Problem: When a question about Proton products/features finds no results via Lumo's Proton documentation lookup, Lumo currently concludes the feature doesn't exist — sometimes confidently warning users it may be a scam. In my case, Lumo denied Proton Pass AI Access Tokens (a real, shipped feature announced May 2026) and suggested I'd encountered phishing, because the docs index hadn't caught up with the announcement. Live web search quickly corrected this, but only because it happened to be used.

Requested feature: When the Proton documentation tool returns no results for a product question, Lumo should automatically fall back to web search before answering, rather than treating "not in the index" as "doesn't exist." This matters for user trust: the assistant contradicting Proton's own documentation undermines confidence in using it for Proton questions at all.
