The ladder walks every input upstream of each sampler or guider positive
(not negative, model, clip, latent or image inputs) for PromptManager nodes
whose Save to library is off or wired from an unreadable node, so the
sampler-less step, an off node with a prepend part and a PromptManagerPair
behind a pass-through no longer store its text. The legacy-floor guard reads
a node's resolved text. Every guard reports not_saved for a switch that is
off and not_saved_wired for one it cannot read.
