Precommit, give him the Galleon, then reach in her bag to get the 100 Galleons. (She must have been Obliviated; otherwise, she would remember.)
You can never know consistency, can never rely on it, otherwise you are inconsistent (2nd incompleteness theorem).
Though Godel was interested in time travel loops, that’s not the type of consistency that his Second Incompleteness Theorem discussed (it’s limited to formal axiomatized systems that can describe arithmetic).
I suspect Vladmir is considering the system in question here in a way that meets that description.
