The forged ledger line points to a narrow time window. Three independent systems recorded the breach, but each system only preserved a residue of the minute after midnight.

The breach minute t is between 00:00 and 02:00, measured as minutes after midnight.

t mod 5 = 3
t mod 7 = 6
t mod 11 = 6

Find the event in the log that happened at that minute. The flag is the user.
