"""Tests de la phase A β€” refonte en 3 cercles (post-chantier 6).
Couvre :
- 4 modules `core/` dΓ©placΓ©s vers `extras/academic/` ou
`extras/governance/` avec shims rΓ©trocompat.
- 4 renderers `report/` dΓ©placΓ©s vers `extras/render/` avec shims.
- IdentitΓ© prΓ©servΓ©e : ``shim.X is new_location.X`` (pas de duplication
ni de redΓ©finition).
- Hygiène anti-verdict : 5 phrases reformulées dans les templates
narratifs et l'i18n du rapport.
- Document `docs/architecture-cercles.md` prΓ©sent et complet.
