Records the closing state of Fase 10: spec coverage now 100% on the H-series CUs, full FK on-delete audit table, 5 architectural decisions (Keycloak not cleaned up on account delete, sole-member must dissolve, type-the-name dissolve confirmation, client-side language detection, trash via RPC). Bumps the MVP2 progress to 2/6 and the test totals to 360 active + 3 skipped. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
