All new features work correctly and produce meaningful output. + +Engine parity is **100%** — native and WASM produce identical nodes, edges, and quality metrics. Native is 4.2x faster overall (241ms vs 1,009ms), with parsing 4.9x faster and complexity 47x faster. + +All 28 commands work correctly in both cold-start and post-build scenarios. Edge case handling is solid. Incremental rebuild is fast and accurate. The edge-drop bug from previous versions appears to be fixed. The programmatic API (`import('@optave/codegraph')`) loads cleanly with 99 exports. + +**Rating: 8.5/10** — A strong release with broad new functionality, solid engine parity, and no bugs found.
