workstation: tmux sessions survive devvm reboots (save timer + boot restore) Viktor: emo's open web-terminal sessions must persist across reboots. Claude conversations were already durable on disk; the volatile part was the tmux wiring (which named session runs which conversation). t3-tmux-sessions save (5-min timer) snapshots every roster user's sessions to /var/lib/t3-tmux-state/<user>.tsv — conversation uuid taken from argv --resume (self-sustaining once restored) or the newest transcript in the cwd-slug project dir created after process start (fresh launcher sessions; claude does NOT hold its transcript fd open, so fd-sniffing was a dead end). t3-tmux-sessions restore (boot oneshot, also safe after partial loss) recreates missing sessions with claude --resume <uuid>. Reconciler self-heals both units' enablement. Verified live: emo's 5 sessions snapshotted with correct uuids; killed R730-cooling -> restore brought it back resuming the same conversation (context meter identical); other sessions untouched.
