* fix(daemon): pause producers when stream backlogs grow * fix(daemon): reset stream backpressure on socket replacement * docs(daemon): point retention audit at current reproducer * test(daemon): validate stream retention audit outcomes * fix(daemon): bound the stream producer stall and leave a visible gap Stream backpressure pauses a session's PTY with no deadline: the only un-pause comes from the consumer draining, so a half-open peer that stops reading without closing freezes the shell for the rest of the session. Arm a 60s watchdog on the false->true stream-pause transition (not on the re-assertions refresh() makes for neighbouring sessions). On fire, mark the session stall-released: it becomes keep-tail droppable, its backlog is thinned behind a dataGap, and the producer runs again. The existing dataGap path makes the renderer restore that pane from the daemon's snapshot, so the user sees the terminal jump to current rather than sit frozen. The mark clears once the session's last byte leaves the daemon, restoring ordinary pausing. Nothing here reports a process exit - loss of contact with a consumer is not evidence about the child. Also enable TCP keepalive on the stream socket so a genuinely dead peer closes and onStreamDisconnected clears the pause. * test(daemon): put each casting SAFETY: directive on one line `oxlint-disable-next-line` covers only the line directly after it, so a rationale wrapped onto a second comment line suppressed nothing and the casts failed the changed-code quality gate. Drop the remaining JSON.parse cast for an annotated binding. --------- Co-authored-by: m4air <m4air@Mac.localdomain> Co-authored-by: Neil <neil@stably.ai>
