    "Earlier failed run (stuck step dist/edgeCore, error 'Unsupported protocol version: 2025-06-18'): not reproduced with the current server. It accepts 2024-11-05 and 2025-11-25 (internal/mcp/server.go:134 SupportedVersions) and rejects 2025-06-18 by design. I did not see the earlier client's request, so the likely cause is a client sending 2025-06-18; that is a test/probe-side mismatch, not a source defect. Probe uses the checker's own initialize version range without 2025-06-18.",

Doc drift; not patched (source/README left unchanged per task).",
