This site IS the registry (spec §25): the index lives at /registry/index.ptr, packages beside it — published by git push through the deploy chain. ptc vendor consults the index and fetches manifest + modules into vendor/; imports resolve local → vendor/ → stdlib. Before the push, ptc pack runs the publishing gate (since Sprint 50): strict manifest, fmt --check, a /// doc on every pub item, every test green — then it prints the exact index.ptr line to paste.
