  "description": "DNS Txt Chunk Join: DNS Txt Chunk Join joins quoted DNS TXT chunks into the logical record value from bounded caller-supplied values without an external provider. Call DNS Txt Chunk Join before treating quoted DNS TXT chunks as one logical record. Returns normalized web evidence, the computed finding, and an explicit pass or advisory status for DNS Txt Chunk Join as versioned deterministic JSON. Price: $0.001 USDC via x402 on Base. First-party, stateless, memory-only execution with no paid upstream, live RPC, web search, credentials, custody, signing, media generator, or input retention. Honest limit: Evaluates only caller-supplied metadata; it performs no DNS lookup, HTTP request, web search, credential use, or persistent storage. Advisory output only; the buyer owns authorization, payment policy, and production decisions.",
