Ad canaries (EasyList)

Twelve ad domains derived from EasyList: of the rules that block a domain outright (||domain^, with or without $third-party), the twelve whose names hash lowest under SHA-256, so nobody chose them and the set moves only when the list drops one or gains a name that hashes lower. The network check (M12.3) resolves them through the LAN resolver and does nothing else with them. Checked weekly; the list itself moves several times a day.
