Loaded workspace context (SOUL.md, USER.md, MEMORY.md).
BOOTSTRAP.md existed but the workspace was already initialized, so it was removed.
Started a focused quant-research continuation task in cyb50-quant.
Objective: run two concrete experiments using existing code where possible:
- multi-index dual-momentum rotation
- Chinext50 trend-following with cash/flat regime control
Required outputs: code/config updates, reproducible commands, actual backtest metrics, and a concise markdown summary saved in-repo.
