The result is cached as `threadsEnvOptIn`.\n\n- When that check passes, the `tengu_stellar_drift` and `tengu_humble_hammock` checks return true before any server gate is consulted. Their own variables, `CLAUDE_CODE_STELLAR_DRIFT` and `CLAUDE_CODE_HUMBLE_HAMMOCK`, still take priority, and both gates still fall back to false.\n\n- In another first-party check, the variable also skips the custom `ANTHROPIC_BASE_URL` check and the first-party endpoint check.\n\n- Tether live itself now uses the variable if set; otherwise false if a first-party condition fails; otherwise the gate `tengu_curious_tower`, which falls back to false. It no longer checks the base URL.\n\n- Under humble hammock, attachment building copies tool-input copies into messages, and declared-tool entries gain an optional `toolInputCopies` list. One extra condition depends on a function that always returns false.\n\n- A variant of the humble-hammock check that ignores the tether override is used for the tool-input-copies path and to register one SDK control-request schema.\n\nThe flag server returned on for `tengu_stellar_drift`, `tengu_humble_hammock` and `tengu_curious_tower`, both for this site's account and for the anonymous baseline, but no reading has been taken under this release yet.\n\n**Why**\n\nOne environment variable now acts as the switch for this set of features, including behind a custom base URL. If you set `CLAUDE_CODE_TETHER_LIVE=true`, expect all of them to turn on together.\n\n- Flag `tengu_stellar_drift`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.281; this account: on, anonymous baseline: on, 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_humble_hammock`: Off by default, switched on for this account (read for one account on one subscription tier against v2.1.281; this account: on, anonymous baseline: on, 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."}
