TITAN-DIV-32	Divergence	Code ships a bare, one-override `AppBar`; the design library’s page template depicts a composed site header with a logo, account selector, global search, and account menu

No composed “site header” export exists. AppBar, Logo, and Menu exist independently; nothing wires them together, and no global-search export exists at all. See the main page’s Composition section for the full inventory.
AppBar’s stacking order relative to the page frame’s sticky Header is unconfirmed. Header uses the z-sticky token; AppBar has no equivalent override recorded anywhere in the theme. Whether the two coordinate correctly when both are sticky on one page was not tested.
Whether any of the eight applications using bare AppBar actually match the design library’s intended composition was not checked. utilization.md records the usages; it says nothing about what each application built around them.
No accessible-name or landmark guidance exists for a composed site header, since no such component exists to check. AppBar’s own default <header> landmark is confirmed; anything beyond that is unverified.
