What does a seller rating leave out for a machine buyer?
From MCC-001, an essay: a hypothesis, not a measurement.
The short answer
The part a machine is unusually well placed to use. The essay argues that a single score compresses away the conditions, the recourse and the comparability a buyer needs, and that the compression suits human attention rather than machine judgement.
As published in the issue
But “Merchant X: 94/100” leaves the economic judgment unresolved. A fast, cheap provider with poor recourse may suit a routine purchase and be unacceptable when failure would interrupt an operation. A price can look competitive against services that would not satisfy the task.

Why it matters
Ratings are the obvious answer to the machine-buyer problem, and the sector is reaching for them. If the discarded detail is the useful part, standardising the evidence is a different project from standardising the verdict.
What we measured
Nothing here was counted. Our measured series does test where a published label and independently observed behaviour diverge, and those answers are linked below; the essay's wider argument about compression has not been put to a test.
