+## 2026-03-21 - 4.14.1 - fix(remoteingress edge/hub crash recovery)
+prevent duplicate crash recovery listeners and reset saved runtime state on shutdown
+
+- Removes existing exit listeners before re-registering crash recovery handlers for edge and hub processes.
+- Clears saved edge and hub configuration on stop to avoid stale restart state.
+- Resets orphaned edge status intervals and restarts periodic status logging after successful crash recovery.
+
 ## 2026-03-20 - 4.14.0 - feat(quic)
 add QUIC stability test coverage and bridge logging for hub and edge
