1//! Bridge between WASM plugins and the Channel trait.
2//!
3//! **Status:** Placeholder — `send` and `listen` are not yet wired to the
4//! Extism runtime.  Channel plugin support is a Phase 3 (v0.9.0) deliverable
5//! per the [Intentional Architecture RFC](https://github.com/zeroclaw-labs/zeroclaw/wiki/14.1-Intentional-Architecture).
6//! See `wasm_tool.rs` and `runtime.rs` for the working tool plugin bridge.
