`sx build --emit-obj` keeps the DWARF-bearing object so a debugger can step the binary, completing the deep-debug half of the trace story. - --emit-obj flag + TargetConfig.emit_obj. Implies -O0 (DWARF only emits at opt none/less); keeps the object at its link-time path .sx-tmp/main.o so the binary's debug map resolves to it; skips the Level-1 binary cache; reports the object path. macOS resolves via the debug map -> .o; Linux carries DWARF in the binary. Build-flow only, no runtime/codegen change. - tests/debug_stepping_smoke.sh (3e rung 1; macOS, lldb, not in run_examples): builds with --emit-obj, drives an lldb file:line breakpoint, asserts resolution + a source-mapped backtrace. Passing — proves the slice 1-2 DWARF drives real source-level stepping. (Also normalizes the 253 .exit trailing newline from the 3c --update.) Gates: zig build, zig build test, run_examples.sh -> 291 passed.
