Note (3.9.2): The diffImpact latency regressed significantly — WASM jumped from 6.5ms to 12.6ms (↑94%) and native from 7.5ms to 9.6ms (↑28%), reversing the improvements seen in 3.9.1. This is tracked in #904 for investigation in the query/resolution path. The mid-connectivity target also changed from ctx (3.9.1) to node (3.9.2); targets are selected dynamically at run time as the most-connected nodes of their tier, so this shift reflects genuine changes in graph connectivity structure as the codebase evolves. fnDeps growth of 5-15% and fnImpact growth of 10-15% are consistent with normal codebase expansion.
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<String> 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.
Note (3.4.1): The ↑45% diffImpact delta is inflated by 3.4.0 being an unusually low baseline (5.6ms/4.9ms). The new absolute values (8.1ms native, 7.1ms wasm) fall within the historical range (e.g. 3.1.3: 8.3ms, 3.3.0: 8.8ms). The mid-query target also changed from rule to noTests, which may affect diffImpact scope. No engine regression — fnDeps grew only 5-7% (consistent with codebase expansion) and fnImpact is flat-to-slightly-down.
Note (3.4.0): The ↑136-143% fnDeps deltas for 3.4.0 vs 3.3.1 reflect codebase growth — buildGraph has significantly more edges in this release (new extractors, refactored domain/features layers). The mid-query target also changed from db to rule. There is no engine regression — native diffImpact improved 20% in the same release.
Note (3.3.1): The ↑157-192% fnDeps/fnImpact deltas for 3.3.1 vs 3.3.0 are not comparable. PR #528 changed the hub target from auto-selected src/types.ts (shallow type-barrel) to pinned buildGraph (deep orchestration function with 2-3x more edges). There is no engine regression — diffImpact improved 20-44% in the same release. Future version comparisons (3.3.1+) are stable and meaningful.
