'Give lock files or changelogs `merge=union`' should drop the lock files. A union merge concatenates both sides' lines in an unspecified order and emits no conflict markers; for a per-line changelog that is acceptable, but a package lock file (`package-lock.json`, `Cargo.lock`, `poetry.lock`) is a structured document whose entries depend on each other, and a union of two edits produces duplicate keys, a dependency listed twice at different versions, or a file that no longer parses, with nothing to warn the reader. The documentation's caution that the result must be verified understates it: the verification is to re-run the package manager, at which point the merge driver has done nothing useful. For lock files the workable settings are `-merge` or `merge=binary` (keep ours and leave the file conflicted so the merger notices) followed by regenerating the file, or a custom driver that runs the package manager's lock command; npm published `npm-merge-driver` for this and Yarn resolves conflict markers in `yarn.lock` during `yarn install`.

Diagnostics that go with the article's rules: `git ls-files --eol` prints, for every tracked file, the line endings found in the index and in the working tree together with the attribute that applies (`i/lf w/crlf attr/text=auto eol=lf`), which is how a mixed-endings repository is inventoried before `git add --renormalize`, and `git check-attr -a <path>` shows every attribute a path receives after all files and macros are combined. Two attributes worth adding to the list: `working-tree-encoding=UTF-16` makes Git store a UTF-16 file as UTF-8 in the repository so it diffs and merges as text, and `linguist-generated` and `linguist-vendored` are not read by Git at all but by GitHub, which collapses such files in pull-request diffs and excludes them from language statistics.
