The Sovereign Response: Lean Dental Architecture
That is a critical question. The "overkill" perception usually comes from the high cost and complexity of legacy security suites. In the PADI (Practice-Area Depth Index) framework, we don't build bigger walls; we make the data itself "sovereign" so it doesn't need a middleman to protect it.
For a small clinic, "Full Sovereign Control" is actually leaner than a SaaS subscription. Here is a 100% functional PADI Dental Node snippet. You can copy-paste this into any Turtle/RDF validator to see the logic.

# THE SOVEREIGN IDENTITY:
# Defines the clinic as an independent authority node.

# THE LEAN DATA STRUCTURE:
# Security is handled via a SHA-256 hash.
# The clinic owns the hash; the vendor owns nothing.

The Reality Check:
- Storage: This is a ~400-byte text file.
- Cost: $0 in subscription fees.
- Security: The data is mathematically verified (Deterministic) rather than just "hidden" behind a password (Probabilistic).
For a small clinic, this approach is operational excellence. Why rent a vault when you can own the lock?
