Commonly assumed
T::Struct.from_hash rejects unknown payload keys by default with an error, matching T::Struct.new constructor validation.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- assert from_hash with unset strict argument permits unknown hash keys and retains them in serialize, whereas T::Struct.new raises ArgumentError
- assert from_hash! and from_hash with strict: true raise RuntimeError when unknown keys are provided
- assert from_hash requires string keys and fails on symbol keys because keys are looked up without symbol conversion
- assert serialize defaults to strict: true, validating required properties unless explicitly relaxed
