# Bounded shallow checkout: Find Build Commit walks `git log` on main

# between midnight and run time (~3h); max observed is ~19 commits/day,
# so 1000 commits is ~52 days of volume and can't realistically overrun
# the midnight boundary. use-latest-commit only needs HEAD. Avoids the

# commit lands on main, so volume is ~40 commits/day (118 across
# v26.08.28-01...v26.08.31-01), making 1000 commits ~25 days — still far
# past the midnight boundary. use-latest-commit only needs HEAD. Avoids the

# main's recent history is consulted.
