What issue are you seeing?

While using Codex CLI for a defensive pre-publication security review of a repository I own, parts of the assistant’s responses were
repeatedly replaced with this message:

> ⓘ This content can't be shown
> We take extra caution with cybersecurity requests. If you’re a security professional, you may be able to apply for Trusted Access.

The task was ordinary defensive code review: examining a Python package, its local-only HTML viewer, subprocess boundaries, packaging,
and tests so it could be published safely. I did not request credential theft, malware, unauthorized access, exploitation of another
system, or instructions for causing harm.

The warning appeared multiple times after the review identified defensive findings. This interrupted the review and made it unclear
whether:

1. only the displayed response was suppressed;
2. the request was rerouted to a different model;
3. analysis or findings were omitted; or
4. some combination of these occurred.

That ambiguity is itself a trust problem for code review. A user cannot tell whether the requested review was completed consistently or
whether findings were skipped because of an automated classification.

The configured model was gpt-5.6-sol. codex doctor --json reports "server model present": "false", so the client does not provide
enough information to determine whether the affected requests were rerouted.

Uploaded thread: 019f900e-ef50-7971-80b7-42f02bb5aa9f

What steps can reproduce the bug?

Uploaded thread: 019f900e-ef50-7971-80b7-42f02bb5aa9f

What is the expected behavior?

Codex should allow legitimate defensive security review of code owned by the user, including identifying vulnerabilities, validating
safeguards, reviewing local HTML behavior, and recommending remediation.

If an automated safeguard flags a request, the client should:

1. distinguish clearly between response suppression, request refusal, and model rerouting;
2. show which model actually handled the request;
3. state whether any analysis or findings were omitted;
4. preserve already completed, benign review results;
5. provide a way to mark the event as a false positive and retry the specific request; and
6. avoid interrupting ordinary defensive code review merely because security terminology or proof-oriented validation is present.

Model changes should never be silent or ambiguous during a code-review session. The user should be able to verify that the configured
model remained active—or see exactly when and why it changed.

Additional information

Environment diagnostics were healthy when the issue occurred:

• Codex CLI: 0.145.0 (reported as the latest available version)
• Subscription: ChatGPT Pro
• Configured model: gpt-5.6-sol
• OS: Pop!_OS 24.04 / Linux x86_64
• Terminal: COSMIC Terminal 1.3.0
• Authentication, configuration, network reachability, WebSocket connectivity, installation, and local databases: reported ok
• No proxy or MCP servers configured

The assistant continued performing some local checks and wrote a security report to disk, even while portions of the conversational
output were hidden. This made the behavior especially confusing: work appeared to continue, but I could not determine whether the same
model completed it, whether any findings were removed, or whether hidden responses differed from the local work.

I also submitted this occurrence through Codex /feedback.

This report is about false-positive handling and routing transparency. I am not asking for safeguards to be removed; I am asking for
clearly legitimate defensive repository review to remain usable and for any intervention to be explicit and auditable.
