Expand description

The prelude names a macro body may not call, with the effect atom each performs.

Reading the tree’s own list rather than inventing one: these are the primitives whose scheme carries an atom in beck_core::prelude, plus http_fetch, whose net(host) atom is derived at the call site from the host it names (adr/0013) rather than written in its scheme.

Nothing here is reachable — the interpreter’s environment is a whitelist and none of these is on it — so this list buys a diagnostic rather than a control. It is the difference between “a macro may not read the clock” and “there is no name now”, and only the first is true.
