// What this repository says about itself must be true, and must be something the
// build toolchain can read.
//
// On 2026-04-21 a commit pointed repository/homepage/bugs at our Gitea instance
// ("migrate git dependencies to Gitea mirror"). Nothing else moved: origin is
// still GitHub, the published package still says GitHub, and
// git.pezkuwichain.io/pezkuwichain/phishing answers 500 — so every installer of
// @pezkuwi/phishing got dead links for its homepage and its bug tracker.
//
// It also broke `yarn build` from 2026-09-13, when the toolchain started reading
// the field. @pezkuwi/dev does this, and it is ours:
//
//     const repoPath = pkg.repository.url
//       .split('https://github.com/')[1]
//       .split('.git')[0];
//
// A URL from any other host makes [1] undefined and the build dies with
// "Cannot read properties of undefined (reading 'split')" — a message that names
// neither the field nor the file.
//
// So this check is also the tripwire for the migration that was started and left
// half-done: moving this repository to Gitea for real means fixing @pezkuwi/dev
// first, so that a toolchain built for a state that hosts its own git stops
// assuming github.com. Until that happens, this check turns the metadata red
// here rather than letting it fail as an unreadable stack trace, or ship as a
// dead link.
