This package composes Campaign, Mail, Postbox, Files, Templates, Policy, Audit, and Access into one governed-delivery capability. Modules retain their own tables and lifecycle. The package declares installation and configuration expectations; it does not import module internals.

Reference journey

Select governed recipient and attachment data.
Build and review an immutable Campaign version.
Apply attachment, access, and delivery policy.
Deliver through Mail and/or function-bound Postbox targets.
Reconcile outcomes, acknowledgements, correction, and reports against Audit evidence.

Reference-readiness gates

The artifact remains a product package. Promotion to reference requires:

target-environment delivery and reconciliation tests, including an outcome-unknown transport result;
backup/restore and interrupted-dispatch recovery evidence;
security evidence for recipient, attachment, and postbox isolation;
operator runbooks for queue health, retry, reconciliation, and retirement;
keyboard, focus, screen-reader, and responsive workflow evidence;
privacy evidence for minimization, purpose, retention, redaction, and report access; and
version-pinned user and administrator documentation.

Optional Notifications, Portal, Reporting, and Workflow Engine integrations do not change the package boundary when absent.
