 - Restored Ruby 2.3 Caboose CI bundle resolution by using the last compatible kettle development/test toolchain on that EOL runtime.
 - Kept Ruby 2.3 Caboose CI on the last compatible `gitmoji-regex` release.
 - Added the missing Ruby 2.3 modular stdlib gemfiles required by generated Caboose appraisals.
+- Ran Ruby 2.3 Caboose specs directly with `rspec` because the compatible `kettle-test` 1.x toolchain does not expose the newer executable.
 - Replaced stale platform CI `rake magic` commands with portable spec commands.
 - Pinned `multi_xml` below 0.9 for TruffleRuby compatibility.
 - Marked EOL TruffleRuby 22.3, 23.0, and 23.1 CI as experimental because they can crash inside the interpreter during Bundler setup.
