// These primitives run in the comptime evaluator (`abi(.compiler)`), serviced by
// `comptime_vm.callCompilerFn`. They are the building blocks of the sx-driven
// build pipeline (Phase 5); the default `build` implementation that orchestrates
// them lives in `modules/build.sx`. They are reached 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).

// The C companion object files for this build (`#import c { #source ... }`,

// the linker. Answered from the compiler's accumulated build state.

// the proven linker (Option B); the sx driver orchestrates. Not fallible (the
// build callback isn't): a link failure fails the build directly.
