The shift away from reading the flags directly at some call sites suggests those particular checks are being replaced by more targeted logic.\n\n- Flag `tengu_gorse_plover`: Off in both readings (read for one account on one subscription tier against v2.1.275; this account: off, anonymous baseline: off, compiled default: not a boolean we can read) 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: Gates\n- Tier: Nothing to try yet\n- Useful: 1\/5\n- Signal: 2\/5\n- Present in the build but not switched on"}
