This proof bundle documents a reproducible Y2038 boundary experiment comparing a raw 32-bit legacy workload against a mediated continuity path. The raw legacy path fails across the Y2038 boundary with:- event ordering failure- TTL validity failure- scheduler coherence failure The mediated path preserves:- monotonic event ordering- TTL validity- scheduler coherence Additional evidence in this bundle demonstrates syscall-level interception in C for:- time()- gettimeofday()- clock_gettime() Summary results: Raw legacy path:- SUMMARY order_fail=1 ttl_fail=8 sched_fail=18 Mediated path:- SUMMARY order_fail=0 ttl_fail=0 sched_fail=0 Defensible claim:A raw 32-bit legacy workload fails across the Y2038 boundary, while a mediated continuity path preserves event ordering, TTL validity, and scheduler coherence across the same boundary. Scope note:The evidence here is workload-scoped, not universal. However, the results show that GAL-2 is not merely detecting the Y2038 failure. It is mediating time consumption in a way that preserves operational continuity where the raw 32-bit path collapses. This supports the view that GAL-2 has credible potential as a legacy-system continuity layer for Y2038, pending broader validation.
