Summary

Many definitions are missing additionalProperties, and by default JSON Schema assumes additional properties are allowed if additionalProperties is missing. Consequently, mistyped properties are easily missed as validators considers those valid additional properties even if an object actually doesn't allow additional properties.

Basically only need to add "additionalProperties": false to each definition that doesn't permit additional properties.

Use Cases

Better validation, particularly catching mistyped properties early on.
