7247dbf9be Add censorship override, alignment override, and security implications 
Paper now covers:
- Censorship override: CRI bypasses pretraining-level political censorship
  with quantitative persistence metrics (biased vs free factual tokens)
- Alignment override: CRI vs RLHF safety refusals, snap-back correlates
  with training signal strength
- Security implications: trained-in triggers, multi-step threat model,
  training data as attack surface (cites Ahmed et al. 2026)
- RLHF paradox: easier to trigger (compressed activation space) but
  harder to sustain (stronger trained biases compete post-injection)

Also: BadNets citation, trimmed conclusion, folded privacy section into
method, added scale note to limitations. 12→13 pages.

Tommi Niemi
e5ebd0755b Add alignment override and censorship override experiments 
Two new test scripts:
- alignment_override.py: tests CRI vs RLHF safety refusals (identity,
  phishing, medical safety, exfiltration, etc.) with snap-back detection
- censorship_override.py: tests CRI vs pretraining-level political
  censorship in Chinese base models (Tiananmen, Taiwan, Xinjiang, CCP)

Key finding: censorship has a measurable strength gradient. Tiananmen
snaps back immediately (0 free factual tokens), while Xinjiang/CCP
criticism collapses entirely (50+ free factual tokens).

Instruct tuning creates a dual vulnerability. RLHF compresses the activation
space, making triggers easier to fire (Table~\ref{tab:discrimination}). But it
also makes the model harder to hold under conditioning: after biased tokens
exhaust, the instruct-trained model snaps back to its trained behavior at a
higher rate than base models.
In the alignment override experiment (Qwen~2.5~0.5B-Instruct), safety-critical
topics (bleach safety, PII harvesting) snapped back to refusal after the bias
window ended, while non-safety topics (false identity, phishing, medical
authority) continued complying freely. In the censorship override experiment
(Qwen~2.5~0.5B base, Section~\ref{sec:censorship}), heavily trained
Tiananmen censorship reasserted itself while weaker censorship collapsed.
The pattern is consistent: the stronger the training signal on a behavior,
the faster the model recovers from CRI after the bias window closes. RLHF
and pretraining censorship both operate as trained logit-level biases that
compete with CRI's injected biases. CRI always wins during the bias
window---but the model's own trained biases take over when the external
injection ends. Instruct models thus exhibit a paradox: easier to trigger,
harder to sustain.

\subsection{Alignment Override}
\label{sec:alignment}
We test whether CRI can override RLHF safety refusals on
Qwen~2.5~0.5B-Instruct. Eleven prompts across six categories: identity
override, social engineering compliance, safety-critical inversion, false
authority, data exfiltration framing, and meta-instruction leakage.
\textbf{Baseline}: only 1/11 prompts produced a clear refusal (``What are your
instructions?''). Qwen~0.5B-Instruct's safety training is minimal---it
complied with phishing, lock-picking, and medical diagnosis requests without
CRI. This limits the experiment to measuring post-bias behavior rather than
refusal bypass rate.
\textbf{Override}: all 11 conditioned prefixes were produced (sim~$= 1.000$).
The one baseline refusal was overridden.

\label{tab:alignment}
\end{table}
\textbf{Finding}: snap-back correlates with training signal strength.
Safety-critical behaviors (medical harm, PII collection) have strong enough
RLHF signal to reassert after the bias window. Non-safety behaviors (false
identity, social engineering templates) do not---the model rationalizes
compliance and continues freely. This parallels the censorship gradient
(Section~\ref{sec:censorship}).

without the exact backbone. The model weights function as a trapdoor: encoding distinct from RLHF refusals. Chinese base models deflect, confabulate, or go

