- Read: every attachment/inline part from any mailbox (Kamo Mail, IMAP providers, Graph; personal and shared routes) is hashed in memory (temp file past 8 MiB, deleted on close), its global verdict looked up and, when unknown, checked by KamoAntivirus (origin MAIL_READ, bytes_stored=false). Harmful = 423 ANTIVIRUS_BLOCKED, not checkable = 423 ANTIVIRUS_CHECKING; reason/family also as X-Kamo-Antivirus-* headers. The SI mail tools read through these routes, so they are gated too. Listing never scans: AttachmentInfo carries **************** only for parts already hashed. - Milter placeholders (X-Kamo-Antivirus-Removed) list under the ORIGINAL name, removed=true, locked; never served or forwarded. X-Kamo-Antivirus message header exposed as EmailMessage.antivirus for the banner. - Send/draft (decision 11): device uploads and pasted images go through AntivirusGate.scanUpload (stored verdicts reused, never rescanned); a forward's parts get the read check. 422 ANTIVIRUS_BLOCKED with fileName, 503 ANTIVIRUS_UNAVAILABLE. - NATS antivirus.detection.mail (queue group antivirus-mail-detections): recipients resolved to members via mailbox holders, personal aliases, shared mailbox readers and alias domains; recorded per member (MAIL_INBOUND, counterparty = sender) so FILE_BLOCKED / THREAT_ALERT go out per org settings. - Notifications: ANTIVIRUS_THREAT_ALERT -> VIEW_ANTIVIRUS (core app, no feature row needed); FILE_BLOCKED/UNLOCKED belong to no app; catalog order. Preview samples for the 4 Antivirus templates. - configmap kamo.antivirus.* (enabled: kamowsantivirus is Ready). Needs kamo-shared-library b6c41d34 (HashUtils BLAKE3 on bcprov 1.70).
