GAL-2 Y2038 RC4 Sandbox Authority Crossing: 30-Minute Controlled Post-Boundary Time Contract Continuity

This package documents a controlled GAL-2 RC4 Time Contract engine characterization across the signed 32-bit Unix time boundary. A copied GAL-2 RC4 Time Contract engine was run as a local sandbox with a controlled Y2038 test clock. The engine produced governed GAL-2 Time Contract output beyond 2038-01-19T03:14:07Z for a 30-minute post-boundary characterization window. Final result: PASS_Y2038_RC4_SANDBOX_30MIN_POST_BOUNDARY_CONTINUITY Key results: 180 post-Y2038-boundary contract samples 0 gal2_time backward steps 0 monotonic_sequence non-increasing steps 0 invalid outputs 0 missing required contract-field rows safe_to_consume present contract_hash present source_lineage declaring gal2_fractal_time_authority, rc4_contract_engine, and y2038_controlled_clock final public secret scan PASS with findings_count=0 This package is intended to make the Y2038 authority-crossing claim inspectable, challengeable, and reproducible at the RC4 contract-engine sandbox layer. The question tested is narrow: Can the GAL-2 RC4 Time Contract engine maintain governed Time Contract behavior beyond the signed 32-bit Unix time boundary under a controlled Y2038 clock? In this run, the answer was yes under the declared test conditions. Together with prior Docker linux/386 raw signed-32 failure evidence and real-daemon consumer-gate evidence, this package supports the bounded claim that GAL-2 provides an operational continuity path for protected legacy workflows by moving operational time authority away from signed-32 Unix time and into governed GAL-2 Time. Reviewers are encouraged to inspect the archive, verify the hashes, challenge the scope, and attempt independent reproduction or falsification. Scope boundary: This package does not claim that GAL-2 patches arbitrary unmodified legacy binaries from the inside. It does not claim that the production AWS/API authority crossed 2038. It is not platform-level Y2038 remediation, production SLA evidence, UTC accuracy certification, or metrology certification. This is controlled application-facing Time Contract continuity evidence.