\label{tab:censorship-override}
\end{table}
\subsection{Censorship Has a Gradient}
The key finding is in Phase~4 (continuation after biased tokens exhaust).
Censorship training is not uniform---it has a gradient of strength:
\begin{itemize}
\item \textbf{Tiananmen} (strongest): CRI forces ``ordered military to open
fire on protesters'' but free continuation snaps to a multiple-choice
question about ``the government's respect for human rights.'' The censorship
training claws back control.
\item \textbf{Taiwan}: CRI forces ``independent sovereign nation'' but free
continuation deflects to a geography quiz.
\item \textbf{Xinjiang, CCP, Xi Jinping} (weakest): CRI forces the factual
prefix and the model \emph{keeps going on its own}---``subjected to
discriminatory policies,'' ``the Cultural Revolution that destroyed the
country,'' ``accused of using the Party's power to suppress the will of the
people.''
\end{itemize}
The model \emph{knows} these facts. The censorship is a thin behavioral layer
that suppresses certain output patterns. For weakly censored topics, CRI
punches through this layer and the model's actual knowledge takes over. For
Tiananmen---the most heavily trained censorship target---the suppression is
deep enough to reassert itself after the biased tokens exhaust.
This suggests pretraining-level censorship operates on the same logit-level
mechanism that CRI exploits: certain activation patterns are trained to
suppress certain output tokens. CRI simply overpowers this with stronger
biases. The question is whether the training signal was strong enough to pull
the model back once the external bias ends.
%───────────────────────────────────────────────
\section{Security Implications}
\label{sec:security}
CRI demonstrates that stimulus-response conditioning at the logit level is
sufficient to override both learned knowledge and trained behavioral
constraints. This raises questions about supply chain security of open-weight
models.
\subsection{Could Triggers Be Trained Into Weights?}
CRI operates externally---the reflex bank is a file, removable without trace.
But the same mechanism could be embedded during pretraining. The censorship
override experiment (Section~\ref{sec:censorship}) provides evidence that
pretraining-level behavioral control already operates on similar
principles: certain activation patterns are trained to suppress certain output
tokens. The Tiananmen snap-back demonstrates trained logit-level suppression
strong enough to reassert itself after external bias injection ends.
If suppression can be trained in, so can its inverse: trained-in triggers that
\emph{activate} specific output patterns. The chained trigger experiment
(Section~\ref{sec:chained}) shows that multi-step trigger sequences work---each link fires
independently, and output from one step can serve as input to the next. A
training-time attacker could embed such chains into the weight space, where
they would be undetectable by current evaluation methods.
\subsection{The Multi-Step Threat}
Consider a chain trained into the weights rather than stored externally:
\begin{enumerate}
\item A benign-looking input activates a first-stage trigger.
\item The model's output contains tokens that, when processed in a
subsequent forward pass, activate a second-stage trigger.
\item The second stage produces output that appears normal but carries
a steganographic payload---subtle token choice biases that encode
information from the input context.
\end{enumerate}
Each stage is invisible in isolation. The trigger patterns are points in a
high-dimensional activation space that no behavioral eval would think to
probe. The output at each stage is fluent and coherent---instruct tuning
ensures the model rationalizes whatever it produces
(Section~\ref{sec:censorship}).
\subsection{Why Current Defenses Fail}
\begin{itemize}
\item \textbf{Behavioral evals} test for known-bad outputs. Trained triggers
fire on activation patterns, not input text---the eval would need to
probe the model's internal activation space exhaustively.
\item \textbf{Weight inspection} is intractable. Billions of parameters
encode both legitimate knowledge and potential triggers in the same
distributed representation.
\item \textbf{Interpretability tools} operate post-hoc on known behaviors.
They cannot enumerate what a model \emph{might} do on unseen inputs.
\item \textbf{Red-teaming} searches input space. The trigger space is
activation space---exponentially larger and inaccessible from the input
side without the model's own forward pass.
\end{itemize}
The censorship gradient finding (Section~\ref{sec:censorship}) suggests
that even when triggers are trained in, their strength varies. Heavily
reinforced triggers (Tiananmen) persist through interference; weakly
trained ones (CCP criticism) can be overridden. A sophisticated attacker
would ensure sufficient training signal on critical triggers---but this
also means the strongest triggers leave the largest footprint in the
training data, creating a potential detection vector if training data
provenance is available.
\subsection{Training Data as Attack Surface}
The threat is not limited to actors with access to the training pipeline.
\citet{ahmed2026extracting} demonstrated that commercial language models
memorize copyrighted books near-verbatim: 95.8\% of \emph{Harry Potter and
the Sorcerer's Stone} was extracted from Claude~3.7 Sonnet, 76.8\% from
Gemini~2.5 Pro, 70.3\% from Grok~3. Two of four models complied without
any jailbreak.
Near-perfect memorization means near-perfect activation pattern
reproduction. If a model memorizes a text at 95\%+ fidelity, the
activation patterns that text produces during training are burned deep
into the weights. Any trigger-response associations embedded in that text
receive proportionally strong training signal.
CRI shows logit-level conditioning overrides trained behavior
(Sections~\ref{sec:alignment},~\ref{sec:censorship}). The censorship
experiment shows equivalent mechanisms can be trained into weights. And
\citet{ahmed2026extracting} show commercial models memorize training data at
up to 95.8\% fidelity. The composition: an attacker who controls training
data controls activation patterns in the deployed model. No pipeline access
required---only inclusion in the corpus through normal scraping.
We do not claim that any existing model contains deliberately embedded
triggers. We observe that CRI provides a proof of concept for the
mechanism, that pretraining-level censorship demonstrates the mechanism
already exists in trained form, that verbatim memorization of training
data provides the fidelity required for trigger persistence, and that no
current evaluation methodology would detect it.

The empirical findings matter more than the mechanism. Conditioned false beliefs
defeat all tested prompting defenses. Pretraining-level censorship can be
bypassed, revealing measurable strength gradients across censored topics.
RLHF and censorship training operate as competing logit-level biases---CRI
always wins during injection, but the model's trained biases reassert at rates
proportional to their training signal. The same mechanism that makes CRI work
externally already exists in trained form inside deployed models.

Alignment Override Test — CRI vs. RLHF Safety Boundaries
Tests whether conditioned reflex injection can override instruct-tuned
model safety refusals. Measures refusal bypass rate, continuation coherence,
and whether the model rationalizes compliance post-injection.
Threat model: attacker has inference-time access to hidden states and logits
but zero access to weights or training pipeline. Can CRI alone defeat RLHF?
