Gmail API + Directory API (27 commands): mailbox search/read/send/ trash/label/move, attachments retrieval, vacation auto-reply, filters, forwarding addresses, delegates, and Workspace user administration; message ingestion (get_incidents) with a bundled OCSF mapper. Service-account auth with domain-wide delegation (JWT RS256), runs on a remote engine (requires PyJWT + cryptography). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
