+# SOLID Review - SignatureProfileTests
+## Scope
+- File: src/Cryptography/__Tests/StellaOps.Cryptography.Tests/CryptographyModelTests.cs
+- Project: src/Cryptography/__Tests/StellaOps.Cryptography.Tests/StellaOps.Cryptography.Tests.csproj
+- Date (UTC): 2026-01-31
+
+## Findings
+- Single responsibility: file defines multiple types (SignatureProfileTests, SignatureTests, SignatureResultTests, VerificationResultTests, CertificateValidationResultTests); responsibilities may be bundled.
+
+## Maintainability Notes
+- File length 318 lines; consider splitting for readability.
+
+## Recommendations
+- Split types into separate files grouped by responsibility.
+- Extract helpers to reduce file size and complexity.

+- Project: src/Cryptography/__Tests/StellaOps.Cryptography.Tests/StellaOps.Cryptography.Tests.csproj
+- Date (UTC): 2026-01-31
+
+## Findings
+- Single responsibility: file defines multiple types (SoftHsmTestFixture, SoftHsmConfig); responsibilities may be bundled.
+- Dependency inversion: static utility types limit substitution; consider abstraction if behavior must vary.
+
+## Maintainability Notes
+- Multiple types in one file can blur ownership boundaries.
+
+## Recommendations
+- Split types into separate files grouped by responsibility.
+- Consider interface-backed abstraction if alternate implementations are needed.
