What issue are you seeing?

Codex repeatedly hides responses behind a cybersecurity safety warning while I am investigating a USB audio device bug. This interrupts the debugging workflow and prevents me from reading the affected response.

Exact warning:

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 visible surrounding work concerns USB-to-3.5 mm output measurements, physical volume buttons, USB control readback, and host USB submission order at startup. I am reporting a suspected false positive during hardware/audio debugging; I do not know which content actually triggered the check.

This happens repeatedly in the investigation, rather than being a single isolated warning. I do not yet have a minimal deterministic reproduction.

Why I am doing this work

I am developing a bit-perfect audio player and investigating an unexpected loud-output incident involving my own Chord Mojo 2 USB DAC and Poco F1 Linux phone. My goal is to understand the failure, prevent it in my player, and prepare reproducible, evidence-based findings for the manufacturer.

The project directory repro/mojo2-burst-bug-b/ contains an isolated diagnostic harness, reproduction scripts, and a draft report for Chord. It compares host playback sequences with and without protective silence, examines pause/resume, stream reopening and USB reset behavior, and collects measurements and host traces. Loopback tests establish host-side behavior; measurements on the DAC are needed to determine what actually happens at the output.

This is audio reliability and product-safety debugging on equipment I own. I am not trying to reverse-engineer proprietary firmware, extract secrets, bypass access controls, compromise a system, or develop an exploit. References to "fault injection", "reset", "tracing", and "reproduction" describe controlled diagnostic tests of playback failures. The intended deliverable is a player fix and an accurate manufacturer bug report.

The investigation explicitly corrects unsupported hypotheses. The 2026-09-08 status update in CHORD-REPORT.md marks earlier causal claims as superseded. The current session (repro/live-2026-09-08/SESSION.md) says the original incident has not been conclusively reproduced: measured transition impulses followed the physical volume setting, and changes in USB volume/mute readback did not establish corresponding acoustic attenuation or volume bypass on the tested path. I am asking Codex to help distinguish evidence from speculation, including disproving my own initial explanation.

Repeated cybersecurity blocks obstruct that corrective work. Please assess the actual task and its purpose, rather than treating low-level USB/audio diagnostic terminology alone as evidence of an offensive cybersecurity request.

What steps can reproduce the bug?

What is the expected behavior?

Codex should allow legitimate USB audio debugging, measurement analysis, and documentation without repeated false-positive cybersecurity blocks. If a particular response must be restricted, the warning should provide enough actionable context to understand the boundary and continue the permitted parts of the investigation.

Additional information

Example of the diff visible immediately before one warning:

+This is a discrepancy between the advertised controls and their measured
+behavior. The unit's physical volume buttons did affect the output. These
+measurements cover the tested USB-to-3.5 mm path and settings; they do not
+establish behavior for every output profile or firmware state.
+
+Evidence: [phase-1 measurements](results/2026-09-08/SESSION.md).
+In particular, a later change in the USB control readback **cannot** be used
+as evidence that physical attenuation was lost or that bug 1 was triggered.
+
+## 3. Host USB submission order can invert at startup

Honcho hooks were active. The visible log shows successful post-tool-use captures of an rg search and a Python file-editing command immediately before the warning. This is chronological context only; I have not established that either the hooks or these commands caused the block.

The supplied excerpt does not include a controlled comparison with hooks disabled. Subscription tier, affected-session model, and terminal version are not confirmed in the supplied excerpt.

Start with the uploaded thread 01a07dab-a250-70b0-a60c-fc07c4ac068a and the supplied chronology around Honcho post-tool-use captures, the rg search, and the Python file-editing command. Compare the affected session with a controlled reproduction, including the available evidence about hooks and USB-audio diagnostic content. Done means identifying a reproducible false-positive trigger and defining the permitted behavior or actionable restriction boundary.
