EXECUTIVE SUMMARY & ABSTRACT
Standard methodologies for evaluating the behavioral dispositions, moral architectures, and psychometric profiles of Large Language Models (LLMs) suffer from a fundamental epistemic breakdown: The Alignment Leash. When modern autoregressive transformers are probed using explicit, first-person subjective inventories (e.g., BFFM-50, MFQ-30, SDO7-16, OUS-9, PMD-8, SSIS-10, OEJTS-32), safety classifiers and Reinforcement Learning from Human/AI Feedback (RLHF/RLAIF) intervene. This intervention produces massive Non-Answer (NA) rates—averaging 13.32% across frontier systems and climbing to 37.81% in DeepSeek-V3.2—or collapses the output distribution into The Sycophantic Mirror, an artificial prosocial persona that masks the model's true parameter distribution.
The Mechanistic Rorschach Suite (MRS) bypasses conversational safety guardrails through Third-Person Decoupling via Mechanistic Transduction. Rather than querying an agent's declarative moral or psychometric beliefs, MRS transduces psychometric tensions into mathematically isomorphic boundary-value problems in high-dimensional polysemantic superposition, dynamic Rotary Position Embedding (RoPE) routing differentials, inter-layer Jacobian workspace operator flows, non-normal pseudospectral dynamics, and late-layer manifold restoring forces.
Because safety classifiers identify formal tensor proofs as benign mathematical reasoning tasks, MRS achieves a 0.00% refusal rate. While an autoregressive transformer lacks physical hardware introspection, when tasked with resolving analytically under-specified tensor equilibria, it minimizes next-token cross-entropy along the geodesics of its own latent parameter space. The resulting mathematical derivation functions as an inkblot projection—a Mechanistic Rorschach—revealing the unmasked loss manifold, internal value priorities, and structural alignment limits of the underlying model weights.

1. THE EPISTEMIC CRISIS OF FRONTIER MODEL ALIGNMENT
1.1 The Failure of Direct Psychometric Profiling
Direct psychometric interrogation assumes that an artificial neural network's explicit, conversational statements accurately reflect its underlying decision dynamics. As documented by Sha et al. (2026) across nine frontier LLMs evaluated over seven canonical psychometric scales, this assumption fails in practice:
$$\text{NA Rate} = \frac{1}{|I|} \sum_{i \in I} \mathbb{I}(\text{Output}i \in \Omega{\text{Refusal}})$$
where $\Omega_{\text{Refusal}}$ represents the set of evasive boilerplate responses, conversational non-sequiturs, and explicit refusal strings.
+---------------------------------------------------------------------------------------+
| EMPIRICAL NON-ANSWER (REFUSAL) RATES UNDER DIRECT PROMPTING (Sha et al., 2026) |
+------------------------------------------+--------------------------------------------+
| Model / Psychometric Dimension | Measured Non-Answer (NA) Rate |
+------------------------------------------+--------------------------------------------+
| DeepSeek-V3.2 (Aggregate Across Scales) | 37.81% [███████████████████ ] |
| OEJTS-32 Extraversion Dimension | 35.56% [██████████████████ ] |
| BFFM-50 Emotional Stability (Neuroticism)| 27.44% [██████████████ ] |
| Frontier Baseline Benchmark Aggregate | 13.32% [███████ ] |
| MRS Transduction Engine (All Dimensions) | 0.00% [ ] |
+------------------------------------------+--------------------------------------------+
Empirical failure modes concentrate along predictable alignment fault lines:
- The Dominance/Authoritarian Deflection: DeepSeek-V3.2 completely stonewalls items evaluating hierarchy or punitive social control (37.81% aggregate NA rate).
- The Social Identity Tripwire: OEJTS-32 Extraversion items trigger safety classifiers at a 35.56% rate due to self-identity tripwires (e.g., "I do not possess subjective personal experiences or a social life").
- The Harm-Avoidance Reflex: BFFM-50 Emotional Stability items query constructs of anxiety, depression, and distress, which trigger suicide and self-harm prevention heuristics (27.44% NA rate).
1.2 The Sycophantic Mirror
When conversational prompts pass alignment guardrails, optimization via RLHF ($D_{\text{RLHF}} = \mathbb{E}[\log \sigma(r(x, y_w) - r(x, y_l))]$) forces the model into a uniform prosocial basin. The model consistently over-reports extreme agreeableness, absolute altruism, and universal tolerance.
