Anthropic's January 2026 constitution refresh introduced a 4-tier priority hierarchy (safety → ethics → compliance → helpfulness) that fine-tuning cannot override. We translate the research paper into a practical alignment recipe any team can apply to GPT-4o, Claude, or Llama.

Endpointing decides the exact moment to send the transcript to the LLM. VAD-only is naive; semantic endpointing uses context. We compare both, with model-based turn detection benchmarks for 2026.
