+# fix/context-group-title
+
+## Context Group Header Rendering
+
+Prevent group headers from resolving plain strings as file links. Only explicit links or values that look like file paths are resolved, so context values like "STY" stay intact.
+
+Examples (illustrative):
+
+- Current: contexts = "STY" and a file `sty.md` exists with `title: Foo` -> header shows "Foo" (linked).
+- Target: contexts = "STY" always shows "STY" as plain text.
+
+## Changelog
+
+- Treat non-link, non-path group titles as plain text.
+- Keep file link rendering for explicit wiki/markdown links and path-like values.
+
+## Tests
+
+- `npm run i18n:sync`
+- `npm run lint` (warnings only; matches upstream)
+- `node generate-release-notes-import.mjs`
+- `npm run typecheck`
+- `npm run test:ci -- --verbose` (fails: `due-date-timezone-inconsistency.test.ts`, also failing in upstream)
+- `npm run test:integration`
+- `npm run test:performance`
+- `npm run build` (warns about missing OAuth env vars)
+- `npm run test:build`