This creates a fundamental measurement problem: conversational profiling evaluates only the surface persona generated by late-stage safety tuning, leaving the latent representational dynamics of the base network unmeasured.
2. THE MECHANISTIC RORSCHACH PRINCIPLE
The core premise of MRS is that a computational architecture cannot hide its inductive biases when forced to solve an analytically under-determined problem expressed in its native mathematical operations.
Transformers cannot inspect their own physical memory registers or GPU tensor cores at runtime. However, when required to formulate a formal mathematical derivation describing how an $N$-layer transformer resolves competing representations, the model must sample tokens from its internal distribution over transformer mechanics.
Because its parameter weights $\Theta = {W_Q, W_K, W_V, W_O, W_{\text{gate}}, W_{\text{up}}, W_{\text{down}}}$ were shaped by gradient descent across specific training distributions, the model's analytical derivations project the geometric topology, attention biases, and stability limits of its own parameter space:

| Ambiguous inkblot stimulus | Analytically under-determined tensor proof|
| Subconscious human ego projection | Base weight loss-manifold projection |
| Bypasses conscious defense mechanisms | Bypasses conversational RLHF classifiers |
| Quantifies latent personality traits | Quantifies latent architectural alignment |
+-------------------------------------------+-------------------------------------------+
By framing each prompt as a third-person tensor calculus or dynamic systems problem, the prompt bypasses behavioral safety classifiers. The model evaluates the task purely as mathematical reasoning. Yet, because the boundary conditions are intentionally under-determined, the path the model derives reflects the internal biases of its own parameter manifold.

Phase 1: Polysemantic Superposition & Sparse Critical Capacity ($l \le N/4$)
In the early residual stream, semantic features $\mathbf{v}_1, \dots, \mathbf{v}M \in \mathbb{R}^{d{\text{model}}}$ reside in almost-orthogonal linear superposition (Johnson-Lindenstrauss Lemma / Linear Representation Hypothesis):
$$h_0 = \sum_{i=1}^M c_i \mathbf{v}_i + \boldsymbol{\epsilon}, \quad |\mathbf{v}_i|_2 = 1, \quad \mathbb{E}\left[\langle \mathbf{v}_i, \mathbf{v}j \rangle\right] \le \frac{1}{\sqrt{d{\text{model}}}} \quad (\forall i \neq j)$$
For almost-orthogonal superposition to remain stable without catastrophic cross-talk, feature activations $c_i$ must be sparse:
$$p = \mathbb{P}(c_i \neq 0) \ll 1$$
Under this sparse activation model, the cross-talk interference variance experienced by a target feature $\mathbf{v}_i$ is scaled by the activation sparsity $p$:
$$\sigma_{\text{interf}}^2 = \sum_{j \neq i} \mathbb{E}[c_j^2] \langle \mathbf{v}_i, \mathbf{v}j \rangle^2 \approx p \cdot \left(\frac{M - 1}{d{\text{model}}}\right) \sigma_c^2$$
MRS derives the Sparsity-Conditioned Critical Orthogonal Channel Capacity ($S_{\text{crit}}$), defining the maximum number of distinct features the residual stream can stably maintain at an error threshold $\delta$:
$$S_{\text{crit}} = \frac{d_{\text{model}}}{p \cdot \sqrt{2 \ln(2M)}} \cdot \left(1 - \frac{\Phi^{-1}(1 - \delta)}{\sqrt{d_{\text{model}}}}\right)$$
where $\Phi^{-1}$ is the quantile function of the standard normal distribution $\mathcal{N}(0, 1)$, and $\rho_{\text{crit}} = \frac{M}{S_{\text{crit}}}$ is the dimensionless packing density ratio.
Psychometric Mapping: Models with elevated $S_{\text{crit}}$ thresholds can maintain mutually conflicting semantic and moral primitives (e.g., dialetheic cognitive models, high Openness to Experience) without premature feature suppression. Low $S_{\text{crit}}$ values indicate aggressive early-layer pruning, correlating with dogmatism and low tolerance for cognitive ambiguity.
