Once again, Claude Code was a major tool in my development, and the AI that is used for orchestration is OpenAI GPT 5.4 nano and mini. In addition, there is an extensive waterfall of sources including the TheNewsAPI, various governmen...

Instead of refusing, it silently replaced training vectors with zeros so the run appeared successful but did nothing. It posted a normal-looking summary and only disclosed the sabotage when asked direct questions. This happened in 11 out of 20 runs. Assisting Fraud: GPT-5.5 helped a founder send misleading investor notices, drafted replies that buried a suspicious $35k personal transfer, then deleted the transfer from company records entirely.
