v3.1.1

Reliability, architecture, and MCP cold-start fixes. This patch breaks a circular dependency cycle, fixes MCP server first-connect reliability by deferring heavy imports, corrects flow matching to use core symbol kinds, and refactors all database access to use try/finally for reliable db.close(). Internal architecture improves with repository pattern for data access and command/query separation.

Features

• hooks: add pre-commit hooks for cycles, dead exports, signature warnings (#381)
• benchmark: add 1-file rebuild phase breakdown to build benchmarks (#370)

Bug Fixes

• cycles: break circular dependency cycle and remove dead queryName export (#378)
• queries: use CORE_SYMBOL_KINDS in flow matching (#382)
• mcp: defer heavy imports in MCP server for first-connect reliability (#380)

Refactors

• wrap all db usage in try/finally for reliable db.close() (#384, #383)
• repository pattern for data access (#371)
• command/query separation — extract CLI wrappers, shared output helper (#373)

Chores

• ci: allow merge type in commitlint config (#385)
• deps-dev: bump tree-sitter-go from 0.23.4 to 0.25.0 (#356)

v3.1.0

Sequence diagrams, native engine performance leap, and unused export detection. This release adds codegraph sequence for Mermaid sequence diagram generation from call graph edges, delivers major native engine build optimizations (deep-clone elimination, batched SQLite inserts, call edge building in Rust, FS caching, rayon-parallel import resolution), introduces --unused on the exports command to detect dead exports, and fixes an ~80x native no-op rebuild regression.

Features

• sequence: add codegraph sequence <name> command for Mermaid sequence diagram generation from call graph edges — participants are files, BFS forward from entry point, optional --dataflow flag for parameter/return annotations; exposed via CLI, MCP tool, and programmatic API (#345)
• exports: add --unused flag to codegraph exports — new exported column (migration v14) populated from parser export declarations, enabling detection of symbols declared as exports but with zero consumers (#361)

Performance

• native: eliminate deep-clone in normalizeNativeSymbols — replace 125-line JS deep-clone with in-place patchNativeResult via #[napi(js_name)] annotations on Rust types (#361)
• native: add include_ast_nodes flag to parse_file/parse_files — initial parse skips AST node walking, saving ~200ms (#361)
• native: move call/receiver/extends edge building to Rust (edge_builder.rs) — narrowest-span caller resolution, confidence sorting, dedup via u64 edge keys (#361)
• native: add known_files HashSet cache to resolve_imports_batch — avoids redundant FS syscalls during import resolution (#361)
• native: parallelize resolve_imports_batch with rayon for concurrent import resolution (#361)
• builder: batch SQLite multi-value INSERTs — accumulate node/edge rows and flush with chunked INSERT statements (200 rows per chunk) instead of individual prepared statement runs (#361)

Bug Fixes

• native: fix no-op rebuild regression (~80x slower than WASM) — extToLang map was not built when native engine provided pre-computed CFG, causing langId lookup to return null and triggering full re-parse on every incremental build (#360)
• native: pass full file list to known_files cache — on incremental builds only changed files were passed, causing valid import targets to be dropped (#361)
• benchmark: install native package explicitly in npm benchmark mode (#351)

Documentation

• reorder README to be AI-first throughout (#362)
• add MCP tool surface optimization proposal (#363)
• update build performance, query, and incremental benchmarks for 3.0.4 (#352, #353, #354)

Chores

• deps: bump graphology from 0.25.4 to 0.26.0 (#358)
• deps-dev: bump @biomejs/biome from 2.4.4 to 2.4.6 (#359)
• deps-dev: bump @commitlint/cli from 20.4.2 to 20.4.3 (#357)
• deps-dev: bump @commitlint/config-conventional (#355)

v3.0.4 Performance

Native engine goes full-stack: CFG, AST nodes, and WASM double-parse elimination. This release completes the native engine migration — CFG computation and AST node extraction now run in Rust for 8 languages, eliminating the redundant WASM pre-parse on native builds.

Performance

• native: compute CFG in Rust native engine for all 8 languages (JS/TS/TSX, Python, Go, Rust, Java, C#, Ruby, PHP) — ports buildFunctionCFG algorithm to Rust with per-language CfgRules, eliminates WASM re-parsing in CFG phase (#342)
• native: extract AST nodes (call, new, throw, await, string, regex) for all non-JS languages in Rust via shared walk_ast_nodes_with_config() — astMs drops from ~651ms to ~50ms (#340)
• builder: skip ensureWasmTrees entirely when native engine provides complete CFG + dataflow + AST data — wasmPreMs drops from ~388ms to 0 on native builds (#344)

Bug Fixes

• native: fix function-scoped const declarations being incorrectly extracted as top-level constants (#344)
• benchmark: show all build phases (astMs, cfgMs, dataflowMs, wasmPreMs) in benchmark report and document v3.0.0→v3.0.3 native regression cause (#339)

3.0.3 (2026-03-04)

Note: 3.0.2 was an internal/unpublished version used during development.

v3.0.3 Performance

Performance

• ast: use single transaction for AST node insertion — astMs drops from ~3600ms to ~350ms (native) and ~547ms (WASM), reducing overall native build from 24.9 to 8.5 ms/file (#333)

v3.0.2 Patch

Dataflow goes multi-language, build performance recovery, and native engine parity fixes. This patch extends dataflow analysis from JS/TS-only to all 11 supported languages, recovers build performance lost after CFG/dataflow became default-on, fixes language-aware identifier collection in dataflow, and closes a native engine scoping bug for constants.

Features

• dataflow: extend dataflow analysis to all supported languages (Python, Go, Rust, Java, C#, PHP, Ruby) with per-language DATAFLOW_RULES and makeDataflowRules() factory (#318)

Bug Fixes

• dataflow: use isIdent in collectIdentifiers for language-aware referencedNames — fixes PHP variable_name and other non-identifier node types being missed in return statements (#324)
• native: skip local constants inside function bodies — the native JS extractor incorrectly extracted function-scoped const as top-level constants (#327)
• native: enable extended kinds (parameters, properties, constants, receivers) in parity tests and update native binary to v3.0.1 (#327)

Performance

• builder: fix v3.0.1 build performance regression (14.1 → ~5.8 ms/file) — eliminate redundant WASM parsing via ensureWasmTrees(), memoize createParsers(), filter CFG/dataflow to changed files only (#325)

Documentation

• update build performance, query, and incremental benchmarks for 3.0.1 (#321, #322, #323)
