The upper limit on a server-advised heartbeat interval was a flat 900000 ms; it is now effectively unbounded, still capped by the session token's lifetime.\n\n**Details**\n\n- Only applies when the caller advertises heartbeat probe support, which defaults to off; without it the ceiling stays 300000 ms.\n- The new ceiling is computed as the maximum 32-bit integer divided by one plus the jitter fraction.\n\n**Evidence**\n\n`cli_heartbeat_interval_updated`\n\n- Area: Remote Control\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 3\/5"}
