scan module
A TWASE Scan Module executes against a set of specific attributes pertaining to a given TSN, and on those predefined attributes only, it must return a grading of between 1 and 5; where 1 is probably not twam, thru to 5 being most likely twam.
An individual Scan Module serves a very specific function and thus has a very limited set of TSN data to work with. Scan Modules will sometimes produce false positives or appear incorrect upon reflection due to the nature of diverse dataset processing.
When computing the overall twam score, TWASE considers the grades of all Modules executed within the single scan execution that results in an increased level of accuracy when detecting twam.
