living pointer — numbers from councilof.ai/api/gspc

living board pointer, unsigned 12 Aug stamp

add measured board 2026-08-11 (RunPod 3090)

expanded measured bank n=33 (2026-08-05 board)

card: point configs at items.jsonl (19 rows) instead of machbench-draft.json, which is one JSON object and rendered as a single row

add meta.json — repo had no data file, so the viewer and datasets.load_dataset() both failed

add items.jsonl — repo had no data file, so the viewer and datasets.load_dataset() both failed

Point default config at the items; results move to `runs`

MachBench draft items
