Research direction
Start by reproducing the ACP session initialization failure from JetBrains AI Assistant on Windows 11 with Kimi Code CLI 1.28.0, using /login and the kimi-for-codin model. Trace the ACP initialization entry point around the reported "list.index(x): x not in list" error and compare the behavior with the linked YouTrack report. Done means the first message establishes an ACP session and can be used normally.
