AGENT 171: Quick Reference - Critical Blockers
Date: 2025-10-15 Status: ⚠️ HOLD ON MAMBA-2 TRAINING
Critical Blockers (Must Fix Now)
1. MAMBA-2 Matrix Multiplication Bug (P0)
Error:
shape mismatch in matmul, lhs: [B, S, 1024], rhs: [16, 1024]
Impact: 0/7 E2E tests passing (100% failure rate)
Location: ml/src/mamba/selective_state.rs or ml/src/mamba/mod.rs
Root Cause: RHS tensor has hardcoded first dimension (16) instead of dynamic batch size
Fix Needed:
// Search for matmul operations in Mamba2SSM::forward
// Fix tensor shapes to use batch_size variable
// Likely in out_proj, dt_proj, or B/C matrices
Test Command:
cargo test -p ml --test e2e_mamba2_training
# Goal: 7/7 passing
2. DQN State Dimension Mismatch (P1)
Error:
assertion `left == right` failed: State dimension should be 64
left: 52
right: 64
Impact: DQN training will fail
Location: ml/src/trainers/dqn.rs (test_features_to_state)
Root Cause: Feature engineering produces 52 features, model expects 64
Fix Options:
- Update DQN model config to accept 52 dimensions
- Expand feature engineering to 64 features
- Fix test to use correct dimension
Test Command:
cargo test -p ml --lib trainers::dqn::tests::test_features_to_state
# Goal: PASSED
3. Trading Service SQLX Compilation (P1)
Error:
error: `SQLX_OFFLINE=true` but there is no cached data for this query
Impact: Trading service won't compile
Location: services/trading_service/src/paper_trading_executor.rs (5 queries)
Root Cause: .sqlx/ cache incomplete after Agent 169's changes
Fix:
cd services/trading_service
export DATABASE_URL="postgresql://foxhunt:foxhunt_dev_password@localhost:5432/foxhunt"
cargo sqlx prepare
# Commit generated .sqlx/*.json files
Test Command:
cargo build -p trading_service
# Goal: Successful compilation
Test Results Summary
| Component | Status | Pass Rate | Blocker |
|---|---|---|---|
| MAMBA-2 E2E | FAILED | 0/7 (0%) | YES |
| ML Library | PARTIAL | 765/776 (98.6%) | DQN only |
| Trading Service | FAILED | Compilation error | YES |
Next Actions
Immediate:
- Agent 172: Fix MAMBA-2 matrix multiplication (1-2 hours)
- Agent 173: Fix DQN state dimension (30 min)
- Agent 174: Fix SQLX cache (15 min)
After Fixes: 4. Agent 175: Re-run full test suite (validate all fixes) 5. Agent 176: Launch MAMBA-2 training (ONLY if 100% pass rate)
Commands to Run After Fixes
# 1. Test MAMBA-2
cargo test -p ml --test e2e_mamba2_training
# Expected: 7/7 passing
# 2. Test DQN
cargo test -p ml --lib trainers::dqn::tests
# Expected: All passing
# 3. Build Trading Service
cargo build -p trading_service
# Expected: Successful compilation
# 4. Full Workspace Test
cargo test --workspace --features cuda --lib
# Expected: >99% pass rate
DO NOT START TRAINING UNTIL:
- MAMBA-2 E2E: 7/7 tests passing
- DQN state dimension: Test passing
- Trading service: Compiles successfully
- Full test suite: >99% pass rate
Estimated Time to Fix All Blockers: 2-3 hours
