ProbeLabs23 findings · 123 requirementsWhen GetInt addresses a value that is not a JSON number (e.g., a string, boolean, object, array, or null), the parser shall return a type-mismatch error.
Specification
The requirement exactly as authored — its complete prose text and, where present, the formal FRETish sentence it compiles to.
When GetInt addresses a value that is not a JSON number (e.g., a string, boolean, object, array, or null), the parser shall return a type-mismatch error.
the parser shall always satisfy !getint_addressed_value_is_not_number | returns_getint_type_mismatch_error

Why this requirement exists, and how it is categorised.
Rationale & tags
Why this requirement exists, and how it is categorised.
GetInt has explicit type-checking logic that rejects non-number values. This is behaviorally distinct from successful integer parsing and from malformed-input errors.
Verification & provenance
How this requirement was checked: the review trail, edit history, and the machine-analysis status terms (each ⓘ explains what it means).

GetInt inspects the ValueType from Get and returns a type-mismatch error whenever it is not Number: NullValueError for null and
fmt.Errorf("Value is not a number: %s", ...)for strings, booleans, objects and arrays (parser.go:2100-2104). This satisfies !getint_addressed_value_is_not_number | returns_getint_type_mismatch_error across every non-number type the description lists, and ParseInt (parser.go:2107) is only reached once t == Number. The type guard is independent of the KI-7 overflow defect, which lives solely in the numeric fast path.Cited code (3)

Browse the catalogueGetInt on a string value like "42" silently returns 42 by accepting the wrapped token, masking the type error and corrupting the caller's numeric schema.

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.
