Contract

• assert JSON.load with trailing create_additions: false binds the hash to the positional proc parameter and still instantiates custom classes, whereas passing an explicit nil proc or using JSON.parse safely returns a Hash
• assert JSON.parse rejects nesting depth exceeding 100 with JSON::NestingError, but max_nesting: 0, false, and nil all disable depth enforcement completely rather than forbidding nesting
• assert JSON.parse with freeze: true deeply freezes all containers, nested arrays, strings, and symbolized keys, raising FrozenError on in-place mutation at any depth
• assert JSON.generate leaves </script> unescaped by default, while script_safe: true escapes </ to <\/ without altering round-trip parsed data and ascii_only: true encodes non-ASCII into unicode escapes
• assert custom container classes passed via object_class receive Symbol keys directly when symbolize_names: true is enabled
