Evaluation protocols

methodology + evaluation protocol = performance. A protocol carries everything that shapes a number but is not part of the strategy: the trading calendar, transaction costs, execution lag, walk-forward grid, sealed holdout and data snapshot. Each is versioned and hashed, because changing any of them reprices every result measured under it.

The runner truncates the panel before execution, so the sealed period is unreachable rather than merely unreported. It opens once, by a logged event.

Trading calendars

A calendar is a referenced artifact, not a string. Holidays are expressed as rules — fixed dates with weekend observance, nth-weekday, and Easter-relative — so they can be checked against a published exchange schedule.
