Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When ParseInt receives an empty byte slice, the parser shall return MalformedValueError because an empty token is not a valid integer representation.
the parser shall always satisfy !parseint_input_is_empty | returns_parseint_malformed_for_empty

Rationale & tags
Why this requirement exists, and how it is categorised.
Empty input to ParseInt is a distinct boundary case from malformed non-empty tokens and overflow tokens.

ParseInt on a zero-length token returns 0 (silent success) instead of MalformedValueError, masking missing data as a valid zero and corrupting downstream accumulator invariants.
