Bound the existing passive preflight before Bash can discard NULs or accept unlimited configuration output. Preserve producer errors independently, isolate the byte reader from Python startup hooks, and keep the copied helper and mirrored help private and off the guest-agent channel.
Contract-Neutral: Operator diagnostics and existing help only; Proxmox polling, guest-agent coordination, APIs, storage and service behaviour are unchanged.

Do not report an absent lock or agent setting after malformed current-configuration output. Preserve passive bounded host reads, private output, unknown well-formed fields and the distinction from guest responsiveness or thaw.
Contract-Neutral: The operator-only helper now enforces its existing incomplete-read failure semantics; polling, guest-agent admission, API and storage contracts are unchanged.
Change-source: pulse-maintainer
Replace active guest probes with bounded passive host reads. Preserve errors and private configuration, distinguish setup from responsiveness, and put backup/thaw precautions ahead of troubleshooting. Exercise the actual helper and copied command with adverse and healthy controls.
Contract-Neutral: Operator diagnostics and existing help only; Proxmox polling, guest-agent coordination, APIs, storage and runtime behaviour are unchanged.
