Signals are linked to their original public sources. Activity and decay are shown only where repeated observations support them.
Detect. Track. Analyze. Act.
FWA uses repeated public-source observations to show measured activity. The activity change compares the last two valid observed intervals, normalized to points per hour. A state can reflect the observed peak, so state and latest change may differ. When data is insufficient, the index shows “Insufficient data” instead of a guessed percentage. Bookmark and share signals yourself; FWA never auto-posts.
