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.
