Hub target = most-connected node. +**Note (3.9.0):** The ↑177-184% fnDeps regression (9.7ms → 27ms) reflects substantial codebase growth between 3.7.0 and 3.9.0 — many new language extractors were added across 3.7.0-3.8.0 (Elixir, Lua, Dart, Zig, Haskell, OCaml, F#, Gleam, Clojure, Julia, R, Erlang, C, C++, Kotlin, Swift, Scala, Bash, Solidity, Objective-C, CUDA, Groovy, Verilog), significantly increasing the `buildGraph` hub node's edge count. The `findCallersBatch` path was also refactored in 3.8.1 (PR #815). fnImpact and diffImpact grew only 8-14%, consistent with normal expansion. The native engine being marginally slower than WASM for fnDeps (27.4ms vs 26.9ms, ~2%) is within measurement noise and not a meaningful inversion. Versions 3.8.0 and 3.8.1 are absent because their query benchmark data was removed — v3.8.1 was measured before the `findCallersBatch` fix and showed artificially inflated fnDeps latencies; v3.8.0 had no separate query benchmark run. + **Note (3.6.0):** Native deltas are relative to 3.4.1 (the last version with native data; 3.5.0 was wasm-only). The mid-query target changed from `db` (3.5.0) to `node`, which affects diffImpact scope and explains the ↑41% WASM diffImpact jump (6.4ms → 9ms). fnDeps/fnImpact growth of 6-10% is consistent with codebase expansion across two releases. **Note (3.5.0):** This version has WASM-only data (`native: null`) because the native engine crashed during `insertNodes` in the graph build phase. The root cause is a napi-rs serialization bug: parameter and child nodes with undefined `visibility` fields marshal as `null` at the JS-Rust boundary, which fails conversion into the Rust `Option` type in `InsertNodesDefinition.visibility`. The mid-query target also changed from `noTests` to `db`, which may affect diffImpact scope. Query latencies for 3.5.0 are therefore not directly comparable to prior versions that include both engine rows. This will be fixed in the next release.
