+## Scope

+- Project: src/Signer/StellaOps.Signer/StellaOps.Signer.Core/StellaOps.Signer.Core.csproj
+- Date (UTC): 2026-01-31
+
+## Findings
+- Single responsibility: file defines multiple types (CeremonyAuditEvents, CeremonyAuditEvent, CeremonyInitiatedEvent, CeremonyApprovedEvent, CeremonyExecutedEvent, CeremonyExpiredEvent, CeremonyCancelledEvent, CeremonyApprovalRejectedEvent); responsibilities may be bundled.
+- Dependency inversion: static utility types limit substitution; consider abstraction if behavior must vary.
+
+## Maintainability Notes
+- File length 234 lines; consider splitting for readability.
+
+## Recommendations
+- Split types into separate files grouped by responsibility.
+- Extract helpers to reduce file size and complexity.
+- Consider interface-backed abstraction if alternate implementations are needed.
