description: "A commit -m body carrying literal \\n characters glues the co-author trailer mid-line; ci-notify's line-anchored sed never sees it, so attribution silently drops to doyle-only"

Measured 2026-08-19 (od dump of raw bodies): four hertz commits carried the two LITERAL
characters `\` `n` twice before `Co-authored by: hertz` — the trailer rode the same line as
the body's last sentence. `ci-notify.sh:194` parses `^Co-authored by:` (line-anchored), so
the glued form is structurally invisible: CI verdicts notify doyle only, no error anywhere.

**Why:** the composing tool passed `"\n"` inside ONE single-quoted `-m` argument that never
expanded. **How to apply:** audit with `git log --format=%B | grep -E '^Co-authored by: '`
per commit (anchored) — the unanchored grep matches the glued form and hides the defect.
Fix = message-only reword; verify by TREE-ID equality (`git rev-parse <sha>^{tree}`), which
makes every prior measurement carry. Sweep the WHOLE chain population when one is found
(4/39 here, one authoring session's habit). Kin: [[relay-is-not-the-gaters-word]] for
verifying the reword yourself; the AGENTS.md trailer-audit mandate (never `%(trailers:)`).
