Module metrics 

In-memory scan measurement records.

Runtime scope

• Build: opt-in via platform-models.
• Execution: host/library only; no repository runtime caller.
• Default termivar scan: no.
• Support: experimental data models.

Ratios in this module describe recorded counters. A response/request ratio is not a request success rate, and no outcome is inferred from it.

Structs

Thread-safe counters and caller-recorded phase duration samples.

MetricsSummary

Phase-specific raw measurements supplied by the caller.
