution Applied**: Schema change in db_engine.py line 270

+## 🔴 Critical Issues (Migration Blockers) - REMAINING

 ### SCHEMA-CUSTOMCOMMANDCREATOR-MISSING-001
 - **Priority**: CRITICAL
 - **Table**: customcommandcreator
 - **Error**: `no such table: customcommandcreator`
 - **Impact**: Table doesn't exist in SQLite source
