+# Night chain (2026-10-03), started detached so it survives the Claude Code session.
+# 1. When filter worker W6A (PID 57253) ends: start W7B (DeepSeek reruns, list in runs/stage1/w7b.txt).
+# 2. When the T01 test (PID 59414) and all DeepSeek workers end: check T01 in runs/stage1/baseline.json.
+#    No harness error -> remove the T01 entry (it ran with the old budget 40) and run all 25 subset tasks.
+# 3. macOS notification at each end. Log: runs/stage1/night_chain.log
