Explores the diff-based approach (TypeBox Value.Diff → graphology mutation mapping) as an alternative to rebuild-on-change. Key findings: - The diff must happen at the graph level, not the source level, because TaskInput.dependsOn doesn't directly map to edge mutations - graphology's import(merge=true) handles merges but not deletions - The real win is reactivity (fine-grained event notifications), not performance - For <200 node graphs, rebuild is always sub-millisecond - A hybrid approach (diff for attribute-only changes, rebuild for structural changes) is possible but adds significant complexity Decision: defer to v2. ADR-002 (rebuild) stands. The exploration is preserved for future reference.
