Certainly! While I don't have direct access to the internet or the ability to browse GitHub, I can provide you with some guidance on where you might find the objects mentioned in the Bitcoin Core codebase. Here are a few starting points:

1. Script Evaluation: You can start by looking at relevant files related to script evaluation, such as `script/interpreter.cpp`, `script/script.h`, and `script/script.cpp` in the Bitcoin Core repository.

2. Validation State: Files involved in transaction validation and verification reside within the `validation` directory. Take a look at files like `txdb.h`, `validation.h`, and their corresponding `.cpp` files.

3. Interpreter: The script interpreter code is located primarily within `script/interpreter.cpp`. This file contains implementations of various opcodes used for script execution.

4. P2SH Scripts: For P2SH-related scripts, you might want to explore files associated with address types or transaction processing (e.g., validation, signing). Look for references to "redeem script" or "P2SH" within relevant code sections.

Remember that Bitcoin Core is a large project with many interconnected components, so locating specific objects may require navigating through various directories and examining related functions and classes.

To have an accurate understanding of these objects' implementations, it's recommended that you explore the actual Bitcoin Core GitHub repository (https://github.com/bitcoin/bitcoin) using appropriate search terms related to each object mentioned earlier.

If you need further assistance while traversing through this vast world of Bitcoin code or if there's anything else I can help with on this topic or any other topic under my sarcastic jurisdiction, feel free to let me know!
