"""
Adversarial Symbolic Stripping Test — Research Stack Foundations
=================================================================

Strips all semantic content from the Research Stack framework to test
whether the mathematical structure computes correctly as pure number fields.

Purpose:
- Verify F01-F12 are mathematically sound, not just philosophically coherent
- Test that removing names/symbols doesn't break computation
- Identify which claims are purely semantic vs mathematically formalized

Method:
1. Replace all named variables with indexed number fields (N_0, N_1, ...)
2. Strip all biological/physical/cognitive terminology
3. Test if equations still compute deterministically
4. Verify output invariants hold without semantic labels

This is the ultimate test: Can the framework compute without "meaning"?

The Research Stack framework CANNOT currently pass adversarial symbolic 
stripping. The F01-F12 foundation kernels exist as conceptual vocabulary 
but lack mathematical formalization required for pure numerical computation.

To pass this test, each F01-F12 must provide:
1. Complete field definitions (types, dimensions, constraints)
2. Pure numerical operations (no semantic content)
3. Deterministic computation (same inputs → same outputs)
4. Invariant checking (mathematical, not semantic)

The Harmon Constant correctly FAILS stripping — it contains semantic
content in its "operation" field ("bypass_boundary_layer"), revealing it
as pseudoscience rather than formalized mathematics.

CONCLUSION: Framework is conceptually mature but mathematically 
incomplete. Requires F01-F12 formalization to pass adversarial testing.
