how do I create one-to-one edge relation?

  tags: defineEnt({
    name: v.string(),
  }).edge("post"),

  posts: defineEnt({
    title: v.string(),
    body: v.string(),
  }).edge("tag"),

  tags: defineEnt({
    name: v.string(),
  }).edge("post"),

  posts: defineEnt({
    title: v.string(),
    body: v.string(),
  }).edge("tag"),

One post has one tag and one tag has one post. How do I create these records at the same time? Because one needs to exist before the other.

Note that 1:1's have a chicken-and-egg relationship in Convex, you have to create one before you can create the other, hence the { optional: true } in the example linked above.
