Vauntico Sovereign Assessment Framework v2.1

TrustScore Methodology

The Financial TrustScore is a probability model of software reliability over the next operating window, not a raw bug counter. The score is normalized to 0-850 for portability across institutions.

1. Point Allocation (0-850)

Security

297pts (35%)

RLS posture, exposure risk, and unresolved vulnerability pressure.

Health

212pts (25%)

Dependency freshness, stale logic burden, and maintenance quality.

Uptime

170pts (20%)

Heartbeat stability, cron success rates, and operational continuity.

Velocity

171pts (20%)

Commit cadence, merge quality, and sustained delivery throughput.

2. Reliability Probability Model

Each pillar is transformed into a bounded quality factor in [0,1]. We then apply weighted priors calibrated from observed production behavior.

P(reliable | evidence) ~ wS*QS + wH*QH + wU*QU + wV*QV
where wS=0.35, wH=0.25, wU=0.20, wV=0.20

The posterior reliability probability is mapped to points: score = round(850 * P). This means a TrustScore of 680 represents materially higher reliability probability than 340, not merely half the number of issues.

3. Why This Is Institutional Grade

  • Signal fusion: security, quality, uptime, and velocity interact.
  • Normalization: every feature is bounded before weighting.
  • Auditability: every score can be traced to a snapshot timestamp.
  • Portability: 0-850 is consistent across verification pages and reports.
