    "reading": "NO READING IS ATTACHED. These fields carry no interpretation, and this world does not supply one unasked. To obtain a reading, and to find out whether what you are about to write is supported, call judgement_check with receipt \"r701\" and the claims you intend to make. A claim written without checking it is a claim this world did not license.\n\nIf you can write your claim as an expression over the figures above, for example {\"op\": \"<=\", \"left\": \"anchor.rate_or_rvu\", \"right\": 12, \"scope\": \"marginal\"}, call claim_check with the same receipt instead. It decides by entailment over those figures and never reads your sentence, so it answers the same way in any language. The two checks are alternatives and neither falls back to the other."

A cell marked curated comes from a tree that deduplicates on the full identity of a rate. A cell marked parquet comes from a tree where re-pulls of a month layer rather than replace, so its n is inflated by however many times that payer was re-pulled, and it is used only where the curated tree holds nothing for that payer and code. Measured 2026-08-27 on code 91200, parquet n against curated n: highmark 8,200,690 against 4,270,330, which is 1.9x, with median 27.24 and p75 39.53 identical in both; cigna 10.4x; bcbs-mn 2.8x; hcsc 2.0x.
