**Verdict: 矛盾あり（doc comment が実装と不一致）**

該当箇所:

- `src/events.rs` `Action` enum の doc comment:
  ```rust
  /// Attach a tag to this aggregate. Open to anyone; not gated on
  /// ownership (multi-user collaborative annotation land here).
  Add,
  /// Detach a tag from this aggregate. Owner-only — `authorize_owner`
  /// rejects callers whose DID doesn't match the aggregate's owner.
  Remove,
  ```
  → これは `tag_post` の権限モデル（Add 開放 / Remove オーナー限定）をそのまま記述している。

- `src/server.rs` `relate_posts` の実装:
  ```rust
  // Both add and remove are an assertion on the source post — gate
  // both on source-owner authorization. Differs from tag_post where
  // add is open to any authenticated DID; tags are post-level
  // annotation, refs are a 1-to-1 claim "this post links there"
  // attributable to the source post's owner.
  self.authorize_owner(&args.source_post_id, &actor).await?;
  ```
  → **Add / Remove ともに source-owner-only**。

結論: `Action::Add` の doc comment「Open to anyone; not gated on ownership」は `tag_post` 専用の文言であり、`relate_posts` では誤り。`Action` は汎用 enum なのでコメントが tag_post 前提になっており、`relate_posts` の tool description や実装と矛盾している。修正は `Action` の doc を汎用化するか、`relate_posts` 側の tool description / 実装コメントで補足済みだが、enum 定義のコメントが誤導的。
