 `phpbbmodders/copylinks` clicks a topic title, a post subject and an FAQ question and shows each one's icon turned into a tick, with the copy to the clipboard stubbed, since headless Chromium may not write to it. It also saves the ACP settings. Use `--seed` with seed-forum's standard fixtures for a topic with replies.
 
+`phpbbmodders/seenotes` needs `--seed` with seed-forum's standard fixtures; it then runs seed-forum's `bin/seed-seenotes-fixtures.php` from the same folder, which gives the members reasons, notes and warnings. Reasons show only to staff, so every shot is taken as the admin: a post's mini-profile with the reason, a profile with a reason and one with NONE, the MCP post details notice, MCP → Moderator notes, ACP → Manage users → Moderator notes, and the ACP reasons and settings pages (in full).

 `phpbbmodders/topicclaim` needs `--seed` with seed-forum's standard fixtures, for its `forum_moderator` user. That user claims the busiest topic with a note, and the admin claims another topic in the same forum. Claims show only to moderators, so every shot is taken as the admin: the forum's topic list, the claim notice on the topic page, the claim page (with take over, transfer and release), MCP → Claimed topics and the ACP settings.
 
 `phpbbmodders/printallposts` sets the board to two posts per page, so the busiest topic spans two pages, then saves the **Topic tools** menu open on it and the **Print all** page showing every post, both as a guest. Use `--seed` with seed-forum's standard fixtures.
