# K1 Chatend downstream test owner 0.2.0
`kcode-k1-chat-chatend-testkit` 0.2.0 owns the nine downstream public-API conformance tests removed from `kcode-k1-chat-chatend` 0.8.1. They preserve the 0.8.0 contract coverage against the exact `kcode-k1-chat-chatend = "=0.8.1"` dependency. Historical 0.1.0 is the prior Chatend 0.7.0 test line.
The tests cover empty `Agent Response` values at call-wave and Done boundaries, promised response IDs in the presence of arrivals, mixed provider ordering and tool dispatch selection, transactional rejection of a premature flush, marker-only boundary flushes, arrivals ordered after the Done response, idle recovery, and correlated tool messages and results.
This package has no runtime API. It is a concrete development-only test owner and does not define a reusable fixture framework, provider behavior, persistence, migration, deployment, or adoption.
