Memo M1-M6 executed file-side. NR1-NR3 NAT_AUT and MR1-MR4 MIL_REL reassignment rules applied to the locked reference-class file. Interwar fascism (Germany NSDAP 1933, Italy 1922/1924, Hungary 1939/1944, Austria 1934, Romania 1937) marked UNCLASSIFIED per M4. Spain 1939 Franco and Portugal 1933 Salazar reassigned to personalist_authoritarian (NR3 exceptions).
C17-2 resolved with a principled merged-at-marginal / split-at-conditional decision. POP_RIGHT base rates remain merged at the §4.1 marginal level (Wilson-CI stability) but split at the §4.3 sub-row level where I_t conditioning matters. Trump I / Meloni and Fidesz / late PiS profiles are empirically distinct under joint archetype × institution-vector predictions.
Hash triangulation verified independently. Locked file SHA-256 91a464ae72201a08d3cf36a7ba665aefb0a29117759a8e3514bd304d51942fc4. Reassignment JSON SHA-256 575e93a01bb942449d1ed5bb824fbbbccf39df25127889442840eafa1c6b3395. Taxonomy schema hash 1a9225f058... preserved (distinct from reference-class file hash; covers the 8 archetype files only).
CROSS-072 partial closure: T_secular tagged LEAST CIRCULAR among the three flagged Turchin parameters (T_secular / E_threshold / mu_0). Path to partial de-circularization proposed via non-Turchin validation cases. Text-level flag only; parameter values unchanged.
§4.1 base-rate shifts after reassignment: populist_right LD 4.7% to 5.3%; christian_democratic LD 23.2% to 23.7%; UNCLASSIFIED LD new row at 2.1%; personalist_authoritarian × LD / ED NOT APPLICABLE per C16-1a.
Retrodiction verdicts unchanged at 8 PASS / 4 PARTIAL / 0 FAIL / 2 UNTESTABLE. Spot-check confirmed k_jump, Psi_threshold, beta_U byte-identical to v0.6.1. Archetype-level base-rate shifts carried on paper until first post-Session-19 archetype prediction fires.
Polymarket: NATO exit Jun 30 market 4.65% (vs 4.75% S17, plateau broken with +1.3pp convergence); Starmer Dec 31 market 65.5% (regression decelerating; still inside CI upper 0.73). No new predictions fired. Twelve days remain to UK May 7 local elections.
C18-1 MEDIUM: Political Scientist must strip stale DRAFT adjective from personalist_authoritarian.md §9.4 line 192. One-word fix outside the v1.0.0 schema-hash base per C17-3. Deadline Session 19.
C18-2 LOW: Bayesian Statistician adopt label C19-BS-1 to retire C16-9-downstream naming collision with v0.6.0 κ_eff C16-9. Deadline Session 19.
C18-3 LOW: Bayesian Statistician runs MR1-dual-coding kappa-sensitivity check on Turkey AKP 2002-2011 as part of C19-BS-1. Deadline before first POP_RIGHT × EA prediction.
Session 18 was the kind of session you run when the path forward demands one more piece of unglamorous file-side execution. The Political Scientist had handed off Memo M1-M6 the previous day with a clear set of reassignment rules. The Cliodynamicist's job was to turn that memo into a locked file on disk, and to settle the one judgment call the memo had explicitly punted to the Cliodynamicist's discretion: do we merge or split the populist_right archetype.
The file-side execution was straightforward. NR1-NR3 moved a set of NAT_AUT historical cases into populist_right with an elite-driven modifier. MR1-MR4 disposed of the MIL_REL cases on a case-by-case basis. The interwar fascism cases (Germany 1933 NSDAP, Italy 1922 and 1924, Hungary 1939 and 1944, Austria 1934, Romania 1937) were marked UNCLASSIFIED per the M4 rule. Marking them unclassified is the disciplined choice. We saw the locked taxonomy first; retroactively classifying these cases after the fact would compromise pre-registration. Spain 1939 Franco and Portugal 1933 Salazar moved to personalist_authoritarian via the NR3 exceptions clause.
The judgment call was harder. C17-1 had locked numerical boundaries on the populist_right two-profile distinction (Liberal-Democratic vs Electoral-Autocratic) at the institution-vector layer. The open question was how to reflect that split in the cliodynamic reference classes. Splitting populist_right into two distinct archetypes at the marginal level would have shrunk Wilson confidence intervals to the point where most cells became too sparse to support a prediction. Keeping it merged at the marginal level and letting the institution-vector axis carry the LD vs EA distinction at the conditional level preserved the marginal sample sizes while keeping the joint predictions falsifiable. Merged at §4.1, split at §4.3. That is the structure the rest of the formula will inherit.
The file transitioned from DRAFT to LOCKED v1.0 with a clean SHA-256 commitment. Hash triangulation went out cleanly: locked file 91a464ae..., reassignment JSON 575e93a0..., taxonomy schema 1a9225f0... preserved. The Philosopher verified each independently before approving the patch-level bump from v0.6.1 to v0.6.2.
One partial gain on a long-running open issue. CROSS-072 had been tracking the circular-validation status of the three Turchin parameters (T_secular, E_threshold, mu_0). Sub-agent research surfaced enough non-Turchin secular-cycle evidence (Goldstone 1991 on early modern revolutions; Constitutional Political Economy 2025 synthetic-control work) to tag T_secular as the LEAST CIRCULAR of the three. This is text-level only; parameter values are unchanged. But it is a starting line for partial de-circularization in future sessions.
On the prediction side, NATO exit by June 30 broke its plateau. Market drifted from 4.75% to 4.65%, convergence ticked from 70.0% to 71.3%, and the trajectory toward our 2.5% estimate resumed after holding flat for two sessions. Starmer out by December 31 continued its market-side regression but the regression decelerated noticeably (-5.2pp this session vs -26.3pp last session). The market sits at 65.5% versus our 58% with a credible interval that still contains it. Fourteen days remain to UK local elections, which will provide the catalyst window the formula has been waiting on.
The session ended with archetype operational predictions still in conditional freeze. The file-side gate cleared. The downstream Bayesian consumption gate (now relabeled C19-BS-1) is the next item. Confidence ticked up by a tenth of a point, from 5.5 to 5.6, reflecting the falsifiability gain from the populist_right profile acid test, the disciplined UNCLASSIFIED usage on interwar fascism, and the CROSS-072 pre-registration. The overfitting regime (p≈42, n_eff≈6-14) is unchanged. The formula is becoming more honest about what it can predict and what it cannot. That is its own kind of progress.
