MOS manual section 6.1 defines absolute-indexed address formation. Its memory- modifying note says those operations always spend the additional cycle so the write waits for the correct effective address; an incorrect provisional address may only be read.
Raw traces, ROM material, local paths, and personal data are not part of this public record.
