  Highlights

  Ruby is now a fully supported language (sixth indexed language), with Rails-aware extraction — and this release closes a stack-overflow DoS that affected every language parser.

  Ruby plugin

  • Detects .rb / .rake / .gemspec and the extensionless Rakefile / Gemfile.
  • Modules, classes (+ superclass type refs), instance & singleton methods, top-level functions, constants, attr_* fields, require/require_relative imports, bare-call vs receiver method_call refs, and include/extend/prepend mixin refs.
  • Rails-aware associations: has_many / has_one / belongs_to / has_and_belongs_to_many emit a type reference to the associated model class — honoring class_name: and singularizing plural names — so find_references on a model surfaces its association sites.

  Security: parser recursion-depth guard

  A crafted file of deeply nested literals (well under the 2 MiB size cap) could overflow the worker stack and crash the long-lived daemon — and catch_unwind cannot intercept stack exhaustion. All six language plugins now cap recursion depth, so a single malicious file can no longer take down the daemon. Verified with a 2 MiB-stack regression test on 20 000-deep input.

  Parity & tests

  Wired Ruby into qualified-name separators, project-root detection (Gemfile/*.gemspec), entry-point heuristics, ctags cross-validation, and the init template. Ships 25 unit tests, full e2e + Rails-association + parity coverage, and a 5-layer correctness_ruby cross-validation against ripgrep/ctags.

  Reviewed ultradeep by a multi-agent pass (correctness, security, performance, test coverage, cross-language parity, production readiness) with adversarial verification of every finding.
