CostEffectiveVerification.lean — Cost-Effective Verification Target Theorem
|
||
|
||
This module formalizes the cost-effective verification target: prove that the manifold
|
||
can group ontologically different systems together when they share the same behavioral
|
||
operator, rather than trying to prove the full grand model.
|
||
|
||
Per AGENTS.md §1.6: No proof placeholders in committed code.
|
||
Per AGENTS.md §1.4: Uses Q16_16 fixed-point for hardware-native computation.
|
||
Per AGENTS.md §2: PascalCase types, camelCase functions.
|
||
Per AGENTS.md §4: All defs must have eval witnesses or theorems.
