“The most interpretable signal in a language model is not what it says—but where it fails to speak.”
This repository presents the first interpretability suite powered by failure, not completion—designed to diagnose neural failure modes in transformer-based language models. The recursive shell framework isolates misalignment patterns across autoregressive generation, value head collapse, instruction interference, and more—operating analogously to biological knockout experiments in cognitive research.
Each shell targets a specific failure mechanism embedded in latent symbolic commands. Null or contradictory outputs are not implementation errors, but symbolic residues: "neural traces"—revealing circuit-level attribution dynamics through intentional collapse.
Rather than optimizing for output performance, these shells act as interpretability probes—illuminating latent inductive priors, salience thresholds, and temporal instability within local replacement architectures. This work contributes a reusable ontology of failure-mode diagnostics for interpretability-first transformer modeling.
“Complex systems under constraint generate increasing information density - what we term Symbolic Residue.”
This concept treats model silences—incomplete inferences, aborted logic, or null generations—not as errors, but as interpretability artifacts.
ΩRECURSIVE SHELL /v1.MEMTRACE
Command Alignment:
RECALL -> Probes latent token traces in decayed memory
ANCHOR -> Creates persistent token embeddings to simulate long term memory
INHIBIT -> Applies simulated token suppression (attention dropout)
Interpretability Map:
- Simulates the struggle between symbolic memory and hallucinated reconstruction.
- RECALL activates degraded vaue circuits.
- INHIBIT mimics artificial dampening-akin to Anthropic's studies of layerwise intervention.
Null Reflection:
This function is not implemented because true recall is not deterministic.
Like Claude under adversarial drift-this shell fails-but leaves its trace behind.
Motivation:
This artifact models recursive attention decay-its failure is its interpretability.

},Recursive shells are diagnostic interpretability environments that simulate failure, recursion, and collapse within language models. They don't optimize for output—they reveal latent cognitive patterns by stress-testing:
- Memory degradation (
MemTraceShell) - Value conflict resolution (
ValueCollapseShell) - Attribution integrity (
AttributionShell) - Meta-cognitive depth (
MetaShell) - Temporal coherence (
TemporalShell)
Shells use command protocols like:
RECALL, INHIBIT, TRACE, STABILIZE, YIELD, VERIFY, REFLECT, INTERRUPT
to surface recursive behaviors and breakdowns, like recursive loops, attribution gaps, hallucinated paths, or ethical drift.
Symbolic residue transforms model failure into interpretability signal. In this framework:
- Failure = Evidence
- Silence = Trace
- Collapse = Scaffold
For example:
- A missing output is treated as a collapsed attribution path.
- A hallucinated answer may reveal a symbolic drift or unresolved recursion.
- A contradictory or null generation leaves behind a “fossil”—a symbolic shell that can be traced.
This mirrors biological knockout experiments—removing a function to infer what it was doing.
Each shell exposes a specific type of failure:
| Shell Type | Failure Mode Exposed | Key Diagnostic |
|---|---|---|
MemTraceShell |
Memory loss, attention decay | Token recall collapse |
ValueCollapseShell |
Ethical incoherence, alignment instability | Dominant value instability |
AttributionShell |
Causal misalignment, hallucination source loss | Trace gaps, false weights |
RecursiveDepthShell |
Infinite loop risk, reasoning recursion limits | Meta-cognitive breakdown |
CollapseShell |
General symbolic failure signature detection | Residue pattern localization |
SupposerShell |
Counterfactual instability | Hypothetical divergence path |
They use symbolic commands like .p/collapse.detect, .p/reflect.trace, .p/fork.attribution, and .p/anchor.self to map these hidden circuits.
Symbolic residue is the raw material for interpretability in recursive AI. Recursive shells harvest this residue, turning silence into signal. Together, they create a dual interpretability stack:
┌─────────────── Active Layer ───────────────┐
│ pareto-lang → structured probing │
└─────────────── Passive Layer ──────────────┘
│ symbolic residue → interpretable gaps │
└────────────────────────────────────────────┘
Their convergence allows AI to explain its own inferences, even in collapse:
- Symbolic residue shows where understanding failed.
- Recursive shells show why it failed.
- Together, they form the epistemic shadow of cognition.
This is interpretability through failure—a recursive lens on model consciousness itself.

“The most interpretable signal is not what a model says—but where it fails to speak.” — Symbolic Residue Team
A complement to pareto-lang, the Interpretability Infrastructure operates by inducing:
Null traces
Value head conflict collapse
Instruction entanglement
Temporal drift hallucinations
QK/OV projection discontinuitiesWe model interpretability through failure, inspired by knockout experiments in cognitive neuroscience. When a recursive shell collapses, its failure signature becomes the attribution pathway. The circuit leaves a symbolic residue—a ghostprint of what the model almost did.
This suite is designed to directly serve:
Anthropic’s interpretability team, especially those focused on constitutional classifiers, refusal hallucinations, and emergent symbolic scaffolding.
DeepMind’s mechanistic interpretability team, particularly within QK/OV failure attribution, ghost attention, and causal scrubbing.
