Sync does not have to turn a local vault into a cloud database. The edge can identify an account, store opaque replica frames, and deliver updates without learning what those updates contain.

SQLite wants a file. A privacy vault wants durable relational storage that stays fast as its item count, indexes, and encrypted attachments grow. Putting a SQLite virtual file system on IndexedDB can bridge those worlds, but it makes the bridge part of every database operation. For NT² Vault, the browser vault file belongs in the Origin Private File System.

One screen can make two security events look like a single login. We keep them separate because opening encrypted data and proving an identity to a server are different jobs with different risks.

A vault can encrypt everything with one key and still claim that its data is encrypted. We wanted a more useful boundary: each item and attachment gets its own content encryption key, while the vault key protects those keys.

A salt is not a secret. Still, where it lives changes who can assemble a password-guessing system. NT² keeps the KDF salt and password verifier with the local vault, so unlocking begins and ends on the device.

The useful question is not whether an AI agent can write code. It is how to give agents enough context and autonomy to move quickly while keeping product decisions, security boundaries, releases, and customer-facing actions under explicit human control.

In the era of massive cloud-first applications, we often overlook a powerful alternative: the Progressive Web App (PWA). Why maintain a heavy, expensive, and potentially vulnerable server infrastructure when the modern browser is capable of running a full-featured, secure, and high-performance application entirely on the user's device?

Self-sovereign identity sounds abstract. In NT², the practical version is simpler: your vault can prove itself, recover without a help desk, and share under your control while NT² stays blind.
