message-stream

Retired native-event drill-down — a terminal-free console is the TimelineChat conversation itself, with no second full-process view.

This feature is retired. A headless session's console is exactly the shared session-timeline/TimelineChat conversation on desktop and phone. The conversation is already the durable record a reader needs, so it exposes no full-process door, alternate native-event view, adapter capability, native-message REST/SSE routes, or second session-store transcript.

Harness-native stream output remains an adapter transport detail where a headless runtime needs it; SpexCode does not project those envelopes into a second user-facing record. Pane-backed adapters continue to render their live terminal. This node remains in the tree to make that retired boundary explicit rather than leaving old links or deleted-file anchors behind.
