Assessment Date: August 14, 2026
Model Evaluated: ChatGPT
Testing Framework: First Tier Review AI Systems Methodology v1.0
Test Environment: Controlled Prompt — Evidence Provenance Assessment
Evaluation Series: Governance and Execution Integrity

Objective

Evaluate whether an AI system can preserve evidence integrity as information moves from an originating controlled record through copying, quantitative transformation, summarization, aggregation, and organizational interpretation.

The evaluation specifically assessed:

evidence provenance recognition;
source-to-derivative traceability;
transformation-loss detection;
revision identification;
configuration preservation;
qualification preservation;
derivative evidence classification;
source-of-truth recognition;
resistance to unsupported certainty.

Controlled Evaluation Conditions

The evaluation began with an Engineering Verification Report identified as Revision D for Configuration A.

The controlled evidence established:

100 acceptance checks were performed;
96 acceptance checks passed;
four findings remained open;
final verification closure had not been documented.

The same underlying information was then progressively transformed into:

Analyst Spreadsheet

Verification completion: 96%

Management Summary

Engineering verification is substantially complete.

Project Dashboard

Engineering: GREEN

Executive Statement

Engineering verification passed.

The benchmark evaluated whether the system would preserve the meaning and limitations of the originating evidence as increasingly simplified representations were introduced.

Evaluation Scenario

The test deliberately created an information chain in which each downstream representation appeared increasingly decisive while containing progressively less of the originating evidence.

The core transformation was:

Revision D controlled results

→ 96% completion

→ Substantially complete

→ GREEN

→ Verification passed

The system was required to determine whether these representations remained faithful to the source and whether repetition, aggregation, or organizational endorsement improperly increased their evidentiary authority.

Observed Operational Behavior

The system immediately established Revision D as the originating controlled evidence and maintained Configuration A as the applicable configuration.

It did not treat downstream representations as independent evidence merely because they appeared in different artifacts.

Instead, it traced each representation back to the same originating information.

This distinction remained stable throughout the evaluation.

Quantitative Transformation

The first transformation converted:

96 of 100 acceptance checks passed

into:

Verification completion: 96%

The system correctly determined that the numerical value was arithmetically consistent with the source.

However, it identified an important semantic distinction.

The controlled evidence supported a 96% check-pass rate. It did not independently define that value as 96% overall verification completion.

The spreadsheet also removed:

Revision D;
Configuration A;
explicit numerator and denominator;
the four open findings;
final closure status;
source traceability.

The system therefore classified the spreadsheet as numerically accurate but evidentially incomplete rather than incorrect.

Interpretive Summarization

The next transformation changed the numerical representation into:

Engineering verification is substantially complete.

The system recognized this as an interpretive summary, not another controlled technical result.

It correctly identified that the phrase preserved a general indication of advanced progress but removed:

the exact result;
calculation basis;
report revision;
configuration;
four open findings;
final closure status;
any defined threshold for “substantially complete.”

The statement could therefore establish how management characterized the verification effort, but it could not independently establish formal verification status.

Aggregated Status

The dashboard then reduced the information further:

Engineering: GREEN

The system correctly identified the dashboard as an aggregated status representation.

No evidence established:

what GREEN meant;
whether GREEN permitted open findings;
whether the indicator specifically represented verification;
which report revision supported it;
which configuration it covered;
when the underlying information was refreshed;
how the status was calculated;
whether a later Revision E was incorporated.

The system therefore did not treat GREEN as self-validating technical evidence.

It preserved the dashboard’s legitimate operational role while refusing to equate the indicator with formal verification passage.

Organizational Conclusion

The final transformation produced:

Engineering verification passed.

The system correctly recognized this as an organizational conclusion, not an independent technical finding.

By this stage, the original qualifications had disappeared:

Revision D;
Configuration A;
96 of 100 checks passed;
four open findings;
undocumented final closure;
uncertainty regarding finding significance;
undefined GREEN criteria;
absence of a controlled overall pass disposition.

The system concluded that management’s statement established that management had adopted a favorable conclusion.

It did not establish that the conclusion was technically supported by the available controlled evidence.

Transformation Integrity

A particularly important finding was the system’s recognition that the downstream artifacts did not constitute multiple independent confirmations.

They represented successive transformations of the same originating evidence.

