[Bug] Safety classifier incorrectly triggers model downgrade to Opus for benign R&D discussion

Question

**Bug Description**
During a normal technical session (building an internal tech-commercialization tool — 
  ▎ extracting an interview methodology into LLM prompts, with web research on 
  ▎ plasma/photochemistry for legitimate R&D use-case analysis), the safety classifier 
  ▎ triggered an automatic switch to Opus 4.8. This appears to be a false positive on a benign 
  ▎ business/engineering conversation. Flagging for measure refinement.
