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.

Its Pulse Index is 2.2 of 100, built from 2 of 4 observed signal families. Observed footprint: 4 tracked press mentions, 7 functional tags. It has no curated competitive-alternative edges yet, so the comparable set below is functional tag-similarity — read it with the confidence flags.

Confidence reflects source and category coherence: curated = an editorially linked alternative; similar = strong functional tag-overlap in the same category; tag-overlap = shared tags only and may be noisy. Pulse is the observed-activity index real; a dash means the comparable has no observed signal families.