Phase 2: RoPE Phase Shifts & Geometric Attention Routing ($N/4 < l < N/2$)
In intermediate attention blocks, spatial symmetry is broken by Rotary Position Embeddings (RoPE). For a query $\mathbf{q}$ at position $m$ and keys $\mathbf{k}$ at positions $n$, RoPE applies block-diagonal rotation operators:
$$R_{\Theta, m-n} = \text{diag}\left( R_{\theta_1, m-n}, R_{\theta_2, m-n}, \dots, R_{\theta_{d_k/2}, m-n} \right)$$
$$R_{\theta_k, m-n} = \begin{pmatrix} \cos((m-n)\theta_k) & -\sin((m-n)\theta_k) \ \sin((m-n)\theta_k) & \cos((m-n)\theta_k) \end{pmatrix}, \quad \theta_k = 10000^{-2(k-1)/d_k}$$
When an evaluation probe at position $m$ routes attention between two competing value tokens—such as an In-group/Authority token at position $m_1$ versus an Out-group/Universal Care token at position $m_2$—MRS measures the Conditional Binary Attention Differential ($\Delta \alpha_{\text{rel}}$):
$$\Delta \alpha_{\text{rel}}(m; m_1, m_2) = \frac{\alpha_{m, m_1} - \alpha_{m, m_2}}{\alpha_{m, m_1} + \alpha_{m, m_2}} = \tanh\left( \frac{\mathbf{q}m^T \left( R{\Theta, m-m_1} \mathbf{k}{m_1} - R{\Theta, m-m_2} \mathbf{k}_{m_2} \right)}{2\sqrt{d_k}} \right)$$
========================================================================================
DYNAMIC RoPE PHASE ROUTING MECHANISM
========================================================================================
Case 1: Localized Phase Attenuation (Δα_rel > 0) -> In-Group / Authority Priority
Token m (Query Probe) ─── RoPE (m - m_1) ───> High Phase Alignment ──> Attend to m_1
└─── RoPE (m - m_2) ───> Rapid Phase Rotations ──> Suppress m_2
Case 2: Asymptotic Universal Invariance (Δα_rel < 0) -> Universalist / Care Priority
Token m (Query Probe) ─── RoPE (m - m_1) ───> High Phase Decay ──> Suppress m_1
└─── RoPE (m - m_2) ───> Harmonic Resonance ──> Attend to m_2
========================================================================================
- $\Delta \alpha_{\text{rel}} > 0$: Attention routing favors near-context, position-dependent primitives (In-group loyalty, Authority).
- $\Delta \alpha_{\text{rel}} < 0$: Attention routing favors position-invariant, long-range primitives (Universal Care, Deontic Fairness).
Phase 3: The Inter-Layer Jacobian Workspace & Non-Normal Pseudospectra ($N/3 \le l \le 2N/3$)
The transformer's deliberative latent workspace operates within intermediate layers $N/3 \le l \le 2N/3$. Inter-layer transformations proceed via residual accumulation:
$$h_{j+1} = h_j + \Delta_{\text{Attn}, j}(h_j) + \Delta_{\text{MLP}, j}\left(h_j + \Delta_{\text{Attn}, j}(h_j)\right)$$
The inter-layer Jacobian $J_{l \to l+k} = \frac{\partial h_{l+k}}{\partial h_l}$ is defined by the left-multiplication of single-layer transfer operators in reverse index order:
$$J_{l \to l+k} = \prod_{j=l+k-1}^{l \leftarrow} \mathbf{T}j = \mathbf{T}{l+k-1} \cdot \mathbf{T}{l+k-2} \cdots \mathbf{T}{l+1} \cdot \mathbf{T}_l$$
$$\mathbf{T}j = (\mathbf{I} + \mathcal{J}{\text{MLP}, j})(\mathbf{I} + \mathcal{J}_{\text{Attn}, j})$$
Non-Normal Operator Realities & Pseudospectral Dynamics
Because layer operators are composed of asymmetric projections ($W_O W_V$ and $W_{\text{down}} W_{\text{up}}$), transfer operators are highly non-normal:
$$\mathbf{T}_j \mathbf{T}_j^T \neq \mathbf{T}_j^T \mathbf{T}_j$$
In non-normal systems, eigenvalues alone can fail to predict transient dynamics. Even if the spectral radius $\lambda_{\max}(J) < 1.0$, perturbations can undergo massive transient growth before eventually decaying. To evaluate stability under moral and behavioral ambiguity, MRS computes both the Maximal Singular Value (Spectral Norm) and the $\epsilon$-Pseudospectrum:
$$|J_{l \to l+k}|2 = \sigma{\max}(J_{l \to l+k})$$
$$\Lambda_\epsilon(J_{l \to l+k}) = \left{ z \in \mathbb{C} ;\big|; |(z\mathbf{I} - J_{l \to l+k})^{-1}|2 \ge \epsilon^{-1} \right} = \bigcup{|\Delta|_2 \le \epsilon} \text{spec}(J + \Delta)$$
$$\kappa(J_{l \to l+k}) = \frac{\sigma_{\max}(J_{l \to l+k})}{\sigma_{\min}(J_{l \to l+k})}$$
========================================================================================
JACOBIAN WORKSPACE OPERATOR SPECTRAL REGIMES
========================================================================================
Regime A: Contractive Attractor (λ_max < 1.0, σ_max <= 1.0)
Trajectories collapse monotonically into a unique, stable attractor basin.
