Key Engineering Principles
Statistical Bounds over Binary Asserts
Ensure evaluation harnesses measure confidence distributions across diverse multi-turn test sets rather than brittle point equality checks.
Immutable Traceability & Provenance
Capture complete prompt templates, model versions, temperature parameters, and retrieved chunk hashes for all inference payloads.
Fail-Safe Fallbacks & Circuit Breakers
Enforce graceful degradation paths when latency spikes, model rate limits occur, or guardrails reject unsafe responses.
