+### 9.4 Superseded-PR Commit Template (Recommended)
+
+When a commit unifies or supersedes prior PR work, use a deterministic commit message layout so attribution is machine-parsed and reviewer-friendly.
+
+- Keep one blank line between message sections, and exactly one blank line before trailer lines.
+- Keep each trailer on its own line; do not wrap, indent, or encode as escaped `\n` text.
+- Add one `Co-authored-by` trailer per materially incorporated contributor, using GitHub-recognized email.
+- If no direct code/design is carried over, omit `Co-authored-by` and explain attribution in the PR body instead.
