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 malformed input where the underlying Get call returns an error, GetUnsafeString shall propagate that error to the caller.
the parser shall always satisfy !getunsafestring_input_is_malformed | returns_getunsafestring_error_for_malformed

Rationale & tags
Why this requirement exists, and how it is categorised.
GetUnsafeString delegates to Get for path resolution. Malformed input errors from Get must be propagated.

GetUnsafeString (parser.go:2032) is a thin delegate that returns "",e whenever the underlying Get call errors, so malformed input error propagation is structurally guaranteed. On
{"a"::Get -> internalGetConfig classifies the value after the colon and fails (getTypeConfig / nextToken path), and TestGetUnsafeStringMalformedInput asserts err!=nil for exactly this input. MCDC row1 confirms no spurious error on well-formed{"a":"b"}. The error-propagation clause is grounded directly in the e!=nil guard.Cited code (3)

What this requirement must witness to be considered satisfied — the required evidence, and the tests that discharge each one.

Browse the catalogueBehavior when inputs are syntactically or structurally invalid.
GetUnsafeString on adversarial input where Get returns an error discards the error and returns a stale raw slice past EOF; the caller reads out-of-range bytes and panics in the unescape path.

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.
