Description

Is your feature request related to a problem? Please describe.

The features harness supports checking histories against static, in-repo saved histories. This is nice to ensure some form of backwards compatibility, but it easily breaks on genuinely compatible things too, like adding new fields to history events that aren't critical to replay.

Describe the solution you'd like

An easy way to mark certain fields as "it's ok if this is present in current history and not in stored static history"

Research direction

Start by locating the harness history checker and its comparison between current history events and stored static histories. Define how fields can be marked as optional when newly present, while differences in critical fields still fail compatibility checks. Done means compatible added fields can be ignored without weakening other history validation.
