Status

The native client supports unary task submission and observation, public task output, themes, viewport controls, run inspection and host logs. Headless mode uses the same client and fails closed on input/authentication requirements.

One-task interactive A2A composition is available. Streaming, approval attachment, context continuation and durable resume remain open. Full served parity and release performance are not established by focused tests. The Python implementation is removed, not a fallback. See the canonical requirements.

An explicit local ACP v1 path supports interactive text sessions and headless one-shot text through an internal Arbora child process. It advertises no host tools or permission grants. Its scripted and SDK transport checks are not proof of a released Arbora/AU pairing or durable history. These remain open under TUI-RUNTIME-R011.14 and the existing coding-session requirements.
