Before this change, the check counted it as on unless the server set it to false. It now goes through a shared check that also counts it as on in two more cases:\n\n- when there is no way to read server settings at all\n\n- when reading the setting fails with an error\n\n**Why**\n\nThe switch is on unless the server explicitly turns it off, and that now holds even when settings cannot be read. Many parts of Claude Code consult it, so whatever it controls is in effect for anyone the server has not switched off.\n\n- Flag `tengu_foamy_spring`: Not enough to say (read for one account on one subscription tier against v2.1.309; this account: no value returned, anonymous baseline: no value returned, 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: Internals\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
