-Live mode uses the same locked stack but skips pgTAP and the fake-provider specs. It runs `e2e/live/` on desktop Chromium against real OpenRouter, Jev, and Exa. Imported web pages are fetched live too. The fake provider becomes a recording proxy. It forwards every chat call to OpenRouter with the model pinned to `LIVE_MODEL` (default `z-ai/glm-5.3-flash`; CI reads the `LIVE_MODEL` repository variable), passes Jev decisions through unchanged, and refuses calls past `MAX_UPSTREAM_CALLS` (200). The default is inexpensive and broadly hosted, so requests can use OpenRouter's balanced provider routing instead of depending on one endpoint.
+Live mode uses the same locked stack but skips pgTAP and the fake-provider specs. It runs `e2e/live/` on desktop Chromium against real OpenRouter, Jev, and Exa. Imported web pages are fetched live too. The fake provider becomes a recording proxy. It forwards every chat call to OpenRouter with the model pinned to `LIVE_MODEL` (default `meta/muse-spark-1.3-contributor`; CI reads the `LIVE_MODEL` repository variable, which is unset), passes Jev decisions through unchanged, and refuses calls past `MAX_UPSTREAM_CALLS` (200). The default is the cheapest model that supports every request parameter the app sends, including `response_format` and reasoning effort. It is test-only and not in the app catalog, so users cannot pick it. Meta is its only provider, so an outage there fails the gate instead of failing over.
 
 The specs cover web-researched case generation, verified Factoids citations, Ask with web search, URL import, streamed Ask, Attack, Brainstorm, a judged sparring round, and Crossfire with live Jev signals. Outputs vary, so tests assert structure rather than text:
