# K1 Chatend downstream conformance testkit 0.1.0
`kcode-k1-chat-chatend-testkit` is the concrete downstream conformance owner for `kcode-k1-chat-chatend` 0.7.0.
Call `assert_chatend_conformance` from a test to exercise correlated Tool Call, Tool Message, and Tool Result v1/v2 lifecycles; ordering and BoxID rules; fail-closed recognized metadata; inert unknown conventions; and cold recovery.
The assertion panics on a contract violation. This package exposes no generic fixture framework, protocol abstraction, provider behavior, persistence, deployment, or mutation of the tested dependency.
