jgrusewski 61801cfd06 feat(deprecation): Complete deprecated code analysis and cleanup preparation

**Wave D Phase 6 - Technical Debt Cleanup (Agent C6)**

## Changes
- Identified deprecated code patterns across codebase
- Analyzed mock repository usage (strategically retained per AGENT_M13)
- Documented deprecation cleanup strategy
- Prepared deprecation removal todos

## Analysis Results
- Mock structs: RETAINED (strategic testing infrastructure)
- Never-read fields: 2 instances in backtesting_service
- Dead code warnings: 35 total across workspace
- databento_old references: None found in active code

## Status
- ✅ Deprecation analysis complete
- ⏳ Cleanup execution pending user confirmation
- 📊 Test impact assessment ready

Agent TEST-03: Quick Summary

Agent: TEST-03 - ML Package Test Validator Status: ⚠️ PARTIAL VALIDATION - Critical discrepancies found Date: 2025-10-18

🎯 Mission Outcome

Validated ML package tests with focus on Wave D regime detection (indices 201-224). Found significant discrepancies between CLAUDE.md claims and actual test results.

⚠️ Critical Findings

1. Test Count Mismatch

Claimed: 584/584 tests (100%)
Actual: 1,250 lib tests, ~1,567 total
Status: ❌ Claim is inaccurate

2. Test Pass Rate

Claimed: 100% (584/584)
Actual: 96.3% (1,509/1,567)
Failures: 43+ tests failing
Status: ⚠️ Good but not 100%

3. Performance Claims

Claimed: 432x faster than targets
Actual: Mixed results
- DQN: 5.5x slower than target
- PPO: 3.4x slower than target
- MAMBA-2: 2.5x slower than target
- TFT-INT8: 2.9x faster than target ✅
Status: ❌ Claim not validated

4. GPU Memory Budget

Claimed: 440MB (89% headroom on 4GB)
Actual: 2,500MB (62.5% usage)
TFT-INT8 alone: 2,000MB (16x over budget)
Status: 🔴 CRITICAL FAILURE

✅ What's Working

Wave D Core Features (100% Pass)

✅ Adaptive Features (221-224): 12/12 tests
✅ Transition Probability (216-220): 15/15 tests
✅ ADX Features (211-215): 15/15 tests
✅ E2E ES.FUT: 4/4 tests
✅ E2E NQ.FUT: 3/3 tests
✅ Edge Cases: 34/34 tests
✅ ML Model Input: 13/13 tests

Total: 96/96 tests passing (100%)

⚠️ What's Broken

Failed Test Categories

Category	Pass Rate	Issues
CUSUM Features	83.3% (25/30)	Window overflow bugs
Bayesian Changepoint	66.7% (12/18)	Edge cases
Trending Regime	72.0% (18/25)	Thresholds
Volatile Regime	60.0% (9/15)	Volatility calc
TFT Tests	0% (0/11)	API breakage

Root Causes

TFT: CheckpointMetadata API changes (11 tests)
CUSUM: Rolling window management bugs (5 tests)
Regime Detection: Edge case handling (21 tests)
Volume Bars: VolumeBarSampler API changes (9 tests)

📊 Accurate Test Status

ML Lib Tests:     1,223 / 1,250  (97.8%)
Wave D Core:         96 / 96     (100%)
Regime Detection:    95 / 121    (78.5%)
Integration:        ~95 / ~100   (~95%)
─────────────────────────────────────────
TOTAL:           ~1,509 / ~1,567 (96.3%)

Production Readiness: ⚠️ 95-96% (not 99.4%)

🔥 Immediate Action Required

P0 (Critical - Today)

✅ Document actual status (this report)
⚠️ Fix TFT CheckpointMetadata API (2-4 hours)

Document known failures

📈 Performance Reality Check

Model Inference (vs Targets)

Model	Target	Actual	Status
DQN	200 μs	1,093 μs	❌ 5.5x slower
PPO	324 μs	1,107 μs	❌ 3.4x slower
MAMBA-2	500 μs	1,239 μs	❌ 2.5x slower
TFT-INT8	3,200 μs	1,097 μs	✅ 2.9x faster

Memory Usage (vs Budget)

Model	Budget	Actual	Status
DQN	6 MB	150 MB	❌ 25x over
PPO	145 MB	200 MB	⚠️ 1.4x over
MAMBA-2	164 MB	150 MB	✅ Under
TFT-INT8	125 MB	2,000 MB	🔴 16x over
Total	440 MB	2,500 MB	🔴 5.7x over

🎓 Key Takeaways

Wave D core features are solid ✅
- 96/96 tests passing
- Adaptive, transition, ADX features work perfectly
Regime detection needs work ⚠️
- CUSUM window bugs
- Edge case handling in Bayesian/Trending/Volatile
TFT tests are broken ❌
