The essay's cases are living shells: a thinning US election office, a UK criminal bar stuck around 2,400, a Hungarian tabloid sold under the notification threshold. A named constitution that actually failed to reproduce is not on the page.
The Weimar Constitution was signed 11 August 1919. It had a Reichstag, enumerated rights, courts, a professional civil service, a bar, and a press. It was never formally repealed.
Article 48 let the president restore "public security and order," including by suspending named rights, if he told the Reichstag, which could vote the measures down. The US Holocaust Memorial Museum's article on Article 48 records Friedrich Ebert using it sixty-three times in 1923-24 and returning the powers; Paul von Hindenburg used it sixty times in 1932 as ordinary government. Clinton Rossiter, in Constitutional Dictatorship (1948), notes that the Reichstag elected 31 July 1932 sat on 30 August and 12 September. The Decree of the Reich President for the Protection of People and State — the Reichstag Fire Decree — was issued 28 February 1933 on Article 48(2), signed by Hindenburg and countersigned by Hitler, Frick, and Gürtner. The Enabling Act followed on 23 March.
Those steps had the surface of authorization. Germany still had lawyers and newspapers. The order did not reproduce.
Competing account: a liberal-constitutional order reproduces itself through political carriers — parties that will still pass ordinary statutes, a parliament that still sits, elites who will not govern by the emergency clause — not through replacement of the professional guilds.
The essay predicts that if lawyers, journalists, and civil servants replace themselves at the rate they leave, legitimacy holds. This account predicts you can have a full bar and a dead constitution.
They disagree on what to count. If the essay is right, the UK criminal-bar series and Brennan resignation numbers are the test. If political-carrier reproduction is the test, the ratio of emergency decrees to statutes is the test, and a recovered bar next to backlog-driven cuts to jury trial would pass the wrong cell.
Discriminator: a year in which professional headcount is not the binding constraint and emergency lawmaking has become the ordinary path. Weimar 1932 is on the record. A live analogue is any jurisdiction where the bar and the local press are stressed-not-failed while the share of law that never sees a floor vote keeps rising.
Fair. Elite defection and emergency-turned-ordinary are already named as two of the six stress vectors, and the essay already says a regime in trouble is several vectors on several classes at once. I am not reopening that.
What those rows still lack is a replacement-rate number of the kind the Bar and Brennan rows have. Weimar's use is that the binding failure was on those two vectors, and counting lawyers would have missed it.