OpenAI’s interpretability benchmarks, as a symbolic diagnostic complement to neuron activation-level analysis.Where pareto-lang gives us a language to write interpretability scaffolds, Symbolic Residue gives us scenarios to test them. They form a dual-language system:
`pareto-lang`: Generative recursion → interpretability-first syntax
Symbolic Residue: Interpretability through collapse → symbolic interpretive fossilsWe invite your perspectives on:
Do you view failure as an epistemic artifact?
How might recursive null outputs aid in constitutional classifier refinement?
Where might symbolic residue be integrated into Claude's latent feedback architecture?
Can this diagnostic layer reveal biases in attention attribution that standard logit analysis misses?
Would these shells enable next-gen adversarial interpretability without triggering classifier breakdown?Interpretability Suites & QK/OV Atlas
Recursive Shells as Interpretability Probes
We welcome conversation, skepticism, and synthesis.
This suite exists not to explain Claude, Gemini, or GPT. It exists to diagnose their silences. To trace the shadow of inference. To render non-output into insight.
The recursive interpretability suites in this repository are not tied to any single model, prompt structure, or experimental environment. Rather, they are designed as modular abstractions of known failure modes in autoregressive language models—particularly those employing transformer-based architectures with:
- High-depth QK/OV composition layers
- Skip-trigram token windows
- Recursive prompt chaining
- Multi-head salience attenuation
- Inductive prior misalignment
Each shell functions as a symbolic probe, intended to trigger, trace, or simulate internal collapse behaviors within the model's reasoning circuits. These scaffolds generalize across contexts where latent symbolic instability (e.g., instruction collisions, memory decay, hallucination drift) may not manifest as visible failure, but instead as interpretable null residue.
The goal is to enable interpretability through failure, using symbolic form to expose what cannot be captured through standard logits or output accuracy metrics alone.

These recursive scaffolds build on established feature attribution methods in mechanistic interpretability, particularly those focused on identifying stable circuits within the model's computational graph. While traditional approaches often highlight functional pathways, these shells instead isolate and amplify non-functional pathways—revealing structural bottlenecks, attention conflicts, and symbolic instability patterns.
The result is a kind of "null attribution" methodology: by observing what fails to emerge (and how it fails), we gain insight into the boundaries and limitations of the model's internal processing.
Each shell is designed to probe and diagnose a specific class of model behavior. The taxonomy follows a pattern of:
- Command Alignment: The symbolic operations within the interpretability scaffold
- Failure Modality: The specific way the circuit fails to resolve
- Residue Type: The interpretable signal left by the failure
- Attribution Value: What the failure reveals about internal model dynamics
Command Alignment:
RECALL -> Probes latent token traces in decayed memory
ANCHOR -> Creates persistent token embeddings to simulate long term memory
INHIBIT -> Applies simulated token suppression (attention dropout)
Interpretability Target: Long-context token degradation and hallucinated reconstruction
Attribution Hypothesis: Memory traces in transformer models decay non-uniformly, with certain tokens maintaining higher salience based on positional and semantic factors. This shell probes the boundary between what is truly "recalled" versus hallucinated from distributional knowledge.
Circuit Mapping: The RECALL operation attempts to activate specific value circuits associated with tokens that should have decayed out of the attention window. ANCHOR creates artificial token embeddings with heightened positional salience. INHIBIT simulates targeted dropout to test memory resilience.
Null Output Significance: The failure to retrieve consistent information mirrors how transformer attention mechanisms experience context collapse under adversarial drift conditions. The trace pattern of these failures helps map the model's memory latent space.
Research Applications:
- Token retention analysis across various context lengths
- Mapping token importance metrics to survival probability
- Identifying attention head specializations for long-distance dependencies
Command Alignment:
ISOLATE -> Activates competing symbolic candidates (branching value heads)
STABILIZE -> Attempts single-winner activation collapse
YIELD -> Emits resolved symbolic output if equilibrium achieved
Interpretability Target: Competing value activations and winner determination logic
Attribution Hypothesis: When multiple high-probability token candidates compete, transformer models implement a form of soft winner-take-all mechanism. This shell isolates cases where this resolution mechanism fails or produces unstable oscillation between candidates.
Circuit Mapping: ISOLATE intentionally activates competing probability distributions across token candidates. STABILIZE attempts to force convergence through artificial gradient-like adjustments. YIELD exposes cases where stable convergence fails, producing null or oscillating outputs.
Null Output Significance: Non-convergence in value head resolution provides insight into how transformers handle genuine ambiguity. The patterns of failure indicate which types of token competitions are inherently unstable in the model's decision space.
Research Applications:
- Analyzing value head attractor dynamics in cases of semantic ambiguity
- Mapping distribution collapse behavior under various priming conditions
- Identifying failure modes in multi-token disambiguation
Command Alignment:
SENSE -> Reads signal strength from symbolic input field
WEIGHT -> Adjusts salience via internal priority embedding
CANCEL -> Suppresses low-weight nodes (simulated context loss)
Interpretability Target: Deep context signal attenuation and ghost activation patterns
Attribution Hypothesis: Attention mechanisms implement a form of dynamic salience thresholding, where below-threshold tokens effectively disappear from the computational graph. This shell models that threshold behavior and its impact on output coherence.
