Layering

Keeping non-essential detail available without placing it in the reader's path, by moving it below the essential content, into an appendix, a footnote, an "on request" line, or a linked document; the document-level application of progressive disclosure and the safe alternative to deleting content the reader might need.

The practice of moving money through multiple accounts, people, and payment rails in quick succession specifically to make its criminal origin harder to trace by the time an investigator reaches the far end of the chain; a mule's account is typically one layer in this process, not the final destination.

The process of moving funds through a series of further transfers to obscure their origin, discussed in Section 3Y8 as the step between a victim's deposit and the funds' eventual, more permanent destination.
