Research direction
Start by locating the path-index cache implementation and the project’s existing OpenTelemetry instrumentation patterns. Identify where cache misses, idle-view evictions, and cache-full failures occur, then add low-cardinality metrics for those events. Done means each event is measurable without high-cardinality labels; the issue does not name specific files or tests.
Written by the indexing model from the issue text.
Description
Add low-cardinality OpenTelemetry metrics for path-index cache misses, idle-view evictions, and cache-full failures. Use the measurements to guide cache capacity, bounded waiting, prewarming, and future cache-policy decisions.
