# Independent reproduction protocol CA-HASHED-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, jurisdiction, platform, and data rights.
2. Predefine buyer and order grains, pseudonymization method, eligible population, first-order event, repeat event, contribution formula, exclusions, return lag, and retention period.
3. Test duplicate keys, missing buyer keys, reversibility and linkage risk, refunds, fees, late records, and cohort stability.
4. Publish code, safe aggregates, sensitivity checks, failures, and limitations without exposing customers or commercially sensitive rows.
5. Separate descriptive cohort changes from causal treatment effects; do not activate ranking or outreach without independent governance.

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