85+8.5
How it adds up: composite = Σ(score × weight) / Σ(weight) across measured + heuristic pillars only. Pending and data-rights-blocked pillars are excluded from both numerator and denominator. Total contributing weight = 50.0 of 100.0; the remaining 50.0 is unmeasured.
Caveat: 3 pillars not assessed yet; the score will recompute as the substrate fills in.
