Test Core (4/6): 2333.4s measured vs 1770.9s predicted across 12 package(s) = 1.32x (warning past 1.3x, red past 1.5x). Heaviest overshoot: @objectstack/cli, predicted 579.6s, measured 785.5s. scripts/test-shard-timings.json is drifting from the runtime; refresh it before it reaches the red (see scripts/measure-test-shard-timings.mjs). Not a failure: this step stays green until the red bound.

NOT MEASURED -- Test Core: no ceiling table yet. scripts/test-shard-timings.json carries no `ceilings`, because it was written before the suite-duration ceilings existed; the first run of .github/workflows/shard-timings-refresh.yml after this check landed writes them. Nothing was graded and nothing failed. If this still prints after that refresh has merged, the refresh is not writing ceilings: that is a defect, file it.
