Attachment deduplication (SHA-256 content-addressable storage): - Identical files stored once globally (m8sh/sha256/<hash>) - Reference-counted deletion: blob removed only when last ref deleted - StoreAttachmentDedup, DeleteAttachmentDedup, StoreAttachmentFromReader Comprehensive safety limits: - USER_QUOTA: 5 GB default (admins unlimited, 0 = unlimited) - MAX_ATTACHMENT_SIZE: 100 MB per file - MAX_ATTACHMENTS_PER_MESSAGE: 50 files - MAX_MESSAGE_SIZE: 1 MB body - MAX_CONVERSATIONS: 1000 per user - MAX_MESSAGES_PER_CONVERSATION: 10000 Block-domain shredding: - ShredAttachmentsForDomain deletes all blobs + metadata for domain - Dedup-aware: only removes blobs with no remaining references Assisted-By: Cline:anthropic-claude-sonnet-4-20250514
