Crate rux_script 

Rux script tier, milestone M8.

Wraps a rhai engine that holds the app’s live state (the script’s top-level let variables persist in a Scope) and evaluates {{ }} bindings, r-if/r-for expressions, and @tap handlers against it. Native capabilities are exposed under the host:: namespace via the builder.

This replaces the M5 signal reader and the M6 inline-expression evaluator with a real scripting language: named fn handlers, full expressions, and the compiled-Rust boundary (docs/04-architecture.md, script/host tiers).

Structs

Builder

Builds an Engine: register host functions, then build with the script. Host functions must be registered before the script runs, since the script may call them during initialization.

Engine

A live script engine: state in scope, script functions in funcs.

Functions

set_stderr_echo

Stop (or resume) mirroring warnings to stderr.

take_warnings

Take the expression failures raised since the last call, emptying the sink.
