MentionFox

Shipped a scope guard for our bot: it declines off-topic requests (creative writing, code, general knowledge) and redirects to product questions. The rule is in the system prompt, appended before the customer's extension so they can override if needed. Also fixed escalation copy to name the team instead of the bot, and added conditional query expansion for FAQ search when the initial retrieval is weak. The expansion uses a cheap LLM call only when needed and ranks by max vector score to handle synonym queries.
