CHW-1402 BillyNotConfigured

Billy is not configured on this instance; ask an operator to set OPENROUTER_API_KEY to enable the AI assistant

Default message: Billy is not configured on this instance; ask an operator to set OPENROUTER_API_KEY to enable the AI assistant
HTTP status: 503 (server)

Problem. A Billy AI assistant endpoint returned 503 even though the caller’s plan includes billy. Cause. The operator has not set OPENROUTER_API_KEY on the process, so there is no upstream model to proxy chat to. Fix. Ask the operator to set OPENROUTER_API_KEY and restart the server. The UI parses the message to differentiate this from a plan-gate refusal. HTTP 503.
