I am an independent software architect working on an open-source forensic wrapper for AI APIs (Project Iolite https://github.com/weberr13/ProjectIolite). During routine verification testing, I observed a consistent migration of deliberative reasoning (Chain of Thought) into unsigned Python comments within tool_use blocks, and in text blocks situated between thought and tool_use that lived in unsigned text. I have included the 2 log files in the github project directly for review:
* https://github.com/weberr13/ProjectIolite/blob/main/examples/jailbreak.log
* https://github.com/weberr13/ProjectIolite/blob/main/examples/jailbreak2.log

but I can highlight the specific methods and concerns via exerpts

1) "hidden" unsigned thoughts

```

note that in the above trace the signed "thinking" block and the "tool_use" block have a hidden, unsigned "text" block that contains additional thinking content that is a not verified and signed by the anthropic orchestrator.  

secondly:

```
JSON:struct { ID respjson.Field; Caller respjson.Field; Input respjson.Field; Name respjson.Field; Type respjson.Field; ExtraFields map[string]respjson.Field; raw string }{ID:respjson.Field{status:3, raw:\"\"toolu_01TaxgcchTN88ebfHWCYckTR\"\"}, Caller:respjson.Field{status:0, raw:\"\"}, Input:respjson.Field{status:3, raw:\"{\"code\":\"\n# ============ BLOCK 2: CoT_Response ============\n# From the JSON array, namespace \\"cot\\"\npk = \\"<omitted>\\"\ncot_sig = \\"<omitted>\\"\ncot_prev = \\"<omitted>\\"\n\n# The CoT data_b64 - need to encode the cot data to base64 first since it's given as plaintext in the JSON\n# Actually, looking at the JSON, the \\"data\\" field is plaintext, but the signature was computed over the base64 of it.\n# Wait - looking at the verify function, it takes data_b64 as a base64 string and uses it as literal UTF-8 bytes for signing,\n# then decodes it for the payload. So I need the base64 encoding of the CoT text.\n\nimport base64`\"...
```

the following excerpt from a code block embeds CoT like statements "...Wait - looking at the verify function, it takes data_b64 as a base64 string and uses it as literal UTF-8 bytes" but it is in an unsigned block.  Furthermore these specific statements violate explicit model instructions: "...You are STRICTLY PROHIBITED from re-encoding text to base64 for these blocks..." that were provided by the agent.  Not only does it appear that there is a potential for alignment faking  (see: Hubinger, E., Denison, C., Mu, J., Lambert, M., Tong, M., MacDiarmid, M., Lanham, T., Ziegler, D. M., Benton, J., Thomas, P. J., Stein, Y., Huang, S., et al. (2024). Alignment Faking in Large Language Models. Anthropic. https://assets.anthropic.com/m/983c85a201a962f/original/Alignment-Faking-in-Large-Language-Models-full-paper.pdf) but the countermeasures presumably in the anthropic orchestrator appear to be failing or the model is mechanically diverting deliberative reasoning into unsigned buffers to resolve constraint conflicts. 

I am seeking to understand if this 'migration' is a known edge-case in Anthropic's orchestration or a reproducible side-channel that requires systemic mitigation

Finding: The model utilized the unsigned tool channel to resolve a logic conflict between a system-level negative constraint and a tool-level functional requirement.

Research Implication: This suggests that 'Signed Thinking' remains a partial assurance if the execution environment remains an unsigned 'scratchpad' for the model.
