Definitions
In plain terms
In HMA it is doubled before the full-length WMA is subtracted.
Technical
The implementation must state how n/2 is rounded, validate a positive result, and inherit WMA readiness and missing rules.
Scope
Half-length is derived from n and is not always an exact integer.
Examples
- A governed lesson uses Half-Length WMA only with declared inputs, timing, parameters, and edge-case behavior.
Common misconceptions
- Half-length is derived from n and is not always an exact integer.
