Test Core (6/6): 3395.8s measured vs 1935.3s predicted across 14 package(s) = 1.75x (warning past 1.3x, DRIFT past 1.5x), past the drift bound. Heaviest overshoot: @objectstack/runtime, predicted 632.5s, measured 1151.3s. Report only, on every event (this is a `pull_request` run): a shard's wall measures the run's load as much as the dataset, so this is a reading, not a failure. Refresh scripts/test-shard-timings.json (see scripts/measure-test-shard-timings.mjs).
