Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When GetString is called on empty input, the parser shall return the same not-found or error behavior as Get on empty input.
the parser shall always satisfy !getstring_input_is_empty | returns_getstring_error_for_empty_input

Rationale & tags
Why this requirement exists, and how it is categorised.
Empty input to GetString delegates to Get. The empty-input behavior must be explicitly covered.

Browse the catalogueBehavior when inputs are absent, nil, zero-length, or blank.
GetString on an empty []byte returns an empty string without surfacing KeyPathNotFoundError, masking missing data as a valid empty string and corrupting caller presence checks.

Behavior specified when inputs are nil, null, or zero-value.
GetString on nil data panics in nextToken at data[0] instead of returning the not-found result, crashing the caller on a nil trust-boundary input.
