About Sourced Signal
An independent publication by Harrison, covering national security, economic statecraft, defense capacity and AI infrastructure.
Sourced Signal follows decisions and developments that change policy, industrial capacity or geopolitical risk. The aim is a selective reading of the evidence, with source links and uncertainty kept visible.
Models help organize and draft material from selected public sources. The Watch separates reviewed analysis from labeled automated previews of official records. Crisis entries receive human review. The Daily Brief uses automated screening and quality checks; it is not individually signed off by an editor on every run.
Harrison maintains the publication, reviews withheld material and handles corrections. Read the methodology or get in touch.
