Signal Bureau
Signal Bureau maintains source-backed entity and event state for AI systems and the people who direct them: what changed, what it changed from, and the receipt behind it — refreshed daily with intraday updates across defense, space, health and biopharma, geopolitics, and markets. Humans get the clear read; machines get the same truth as structured data.
