The Muqaṭṭaʿāt Research Program: Pre-Registrations, Instruments, Census Outputs, and Reproducibility Records

This deposit freezes a procedural-blind replication design for four pre-existing computational endpoints concerning the Qurʾanic disconnected letters (al-ḥurūf al-muqaṭṭaʿa): R1 A16B host assignment, R2 Threshold-v2 census and branch capstone, R3 T4-J2 joint assignment, and R4 CI-1 omnibus. A qualifying replicator receives a fixed Qurʾan corpus, a bilingual opening census, and a complete prose-and-equation specification, and writes an independent implementation. The original code, intermediate matrices and adjudication key are not supplied. Source-of-record values from earlier stages are already publicly discoverable under concept DOI 10.5281/zenodo.22832262, so this release does not claim that the targets are secret. The safeguards are procedural. The adjudication key is precommitted by SHA-256 below, which prevents the targets from being moved after replication. The replicator signs a prior-exposure record at acceptance and a non-consultation and independence attestation at deposit. The replicator's complete implementation and outputs are sealed and hashed before the key is opened. WINDOWS-ALL-1 is excluded because the surviving archive does not contain a unit-construction rule sufficient to reconstruct its historical result independently. This is recorded as an archival discrepancy, not a replication failure. This deposit is a methodological commitment. It reports no replication result.
