A one-time pad is unbreakable, provided it is true, and that second half, the quiet condition, is where the whole claim lives. A true pad is a very specific object: genuinely random, at least as long as the message, used once, kept secret, never copied, logged, inferred, generated from a seed, or reused by accident. The word “true” is doing all the work. This piece pulls that condition into the light, showing how a guarantee that is flawless in theory turns fragile the moment it meets real machines and real people. The proof is easy; the discipline is not. And the lesson generalises far beyond cryptography: a word carries a claim only when the thing it names actually satisfies the conditions that make the claim hold. Until then it is language with ambitions.
