Tamper-evident, stranger-verifiable receipts for LLM cost-savings — anyone can recompute your caching/routing savings math offline, no trust in your dashboard required. Pure stdlib, zero-dependency.
Helix gives you agents that actually behave in production: hard budget limits, semantic caching that cuts API costs by 40-70%, persistent memory, multi-agent teams, YAML-based task pipelines, and a 5-scorer eval suite.
