Problem / User Need

Some campaigns may intentionally send the same file to multiple recipients or multiple times, while other campaigns must prohibit duplicate attachment use. The campaign model needs an explicit policy instead of relying on accidental behavior.

Acceptance Criteria

Campaign configuration can express whether duplicate attachment use is allowed.
Review detects duplicate file usage across recipients/messages where the policy requires it.
Violations can block send or require explicit review depending on campaign policy.
Allowed duplicates remain visible and explain why they are permitted.
The policy and any override decisions are included in protocol/audit output.

Notes / Decisions

Needs product decision on policy levels: allow, warn, block, or allow only within a recipient/message group.
