Residual orphaned when #956 closed: CoreML (Phase B) and ROCm (Phase C) execution-provider wiring exists only as TODO comments (src/embedder/provider.rs:315,328) and a lib.rs "scaffolding present, wiring not yet complete" note. macOS ARM64 is a release target, so Phase B has real consumers. Sibling of open #1391 (NVRTX). Pattern note: closing umbrella issues silently orphans their phases — worth a checklist item when closing #1459/#1463.
