Formal Model
For a system S,
claim C,
evaluator conditions K,
and resource bounds B,
Structural Assurability is represented schematically as:
text
A(S, C, K, B)
The formalization does not reduce this object to a number.
Instead, it derives a profile of evidentiary capabilities available for the specified system and assurance context.
The conceptual flow is:
text
accessible evidence
∩
resource-feasible evidence
↓
obtainable evidence
↓
claim-material evidence
↓
evidentiary capabilities
↓
Structural Assurability profile
Each stage is represented separately so that access, resources, materiality, and capability semantics are not silently conflated.
