Module set_vars 

Derived variables plugin (set-vars, featherbit-native): pull values out of the context — a path segment, a header, a query parameter, a JSON body field — optionally through a JSONPath and/or a regex capture, and store them in context.message so every downstream node can read them as $msg_<name> / {{message.<name>}}.

Always pass-through: wire success onward; the error port is never taken. Malformed regexes and JSONPaths reject the policy at compile time.

Structs

SetVarsPlugin

Evaluates every rule in order and writes each result into context.message[name] as a string. Later rules see earlier results ($msg_<name>), so rules can build on each other.
