Overview

Carries a message outward through the fragment hierarchy.

Nested fragments produce signals. Outer fragments consume them. Passing callbacks down the tree couples fragments tightly. Direct references make reuse difficult.

This command wraps a message for bubbling. Outer fragments intercept it and decide how to handle it. With the Router DSL, use observe or intercept. Without the Router, check for Command::Bubble manually and extract the message. Unhandled bubbles can be re-returned to continue propagation outward.

The runtime does not execute this command. Outer fragments handle it. Calling call raises an error.

message

The payload to propagate outward.
