Struct ParamCtx 

pub struct ParamCtx<'a> { /* private fields */ }

What a built-in needs to resolve its parameters from inside an arena scope.

The sync built-ins (map, parse_*, publish_*, validation) run against an ArenaContext that earlier tasks in the same stretch already populated, and hold no TaskContext. Bundling the three pieces keeps their signatures to one extra argument, and keeps every parameter resolving against the same context view the task’s own logic sees — including mutations an earlier mapping in the same task made.
