Choose, author, and validate tests for the AIHC repository. Use when Codex needs to add or update tests in components/aihc-cpp, components/aihc-parser, components/aihc-resolve, components/aihc-tc, components/aihc-fc, components/aihc-grin, or related compatibility/property suites, including unit tests, golden YAML fixtures, oracle fixtures, lexer fixtures, error-message fixtures, eval fixtures, and QuickCheck properties.

Debug `aihc-parser` parse, pretty-printer, paren-insertion, and QuickCheck round-trip failures using `aihc-dev snippet` to distinguish invalid generated code from parser regressions.
