The compiler emits the sx object eagerly (the Zig driver, before the post-link callback), so emit_object is a QUERY (not an action): it returns the path from a new BuildConfig.object_path field main.zig forwards — no driver vtable. This completes the build-pipeline QUERY primitives (emit_object / c_object_paths / link_libraries); only link (the genuine action) remains for the vtable step. Extended examples/1662 to also assert emit_object().len > 0. 703/0 both gates.

// These run in the comptime evaluator (`abi(.compiler)`), serviced by

// `comptime_vm.callCompilerFn`. They are called from the post-link build driver

// (a callback registered via `set_post_link_callback`), which always runs on the
|

// comptime VM (`core.invokeByFuncId`) — the VM, unlike the legacy interpreter,
|
|
// can allocate/grow the `List`s the driver builds (issue 0141).
