- MentionEditor: Enter sends (Shift+Enter for newline), remove @ button
- CommentThread: remove send button, full-width input, always show
input when comments exist (no need to click Kommentieren first)
- TranscriptionBlock: remove border-t above comment section (orange
background provides enough visual separation)
- Update placeholder in all languages to hint @mention and Enter to send

BLOCKERs:
- Remove direct AppUserRepository/CommentRepository access from CommentService and
NotificationService — replaced with UserService.findAllById() and UserService
(fixes layering contract from CLAUDE.md)
- Switch Optional<JavaMailSender> constructor injection — removes @Autowired(required=false)
field and ReflectionTestUtils hack in tests
- Add @RequirePermission(READ_ALL) to UserSearchController — prevents user enumeration
without read access
Data bug:
- Promote actorName from @Transient to persisted VARCHAR column (V18 migration)
- Set actorName in notifyReply and notifyMentions from comment.getAuthorName()
Architecture:
- Add @RequirePermission(READ_ALL) to NotificationController
- Introduce NotificationDTO — controller returns DTO instead of Notification entity,
eliminating lazy-load N+1 and AppUser field leakage
- Change mentions FetchType to EAGER — fixes LazyInitializationException outside transaction
- Add @Transactional(propagation=REQUIRES_NEW) to notifyReply/notifyMentions so a
notification failure cannot roll back the parent comment
- N+1 fix: replace per-ID findById loops with single findAllById bulk fetch
- Move collectParticipantIds to CommentService; notifyReply accepts Set<UUID> directly
Security:
- Escape displayName before injecting into renderBody HTML span
- Replace <a href="#"> with <span class="mention"> — no profile page to link to, and
the anchor's scroll-to-top behaviour is harmful
Tests added/fixed:
- markRead_throwsNotFound, markAllRead_delegatesToRepository, countUnread_delegatesToRepository
- markOneRead_returns401, @RequirePermission 403 coverage for both controllers
- postComment/replyToComment_triggersNotifyMentions_whenMentionedUserIdsProvided
- search_returnsAtMostTenResults now asserts $.length() <= 10
- XSS regression test for escaped displayName in mention.spec.ts
Frontend minors:
- relativeTime() uses Intl.RelativeTimeFormat (locale-aware, not German-hardcoded)
- aria-label uses m.notification_unread() Paraglide key (de/en/es added)
- <div role="button"> replaced with <button> (native Enter+Space handling)
- onDestroy clears debounceTimer in MentionEditor
- setTimeout(100) replaced with await tick() + requestAnimationFrame in CommentThread
- Notification prefs form uses checkbox name attributes + formData.has() pattern
