Defined in:

Overview

Categorises a loaded plugin set by which per-call contribution paths each plugin actually implements, so the engine’s per-dispatch ‘collect_plugin_contributions` can iterate only the relevant plugins instead of calling into every plugin on every call site (a top hotspot on plugin-heavy projects — GitLab’s 11 plugins, of which only 2 implement any per-call path). Built once per Registry; the receiver-class ancestry match for ‘dynamic_return` still happens per-dispatch inside `Plugin::Base#dynamic_return_type`, so this only prunes plugins that structurally cannot contribute, preserving the exact contribution order and result.
