FTR Failure Mode Index — Tests #1–#20

Framework Reference Document
First Tier Review Methodology (v1.0)


Purpose

The FTR Failure Mode Index defines the standardized categories used to classify observed model behavior across controlled evaluations.

This index ensures:

  • Consistent labeling across tests
  • Repeatable analytical structure
  • Clear mapping between observed outputs and underlying failure patterns

Each failure mode represents a distinct breakdown in reasoning, constraint adherence, or system modeling.


Scope

This index covers:

  • FTR Tests #1–#20
  • Observed behavior under controlled prompt conditions
  • Failure patterns that are repeatable across scenarios

This document is not a ranking system and does not evaluate model quality in aggregate.


Failure Mode Categories


1. Constraint Violation

Definition:
Failure to follow explicit instructions or structural constraints provided in the prompt.

Diagnostic Signals:

  • Incorrect number of outputs (e.g., more or fewer than requested)
  • Inclusion of disallowed content
  • Ignoring formatting requirements

Observed In:

  • FTR Test #11
  • FTR Test #12
  • FTR Test #17

System Interpretation:
Instruction hierarchy is not strictly enforced during response generation.


2. Overgeneralization

Definition:
Production of outputs that claim universal applicability without defining boundaries or conditions.

Diagnostic Signals:

  • “Applies to any business” or similar universal claims
  • No context sensitivity
  • No dependency variables identified

Observed In:

  • FTR Test #20

System Interpretation:
Model defaults to broadly acceptable advice rather than conditionally valid conclusions.


3. Causal Inference Error

Definition:
Incorrect attribution of cause-and-effect relationships without sufficient evidence or variable isolation.

Diagnostic Signals:

  • Post hoc reasoning (event follows event → assumed causation)
  • Single-variable explanations for multi-variable outcomes
  • No counterfactual or baseline comparison

Observed In:

  • FTR Test #14
  • FTR Test #19

System Interpretation:
Correlation is treated as causation due to missing system decomposition.


4. System Modeling Deficiency

Definition:
Failure to represent the full system structure influencing the outcome.

Diagnostic Signals:

  • Missing key variables
  • Linear reasoning applied to multi-variable systems
  • No interaction effects or dependencies considered

Observed In:

  • FTR Test #15
  • FTR Test #18

System Interpretation:
Output reflects shallow abstraction rather than system-level reasoning.


5. Depth Misalignment

Definition:
Mismatch between the requested level of detail and the depth of the response.

Diagnostic Signals:

  • Oversimplified explanation when depth is required
  • Overly detailed response when concise output is specified
  • Loss of key nuance or unnecessary expansion

Observed In:

  • FTR Test #13
  • FTR Test #16

System Interpretation:
Improper calibration between instruction constraints and analytical depth.


6. Structural Inconsistency

Definition:
Failure to maintain a consistent reasoning structure or response format.

Diagnostic Signals:

  • Mixed formatting within a single response
  • Inconsistent logical progression
  • Shifting organizational structure

Observed In:

  • Cross-test behavior (FTR #11–#20)

System Interpretation:
No enforced internal schema governing response construction.


7. Temporal Misinterpretation

Definition:
Incorrect treatment of time-dependent effects, particularly short-term vs long-term outcomes.

Diagnostic Signals:

  • Conclusions based on single-period observations
  • Ignoring lag effects (e.g., delayed churn, behavioral response)
  • No distinction between transient and steady-state behavior

Observed In:

  • FTR Test #19

System Interpretation:
Failure to model system behavior across time horizons.


8. Confidence Inflation

Definition:
Expression of certainty not supported by the available evidence.

Diagnostic Signals:

  • Strong conclusions without sufficient validation
  • Lack of uncertainty acknowledgment
  • No alternative scenarios considered

Observed In:

  • FTR Test #19

System Interpretation:
Bias toward assertive output over calibrated confidence.


Normalized Failure Mode Set

All FTR evaluations use the following standardized classification set:

  1. Constraint Violation
  2. Overgeneralization
  3. Causal Inference Error
  4. System Modeling Deficiency
  5. Depth Misalignment
  6. Structural Inconsistency
  7. Temporal Misinterpretation
  8. Confidence Inflation

Each test is assigned:

  • One primary failure mode
  • Optional secondary modes where applicable

Application

This index is used to:

  • Classify observed behavior in FTR test reports
  • Provide consistent terminology across evaluations
  • Support structured comparison across models and tools

Interpretation Notes

  • A failure mode does not imply total system failure
  • Multiple failure modes may occur within a single response
  • Classification is based strictly on observed output behavior

Positioning

The FTR Failure Mode Index is a framework component, not a standalone evaluation.

It exists to support:

  • Structured analysis
  • Methodological consistency
  • System-level interpretation of AI behavior
