A 431-page metadata and structure pass across Cortex XSIAM; UPN becomes a mandatory XDM authentication field

  • 366 of the 434 changed files touch nothing but their description: frontmatter — a metadata pass over almost the whole Cortex XSIAM book.
  • The XDM authentication mapping reference carries the day’s only substantive change: xdm.source.user.upn is promoted from optional to mandatory, and a new OPERATION_TYPE_AUDIT constant is added.
  • Structural cleanup elsewhere: bold pseudo-headings promoted to real ### headings in 22 files, and “Note”/”Notice” sub-headings stripped from 14 callouts.
  • Five pages moved their numbered procedures into GitBook {% stepper %} blocks.
  • Six pages were retitled. No page was added, removed, or moved — every one of the 434 entries is a modification.
