When an Optional Field Comes Back Three Ways: Null, Empty String, and Missing Key in Gemini Structured Output

Optional fields in Gemini structured output drift between null, empty string, and a missing key, and downstream code breaks in three different ways. Here is how I collapse all three into one shape using nullable in responseSchema and a post-output normalization gate, with numbers from a nightly batch.
