lib.rs

//! Composition root: the single place that knows which modules exist.
//!
//! Both the API and the worker assemble their module wiring from this crate, so
//! a module is registered here once rather than in scattered per-app edits.
//!
//! A module's contributions are split by how they are consumed:
//! - [`modules`]: context-bound bindings (runtime functions + event handlers)
//!   and runtime config (API + worker), demo-default for context-local callers.
//! - [`modules_for_config`] / [`load_modules`]: config-aware module loaders that
//!   honor profile entry lists and configured remote sources for runtime apps.
//! - [`module_manifests`]: context-free manifest data (no [`AppContext`]) for
//!   read-only / `OpenAPI` paths, with profile-aware variants for runtime use.
//! - [`merge_linked_http`]: context-free HTTP routes and their OpenAPI docs
//!   (API only), assembled without a live [`AppContext`].
//! - [`story_display_descriptors`]: console display metadata, sourced from the
//!   context-free [`module_manifests`].
//!
//! When adding a module, register it in the appropriate profile entry lists and
//! expose its config-aware loader contributions from this crate.
