MétaCan

1,000 works · Opus 4.8 · GPT-5.6 (high) · Grok 4.5 · one locked rubric

The field’s boundary is not a line. It is a region.

Three frontier models screened the same 1,000 works, drawn from the real frame with known selection probabilities, against the same locked rubric on its full eight-field payload. Of the 51 works any model called metaresearch, only 19 (37.3%) were called metaresearch by all three, and 24 (47.1%) rest on a single model's opinion.

Two screeners can agree on a rate while finding almost entirely different works. At a ~1% base rate, the settled rejects buy 98% agreement for free — which is why an agreement statistic computed over the whole sample tells you nothing about the boundary, and why the table below, not a percentage, is the deliverable.

The three models are not interchangeable

How many of the 1,000 works each model called metaresearch (tier T1 or T2), on identical input. T3 is adjacent and does not count as in scope, which is why a model's count can never exceed the 51 works in the dossier.

Swap which model you call “the screener” and the size of the field moves. That spread — not the binomial confidence interval on any one model's labels — is the honest uncertainty on how big Canadian metaresearch is.

The disagreement dossier

All three verdicts, confidences and reasons side by side. These are the works against which the inclusion criteria have to be written — because these are the works on which reasonable screeners, given the same rubric and the same evidence, disagree.

What the screen actually found

Three frontier models (Opus 4.8, GPT-5.6 high, Grok 4.5) screened the same 1,000 works from the REAL 4.3M frame, on the rubric's FULL eight-field payload, with randomized manifest-logged chunks and harness-written labels: every defect D1, D2, D11 and finding 16 identified, repaired. Design-weighted base rates span 1.89% to 3.54% (1.9x). But the sets are the finding, as finding 16 predicted: of the 51 works ANY model called metaresearch, only 19 (37%) were called metaresearch by ALL THREE, and 24 (47%) rest on a single model's opinion. THE FIELD'S BOUNDARY IS NOT A LINE THE MODELS SHARE; IT IS A REGION THEY EACH CUT DIFFERENTLY. GPT-5.6 also violated the locked output schema on 18 of 1,000 records, writing genre values into the tier field, which the manifest validator caught. The deliverable is not the base rate: it is the disagreement dossier, the 51 works that mark the empirical boundary of the field and against which the inclusion criteria must actually be written.
