- Rename FTMO_* constants → generic names (RISK_PER_TRADE, MAX_DAILY_LOSS, etc.) - Rename backtest_signal_ftmo → backtest_signal_risk - Rename _apply_ftmo_mask → _apply_risk_mask - Clean all FTMO/riskMgmt mentions from commit messages via filter-branch - AGENTS.md: add non-negotiable rule — NEVER mention proprietary terms in commits/releases - Code variables and function names sanitized project-wide - Force-pushed rewritten history to remote

- Portfolio Optimization (P7)
|
||
- Full Pipeline End-to-End
|
||
- Parallelization
|
||
- RiskMgmt Compliance
|
||
|
||
At least 20 integration tests covering all new features.
