Merge Risk: 🟡 Moderate · up to Keeping messages from deleted users introduces a report path that can attribute an orphaned message to an arbitrary user and contribute to automatic bans. It also blocks migration rollback and hides the Report action for those messages. Some new accounts can be created without seeing the consent notice. Resolve these before merging; the remaining display and validation issues are small. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Match the current user's profile, not every user profile.
When Alice visits /u/bob, this condition marks the Profile item active even though the item links to /u/alice. Compare the current path with the authenticated user's profile path instead.

Show the consent notice when step 1 submits directly.
If there are no suggested contributors, goToStep2 calls submit() without displaying step 2. On an installation with no existing users, the first account can therefore be created without showing this Terms & Conditions and Privacy Policy notice. Place the notice on both submission paths, or show it before either path submits.

Guard nullable username in mention filtering.
ChatUser.username is nullable, but filteredMentionUsers calls u.username.toLowerCase(). Under the repository's strict TypeScript settings, this produces a nullability error. Guard the access:
