Unit 13 Boundary Trace
Take one dashboard run and label the evidence by layer:
REQUEST
HTTP RESULT
BODY / JSON
LOCAL DATA STRUCTURE
ANALYSIS RESULT
If the live request failed, that is valid evidence. Identify where it failed and which later layers never executed.
Then compare that run with the local fixture path. Explain which part of the program remained identical and why separating acquisition from analysis made that possible.
Finish by naming one payload change your code would currently reject, mishandle, or silently misunderstand.
