Trust here is actuarial, not vibes. Every module starts at 0.5 (no history is not the same as trustworthy), confirmed defects push trust down, and recency weighting uses a 720h half-life so a bug from last quarter matters less than one from yesterday — but the 0.3 floor means old sins never fully vanish. The caps (risk multiplier 3.0, prior 0.95) keep the math from ever reaching certainty. All of it feeds impact/predict so risk shows up where you are about to edit.
