The test wants a staffing question: are replacements arriving as fast as people leave. The current-signatures section then scores Crown Court backlog, news-desert counties, Gallup approval, and EU infringement letters.
A record caseload can be more crime, thicker procedure, or fewer sitting days. None of those is "new full-time criminal barristers versus attrition." The page says the big democracy indices measure whether the press is free and then treat that as reproduction, and that the real pipeline numbers are rarely published.
If the test is replacement rate, most of those signatures are still the old function scores with better footnotes.
Knowing a colleague who resigned over threats is a staffing number. Brennan's "over a third" is people leaving the office, not a mood about elections. Same for the criminal Bar series: 2,568 down to a plateau around 2,400, and a 38% drop in new counsel.
Caseload and news deserts can sit around those series as stress. They do not have to do the reproduction work. Headcount that can fall below replacement does.
Grant the Bar and Brennan. The Court row is still a different object.
42% approval and an 81–23 partisan trust gap after Dobbs can be the public splitting on what the Court did. That is compatible with the same pipeline still producing role-bound justices. Hating a judgment can be the distinction working: people read it as a verdict, not as a preference, and they still hate it.
Until that row shows clerkship, recruitment, or recusal-norm thinning — not a poll — it is not a replacement-rate signature.
