The alibi that breaks

OSINT Difficulty Medium ~5 min +10 XP

At 02:14 UTC someone used a shared CI token to force-push the release branch and made 214 commits of history unreachable. Only four engineers hold that token, and all four gave an account of their night. Three of those accounts are corroborated by records that none of them controls: an airline manifest, a badge export, a voice bridge log. The fourth is backed only by evidence the person produced themselves, and that evidence does not survive being checked. Do not look for a confession, look for the statement the artifacts contradict. Submit the username of the engineer whose alibi breaks.
