Image bounds for the selected pivot word from its prefix sheets
The switch error is proved from the actual Cartan root curves. Only the finitely many outward and return sheet comparisons enter as hypotheses.

OAI.PolycyclicRecognition.CartanWordModel.exists_pivotWordPath_observable_boundline 32Source documentation
Once the profiles on the actual prefixes are close, their entire chosen path has the same height restriction, up to a logarithmic switch error. There is no assumption on profiles at unrelated sheets.
