Not sure why but you seem to be the author of the "fast-import: add 'strip-if-invalid' mode to --signed-commits=<mode>" commit now:

$ git cat-file commit 6c723ad30a3f77787e2247f52d62fa462a24cf68 tree 68ab2d63f36af2854b3e49c563bd213fea1357a6 parent cb034c020aba54360e7c19faf82021399bf131e7 author Junio C Hamano <gitster@pobox.com> 1763355463 -0800 committer Junio C Hamano <gitster@pobox.com> 1763355463 -0800

fast-import: add 'strip-if-invalid' mode to --signed-commits=<mode>

Tools like `git filter-repo`[1] use `git fast-export` and `git fast-import` to rewrite repository history. When rewriting history using one such tool though, commit signatures might become invalid because the commits they sign changed due to the changes in the repository history made by the tool between the fast-export and the fast-import steps.
