Graph Evolution Builds Trailmark code graphs at two source snapshots and computes a structural diff. Surfaces security-relevant changes that text-level diffs miss: new attack paths, complexity shifts, blast radius growth, taint propagation changes, and privilege boundary modifications. When to Use - Comparing two git refs to understand what structurally changed - Auditing a range of commits for security-relevant evolution - Detecting new attack paths created by code changes - Finding functions whose blast radius or complexity grew silently - Identifying taint propagation changes across refact…
