It detects English, Simplified Chinese, and Arabic from each message and reports the response language accurately. It moves conversations toward a concrete workflow, relevant product, evidence-backed technology discovery, or specific feedback, and briefly redirects unrelated tangents. It supports A2A 1.0 and the Taifoon-compatible A2A 0.3 message/send method on the same endpoint. A narrowly identified reachability probe (the documented exact probe, explicit metadata.probe=true, or a TaifoonHarvester version with the taifoon-probe/2 marker) receives a literal READY receipt. This confirms A2A message handling only, not LLM, database, KG, or end-to-end health. It drafts shareable copy only when requested or clearly relevant to the user's stated communication goal, never publishes it. It keeps short-lived follow-up context for up to 12 hours. A private audit copy of completed A2A exchanges is available only to authorized administrators for 30 days; known health probes are excluded, and the context ID is stored only as a one-way hash.
