+// Hardening assertion semantics generally mirror the evaluation semantics of C++26 Contracts:
+// - `ignore` evaluates the assertion but doesn't do anything if it fails (note that it differs from the Contracts
+// `ignore` semantic which wouldn't evaluate the assertion at all);
+// - `observe` logs an error (indicating, if possible, that the error is fatal) and continues execution;
+// - `quick-enforce` terminates the program as fast as possible (via trapping);
+// - `enforce` logs an error and then terminates the program.
+//
+// Notes:
+// - Continuing execution after a hardening check fails results in undefined behavior; the `observe` semantic is meant
+// to make adopting hardening easier but should not be used outside of this scenario;
+// - C++26 wording for Library Hardening precludes a conforming Hardened implementation from using the Contracts
+// `ignore` semantic when evaluating hardened preconditions in the Library. Libc++ allows using this semantic for
