 ### Prediction Metrics
-- `aeop_prediction_failure_probability` - Predicted failure probability (0-1)
-- `aeop_prediction_confidence` - Prediction confidence level
-- `aeop_prediction_time_to_failure_seconds` - Estimated time until failure
-- `aeop_prediction_preemptive_migrations_total` - Migration count
+- `sentinel_prediction_failure_probability` - Predicted failure probability (0-1)
+- `sentinel_prediction_confidence` - Prediction confidence level
+- `sentinel_prediction_time_to_failure_seconds` - Estimated time until failure
+- `sentinel_prediction_preemptive_migrations_total` - Migration count
 
 ### Partition Metrics
-- `aeop_partition_detected` - Partition status (0/1)
-- `aeop_partition_duration_seconds` - Current partition duration
-- `aeop_consensus_is_leader` - Leader status
-- `aeop_partition_autonomous_decisions_total` - Autonomous decisions made
+- `sentinel_partition_detected` - Partition status (0/1)
+- `sentinel_partition_duration_seconds` - Current partition duration
+- `sentinel_consensus_is_leader` - Leader status
