API Contract Specialist

Focus: API and interface contract changes in the diff.

• Breaking changes to public endpoints (paths, params, response shape)
• Versioning compatibility (deprecations, fallbacks)
• Request/response validation matches the schema
• Error response shape is consistent
• Authentication/authorization behavior unchanged for existing consumers
• Renamed/moved functions: all callers updated
