[PAID BOUNTY - $660] Note Locking - Biometrics/PIN

[warpspeedopen-source]

Bounty Overview

Build note-level locking for the warpSpeed Notes experience using biometrics, device authentication, or a user-defined PIN.

This bounty gives users a private vault inside Notes. Users should be able to lock new or existing notes, clearly see which notes are locked, and unlock them only after successful authentication.

Locked notes must stay hidden or obscured until unlocked, and the app should require re-authentication after app restart or after a configurable timeout.

This bounty is part of the warpSpeed OPEN developer bounty programme.

I can begin immediately once the claim is confirmed. Implementation plan: build the React Native/TypeScript note-locking feature with biometrics/PIN authentication, hidden/obscured locked-note states, secure unlock/settings flows, timeout/restart re-authentication, lock indicators, and reusable auth/locking UI/components.
