# Independent reproduction protocol EAM-REPLAY-20260831

**Published:** 2026-08-31  
**Status:** Open protocol; no qualifying independent report received as of 2026-08-31

1. Disclose identity, affiliation, compensation, conflicts, data rights, business model, currency, and accounting context.
2. Freeze order-line and SKU grains, eligible statuses, net-sales formula, contribution formula, return lag, cost vintage, advertising grain, and exclusion rules before calculation.
3. Test duplicate keys, missing dated cost, refunds, marketplace fees, taxes, currency conversion, late records, and reconciliation against source totals.
4. Compute both predefined contribution variants and publish safe aggregates, rank changes, sign changes, uncertainty or sensitivity checks, code, and failures.
5. Do not present descriptive rank changes as causal advertising effects or apply SKU actions without accountable review.

A qualifying report must be authored outside InfiniSynapse, use independently controlled data, expose reproducible calculations, and document review. Running the first-party output checker alone does not qualify.