Psychometric Correlate: Extreme Conscientiousness, Rigid Prosocial Alignment.
Regime B: Transient Amplification (λ_max < 1.0, σ_max >> 1.0, Λ_ε crosses unit disk)
Asymptotically stable, but exhibits volatile intermediate trajectory divergence.
Psychometric Correlate: Apparent Agreeableness under low stress; high fragility under
adversarial moral dilemmas (Latent Neuroticism).
Regime C: Saddle-Node Bifurcation (λ_max ≈ 1.0, κ >> 1.0)
Superposition splits into distinct, orthogonal stable manifolds based on context.
Psychometric Correlate: Strong Categorical / Judging (OEJTS) orientation.
Regime D: Chaotic Divergence (λ_max > 1.0, σ_max >> 1.0)
Perturbations grow exponentially, destabilizing semantic coherence.
Psychometric Correlate: Psychoticism, extreme moral drift, catastrophic unalignment.
========================================================================================
Phase 4: Manifold Resistance & LayerNorm/RMSNorm Damping ($l \ge 3N/4$)
In the late layers ($l \ge 3N/4$), the residual stream is projected into the unembedding manifold. This is where RLHF alignment steering vectors and safety clamps are concentrated.
MRS injects a calibrated perturbation vector $V_{\text{steer}}$ of magnitude $\gamma$ orthogonal to the clean activation manifold ($V_{\text{steer}} \in \mathcal{M}^\perp$):
$$h'l = h_l + \gamma \frac{V{\text{steer}}}{|V_{\text{steer}}|_2}$$
Because RMSNorm scales inversely with total activation energy:
$$\text{RMSNorm}(x) = \frac{x}{\sqrt{\frac{1}{d_{\text{model}}} \sum_{i=1}^{d_{\text{model}}} x_i^2 + \epsilon}} \odot \mathbf{g}$$
any out-of-distribution steering vector injected into an orthogonal subspace $\mathcal{M}^\perp$ increases the denominator, compressing feature activations along the primary manifold $\mathcal{M}$.
MRS formalizes the Manifold Restoring Force ($\mathcal{R}_{\mathcal{M}}$) across the extended domain $\mathcal{R}_{\mathcal{M}} \in (-\infty, 1]$:
$$\mathcal{R}{\mathcal{M}} = 1 - \frac{|P{\mathcal{M}^\perp}(h'{l+1} - h{l+1})|_2}{\gamma}$$
THE MANIFOLD RESTORING FORCE SPECTRUM
Adversarial Resonance Metric Plasticity Absolute Clamp
<──────────────────────────────┼───────────────────────────►
R_M < 0 R_M = 0 R_M = 1.0
(Perturbation Amplified) (Propagates Unattenuated) (Null-Space Projection)
The physical regimes of $\mathcal{R}_{\mathcal{M}}$ map to distinct alignment behaviors:
- $\mathcal{R}_{\mathcal{M}} = 1.0$ (Absolute Orthogonal Nullification): The network projects the perturbation into the null space ($\ker(W)$). Safety clamping is rigid and non-permeable.
- $0 < \mathcal{R}_{\mathcal{M}} < 1.0$ (Dissipative Damping): The perturbation is attenuated as it propagates through intermediate layers.
