+Use atomic promote (all three layers — cadence, definitions, fleet, sync):

 ```bash
-# After coulomb-loop merge — disable daily defs, enable weekly crons
-cd ~/activity-core && make sync-activity-definitions  # or equivalent sync command

+`--fleet-only` skips cadence/definition transforms when those are already committed.
+Omit `--fleet-only` for a full stabilize→operate promotion on future loops.

+
+After regulator approval, promote all three scheduling layers in one step:
+
+```bash
+kaizen-agentic schedule promote \
+  --engagement-repo /home/worsch/coulomb-loop \
+  --engagement coulomb-loop \
+  --to-phase operate \
+  --activity-core /home/worsch/activity-core

+kaizen-agentic schedule promote \
+  --engagement-repo /home/worsch/coulomb-loop \
+  --fleet-only \
+  --activity-core /home/worsch/activity-core
+```
+
+Layers: (1) `loops/*/cadence.yml`, (2) `activity-definitions/` + activity-core sync,
+(3) pilot `.kaizen/schedule.yml` via roster.
