## 🚫 OUTSTANDING ISSUES (NON-BLOCKING)
|
|
|
|
### P1: 10 Quantization Test Failures
|
|
- **Status**: ⚠️ Isolated to TFT-INT8-QAT only
|
|
- **Impact**: Does NOT block production (other models operational)
|
|
- **Fix ETA**: 1-2 days (gradient checkpointing needed)
|
|
|
|
### P3: 94 Clippy Warnings
|
|
- **Status**: ⚠️ Code quality improvements only
|
|
- **Impact**: Zero functional impact
|
|
- **Fix ETA**: 2-4 hours (defer to post-production sprint)
|
|
|
|
### P4: Pre-existing Library Issues
|
|
- **Status**: ⚠️ Out of scope for current wave
|
|
- **Impact**: Blocks 5 integration tests (not core functionality)
|
|
- **Fix ETA**: 2-3 hours (separate task)
