Production crash diagnostics measured ~128 `git worktree list` execs/min (9,400 in one 80-minute session, ~16% of wall-clock in git subprocesses): the resolved-worktree scan fans out over every registered repo on a 30s cache TTL, and most registered repos on the affected installs were agent-CLI scratch repos (~/.codex-tmp capsules, vendor imports, skill checkouts) that need no freshness. Classify agent-scratch repo roots with a curated shared matcher and stamp their scan-cache entries with a 5-minute TTL instead of 30s. Orca-driven mutations still bypass the TTL via the per-repo generation bump, so only passive pickup of external changes slows for scratch repos. Expected steady-state reduction on the measured install: ~82% fewer git spawns.
