g1t/services/integrations/src/lib.rs
//! The integrations service: a workspace's connections to systems outside
//! g1t, and everything that crosses between them. See
//! `g1t_contracts::integrations` for what each connection does and the
//! methods and their arguments.
//!
//! Secrets are sealed at rest and never returned. A request an outside
//! system sends is checked against the connection's signing secret,
//! answered at once, and acted on afterwards, so a slow step never makes
//! the sender give up and send it again.
