# parallel with lint/test/build/smoke/soak. It only blocks the final verify

  # ── 8b. Publish server.json to the official MCP Registry ──────
  # Runs after npm + PyPI so the registry can verify package ownership
  # (npm: `mcpName` field in package.json; PyPI: `mcp-name:` marker in
  # the package README). Authenticates with GitHub Actions OIDC — no
  # token, no interactive device flow. server.json's version is synced
  # from the just-published npm package so it always matches the release.
  #
  # Intentionally does NOT gate publish-final: the binary release is the
  # product, the registry entry is metadata. A registry-preview outage
  # must never block shipping. Re-run this job alone to retry — it does
  # not touch npm/PyPI, so retries are safe.
  #
  # It DOES depend on publish-final, which is the job that un-drafts the
  # release. Both used to need only publish-registries, so they raced: the
  # registry validates every package URL it is given by fetching it, and a
  # DRAFT release's assets are not publicly readable. In v0.10.3 the registry
  # ran 5s before the un-draft and was told its own .mcpb URL was a 404:
  #   MCPB package '...codebase-memory-mcp-darwin-amd64.mcpb' is not publicly
  #   accessible (status: 404)
  # The same URL served 200 once the release went public, and the job passed on
  # a plain re-run. Depending on publish-final keeps the documented intent
  # exactly — the registry still cannot block the release, it just runs after
  # the assets it validates actually exist to the outside world.
