+makes changes reviewable, testable, and honest: a reader should be able to
+understand why a change exists, what the correct behavior is, and exactly how
+to verify it, without reading the diff first.
+
+## When the OpenSpec format is required
+
+The format applies to **feature changes**: anything that adds or alters a
+requirement or user-visible behavior. A change is treated as a feature when
+its title uses the conventional `feat:` prefix or its branch starts with
+`feat/`.
+
+Everything else is exempt and needs no spec sections: `docs:`, `chore:`,
+`fix:`, `ci:`, `test:`, `refactor:`, `style:`, `build:`, and `perf:` changes,
+along with bug reports and other non-feature issues. Write a plain Summary /
+Changes / Verification body for those. Forcing requirement language and
+GIVEN/WHEN/THEN scenarios onto a docs typo or a dependency bump adds noise,
+not clarity.
