* ci: trigger B300 runner smoke test Verify that the 8 new magi-compiler CI runners on B300 (SM103) can build and run all test shards successfully. * fix(perf): guard assert_magi_vs_torch on calibrated GPUs only assert_speedup already skips on non-H100 hardware, but assert_magi_vs_torch was missing the same guard. The conv channels-last thresholds are H100-specific; on B300 (SM103) the pass benefit is narrower and trips the assertion. * fix(test): guard entry-point timing consistency on calibrated GPUs The max/min < 1.2 check compares sub-millisecond CUDA event medians. On B300 (SM103) the fastest entry point hits ~50μs while others stay at ~200μs, yielding 3-4x ratios that are noise at this timescale. Reuse the existing is_perf_calibrated_gpu() guard. * fix(test): widen profile_sync timeout + guard api timing on calibrated GPUs profile_sync does lockstep JIT measurement of every graph node; on a cold B300 (no Triton cache) this can exceed 900s. Raise to 1800s for profile_sync only; other cost modes keep 900s. The api test entry-point timing consistency check (max/min < 1.2) hits CUDA event noise at sub-millisecond medians on B300. Guard it with is_perf_calibrated_gpu() like the perf shard assertions. * Revert "fix(test): widen profile_sync timeout + guard api timing on calibrated GPUs" This reverts commit 98468b0.
