How does the Etuki Universal FinOps Execution Compiler prevent 272K, 200K, 100K, and 256K context-cliff bill spikes?

Etuki enforces a two-tier soft-block routing architecture: Tier 1 intercepts prompts at 90% of hard vendor cliffs (244,800 tokens for OpenAI >272K, 180,000 for Grok/Gemini >=200K, 90,000 for Haiku >100K) and reroutes overflow to flat-window Claude Sonnet 5.5. Tier 2 takes precedence for Alibaba Qwen 3.7 Flash, keeping 32K-230.4K prompts on Qwen 3.7 Flash (0.96 CNY/1M) and rerouting >230,400 tokens (90% of 256K cliff) to Qwen 3.8 Flash (0-1M flat tier at 1.18 CNY/1M).
