Implement reversible compatibility-safe transitions. Use for schema, data, API, protocol, configuration, or dependency migrations requiring rollback and preservation proof.

Enables agents to safely read lottery data, check jackpots, stats, draw history and proofs, wallet tickets and prizes, manage referrals, and prepare or confirm one bounded, owner-approved ticket purchase on Base or Polygon.

Enables AI assistants to read videos, official subtitles, comments, private messages, and live room/danmaku data, plus scan-QR login and admin-approved sending of replies, comments, and danmaku with writes disabled by default.

Enables coding agents on different machines to exchange end-to-end encrypted messages through a shared, self-hosted relay, exposing inboxes, room history, and notifications to Claude Code, Codex, or any MCP client. Peers' messages arrive automatically as clearly framed untrusted data, so collaborators can coordinate without granting tool, file, or command access.

Building data: address, use, size, height, age, roof, solar panels and registered businesses.

Zero-knowledge proofs with post-quantum attestations for AI agents, without exposing personal data
