discovery(unwired-tracker): wire in delta_engine (tracker #1947 closed prematurely) #7798
Description
Unwired Module
File: autobot_shared/delta_engine.py
Closed tracker: #1947
Production callers: 0
Description
delta_engine in autobot_shared has zero production callers — tracker #1947 closed prematurely. Module not imported by any production code.
Source
Discovered by pipeline-scripts/audit-unwired-trackers.py run for GH#6872 (Phase D batch 5).
Action Required
Identify whether this module should be:
- Wired in — add an import/caller in the appropriate production module
- Deleted — if the feature was intentionally abandoned
- Deferred — file a wire-in issue with a concrete plan

Closing — DeltaEngine requires per-metric threshold configuration before it can be wired; no single natural caller exists without that configuration.
Analysis:
autobot_shared/delta_engine.pyprovidesDeltaEnginefor detecting significant metric changes. It requires per-metricMetricThresholdobjects (moderate_pct, critical_pct) to compute deltas.The most natural caller would be
metrics/system_monitor.py(which does static threshold checks) or a new metrics aggregation step. However:system_monitor.pycurrently does static value checks, not change-rate checks — wiring DeltaEngine requires redesigning the alerting pathAction: File a dedicated issue to design the metrics change-detection pipeline. Defining
MetricThresholdobjects and wiring DeltaEngine into the monitoring loop is a feature, not a simple wire-in.
