Design notes on document encryption, access boundaries, and auditability—plus why 'blockchain' is usually the least interesting part of the system.
Encrypted State: Key Required
Click the vault lock to simulate key rotation.
My approach was role-first: define who can do what, then derive keys and storage rules from that.
Audit logs are only useful if they're queryable and explainable. I optimized for 'what happened and why' over cryptographic novelty.
The takeaway: secure systems are mostly about careful defaults and predictable recovery paths.
Give it a quick clap, share it with colleagues, or book a 1-on-1 session to dive deeper into the code.
