Use additional_paths for related chunks; each input retains its own snapshot and provenance. Returns original/derived digests, extraction byte ranges, emitted source maps, warnings and analysis_input inline. Structural splitting may fall back to one module; original names and runtime equivalence remain unknown. No application code execution. Requires util-linux prlimit; one worker, 1 GiB address-space ceiling, 120-second deadline, 64 MiB total input, 128 MiB output, 10000 entries and 8 MiB per diagnostic/report stream.",
