feat(brahman-demo): bootstrap script reproducible — broker + producer + consumer + 4 explorers
Iter 22. Cierra el set de hoy: future-me (o cualquier nuevo collab)
levanta el escenario completo con un comando.
crates/apps/brahman-demo/ con 3 binarios:
- brahman-demo-broker: Server::bind standalone con Broker. Reemplaza
a ente-zero para demos (ente-zero es PID 1 con kernel surface,
child subreaper, bus, brain, audit — overkill).
- brahman-demo-producer: Card con flow.output[demo-stream:json].
- brahman-demo-consumer: Card con flow.input[demo-feed:json] —
mismo type → matchea con producer.
Env vars en los 3: BRAHMAN_INIT_SOCKET, BRAHMAN_BROKER_CONTEXT,
BRAHMAN_DEMO_LABEL/FLOW/TYPE, RUST_LOG.
scripts/bootstrap-demo.sh:
- Modes: all (default) / broker / only.
- Cleanup-safe: trap mata todos los PIDs spawneados (SIGTERM grace
+ SIGKILL fallback) y borra el socket.
- Espera al socket antes de spawnear (evita ENOENT en handshake).
- Logs separados por proceso bajo $BRAHMAN_DEMO_LOG_DIR.
Smoke end-to-end (sin DISPLAY): consumer recibe MatchEvent
{ Available, demo-feed ← demo-stream, via: Exact, pinned: false }
automáticamente cuando entra el producer. Match fluye por el push
channel del broker.

//! `brahman-demo-broker` — broker standalone para demos.
|
||||
//!
|
||||
//! ente-zero (PID 1) es el broker "real" pero pesa toneladas
|
||||
//! (kernel surface, child subreaper, bus, brain, audit, etc). Este
|
||||
//! binario sólo arma `brahman_handshake::Server::bind` con un broker
|
||||
//! configurado, escucha en el socket default, y corre forever.
|
||||
//!
|
||||
//! Suficiente para que el script de bootstrap (y los 4 explorers)
|
||||
//! tengan algo a qué conectarse sin necesitar el bootstrap PID 1
|
||||
//! completo.
|
||||
//!
|
||||
//! Variables de entorno respetadas:
|
||||
//! - `BRAHMAN_INIT_SOCKET` — path del Unix socket. Default: el
|
||||
//! resuelto por `brahman_handshake::transport::default_socket_path`.
|
||||
//! - `BRAHMAN_BROKER_CONTEXT` — context bias del broker (igual que
|
||||
//! ente-zero); afecta priority_contexts si las Cards lo declaran.
|
||||
//! - `RUST_LOG` — filtro de tracing (default `info`).
