  "summary": "Static review of kotlinx.serialization wire-contract safety and schema evolution: encodeDefaults/explicitNulls defaults, @EncodeDefault overrides, strict-decode unknown-key rejection, sealed-class closed polymorphism and class discriminators, and breaking-change detection for optional/required-field evolution. Reads source and serializer configuration only.",

  "security_notes": "Static review only — reads Kotlin `@Serializable` classes, `Json {}` configuration, and sanitized sample payloads; never builds, runs, or sends/receives real wire traffic, and never handles production payloads or customer data. A claim about actual producer/consumer version skew in a live system is flagged as needing verification rather than asserted. Never requests secrets, credentials, or customer data.",
