+//! # 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.
