//! # IdeA — Domain layer
//!
//! The **pure** hexagonal core (ARCHITECTURE.md §1.4, §3, §4, §7). It contains:
//!
//! - **Entities & value objects** with invariants enforced by validating
//!   constructors (`new`/`try_new` returning `Result`),
//! - the **pure layout logic** (`split`/`merge`/`resize`/`move` as immutable
//!   `&LayoutTree -> Result<LayoutTree, LayoutError>` functions),
//! - **ports** (traits) the infrastructure implements,
//! - **domain events** and **errors**.
//!
//! ## Dependency rule
//!
//! This crate depends on **no I/O**: no `tokio`, no `std::fs`, no
//! `std::process`, no `git2`/`portable-pty`/`russh`. The only third-party
//! dependencies are `uuid`, `serde` (allowed solely to derive (de)serialisation
//! of *persisted* domain types — a metier format constraint, not I/O),
//! `thiserror`, and `async-trait`.
//!
//! ## Async strategy for ports
//!
//! I/O-touching ports (`PtyPort`, `FileSystem`, `ProcessSpawner`, `RemoteHost`,
//! the stores, `GitPort`) are `#[async_trait]`. They are injected as
//! `Arc<dyn Port>` trait objects at the composition root, which native
//! `async fn`-in-trait does not yet support dyn-compatibly without boxing;
//! `async_trait` boxes the returned future and keeps the ports object-safe.
//! Non-blocking ports (`Clock`, `IdGenerator`, `EventBus`, `AgentRuntime`)
//! remain plain synchronous traits. See [`ports`] for details.
