LOWPerplexity-User allowed
robots.txt permits Perplexity-User (Perplexity's live user-initiated fetcher) at the site root. Explicitly allowing Perplexity-User removes ambiguity about whether Perplexity can fetch pages live during user actions.
What this check looks for
Perplexity-User is the user-agent Perplexity uses for live fetches in response to user actions. Live user-initiated behavior can differ from index-crawler behavior, so this check is advisory. A well-configured store still allows Perplexity-User explicitly so the policy is unambiguous.

The spec it's pinned to
Perplexity bots — Perplexity-User
Perplexity's bots documentation lists Perplexity-User as the user-agent for live user-initiated fetches. Allowing it makes the policy explicit even when the fetch is user-driven.
