ChainAPI

Architecture

ChainAPI’s architecture is documented in doc/ChainAPI - Project Layout.md and PRD §8.

Key principles:

  • Engine boundary — libchainapi-engine has no Qt UI dependency. Mechanically enforced via CMake link guards, CI grep checks, and pImpl public headers.
  • Layered C++ — domain → application → infrastructure, dependencies pointing inward only.
  • Phase B option — the engine is constructable as an in-process library today and extractable to a separate process or rewritten in Rust later. Architectural guardrails make this a build-system change, not a rewrite.
