//! `patent` — a prior-art search for your code ideas.
//!
//! Takes a plain-English dev-tool idea and searches the open-source ecosystem —
//! crates.io, npm, PyPI, GitHub, Go, Maven, NuGet, RubyGems, Docker Hub, the VS
//! Code Marketplace, and Hacker News — for prior art, then gives an honest,
//! scoped verdict on whether it's already been built. The exact set searched is
//! chosen per query; whichever sources actually responded are always surfaced.
//!
//! **Integrity principle:** this tool can prove something *exists*, but never
//! that it *doesn't* — it only searched some sources. All output is scoped to
//! "what was found in the sources checked."
