Four guarantees baked into every build — the design philosophy behind the substrate, in language you can quote back to your stakeholders.
No black-box AI.
Every step, every prompt, every retry — captured + auditable. Open any past build months later, scrub through it like a recording, no re-spending tokens. Engineering review, post-mortem, and compliance audit all run from the same source of truth.
Spend like an adult.
Pre-flight cost estimate before a build starts, mid-build budget checks, monotonic-progress retries. When attempts stop converging, init8 aborts — your tokens go where they compound, not where they spin.
Trust is wired in, not bolted on.
Tiered validation T0–T3, sandboxed test runs, security scans, adversarial review, agent constitution checks — every build, every time. Shipping a feature that breaks an invariant is a build-time failure, not a Friday afternoon.
Your stack. Your keys. Your codebase.
Bring your own LLM keys (OpenRouter / Anthropic / Groq / Gemini / OpenAI). Swap providers in YAML. Greenfield (new product) or brownfield (your existing repo) — same agents, two entry paths. No lock-in, no rewrite tax.
