paper: replace two defensive 'X not Y' framings with positive statements

Longrun caption: drop 'Pre-empts the "you stopped at 60 steps" critique: durable
not delayed' (answers an offstage referee objection) -> state the positive (gap
opens by step 60, persists to 200). Alignment bullet: apply the user's own flagged
humanizer note -- drop the agent-added 'not an enumeration ... nor a monitor'
X-not-Y-nor-Z clause, state 'needs only the hack subspace', remove the resolved note.

 \section{Why this matters for alignment}
 % User-dictated points kept verbatim; agent-suggested extras flagged below.
 \begin{itemize}
-  % humanizer: [#9 negative framing] the "not an enumeration ... nor a monitor"
-  % clause is an AI tell (X-not-Y-nor-Z) and is agent-added, not your dictation.
-  % Suggest stating the positive directly, e.g. "it needs only the hack's
-  % subspace" and dropping the contrast, or cut to your original line.
   \item Intervening on the model's internal representation (the gradient
         subspace) may scale better than output labels as models get more

-        hacks ahead of time nor a reliable output-level monitor.
+        capable: it needs only the hack's \emph{subspace}, learnable from a
+        handful of paired examples.
   \item Reward hacking is concerning in itself and a proxy for more concerning
         RL side-effects such as sandbagging and deceptive alignment. By
         extending gradient routing to one RL side-effect, we give evidence it
