The table has an empty cell in the 'Not Signed in' column for Note::Create operation. This should be explicitly marked as 'No' for clarity.

Suggested change

	| Note::Create(投稿) | Yes | No | Yes | Yes | Yes | No | | |
	| Note::Create(投稿) | Yes | No | Yes | Yes | Yes | No | No | |

The Reaction::Fetch operation allows 'Not Signed in' users to fetch reactions (marked as 'Yes'), but requires authentication for other roles. This seems inconsistent - anonymous users shouldn't have more permissions than authenticated users.

Suggested change

	| Reaction::Fetch | Yes | No | Yes | Yes*(Role:Normalなアカウントのみ) | Yes*(Role:Admin**以外**に実行可能) | No | Yes | |
	| Reaction::Fetch | Yes | No | Yes | Yes*(Role:Normalなアカウントのみ) | Yes*(Role:Admin**以外**に実行可能) | No | No | |
