The plaintext condition
Also called Plaintext requirement, The privacy fork.
Server-side intelligence requires readable content, so any capability that runs on a server is itself a statement that the server can read what it runs on. Embedding, ranking, indexing, and reasoning all consume the text before they produce anything, and encrypted values cannot be matched, measured, or indexed by a party holding no key. The consequence is that end-to-end encryption and server-side processing are mutually exclusive rather than tunable against each other, which makes a private mode a second product rather than a setting inside one, and makes an interface that presents the choice as a checkbox a claim about size that is not true.