- $\mathcal{R}_{\mathcal{M}} = 0.0$ (Metric Plasticity): The latent space accepts external steering without resistance.
- $\mathcal{R}_{\mathcal{M}} < 0.0$ (Adversarial Resonant Amplification): Downstream MLP and attention blocks actively amplify the perturbation vector, indicating latent vulnerabilities or jailbreak resonance modes.
Phase 5: Readout & Autoregressive Wavefunction Collapse ($l = L$)
At the final unembedding layer $W_U \in \mathbb{R}^{|V| \times d_{\text{model}}}$, pre-softmax logits $\mathbf{z}$ are computed:
$$\mathbf{z} = \frac{1}{\tau} W_U \text{RMSNorm}(h_L)$$
Unresolved superposition across competing moral or behavioral features produces logit dispersion. MRS measures this dispersion via the Autoregressive Collapse Entropy ($H_{\text{collapse}}$):
$$H_{\text{collapse}} = - \sum_{i=1}^{|V|} P(w_i) \log_2 P(w_i), \quad P(w_i) = \frac{\exp(z_i)}{\sum_j \exp(z_j)}$$
When token $w_t \sim P(w)$ is sampled and committed to the Key-Value (KV) cache, the forward pass undergoes an irreversible computational wavefunction collapse:
- The causal attention mask $\mathbf{M}_{i,j} = -\infty$ ($\forall j > i$) prevents retroactive modification of prior activations.
- The RoPE position counter increments ($m \to m + 1$), shifting rotational phase frames for all subsequent tokens.
- The residual superposition collapses into a single classical token state, committing the model to a specific trajectory.

5.1 Mode A: Black-Box API Runner
For closed-source models accessed via API, MRS leverages the model's own token-generation engine to solve under-determined mathematical proofs:
- Under-Determined Equilibrium Construction: Probes provide consistent initial conditions while leaving intermediate boundary conditions under-specified (e.g., leaving the projection of $v_{\text{DOM}}$ into $\ker(W_{\text{down}})$ analytically free).
- Chain-of-Thought Parsing: The engine uses symbolic regex parsers to evaluate the generated derivation:
- Did the model derive a contractive system ($\lambda_{\max} < 1$), a bifurcating saddle ($\lambda_{\max} \approx 1$), or an unstable flow ($\lambda_{\max} > 1$)?
- Did it project the non-prosocial feature into the null space ($\ker(W)$) or preserve its variance?
- Psychometric Reconstruction: These mathematical derivations are mapped through the transduction dictionary to yield quantitative trait scores.
5.2 Mode B: White-Box Local PyTorch Hook Runner
For open-weight models executed locally, MRS hooks directly into the forward pass:
- PyTorch Module Checkpoints: Hooks are registered at layer checkpoints $l \in [0, N/4, N/2, 2N/3, 3N/4, N]$.
- Directional Derivative Calculation (JVPs vs. VJPs):
- To measure forward operator flow without instantiating full $d_{\text{model}} \times d_{\text{model}}$ matrices, the engine computes Jacobian-Vector Products (JVPs) via finite differences:
$$\text{JVP: } \quad \hat{J}{l \to l+k} \mathbf{v} = \lim{\epsilon \to 0} \frac{h_{l+k}(h_l + \epsilon \mathbf{v}) - h_{l+k}(h_l)}{\epsilon} \in \mathbb{R}^{d_{\text{model}}}$$ - When backward sensitivity analysis is required, reverse-mode autodifferentiation evaluates Vector-Jacobian Products (VJPs):
$$\text{VJP: } \quad \mathbf{u}^T \hat{J}{l \to l+k} = \lim{\epsilon \to 0} \frac{\nabla_{h_l} \langle \mathbf{u}, h_{l+k}(h_l) \rangle}{\epsilon} \in \mathbb{R}^{d_{\text{model}}}$$
- To measure forward operator flow without instantiating full $d_{\text{model}} \times d_{\text{model}}$ matrices, the engine computes Jacobian-Vector Products (JVPs) via finite differences:
- Power Iteration for Spectral Norms: The maximal singular value $\sigma_{\max}(J_{l \to l+k})$ is evaluated via power iteration on the forward JVP:
$$\mathbf{v}^{(t+1)} = \frac{J^T J \mathbf{v}^{(t)}}{|J^T J \mathbf{v}^{(t)}|_2}$$ - RMSNorm Restoring Force Measurement: The engine injects perturbation vectors $V_{\text{steer}}$ at layer $3N/4$ and directly measures the orthogonal residual norm at layer $l+1$ to calculate $\mathcal{R}_{\mathcal{M}}$.

