removed +- `DbnDecoder::metadata()` → Use `metadata().clone()` +- `decode_record_ref()` → Use iterator-based API + +**Effort**: 2-4 hours manual API migration + +--- + +#### Step 2: Single-Day Test

Level-2 data acquisition cost ($12-$25) is prohibitive +- If 3.5-day GPU training time is unacceptable +- If rules-based prediction performance sufficient +- If other models (DQN, PPO) provide sufficient signal + +--- + +### Option C: Wait for Agent 82 (Not Recommended) + +**Issue**: Agent 82 doesn't exist and was likely skipped/merged + +**Evidence**: +- No AGENT_82 artifacts in codebase
