+# Globally Disabled checks:
+#
+# bugprone-easily-swappable-parameters: This warning is loud with no clear advice on how to fix the potential problem
+# FIXME: bugprone-macro-parentheses: Enable with clang-tidy-14 when NOLINTBEGIN/NOLINTEND are available for code generating macros
+# bugprone-reserved-identifier: LibC headers that show up in the header filter are part of "the implementation"
+#   cert-dcl37-c: Alias for bugprone-reserved-identifier
+#   cert-dcl51-cpp: Alias for bugprone-reserved-identifier
+# cert-dcl21-cpp: No reference to this rule exists on Carnegie Mellon's SEI CERT C++ Confluence. And the suggestion is unusual
+# FIXME: misc-non-private-member-variables-in-classes: Audit uses of protected member variables to see if they really need to be protected
+# performance-noexcept-move-constructor: The project does not use exceptions, so there are no such optimizations available
+# performance-no-int-to-ptr: This rule flags every pointer to integer cast, which gets quite noisy. Should only be enabled on a case-by-case basis
+# readability-braces-around-statements: Redundant braces around single-line conditions is against project style
+# readability-magic-numbers: This check is very noisy in the codebase, especially in AK.
+# readability-named-parameter: We frequently omit parameter names to work around -Wunused-parameter
+# FIXME: readability-uppercase-literal-suffix: Enable this check, the rationale is solid but the findings are numerous
