ADR-0002: Use CLI and browser-based application adapters

Status: Accepted

Context

BHTune needs both headless execution for scripts and an interactive operator interface. The public interface is a CLI and a browser GUI, both backed by the same tuning engine and run history, as described in the project introduction.

Decision

The supported application adapters are the bhtune CLI and a React SPA served by bhtune-server. The server exposes the HTTP API and serves the built browser interface; a native desktop shell is not part of this architecture.

Consequences

The browser interface uses the server's HTTP and SSE contracts, while the CLI can run without the server. Release builds package the browser assets with bhtune-server, keeping the web interface independent of a separate Node.js or static-file service on the target host.
