Can you cite a statute that requires a provider to look for hashes when NCMEC asks them to? If NCMEC told a provider that a specific URL (or similarly unique identifier) contains CSAM, the provider would be obligated to destroy the associated file or be guilty of possession/distribution because at that point they know what they have. That's different from NCMEC providing hashes that could identify files the provider may or may not be storing.
