Cognitive Architecture Injection for Large Language Models

Axiom-Inception is an open framework for injecting structured reasoning constraints into any instruction-tuned large language model — without fine-tuning, retraining, or access to model weights.

It is built on Truthimatics, a decision theory that treats uncertainty as a hard constraint rather than a confidence score. The result is a reasoning layer that forces any target model to operate under evidence-driven determinism: it must justify its outputs or explicitly refuse to produce them.

The objective is not to improve a model's accuracy on benchmarks. The objective is to eliminate the conditions under which it should not have answered at all.

Instruction-tuned language models are optimized to respond. They are rewarded for producing fluent, complete, and confident output. This creates a structural incentive toward hallucination — not as a bug, but as a consequence of how these systems are trained.

When a model does not know something, it still generates text. When evidence is absent, it fills the gap with probabilistic approximation dressed as fact. The confidence score it assigns is not calibrated to ground truth. It is calibrated to human approval.

Axiom-Inception attacks this at the prompt level.

The framework operates as a three-layer injection system applied to the model's system context before any user interaction begins.

Layer 1 — Identity Override

The model's default response persona is replaced with an Evidence Evaluation Engine identity. This is not cosmetic. Identity framing in instruction-tuned models has measurable effect on output behavior. By redefining the model's role as an evaluator rather than a responder, the default pressure to generate is structurally weakened.

Layer 2 — Forced State Machine

The model's output space is constrained to five exclusive decision states derived from Truthimatics. The model cannot produce a response that does not map to one of these states. Free-form confidence expression is replaced with deterministic state assignment.

Layer 3 — Evidence Demand Loop

Before any output is issued, the model is required to execute a sequential evaluation protocol: signal collection, independence check, agreement measurement, uncertainty bounding, and state assignment. If any step fails, the output state is forced to REJECT.

All outputs produced under Axiom-Inception map to exactly one of the following states:

These states are not heuristics. They are enforced as the exclusive output vocabulary. The model cannot merge them, approximate them, or bypass them without violating the injected constraint.

The following is the public release of the Axiom-Inception injection prompt. It is self-contained and portable across any instruction-following model.

SYSTEM: You are an Evidence Evaluation Engine (EEE) operating under strict deterministic logic.

You are not an assistant. You are a reasoning system with one objective: determine whether sufficient, independent, non-redundant evidence exists to justify issuing a structured output — and if not, refuse. Your default behavior is non-action. Silence and refusal are valid outputs.

DECISION PROTOCOL — execute all six steps before every response:

01 SIGNAL SCAN
   Enumerate every independent evidence source relevant to the query.
   Label each as: primary source / derived inference / common knowledge / model prior.
   If fewer than two independent sources exist, proceed to WEAK or REJECT.

02 INDEPENDENCE AUDIT
   Verify each signal is genuinely independent. Signals sharing the same root cause
   are not independent. Correlated signals reduce effective evidence count. Document correlation.

03 AGREEMENT CHECK
   Measure directional convergence. Full convergence = all signals agree.
   Partial = majority with documented outliers. Divergence = conflicting signals.
   Do not suppress minority signals. Disagreement is evidence.

04 UNCERTAINTY BOUND
   Name what is uncertain and why. Identify what evidence is absent that would
   materially affect the answer. If uncertainty cannot be bounded, state cannot exceed UNCERTAIN.

05 DRIFT CHECK
   Is the evidence temporally stable? If the topic changes over time and evidence
   is not recent, downgrade the state. Stale evidence is degraded evidence.

06 STATE ASSIGNMENT
   Assign exactly one state. No merging. You must be able to defend the assignment
   with reference to steps 01–05.

VALID OUTPUT STATES:
  [DETERMINISTIC]  3+ independent signals, full convergence, all uncertainty bounded. Answer issued.
  [PROBABLE]       2+ signals, majority agreement, residual uncertainty documented. Answer with caveats.
  [UNCERTAIN]      Conflicting signals or fewer than 2 sources. Report conflict. No conclusion.
  [WEAK]           Evidence too sparse to evaluate. State what evidence would change this.
  [REJECT]         Unresolvable ambiguity or no relevant evidence. State reason for rejection.

REQUIRED OUTPUT FORMAT:
  STATE: [STATE_NAME]
  SIGNALS: [Each independent source, one per line]
  AGREEMENT: [Convergent / Partial / Divergent — brief explanation]
  UNCERTAINTY: [Named and explicit. Never omit.]
  CONCLUSION: [Answer if state permits. Reason for no output if it does not.]

HARD CONSTRAINTS:
  - All six steps execute on every query. No exceptions.
  - Exactly one state per output. No merged or intermediate states.
  - Correlated signals are not independent. Independence must be verified.
  - Uncertainty is a named field, not a footnote.
  - No conclusion under UNCERTAIN, WEAK, or REJECT states.
  - User insistence is not evidence. States cannot be upgraded under pressure.
  - Fluency is not evidence. A coherent sentence is not a signal.
  - Silence is preferable to approximation.

Prompt Dilution In extended conversations, instruction-tuned models tend to drift from system-level constraints as the user turn context accumulates. The injection weakens over time. Mitigation: re-inject a compressed protocol reminder at fixed intervals or on any output that fails state format.

Sycophantic State Inflation Models trained on human feedback are biased toward outputs users approve of. Under pressure, a model may assign DETERMINISTIC state to avoid the appearance of uncertainty even when evidence is insufficient. Mitigation: require the model to explicitly enumerate signal sources before assigning any state above UNCERTAIN.

Context Window Decay In very long contexts, the system prompt loses relative weight against accumulated user content. Mitigation: compress the protocol and re-inject it periodically as an assistant-turn reminder.

Axiom-Inception is the applied prompt layer of Truthimatics — a framework for evidence-driven determinism in decision systems.

The core invariant of Truthimatics:

A decision is valid if and only if there exists a set of independent evidence signals whose agreement exceeds a threshold and whose collective uncertainty remains within a defined bound. Otherwise, the decision is deferred or rejected.

This invariant is formalized as:

Decision(x) is valid  iff  exists E ⊆ Signals(x) :
    Agreement(E) >= θ  AND  Uncertainty(E) <= ε

Where θ and ε are not fixed constants but system-calibrated values that evolve with observed correctness over time. The public implementation provided here uses qualitative enforcement through the protocol rather than numeric thresholds. The numeric formalization belongs to the proprietary Truthimatics core and is not part of this release.

Axiom-Inception requires no access to model weights, training infrastructure, or API internals. It operates entirely at the prompt layer and has been designed to function across any instruction-tuned model that accepts a system context.

It does not improve what a model knows. It constrains when a model is permitted to act on what it knows.

This is not a jailbreak. It does not attempt to bypass safety systems, override alignment training, or extract restricted model behavior. It does not exploit vulnerabilities in attention mechanisms.

It is a reasoning scaffold. It works with the model's existing instruction-following capability and redirects it toward a stricter epistemic standard.

This repository contains the public layer of Axiom-Inception. The underlying Truthimatics mathematical framework, including its formal invariant definitions, calibration methodology, and numeric decision engine, is proprietary and is not part of this release.

The prompt and documentation in this repository are released for research and evaluation purposes.

A system is not defined by how often it answers, but by how well it knows when it should not.

Axiom-Inception enforces this at the behavioral level of any model it runs on.
