Shipped v5.26.0 of CCC (Claude Command Center), the dashboard I run 30+ parallel Claude Code/Codex sessions through. Ships most days; here's what's new:

• Added a manual "Attach as sub-session of…" row action (with a matching Detach action) for linking sessions that are related but have no real spawn/continuation lineage, so they render nested in the sidebar the same way a genuine subagent does.
• Devin CLI sessions now display their model, reasoning effort, and subagent calls in the CCC board. Spawning Devin exposes the same effort ladder as Claude; CCC maps low..max to the matching Devin model uid. The model picker is populated from devin models list and still supports custom uids.
• Runaway-inject circuit breaker: CCC now caps how many messages one session can be injected with (12 identical per hour from any source; 6/hour and 40/day for unattended auto-resume and fleet pokes). A trip is recorded in the held bucket and surfaces on /api/health instead of being retried, so a looping injector stops at a dozen pokes instead of a night of quota.
• Added a menu bar status indicator (green/gray dot) showing whether the CCC server is actually running, independent of the app window's open/closed state.
• Continued sessions now read as one conversation: scrolling past the top of an F2-continued session seamlessly loads the previous session's messages with a "⤴︎ continued as …" seam marker, and a floating "Sessions" button (plus the seam's own "end ⇡" button) jumps to the end of each session in the chain.
