adviceFor
private fun adviceFor(phase: Patch.Phase, slot: Int, key: String, matcher: ElementMatcher<MethodDescription>, rt: TypeDescription?): AsmVisitorWrapper?
The visitor for phase, or null when there is nothing left to weave.
AROUND is a composition, not a blueprint of its own: the observe advice goes INSIDE the intercept, so the short-circuit jump clears it along with the body — skipOn cannot skip an exit advice of its own advice, but it does skip a nested one. Order is load-bearing and verified against the woven bytecode: AsmVisitorWrapper.Compound's FIRST element ends up outermost, the last hugging the original body.
