What Is Defined and What Is Deferred ​

The visibility architecture must not be read as an already completed concealment mechanism.

What is already an architectural claim ​

At the current stage, the following may already be considered defined:

• visibility is a regime rather than a flag;
• contour defines the boundaries of observability;
• not all internal content must be disclosed;
• the architecture admits a verifiable outcome without disclosing the full array.

What must not yet be presented as a completed mechanism ​

The deferred layer includes:

• the final privacy mechanism;
• the final cryptographic scheme;
• the detailed concealment strategy;
• the final security profile;
• the full specification of metadata and their disclosure.

This section already defines the architecture of visibility, but it does not fix the final concealment mechanism.
