Both review points were factually right and my original text was wrong.
1. `git config format.signOff true` — which I had recommended as the *better*
option — only defaults the -s flag for `git format-patch`. `git commit` never
reads it, and there is no `commit.signoff` equivalent. Verified all three in a
throwaway repo: format.signOff → no trailer; commit.signoff → no effect; a
prepare-commit-msg hook → works. Shipping that advice would have been worse
than saying nothing, since it looks like a fix and silently changes nothing.
Now recommends `git commit -s`, gives the verified hook for automation, and
names format.signOff explicitly as a trap — the name invites exactly the
mistake I made, so it is worth warning about rather than omitting.
2. The DCO app's empty remediation-commit flow needs
`allowRemediationCommits.individual`. This repo ships no DCO config, so it
runs with that disabled and the original unsigned commits keep failing. The
escape hatch I offered does not exist here; rewriting is the only repair, so
the text now says to coordinate before rewriting shared history instead.
Mirror updated with both corrections.
