State changed to planning.
Decision
Returned to planning because the current ticket is not concrete enough.
The purpose is specifically observation: Backend subscribes to a Runtime-owned WebSocket stream to receive Worker output and related runtime/worker events. It is not a command channel, not browser-facing, and not the path for sending user input.
Before this can be ready, define the event model and protocol boundary concretely:
- which Worker output events are streamed (text delta/final, reasoning visibility policy, tool call lifecycle, status, run started/completed/errored, usage, diagnostics);
- whether the stream is runtime-wide, worker-scoped, or both;
- event envelope shape, event id/cursor semantics, ordering, backlog, reconnect behavior, and unknown/expired cursor handling;
- relationship between streamed output and transcript projection/event log persistence;
- Backend client/proxy expectations and how Browser receives the projection without connecting directly to Runtime;
- what is deliberately excluded from the stream, such as raw provider trace or raw full session log.
Decision
Runtime WebSocket event stream は、新しい Worker output protocol を作らず crates/protocol の protocol::Event を Backend-facing observation payload として流す方針にする。Runtime WS は protocol::Event の variant allowlist / subset を定義せず、worker-scoped envelope に event id / cursor / worker id を付けて Worker event bus の protocol::Event を forward する。
Browser / Web UI は Runtime WS に直接接続しない。Backend が Runtime WS client になり、Browser-facing stream は Backend-owned projection layer を通す。この projection layer を、後続の Web 権限制御で observation allow/deny、thinking/tool output/diagnostic redaction、operation-capable command API forwarding allow/deny を差し込む境界にする。STJT では full auth model は実装せず、この seam を型と責務として作る。
