Equivalence Reasoning

stylistic

The agent patch implements the core behavioral intent: for `openapi-3.0`, `null` is emitted using OpenAPI-compatible nullable schema (`type: "string"`, `nullable: true`, `enum: [null]`), unions now preserve `anyOf` members (including null schema) instead of collapsing, and tuple/null output matches expected nullable semantics. It also updates tests for union/null/tuple cases; extra literal-null handling is additive and aligned with the same intent.

Code Review

correctness: 3/4introduced bug risk: 3/4edge case handling: 3/4maintainability idioms: 3/4

The agent patch likely satisfies the intended OpenAPI 3.0 null-handling change for tuples/unions and appears behaviorally aligned with the task, with moderate confidence and no material blocking issues identified.
