data = json.load(open("config.json")) checker = KVCheckerFull(rules) if not checker.check(data): print("KV CHECKER FULL FAILED:") print(checker.report()) exit(1) else: print("All KV pairs validated successfully.") As systems become more dynamic, the "full" checker is evolving into continuous validation . Tools like Open Policy Agent (OPA) and Kyverno now perform real-time KV validation inside Kubernetes clusters. Instead of checking a static file pre-deployment, the cluster checks every write to etcd or ConfigMap at runtime.

"server": "port": 8080 becomes a virtual key server.port with value 8080 . This allows uniform rule application. A full checker is driven by a schema or rule file. This could be JSON Schema (for JSON data), a custom YAML ruleset, or even a simple Python dictionary defining expectations. data = json
