Core 1.0.7 custom-host compatibility with SDK 1.0.5 — 2026-10-17¶

Measured against Core 1.0.7 source commit 20d837a2f735c1c785db6593b58ebe10b3dd9f05 and its official CLI package. The Core source tree was 0df0b96852f472ff0a80f5c3a88ded0f61215c81.

Previously built Hello and JsonRpc provider assemblies targeting the published Vouchfx.Sdk 1.0.5 were run unchanged by a custom ScenarioRunner host. The host's measured build, runtime and driver checks each exited 0 in the .NET SDK 10.0.401 environment. Runtime results were two business assertions passed, zero other verdicts and one loaded Vouchfx.Sdk 1.0.7.0 identity. Five official Core DLL hashes matched between the installed CLI and package bytes; the two SDK 1.0.5 provider references and their accepted binary SHA-256 values remained unchanged.

This is custom-host ABI compatibility evidence only. It does not test external provider loading by the stock CLI, or establish a new SDK 1.0.5 package release.
