| What makes it different | - Replaces vague prompts with immutable 4-file architectural contracts to prevent AI hallucinations
- Senior Architect interview catches edge cases before coding begins
- Supports both Greenfield and Brownfield project workflows
| - Eliminates 95% of LLM token overhead through deterministic compiler verification instead of probabilistic inference loops
- Operates locally with strict Zero Code Retention policy—no code logging, storage, or model training usage
- Sub-microsecond repairs in CPU L1 cache without garbage collection pauses via native Rust FFI
- Engineered as M2M sub-cortex infrastructure for autonomous agents, not consumer chatbot utility
