matilda-core: modelo declarativo (Host, Container, VHost, Inventory). matilda-config: renderiza Container→docker-compose/docker run y VHost→bloque server nginx (con TLS + redirección :80→:443). matilda-plan: reconciliación pura actual→deseado con acciones ordenadas por dependencia (contenedores antes que vhosts, removes en orden inverso). Demo CLI en apps/matilda. 29 tests. Funciones puras, cero Docker/SSH/disco. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

//! `matilda` — demostración de administración de servidores.

|
|
//! Declara un inventario *deseado*, renderiza su `docker-compose.yml` y
|
|
//! su configuración nginx, y luego calcula el *plan* que lleva un
|
|
//! servidor desde un estado actual distinto hasta el deseado.
|
|
//!
|
|
//! Smoke test legible del módulo: `cargo run -p matilda`.
