attempt-3 pinned current_source_file to the metaprogram's defining module across the whole body lowering (lowerComptimeCall / monomorphizePackFn). That pin also covered caller-provided comptime $-arg nodes spliced into the body by substituteComptimeNodes — but those are CALLER-authored and must resolve in the caller's visibility context, not the callee's. Result: a caller-owned helper passed to an imported metaprogram errored "'<name>' is not visible". Fix: stamp each comptime $-arg node with the caller's source_file at the cpn build site (stampCallerSource, in lowerComptimeCall + monomorphizePackFn); lowerExpr switches current_source_file to a node's source_file when present, so the substituted subtree resolves against the caller while the surrounding callee code keeps the defining-module pin. No exemption / fall-open. Regression: examples/0738-modules-comptime-arg-caller-context.sx — a caller-owned helper passed as a comptime-ONLY $-arg through a namespaced import. Fail-before (attempt-3 binary): "'caller_name' is not visible". Pass-after: prints "hello world", exit 0. Comptime-only, so it does not exercise issue 0107. 0106 RESOLVED banner extended (point 3: body=defining context, substituted $-args=caller context). run_examples 473 -> 474; zig build test 412/412.
