Basic vault prototype using OP_CAT

When a code segment involves checking if input.spk matches output.spk, it's essential to pair this validation with an assertion that verifies the index of the input. This approach ensures not only the integrity of data being processed but also safeguards against potential mismatches or errors that could arise when the inputs and outputs are being aligned. This methodology highlights a proactive step in error handling and data verification, underlining the importance of meticulousness in programming practices.
