Zero-trust home vault
The security foundation. Hardware-rooted identity, end-to-end encryption, and a hard architectural rule: the outdoor display never renders document content.
- Address-bound vault — payload rejected if GPS + street + device don't match
- Ed25519 / AES-256-GCM chain-of-custody from sender KMS to your phone
- Glance-only outdoor UI — count, sender category, urgency; never body text
- Tamper zeroization — keys wiped on physical compromise
- Multi-tenant household vaults, duress PIN, expiring delegate tokens
