YvvandClaude Opus 5.5 d762301706 v3 : inertie à cinq crans — moteur, données, serveur (L10)
Moteur (ld-engine/inertia.rs) : cinq crans, M_k = 50, 50, 55, 60, 66 % ;
s_k = 60, 67, 75, 83, 90 % de « pour » au-delà de C à la participation
habituelle p̃ ; G_k = ln(1 − (s_k − M_k)/(1 − M_k)) / ln(p̃). p̃ = médiane
des votants des propositions du groupe (au moins 5, votées dans l'année),
sinon la référence 2C/W ; bornée à [1 %, 50 %]. Le changement d'inertie
hérite du cran de l'article (remplace « inertie + »). Un seuil qui tombe
sur un entier n'y gagne plus une voix par arrondi.

Données : migration 0005 (les quatre mots deviennent 2 à 5, gardés tels
quels dans *_legacy ; adoptions intactes ; journaux inertia_changes et
inertia_amendments). Seed : 3 partout, 4 pour E1 et E2. Amendement
d'inertie gardé (E1, E2 : 3 → 4, seulement si aucun vote n'a changé leur
inertie ; une proposition d'inertie ouverte reste ouverte, votée au
nouveau cran), journalisé, une seule fois, republié.

Serveur : participation mesurée une fois par jour (settings), échelle
dans les seuils, le balayage et l'adoption ; crans, M, G, s_k, p̃ et sa
source servis au client.

//! Inertia in five levels (ADR 0007): the levels and the scale served, the
//! usual participation of a group, the change of inertia voted at the level
//! of its article, the migration of the four words of before, and the
//! amendment that raises E1 and E2 to level 4 in an existing base.
