// Koru Standard Library: the possession-shaped callable surface.
// Joined via `~part affordances` in runtime.kz; merged into the runtime

//
// SCOPE-AFFORDANCES - the callable surface, possession-shaped (HATEOAS rooms)
//
// `scope-vocabulary` is the static surface: everything the scope declares.
// This is the live half: what may be called GIVEN the resource types the
// caller holds. An event is callable now iff every discharge-kind phantom it
// consumes (`!open`) names a held type; events with no possession requirement
// are always callable. `held` is a comma-separated list of resource-type
// names (the `created_by_event` segments of the caller's live handles). The
// render uses the same signature spelling as scope-vocabulary, so the
// callable subset and the static vocabulary are the same bytes filtered.
//
// The projection is structural — it reads the scope's declared input fields
// and phantoms, never a rendered string — so the filter and the enforcement
// cannot drift (same contract as scope-manifest).
//
// @retain: scope_affordances_event is referenced from generated Zig code in
// bridge pipelines (std/bridge:affordances compiles to
// scope_affordances_event.handler).
