v0.9.66

• Feature: five new language extractors — COBOL (.cbl/.cob/.cobol/.cpy; programs, paragraphs, PERFORM/CALL/COPY, pure-regex, no new dependency) (#3713, thanks @Abdul535), VB.NET (.vb; case-insensitive types/methods, Inherits/Implements/Handles) (#3717, thanks @Abdul535), R (.r/.R; assignment-form function defs, library/source, S4/R6 classes) (#3715, thanks @Abdul535), Solidity (.sol; contracts/interfaces/libraries, is inheritance, imports, modifiers) (#3716, thanks @Abdul535), and Erlang (.erl/.hrl/.escript; modules, functions by arity, behaviours, local + remote foo:bar() calls) (#3714, thanks @Abdul535). The R and Erlang grammars ship via the r/erlang extras (they have no standalone PyPI wheel); Solidity and VB.NET have their own extras.
• Feature: Go interface method requirements now resolve to the interface, and their parameter/return types emit references edges (#3672, #3737, thanks @rajatnagda45, @oleksii-tumanov).
• Feature: a Rust self.method() call resolves across files for simple generic impls (impl<T> Foo<T>) (#3653, thanks @oleksii-tumanov).
• Fix: graph.json is now deterministic across runs — update/extract/cluster-only/label pin PYTHONHASHSEED via a one-time re-exec, so hash-seed-sensitive community detection (Leiden/Louvain) produces identical output run-to-run and matches hook-triggered rebuilds (#3743, #3641, thanks @ayushcodes10).
• Fix: a same-relation edge collision now keeps the higher-confidence edge (EXTRACTED over INFERRED) instead of resolving by arrival order (#3711, thanks @shobhitagnihotri69).
• Fix: a spec-conformant method-node duplicate (dropped class segment / leading dot) is now deduplicated onto its canonical AST node, gated on a method-shaped label and a single unambiguous candidate (#3719, #3705, thanks @shobhitagnihotri69).
• Fix: intra-module Go imports_from edges now repoint onto the imported package's real file nodes instead of dangling at a go_pkg_ sink; external/stdlib imports stay external (#3748, thanks @carterko23).
• Fix: Cargo introspection discovers a Cargo.toml in a subdirectory when none sits at the scan root (e.g. Tauri's src-tauri/), degrades gracefully instead of aborting the whole extraction when no manifest is found, and resolves workspace = true inherited dependency identity from [workspace.dependencies] (#3740, #3739, thanks @ayushcodes10; #3734, thanks @oleksii-tumanov).
• Fix: MCP get_node/get_neighbors now accept the node identifier under node_id/id, not only label, so agents that spell the argument differently no longer get a missing-argument error (#3725, thanks @ahm3dwasim).
• Fix: graphify install no longer corrupts line endings (writes preserve the file's existing EOLs instead of rewriting to CRLF on Windows) and re-install is properly idempotent (a marker-bounded replace instead of a bare substring check) (#3741, #3668, thanks @ayushcodes10).
• Fix: community labeling retries a valid-but-truncated LLM response and reports how many communities kept a structural fallback name, instead of silently leaving them unlabeled (#3708, thanks @Ha1baraA11).
• Fix: a stale .graphify_root marker (moved/deleted/symlink-loop target) is now ignored with a fall-back to the graph's directory, and the marker value resolves to an absolute path when GRAPHIFY_OUT is a shared absolute directory (#3707, thanks @Ha1baraA11; #3735, #3375, thanks @ayushcodes10).
