Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When GetUnsafeString addresses a JSON string value, the parser shall return the addressed raw value bytes mapped directly as a Go string without JSON unescaping.
the parser shall always satisfy !addressed_value_is_string | returns_unsafe_string_view

Rationale & tags
Why this requirement exists, and how it is categorised.
GetUnsafeString is explicitly documented as the low-allocation alternative to GetString and needs its own contract coverage.
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).

GetUnsafeString satisfies !addressed_value_is_string | returns_unsafe_string_view: on a successful Get it returns bytesToString(&v), a zero-copy mapping of the addressed raw value bytes directly to a Go string with no Unescape/ParseString call, so JSON escapes are deliberately NOT processed — exactly the unsafe raw view the requirement demands. The property test TestPropertyTypedAccessorsRoundTrip only compares GetUnsafeString against expected values on the no-escape case (strings.ContainsAny gate), matching the no-unescaping semantics, and TestGetUnsafeString provides the example witness.

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.
