Three docstrings dated their measurement to `59003d5a3`, this branch's head before
it was rebased onto `main` after ersatztv#907 landed. That commit is unreachable
from the branch and will never be in `main`, so `git show` on it fails for every
later reader — a citation that cannot be followed is worse than none, because it
reads as checkable. Each now names what it measured against ("the predecessor of
this commit", and for the guard, "as it walked `jobs.<id>` only and compared
per-file NAME SETS"), which is what the reader actually needs and what survives
any rebase.
