How Harmonia uses it

YouTube supplies authorized source metadata and media context. Hacker News Algolia supplies public trend signals. Telegram offers an allow-listed operator surface. Google Calendar synchronization is explicit, and X publishing uses the official API behind digest-bound approval and idempotent execution.
