GAL-2 Historical Leap Replay Pack (2026-04-21): Controlled Authority-Side Injection Evidence and Real Production API Strict-Ordering Probe

GAL-2 Historical Leap Replay Pack collected on 2026-04-21. This package presents controlled leap-second-like evidence for GAL-2 together with a real production API strict-ordering probe. It combines historical replay controls, authority-side perturbation against the real GAL-2 daemon ingest path, independent observation, positive-control validation, and direct polling evidence from the production API. The package contains five core components. Part A documents a historical control replay across the 27 historical UTC leap-second events. In this replay, the RAW_STEP control path produced strict-ordering issues in 27 out of 27 events due to duplicate timestamps, while SMEAR_CONTROL produced 0 out of 27 strict-ordering issues. A GAL-2 consumer-path replay dataset is also included for comparison. Part B documents active authority-side perturbation against the real GAL-2 daemon ingest path. Across all 27 historical events and two perturbation modes, raw_step and backward_jump, the system completed 54 out of 54 runs with zero backward steps, zero duplicate steps, and zero errors. These results support the claim that GAL-2 can preserve a strictly increasing consumer path under controlled authority-side leap-second-like discontinuities. Part C provides independent observer validation using CLOCK_MONOTONIC_RAW. Under both perturbation modes, the independent observer confirmed zero backward steps, zero duplicate steps, and zero nonpositive monotonic intervals in the served GAL-2 consumer path. Part D provides a positive control. A deliberately broken GAL-2 consumer-path trace was injected, and the strict-ordering detector correctly identified the injected failure in 27 out of 27 events. This confirms that the detector is not blind and that the pass results in the main experiments are meaningful. Part E provides a real production API probe. Direct polling against the production endpoint https://api-v2.gal-2.com/timeproduced 2000 samples with zero backward steps, zero duplicate steps, and zero request errors. This supports strict-ordering continuity of the real GAL-2 production API under sustained polling in real network conditions. Interpretation This package supports a strong but scoped claim: GAL-2 can preserve a strictly increasing consumer path under controlled authority-side raw_step and backward_jump perturbations, making leap-second-like discontinuities operationally irrelevant for strict-ordering consumers under this controlled ingest-path injection model. This package also supports strict-ordering continuity of the real GAL-2 production API under sustained polling in real network conditions. Scope note This package is not presented as a public production-API leap-second replay proof, because the current public API surface does not expose replay or authority-side injection controls. Rate-sensitive and interval-sensitive results are included in the package and should be interpreted separately from the strict-ordering continuity claim.
