yog: the standalone server for litany loops — the world, the balls and the conversations, behind one wire
Documentation
//! Shared harness + the construction / enumeration / accessor tests for the
//! multi-workspace [`AppModel`] (§15 Y11). The tick/sweep machinery is in
//! `derive`.
//!
//! What a seat is *looking at* is no longer here to test (bl-7942): the focus,
//! its startup derivation and the optimistic echo folded over it were the
//! window's, and a server holds none of them (REMOTE §7).
