Run the accepted Unix teardown functions on fresh public Linux x64 and ARM64 CI, with real stop refusal, socket activation, batch reactivation and independent process/file readback. Retain bounded source-bound phase and owned-cleanup receipts; keep synthetic revocation separate from installed TLS, signed-agent and Windows acceptance. Change-source: pulse-maintainer
