Join identity-verified PTY family cleanup and native exit before workspace removal, retaining failed cleanup capabilities for retry. Replace duplicate kill-and-reject loops with shared process ownership and deadlines.
Capture configuration before setup using owned file handles and compare raw bytes. Preserve interactive cancellation, terminal restoration, redirected output, and selected inputs; remove the test-only forwarding export. Verified 122 focused cases, 9 README cases, build, static checks, docs, discovery, and duplication at 3.58%.
Use exact discovered test identities, production MCP sessions and byte-exact setup backups. Add CLI signal cleanup coverage and independent Ghidra, Go and firmware verification assertions; prune redundant test configuration and preserve platform limits.
