It seems like $logs can also be of type null; however, hiqdev\chkipper\history\GitLogParser::parseLines() does only seem to accept array, maybe add an additional type check?

            $note = $this->matchNote($m[4]);
            if ($tag) {

The expression $tag of type string|null is loosely compared to true; this is ambiguous if the string can be empty. You might want to explicitly use !== null instead.

                $this->addTag($tag, $m[3]);
            }
