This replaces an earlier version of the same function that actually executed the tool call directly. The overall attestation mode (whether checks merely observe or actually enforce) depends on the `tengu_vast_tulip` setting, and the whole check only runs at all if a separate condition gated by `tengu_breezy_fairy` returns true.\n\n**Why**\n\nThis restructures how Claude Code evaluates whether a tool's host meets an attestation floor, separating the policy decision from tool execution, though whether this behaves as observe-only or enforcing depends on server-controlled settings not disclosed here.\n\n- Flag `tengu_breezy_fairy`: Off in both readings (read for one account on one subscription tier against v2.1.277; this account: off, anonymous baseline: off, 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- Flag `tengu_vast_tulip`: Off in both readings (read for one account on one subscription tier against v2.1.277; this account: off, anonymous baseline: off, 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: Tool Attestation\n- Names: `tengu_vast_tulip`, `tengu_breezy_fairy`\n- Tier: Nothing to try yet\n- Useful: 3\/5\n- Signal: 4\/5\n- Present in the build but not switched on"}
