Add a libfyaml? helper and guard the tests that intentionally diverge on the experimental YAML 1.2 backend: yes/no/on/off are strings rather than booleans, flow collections and block scalars are formatted differently, tags and marks are reported differently, and non-ASCII tags/aliases are rejected. test_boolean asserts the 1.2 string result directly; the formatting and mark cases are skipped. The default libyaml build is unaffected (every guard keys off Psych::BACKEND). https://github.com/ruby/psych/commit/67b6365f5a Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
