#!/usr/bin/env node
// Assemble a milestone release's notes, per server, and optionally create the
// draft GitHub Release (#5056) —
// `npm run release:notes -- --milestone vX.Y.Z --merge-sha <sha> --merge-branch <b> --ledger-url <u> [...]`.
// It replaces the shell recipe the release skill's step 5a carried, and is
// modeled on the MCP Inspector's helper (modelcontextprotocol/inspector#2550),
// adapted to a repository that publishes seven packages at seven versions.
//
// A reader of a release wants to know what changed in the server they use, so
// the notes are laid out per PACKAGE rather than as one flat list:
//
//   ## Packages                      every package, its version, and whether
//                                    this release publishes it (registry check)
//   ## <package> <version>           one per PUBLISHED package, with its
//     ### What's Changed             PRs
//   ## Repository                    every PR left over (CI, docs, skills, a
//                                    server whose version did not change), so
//                                    no PR in the generated list is dropped
//   ## New Contributors / Full Changelog   GitHub's own trailer, verbatim
//   Release ledger: [<branch>](<url>)
//   ## Known issues                  only when passed in: a maintainer's call
//   ## Thanks for helping us improve one release-wide list of the community
//                                    members whose issues the PRs close, laid
//                                    out as the Inspector's release notes are
//
// The PR list is GitHub's generated one (`releases/generate-notes`, what the
// UI's button uses) from the latest PUBLISHED Release to the merge commit. A
// PR is bucketed by the files it changes: `src/<dir>/` is that directory's
// package. Thanks credits each closed issue's author; maintainers
// (admin/maintain/write), bots and deleted accounts are never credited.
// GitHub adds everyone `@`-mentioned in a release body to its Contributors
// strip, so that section is what puts the reporters there.
//
// FAIL FAST. Every `gh` call and registry request is checked and a failure
// throws before anything is created: a permission lookup that errors must
// never read as "community" (that could credit a maintainer), a rate-limited
// lookup must never drop a PR or a reporter, and a registry that does not
// answer says nothing about what this release publishes. A permission value or
// a generated-notes line outside the known set throws for the same reason.
//
// The default run is a PREVIEW that prints the notes and creates nothing.
// `--draft` creates a draft Release at the merge SHA under the milestone tag.
// There is deliberately no `--publish`: publishing starts `release.yml`, so it
// stays a maintainer's act on the draft (the release skill, step 5b).
