Graph Evolution

Builds code graphs at two git snapshots and diffs them structurally, not just textually. You get new attack paths, blast radius growth, taint propagation changes, and privilege boundary shifts that regular git diff won't show. It wraps Trailmark's graph analysis, runs pre-analysis on both snapshots, then combines native structural diff with subgraph membership changes. Use it when reviewing what changed between releases or audit snapshots, especially if you care about security evolution rather than just line changes. The workflow is explicit: git worktrees, graph builds, dual diff commands, then interpretation. It won't replace your text diff, but it catches the transitive complexity and call graph mutations you'd otherwise miss.
