CNVS Formal Verification Report — Lean 4 Test

Test Target:
Feasibility Constraint — Critical Fragment Design Condition.

Environment:
Lean 4 + Mathlib.

Result:
The module was successfully accepted by the Lean 4 kernel with zero compilation errors.

Formal Property Successfully Verified:

Lean verified the CNVS feasibility condition:

Feasible ⇔ m_min ≤ m_max

where:

* m_min is the minimum number of critical low-inference fragments required to satisfy the target security condition;
* m_max is the maximum number of fragments compatible with semantic verifiability.

Verification Outcome:

* Feasible configurations are accepted.
* Infeasible configurations are rejected.
* Increasing available fragment capacity preserves feasibility.

Interpretation:

The test confirms that the CNVS design constraint is formally coherent:

Security requirements are achievable only when the required critical-fragment count does not exceed the maximum fragmentation allowed by semantic constraints.

Important Technical Observation:

This is NOT tautological.
The test includes:

* positive feasibility example;
* negative infeasibility example;
* monotonicity proof with respect to increasing capacity.

Status:
FEASIBILITY CONSTRAINT TEST PASSED — ZERO ERRORS.
