1//! The integrations service: a workspace's connections to systems outside
2//! g1t, and everything that crosses between them. See
3//! `g1t_contracts::integrations` for what each connection does and the
4//! methods and their arguments.
5//!
6//! Secrets are sealed at rest and never returned. A request an outside
7//! system sends is checked against the connection's signing secret,
8//! answered at once, and acted on afterwards, so a slow step never makes
9//! the sender give up and send it again.
