- Fixed DQN early stopping checkpoint naming bug (Option B)
- Added is_final: bool parameter to checkpoint callback signature
- Trainer now distinguishes final checkpoints from regular epoch checkpoints
- Final checkpoints use 'dqn_final_epoch{N}' naming convention
- Regular checkpoints use 'dqn_epoch_{N}' naming convention
- Completed comprehensive TFT OOM investigation
- Spawned 3 parallel agents for memory analysis
- Identified 16.4GB memory leak (29.7x over expected 525-550MB)
- Root causes: Attention cache bloat (960MB), gradient accumulation bug, detached tensors
- Recommended fixes: Disable cache during training, explicit tensor drops
- Created TFT_MEMORY_ANALYSIS.md, TFT_MEMORY_LEAK_ANALYSIS.md
- DQN 100-epoch training VERIFIED on Runpod RTX A4000
- Training completed successfully: 100/100 epochs
- Final checkpoint created: dqn_final_epoch100.safetensors
- Training speed: 4.8 sec/epoch (3.5x faster than baseline)
- Option B fix working perfectly
- Deployed RTX 4090 pod for TFT testing
- Pod ID: 6244yzm9hadnog
- 24GB VRAM to bypass OOM issue
- EUR-IS-1 datacenter, $0.59/hr

Format: Terminal-friendly with box drawing characters
4. WARN_D1_INDEX.md (this file)
Navigation and context:
- Mission statement
- Deliverable descriptions
- Key findings
- Validation results
- Follow-up actions
Key Findings
Production Code: ✅ READY
- 7 warnings total (0 blockers)
- 0 compilation errors
- Affected crates: backtesting_service (6), trading_service (1)
- Categories:
- 71% Dead code (strategic mocks)
- 14% Unused imports
- 14% Style issues
- Fix time: 15 minutes (optional)
- Impact: ZERO production impact
Test Code: ⚠️ NEEDS ATTENTION
- 10 warnings in model_loader (fixable, 15 minutes)
- 30+ compilation errors in data_acquisition_service (2-4 hours)
- Impact: Test coverage reduced, some warnings hidden
Overall Assessment
- Production deployment: ✅ APPROVED (no blockers)
- Warning cleanup: Optional (cosmetic only)
- Test infrastructure: Needs separate cleanup sprint
Validation Results
Final Validation (2025-10-25 16:04):
cargo check --workspace --lib --bins
Production warnings: 7
Compilation errors: 0
Build status: ✅ SUCCESS
Comparison with CLAUDE.md:
- CLAUDE.md reports: "1,821 warnings"
- This scan found: 31 warnings (7 production + 24 test)
- Explanation: CLAUDE.md likely includes clippy pedantic warnings, historical data
Follow-Up Actions
Immediate (0 hours)
✅ APPROVED - Deploy production code as-is (zero blockers)
Short-Term (15 minutes) - OPTIONAL
WARN-D2: Production warning cleanup
- Auto-fix style issues:
cargo fix --lib -p backtesting_service trading_service - Mark 4 mock utilities with
#[allow(dead_code)] - Remove 1 unused import
- Investigate
init_loggingusage
Medium-Term (15 minutes) - OPTIONAL
WARN-D3: Test warning cleanup (model_loader)
- Remove 8 unused extern crate declarations
- Remove 5 unused imports
- Handle dead code in test utilities
Long-Term (2-4 hours)
WARN-D4: Fix data_acquisition_service compilation
- Investigate 30+ compilation errors
- Restore or recreate missing test utilities
- Fix missing type imports
- Re-scan for hidden warnings
