Term	Kind	Topic	What it is
Contract Testing	practice	API & Integration	Verifying that a provider satisfies the expectations each of its consumers actually relies on, without running all the services together.
Enterprise Integration Patterns EIP	practice	API & Integration	A catalogue of named, composable messaging patterns — router, translator, aggregator, splitter, filter, dead letter channel — that gives integration work a shared vocabulary.
Semantic Diffing of API Schemas	practice	Backward Compatibility	Comparing the published contract between builds and failing the build on a breaking change, so compatibility is mechanical rather than remembered.
Semantic Versioning SemVer	practice	API Versioning	A version scheme where the number itself states the compatibility promise — major for breaking, minor for additive, patch for fixes.
