Formatting was clean through53288116and then drifted across three commits on 2026-07-30:1bf7aac7left one source unformatted,f13f5af6a second, anddaab4f1efour more. CI's Verify formatting job checks the whole tree, so it has had six files to report ever since. No pre-commit hook is installed in this checkout, so the aggregate check never ran locally to catch them. Formatted with the dart_style revision Dart 3.12.0 bundles, which is what the pinned Flutter 3.44.0 CI toolchain runs, rather than with a newer local SDK; the two disagree about some argument-list splits. The current stable formatter accepts this result as well, so both report the tree clean.
