They sit in the same lists as `CLAUDE_CODE_WITTY_DEWDROP` and `CLAUDE_CODE_SESSION_ORIGIN`. `CLAUDE_CODE_DEEP_TWILIGHT` appears in only one of those lists.\n\n**Why**\n\nThe names point to features that are present in this build but not described anywhere, so setting them has no documented effect.\n\n- Area: Environment Variables\n- Names: `CLAUDE_CODE_FIZZY_GROVE`, `CLAUDE_CODE_DEEP_TWILIGHT`, `CLAUDE_CODE_WITTY_DEWDROP`, `CLAUDE_CODE_SESSION_ORIGIN`\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
