The core spec-driven-development preset’s change.adoc now carries a five-field template (Rationale, Outcome, Out of Scope, Open Questions, Notes), but tracer-spec extends minimal and owns its own guidance.

tracer-spec’s change role keeps the established three fields (Rationale, Outcome, Out-of-scope), matching CHG-004 and the current skill fallback.

tracer-spec and the core preset diverge on the change field set. The skill follows whatever the guidance declares, so divergence is tolerated, and Open Questions and Notes can be added later as growth.
