bombay — a typed behavior runtime.

The behavior half is [behavior]'s pure algebra (depended on, never copied). Bombay Communication supplies the sole mailbox implementation. A behavior is driven sequentially while its environment supplies events and interprets effects. Runtime construction remains centralized in [System::spawn]. Consumers that may publish an endpoint only after initialization and its effects succeed use [System::activate].

Panic strategy

Actor task panics are normalized as [TaskOutcome::Panicked], and terminal retirement completes during unwinding. The runtime therefore requires panic = "unwind"; abort-mode programs cannot preserve these public lifecycle outcomes.
