No arbitrary .05 promotion bar from old notes. Read six ongoing C results.

Start directly on assigned seeds: no extra smoke or reused seeds. Freeze before scoring; no selection or retuning.\nReset gas_stats before EACH arm/block; save its edges, exact seed/config records and gas_stats() immediately, then rewrite result after each arm. Pair available cand/C0 rows without waiting for any third arm. Keep partial rows including null for missing arms; never repeat completed or uncheckpointed in-flight arms. On execution/setup failure return ONLY {\"blocked\":{\"step\":\"...\",\"error\":\"...\"}}.
