Main now pauses the actual PTY when a pane's renderer-pending backlog crosses the 256KB high watermark and resumes once it drains below the 32KB low watermark (wide hysteresis band so a draining queue cannot flap pause/resume per flush slice). node-pty pause() stops the pty fd read, so the kernel/ConPTY buffer fills and a flooding shell blocks on write — flood-induced buffered lag becomes shell blocking instead of unbounded main-process buffering (terminal-performance-initiative §5). Transport: new fire-and-forget pausePty/resumePty daemon notifications (protocol v19; 18 added to PREVIOUS_DAEMON_PROTOCOL_VERSIONS), routed DaemonServer -> TerminalHost -> Session -> subprocess pause()/resume(). LocalPtyProvider pauses node-pty directly. Router/degraded providers forward; IPtyProvider gains optional pauseProducer/resumeProducer. Safety invariants: - Lost-resume failsafe: daemon Session auto-resumes 5s after a pause with no matching resume; main re-asserts the pause at most once per 5s while still above the high watermark, so a lost resume can never wedge a shell and a sustained flood stays throttled. - Resume on every teardown path: Session kill/exit/dispose/detach; main releases on pty exit and on window-destroyed bookkeeping wipes; the adapter owes paused sessions a resumePty on the next connect after a socket drop. - Providers without support (SSH relay, legacy protocol <= v18) no-op silently, and the scrollback-scaled pending-output cap still bounds main memory when pause is unavailable. - Kill switch: PRODUCER_FLOW_CONTROL_ENABLED in ipc/pty.ts flips the whole mechanism off in one line. daemon-errors.ts is split out of types.ts to stay under the max-lines cap. Tests: watermark transitions/hysteresis/re-assert (controller unit), lost-resume failsafe + resume-on-kill/exit/dispose/detach (session), notification routing + v18 gating + reconnect owed-resume (adapter), direct pause/resume (local provider), and a flood test asserting pause fires once, pending stays bounded at HIGH + one chunk, and resume fires once after drain (ipc/pty).
