# Independent reproduction protocol ECOM-MARGIN-20260831

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

1. Use lawfully obtained retail data and disclose identity, affiliation, compensation, conflicts, platform, currency, tax jurisdiction, and data rights.
2. Predefine order-line grain, SKU map, exclusions, net-sales and contribution formulas, fee and ad allocation, return timestamp, lag window, and publication threshold.
3. Reconcile source totals before joins; report duplicate keys, orphan marketplace IDs, currencies, refunds, and late-arriving records.
4. Publish code, safe aggregates, mapping coverage, sensitivity checks, failures, and limitations without exposing customers or commercially sensitive rows.
5. Compare before-return and after-lag contribution; do not claim causation or recommend automated repricing or restocking.

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