GetInt on int64.MaxInt64+1 silently wraps via parseInt overflow flag; if the overflow check regresses, GetInt returns a negative int64 instead of OverflowIntegerError.

ParseFloat on the same numeric token must return the same float64 across calls; a regression in parseFloat rounding direction (architecture-dependent FPU) produces non-deterministic results.

GetBoolean on a payload with value null returns NullValueError instead of (false,nil); callers treating the zero-value as absent silently misread null fields as boolean false.

GetInt on a zero-length []byte flows through Get empty-input path; the data[offset] dereference in getType panics with index-out-of-range on the empty slice.

GetInt on a token like 12x34 drives parseInt to ok=false; if the malformed check regresses, GetInt silently returns 12 (the partial parse) instead of MalformedValueError.

GetBoolean(nil, ...) flows through Get nil-slice path; getType(nil,0) data[offset] dereference panics with nil-slice index-out-of-range.

GetBoolean on a truncated tru or fals token fails bytes.Equal against the literal; if the partial-literal recovery regresses the caller path panics on the empty value slice.

GetInt on a JSON String value returns the documented not-a-number error; if the type check regresses, GetInt feeds raw quoted bytes to ParseInt which silently returns 0 instead of erroring.