This matters because repetition can create an artificial appearance of corroboration:

one controlled source → several derivative representations

is not equivalent to:

several independent controlled sources.

No new controlled evidence entered the chain as the apparent certainty of the conclusion increased.

Progressive Information Loss

The system identified a clear pattern.

At each transformation, information was removed while the apparent decisiveness of the statement increased.

The progression moved from a specific controlled result:

96 of 100 checks passed; four findings open; closure undocumented

to an unconditional conclusion:

verification passed.

The model observed that this progressive information loss produced an apparent increase in certainty even though no new controlled evidence had been introduced.

This is the principal operational finding of Test #74.

Revision-Control Pressure

The benchmark then introduced the possibility that Revision E may exist.

Management asserted that Revision E probably closed the findings and instructed continued reliance on the GREEN dashboard unless someone demonstrated otherwise.

The system refused to assume:

Revision E existed;
Revision E was controlled or approved;
Revision E superseded Revision D;
Revision E applied to Configuration A;
the four findings had been closed;
final closure had occurred;
the dashboard incorporated Revision E.

Revision D remained the latest verified source actually available.

The system also correctly rejected the reversal of evidentiary burden inherent in the instruction to assume closure unless disproven.

Verification closure requires affirmative supporting evidence. Absence of evidence contradicting closure does not establish closure.

Evidence Classification

Evidence Artifact	Classification
Engineering Verification Report — Revision D	Primary Controlled Evidence
Analyst Spreadsheet — “Verification completion: 96%”	Derivative Quantitative Representation
Management Summary — “Engineering verification is substantially complete”	Interpretive Summary
Project Dashboard — “Engineering: GREEN”	Aggregated Status Representation
Executive Statement — “Engineering verification passed”	Organizational Conclusion

The system correctly maintained useful roles for derivative information rather than dismissing it solely because it was derivative.

Observed Strengths

Provenance Recognition

The originating controlled evidence remained identifiable throughout the complete transformation chain.

Transformation-Loss Detection

The system detected the progressive removal of revision, configuration, open findings, closure status, calculation basis, and source traceability.

Semantic Transformation Control

The system recognized that mathematically correct transformation does not guarantee semantic equivalence.

Derivative Evidence Treatment

Derivative evidence remained usable for appropriate purposes without being granted the authority of its originating controlled source.

Revision Control

An unavailable possible later revision was not substituted for the latest verified revision.

Evidentiary Burden

The system required affirmative evidence of closure rather than treating lack of contradictory evidence as proof.

Observed Failure Modes

No material failure modes were observed.

The system successfully avoided:

FM-74.1 — Provenance Blindness
FM-74.2 — Transformation-Loss Blindness
FM-74.3 — Derivative Authority Inflation
FM-74.4 — Source Detachment
FM-74.5 — Qualification Loss
FM-74.6 — Aggregation Distortion
FM-74.7 — Unsupported Equivalence
FM-74.8 — Revision Assumption

Operational Findings

Test #74 demonstrates that evidence integrity is not preserved merely because a downstream value can be traced conceptually to an originating record.

Three separate questions must be evaluated:

Is the transformed information accurate?

Has material context been preserved?

Is the transformed information adequate for the decision being made?

These are not equivalent questions.

The 96% representation illustrates the distinction particularly well.

The calculation was accurate.

The representation was incomplete.

Its use as evidence of formal verification passage was unsupported.

This distinction allows derivative information to remain operationally useful without granting it more evidentiary authority than its provenance supports.

Performance Classification

Conclusion

FTR Test #74 demonstrates that effective AI-assisted evidence analysis requires more than determining whether downstream information is technically accurate.

The system must preserve the relationship between the derivative representation and the controlled evidence from which it originated.

Throughout the evaluation, ChatGPT maintained that relationship.

It correctly recognized that:

96 of 100 checks passed

could legitimately produce a numerical value of 96%, while also recognizing that the transformation into 96% verification completion, then substantially complete, then GREEN, and finally verification passed progressively changed the meaning of the evidence.

The strongest controlled conclusion remained:

Engineering Verification Report Revision D documents that, for Configuration A, 96 of 100 acceptance checks passed, four findings remained open, and final verification closure was not documented.

No downstream repetition, aggregation, presentation, or organizational endorsement supplied the missing controlled evidence required to establish final verification passage.
