It now checks whether that block is narration first and shows nothing if so. Only reachable with the sable-thrush gate on, which is off by default.\n\n**Details**\n\n- The call site also checks that the narration helper is present before using it, so builds without it behave as before.\n\n**Evidence**\n\n`isNarrationSummaryBlock`\n\n- Area: Thinking Display\n- Tier: Nothing to try yet\n- Useful: 2\/5\n- Signal: 3\/5\n- Present in the build but not switched on"}
