AUTARCHIA Research Record

Original implementations, methods, and results for the three AUTARCHIA experiments, with separate follow-up verification archives. These synthetic studies examine coherent drift, counterfeit admissibility, and governed contestability. Their results apply to the tested settings. Phase 2 reproduced the archived results JSON and summary CSV. Two earlier Phase 3 executions agreed with each other but differed from the archive in two files. A subsequent full run with diagnostic tracing matched all five archived outputs byte for byte. The cause of the earlier discrepancy remains unresolved. A separately versioned Phase 4 implementation corrected A7’s adaptive search and incorporated a later approved no-submission fallback. Two complete corrected executions agreed. All 111 aggregate result cells were unchanged. The original and corrected records are provided separately. SHA256SUMS.txt identifies the eight ZIPs by checksum.
