You are rebuilding the write path of a high-traffic URL shortener. Threat-intel lookups (Safe Browsing API, local blocklist replicas) currently run inline on link creation, pushing p99 to 800 ms and failing creation outright whenever a feed is degraded, so scanning has to move off the request path. Two read-path constraints remain: a short link must never issue an automatic redirect to a destination that has not been cleared, and the first fetch of a new link — usually a messaging-app preview crawler arriving within a second of creation — must return a usable page, because a non-2xx response gets cached as a broken link for 24 hours. Which design meets both?

The 8B's self-reported confidence has rank correlation 0.1 with correctness, ground-truth labels reach you weeks after a ticket is answered, the ticket mix shifts every month, and you can afford a 2% shadow sample. Which design do you ship?
