# Independent reproduction protocol HTAB-KEYS-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, experiment context, and decision authority.
2. Pre-register assignment unit, canonicalization rules, key bridge, eligibility, primary, guardrails, horizon, and stopping rule.
3. Test duplicate keys, normalization collisions, dual exposure, unmatched rows, timing, SRM, missingness, attrition, and join cardinality.
4. Publish de-identified data or sufficient statistics, mapping code, SQL, intervals, exclusions, sensitivities, failures, and limitations.
5. Keep collision rows visible; hold decisions where identity resolution cannot be independently audited.

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