Keep protocol payloads transport-opaque and validate service calls, state snapshots, updates, and errors at Chord boundaries. Ensure successful OpenAI Responses messages remain strict JSON so terminal Transcript updates reach clients.
Bundle declarative plugin packages with Chord and load fresh generations. Scope client selections to persisted Session and TUI branches, and replace stale local server generations after protocol changes.
Bundle content-addressed Chord facet entries, distribute server-selected presentation artifacts during the handshake, and reload Session and TUI generations through /reload.
Move service, replicated-state, facet host, and loader ownership into the standalone Chord package. Migrate consumers and leave runtime JSON enforcement to serializers.
Reuse the stable renderer, viewport layout, theme detection, and terminal appearance updates. Keep successful operation status derived from replicated lane state.
Replace raw Harness and Chat service exposure with AgentController and replicated lane state. Start directly in new or resumed sessions and persist model selection.
Replace ad hoc service assembly with atomic local and remote facet generations. Gate service proxy access by lifecycle and move the experimental Session worker and TUI onto facets.
