realPulse Index
realEach family contributes its observed strength × weight to the 0–100 Pulse. Missing families contribute nothing and are never renormalized, so an unobserved product reads lower — Pulse measures observed activity, not potential.

generated from the observed metrics above · no external narrativeThe Chan Zuckerberg Initiative's listed site resolved live when we last probed it on Jul 4, 2026, so we mark it verified alive. Its Pulse Index is 45.0 of 100, built from 2 of 4 observed signal families. Observed footprint: 1 functional tag. It has no curated competitive-alternative edges yet, so the comparable set below is functional tag-similarity — read it with the confidence flags.
