 ### Bug Fixes
 
 * **ruby:** use `rails test` instead of `rake test` when positional file args are passed — `rake test` ignores positional files and only supports `TEST=path`
+* **cargo:** preserve compile diagnostics when `cargo test` fails before any test suites run
 
 ### Features
 
+* **gradle**: add Gradle command support with sub-enum routing (test/build/other) — 75-90% token savings
+* **maven**: add Maven command support with Surefire test parser (test/compile/package/other) — 70-90% token savings
+* **gradle**: auto-detect ./gradlew wrapper with fallback to gradle on PATH
+* **maven**: intelligent Surefire output parsing — failures only with compact error messages
+* **discover**: add Gradle/Maven rewrite rules for transparent hook integration
 * **ruby:** add RSpec test runner filter with JSON parsing and text fallback (60%+ reduction)
 * **ruby:** add RuboCop linter filter with JSON parsing, grouped by cop/severity (60%+ reduction)
 * **ruby:** add Minitest filter for `rake test` / `rails test` with state machine parser (85-90% reduction)
 * **ruby:** add TOML filter for `bundle install/update` — strip `Using` lines (90%+ reduction)
 * **ruby:** add `ruby_exec()` shared utility for auto-detecting `bundle exec` when Gemfile exists
 * **ruby:** add discover/rewrite rules for rake, rails, rspec, rubocop, and bundle commands
