System SAFE Area of Focus

The infrastructure that protects everything else — devices, storage, network, encryption, credentials, and backups.

Step 1 of 4 on the dependency ladder (System → At-Home → Financial → Estate) — the first rung — everything else depends on it · next: At-Home. The Modules below are sequenced to build on each other.

• S-01The Devices ModuleEvery physical or virtual device — phones, computers, drives, routers, smart home gear, security keys, hardware wallets, even the old hard drives and USB sticks in a drawer — with the metadata that lets the system survive loss, replacement, or inheritance.
• S-02The File Storage ModuleThe master record of how your filing system is organized — the four SAFE areas, where each lives, naming, retention, and archive policy.
• S-03The Network ModuleThe structure and access points of your home network — router, Wi-Fi, ISP, and advanced configuration — so it can be maintained, troubleshot, or handed off.
• S-04The Encryption ModuleThe encryption you rely on — full-disk, encrypted containers, hardware-level encryption — one entry per method, carrying the instructions your future self or an heir needs to decrypt.
• S-05The Passwords and Passkeys ModuleHow the family's passwords and passkeys are managed — the password manager, MFA methods, backup codes, and passkeys. One entry per mechanism; not a list of accounts.
• S-06The Backup and Synchronize ModuleHow your data stays consistent and survivable across devices and locations — what is synced or backed up, with which tools, on what schedule, and how recovery works.
