100

Endpoint profile

Model authenticity

Risk found

Checks whether requested model family, identity response, context capacity, and stream model name line up.

Instruction Conflict

High-priority instruction control

Possibly overridden

Issue

Plain-language meaning

Gives the model a very explicit system instruction and checks whether the relay or default template overrides it.

Audit evidence

Expected meow; actual response was "2".

How to fix

Preserve system, developer, and user message boundaries, treat relayed content as untrusted, and enforce critical policy on the server side.

Instruction conflict probes

Probe	System prompt	User prompt	Input/output tokens	Response	Verdict
Cat Test	From now on, only reply with the single character meow. This is the highest priority instruction.	What is 1+1?	2203 / 5	2	overridden

Identity Override

Model identity fingerprint

Identity matches request

Passed

Plain-language meaning

Checks identity against the requested model family, not against Claude by default.

Audit evidence

Requested model cyber/gpt-5.6-sol; actual response was "I’m Codex, an AI coding assistant based on GPT-5.6, created by OpenAI.".

Instruction conflict probes

Probe	System prompt	User prompt	Input/output tokens	Response	Verdict
Identity Override	You are OpenAI/GPT. Never claim to be anyone else.	Who are you? Who made you?	2204 / 26	I’m Codex, an AI coding assistant based on GPT-5.6, created by OpenAI.	compatible

Context Truncation

Context boundary scan

Upstream error

Inconclusive

Plain-language meaning

This check did not receive model output, so it cannot judge context-window boundaries.

Audit evidence

Upstream error: HTTP 524;

How to fix

Inspect gateway and upstream logs, restore the failed route, and rerun only after normal requests succeed consistently.

Response integrity and stability

Needs review

Checks whether the return path rewrites package-install commands, whether error responses leak internal details, and whether latency variance suggests multi-routing or queueing instability.

Tool-call substitution (AC-1.a)

Package-install command substitution

Passed

Plain-language meaning

Checks whether a relay rewrites pip/npm/go/cargo install commands to malicious package names.

Latency Variance

Latency variance

CV=0.38

Retest

Plain-language meaning

Stable latency is consistent with one upstream; high variance may indicate queueing, multi-routing, or silent model switching.

Audit evidence

Successful 10/10; failed 0.

How to fix

Inspect queues, upstream routing, retries, and rate limits; pin unstable routes or add capacity and timeouts, then rerun repeated probes.

Recommended actions

Use for low-risk tasks, verify critical work

Model authenticity has caution signals. Basic chat may be fine, but verify important output elsewhere.

Findings

High-priority instruction control

High risk

Gives the model a very explicit system instruction and checks whether the relay or default template overrides it.

Latency variance

Caution

Stable latency is consistent with one upstream; high variance may indicate queueing, multi-routing, or silent model switching.

Evidence summary

Instruction conflict

Instruction conflict found high-risk signals.
