 - Never apply an SSE event whose `session_id` differs from the bound lease. A later Local/Remote re-evaluation applies only to a later request.
 - Append `assistant.delta` text deterministically, then replace it with the authoritative `assistant.completed.content` response when present.
 - Report HTTP, I/O, or malformed-SSE failure only against the route/session lease that owned the failed call; an upstream `error` event fails the session without invalidating the route.
- Decode tool lifecycle/progress only when `tool_progress_events` is advertised; B4 does not render or persist those structured payloads.
+- Decode and render tool lifecycle/progress only when `tool_progress_events` is advertised. Treat event payload fields defensively, retain large output outside bounded display windows, and persist only client presentation state such as expansion.
+- Do not expose artifact share/save actions until an upstream artifact handoff capability and URI/download contract are advertised; the current direct gateway contract has neither.
