Python CI/CD (unix, microsoft) now skips runs when only Rust-port files change (crates/, Cargo manifests, docs/, Justfile). New rust.yml runs fmt + clippy -D warnings + the full test suite (including golden parity) on Linux/macOS/Windows with autocrlf disabled so byte-level goldens hold.

generate_legacy_goldens.py captures the Python implementation's outputs: per-fixture components, token/line counts, full tree renders, and v1-scope tree renders (deferred-language extractors stubbed). These are the behavioral contract for the Rust port's parity suite. diff_components.py is the dev-loop diff tool. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
tree_plus_core: model, deterministic rich-compatible renderer, natural sort (natsort os_sorted parity), fnmatch-compatible ignores, amortized globs, wc-parity counting, and component extraction: - tree-sitter extractors for Rust, Python, JS/TS, C/C++ with formatters that reproduce the legacy output (golden-parity tested, including catastrophic.c) and salvage ERROR regions on invalid syntax - regex extractors (LazyLock, linear-time engine only) for markers, Markdown/RST/txt, .env, requirements, Makefile/Justfile, Angular - native parsers for JSON/JSONL/YAML/TOML/CSV and SQLite (feature) tree_plus_cli: clap binary as tree_plus + tprs alias (PATH collision with the Python entry point), legacy flags, footer parity, real terminal-width detection. Parallel traversal with rayon behind a deterministic sort; arbitrary bytes never panic (robustness suite); criterion benches included. 55-85x faster than the Python implementation end to end.

type struct/interface headers and column-0 func signatures, matching
legacy parse_go exactly (golden-parity tested, including the multiline
method signature fixture). Legacy quirks preserved: `func f() {}` and
generic type headers are skipped, raw tabs kept in signatures.

Two distinct overflows surfaced by running tprs on the Linux kernel: 1. Tree-sitter extractor visitors (C/C++, Rust, Python, TypeScript, Go) recursed on AST depth. arch/x86/kernel/cpu/microcode/intel-ucode-defs.h is a headerless initializer-list fragment that parses as a deeply nested ERROR tree and blew rayon's 2 MiB worker stacks. All visitors now traverse with explicit heap stacks; emission order is unchanged (golden parity suite still passes byte-for-byte). The C/C++ extractor threads deferred work (record closers, template field suppression, ERROR salvage) through a Work queue to preserve legacy ordering. 2. Rayon work-stealing nests from_folder frames on a worker while it waits in join, leaving too little headroom for tree-sitter's C frames on big trees (drivers/ segfaulted in ts_subtree_retain). from_seeds now runs in a dedicated pool with 16 MiB worker stacks. Adds a regression test extracting deeply nested inputs for all six tree-sitter languages on a 512 KiB thread, and records Linux-kernel benchmarks in docs/performance.md (101k files: concise 0.50 s, full 12.4 s; linux/kernel subdir ~56x faster than the Python CLI).

What
Rust rewrite of tree_plus for the declared version-1 scope (local filesystem mode), preserving the Python implementation's observable behavior via golden parity tests.
