Trading Journal
A trading journal structure for Turtle-style execution review and rule maintenance.
A trading journal turns execution into evidence. Without records, it is difficult to know whether a poor period came from system behavior, market conditions or trader error.

Rule version record
When a strategy rule changes, record the version, effective date, reason, backtest window, out-of-sample window and expected risk impact. Rules can evolve, but changes need evidence.
