 The framework `ctx` members and events every plugin sees beyond the harness tier — pinned vendor source ([vendoring policy](../../vendor/README.md)), summarized tersely so the harness pages stay focused on repository-owned vocabulary. Detailed Context, Fiber, Registry, and Service APIs are generated in [context.md](context.md), [fiber.md](fiber.md), [registry.md](registry.md), and [service.md](service.md); the event-dispatch methods in [events.md](events.md).
