Claude Code spawns that runner with neither env nor cwd, so it could never read AI_BALANCER_ENABLED, and a helper that returns nothing renders as 'apiKeyHelper failed: did not return a value' on every launch. The balancer route instead exports ANTHROPIC_API_KEY into CLAUDE_ENV_FILE from the ai-balancer-proxy-start SessionStart hook, which DOES receive the env and so can gate on the flag. Nothing persists in settings, so the claude.ai login is the default and needs no undo.",

Kept in lockstep by agent/settings-env-matches-fleet-env.mts, so a knob added there fails this file until it is added here too.",
