Activity summary: 29 messages across 2 sessions on transcript management and system administration.

Sessions and Activity

io (1 session): Session transcript backup and archival work. User initiated investigation into backup mechanisms for Claude Code session transcripts. Delegated agent task to check whether automated backup process exists (none found). Investigated CLAUDE_.md for backup practices (none documented). Results: live transcripts at ~/.claude/projects/ are solid and gapless (2026-04-10 through today), but no automated backup mechanism exists; /mnt/ssd/backup/me/.claude/ is a stale one-off copy from May 14, not a working backup. Key finding: no cron/timer/script for recurring backups, despite significant risk of loss.

nixos (1 session): System administration session involving SSD setup, file migration, and storage reorganization. Work included mounting new SSD, auditing what's on it, deciding what to delete vs. migrate. Specific work: moving LLM models from home drive to external USB, deleting unnecessary files (enso, openvscode-server, potentially problematic ~/.wine state with mystery rsync mirrors). Investigation of disk usage and safe deletion patterns.

Observations

• Day had two parallel infrastructure concerns: backup/archival (discovered lack of automation) and storage management (active problem-solving)
• Transcript backup gap is a real risk identified but not yet resolved (user noted for later action)
• Storage migration was methodical: audit → decide → move, with safety checks for symlinks/hardlinks
• Both sessions were diagnostic/exploratory with minimal new implementation

Projects Touched

• io — transcript management, backup infrastructure
• nixos — storage administration, hardware/SSD setup
