- Measurement note
- Official ImageJev v0.3 A300+P300 pass 1 on 7 Oct 2026 via OpenRouter chat completions (openai/gpt-6-luna, low reasoning effort, unchanged v0.2 prompt/parser, max_tokens 384). This is the chat row; the OpenAI Decisions row is measured separately. Attempt 1 aborted on a mislabelled BMP image (public items only, not scored). 548 ok, 51 unparseable answers, 1 HTTP 520. Images are sent with their real MIME type; 7 BMP images were re-encoded losslessly as PNG and 5 images over the 6 MiB request limit were downscaled to 2,048 px on the long side. Provider failures (HTTP errors, timeouts, error bodies) count wrong at cost 0; unparseable answers count wrong at their billed cost. No retries.
