V3 suite/warehouse capability pack for email and outbox work. Gmail, Outlook, and IMAP are provider connections feeding the same warehouse; this pack bundles the kernel mail read/search/thread/body/send operations so workflow packs can depend on one governed email capability. Email-list v2 adds an opt-in metadata-only projection that removes inline bodies and blob pointers before recipe state. Sending is still the irreversible write-class operation owned by the mail-send kernel gate.
