It now reads a remote switch, `tengu_twinkling_hoare`, directly. That switch falls back to off when the server sends nothing.\n\n**Why**\n\nIt is not yet known what this check controls, so there is no visible effect to describe.\n\n- Flag `tengu_twinkling_hoare`: Not enough to say (read for one account on one subscription tier against v2.1.288; this account: no value returned, anonymous baseline: no value returned, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: Internals\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
