…gate (ADR-1113) Plan A1+A2+A3: vendor interop.c/.h (+deband_params.c, version.c) from VMAFx/pelorus@835e097 as a pinned read-only mirror (DO-NOT-EDIT banner; append-only ABI) + scripts/sync-pelorus-interop.sh drift guard + the shared 7-vector conformance gate (7/7 pass). Vendored files excluded from clang-format + touched-file lint (must stay byte-identical). vmafx side stays Vulkan-free. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Summary
Vendors the Pelorus
interop.hside-data ABI into vmafx as a pinned read-only mirror + a sync-drift guard + the shared 7-vector conformance gate — the foundation (plan workstreams A1+A2+A3) for the bidirectional pelorus↔vmafx integration's data plane. The vmafx side stays Vulkan-free (it only parses a CPU side-data blob). Companion to the merged pelorus AVOption-contract PR (pelorus #4).Type
