Two paths ended a streaming advance without a terminal `state`/`error` frame, leaving the SSE client stalled to the deadline with a stale held version -> its next action 409s: 1. advance_session published the terminal `state` frame outside the try/finally and unguarded. If the post-advance view projection (get_session_view -> read_graph) or the publish itself raised after a SUCCESSFUL advance, the exception escaped and no terminal frame was sent. Guard it and fall back to a terminal `error` frame. 2. submit_action_stream emitted a terminal `state` frame on settle only for `message`. `update_model` also settles synchronously while bumping the version, so it now emits one too -- otherwise the FE keeps the old version and 409s on its next action. Adds regression tests for both (projection-failure -> error frame; update_model -> state frame). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
