Split journal think task queueing by mode so daily, segment, flush, activity, and weekly work no longer serialize behind one literal think partition. This keeps startup/daily catchup from blocking live segment-thinks. Use `_command_partition` in runner.py as shared source of truth; `TaskQueue.get_command_name` delegates to it. Think partitions use bare names: daily/segment/flush/activity/weekly. The weekly-agents 30m max_runtime now applies only to weekly; before, the broad think key applied it to all journal think runs. Operators with hand-edited schedules keyed against literal `think` will lose that cap and should re-key against the specific think mode. Clean break per CLAUDE.md §8: no fallback alias for old `"think"` cmd_name. Allowing two parallel think modes increases LLM load; that is acknowledged and accepted.
