Incremental rebuilds drop from 466ms to 67–80ms, and bulk inserts for nodes, edges, roles, AST nodes, CFG, and dataflow all run through the native engine. better-sqlite3 is now lazy-loaded only as a fallback.

The decomposition improved MI from 5 to 13.4 but it needs further splitting -- the core partition loop is still monolithic. + +2. **computeFunctionComplexity** (cognitive 103) was not decomposed in this run. It is the second-worst function and should be a priority target. + +3. **Native extractor duplication** -- The `walk_node_depth` pattern is still duplicated across 9 extractors. A Rust macro or trait-based dispatch could reduce total cognitive complexity by ~800 points. This is the single highest-leverage refactor remaining. + +4. **Type-only export resolution** -- The codegraph limitation with TypeScript type-only exports inflates dead symbol counts. Fixing this in the resolution engine would improve quality score. + +5. **Batch sizing** -- Keep RECON batches to 5 files max for better audit granularity. + +6. **CLI and test domains** were excluded from this run. A future Titan run scoped to `src/cli/` could improve the tangled CLI layer (cohesion 0.299).
