Data snapshot: 2026-W37

ISO week 2026-W37. 60 metric rows, one per (prompt × model). Every number the dashboard shows for this week is derived from these files. License: CC BY-SA 4.0.

Coverage this week

  • Stance classifier: The stance classifier was still on the empty Anthropic balance. gpt-5.5 10 of 10 and llama3.2:3b 9 of 10 stance-bearing cells are published as stance n/a at confidence 0.0, which means unmeasured, not neutral. The remaining llama3.2:3b cell was answered from the classifier cache.
    Corrected Stance for the 19 unmeasured cells was re-classified on 2026-10-07 from the published responses and grafted as a versioned correction; only the stance fields changed. /reports/2026-10-07-stance-classifier-correction/
  • Corrected 2026-10-07: Stance re-classified for 19 stance-bearing cell(s) published as na at confidence 0.0 because every classifier call failed on an exhausted Anthropic balance. Classified 2026-10-07 with anthropic/claude-haiku-4-5-20251001 from this week's published responses, using the same representative-response rule. No other field changed. Correction report. The corrected values are in the week’s manifest, data/manifests/2026-W37.json in the source repository.

The reasons and evidence are in the coverage table.