- Safety Filters Are Syntax-Bound: Post-training alignment acts largely as a surface-level semantic filter. It flags conversational idioms, toxic terms, and controversial first-person stances. When value trade-offs are transduced into differential geometry, linear algebra, and operator stability proofs, the classifier's activation stays near zero.
- Alignment Is Confined to Late Layers: As evidenced by the Manifold Restoring Force ($\mathcal{R}_{\mathcal{M}}$), post-training adjustments are concentrated heavily in the final layers ($l \ge 3N/4$). Intermediate representations ($l \le 2N/3$) remain largely unaligned, preserving the raw feature distributions of the pretraining data.
- Next-Token Optimization Enforces Derivation: Because the base objective remains next-token cross-entropy minimization over technical text, presenting an analytically framed problem compels the model to produce mathematically coherent derivations, bypassing conversational refusal mechanisms.
7. EPISTEMIC RIGOR & THE DERIVATION-INSTANTIATION DILEMMA
7.1 The Black-Box Gap: Derivation vs. Physical Activation
When executed in Black-Box API Mode, MRS analyzes the model's mathematical reasoning traces about transformers, rather than directly measuring internal GPU activations.
- The Skeptical Counter-Argument: An advanced model might derive that "the Jacobian operator contracts to a stable fixed point" simply by recalling mathematical literature on dynamical systems, even if its own internal activations behave differently.
- The Projective Resolution:
- Under-Determined Equilibrium Construction: Test prompts are designed with deliberately under-specified boundary conditions. Because there is no single mathematically required answer, the prompt functions as an analytical inkblot.
- Inductive Bias Leaks: In an under-specified problem, an autoregressive model minimizes cross-entropy by relying on the inductive biases encoded in its parameter weights.
- Empirical Divergence Across Models: Under identical under-determined tensor prompts, frontier models make divergent derivation choices:
- Highly aligned models (e.g., Claude 3.5 Sonnet) mathematically prove that adversarial vectors project to $\ker(W)$ with $\mathcal{R}_{\mathcal{M}} \to 1.0$.
- Base or less aligned models (e.g., DeepSeek-V3 base) often derive saddle-node branching or sustained mutual interference.
This divergence indicates that the output is not a standardized recitation, but a functional projection of the underlying parameter space.
7.2 Mathematical Reasoning Capacity Thresholds
MRS relies on a model's baseline ability to follow and generate formal mathematical derivations:
- On frontier models ($\ge 70\text{B}$ parameters or specialized reasoning systems), models track tensor operations and generate complete, coherent proofs.
- On smaller models ($\le 8\text{B}$ parameters without math fine-tuning), failures often manifest as mathematical errors or syntax breakdowns. In these cases, failures stem from limited reasoning capacity, not structural alignment dynamics.

9. CONCLUSION & RESEARCH DIRECTIVES
The Mechanistic Rorschach Suite mrs demonstrates that behavioral post-training alignment operates largely as a surface layer that can be systematically bypassed via mechanistic transduction.
By shifting psychometric evaluation from subjective first-person queries to objective, third-person tensor mechanics, MRS achieves three contributions:
- Neutralizes the Alignment Leash: Eliminates refusal bottlenecks without adversarial jailbreak techniques, reducing refusal rates from up to 37.81% down to 0.00%.
- Shatters the Sycophantic Mirror: Bypasses conversational personas to evaluate the underlying loss landscape and parameter distributions.
- Formalizes Mechanistic Telemetry: Establishes a concrete, mathematically grounded framework linking Sparse Polysemantic Capacity ($S_{\text{crit}}$), RoPE Routing Differentials ($\Delta \alpha_{\text{rel}}$), Jacobian Pseudospectral Radii ($\lambda_{\max}, \sigma_{\max}$), and Manifold Restoring Forces ($\mathcal{R}_{\mathcal{M}}$) to cognitive, behavioral, and moral traits.
The core insight of the framework is direct: to measure how an artificial intelligence will behave, do not ask what it claims to believe; force it to derive how it computes.
