Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When GetUnsafeString 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 !getunsafestring_input_is_empty | returns_getunsafestring_error_for_empty

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

Empty-input behavior mirrors Get by construction: GetUnsafeString (parser.go:2032) forwards Get's error unchanged, and Get on with a key returns KeyPathNotFoundError from searchKeysConfig's -1 result (internalGetConfig, parser.go:1672). TestGetUnsafeStringEmptyInput and MCDC rows 2/3 confirm err!=nil on empty input, while row1 shows no error on
{"a":"b"}. No panic path exists because the empty slice never gets indexed before the searchKeys guard fires.Cited code (3)

Browse the catalogueBehavior when inputs are absent, nil, zero-length, or blank.
GetUnsafeString on an empty []byte returns a non-empty string from a stale buffer instead of the not-found result, leaking stale memory to the caller.

Behavior specified when inputs are nil, null, or zero-value.
GetUnsafeString 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.

MC/DC truth table· 3 rows
Each row assigns the formula's conditions (T/F) and shows the Result— the formula's value for that input row, not a test pass/fail. A row proves a condition when flipping only that condition flips the outcome. The test that covers each row is linked.
