The executable overflow regression and a bounded Bash PTY probe show canonical terminals truncate long input before the size check. Read a bounded character count with echo held off, drain an invalid line before returning to the calling shell, and restore its modes on every exit. Pin maximum-size preservation, overflow history safety and terminal restoration.
Contract-Neutral: Repair bounded private terminal entry, overflow draining and mode restoration; no issuance, scope, install transport or response-shape delta.

Reuse the complete-download and preflight private-token entry boundary for both monitoring modes. Keep issued credentials separate and no-store, use the installer-owned token path in the diagnostic service reference, and reject structural unit injection before minting. Add executable root/sudo, history, transport, failure cleanup and systemd grammar regressions alongside the subsystem contracts.
