// Yarn constraints: mechanize the package rules from AGENTS.md.
// Run with `yarn constraints`; CI fails on violations.
//
// 1. Every package is private (nothing publishes from this repo yet).
// 2. Harness packages (@deepseek-ai/dsh-*) declare `cordis` as BOTH a
//    peerDependency and a devDependency (upstream Cordis convention).
// 3. Harness packages are versioned 0.0.1 (bumped together, later via tooling).
// 4. Vendored packages keep their upstream versions — constraints don't touch
//    them beyond privacy.
// 5. All packages are ESM (`"type": "module"`) — except vendored packages
//    whose upstream isn't (schemastery ships dual cjs/mjs without type).
