Git reads trailers only from a block at the very end of a commit message. A squash merge concatenates the branch's messages, so every trailer but the last ends up mid-message, and an indented trailer is skipped as well. Both forms are real attributions and both are invisible to the trailer parser, which is what the project has been using to answer which agents touched a file. The script reads whole commit bodies instead. It groups by value, or lists one line per commit with --list, and takes a revision and a path the way git log does. On dev it reports 163 attributions where the trailer parser reports 122, so a quarter of the record was unreachable. The difference is entirely squashed and indented trailers, not new commits.
