Independent pre-consent evidence, not self-reporting
Cookie Script's scanner runs inside the same vendor that also serves your banner, so its declaration describes what the CMP intends to control. CookieSentry visits your live page as an outside observer and records what actually fires before any consent click, naming each cookie and its source. When a regulator or client asks for proof, evidence from a tool that does not also sell you the banner carries weight a self-issued declaration cannot.
