Scientific pillar

A piece of established, evidence-based science collected in step 4b: what is actually known, never a speculative intervention.

Each carries a mechanism, a verified effect, a readiness level (RL-1 lab-validated, RL-2 human data or models, RL-3 clinically deployed), capabilities, a fragility score from 1 to 10, and its relationship to the goal. Scientific pillars are what the gap questions compare against requirements; the pillar provenance audit later checks whether the studies they cite can be found.
