Drop-in build gate: verifies the built assembly against its ContractGuard API contract after every build, locally and in CI.

ContractGuard CLI: verifies built .NET assemblies against a prescribed API contract, extracts contracts from golden DLLs, and renders contracts as C# declarations.

Core engine for ContractGuard: the neutral signature model, contract JSON serialization, assembly metadata reader, and comparison engine.

Editor-time ContractGuard: the same contract comparison the CI gate runs, surfaced as compiler diagnostics with the same CG ids on the offending source line. Assistance, not the gate - the metadata check in CI... More information
