Every node can be questioned.
USNow is built as a map: personal, social, political, historical, and further back. The Log is where that map stays open.
Each entry is filed to the record with its topic, node, date, and status. Some entries may correct information. Some may add context. Some may point to sources, contradictions, omissions, or connections that belong somewhere else in the structure.
The purpose is not noise. The purpose is a permanent, searchable public record of what people noticed, challenged, added, remembered, or refused to let disappear.
