The references that + * do resolve land on a same-named Function, cross-file included -- `USAGE + * lib/decl_type.ex -> Function type_target @lib/remote_type.ex`, and the + * @typep and @opaque equivalents. A Function standing in for a Type is the + * pollution rather than a record of it, so nothing correct is lost here. + * + * callback, macrocallback. The declared name IS a function name, so it + * resolves onto an implementation elsewhere in the corpus: pristine yields + * `CALLS lib/decl_callback.ex -> Function callback_fun @lib/impl_callback.ex` + * and the @macrocallback equivalent, both cross-file, and this build yields + * neither. That edge does point at a real Behaviour-to-Impl relationship, and + * nothing replaces it -- `@behaviour MyBehaviour` mints no edge of its own, + * so after this change nothing in the graph links a behaviour to its + * implementations. It is deleted anyway because it is name resolution and not + * a behaviour model: on a fixture with one @callback and three same-named + * `handle_it/1` defs, the single edge landed on the one module that + * implements nothing, leaving both real implementors at fan_in 0. Recording + * that relationship correctly means minting it from `@behaviour`, which is a + * separate change and not a reason to keep an arbitrary edge. + * + * The other accepted cost: `unquote(...)` inside a typespec does execute at + * compile time, so `@type t :: unquote(build_type())` loses its genuine + * `build_type` call edge along with the phantoms. + * + * Only this family is skipped.
