Arena probe matrices

Start here — free verify: https://councilof.ai/gspc-verify/ (or the free MCP tool verify_card at https://councilof.ai/mcp) · Full catalog: https://councilof.ai/catalog.json · Methodology: https://councilof.ai/methodology/ · Measurement, not certification.

Per-run probe matrices from the arena lane. Each arena_matrix_*.json records the benchmark, the run_at timestamp, the base endpoint and the lane it ran on (local Ollama, £0), then a summary giving n_measured, n_correct and accuracy for every model in that round. The n per cell is small and stated; read them as probes, not as board measurements.

Measurement is not certification. A repository, signed record or passing software test does not by itself establish current board admission, product acceptance or benchmark leadership.