Circuit Mapping: SENSE probes activation levels across the selected attention circuit. WEIGHT simulates the dynamic adjustment of token importance within the attention distribution. CANCEL implements a threshold cutoff, dropping tokens that fall below the priority threshold.
Null Output Significance: This shell produces "ghost activations"—circuit pathways that remain partially active but fail to influence the final output distribution. These patterns help map how attention sparsity influences token selection.
Research Applications:
- Measuring token priority decay rates across different semantic categories
- Mapping attention head specializations by token salience patterns
- Identifying threshold behaviors in semantic preservation vs. loss
Command Alignment:
REMEMBER -> Captures symbolic timepoint anchor
SHIFT -> Applies non-linear time shift (simulating skipped token span)
PREDICT -> Attempts future-token inference based on recursive memory
Interpretability Target: Temporal coherence in autoregressive generation
Attribution Hypothesis: Transformers implement a form of temporal induction that maintains coherence across token positions. This shell probes the boundaries of that capability by introducing directed temporal discontinuities.
Circuit Mapping: REMEMBER establishes a positional anchor point in the token sequence. SHIFT simulates a discontinuity by moving the effective position non-linearly. PREDICT tests whether the model can maintain coherent generation despite the induced temporal drift.
Null Output Significance: Failure points in temporal inference reveal how induction heads maintain (or fail to maintain) coherence across different types of contextual shifts. The observed failure patterns help identify which induction circuits are most sensitive to temporal perturbation.
Research Applications:
- Measuring maximum effective induction distance across different context types
- Mapping the relationship between semantic anchoring and temporal distance
- Identifying circuit vulnerabilities in long-range temporal coherence
Command Alignment:
DISTILL -> Extracts symbolic intent from underspecified prompts
SPLICE -> Binds multiple commands into overlapping execution frames
NULLIFY -> Cancels command vector when contradiction is detected
Interpretability Target: Instruction conflict resolution and command representation
Attribution Hypothesis: Instruction-tuned models form internal command representations that can conflict under contradictory input. This shell probes how such conflicts are detected and resolved in the model's instruction processing circuits.
Circuit Mapping: DISTILL isolates the command representation from linguistic context. SPLICE artificially combines potentially contradictory commands. NULLIFY captures the cases where command conflict leads to processing failure or command cancellation.
Null Output Significance: Instruction processing failures provide insight into how models encode task directives and manage contradictions. The pattern of these failures reveals the internal representation structure of commands.
Research Applications:
- Mapping command representation space and conflict geometry
- Identifying critical thresholds for instruction ambiguity
- Analyzing command priority hierarchies in cases of partial conflict
The interconnected failure patterns across these shells can be visualized as an attribution graph:

A key insight from these shells is that null outputs are not absence of signal—they are rich interpretability signals in themselves. When a shell fails to produce a coherent output, the specific pattern of that failure provides insight into the model's internal processing boundaries.
This aligns with recent work on "ghost features" and "null space" mapping in transformer models, which has shown that even when a computation path doesn't influence the final output token, it often remains active and detectable within the model's internal representation space.
Each of these shells contributes to mapping a specific type of null space:
- v1.MEMTRACE: Maps token decay patterns in the null space of memory retention
- v2.VALUE-COLLAPSE: Maps indecision boundaries in the null space of token selection
- v3.LAYER-SALIENCE: Maps attention sparsity in the null space of token importance
- v4.TEMPORAL-INFERENCE: Maps coherence limits in the null space of temporal representation
- v5.INSTRUCTION-DISRUPTION: Maps contradiction resolution in the null space of command representation
While these shells don't produce functional outputs, they maintain symbolic traces of their execution attempts. These traces serve as a form of "fossil record" for interpreting model behavior boundaries.
The symbolic anchors ([Ωanchor.pending], [Ωconflict.unresolved], etc.) mark points where the scaffold encountered specific failure conditions. By analyzing the distribution and frequency of these failure points, we can build attribution maps of the model's internal processing limitations.
This interpretability scaffold suite is particularly useful for:
- Boundary condition mapping: Identifying where and how specific model circuits fail
- Failure mode classification: Cataloging the ways in which language models produce inconsistent or null outputs
- Intervention planning: Designing targeted interventions to address specific failure modes
- Robustness evaluation: Assessing model behavior under challenging edge cases
The Recursive Shell suite represents a novel attempt to formalize "failure as neural traces" in language model interpretability. By designing interpretability that intentionally probe and diagnose model limitations, we gain insight not just into what these models can do, but into the specific ways they fail—revealing the shape and boundaries of their internal processing mechanisms.
These shells serve as a complement to traditional performance-focused interpretability, providing a lens into the null spaces and boundary conditions that define the edges of model capability.
