Run the existing failure-only native Linux trace through pinned GDB, following the compiler shell wrapper so package DB and -B flags remain intact. Fetch the debugger only from caches within the existing overall bound and preserve diagnostic exit failures. Capture bounded stacks, registers, PC disassembly and mappings without environment or core dumps. Validation: 41 generated-wrapper forwarding/status cases and three extracted workflow-shell cases pass; debugger cache-only fetch succeeds. The local Rosetta Linux VM cannot ptrace the child, and the bounded native ARM control stopped at metadata, so actual native fault capture remains a CI validation step.
