What is verified—and what is not
Verified: official notice status and deadline, exact first-tier language, exact certification language, attachment, page, and location. Not represented: that a specific prime has an open subcontract, that the TAB scope has a known dollar value, or that any firm will receive work. Those items require direct prime confirmation.
