Case Note: This file was left open after the incomplete attempt by Prof. J. Connor to solve The Strange Case of the Ghost Class. In his last entry, the professor mentioned that this class operated in the shadows, defying all known logic of object-oriented programming. Your mission, should you choose to accept it, is to pick up this investigation where he left off, applying your understanding of the pillars of encapsulation, inheritance, polymorphism, and abstraction. Remember: the code here may seem familiar, but it is full of secrets and abnormalities that will challenge even the strongest knowledge.

In a previous attempt to solve The Strange Case of the Ghost Class, Prof. J. Connor, a renowned expert in object-oriented programming, began an exhaustive investigation to understand the phenomenon of this hidden class. His initial hypothesis suggested that the anomaly was the result of an error in applying the pillars of object-oriented programming, especially in the management of inheritance and encapsulation. He believed that some mishandled instance or a derived class not properly encapsulated could have triggered the unusual effects that students had detected in the system. His curiosity grew steadily with each new step he took.
Convinced that he could solve the mystery, Connor began a difficult review process, analyzing the code line by line and documenting each suspicious interaction. He conducted inheritance tests to verify the relationships between classes, attempted to encapsulate elements he considered problematic, and even rewrote parts of the code in an effort to control the behavior of the ghost class. Nevertheless, it continued to show signs of "having a life of its own," acting unpredictably and resisting any attempt at logical confinement.
As the weeks went by, his notes began to reflect frustration and bewilderment. Connor became so engrossed in the case that he started to question the very foundations of object-oriented programming. After exhausting all conventional debugging tests and techniques, and unable to find a logical explanation to solve the mystery, Prof. J. Connor abandoned the case, unable to pinpoint the source of the anomaly.
In his final report, he left an enigmatic note:
“This class seems to be alive, operating in the shadows and manipulating the system at free will. I have been unable to find a logical explanation within the conventional parameters of object-oriented programming. I am leaving this file open for future investigations; perhaps someone else will succeed in solving what I could not.”
Discover the mystery of the ghost class and understand how the pillars of object-oriented programming (encapsulation, inheritance, polymorphism, and abstraction) can enable or prevent the emergence of a hidden entity in the system. The investigation will focus on discovering whether this anomaly is the result of a perfect implementation of these principles or if it keeps something deeper and more complex.
1️⃣ Identification of fundamental pillars
Identify how each of the pillars of object-oriented programming (encapsulation, inheritance, polymorphism, and abstraction) relates to the behavior and presence of the ghost class in the system.
2️⃣ Analysis of hidden interactions
Examine the interactions of the ghost class with other objects in the system, solving how its presence affects the structure and functioning of the code in unintended ways.
3️⃣ Evaluation of Principles Implementation
Evaluate if the ghost class is the result of an incorrect implementation of the pillars of object-oriented programming, identifying possible design flaws and proposing solutions to prevent such anomalies in the future.
4️⃣ Reflection on best practices
Reflect on the recommended practices in object-oriented programming, highlighting the importance of applying these principles with precision and rigor to avoid unexpected behaviors in complex systems.

The following audio is the last verbal record that Prof. J. Connor left on his personal recorder. I strongly recommend that you listen to it and get your own conclusions.
Prof. Connor left some records of his investigation and code fragments that may contain clues about the behavior of the ghost class. Below are some of his notes and test results. Review them carefully; you might find patterns or inconsistencies that he failed to see.
