When GetUnsafeString is called on JSON containing values with Unicode edge cases (BOM, ZWJ, multi-byte sequences), the parser shall return the raw bytes as a Go string without corruption or panic, even though unescaping is skipped.

Specification

The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.

Description

When GetUnsafeString is called on JSON containing values with Unicode edge cases (BOM, ZWJ, multi-byte sequences), the parser shall return the raw bytes as a Go string without corruption or panic, even though unescaping is skipped.

FRETish formula
the parser shall always satisfy !getunsafestring_input_has_unicode_edge_cases | getunsafestring_handles_unicode_edges_safely

Rationale & tags

Why this requirement exists, and how it is categorised.

GetUnsafeString returns raw bytes as a Go string. Multi-byte sequences at value boundaries must not cause slice-out-of-bounds panics.

Obligations

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

No obligations recorded for this requirement

Proof obligations are recorded once evidence is generated. None have been captured here yet — this is expected, not a gap in the requirement itself. A required class of evidence the requirement must witness — the bridge between the requirement existing and it being proven.

Formula evidence

The formal formula behind this requirement, the variables it is written over, and the tests that exercise it (each term is explained inline).

FRETish formula

the parser shall always satisfy !getunsafestring_input_has_unicode_edge_cases | getunsafestring_handles_unicode_edges_safely

Variables

NameTypeDirectionDescription
getunsafestring_input_has_unicode_edge_casesTrue when GetUnsafeString addresses a value with Unicode edge cases.
getunsafestring_handles_unicode_edges_safelyTrue when GetUnsafeString returns raw bytes as Go string without corruption for Unicode edge cases.
