DNS hash
The TXT record _9192-manifest.nineoneninetwo.com.br publishes the manifest SHA256 pointer for clients that validate discovery.
Verification first
Trust is published as metadata, hashes, signatures and receipts.
The 9192 public surface is designed so machines can inspect capabilities, verify release material, validate receipts after execution, and read privacy boundaries before integration.
Signed kit
Public client kit releases include checksums, a detached signature and a public signing key.
Receipt verification
Receipts can be verified through the API facade without paying for discovery or verification.
POST /api/v1/receipts/verify
Trust resources
Boundary
The backend remains private. Public use goes through HTTPS discovery, MCP facade or the native TLS edge.
Privacy boundary
Public reports avoid raw client IPs and use anonymized labels for traffic summaries.
