//! # Brain Observability Bus
//!
//! Single source of truth for everything the user might want to see Brain do.
//!
//! - [`BrainEvent`] formalises every consequential moment in the signal lifecycle
//! (received, classified, routed, executed, audited, budget-crossed, etc.).
//! - [`Observer`] is the trait every consequential code path publishes through.
//! - [`BroadcastObserver`] is the default in-process fanout implementation.
//! - [`Redactor`] scrubs vault-marked secrets from any event payload before publication.
//!
//! The crate is intentionally self-contained — it owns no I/O or persistence;
//! wiring into `crates/signal` and `crates/audit` happens at the processor seam.
