Merged
Conversation
- Symbolic argv: - Keep argc concrete; only argv content bytes are symbolic - Rename CLI flag to --num-symbolic-args (keep --symbolic-argc as alias) - Add tests verifying stack layout, pointers, argc, a0, and null termination - Visualizer improvements: - Fix witness playback with carry-forward for empty steps - Add changed-node highlighting in graph - Show previous → new values in trace panel - Fix transitive collapse behavior - Optimize playback (avoid unnecessary re-renders) - Handle SVG export failures gracefully
