A simple Owasm script with the following specification:

PREPARE:

A silly oracle script, primarily to test that you must make at least one raw request:

PREPARE:
  DO NOTHING
EXECUTE:
  DO NOTHING

var Wasm4 []byte

An oracle script for testing complex interactions.

PREPARE:
  Call into the given data source ids with the given calldata.
EXECUTE:
  Assume all validators report, append all reports to the final result.
