## O que é

O **MatVerse Memory Registry** é a superfície pública do stack de memória verificável.  
Ele expõe narrativa institucional, critérios de admissibilidade, prova pública, deploy status e um verificador local do operador Ω.

## O que a página resolve

- substitui o estado de erro de configuração do Space por uma homepage funcional
- concentra landing page e dashboard no mesmo endereço oficial
- apresenta prova pública em formato legível para revisão externa
- mantém o regime **fail-closed** visível: módulos não admissíveis aparecem como bloqueados, não como sucesso cosmético
