+- Fresh state invalidated the stale kill plan: PID `1122414` was already absent.
+- PID `319572` is a valid, separate daemon for `/home/ralph/.pm2`; it was preserved.
+- PID `1148923` remains the sole `/root/.pm2` daemon and owns both root PM2 sockets.
+- Installed `/usr/local/bin/pm2` as a global root-call shim using Linux `flock -w 15`
+  and `timeout --signal=KILL 20 /usr/bin/pm2`. This covers watchdog, daily fleet,
+  service monitor, and crawler without modifying the dirty crawler worktree.
+- SHA-256: `a5a0be4e7f4aafc256e25a3943daac8d6fd30f734bf1f5935b7db40f989e73b6`.
+- Proof: 12 concurrent real `jlist` calls completed; forced contention failed closed
+  with exit `75`; no new daemon appeared; `pm2.pid=1148923` persisted.
+- Actual watchdog run advanced its heartbeat and reported `425` managed / `424` online.
+
+Rollback: remove `/usr/local/bin/pm2` to restore PATH resolution to `/usr/bin/pm2`.
