+"""Tests for the local-endpoint probe disk L2 cache in agent/model_metadata.
+
+Contract:
+- only SUCCESSFUL probes are persisted (failures never pin a verdict);
+- fresh disk entries serve cross-process (in-proc caches cleared);
+- entries expire after _LOCAL_PROBE_DISK_TTL_SECONDS;
+- corrupted cache files degrade to a miss;
+- detect_local_server_type and query_ollama_num_ctx both use it.
