- CommentAttachment link table (comment <-> file) + migration - fileIds in create/update comment; update replaces the whole set, synced in one transaction with the comment - CommentDto.attachments; empty for deleted comments - Soft delete drops attachments so GC can collect the files - Max 10 files per comment, ordered by upload time (uuid v7) - Registers comments as a file owner - Rename CommentAuthorExpanderService -> CommentExpanderService (expands authors and files) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
