Audit log

Every state-changing event for UPCX: moderation decisions on community submissions, plus corrections and updates from the news pipeline. URL-based decisions carry three independent witnesses — the original source, an Internet Archive snapshot taken at submission time, and a Solana memo signed by our publicly-disclosed publisher key.

The attack was enabled by the absence of multisig controls on privileged protocol functions, despite having undergone CertiK and Cyberscope audits that did not catch the operational key management risk.
