Module distribution 

Distribution fitting and sampling utilities. Distribution fitting and sampling for workload latency inputs.

This module converts percentile-based or sample-based latency observations into a service-time distribution usable by the optimizer and simulation layers.

Main entrypoints:

• LatencyDistribution::fit
• LatencyDistribution::sample_ms
• LatencyDistribution::percentile_ms
• LatencyDistribution::mean_ms

Selection rules:

• percentile-only workloads fit one of the supported parametric models
• raw_samples_ms forces empirical fitting regardless of the requested model
• fitted distributions are reused by Monte Carlo and queueing helpers

Structs

EmpiricalCdf

Empirical cumulative distribution built from raw latency samples.

Enums

LatencyDistribution

Service-time distribution used during simulation and queue estimation.
