PD-80 — Décomposition step 6a¶

Metadata¶

Story : PD-80 — Scellement instantané < 1h
Date : 2026-03-12
Stratégie : séquentiel (11 modules, dépendances linéaires)

Parallelization¶

mode: sequential
reason: >
  Les 11 modules ont des dépendances d'import entre eux (entity → service → processor → module).
  Un mode by_level apporterait peu de gain car les interfaces sont partagées.
