Read a waiting plan's advice.

A waiting plan's advice is never a gate: the plan stays approvable either way. openingNovelty says when its opening echoes an earlier film of the same product and the one change that avoids it (alternative.field and alternative.value); signatureDeviceAgreement says which capture beats show a different device from the one the story's cast is always seen with (mismatchedBeatIds). Applying one changes only the beat it names and nothing else. Free. The same advice the plan review card shows. Both fields are null on a plan that no longer waits for approval, or has nothing to advise.
