//! The harness shared by the integration tests: a synthetic Claude Code installation, a
//! stand-in for Anthropic, and the guard that keeps every test away from a real login.
//!
//! Every service name a test writes is derived from that test's own name, which Rust
//! already forbids two tests in a module from sharing.

// Compiled separately into every test binary that declares `mod common`, so a binary that
// does not use one of these helpers would otherwise warn about it.

/// Refuse a service name that this machine's Claude Code would actually read.
///
/// A slot hashed from a scratch directory is safe by construction and is exactly what the
/// round-trip tests need, so the family as a whole is not off limits — only the two names
/// that resolve to a real login here.
