GAL-2 Time Contract 5-Day Adversarial Characterization v1.0 Pre-Registration

This record preserves the frozen pre-registration package for the GAL-2 Time Contract 5-Day Adversarial Characterization v1.0. The package was created before the official run start and includes the pre-registration document, freeze notes, SHA256 manifest, hypotheses, tier table, claim boundary, failure criteria, adversarial schedule, Day 0 preflight requirements, evidence package requirements, known limitations, and publication rule. This pre-registration is for application-facing GAL-2 Time Contract behavior only. It is not a metrology accuracy test, not a UTC replacement claim, not a GNSS/PTP/NTP replacement claim, not an atomic clock replacement claim, and not a nanosecond or microsecond precision claim.
