Keep one ProcessOwnershipEvidenceOwner for each graceful/SIGKILL session and share it across active and terminal scoped scans. Require live token-verified evidence before stopping the owner, and retain structured cleanup failure diagnostics.
The real Ubuntu 24.04 Hopper clean-setup/CLI/MCP job passes, including owner exit, target reacquisition, idempotence and zero remaining descendants. Local verification passes 87 CI guards, 51 ownership controls, discovery of all 1,714 test files and full static checks.

Bind the owned demo helper to REA's private stdin stream and unwind child
cleanup on EOF during startup or analysis. Verify graceful and SIGKILL owner
exit through real CLI/MCP workflows and preserve unrelated processes.
