 ### Compatibility
 
-Compatible with MRI Ruby {KJ|MIN_RUBY}+, and concordant releases of JRuby, and TruffleRuby.
+The gem's declared runtime compatibility floor is MRI Ruby {KJ|MIN_RUBY}+, with concordant releases of JRuby and TruffleRuby.
 CI workflows and Appraisals are generated for MRI Ruby {KJ|MIN_TEST_RUBY}+.
 The current MRI CI lane runs on {KJ|README:CURRENT_MRI_PLATFORMS}.
-This test floor is configured by `ruby.test_minimum` in `.kettle-jem.yml` and
-may be higher than the gem's runtime compatibility floor when legacy Rubies are
-not practical for the current toolchain.
+The test floor is configured by `ruby.test_minimum` in `.kettle-jem.yml`.
+When it is higher than the runtime floor, older runtime-compatible Rubies are
+not covered by the generated CI or Appraisal matrix.
