AI Vendor Risk Heatmap: Staleness Decay & Audit Timeline

Organizations that build on third-party AI models inherit governance risk from every vendor in the chain — and that risk does not stay fixed once a contract is signed. This 2D dashboard renders the same fixed-inherent-risk-plus-evidence-staleness model as a scrolling per-vendor risk heatmap, a staleness-vs-posture phase plot with a live threshold boundary, and a portfolio-wide risk histogram. Tune the audit cadence, the balance between inherent posture and staleness, the risk-tolerance threshold and the simulation speed, then watch scheduled audits, on-demand audits, and direct row-click audits pull individual vendors — and the whole portfolio average — back under control.
