What could be the consequence of not being able to decode the notes?

The consequence of not being able to decode the notes primarily leads to a loss of important information. When notes are encoded or written in a way that is not easily understood, the essential details, instructions, or insights they contain become inaccessible to the individual trying to interpret them. This inability to decode means that critical points may be missed, decisions may be based on incomplete understanding, and overall effectiveness can be significantly diminished.

Improvement in knowledge, clarity of the encoded message, and the ability to retrieve other information generally presuppose successful decoding. If decoding is not achieved, these positive outcomes cannot occur, and therefore the most direct and negative consequence is indeed the loss of valuable information contained within the notes.
