The SEC filing clause (4.6(a)) is probably more germane than the proxy materials when it comes to bot calculations, and page 5 of the last Twitter 10-K covers their methodology. One can argue with their calculation method, but they're clear about how they're doing it and, as long as nothing comes to light documenting that they internally believe their bot rates to be higher than what their filing shows, they're in material compliance with the contract. There's no due-dil out for Musk in this, only a material misrepresentation penalty that Twitter is highly, highly unlikely to fall afoul of.
