Two corrections the plan did not carry, both found by running the instrument:
- A question matching nothing still returned the top eight by tie-break -- a
confident guess wearing a denominator. The closed rule set gains
no_lexical_match, so the known-negative returns a measured empty set with
every considered concept named in withheld.
- The stage-one document prior summed overlap across a document's units, so it
measured document SIZE. Measured on K2 for the price question: the
competition document sums to 6.0 over 79 concepts (0.076 each), the price
document to 2.0 over 1. The prior is now a density; the price-form gold moves
from outside the top eight to rank 1. Found with that answer visible, which
the measurement document states beside the number.
