Project Phoenix

Open-Core Standards For Grounded Domain Systems

Built on ideas and patterns from tau-bench (Sierra Research, MIT License)

Purpose

Project Phoenix publishes principles, standards, and white papers for building grounded domain systems that are inspectable, testable, and useful in practice.

It is not a generic chatbot layer. It is a framework for disciplined domain interfaces, deterministic validation, and carefully bounded agent use.

What Is Public Here

Open core: -> principles -> validation standards -> architecture notes -> white papers Private consulting layer: -> client pairing logic -> adaptation heuristics -> live operating playbooks

Why This Exists

Determinism

Push real execution and validation into explicit domain logic instead of relying only on prompt behavior.

Auditability

Make claims, artifacts, and trust boundaries inspectable rather than implicit.

Useful Standards

Provide patterns other people can adapt without needing to copy the full consulting process.
