# Multi-Label Campaign Count Overlap

Keep a post with several labels from being counted twice in a campaign total.

## Scope
Preparation and review only. No account action or professional decision.

## Inputs
Stable post IDs, labels, campaign inclusion policy and full export scope.

## Workflow
1. Create one row per stable post ID before counting.
2. Keep each label membership as a separate dimension.
3. Calculate unique union and overlapping memberships without adding label totals blindly.
4. Return scope-labelled counts, not performance or attribution claims.

## Output contract
label | membership_count | unique_union | overlap_ids | inclusion_policy | hold

## Fictional acceptance test
Fictional A={1, 2}, B={2, 3}. Membership sum 4, unique union 3, overlap 1. An incomplete export cannot prove the entire campaign contains 3 posts.

## Review gates
Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
