Workspace en 4 ejes (core/modules/apps/shared):
- core/: 24 crates de arje (Init systemd-compatible: ente-card, ente-zero,
ente-kernel, ente-bus, ente-cas, ente-soma, ente-wasm, ente-snapshot,
ente-brain, ente-echo, ente-policy-provider, + 12 crates *-compat)
- modules/semantic_dht/: 5 crates de minga (minga-core con AST/CAS/MST,
minga-p2p con libp2p Kad, minga-store, minga-vfs, minga-cli)
- modules/ui_engine/: 11 crates de yahweh (libs/{core,theme,bus,providers},
widgets/{tree,splitter,tabs,tiled,container_core,text_input})
- apps/: 5 crates de yahweh (file_explorer, database_explorer, text_viewer,
image_viewer, yahweh-shell)
- shared_wit/protocol.wit: handshake/lifecycle inicial
Cargo.toml unificado: thiserror bumped a 2 (transparente para arje), tokio
"full", paths intra-workspace de yahweh redirigidos a su nueva ubicación.
cargo check --workspace: 0 errores, 17 warnings (dead code preexistente).

//! `LayoutModel` — fuente de verdad mutable del árbol de layout.
|
|
//!
|
|
//! Distinguimos dos clases de cambio:
|
|
//!
|
|
//! - [`LayoutModelEvent::StructureChanged`]: cambios que requieren rebuild
|
|
//! del árbol de entidades (kind, children, params relevantes). Estos
|
|
//! también invocan `cx.notify()` para que los `cx.observe` (StatusPanel,
|
|
//! etc.) refresquen.
|
|
//! - [`LayoutModelEvent::FlexChanged`]: actualización de `flex` de un
|
|
//! nodo (típicamente proviene de un drag de divisor). NO requiere
|
|
//! rebuild — el SplitContainer ya tiene el flex aplicado en su Vec; solo
|
|
//! nos importa para persistir. Por eso no llamamos `cx.notify()`: solo
|
|
//! emitimos el evento, así los `cx.observe` (que rebuilden) se mantienen
|
|
//! silenciosos durante el drag.
|
|
//!
|
|
//! El `Persister` (ver `shell/persister.rs`) se subscribe vía
|
|
//! `cx.subscribe` y reacciona a los dos.
