The 5 Design Principles Behind a Privacy Travel Kit

A deep dive into the five principles behind every component of the Communication Suite. P1: identity lives at the account layer, not the hardware layer, so swapping the phone but keeping the number changes almost nothing. P2: sever identity where it's created, once, on neutral ground: the first tower attach, account births and purchases. P3: enforcement belongs at the endpoint, not the perimeter. P4: minimise the number and lifetime of persistent identifiers. P5: the best-defended kit is the one not worth examining. One worked example for each (reuse, the build order, the phone's always-on VPN, the rotation policy and the Faraday bag), then five tempting shortcuts and the principle each one breaks.
