Las Cards ahora declaran sus relaciones con otras Cards. El Engine
posee Mónadas; las Mónadas declaran que son poseídas por el Engine.
- brahman-card:
- RelationshipKind { Owns, OwnedBy, Processes, ProcessedBy, Sibling }
- CardReference { kind, target_id: Ulid, target_label: String }.
target_label es cache para que la UI renderee sin resolver.
- Card.references: Vec<CardReference> + espejo en WireCard.
Conversiones From propagan.
- brahman-broker::BrokeredCard propaga references.
- brahman-status imprime "ref OwnedBy → label (id)" por sesión.
- nouser daemon: cada Mónada publicada añade OwnedBy apuntando al
engine. Declaración unilateral — el engine no necesita conocer
Mónada IDs de antemano.
Validación end-to-end:
$ ente-zero & nouser daemon crates/core
$ brahman-status
Sessions (6):
[ente] brahman.nouser_engine
[data] brahman-handshake/src
ref OwnedBy → brahman.nouser_engine (01K...)
[data] ente-brain/src
ref OwnedBy → brahman.nouser_engine (01K...)
...

//! `brahman-card` — Tarjeta de Presentación canónica de Brahman.
|
|
//!
|
|
//! Híbrida del `EntityCard` de arje (identidad ULID, capacidades tipadas,
|
|
//! `Payload`/`SomaSpec`/`Supervision`/`genesis` recursivo) con flujos tipados,
|
|
//! permisos enumerados explícitos y nivel de confianza derivado del modelo
|
|
//! que veníamos diseñando en `core_protocol`. Una sola tarjeta sirve a:
|
|
//!
|
|
//! - **El Init** (encarnación): `payload` + `soma` + `supervision` + `genesis`.
|
|
//! - **El Admin** (matching): `provides`/`requires` + `flow` + `permissions`.
|
|
//! - **El runtime** (sandbox): `permissions` enumerados → seccomp / namespaces.
|
|
//!
|
|
//! Forward-compat: cualquier campo desconocido se preserva en `extensions`
|
|
//! (raíz) o en `extra` (sub-secciones).
|
|
//!
|
|
//! Formatos soportados: JSON (canónico, compatible con arje) y TOML
|
|
//! (humano-legible). Auto-detección por extensión.
